Things to Know Before Starting Your Vehicle

Before starting your 2012 Jeep Grand Cherokee‚ familiarize yourself with its key features and safety systems. Ensure that the parking brake is engaged‚ the transmission is in park‚ and the vehicle is in a safe and level location. Check the engine oil level‚ coolant‚ and tire pressure. Review the owner’s manual for specific instructions on starting your vehicle and its various components. Pay attention to warning lights and indicators to ensure a smooth and safe driving experience.

A Word About Your Keys

Your 2012 Jeep Grand Cherokee utilizes a keyless ignition system‚ featuring a Key Fob with Remote Keyless Entry (RKE). The Key Fob serves as your ignition key and houses the remote control for locking and unlocking your vehicle’s doors. It also features a panic alarm button for emergencies. The system relies on a wireless ignition node (WIN) for starting the engine and is designed to prevent unauthorized access‚ with a Sentry Key Immobilizer system preventing the vehicle from starting with an invalid key.

Key Fob

The Key Fob is your primary interface for controlling your vehicle’s ignition and security features. It features a unique design with a square end that inserts into the ignition switch located on the instrument panel. The key fob can be rotated to various positions‚ including “OFF‚” “ACC” (accessory)‚ “ON‚” and “START‚” allowing you to control the vehicle’s power and functions. The key fob also includes a small‚ removable emergency key for situations where the electronic system might fail.

Removing Key Fob From Ignition

To remove the Key Fob from the ignition‚ ensure the vehicle’s transmission is in the “PARK” position. Turn the Key Fob to the “OFF” position. You can then gently pull the Key Fob out of the ignition switch. The Key Fob is designed for a secure fit‚ so you may need to apply a slight amount of force while maintaining a firm grip to remove it. Once the Key Fob is removed‚ ensure it is stored safely and not left within the vehicle’s reach.

Key-In-Ignition Reminder

The Key-In-Ignition reminder is a safety feature designed to alert you if the Key Fob is left in the ignition. When the Key Fob is in the “OFF” or “ACC” position‚ the reminder will sound‚ reminding you to remove the Key Fob from the ignition. This feature helps prevent accidental vehicle theft and ensures the vehicle is properly secured when unattended. The reminder sound is audible and distinct‚ ensuring it effectively alerts you to the presence of the Key Fob in the ignition.

Replacement Keys

If you lose your Key Fob‚ or it becomes damaged‚ you can obtain a replacement from an authorized Jeep dealer. The dealer will need to program the new Key Fob to your vehicle’s Sentry Key Immobilizer system. This system prevents unauthorized use of your vehicle and requires a valid Key Fob to start the engine. Replacement keys are essential for maintaining access to your vehicle and ensuring its security. The dealer can also provide additional Key Fobs if you need them for other family members or authorized drivers.

Customer Key Programming

Programming additional Key Fobs or Remote Keyless Entry (RKE) transmitters is a process that should be performed by an authorized Jeep dealer. The dealer has specialized equipment and knowledge to ensure the correct programming of the keys to your vehicle’s security system. Attempting to program keys yourself could result in errors or security vulnerabilities. It’s crucial to rely on the expertise of trained professionals for this procedure‚ ensuring the proper functioning of your vehicle’s security features.

Rearming The System

To rearm the Vehicle Security Alarm after it has been disarmed‚ simply close all doors‚ the hood‚ and the liftgate. The alarm will automatically rearm after approximately 30 seconds. If the alarm is disarmed and the doors‚ hood‚ or liftgate are left open for an extended period‚ the alarm will not rearm. If you wish to rearm the system immediately‚ press the LOCK button on the Key Fob. The system will acknowledge the arming with audio and visual signals‚ including a horn chirp‚ flashing headlights‚ and possibly flashing park lamps or turn signals for three minutes.

To Disarm The System

To disarm the Vehicle Security Alarm‚ you can use either the Key Fob or the Passive Entry Door Handle. To disarm the system with the Key Fob‚ simply press the UNLOCK button once. The horn will chirp once to acknowledge the signal. To disarm the system with the Passive Entry Door Handle‚ press the LOCK button with a valid Key Fob available in the same exterior zone. The system will respond with a single horn chirp. You can also disarm the system by inserting the Key Fob with RKE transmitter into the ignition switch‚ which disables the system from responding to any button presses from that RKE transmitter.

Tamper Alert

The Tamper Alert feature is designed to protect your vehicle from unauthorized entry. When the Vehicle Security Alarm is armed‚ the interior power door lock switches will not unlock the doors. If something has triggered the Vehicle Security Alarm in your absence‚ the horn will sound three times and the exterior lights blink three times when you unlock the vehicle. This indicates that the alarm has been activated and the vehicle may have been tampered with. It is recommended to inspect the vehicle for any signs of damage or intrusion.

Remote Keyless Entry (RKE)

The Remote Keyless Entry (RKE) system allows you to lock and unlock your vehicle’s doors‚ trunk‚ and tailgate from a distance using the Key Fob. The RKE system also includes a Panic Alarm feature‚ which can be used to attract attention in an emergency situation. The RKE system is designed to provide convenience and security. You can use the RKE transmitter to unlock the doors‚ lock the doors‚ and even program additional transmitters if needed. The RKE system is a valuable feature that enhances your overall driving experience.

To Unlock The Doors

Unlocking your Jeep Grand Cherokee’s doors with the Remote Keyless Entry (RKE) system is simple. Press and release the UNLOCK button on the RKE transmitter once to unlock the driver’s door. To unlock all four doors‚ press and release the UNLOCK button twice. You can also use the exterior Passive Entry Door Handle with a valid Key Fob available in the same exterior zone. This feature allows you to unlock the doors by simply pulling the door handle. The RKE system provides you with convenient and secure access to your vehicle.

To Lock The Doors

Locking your Jeep Grand Cherokee’s doors is just as easy as unlocking them. Simply press and release the LOCK button on the RKE transmitter to secure all four doors. The turn signal lamps will flash‚ and a gentle chirp from the horn will confirm that your vehicle is locked. For added security‚ make sure to remove all Key Fobs from the vehicle and lock all doors when leaving it unattended. By following these simple steps‚ you can ensure your Jeep Grand Cherokee remains safe and secure at all times.

Programming Additional Transmitters

If you need to add more Remote Keyless Entry (RKE) transmitters to your Jeep Grand Cherokee‚ you’ll need to program them. This process can be performed at an authorized Jeep dealership. It’s important to note that the programming process might vary depending on the specific model year and trim level of your Grand Cherokee. Be sure to consult your owner’s manual or contact a Jeep dealer for detailed instructions on programming additional RKE transmitters for your vehicle.

How To Use Remote Start

The Remote Start feature on your 2012 Jeep Grand Cherokee allows you to start your vehicle remotely using the key fob. To activate Remote Start‚ press and release the REMOTE START button on the key fob twice within five seconds. However‚ several conditions must be met for the Remote Start to work‚ including a fully engaged parking brake‚ the vehicle being in PARK‚ and the hood being closed. The engine will start and run for a limited time‚ usually around 15 minutes‚ or until the vehicle’s battery level falls below a certain point. Consult your owner’s manual for detailed instructions and limitations regarding Remote Start.

Door Locks

Your 2012 Jeep Grand Cherokee offers a range of door locking options for your convenience and security. The vehicle is equipped with power door locks that are controlled by switches located on each front door panel. These switches allow you to lock or unlock all doors with a single touch. Additionally‚ you can utilize the Remote Keyless Entry (RKE) system to lock and unlock doors remotely using the key fob. The RKE system offers added features like a “Panic Alarm” that can be activated to sound the horn and flash the lights in an emergency situation. For detailed instructions on using the door lock features‚ consult your owner’s manual.

Power Door Locks

Your 2012 Jeep Grand Cherokee is equipped with power door locks for easy and convenient operation. These locks are controlled by switches located on each front door panel. By pressing the appropriate switch‚ you can lock or unlock all doors simultaneously. This feature allows for quick and effortless door locking and unlocking‚ enhancing both convenience and security. In addition to the power door lock switches‚ your vehicle may also have a power door lock switch on the driver’s door armrest. This switch enables you to lock or unlock the doors from the driver’s seat‚ providing added comfort and accessibility. For detailed instructions on using the power door lock features‚ consult your owner’s manual.

Seat Belt Pretensioners

Your 2012 Jeep Grand Cherokee is equipped with seat belt pretensioners‚ a safety feature designed to enhance occupant protection during a collision. These pretensioners are integrated into the front seat belts and work in conjunction with the vehicle’s airbags. In the event of a sudden deceleration‚ such as a collision‚ the pretensioners quickly remove any slack in the seat belts‚ drawing the occupants securely against the seats. This action helps to minimize forward movement and potential injuries during an impact. By reducing the distance an occupant travels during a collision‚ seat belt pretensioners can significantly improve the effectiveness of the seat belts and overall safety in a crash.

Event Data Recorder (EDR)

Your 2012 Jeep Grand Cherokee is equipped with an Event Data Recorder (EDR)‚ also known as a “black box‚” which is a device that records certain vehicle data in the moments leading up to and during a collision or other critical event. This data can include information such as vehicle speed‚ brake application‚ steering wheel position‚ and seat belt usage. The EDR is designed to help investigators understand the circumstances of a crash and potentially improve vehicle safety in the future. It is important to note that the EDR does not record any personal or identifying information about the driver or passengers. The data recorded by the EDR can only be accessed by authorized personnel‚ such as law enforcement or accident investigators‚ using specialized equipment.

Wind Buffeting

Wind buffeting is a phenomenon that can occur in vehicles‚ particularly SUVs like the Jeep Grand Cherokee‚ when traveling at high speeds. It is characterized by a shaking or vibrating sensation in the cabin‚ often accompanied by noise. This is caused by wind turbulence interacting with the vehicle’s body‚ creating pressure differences that can lead to instability. Wind buffeting can be more pronounced in vehicles with a larger or more boxy shape‚ or when windows or sunroof are open. To minimize wind buffeting‚ ensure all windows and sunroof are closed securely‚ especially at higher speeds. In some cases‚ aftermarket wind deflectors or other modifications may help reduce the severity of the problem.

Vehicle Security Alarm

Your 2012 Jeep Grand Cherokee is equipped with a Vehicle Security Alarm designed to deter theft and provide peace of mind. When the alarm is armed‚ sensors monitor the vehicle for unauthorized entry or movement. If an intrusion is detected‚ the alarm will sound‚ flashing lights will activate‚ and a notification will be sent to the key fob. The alarm system can be armed and disarmed using the key fob’s buttons‚ or by using the vehicle’s door locks. It is important to ensure the alarm is functioning properly and that the key fob is within range for reliable operation. Refer to the owner’s manual for detailed instructions on using and programming the Vehicle Security Alarm.

Using The Panic Alarm

The Panic Alarm feature on your 2012 Jeep Grand Cherokee is designed for emergencies. If you find yourself in a dangerous situation or need to attract attention‚ you can activate the Panic Alarm by pressing and holding the PANIC button on your key fob for at least one second. This will trigger the vehicle’s horn to sound continuously and the headlights to flash. The Panic Alarm will remain active until you press the LOCK button on the key fob or deactivate it by cycling the ignition switch to the ON position. Remember to use this feature responsibly and only in genuine emergencies.
