Jeep WARNING LIGHTS AND MESSAGES Guide
The warning/indicator lights will illuminate the instrument panel together with a dedicated message and/or acoustic signal when applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to the information contained in the Owner’s Manual, which you are advised to read carefully in all cases. Always refer to the information in this chapter in the event of a failure indication. All active telltales will display first if applicable. The system check menu may appear differently based on equipment options and current vehicle status. Some telltales are optional and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to indicate a fault with the airbag and will turn on for four to eight seconds as a bulb check when the ignition is placed in the ON/RUN or ACC/ ON/RUN position. This light will illuminate with a single chime when a fault with the airbag has been detected, it will stay on until the fault is cleared. If the light is not on during startup, stays on, or turns on while driving, have the system inspected at an authorized dealer as soon as possible.
Brake Warning Light
This warning light monitors various brake functions, including brake fluid level and parking brake application. If the brake light turns on it may indicate that the parking brake is applied, that the brake fluid level is low, or that there is a problem with the Anti-Lock Brake System reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system malfunction or that a problem with the Brake Booster has been detected by the Anti-Lock Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light will remain on until the condition has been corrected. If the problem is related to the brake booster, the ABS pump will run when applying the brake, and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure of a portion of the hydraulic system. A leak in either half of the dual brake system is indicated by the Brake Warning Light, which will turn on when the brake fluid level in the master cylinder has dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp cornering manoeuvres, which change fluid level conditions. The vehicle should have service performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system may have failed. It will take longer to stop the vehicle. You could have a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake Warning Light will turn on along with the ABS Light. Immediate repair to the ABS is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch from the OFF position to the ON/RUN position. The light should illuminate for approximately two seconds. The light should then turn off unless the parking brake is applied or a brake fault is detected. If the light does not illuminate, have the light inspected by an authorized dealer.
The light also will turn on when the parking brake is applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the battery is not charging properly. If it stays on while the engine is running, there may be a malfunction with the charging system. Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system or a related component.
Door Open Warning Light
This indicator will illuminate when a door is ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single chime.
Electric Power Steering (EPS) Fault Warning Light

WARNING!
Continued operation with reduced assistance could pose a safety risk to yourself and others. Service should be obtained as soon as possible.
Electronic Throttle Control (ETC) Warning Light
This warning light will illuminate to indicate a problem with the ETC system. If a problem is detected while the vehicle is running, the light will either stay on or flash depending on the nature of the problem. Cycle the ignition when the vehicle is safely and completely stopped and the transmission is placed in the PARK position. The light should turn off. If the light remains on with the vehicle running, your vehicle will usually be drivable; however, see an authorized dealer for service as soon as possible.
NOTE:
This light may turn on if the accelerator and brake pedals are pressed at the same time.
If the light continues to flash when the vehicle is running, immediate service is required and you may experience reduced performance, an elevated/rough idle, or engine stall and your vehicle may require towing. The light will come on when the ignition is placed in the ON/RUN or ACC/ON/RUN position and remain on briefly as a bulb check. If the light does not come on during starting, have the system checked by an authorized dealer.
Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condition. If the engine coolant temperature is too high, this indicator will illuminate and a single chime will sound. If the temperature reaches the upper limit, a continuous chime will sound for four minutes or until the engine can cool; whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the Air Conditioning (A/C) system is on, turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the temperature reading does not return to normal, turn the engine off immediately and call for service.
Hood Open Warning Light
This indicator will illuminate when the hood is ajar/open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single chime.
Oil Pressure Warning Light
This warning light will illuminate, and a chime will sound, to indicate low engine oil pressure. If the light and chime turn on while driving, safely stop the vehicle and turn off the engine as soon as possible. After the vehicle is safely stopped, restart the engine and monitor the Oil Pressure Warning Light. If the Oil Pressure Warning Light is still illuminated, turn the engine OFF and contact an authorized dealer for further assistance. Do not operate the vehicle until the cause is corrected. If the light is no longer illuminated, the engine can be operated but it is recommended to take the vehicle to an authorized dealer as soon as possible.
Do not operate the vehicle until the cause is corrected. This light does not indicate how much oil is in the engine. The engine oil level must be checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil temperature is high. If the light turns on while driving, stop the vehicle and shut off the engine as soon as possible. Wait for the oil temperature to return to normal levels.
Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger seat belt is unbuckled. When the ignition is first placed in the ON/RUN or ACC/ON/RUN position and if the driver’s seat belt is unbuckled, a chime will sound and the light will turn on. When driving, if the driver or front passen-ger seat belt remains unbuckled, the Seat Belt Reminder Light will flash or remain on continuously and a chime will sound.
Rear Seat Belt Reminder Indicator Light — If Equipped With A Base Instrument Cluster
This light indicates when a rear seat belt is unbuckled in the second row. When the ignition is first placed in the ON/RUN or ACC/ON/RUN position, and if a seat belt in the second row is unbuckled, a light corresponding to the specific seat will turn on in the upper right portion of the instrument cluster display, momentarily replacing the configurable corner information. If a second-row seat belt that was buckled at the start of the trip is unbuckled, the Rear Seat Belt Reminder Light will change from the buckle to the unbuckled symbol, and a chime will sound.
Transmission Temperature Warning Light — If Equipped
This warning light will illuminate to warn of a high transmission fluid temperature. This may occur with strenuous usage such as trailer towing. If this light turns on, stop the vehicle and run the engine at idle or slightly faster, with the transmission in PARK (P) or NEUTRAL (N), until the light turns off. Once the light turns off, you may continue to drive normally. If Manual transmission is equipped, this warning will illuminate to warn of high clutch temperature. This may occur with driver misuse of the clutch pedal resting foot on the clutch pedal or partially engaging the clutch for a longer duration. If the light turns on, it will be with an additional CLUTCH HOT message. Stop the vehicle safely and run the engine at idle with the transmission gear in NEUTRAL (N) until the light turns off. Once the light turns off, follow the mes-sage displayed in the instrument cluster.
WARNING!
If you continue operating the vehicle when the Trans-mission Temperature Warning Light is illuminated you could cause the fluid to boil over, come in contact with hot engine or exhaust components and cause a fire. If you continue to operate the vehicle when the CLUTCH HOT message is displayed or the Transmission Temperature Warning Light is illuminated, you could cause the clutch to overheat and cause a fire. If a Service Transmission message is displayed please seek dealer service as soon as possible, this could indicate clutch damage and excessive slippage.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated will eventually cause severe transmission damage or transmission failure. If you continue to operate the vehicle when the CLUTCH HOT message is displayed or the Transmission Temperature Warning Light is illuminated, you could cause the clutch to overheat and cause severe clutch damage, transmission damage or failure.
