2008 Jeep Liberty Owner's Manual - Page 197

INSTRUMENT PANEL AND CONTROLS 197 cluster comes on when the ignition switch is turned to the "ON" position. It should go out with the engine running. If the "ESP/BAS Warning Lamp" comes on continuously with the engine running, a malfunction has been detected in either the ESP or the BAS system, or both. If this light remains on after the several ignition cycles, and the vehicle has been driven several miles at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected.(See page 314 for more information.) NOTE: The "ESP/BAS Warning Lamp" comes on momentarily each time the ignition switch is turned ON. NOTE: Each time the ignition switch is turned ON, the ESP System will be ON even if it was turned off previously. NOTE: The ESP Control System will make buzzing or clicking sounds when it is active. This is normal; the sound will stop when the ESP becomes inactive following a maneuver that caused the ESP activation. 21. SERV (Service) 4WD Indicator Light - If Equipped The "SERV 4WD Indicator Light" will turn on when the ignition key is turned to the ON position and it will stay on for 2 seconds. If the light stays on or turns on during driving, it means that the 4WD system is not functioning properly and that service is required. 22. Coolant Temperature Warning Light This light warns of an overheated engine condition. If the light turns on while driving, safely pull over and stop the vehicle. If the air conditioner is on, turn it off. Also, shift the transmission into "N" (Neutral) and idle the vehicle. If the temperature reading does not return to normal, turn the engine off immediately and call for service. (See page 384 for more information.) 4
