22. Cargo Light
The Cargo Lamp light will illuminate when the
Cargo Lamp is activated by pressing the Cargo
Light Button on the headlight switch.
23. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the 4WD
mode is engaged for either the manual or electric shift
4WD systems. The SERV 4WD indicator monitors the
electric shift 4WD system. If the SERV 4WD light stays on
or comes on during driving, it means that the 4WD system
is not functioning properly and that service is required.
24. ESP/BAS Warning Lamp – If Equipped
The lamp indicates a problem with one or more
of the functions of ESP. The yellow "ESP/BAS
Warning Lamp" in the instrument cluster
comes on when the ignition switch is turned to
the "ON" position as a bulb check. It should go out with
the engine running. If the "ESP/BAS Warning Lamp"
comes on continuously with the engine running, a mal-
function has been detected in the ESP system. If this light
remains on after 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. NOTE: • The ESP/BAS Warning Lamp come
on momentarily each time the ignition switch is turned
ON. • The ESP Control System will make buzzing or
clicking sounds when it is actively operating.
25. Tire Pressure Monitoring Telltale Light — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
