inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. (See page 268 for more infor-
mation.)
6. 4LO Mode Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the 4 LO four–wheel drive mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. (See page 234 for more infor-
mation.) 7. Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
8. Malfunction Indicator Light This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.
Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
