Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
Instrument Panel 3-33

vehicle from a distance, if equipped,
you may not see the system
check. Then, after several more
seconds, the status indicator
will light either ON or OFF, or either
the on or off symbol to let you
know the status of the right front
passenger frontal airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right front
passenger frontal airbag is enabled
(may inate).
If the word OFF or the off symbol is
lit on the passenger airbag status
indicator, it means that the
passenger sensing system has
turned off the right front passenger
frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if
there are no lights at all, there may
be a problem with the lights or
the passenger sensing system.
See your dealer/retailer for service.{CAUTION
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away.
SeeAirbag Readiness Light on
page 3-36for more information,
including important safety
information.
Charging System Light
The charging system light comes on
briey when the ignition is turned
on, but the engine is not running,
as a check to show the light is
working. It should go out when the
engine is started.If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer/retailer. Driving while this light
is on could drain the battery.
When this light comes on, the Driver
Information Center (DIC) will also
display the SERVICE BATTERY
CHARGING SYSTEM message.
SeeDIC Warnings and Messages
on page 3-56for more information.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Instrument Panel 3-37

The traction control system is
enabled automatically when the
vehicle is started. It will activate and
the StabiliTrak light will ash if it
senses that any of the wheels are
spinning or beginning to lose traction
while driving. If traction control is
turned off, only the brake-traction
control portion of traction control
will work. The engine speed
management will be disabled. In this
mode, engine power is not reduced
automatically and the driven
wheels can spin more freely. This
can cause the brake-traction control
to activate constantly.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak, ABS and
brake warning lights and any
relevant DIC messages are
displayed, the transfer case could
be damaged. The repairs would
not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights
and messages are displayed.The traction control system may
activate on dry or rough roads
or under conditions such as heavy
acceleration while turning or
abrupt upshifts/downshifts of the
transmission. When this happens, a
reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when
the system activates, the StabiliTrak
light will ash and cruise control
will automatically disengage. Cruise
control may be reengaged when
road conditions allow. SeeCruise
Control on page 3-9.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
If the problem does not clear itself
after restarting the vehicle, see your
dealer/retailer for service.All-Wheel Drive (AWD)
System
If the vehicle has this feature,
engine power is sent to all four
wheels when extra traction is
needed. This is like four-wheel drive,
but there is no separate lever or
switch to engage or disengage the
axle. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire
on the AWD equipped vehicle,
the AWD system automatically
detects the presence of the compact
spare and the AWD is disabled.
To restore the AWD operation and
prevent excessive wear on the
AWD system, replace the compact
spare with a full-size tire as
soon as possible. SeeCompact
Spare Tire on page 5-81for more
information.
