This message may display along with the check engine
light on the instrument panel cluster if the vehicle’s
fuel cap is not tightened properly. SeeMalfunction
Indicator Lamp on page 3-36. Reinstall the fuel cap fully.
SeeFilling the Tank on page 6-9. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should turn
this light and message off.
TIRE LEARNING ACTIVE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the TPMS
is re-learning the tire positions on your vehicle. The tire
positions must be re-learned after rotating the tires
or after replacing a tire or sensor. SeeTire Inspection

Global Positioning System (GPS)
The navigation system determines the position of the
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road con guration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.
The GPS shows the current position of the vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When the vehicle is not
receiving signals from the satellites, a symbol appears
on the map screen. Refer toSymbols on page 4-16.
This system may not be available or interferences may
occur if any of the following are true:
Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the front dash of the vehicle.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s windshield.Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting interferes
with the system’s ability to receive GPS signals and
causes the system to malfunction. The window
might have to be replaced to correct the problem.
This would not be covered by the warranty.
For more information if the GPS is not functioning
properly, seeIf the System Needs Service on page 4-56
andProblems with Route Guidance on page 4-55.
Vehicle Positioning
At times, the position of the vehicle on the map may
be inaccurate due to one or more of the following
reasons:
Road system has changed.
Vehicle is driving on slippery road surfaces such as
in sand, gravel, and/or snow.
Vehicle is traveling on winding roads.
Vehicle is on a long straight road.
Vehicle is approaching a tall building or a large
vehicle.
Surface streets run parallel to a freeway.
Vehicle has just been transferred by a vehicle
carrier or a ferry.

It is very hot. When the temperature returns to
normal, the DVD should play.
You are driving on a very rough road. When the
road becomes smoother, the DVD should play.
The DVD is dirty, scratched, wet, or upside down.
The air is very humid. If so, wait about an hour and
try again.
There may have been a problem while burning
the DVD.
The label may be caught in the DVD player.
If the DVD is not playing correctly, for any other reason,
try a known good DVD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer/retailer.
Care of Your CDs and DVDs
If playing recorded media such as a CD or DVD, the
sound quality may be reduced due to CD or DVD quality,
the method of recording, the quality of the music that
has been recorded, recording speed, max media
recording speed, and the way the CD or DVD has been
handled. There may be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading and
ejecting. If these problems occur, check the bottomsurface of the CD or DVD. If the surface is damaged,
such as cracked, broken, or scratched, it will not
play properly. If the surface is soiled, see “Care of Your
CDs and DVDs” in the Index of the vehicle’s owner
manual.
If there is no apparent damage, try a known good
CD or DVD.
Notice:If a label is added to a CD or DVD, or more
than one CD or DVD is inserted into the slot at a
time, or an attempt is made to play scratched
or damaged CDs or DVDs, the player could be
damaged. While using the CD or DVD player, use
only CDs or DVDs in good condition without
any label, load one CD or DVD at a time, and keep
the player and the loading slot free of foreign
materials, liquids, and debris.
Do not add any label to a CD or DVD, it could get
caught in the player. If a CD or DVD is recorded on a
personal computer and a description label is needed, try
labeling the top of the recorded CD or DVD with a
soft marker.

It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 5-29
Traction Control Operation
The traction control system is part of the StabiliTrak
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
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. See
Cruise Control on page 3-10
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.

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to the vehicle’s
three control systems. In the braking skid, the wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels
to spin.
Remember: Any traction control system helps avoid only
the acceleration skid. If the traction control system is
off, then an acceleration skid is best handled by easing
your foot off the accelerator pedal.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including reducing vehicle speed by shifting to a lower
gear. Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until the
vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
Off-Road Driving
Vehicles with 22-inch tire/wheel assemblies should not
be driven off-road except on a level, solid surface.
Many of the vehicle design features that help make the
vehicle more responsive on paved roads during poor
weather conditions also help make it better suited
for off-road use than conventional passenger vehicles.
The vehicle does not have features usually thought to be
necessary for extended or severe off-road use such
as special underbody shielding and transfer case
low gear range.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Always wear your safety belt and observe safe driving
speeds, especially on rough terrain.
5-12

Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired — by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because headlamps can only light up
so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns or
curves.No one can see as well at night as in the daytime. But,
as we get older, these differences increase. A
50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or owing water.
{CAUTION:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of the
vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal until
the brakes work normally.
CAUTION: (Continued)
