Daytime running lamps (DRL) (if equipped)
Turns the headlamps on with a reduced output.
In order for the DRLs to function:
•the ignition must be in the on position and
•the headlamp control is in the
, parking lamp or autolamp position.
WARNING:Always remember to turn on your headlamps at
dusk or during inclement weather. The Daytime Running Lamp
(DRL) system does not activate the tail lamps and generally may not
provide adequate lighting during these conditions. Failure to activate
your headlamps under these conditions may result in a collision.
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel when exterior
lights are on.
•Rotate the thumbwheel from left
to right to brighten the
instrument panel.
•Rotate the thumbwheel from right
to left to dim the instrument
panel.
•Rotate fully to the right (past detent) to turn on interior lamps.
•Rotate to the left position (past detent) to turn off the interior lamps
and to disable the illuminated entry feature. When the control is in the
far left position, it acts as a dome lamp defeat/override.
Note:If the battery is disconnected, discharged, or a new battery is
installed, the dimmer switch requires re-calibration. Rotate the dimmer
switch from the full dim position to the full dome/on position to reset.
This will ensure that your displays are visible under all lighting
conditions.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, the alignment of your headlamps
should be checked by your authorized dealer.

WARNING:If your vehicle is stuck in snow, mud, sand, etc.,do
notrapidly spin the tires; spinning the tires can tear the tire and
cause an explosion. A tire can explode in as little as three to five
seconds.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front wheel drive (FWD) vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance informationthat comes with your vehicle) will
help your tires wear more evenly, providing better tire performance and
longer tire life.

vehicles/Four Wheel Drive
(4WD)/ All Wheel Drive (AWD)
vehicles (front tires at top of

Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, check tire pressure and adjust to
the recommended inflation pressure.
WARNING:If the tire label shows different tire pressures for
the front and rear tires and the vehicle is equipped with TPMS
(tire pressure monitoring system), then the TPMS sensors need to be
reset after tire rotation. If the system is not reset, it may not provide a
low tire pressure warning when necessary. See the TPMS reset
procedure in this chapter.

•Some noise is normal during operation. If the noise is excessive, check
for a low power steering fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by a low power
steering fluid level. Check for a low power steering fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering fluid reservoir above the MAX mark on
the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Limited-slip axle functions like a standard rear axle. The axle may
exhibit a slight noise or vibration in tight turns with low vehicle speed.
This is normal behavior and indicates the axle is working.
Electronic locking differential (ELD) axle (if equipped)
This axle provides added traction on slippery and/or off road surfaces,
particularly when one wheel is on a poor traction surface. In normal
driving conditions the rear axle function as a standard axle. The ELD
may be locked or unlocked by the vehicle operator. Refer toFour-wheel
drive (4WD) operationsection in this chapter for further detail on ELD
function and usage. When the axle is unlocked it will function like a
standard rear axle. When the axle is locked it will not allow the rear
wheels to rotate at different speeds when turning. The ELD axle is not
recommended for use on good traction surfaces such as dry pavement.
Doing so may result in abnormal driving behavior while cornering and
excessive tire wear.

Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA fuel economy estimates
Every new vehicle should have a window sticker containing EPA fuel
economy estimates. Contact your authorized dealer if the window sticker
is not supplied with your vehicle. The EPA fuel economy estimates
should be your guide for the fuel economy comparisons with other
vehicles. Your fuel economy may vary depending upon the method of
operation and conditions.
