190STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Care should be taken when attempting to climb steep hills
or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diagonally
across the hill.
When driving over sand, mud, and other soft terrain, shift
to low gear and drive steadily. Apply the accelerator slowly
to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required. 
Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
CAUTION!
Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
 Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
 Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
 Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, transmis -
sion, axle, etc.) for signs of contamination (i.e., fluid
that is milky or foamy in appearance) after driving
through standing water. Do not continue to operate
the vehicle if any fluid appears contaminated, as this
may result in further damage. Such damage is not
covered by the New Vehicle Limited Warranty.
 Getting water inside your vehicle’s engine can cause
it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered
by the New Vehicle Limited Warranty.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.

Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display
Úpage 98.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or
350 hours of engine run time, whichever comes first.
The 350 hours of engine run or idle time is generally only
a concern for fleet customers.
Once A Month Or Before A Long Trip:

Check engine oil level.
 Check windshield washer fluid level.
 Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular
wear, even if it occurs before the oil indicator system
turns on.
 Check the fluid levels of the coolant reservoir, brake
master cylinder, and fill as needed.
 Check function of all interior and exterior lights.

340SERVICING AND MAINTENANCE
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
 Crosshatched zone marked SAFE.
 Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
 Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1.0 L) of oil when the reading is at the low end
of the dipstick range will raise the oil level to the high end
of the range marking.
ADDING WASHER FLUID
The fluid reservoir is located under the hood and the fluid
level should be checked at regular intervals. Fill the
reservoir with windshield washer solvent only (not radiator
antifreeze). When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or towel and wipe
the wiper blades clean. This will help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the
container, aids cleaning action, reduces the freezing point
to avoid line clogging, and is not harmful to paint or trim.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, and periodic
maintenance is not required.
CAUTION!
Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage
your engine.
WARNING!
Commercially available windshield washer solvents are
flammable. They could ignite and burn you. Care must
be exercised when filling or working around the washer
solution.
WARNING!
Battery fluid is a corrosive acid solution and can burn
or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with large
amounts of water
Úpage 325.
 Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Do not use a
booster battery or any other booster source with an
output greater than 12 Volts. Do not allow cable
clamps to touch each other.
 Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands after
handling.
