ENHANCED ACCIDENT RESPONSE SYSTEM (EARS)
This vehicle is equipped with an Enhanced Accident
Response System.Please refer to “Occupant Restraint Systems” in “Safety” for
further information on the Enhanced Accident Response
System (EARS) function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data Recorder (EDR).
The main purpose of an EDR is to record data that will assist
in understanding how a vehicle’s systems performed under
certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle.
Please refer to “Occupant Restraint Systems” in “Safety” for
further information on the Event Data Recorder (EDR).
WARNING!
• Do not use a chain for freeing a stuck vehicle. Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become disengaged, causing serious
injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for tow
truck hookup or highway towing. You could damage
your vehicle.

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 indi-
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).

Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a sched -
uled oil change is performed by someone other than your autho-
rized dealer, the message can be reset by referring to the steps
described under “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve 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.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
very low engine RPM’s. This type of vehicle use is consid
-
ered Severe Duty.

SERVICING AND MAINTENANCE 411
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for unusualwear or damage. Rotate at the first sign of irregular wear.
• Check the fluid levels of the coolant reservoir, brake master cylinder, power steering and automatic transmis -
sion (six-speed only), and fill as needed.
• Check function of all interior and exterior lights.Maintenance Plan
Required Maintenance
Refer to the maintenance plan on the following pages for
required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.

Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km) or 350 hours ofengine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
WARNING!
• You can be badly injured working on or around a motor vehicle. Do only service work for which you have the
knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
• Failure to properly inspect and maintain your vehicle could result in a component malfunction and effect
vehicle handling and performance. This could cause an
accident.

416 SERVICING AND MAINTENANCE
Checking Oil Level — Gas Engine
To assure proper lubrication of your vehicle's engine, 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. Always main-
tain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom of
the SAFE zone will result in a reading at the top of the safe
zone on these engines.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti -
freeze). 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 solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling 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.

SERVICING AND MAINTENANCE 417
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
DEALER SERVICE
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera -
tions in an expert manner. Service Manuals are available
which include detailed service information for your vehicle.
Refer to these Service Manuals before attempting any proce -
dure yourself.
NOTE:
Intentional tampering with emissions control systems may
void your warranty and could result in civil penalties being
assessed against you.
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. Refer to “Jump Starting Procedure” in “In Case
Of Emergency” for further information.
• 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.
CAUTION!
• It is essential when replacing the cables on the battery that the positive cable is attached to the positive post
and the negative cable is attached to the negative post.
Battery posts are marked positive (+) and negative (-)
and are identified on the battery case. Cable clamps
should be tight on the terminal posts and free of corro -
sion.
• If a “fast charger” is used while the battery is in the vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a “fast
charger” to provide starting voltage.
