Electronic Sway Bar Disconnect — If
Equipped
Your vehicle may be equipped with an elec-
tronic disconnecting stabilizer/sway bar. This
system allows greater front suspension travel
in off-road situations.This system is controlled by the SWAY BAR
switch located on the instrument panel (to
the left of the steering column).
Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illumi-
nate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation con-ditions are not met. The stabilizer/sway bar
should remain in on-road mode during nor-
mal driving conditions.
WARNING!
Do not disconnect the stabilizer bar and
drive on hardsurfaced roads or at speeds
above 18 mph (29 km/h); you may lose
control of the vehicle, which could result
in serious injury. The front stabilizer bar
enhances vehicle stability and is neces-
sary for maintaining control of the vehicle.
The system monitors vehicle speed and
will attempt to reconnect the stabilizer bar
at speeds over 18 mph (29 km/h). This is
indicated by a flashing or solid “Sway Bar
Indicator Light.” Once vehicle speed is
reduced below 14 mph (22 km/h), the
system will once again attempt to return to
off-road mode.
To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR
switch to obtain the off-road position. Refer
to “Four-Wheel Drive Operation” in this sec-

atmospheric conditions change to allow the
condensation to change back into a vapor.
Turning the lamps on will usually accelerate
the clearing process.

SCHEDULED SERVICING
Scheduled Servicing — Gasoline Engine
The scheduled services listed in this manual
must be done at the times or mileages speci-
fied to protect your vehicle warranty and
ensure the best vehicle performance and re-
liability. More frequent maintenance may be
needed for vehicles in severe operating con-
ditions, such as dusty areas and very short
trip driving. Inspection and service should
also be done anytime a malfunction is sus-
pected.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
On non-instrument cluster display equipped
vehicles, “CHANgE OIL” will flash in the
instrument cluster odometer and a single
chime will sound, indicating that an oil
change is necessary.The oil change indicator message will illumi-
nate approximately 7,000 miles
(11,200 km) after the most recent oil change
was performed. Have your vehicle serviced as
soon as possible, within 500 miles (800 km).
However, an earlier oil change at 4,500 miles
(7,500 km) may be required if the vehicle is
operated under “Severe Duty Conditions”
later in this section.
NOTE:
• The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been
6 months since your last oil change even if
the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change
intervals exceed 7,500 miles (12,000 km)
or 6 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.Once A Month Or Before A Long Trip
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
• 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.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of coolant reservoir,
automatic transmission, brake master cyl-
inder and power steering and fill as needed.
• Check all lights and other electrical items
for correct operation.

WARNING!
doubt about your ability to perform a
service job, take your vehicle to a com-
petent 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.
Severe Duty Conditions
†† Change the engine oil and engine oil filter
at every 4500 miles (7,500 km) or 6 months
if using your vehicle under any of the follow-
ing severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.
• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — Diesel Engine
At Each Stop for Fuel
• Check the engine oil level about five min-
utes after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent, add
as required.
Once a Month
• 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.
• Inspect the battery; clean and tighten the
terminals as required.
• Check the fluid levels of engine coolant/
antifreeze deaeration bottle, and brake
master cylinder, add as needed.
• Check all lights and all other electrical
items for correct operation.At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect brake hoses.
• Check the engine coolant/antifreeze level,
hoses, and clamps.
• Inspect engine accessory drive belts. Re-
place as necessary.
• Inspect for the presence of water in the fuel
filter/water separator unit.
Inspection and service should be performed
anytime a malfunction is observed or sus-
pected. Retain all receipts.

or more, run the air conditioning system at
idle for about five minutes in the fresh air
and high blower setting. This will ensure
adequate system lubrication to minimize
the possibility of compressor damage when
the system is started again.
BODYWORK
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic head-
lights and fog lights that are lighter and less
susceptible to stone breakage than glass
headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures
must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid wip-
ing with a dry cloth. To remove road dirt, wash
with a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate-
rial to clean the lenses.
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash
your vehicle in the shade using a mild car
wash soap, and rinse the panels completely
with clear water.
• Use a high quality cleaner wax remove road
film, stains and to protect your paint finish.
Take care never to scratch the paint.
• Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin
out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder that will scratch metal and
painted surfaces.
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
Special Care
• If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar-
riage at least once a month.
• It is important that the drain holes in the
lower edges of the doors, rocker panels, and
trunk be kept clear and open.
• If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the re-
sponsibility of the owner.
• If your vehicle is damaged due to a collision
or similar cause that destroys the paint and
protective coating, have your vehicle re-
paired as soon as possible. The cost of such
repairs is considered the responsibility of
the owner.
• If you carry special cargo such as chemi-
cals, fertilizers, de-icer salt, etc., be sure
that such materials are well packaged and
sealed.
• If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
