NOTE:After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the
engine. After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.

IN CASE OF EMERGENCY335
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, follow the discon -
necting procedure.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper
cable from the engine ground of the vehicle
with the discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
vehicle with the discharged battery, and
reinstall the protective cap over the positive
(+) post. If frequent jump starting is required to start your
vehicle you should have the battery and charging
system inspected at an authorized dealer.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
Strong smell of coolant
White smoke coming from engine or exhaust
Coolant bottle coolant has bubbles present
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans
-
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
CAUTION!
Do not connect jumper cable to any of the fuses
on the positive battery terminal. The resulting
electrical current will blow the fuse.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.).
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.

360SERVICING AND MAINTENANCE
When inspecting accessory drive belts, small
cracks that run across ribbed surface of belt from
rib to rib, are considered normal. These are not a
reason to replace belt. However, cracks running
along a rib (not across) are not normal. Any belt
with cracks running along a rib must be replaced.
Also have the belt replaced if it has excessive wear,
frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two
ribs)
Belt slips
Groove jumping (belt does not maintain correct
position on pulley)
Belt broken (identify and correct problem before
new belt is installed)
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
DRAINING FUEL/WATER SEPARATOR
F
ILTER
There are two fuel filter assemblies. One is located
on the driver's side of the engine. The best access
to this water drain valve is from under the hood.
The second one is on the under body, located in
front of the rear axle above the drive shaft on
pick-up models. The second filter location is on the
frame behind the front axle. The best access to this
water drain valve is from under the vehicle. If water is detected in the water separator while the
engine is running, or while the ignition switch is in
the ON position, the Water In Fuel Indicator Light
will illuminate and an audible chime will be heard
five times. At this point you should stop the engine
and drain the water from both of the filters.
If the Water In Fuel Indicator Light comes on and a
single chime is heard while you are driving, or with
the ignition switch in the ON position, there may be
a problem with your water separator wiring or
sensor. See an authorized dealer for service.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
CAUTION!
If the Water In Fuel Indicator Light remains on,
DO NOT START the engine before you drain water
from the fuel filters to avoid engine damage.

4. Slide the wiper blade up into the hook on the
wiper arm until it is latched (engagement will
be accompanied by an audible click). Fold
down the latch release tab and snap it into its
locked position.
5. Gently lower the wiper blade onto the glass.
EXHAUST SYSTEM
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected
inside the vehicle; or when the underside or rear of
the vehicle is damaged; have an authorized
technician 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, have the exhaust system inspected each
time the vehicle is raised for lubrication or oil
change. Replace as required. Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon
-
scious and can eventually poison you
Ú page 324.
A hot exhaust system can start a fire if you
park over materials that can burn. Such mate -
rials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.
CAUTION!

significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
TEMPERATURE GRADES
The Temperature grades are A (the
highest), B, and C, representing the tire's
resistance to the generation of heat and
its ability to dissipate heat, when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance, which all
passenger vehicle tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel, than the
minimum required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than three
weeks, we recommend that you take the following
steps to minimize the drain on your vehicle's
battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks 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 lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
Vehicle body care requirements vary according to
geographic locations and usage. Chemicals that
make roads passable in snow and ice and those
that are sprayed on trees and road surfaces during
other seasons are highly corrosive to the metal in
your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold
weather and other extreme conditions will have an
adverse effect on paint, metal trim, and underbody
protection.
WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
