3. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cable’s reach, set the parking brake and make
sure the ignition is OFF.JUMP STARTING PROCEDURE
Connecting The Jumper Cables

1. Connect the positive
(+) en
d of the jumper
cable to the positive (+)
post of the discharged
vehicle.

2. Connect the opposite end of the positive (+)
ju m

per cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) en
d of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
ju m

per cable to a good engine ground. A
“ground” is an exposed metallic/unpainted
part of the engine, frame or chassis, such as an accessory bracket or large bolt. The ground
must be away from the battery and the fuel
injection system.

Suitable Engine Ground

5. S tart the engine in the vehicle that has the
booste r

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, remove the jumper cable
s in the reverse sequence.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery. The
res u
lting electrical spark could cause the battery
to explode and could result in personal injury.7

5. Remove funnel from filler pipe, clean off prior
to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the pot
ential for overheating your engine by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, put transmission
in NEUTRAL (N), but do not increase engine idle
speed.
NOTE:
There are steps that you can take to slow down an
impen d
ing overheat condition:
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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position, follow
the steps below:
NOTE:
A depleted battery will prevent the Electric Park
Brake
to be applied.

1. Turn the engine OFF.

2. App

ly the Electric Park Brake.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
“H”, pull over and stop the vehicle. Idle the vehi -
cle with the air conditioner turned off until the
pointe r

drops back into the normal range. If the
pointer remains on the “H” and you hear contin -
uous chimes, turn the engine off immediately
and c a

ll for service.
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 cool -
ant bottle is hot.

SERVICING AND MAINTENANCE 299
(Continued)
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
syste m
s can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfu n

ctioning 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.
To minimize the possibility of catalytic converter
damag
e

:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagn os
tic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather,
where
applicable). If the engine coolant is dirty or
rusty in appearance, the system should be
drained, flushed and refilled with fresh engine
coolant. Check the front of the A/C condenser for
any accumulation of bugs, leaves, etc. If dirty,
clean by gently spraying water from a garden hose
vertically down the face of the condenser.
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 operation
of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in
possible damage to the converter and vehicle.

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 open a
cooling system pressure cap when the radi -
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
c ontroll

ed and can start at any time the igni -
tion is in the ON mode.
WARNING!

302 SERVICING AND MAINTENANCE
(Continued)
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
O ther

designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 287.
Brake Master Cylinder
The fluid level in the master cylinder should be
checked when performing under hood services, or
immediately if the Brake Warning Light is on.
Be sure to clean the top of the master cylinder area
before

removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. Fluid level
can be expected to fall as the brake pads wear. The
brake fluid level should be checked when the pads
are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid
Ú page 345.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. Riding
the brakes may also reduce braking capacity in
an emergency.WARNING!
Use only manufacturer’s recommended brake
fluid
Ú page 345. Using the wrong type of
brake fluid can severely damage your brake
system
and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake
fluids may damage the clutch system resulting in
loss of clutch function and the ability to shift the
transmission.
WARNING!
