Trunk Open Warning Light
This indicator will illuminate when the
trunk is open and not fully closed.
NOTE:
If the vehicle is moving, there will also be a single
c h
ime.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
li
ght turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
c or

rected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to
indicate the engine oil temperature is
h i
gh. If the light turns on while driving,
stop the vehicle and shut off the engine
as soon as possible. Wait for oil temperature to
return to normal levels.
Transmission Temperature Warning Light

illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission

eventually cause severe transmission damage
or transmission failure.

IN CASE OF EMERGENCY 187
PREPARATIONS FOR JUMP START
The battery is stored under an access cover in the
trunk. Remote battery posts are located on the
right side of the engine compartment for jump
starting.

Jump Starting Locations

NOTE:
The remote battery posts are viewed by standing
on
the right side of the vehicle looking over the
fender. The positive battery post may be covered
with a protective cap. Lift up on the cap to gain
access to the positive battery post. Do not jump off
fuses. Only jump directly off positive post which
has a positive (+) symbol on or around the post.
Jump Starting Posts

See below steps to prepare for jump starting:

1. Apply the parking brake, shift the automatic t
ransmission into PARK and cycle the ignition
to OFF.

2. T urn off the heater, radio, and all electrical
a
ccessories.
3. If using another vehicle to jump start the b
attery, park the vehicle within the jumper
cables reach, set the parking brake, and make
sure the ignition is OFF.
Remote Positive (+) Post
Remote Negative (-) Post

Remote Negative (-) Post
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.7

190 IN CASE OF EMERGENCY
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
th

e potential for overheating by taking the
appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
e n
gine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down an
i m
pending 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.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (such as a
depleted battery), a Manual Park Release is
available.
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.

CAUTION!

Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and call
for service.

WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver's seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

SERVICING AND MAINTENANCE 209
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.
To minimize the possibility of catalytic converter
da

mage:
Do not shut off the engine or interrupt the igni -
tion when the transmission is in gear and the
v e
hicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug wires
disconnected or removed, such as when diag -
nostic testing, or for prolonged periods during
ve
ry rough idle or malfunctioning operating
conditions.
NOTE:
Your vehicle’s exhaust system may be equipped
w i
th an Electronic Exhaust Valve (EEV) system, if
the exhaust system is replaced with aftermarket
products a Malfunction Indicator Lamp (MIL) will
illuminate.
COOLING SYSTEM
Coolant Checks
Check engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather,
w h
ere applicable). If the engine coolant is dirty, the
system should be drained, flushed, and refilled
with fresh Organic Additive Technology (OAT)
coolant (conforming to MS.90032) by an authorized dealer. Check the front of the radiator
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.
Check the coolant recovery bottle tubing for brittle
r
u

bber, cracking, tears, cuts, and tightness of the
connection at the bottle and radiator. Inspect the
entire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant
p r
operly. Failure to fill these systems properly
could lead to severe internal engine damage. If any
coolant is needed to be added to the system
please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or
c on

tains visible sediment, have an authorized
dealer clean and flush with Organic Additive
Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Ú page 195.
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 on

trolled and can start at any time the igni -
tion is in the ON mode.
