IN CASE OF EMERGENCY345
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cable’s reach, apply the parking brake and
make sure the ignition is OFF.
JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
Connecting The Jumper Cables

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

2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery. 3. Connect the negative
(-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper 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.

Jump Starting Label

WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
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 resulting
electrical spark could cause the battery to
explode and could result in personal injury.

348IN CASE OF EMERGENCY
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.
MANUAL PARK RELEASE
In order to move the vehicle in cases where the
transmission will not shift out of Park (P) (such as
a depleted battery), a Manual Park Release is
available. See the following steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Using a small screwdriver or similar tool,
remove the manual park release cover located
in front of the gear selector, to access the
release tether strap.

Manual Park Release Cover

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 “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 the “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 MAINTENANCE377
COOLING SYSTEM
Coolant Checks
Check the 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 Organic
Additive Technology (OAT) coolant (conforming to MS.90032) by an authorized dealer. Check the
front of the A/C condenser (if equipped) or 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 A/C condenser (if
equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the coolant recovery 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
Some vehicles require special tools to add coolant
properly. 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
contains visible sediment, have an authorized
dealer clean and flush with OAT coolant
(conforming to MS.90032).
For the proper maintenance intervals see
Ú
page 354 for gas engines or Ú page 358 for
diesel engines.
Selection Of Coolant
For further information Ú page 424.
NOTE:
Mixing of engine coolant (antifreeze), other than
specified Organic Additive Technology (OAT)
engine coolant, may result in engine damage
and may decrease corrosion protection. OAT
engine coolant is different and should not be
mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is
introduced into the cooling system in an emer -
gency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by an autho -
rized dealer as soon as possible.
Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust
inhibitors or anti-rust products, as they may not
be compatible with the radiator engine coolant
and may clog the radiator.
This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not
recommended.
Some vehicles require special tools to add
coolant properly. 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.
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 position. The fan is tempera -
ture controlled and can start at any time the
ignition is in the ON position.
