218IN CASE OF EMERGENCY
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 If 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 highways — slow down.
 In city traffic — while stopped, place the transmission 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 supple -
ment 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, you can use the following
procedure to temporarily move the gear selector:

1. First turn the engine OFF.

2. Apply the parking brake.
3. Grab the boot material of the gear selector and pull up to carefully separate the gear selector bezel and
boot assembly from the center console.

Gear Selector Bezel

4. Press and maintain firm pressure on the brake pedal.
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.

5. Locate the gear selector override access (at the right
rear corner of the gear selector assembly). Using a
small screwdriver or similar tool, push and hold the
override release lever down.

Gear Selector Override Access Location

6. Move the gear selector to the NEUTRAL (N) position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Push and hold the button on the gear selector.
Then shift back and forth between DRIVE (D) and
REVERSE (R) while gently pressing the accelerator.
NOTE:Shifts between DRIVE (D) and REVERSE (R) can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL (N) for
more than two seconds, you must press the brake pedal
to engage DRIVE (D) or REVERSE (R).
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE:Push the ESC OFF button (if necessary), to place the Elec -
tronic Stability Control (ESC) system in the “Off” mode,
before rocking the vehicle
Úpage 156. Once the vehicle
has been freed, push the ESC OFF button again to restore
“ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping when you
are stuck and do not let anyone near a spinning wheel,
no matter what the speed.
CAUTION!
 Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL for
at least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
 When “rocking” a stuck vehicle by shifting between
DRIVE gear and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.
 Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis -
sion shifting occurring).

SERVICING AND MAINTENANCE233
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 specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter damage:
Do not interrupt the ignition when the transmission 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 components
disconnected or removed, such as during diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating 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.
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).
Refer to the Maintenance Plan for the proper
maintenance intervals
Úpage 224.
Selection Of Coolant
For further information Úpage 269.
NOTE:
Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro -
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is introduced
into the cooling system in an emergency, the cooling
system will need to be drained, flushed, and refilled
with fresh OAT coolant (conforming to MS.90032), by
an authorized 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 plug the radiator.

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 radiator 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, discon -
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
Safety
 Fuel Economy
 Tread Wear
 Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the stability of
the vehicle and can produce a feeling of sluggish response
or over responsiveness in the steering.
NOTE:

Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
 Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver's side B-pillar or rear edge of the driver's side door.
At least once a month:
 Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual judg -
ment when determining proper inflation. Tires may look
properly inflated even when they are underinflated.
 Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
WARNING!
 Improperly inflated tires are dangerous and can
cause collisions.
 Underinflation increases tire flexing and can result in
overheating and tire failure.
 Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause
damage that result in tire failure.
 Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
 Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the
right or left.
 Always drive with each tire inflated to the recom -
mended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.
