IN CASE OF EMERGENCY229
IF YOUR ENGINE OVERHEATS
In any of the following situations, 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, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending 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 — 8 – SPEED
TRANSMISSION 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.

230IN CASE OF EMERGENCY
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.
Follow these steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Remove the console storage bin to access
the Manual Park Release lever.

Console Storage Bin

3. Using a small screwdriver or similar tool, fish the tether strap up through the opening
in the console base.
4. Press and maintain firm pressure on the brake pedal. 5. Insert the screwdriver into the slot in the
center of the lever, and disengage the lever
locking tab by pushing it to the right.

Engaging The Lever

6. Pull the tether strap to rotate the lever up and rearward until it locks in place in the
vertical position. The vehicle is now out of
PARK and can be moved. Release the
parking brake only when the vehicle is
securely connected to a tow vehicle. To Reset The Manual Park Release:

1. Push the latch (at the base of the lever, on
the rear side) rearward (away from the
lever) to unlatch the lever.

Disengaging The Lever

2. Rotate the Manual Park Release lever forward and down, to its original position,
until the locking tab snaps into place to
secure the lever.
3. Pull up gently on the tether strap to confirm that the lever is locked in its stowed
position.
4. Tuck the tether strap into the base of the console. Reinstall the console storage bin.

IN CASE OF EMERGENCY233
REAR-WHEEL DRIVE (RWD) MODELS
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed. If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
flat towed (with all four wheels on the ground)
under the following conditions:
The transmission must be in NEUTRAL. Refer
to "Manual Park Release" in this section for
instructions on shifting the automatic trans
-
mission to NEUTRAL when the engine is off.
The towing distance must not exceed
30 miles (48 km).
The towing speed must not exceed 30 mph
(48 km/h).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
then the only acceptable method of towing is
with a flatbed truck.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the
Enhanced Accident Response System (EARS)
function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is
to record data that will assist in understanding
how a vehicle’s systems performed under
certain crash or near crash-like situations, such
as an air bag deployment or hitting a road
obstacle.
Please refer to “Occupant Restraint Systems” in
“Safety” for further information on the Event
Data Recorder (EDR).
CAUTION!
Do not use sling type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flat bed
truck, do not attach to front or rear suspen -
sion components. Damage to your vehicle
may result from improper towing.
The manufacturer does not recommend
towing this vehicle using a tow dolly.
Vehicle damage may occur.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine and/
or transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.

266SERVICING AND MAINTENANCE
(Continued)
BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only brake fluid that has been
recommended by the manufacturer, and has
been kept in a tightly closed container to avoid
contamination from foreign matter or moisture.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
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. You would not have your full braking
capacity in an emergency.
WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri
-
cants” in “Technical Specifications” for
further information. 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 reser -
voir cap secured at all times. Brake fluid in
a 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.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
