affect your vehicle’s handling. If you ever replace a wheel,
make sure that the wheel’s specifications match those of
the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Fail-
ure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load

index could result in tire overloading and failure.
You could lose control and have a collision.
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS (TRACTION DEVICES)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.
• Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer
• Install on Front Tires
• Due to limited clearance, a 185/55R15 tire with a
Security Chain Company (SCC) Super Z6 low profile
traction device or equivalent is recommended

STARTING AND OPERATING 207

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. Then, shift back and forth between DRIVE
and REVERSE while gently pressing the accelerator.
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning the
wheels.
NOTE:Push the ESC Off switch, to place the Elec-
tronic Stability Control (ESC) system in Partial Off
mode, before rocking the vehicle. Refer to “Electronic
Brake Control” in “Starting And Operating” for further
information. Once the vehicle has been freed, push the
ESC Off switch again to restore ESC Onmode.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated 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
(Continued)
WARNING! (Continued)
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Spinning the wheels too fast may lead to trans-
mission overheating and failure. It can also dam-
age the tires. Do not spin the wheels above
30 mph (48 km/h) while in gear.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
Release. Activating the Manual Park Release will

WARNING!(Continued)
allow your vehicle to roll away if it is not secured
by the parking brake or other means. Activating the
Manual Park Release on an unsecured vehicle could
lead to serious injury or death for those in or
around the vehicle.
In order to move the vehicle in cases where the trans-
mission will not shift out of PARK (such as a dead
battery), a Manual Park Release is available. If a dead 12
volt battery is the cause of the condition refer to “Jump
Start Procedure — 12 Volt Battery” before performing
the Manual Park Release.
To perform the Manual Park Release follow these steps:
1. To prevent the vehicle from rolling unintentionally, firmly apply the parking brake.
2. If possible, raise the front driver’s side of the vehicle to provide access to the transmission.
3. Working from underneath the vehicle, remove the black rubber plug from the front of the Park module
(a black canister mounted on the front of the trans-
mission). 4. Using a T25 driver bit, rotate the Manual Park
Release shaft (located just behind the rubber plug)
clockwise, at least 20 turns, to release the Park
mechanism. The vehicle is now out of PARK and can
be moved.
5. Reinstall the rubber plug.
6. Release the parking brake only when a driver is in the vehicle, or the vehicle is secured by other means.
The Manual Park Release will be reset automatically
once the vehicle is restarted.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CYBERSECURITY
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should
connect equipment to the OBD II connection port
in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information. For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
REPLACEMENT PARTS
Use of genuine parts for normal/scheduled mainte-
nance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by
the use of parts which are not quality-equivalent to
genuine parts for maintenance and repairs will not be
covered by the manufacturer ’s warranty.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
240 MAINTAINING YOUR VEHICLE

NOTE:
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer ’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” 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 cylin-
der 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 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 vehicle 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 contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
Appearance Care And Protection From
Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
