Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off. Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine could
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.

If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Remove and Reinstall the Battery
To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty. 4. Disconnect the negative battery cable
terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery, make
sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
Note: After cleaning or replacing the battery,
make sure you reinstall the battery cover or
shield.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Windows
(page 130).
• Clock Settings.
• Pre-set radio stations.
• Steering Angle Sensor. Note:
To calibrate the steering angle sensor,
drive the vehicle above
30 mph (50 km/h)
for a minimum of 1.2 mi (2 km). Make sure to
drive straight ahead for a minimum of 30
seconds. Several vehicle functions are
disabled and a warning light could appear
until the sensor is calibrated.
Battery Management System
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some of the following features:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active.

WAXING
Wax the high-gloss painted surface of your
prewashed vehicle once or twice a year.
We recommend that you only use an
approved quality wax that does not contain
abrasives. For additional information and
assistance, we recommend that you contact
an authorized dealer.
When washing and waxing, park your vehicle
in a shaded area out of direct sunlight.
Note:
Avoid waxing unpainted or low-gloss
black colored parts, they discolor over time.
CLEANING THE INTERIOR
Cleaning the Instrument Panel WARNING: Do not use chemical
solvents or strong detergents when
cleaning the steering wheel or instrument
panel to avoid contamination of the airbag
system. We recommend that you only clean the
instrument panel and cluster lens with a
damp soft cloth. Dry the area with a clean,
soft cloth.
For additional information and assistance,
we recommend that you contact an
authorized dealer.
Note:
Avoid cleaners or polishes that
increase the gloss of the upper portion of
the instrument panel. The dull finish in this
area helps protect you from undesirable
windshield reflection.
Cleaning Plastic
We recommend that you only use a mild
soap and water solution on a soft cloth. Dry
the area with a clean, soft cloth.
Cleaning Displays and Screens
We recommend that you only use a
microfiber cloth in a circular motion to clean
off the fingerprint or dust. If dirt or fingerprints are still on the screen,
apply a small amount of alcohol to the cloth
and try to clean it again.
Note:
Do not pour or spray alcohol onto the
touchscreen.
Note: Do not use detergent or any type of
solvent to clean the touchscreen.
Cleaning Leather and Vinyl
We recommend that you only clean the
leather and vinyl surfaces in the following
way:
1. Remove dust and loose dirt with a vacuum cleaner.
2. Wipe the surface with a soft, damp cloth
and a mild soap and water solution. Dry
the area with a clean, soft cloth.
3. Make sure the leather is dry, then apply a small amount of conditioner to a clean,

USING SNOW CHAINS
WARNING: Do not exceed 30 mph
(50 km/h). Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel can
affect the safety and performance of your
vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure. Follow the recommended tire inflation pressures
found on the Safety Compliance
Certification label, or the Tire Label on the
B-Pillar or the edge of the driver door.
Failure to follow this instruction could result
in loss of vehicle control, vehicle rollover,
or personal injury or death.
Only use snow chains on the front wheels.
Install snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire size:
• 235/60R18 all season tires.
•Only use ultra low profile snow chains
that are 10 mm or less.
We recommend you use steel wheels of the
same size and specification if snow chains
are required because chains may chip
aluminum wheels.
Follow these guidelines when using snow
tires and traction devices: •
If possible, avoid fully loading your
vehicle.
• Purchase snow chains from a
manufacturer that clearly labels body to
tire dimension restrictions.
• When driving with snow chains do not
exceed
30 mph (50 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Drive cautiously. If you hear the snow
chains rub or bang against the vehicle,
stop and tighten them. If this does not
work, remove the snow chains to prevent
vehicle damage.
• Remove the snow chains when they are
no longer needed. Do not use snow
chains on dry roads.
• If a temporary spare wheel is mounted
on your vehicle, do not use snow chains
on the axle with the temporary spare
wheel.
• Use snow chains that fit against the
sidewall of the tire to prevent the chains
from touching the wheel rims or
suspension.

compound that will effectively seal most
punctures. This kit will provide a temporary
tire repair allowing you to drive your vehicle
up to 120 mi (200 km) at a maximum speed
of 50 mph (80 km/h) to reach a tire service
location.
Note: The temporary mobility kit contains
enough sealant compound in the canister
for one tire repair only. See an authorized
dealer for replacement sealant canisters.
TIRE SEALANT AND INFLATOR KIT
PRECAUTIONS WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death. WARNING:
Do not run the engine
when operating the air compressor unless
the vehicle is outdoors or in a
well-ventilated area.

CHANGING A FLAT TIRE
WARNING: If the tire pressure
monitor sensor becomes damaged it may
not function.
Note: The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies. If you must use a sealant, use
the Tire Mobility Kit sealant. Replace the tire
pressure monitoring system sensor and
valve stem on the wheel by an authorized
dealer after use of the sealant.
Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire while driving, do not apply
the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road. Have a flat serviced by an authorized dealer
in order to prevent damage to the tire
pressure monitoring system sensors.
See
Tire Pressure Monitoring System Overview
(page 385). Replace the spare tire with a road
tire as soon as possible. During repairing or
replacing of the flat tire, have an authorized
dealer inspect the tire pressure monitoring
system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,
then it is intended for temporary use only.
This means that if you need to use it, you
should replace it as soon as possible with a
road wheel and tire assembly that is the
same size and type as the road tires and
wheels that were originally provided on your
vehicle. If the dissimilar spare tire or wheel
is damaged, replace it instead of repairing
it. A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire assembly
that is different in brand, size or appearance
from the road tires and wheels and can be
one of three types:
1.
T-type mini-spare: This spare tire begins
with the letter T for tire size and may have
Temporary Use Only molded in the sidewall.
2.
Full-size dissimilar spare with label on
wheel: This spare tire has a label on the
wheel that states: THIS WHEEL AND TIRE
ASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar spare
tires listed above, do not:
• Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
