USING ALL-WHEEL DRIVE
Note:
When a system malfunction is present,
a warning message appears in the
information display. See Information
Messages (page 128). This means the system
is not functioning correctly and only
front-wheel drive is available. Have your
vehicle checked by an authorized dealer.
Note: When the system overheats and
switches to front-wheel drive, a warning
message appears in the information display.
This may occur if you operate your vehicle
in extreme high load conditions or with
excessive wheel spin (for example, deep
sand). To resume all-wheel drive function,
stop your vehicle in a safe location and turn
off the ignition. When the system cools,
normal all-wheel drive function will return.
Note: When using the spare tire, a warning
message may appear in the information
display. This message turns off after
reinstalling the repaired or replaced road
tire and you switch on the ignition. Note:
Re-install the repaired tire or replace
the tire as soon as possible. Different tire
sizes between the front and rear axles can
cause system damage, or turn off the
all-wheel drive.
This system anticipates wheel spin and
transfers power to the rear wheels before
the spin occurs. Even when wheel spin is not
occurring, the system is continuously
adjusting power distribution to the wheels,
in an attempt to improve straight line and
cornering, both on and off road.
The system automatically turns on every time
you switch on the ignition.
The all-wheel drive system does not require
maintenance.
Your all-wheel drive vehicle is not intended
for off-road use. The AWD feature gives your
vehicle some limited off-road capabilities in
which driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions. Operating
your vehicle in other than those conditions
could subject your vehicle to excessive
stress which might result in damage that is
not covered under your vehicle warranty. The information display indicates the power
distribution between the front and rear
wheels. The more the area is filled, the more
power is being distributed to that wheel.
Driving in Special Conditions With All-
Wheel Drive
All-wheel drive has operating characteristics
that are somewhat different from two-wheel
drive, both on and off the freeway.
Note:
It may be useful to switch the traction
control off. This allows for more wheel spin
and engine torque in certain off road
conditions or if your vehicle becomes stuck.

When driving at slow speeds off road under
high load conditions, use a low gear when
possible. Low gear operation will maximize
the engine and transmission cooling
capability.
Under severe operating conditions, the air
conditioning may cycle on and off to prevent
the engine from overheating.
Basic Operating Principles
•
Drive slower in strong crosswinds that
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice, proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
Once you have reduced your vehicle speed,
ease your vehicle back onto the road. Do
not turn the steering wheel sharply while
returning your vehicle to the road. It may be safer to stay on the shoulder of the
road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than attempt
an abrupt dangerous direction change.
Remember, your primary concern should be
your safety and the safety of others.
Emergency Maneuvers
If you must make a sudden emergency
direction change, avoid over-driving your
vehicle. Turn the steering wheel only as
rapidly and as far as you need to avoid the
emergency. Apply smooth pressure to the
accelerator pedal or brake pedal as needed.
Avoid abrupt steering, acceleration and
braking changes. Abrupt changes could
increase the risk of vehicle roll over, loss of
vehicle control and personal injury. Use all
available road surfaces to bring your vehicle
under control.In the event of an emergency stop, avoid
skidding and do not attempt any sharp
steering wheel movements.
Your vehicle responds differently to steering,
accelerating and braking on different road
surfaces when changing from one type of
surface to another.
Sand
When driving over sand, avoid driving at
excessive speeds. This will cause your
vehicle momentum to work against you. Your
vehicle could become stuck and that may
require assistance from another vehicle.
Remember, if you proceed with caution you
may be able to back out the way you came.
Do not drive in deep sand for an extended
period. This will cause the all-wheel drive
system to overheat. You will see a warning
message in the information display. See
Information Messages (page 128).

Start climbing a steep slope or hill in a low
gear rather than downshifting to a low gear
from a high gear after you have started your
climb. This reduces strain on the engine and
the possibility of stalling.
If your vehicle stalls, do not try to turn
around. Turning could cause the vehicle to
roll over. Instead, reverse back to a safe
location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, and you
could lose control of your vehicle. To avoid brake overheating, come down a
hill in the same gear you used to go up the
hill. Do not come down in neutral. Move the
transmission selector lever to a lower gear.
When descending a steep hill, avoid sudden
hard braking to keep the front wheels rolling
and to maintain your vehicle's steering.
Your vehicle has anti-lock brakes. Apply the
brakes steadily. Do not pump the brake
pedal.
Driving on Snow and Ice
WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle.
Note: Excessive tire slippage can cause
transmission damage. In snow and ice, all-wheel drive vehicles have
advantages over two-wheel drive vehicles
but can still skid. When driving on snowy or
icy roads, should you start to slide, turn the
steering wheel in the direction of the slide
until you regain control.
On snow and ice, avoid suddenly applying
power and avoid quick change of direction.
Apply the accelerator slowly and steadily
when starting from a stop.
Avoid sudden braking. An all-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in snow and ice.
However, an all-wheel drive vehicle will not
stop any faster, as braking occurs at all four
wheels. Do not become overconfident to
road conditions.

Make sure that you allow sufficient distance
between your vehicle and other vehicles for
stopping. On ice and snow, you should drive
more slowly than usual, and consider using
one of the lower gears. In emergency
stopping situations, steadily apply the brake.
Your vehicle has a four wheel anti-lock brake
system, do not pump the brake pedal. See
Hints on Driving With Anti-Lock Brakes
(page
215).
If Your Vehicle Gets Stuck In Mud or Snow
If your vehicle becomes stuck in mud or
snow, shift between forward and reverse
gears, and, in a steady pattern, stop between
shifts. Press lightly on the accelerator with
each shift. Rocking your vehicle this way may
dislodge your vehicle.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, damage to the transmission and
tires may occur or the engine may overheat. Maintenance and Modifications
The suspension and steering systems on
your vehicle provides predictable
performance whether your vehicle is loaded
or empty. For this reason, we recommend
that you do not make modifications to your
vehicle (lift kits or stabilizer bars) or use
replacement parts not equivalent to the
original factory equipment.
We recommend that you use caution when
your vehicle has either a high load or device
(ladder or luggage racks). Modifications to
your vehicle that raise the center of gravity
may cause your vehicle to tip if you should
lose vehicle control.
Failure to maintain your vehicle correctly may
void the warranty, increase your repair cost,
reduce vehicle performance and operational
capabilities, and adversely affect you and
your passenger's safety. We recommend that
you frequently inspect your vehicle's chassis
components if your vehicle is subject to
off-road use.

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle
’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES WITH:

Trailer Lamps
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles. When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective. •
If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.

Note:
If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Capacities and Specifications (page 385).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications
(page 385).
3. Add enough prediluted coolant to reach
the correct level. 4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing. Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards for
recycling and disposing of automotive fluids.

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
385).
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.
