All Wheel Drive (AWD) delivers engine
power to front and rear wheels for
maximum traction. AWD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE
• Do not drive in water if the level
is higher than the bottom of the
vehicle.
• Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.
• Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).
• Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.
• Be sure to equip all four tires with the
correct size and type.
• Make sure that a full time AWD
vehicle is towed by a flat bed tow
truck.
ALL WHEEL DRIVE (AWD) (IF EQUIPPED)

Driving Your Vehicle
6-42
For safe AWD operation
Before driving
• Make sure all passengers are wearing
seat belts.
• Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy roads
• Start off slowly by applying the
accelerator pedal gently.
• Use snow tires or tire chains.
• Keep sufficient distance between your
vehicle and the vehicle in front of you.
• Apply engine braking during
deceleration by using the paddle
shifter (manual shift mode) and
manually selecting a lower gear.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
Information
When using Snow Tires, mount them on
all four wheels.
When using tire chains, install them on the
rear tires. However, driving speed must
be below 20 mph (30 km/h) and minimize
the driving distance. High-speed or long-
term driving with tire chains installed may
malfunction or damage the AWD system.
For more details on Snow Tires and Tire
Chains, refer to "Winter Driving" section
later in this chapter.
Driving in sand or mud
• Maintain slow and constant speed.
• Use tire chains driving in mud if
necessary.
• Keep sufficient distance between your
vehicle and the vehicle in front of you.
• Reduce vehicle speed and always
check the road condition.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent getting stuck.
NOTICE
When the vehicle is stuck in snow, sand
or mud, place a nonslip material under
the drive wheels to provide traction
OR slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle.
However, avoid running the engine
continuously at high RPM, doing so may
damage the AWD system.
Driving up or down hills
• Driving uphill
- Before starting off, check if it is
possible to drive uphill.
-Drive as straight as possible.
• Driving downhill
-Do not change gear while driving
downhill. Select gear before driving
downhill.
-Drive slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may roll
over depending on the grade, terrain,
water and mud conditions.

Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:
• Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare
from other drivers’ headlamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.
• Avoid staring directly at the
headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
• Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.
• Turn OFF your Cruise Control. (if
equipped)
• Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.
• Be sure your tires have enough tread.
If your tires do not have enough tread,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. See “Tire Tread” section
in chapter 9.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to “Tire Tread” section in chapter 9.
