Emergency Precautions
Tires
When replacing the tires, be sure to
equip all four tires with the same
size, type, tread, brand and load-car-
rying capacity.
In an emergency situation, a com-
pact spare tire may be used. But, do
not use the compact spare tire con-
tinuously. Repair or replace the origi-
nal tire as soon as possible to avoid
failure of the differential or AWD sys-
tem.
Tire size mismatch. Check all tire
sizes.
If your vehicle is equipped with differ-
ent tires (size, type, etc.) on the front
and rear, the message will appear. To
use the AWD system, equip the vehi-
cle with the same tires on the front
and rear.

Driving your vehicle
Do not use tire and wheel with
different size and type from the
one originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to steering
failure or rollover causing seri-
ous injury.
WARNING
OHI058226L
Never start or run the engine
while an AWD vehicle is raised
on a jack. The vehicle can slip or
roll off of a jack causing serious
injury or death to you or those
nearby.

Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
below suggestions:
• Drive cautiously and keep a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in snow,
mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
• Put sand, rock salt, tire chains or
other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
stuck in ice, snow, or mud.
Rocking the Vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-
tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.
SPECIAL DRIVING CONDITIONS
Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING
If the vehicle is stuck and
excessive wheel spin occurs,
the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehi-
cle, the vehicle can overheat
quickly, possibly causing an
engine compartment fire or
other damage. Try to avoid spin-
ning the wheels as much as
possible to prevent overheating
of either the tires or the engine.
DO NOT allow the vehicle to
spin the wheels above 35 mph
(56 km/h).
WARNING

5-151

Information
The ESC system must be turned OFF
before rocking the vehicle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid engine overheating, pos-
sible damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
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 dis-
tance between you and other vehi-
cles, 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 driver's head-
lamps.
• 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 head-
lamps 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 follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
• Turn OFF your Cruise Control.
• 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 Replacement" in chap-
ter 7.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large pud-
dles 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 driv-
ing 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 decreas-
es, refer to "Tire Replacement" in
chapter 7.

Driving your vehicle
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
i
Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles. To pre-
vent rollovers or loss of control:
• Take corners at slower speeds
than you would with a passen-
ger vehicle.
• Avoid sharp turns and abrupt
maneuvers.
• Do not modify your vehicle in
any way that you would raise
the center of gravity.
• Keep tires properly inflated.
• Do not carry heavy cargo on
the roof.
WARNING
In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Make sure all
passengers are wearing their
seat belts.
WARNING

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
Snow tires
We recommend you use snow tires when road temperature is below 45°F
(7°C). Refer to the below chart, and mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. Mount snow tires on
all four wheels to balance your vehicle's handling in all weather conditions.
The traction provided by snow tires on dry road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

Tire chains
Since the sidewalls on some radial
tires are thinner than other types of
tires, they may be damaged by
mounting certain types of tire chains
on them. Do not mount tire chains on
vehicles equipped with aluminum
wheels; if unavoidable use AutoSock
®
(fabric snow chain or similar).Install
AutoSock®after reviewing the
instructions provided with
AutoSock
®. Damage to your vehicle
caused by improper use of fabric
snow chains are not covered by your
vehicle manufacturer's warranty.AutoSock
®is a Registered trade-
mark of AutoSock.
Information
• Install AutoSock®(fabric snow
chain) on the rear tires. It should be
noted that installing AutoSock
®on
the tires will provide a greater driv-
ing force, but will not prevent side
skids.
• Do not install studded tires without
first checking local, state and
municipal regulations for possible
restrictions against their use.
i
The use of AutoSock®(fabric
snow chain) may adversely
affect vehicle handling:
• Drive less than 20 mph (30
km/h) or the AutoSock
®manu-
facturer's recommended
speed limit, whichever is
lower.
• Drive carefully and avoid
bumps, holes, sharp turns,
and other road hazards, which
may cause the vehicle to
bounce.
• Avoid sharp turns or locked
wheel braking.
