SPECIAL DRIVING
CONDITIONS
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:
• Drive cautiously and maintain 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
unnecessary wheel spin.
• Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
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
downshifting on slippery surfaces.
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 forward 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 accelerator 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.

Driving Your Vehicle
6-52
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 vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damage. Try to avoid spinning 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).
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
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, possible damage to
the transmission, and tire damage. See
“Towing” section in chapter 8.
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 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.

06
6-53
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 depth
of tire 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.
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 several
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 specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
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.

The severe weather conditions of winter quickly wear out tires and cause other
problems. To minimize winter driving problems, you should take the following
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 applications, and
sharp turns are potentially very hazardous practices. During deceleration, 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
WARNING
Snow tires should be equivalent in size and type to the vehicle’s standard tires.
Otherwise, the safety and handling of your vehicle may be adversely affected.
We recommend that 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. 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 roads
may not be as high as your vehicle’s original equipment tires. Check with the tire dealer
for maximum speed recommendations.

Tire chains
ORG3060025
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.
Information
AutoSock® is a Registered trademark of
AutoSock.
WARNING
The use of AutoSock® (fabric snow
chain) may adversely affect vehicle
handling:
• Drive less than 20 mph (30 km/h)
or the AutoSock® manufacturer’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.
Information
• Install AutoSock® (fabric snow chain)
only in pairs and on the rear tires.
It should be noted that installing
AutoSock (fabric snow chain) on the
tires will provide a greater driving
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.
