DRIVING AND OPERATING 221
.Holding both sides of the steering
wheel allows you to turn
180 degrees without removing
a hand.
.The Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer
the vehicle so that it straddles the
edge of the pavement. 2. Turn the steering wheel about
one-eighth of a turn, until the right
front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
.Acceleration Skid —too much
throttle causes the driving wheels
to spin.
Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible. If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
.Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer and
vehicle control can be affected when
traction is reduced by water, snow,
ice, gravel, or other material on the
road. Learn to recognize warning
clues
—such as enough water, ice,
or packed snow on the road to
make a mirrored surface —and
slow down when you have any
doubt.
.Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden changes
could cause the tires to slide.
Remember: Antilock brakes help avoid
only the braking skid.

DRIVING AND OPERATING 227
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
.Turn on Traction Control. See
Traction Control/Electronic Stability
Control0248.
.Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should be
applied sooner than when on dry
pavement. See Antilock Brake System
(ABS) 0246.
.Allow greater following distance and
watch for slippery spots. Icy patches
can occur on otherwise clear roads
in shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD) mode.
See Driver Mode Control 0250 and
All-Wheel Drive 0245.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. If possible,
use Roadside Assistance. See Roadside
Service 0401. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside. Engine
exhaust contains carbon monoxide
(CO), which cannot be seen or
smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking
the exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about 5 cm (2 in)
on the vehicle side that is away
from the wind, to bring in
fresh air.
.Fully open the air outlets on or
under the instrument panel.
.Adjust the climate control
system to circulate the air inside
the vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0239.
To save fuel, run the engine for short
periods to warm the vehicle and then
shut the engine off and partially close
the window. Moving about to keep
warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible, to save fuel.

starting the vehicle. An internal
thermostat in the plug end of the cord
will prevent engine heater operation
at temperatures above−18 °C (0 °F).
{Warning
Do not plug in the engine block
heater while the vehicle is parked in
a garage or under a carport.
Property damage or personal injury
may result. Always park the vehicle
in a clear open area away from
buildings or structures.
To Use the Engine Heater
1. Turn off the engine.
2. Remove the engine heater
connector cover by gently prying
with a flat-bladed tool at the
location of the notch along the top
edge of the cover.
3. Check the heater cord for damage.If it is damaged, do not use it. See
your dealer for a replacement.
Inspect the cord for damage yearly.
4. Plug the heater cord into theconnector in the front fascia.
5. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or
an extension cord can damage the
cord and may result in overheating
and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault

will not shift out of P (Park), see your
dealer for service.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the vehicle
and ignite. Do not park over papers,
leaves, dry grass, or other things
that can burn.
Active Fuel Management
This vehicle's engine may be equipped
with Active Fuel Management, which
allows the engine to operate on either
all of its cylinders, or in reduced
cylinder operation mode, depending
on the driving conditions.
When less power is required, such as
cruising at a constant vehicle speed,
the system will operate in reduced
cylinder operation mode, allowing the
vehicle to achieve better fuel economy.
When greater power demands are
required, such as accelerating from a
stop, passing, or merging onto a
freeway, the system will maintain
full-cylinder operation.
