not use Line Lock in an area
that is accessible to the
public or where people or
property are located near
the vehicle.
Caution
Attempting to shift when
the drive wheels are
spinning and do not have
traction may cause damage
to the transmission. Damage
caused by misuse of the
vehicle is not covered by the
vehicle warranty. Do not
attempt to shift when the
drive wheels do not have
traction.
Line Lock allows for locking
the front brakes
independently of the rear
brakes. This allows the rear
tires to spin when the throttle
is applied. To enter Line Lock, all of
these conditions must be met:
.The vehicle must be in
Track Mode.
.Performance Traction
Management (PTM) Mode
must be enabled.
.The steering wheel must be
straight.
.The driver door must be
closed.
.The vehicle must be in D
(Drive) for an automatic
transmission or 1 (First) gear
for a manual transmission.
.The parking brake must not
be engaged.
.The vehicle must be stopped
on level ground. The
accelerator pedal must not
be applied.

Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop

Driving and Operating 253
.Shift to a lower gear when
going down steep or long
hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill
slope can cause brake
overheating, can reduce
brake performance, and
could result in a loss of
braking. Shift the
transmission to a lower gear
to let the engine assist the
brakes on a steep downhill
slope.
{Warning
Coasting downhill in
N (Neutral) or with the
ignition off is dangerous.
This can cause overheating
of the brakes and loss of
steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain 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 Control
0
290.
.The 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) 0286.
.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 for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0292 and
All-Wheel Drive 0286.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan
speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
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 Assistance Program

487. 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
0 271.
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

Driving and Operating 255
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.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control0290.
If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See “Rocking
the Vehicle to Get it Out”
following.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
(Continued)
Warning (Continued)
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. 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 when
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see

262 Driving and Operating
The vehicle may have an
electric steering column lock.
The lock is activated when the
vehicle is switched to OFF and
the driver door is opened.
A sound may be heard as the
lock actuates or releases. The
steering column lock may not
release with the wheels
turned off center. If this
happens, the vehicle may not
start. Move the steering wheel
from left to right while
attempting to start the
vehicle. If this does not work,
the vehicle needs service.
Do not turn the engine off
when the vehicle is moving.
This will cause a loss of power
assist in the brake and
steering systems and disable
the airbags.
If the vehicle must be shut off
in an emergency:1. Brake using a firm and steady pressure. Do not
pump the brakes
repeatedly. This may deplete power assist,
requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an
automatic transmission,
or Neutral with a manual
transmission. Turn the
ignition off.
4. Set the parking brake. See Electric Parking Brake
0287.
{Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency. If the vehicle cannot be pulled
over, and must be shut off
while driving, press and hold
ENGINE START/STOP for
longer than two seconds,
or press twice within
five seconds.
Accessory Mode (Amber
Indicator Light) :
This mode
allows the use of some
electrical accessories when
the engine is off.
With the ignition off, pressing
the button once without the
brake pedal applied will place
the ignition system in

rock the vehicle back and forth
to get out of snow, ice, or sand
without damaging the
transmission. See If the
Vehicle Is Stuck 0255.
N : In this position, the engine
does not connect with the
wheels. To restart the engine
when the vehicle is already
moving, use N (Neutral) only.
{Warning
Shifting into a drive gear
while the engine is running
at high speed is dangerous.
Unless your foot is firmly on
the brake pedal, the vehicle
could move very rapidly. You
could lose control and hit
people or objects. Do not
shift into a drive gear while
the engine is running at high
speed.
Caution
