.Maintain a reasonable
steady speed through the
curve.
.Wait until the vehicle is out
of the curve before
accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations
when steering around a
problem may be more
effective than braking.
.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.

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

264 Driving and Operating
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information
Center (DIC) message will
display. See Remote Key
Operation09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow
the cranking motor to cool
down. When the engine
starts, let go of the button
and the accelerator. If the
vehicle starts briefly but
then stops again, do the
same thing. This clears the
extra gasoline from the
engine. Do not race the
engine immediately after
starting it. Operate the
engine and transmission
gently until the oil warms
up and lubricates all
moving parts.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift
lever to P (Park) and press and
hold ENGINE START/STOP on
the instrument panel, until the
engine shuts off. If the shift
lever is not in P (Park), the
engine shuts off and the
ignition goes to accessory
mode. The DIC displays SHIFT
TO PARK. Once the shift lever
is moved to P (Park), the
vehicle turns off.
If the vehicle has a manual
transmission, before getting
out of the vehicle, shift to
1 (First) or R (Reverse) and
apply the parking brake. Then
turn off the ignition off by
pressing ENGINE START/
STOP and release the clutch
pedal when the engine has
stopped.
If the remote key is not
detected inside the vehicle
when it is turned off the DIC
displays a message.
Stop/Start System
If equipped, the Stop/Start
system will shut off the engine
to help conserve fuel. It has
components designed for the
increased number of starts.

Caution
A transmission hot message
may display if the automatic
transmission fluid is too hot.
Driving under this condition
can damage the vehicle.
Stop and idle the engine to
cool the automatic
transmission fluid. This
message clears when the
transmission fluid has cooled
sufficiently.
D : This position is for normal
driving. If more power is
needed for passing, press the
accelerator pedal down.
Downshifting the transmission
in slippery road conditions
could result in skidding. See
“Skidding” under Loss of
Control 0237. M :
This mode can be entered
by moving the shift lever from
D (Drive) to M (Manual Mode).
M (Manual Mode) allows the
driver to select gears
appropriate for current driving
conditions. M (Manual Mode)
can be exited by returning the
shift lever to D (Drive). See
Manual Mode (Electronic
Shifter) 0281 or
Manual Mode (Mechanical
Shifter) 0280.
Caution
Spinning the tires or holding
the vehicle in one place on a
hill using only the
accelerator pedal may
damage the transmission.
The repair will not be
covered by the vehicle
warranty. If the vehicle is
stuck, do not spin the tires.
When stopping on a hill, use
the brakes to hold the
vehicle in place. While in Sport or Track Mode,
the vehicle monitors driving
behavior, and automatically
enables Performance Shift
Features when spirited driving
is detected. These features
maintain lower transmission
gears to increase available
engine braking and improve
acceleration response. The
vehicle will exit these features
and return to Sport or Track
Mode normal operation after a
short period when no spirited
driving is detected. See Driver
Mode Control
0292.
Engine speeds may be
increased while driving at
highway speeds while the
engine is still warming up.

{Warning
Do not rely on this feature.
It does not replace the need
to pay attention and drive
safely. You may not hear or
feel alerts or warnings
provided by this system.
Failure to use proper care
when driving may result in
injury, death, or vehicle
damage.
When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
indicator light on the switch
will come on. The AVH light on
the instrument panel will come
on while AVH is actively
holding the vehicle. See
Automatic Vehicle Hold (AVH)
Light
0122.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel slip and assist the driver in maintaining
control, especially on slippery
road conditions.
TCS activates if it senses that
any of the drive wheels are
spinning or beginning to lose
traction. When this happens,
the system brakes the
spinning wheel(s) and/or
reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the computer senses a
difference between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the intended
direction.
If cruise control is being used
and TCS or StabiliTrak/ESC
begins to limit wheel spin,
cruise control will disengage.
Cruise control may be turned
back on when road conditions
allow.
