206 DRIVING AND OPERATING
.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 213
.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 Ice
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
Control0239.
.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) 0236.
See Driver Mode Control 0241.
.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.
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 Service. See Roadside
Service 0403. 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.
.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 0226.

DRIVING AND OPERATING 221
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. SeeRemote
Keyless Entry (RKE) System
Operation 07.
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
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 ACC/
ACCESSORY. The DIC displays SHIFT
TO PARK. Once the shift lever is
moved to P (Park), the vehicle
turns off.
If the remote key is not detected
inside the vehicle when it is turned off
the DIC displays a message.
Stop/Start System
The Stop/Start system will shut off
the engine to help conserve fuel.
It has components designed for the
increased number of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.
Auto Engine Stop/Start
When the brakes are applied and the
vehicle is at a complete stop, the
engine may turn off. When stopped,
the tachometer displays AUTO STOP.
See Tachometer 093. When the brake
pedal is released or the accelerator
pedal is pressed, the engine will
restart.

DRIVING AND OPERATING 229
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”underLoss
of Control 0206.
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) 0235 or
Manual Mode (Mechanical Shifter)
0 234.
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 0241. Engine speeds may be increased while
driving at highway speeds while the
engine is still warming up.
Automatic Transmission
(Electronic Shifter)
The shift pattern is displayed in the
top of the shift lever. The selected
gear position will illuminate red on
the shift lever, while all others will be
displayed in white. If the shift is not
immediate, as in very cold conditions,
the indicator on the shift lever may
flash until it is fully engaged.

DRIVING AND OPERATING 239
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must come to
a complete stop on a grade for HSA to
activate.
Automatic Vehicle
Hold (AVH)
{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(Continued)
Warning (Continued)
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 0101.
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

This mode provides a balance between
comfort and handling. This is the
standard mode. See “Mode Selection Attributes”
later in this section. When
Tour Mode is selected, no indicator
will display.
Sport Mode
Use this mode where road conditions
or personal preference demand a more
controlled response. When this mode
is selected, the vehicle immediately
downshifts. The vehicle also monitors
driving behaviors 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 this feature and return to normal
operation after a short period when
spirited driving is no longer detected.
The steering changes to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
changes to provide better cornering
performance.
See “Mode Selection Attributes ”later
in this section. Snow/Ice Mode
Use this mode for slippery surfaces to
help control wheel speed. This mode
can compromise the acceleration on
dry asphalt.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, or gravel. If the vehicle is stuck,
see
If the Vehicle Is Stuck 0214.
See “Mode Selection Attributes ”later
in this section.
Track Mode (V-Series Only)
When in Track Mode, the automatic
transmission and steering function
similar to Sport Mode. The accelerator
pedal is adjusted to give maximum
control during the highest level of
spirited driving. The Magnetic Ride
Control will be set to the optimum
level for vehicle responsiveness.
Performance Traction Management
(PTM) can be accessed through this
mode. See “Performance Traction
