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 andthen, 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 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.

Driving and Operating 9-7
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Be alert on top of hills;
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C (32°
F) when freezing rain begins to fall,
resulting in even less traction. Avoid
driving on wet ice or in freezing rain
until roads can be treated with salt
or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
If equipped, Traction Control should
be turned on. SeeTraction Control/
Electronic Stability Control on
page 9-30. The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but
apply the brakes sooner than when
on dry pavement.
Allow greater following distance on
any slippery road 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.
See
Antilock Brake System (ABS)
on page 9-26.
Turn off cruise control on slippery
surfaces.

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.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction
Control/Electronic Stability Control
on page 9-30.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others 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 Towing the Vehicle on
page 10-83.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory-installed options.
Two labels on the vehicle show
how much weight it may
properly carry, the Tire and
Loading Information label and
the Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the

9-30 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
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, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path. Trailer Sway Control
(TSC) is also on automatically when
the vehicle is started. See
Trailer
Sway Control (TSC) on page 9-66.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
If the Vehicle Is Stuck on
page 9-9 and“Turning the Systems
Off and On” later in this section.The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak is
activated.
.Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in

maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

9-32 Driving and Operating
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand, or gravel. When
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. The
limited-slip rear axle also gives the
driver enhanced control when
cornering hard or completing a
maneuver, such as a lane change.
Selective Ride Control
The vehicle may have a ride control
system called Selective Ride
Control. The setting can be changed
at any time. Based on road
conditions, steering wheel angle,
and the vehicle speed, the system
automatically adjusts to provide the
best handling while providing a
smooth ride. The Tour and Sport
modes will feel similar on a
smooth road.
Tour:Use for normal city and
highway driving. This setting
provides a smooth, soft ride. Sport:
Use where road conditions
or personal preference demand
more control. This setting provides
more “feel,” or response to road
conditions through increased
steering effort and suspension
control. Transmission shift points
and shift firmness are also
enhanced.
The vehicle is normally in the Tour
Mode. To switch from Tour Mode to
Sport Mode, move the shift lever to
the left while the transmission is in
D (Drive). Sport Mode is
automatically engaged when the
shift lever is moved to the left.
Moving the shift lever forward or
rearward will put the transmission in
the M (Manual) Mode.
The Driver Information Center (DIC)
will display SPORT MODE ON
when the Sport Mode has been
activated. When the shift lever is
moved to the right in D (Drive), the
system will revert back to Tour
Mode. See Manual Mode on
page 9-24 under Automatic
Transmission. If there is a problem detected with
Selective Ride Control, SERVICE
SUSPENSION SYSTEM displays
on the DIC. See
Ride Control
System Messages on page 5-35.
Driving should be adjusted
accordingly.

Driving and Operating 9-33
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use the
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the StabiliTrak
®system begins to
limit wheel spin while using cruise
control, the cruise control
automatically disengages. See
Traction Control/Electronic
Stability Control on page 9-30. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System on page 9-48.
When road conditions allow the
cruise control to be safely used, you
can apply the cruise control again.
If the brakes are applied, cruise
control disengages.
J(On/Off): Press to turn the
system on and off. A white indicator
appears in the instrument cluster
when cruise is turned on.
+RES (Resume/Accelerate): If
there is a set speed in memory,
press the control up briefly to
resume to that speed or press and
hold to accelerate. If cruise control
is already active, use to increase
vehicle speed.
SET− (Set/Coast): Press the
control down briefly to set the speed
and activate cruise control. If cruise
control is already active, use to
decrease vehicle speed.
*(Cancel): Press to disengage
cruise control without erasing the
set speed from memory.
Setting Cruise Control
If the
5button is on when not in
use, SET− or RES+ could get
pressed and the vehicle could go

Driving and Operating 9-35
override cruise control, briefly
pressing SET−will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
the cruise control will disengage.
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.To turn off the cruise control,
press
J. Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See Radio
Frequency Statement on
page 13-12.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake. If ACC is controlling your vehicle
speed when the traction control
system (TCS) or electronic stabilty
control system activates, the ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control on page 9-30. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
ACC will not engage if the TCS or
StabiliTrak electronic stability control
system is disabled.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.

ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle when:
.The sensors are blocked.
.The Traction Control System
(TCS) or electronic stability
control system has activated or
been disabled.
.There is no traffic and nothing to
detect on the side of the road.
.There is a fault in the system.
.The brakes get heated.
The ACC active symbol will not be
displayed when ACC is no longer
active.
Notification to Resume ACC
ACC will maintain a follow time/
distance gap behind a detected
vehicle and slow your vehicle to a
stop behind that vehicle. If the vehicle ahead has driven
away and ACC has not resumed,
the vehicle ahead symbol will flash
as a reminder. In addition, the left
and right sides of the Safety Alert
Seat will pulse three times, or three
beeps will sound. See
”Alert Type”
and “Go Notifier” in“Collision/
Detection Systems” underVehicle
Personalization on page 5-38.
When the vehicle ahead drives
away, press +RES or the
accelerator pedal to resume ACC.
If stopped for more than
two minutes or if the driver door is
opened and the driver safety belt is
unbuckled, the ACC automatically
applies the electric parking brake to
hold the vehicle. The electric
parking brake status light will turn
on. See Parking Brake on
page 9-27. To release the electric
parking brake, press the accelerator
pedal.
A DIC warning message may
display indicating to shift to P (Park)
before exiting the vehicle. See
Vehicle Messages on page 5-27.
{Warning
If ACC has stopped the vehicle,
and if ACC is disengaged, turned
off, or canceled, the vehicle will
no longer be held at a stop. The
vehicle can move. When ACC is
holding the vehicle at a stop,
always be prepared to manually
apply the brakes.
{Warning
Leaving the vehicle without
placing it in P (Park) can be
dangerous. Do not leave the
vehicle while it is being held at a
stop by ACC. Always place the
vehicle in P (Park) and turn off
the ignition before leaving the
vehicle.
