2. If the engine does not startafter 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 holding it there as
you hold 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,
follow the same steps. 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.Stop/Start System
{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.
If equipped, the stop/start system
helps to save fuel and reduce the
exhaust emissions.
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
0 112. When the brake pedal is
released or the accelerator pedal
pushed, the engine will restart. Auto Stop may be deactivated if:
.
A minimum vehicle speed is not
reached.
. The engine or transmission is
not at the required operating
temperature.
. The shift lever is in any gear
other than D (Drive).
. The battery charge is low.
. The interior comfort level has not
reached the required level for
the climate control system or
defog settings. See Dual
Automatic Climate Control
System 0148.
. The Auto Stop time is greater
than two minutes.

178 Driving and Operating
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
revolutions per minute (rpm):
.The transmission will not allow
shifting to the next higher gear if
the vehicle speed or engine rpm
is too low.
. The transmission will not allow
shifting to the next lower gear if
the vehicle speed or engine rpm
is too high.Drive Systems
All-Wheel Drive
If equipped, this feature transfers
engine power, as required, to all
four wheels. It is fully automatic ,
and adjusts itself as needed for road
conditions.
When using a compact spare tire on
an All-Wheel Drive (AWD) vehicle,
the system automatically detects the
compact spare and disables AWD to
protect the system. A Driver
Information Center (DIC) message
will display on the instrument
cluster. See Vehicle Messages
0 127. To restore AWD operation
and prevent excessive wear on the
system, replace the compact spare
with a full-size tire as soon as
possible. See Compact Spare Tire
0 260.
AWD will be disabled and the
message will display if there is
excessive wheel spin. When the
system cools down, AWD will be
restored.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
may be heard while this test is going
on, and it may even be noticed that
the brake pedal moves a little. This
is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
0 119.

Driving and Operating 179
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
To set the parking brake, hold the
brake pedal down and pull up on the
parking brake lever. If the ignition is
on, the brake system warning light
will come on. SeeBrake System
Warning Light 0118.
To release the parking brake, hold
the brake pedal down. Pull the
parking brake lever up until you can
press the release button. Hold the
release button in as you move the
brake lever all the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.

180 Driving and Operating
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
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 thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
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 0162
and “Turning the Systems Off and
On” later in this section.

Cruise Control
The cruise control lets the vehicle
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
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.
The vehicle has a Traction Control
System (TCS) or StabiliTrak system
that begins to limit wheel spin while
using cruise control and the cruise
control will automatically disengage. See
Traction Control/Electronic
Stability Control 0180. If a collision
alert occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0188. When
road conditions allow you to safely
use it again, cruise control can be
turned back on.
If the brakes are applied, cruise
control disengages.
o: Press to turn the cruise control
system on or off. A white indicator
comes in the instrument cluster
when cruise is turned on.

memory, move the thumbwheel up
briefly to resume to that speed or
hold upward to accelerate. If cruise
control is already active, use to
increase vehicle speed.
SET/− :Move the thumbwheel down
briefly to set the speed and activate
cruise control. If cruise control is
already active, use to decrease
speed.
n: Press to disengage cruise
control without erasing the set
speed from memory.
Setting Cruise Control
If
ois on when not in use, SET/−
or RES/+ could get bumped and go
into cruise when not desired. Keep
ooff when cruise control is not
being used.
To set a speed:
1. Press
oto turn cruise
control on.
2. Get up to the speed desired.
3. Move the thumbwheel down toward SET/− and release it. 4. Remove your foot from the
accelerator.
The cruise control indicator on the
instrument cluster turns green after
cruise control has been set to the
desired speed. See Instrument
Cluster 0109.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or
nis pressed, the
cruise control is disengaged without
erasing the set speed from memory.
Once the vehicle speed is about
40 km/h (25 mph) or greater, move
the thumbwheel up toward RES/+
briefly. The vehicle returns to the
previously set speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Move the thumbwheel up toward
RES/+ and hold it until the
desired speed is reached, then
release it. .
To increase vehicle speed in
small increments, move the
thumbwheel up toward RES/+
briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units.
See Driver Information Center (DIC)
(Uplevel) 0125 orDriver Information
Center (DIC) (Base Level) 0123.
The increment value used depends
on the units displayed.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Move the thumbwheel toward
SET/− and hold until the desired
lower speed is reached, then
release it.
. To decrease the vehicle speed in
small increments, move the
thumbwheel toward SET/−
briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) slower.

188 Driving and Operating
PARK ASSIST OFF :If the FRPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
. The driver has disabled the
system.
. The sensors are not clean. Keep
the vehicle's bumpers free of
mud, dirt, snow, ice and slush.
For cleaning instructions, see
Exterior Care 0267.
. The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
. An object was hanging out of the
liftgate during the last drive
cycle. Once the object is
removed, FRPA will return to
normal operation.
. An object or cover is attached to
the front of the vehicle. .
The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
. Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving 0156.
FCA can be disabled with either the
FCA steering wheel control or,
if equipped, through vehicle
personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0128.
