Driving and Operating 205CautionCranking the engine for long
periods of time, by returning the
ignition to the START position
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 holding it there as
you press ENGINE START/
STOP. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts,
release 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.
Stop/Start System
{ WarningExiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle has the auto engine stop/
start feature, the vehicle's engine
might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel. 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
0 124 . When the brake pedal is
released or the accelerator pedal is
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 outside temperature is not
in the required operating range,
typically between − 10 °C (14 °F)
and 50 °C (122 °F).
.
The shift lever is in any gear
other than D (Drive).
.
The battery has been recently
disconnected.

Driving and Operating 213Tap Shift Mode can also be
deactivated by holding the right
upshift control briefly.
While using Tap Shift, the vehicle
will have firmer, quicker shifting. You
can use this for sport driving or
when climbing or descending hills,
to stay in gear longer, or to
downshift for more power or engine
braking.
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 downshift if the
engine rpm is too high in the next
lower gear, or upshift to the next
higher gear when the maximum
engine rpm is reached. If shifting is prevented for any
reason, a SHIFT DENIED message
will be displayed in the instrument
cluster. See Transmission
Messages 0 156 .
When accelerating the vehicle from
a stop in snowy and icy conditions,
it is suggested to shift into second
gear. A higher gear allows the
vehicle to gain more traction on
slippery surfaces.
Drive Systems All-Wheel Drive Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.

Driving and Operating 215The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a red parking brake
status light and an amber parking
brake warning light. See Electric
Parking Brake Light 0 134
and Service Electric Parking Brake
Light 0 134 . There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0 147 . In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a
complete stop.
2. Press the EPB switch
momentarily. The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See Electric
Parking Brake Light 0 134 .
If the amber parking brake warning
light is on, press the EPB switch
and hold it. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pressed. If the switch is pressed
until the vehicle comes to a stop,
the EPB will remain applied. The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
EPB Release To release the EPB:
1. Place the ignition in the ACC/
ACCESSORY or ON/
RUN mode.
2. Apply and hold the brake
pedal.
3. Push down momentarily on the
EPB switch.

218 Driving and Operating vehicle 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 0 198
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
d comes 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
d comes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
4. Drive the vehicle.
If
d comes on and stays on, the
vehicle may need more time to
diagnose the problem. If the
condition persists, see your dealer.

220 Driving and Operating If the vehicle is equipped with AWD,
the Tour mode is in between the
Sport and the Snow/Ice modes for a
more balanced feel.
Sport Mode Use where road conditions or
personal preference demand a more
controlled response.
When selected, the Sport mode
indicator will display in the Driver
Information Center (DIC).
When in Sport mode, the vehicle will
shift automatically but may hold a
lower gear longer than it would in
the normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. See Automatic
Transmission 0 210 . The steering,
including Active Rear Steer (if
equipped), will change to provide
more precise control.
If the vehicle is equipped with AWD,
the Sport mode sends more torque
to the rear wheels. Snow/Ice Mode Use when more traction is needed
during slippery conditions. Snow/Ice
mode will use a different accelerator
pedal map in order to optimize
traction on slippery surfaces.
When selected, the Snow/Ice mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the

If the vehicle is equipped with AWD,
the Snow/Ice mode will provide
more torque to the front wheels. Cruise Control
{ WarningCruise 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.
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).
