to the floor while cranking for up
to 15 seconds maximum. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine.
{Caution
Cranking 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.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever to
P (Park) and press and hold theENGINE START/STOP button on
the instrument panel, until the
engine shuts off. If the shift lever is
not in P (Park), the engine shuts off
and the vehicle goes into the
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, move the shift
lever to R (Reverse) and set the
parking brake after turning off the
engine by pressing and holding the
ENGINE START/STOP button.
If the RKE transmitter is not
detected inside the vehicle when it
is turned to off, the DIC displays a
message.

Leaving the Vehicle with the
Engine Running (Automatic
Transmission)
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
(Continued)
Warning (Continued)
move the shift lever to P (Park).
SeeShifting Into Park on
page 9-23.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
down the regular brake pedal. See if
you can move the shift lever away
from P (Park) without first pushing
the button on the lever. If you can, it
means that the shift lever was not
fully locked into P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle may put too much force on
the parking pawl in the
transmission. You may find it difficult to pull the shift lever out of P (Park).
This is called
“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
“Shifting Into P (Park)” previously in
this section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the transmission
parking pawl, so you can pull the
shift lever out of P (Park).
Shifting out of Park
Shift lock release prevents shifting
out of P (Park) unless the vehicle is
running or in accessory mode and
the brake pedal is applied.

The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. SeeJump Starting
on page 10-79.
To shift out of P (Park):
1. Apply the brake pedal.
2. Release the parking brake. See Electric Parking Brake on
page 9-35.
3. Press the shift lever button.
4. Move the shift lever to the desired position.
If you still are unable to shift out of
P (Park):
1. Fully release the shift lever button, and let go of the
shift knob.
2. While holding down the brake pedal, press the shift lever
button again.
3. Move the shift lever to the desired position. If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
Parking (Manual
Transmission)
Before exiting the vehicle, move the
shift lever into 1 (First) or
R (Reverse), and apply the parking
brake. Once the shift lever has been
placed into 1 (First) or R (Reverse)
with the clutch pedal pressed in,
turn the ignition off and release the
clutch.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management®
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco mode. See
Driver
Mode Control on page 9-39.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.

Automatic
Transmission
There are several different positions
for the shift lever.
P (Park):This position locks the
rear wheels. It is the best position to
use when starting the engine
because the vehicle cannot move
easily.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park on
page 9-23.
Be sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. Fully apply the brakes and
then press the shift lever button
before shifting from P (Park) when
the vehicle is running. If the vehicle cannot be shifted out of P (Park),
ease pressure on the shift lever and
push the shift lever all the way into
P (Park) as brake application is
maintained. Then press the shift
lever button and move the shift lever
into another gear. See
Shifting out
of Park on page 9-24.
R (Reverse): Use this gear to
back up.
{Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle Is Stuck on page 9-13.

downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster,
or the Head-Up Display (HUD),
if equipped. SeeHead-Up Display
(HUD) on page 5-29.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) or 3 (Third)
gear allows the vehicle to gain more
traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive). When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator by the shift lever, in
the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission will
select 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicles speed.
If the paddle continues to be held as
the vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but the driver must first
press and release the (−) minus
paddle to enter Temporary Manual
Paddle Shift mode, then press and
hold the (−) minus paddle briefly.
The Manual Paddle Shift system will
not allow either an upshift or a
downshift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the cluster and HUD.

normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/ACCESSORY or ON/RUN
position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.
{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.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and
accelerator pedals in preparation for
starting the vehicle moving in the intended direction. In this case,
there is no need to push the switch
to release the EPB.
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

Driving and Operating 9-37
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
If equipped, HSA may automatically
activate when the vehicle is stopped
on a grade. This feature is designed
to prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. During the
transition from releasing the brake
pedal to accelerating to drive off on
a grade, HSA holds the braking
pressure to prevent rolling. HSA will
not activate if the vehicle is in a
drive gear and facing downhill or if
the vehicle is facing uphill and in
R (Reverse).
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak
system. These systems help limit
wheel spin and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) 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 when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control on
page 9-48.
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 9-13 and“Turning the
Systems Off and On” later in this
section.
