204 Driving and Operating
Automatic
Transmission
The shift switches are on the front
shift console. The selected gear
position will illuminate red on the
shift switch, while all others will be
displayed in white. If the shift is not
immediate, as in very cold
conditions, the indicator on the shift
switch may blink until it is fully
engaged.
The transmission does not operate
when the vehicle is off.If the vehicle is in ACC/
ACCESSORY, the transmission can
be shifted into P (Park).
If ENGINE START/STOP is pressed
twice while at a relatively high
speed, the engine will turn off and
the transmission will automatically
shift to N (Neutral). Once the vehicle
is stopped, P (Park) can be
selected.
P :
This position locks the drive
wheels. Use P (Park) when starting
the vehicle to ensure the vehicle
does not move.{Warning
It is dangerous to get out of the
vehicle if the transmission is not
in P (Park) with the parking brake
set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If the engine
has been left running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
(Continued)
Warning (Continued)
vehicle will not move, even when
on fairly level ground, always set
the parking brake and place the
transmission into P (Park).
SeeShifting Into Park 0192 and
Driving Characteristics and
Towing Tips 0251.
This vehicle is equipped with an
electronic transmission. The
R (Reverse) and D (Drive) shift
switches are designed to prevent
inadvertent shifting out of P (Park)
unless the ignition is on, and the
brake pedal is applied.
For vehicles with a diesel engine,
the vehicle does not need to be on
to shift out of P (Park).
When the vehicle is stopped, press
ENGINE START/STOP to turn off
the vehicle. The transmission will
shift to P (Park) automatically.
The vehicle will not shift into

back and forth to get out of snow,
ice, or sand without damaging the
transmission. See If the Vehicle Is
Stuck 0180. N :
In this position, the engine does
not connect with the wheels. To
restart the engine when the vehicle
is already moving, use
N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
(Continued)
Caution (Continued)
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
Caution
The vehicle is not designed to
stay in N (Neutral) for extended
periods of time. It will
automatically shift into P (Park).
To shift into N (Neutral), press the
N (Neutral) switch on the front shift
console until the N (Neutral)
indicator displays.
To shift out of N (Neutral): 1. Bring the vehicle to a complete stop.
2. Shift to the desired gear.

210 Driving and Operating
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. SeeAntilock
Brake System (ABS) Warning Light
0 131. 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.

EPB switch. Continue to hold the
switch until the
Yor PARK 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.
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.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade sufficient enough to activate
HSA. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure for
a maximum of two seconds to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two-second
window. It 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). To
change the duration, see
“Extended
Hill Start Assist” inVehicle
Personalization 0142.

220 Driving and Operating
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.
With the Traction Control System
(TCS) or Electronic Stability Control
(ESC), the system may begin to
limit wheel spin while you are using
cruise control. If this happens, the
cruise control will automatically disengage. See
Traction Control/
Electronic Stability Control 0213.
If a collision alert occurs when
cruise control is activated, cruise
control is disengaged. See Forward
Collision Alert (FCA) System 0228.
When road conditions allow you to
safely use it again, cruise control
can be turned back on.
Cruise control will disengage if
either TCS or StabiliTrak is
turned off.
If Hill Descent Control (HDC) is
engaged, cruise control disengages.
See Hill Descent Control (HDC)
0 216.
If the brakes are applied, cruise
control disengages.
5: Press to turn the cruise control
system on and off. A white indicator
comes on in the instrument cluster
when cruise control is turned on.
*: Press to disengage cruise
control without erasing the set
speed from memory.
+RES : If there is a set speed in
memory, press briefly to resume that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
