9-30 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When propulsion is active and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
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
on page 5-22. 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 that 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
the driver 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 might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch is on the
center stack. The EPB can always
be activated, even if the vehicle is
off. To prevent draining the 12-volt
battery, avoid repeated cycles
of the EPB system when the vehicle
is off.The system has a red parking brake
status light and an amber parking
brake warning light. See
Electric
Parking Brake Light on page 5-22
and Service Electric Parking Brake
Light on page 5-22. There are also
parking brake-related Driver
Information Center (DIC) messages.
See Brake System Messages on
page 5-46. 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. Pull 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 on page 5-22.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on,
see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.

9-32 Driving and Operating
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, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the vehicle in ON/RUN.
2. Apply and hold the brake pedal.
3. Push momentarily on the EPBswitch.
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.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency. The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. The controller
interprets the braking request and
uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor‐driven
pump when it recharges the system.
This is normal.
See
Warning Lights, Gauges, and
Indicators on page 5-8 andDriver
Information Center (DIC) on
page 5-43. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.

Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and an Electronic
Stability Control system called
StabiliTrak. 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 slipping 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 of thevehicle wheel brakes to help 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 on
page 9-11 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.

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 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. 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 on
page 9-33. If a collision alert occurs
when cruise control is activated,
cruise control is disengaged. See
Forward Collision Alert (FCA)
System on page 9-38. When road
conditions allow you to safely use it
again, the cruise control can be
turned back on.
If the brakes are applied, the cruise
control shuts off.

*(Cancel): Press to disengage
cruise control without erasing the
set speed from memory.
RES/+ (Resume/Accel): Move the
thumbwheel up briefly to make the
vehicle resume to a previously set
speed or hold upwards to
accelerate. If cruise control is
already active, use to increase
vehicle speed. SET/−
(Set/Coast): Move the
thumbwheel down briefly to set the
speed and activate cruise control.
If cruise control is already active,
use to decrease speed.
Setting Cruise Control
If the cruise button is on when not in
use, it could get bumped and go into
cruise when not desired. Keep the
cruise control button off when cruise
is not being used.
To set a speed:
1. Press the
1button to turn the
cruise system on.
2. Get up to the speed desired.
3. Move the thumbwheel toward SET/− and release it. The
desired set speed briefly
appears in the instrument
cluster.
4. Remove foot from the accelerator pedal. Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied, 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
vehicle accelerates to the
desired speed, then release it.
.To increase the speed in small
increments, move the
thumbwheel up toward RES/+
briefly and then release it. Each
time this is done, the vehicle
goes about 1 km/h (1 mph)
faster.

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 slow down in small
increments, move the
thumbwheel toward SET/−
briefly. Each time this is done,
the vehicle goes about 1 km/h
(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the previously set cruise control speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
moving the thumbwheel toward
SET–
will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
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 the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied the cruise control is
disengaged. Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
.Press*.
.Press1to turn the cruise
control system off completely.
Erasing Speed Memory
The cruise control set speed is
erased from memory if

When the vehicle is in N (Neutral),
the system may be active. The
Parking Assist system may need to
be turned off during a car wash to
avoid repeating alerts. See“Turning
the System On and Off” later in this
section to turn the system off.
For vehicles with UFRPA,
high-toned beeps from the front
speakers are for objects detected
near the front bumper. Low-toned
beeps from the rear speakers are
for objects detected near the rear
bumper. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
Objects Detected by Both the
Front and Rear Sensors (If
Equipped)
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up, the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then the beeps only sound
to indicate the object that is closer
to the front bumper.
Turning the System On and Off
The system can be turned on and
off by pressing the park assist
button in the overhead console.
The indicator light next to the park
assist button lights up when the
system is active.When the system is turned off or
when there is a temporary condition
causing the system to be disabled,
PARK ASSIST OFF displays on the
Driver Information Center (DIC). The
message disappears after a short
period of time.
The system defaults to the on
setting each time the vehicle is
started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:

How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
the
@LANE DEPART button on the
steering wheel. The control indicator
will light when LDW is on.
When the vehicle is started, the
LDW indicator on the instrument
panel will come on briefly. If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while the
vehicle is traveling 56 km/h (35 mph)
or greater. If the vehicle crosses a
detected lane marking without using
the turn signal, this indicator will
change to amber and flash. In
addition, three beeps will be
sounded from the left or right side,
depending on the lane departure
direction.
When the System Does Not
Seem To Work Properly
If the LDW symbol does not appear
when the system is on and the
vehicle is traveling at least 56 km/h
(35 mph):
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{Warning
LDW does not provide a warning
to help avoid a crash, unless it
detects the lane markings. LDW
may not detect the lane markings
if the camera sensor is blocked
by dirt, snow, or ice, or if the
windshield is damaged. It may (Continued)
