274 Driving and Operating
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light0138.
ABS does not change the time
needed to get a foot on the
brake pedal and does not
always decrease stopping
distance. If you get too close
to the vehicle ahead, there will
not be enough time to apply
the brakes if that vehicle
suddenly slows or stops.
Always leave enough room
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just
hold the brake pedal down
firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and
braking at the same time. In
many emergencies, steering
can help even more than
braking.
Electric Parking Brake
The Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is off. In
case of insufficient electrical
power, the EPB cannot be
applied or released. To
prevent draining the battery,
avoid unnecessary repeated
cycles of the EPB.
The system has a red parking
brake status light and an
amber service parking brake
warning light. See Electric
Parking Brake Light 0137 and Service Electric Parking Brake
Light
0137. There are also
parking brake-related Driver
Information Center (DIC)
messages.
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.
If the amber service parking
brake warning light is on,
press the EPB switch.
Continue to hold the switch
until the red parking brake
status light remains on. If the
amber service 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 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, or at the request
of other safety functions that
utilize the EPB.If the EPB fails to apply, block
the rear wheels to prevent
vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
red parking brake status light
is off.
If the amber service parking
brake warning light is on,
release the EPB by pressing
and holding the EPB switch.
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.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing
Tips 0347.
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.

276 Driving and Operating
Brake Assist
Brake Assist detects rapid
brake pedal applications due
to emergency braking
situations and provides
additional braking to activate
the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to
activate ABS normally. Minor
noise, brake pedal pulsation,
and/or pedal movement during
this time may occur. Continue
to apply the brake pedal as
the driving situation dictates.
Brake Assist disengages when
the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA
feature. HSA does not
replace the need to pay
attention and drive safely.
You may not hear or feel
alerts or warnings provided
by this system. Failure to(Continued)
Warning (Continued)
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving 0240.
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) prevents the vehicle
from rolling in an unintended
direction during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will
apply. The brakes may also
release under other
conditions. Do not rely on HSA
to hold the vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel spin 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. On an All-Wheel Drive
(AWD) vehicle in AWD or Sport
Mode, the system will operate
if it senses that any of the
wheels are spinning or
beginning to lose traction.
When this happens, TCS
applies the brakes to the

Backing Warning and
Reverse Automatic
Braking (RAB)
If equipped, vehicles with
Adaptive Cruise Control (ACC)
have the Backing Warning
System and Reverse
Automatic Braking (RAB)
system. When in R (Reverse),
Backing Warning alerts of rear
objects at vehicle speeds
greater than 8 km/h (5 mph),
and RAB may automatically
brake hard at speeds between
1–32 km/h (0.5–20 mph).
The Backing Warning System
will beep once from the rear
when an object is first

detected, or pulse twice on
both sides of the Safety Alert
Seat. When the system
detects a potential crash,
beeps will be heard from the
rear, or five pulses will be felt
on both sides of the Safety
Alert Seat. There may also be
a brief, sharp application of
the brakes.
{Warning
The Backing Warning
System only operates at
speeds greater than 8 km/h
(5 mph). It does not detect
children, pedestrians,
bicyclists, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. In some
situations, such as at higher
backing speeds, there may
not be enough time for the
short, sharp application of
the vehicle brake system to
occur. To prevent injury,
death, or vehicle damage,(Continued)
Warning (Continued)
even with the Backing
Warning System, always
check the area around the
vehicle and check all mirrors
before backing.
When the vehicle is in
R (Reverse), if the system
detects the vehicle is backing
too fast to avoid a crash with
a detected object behind your
vehicle in your path, it may
automatically brake hard to a
stop to help avoid or reduce
the harm caused by a backing
crash.
{Warning
RAB may not avoid many
types of backing crashes. Do
not wait for the automatic
braking to apply. This
system is not designed to
replace driver braking and
only works in R (Reverse)
when an object is detected (Continued)
Warning (Continued)
directly behind the vehicle.
It may not brake or stop in
time to avoid a crash. It will
not brake for objects when
the vehicle is moving at very
low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. To prevent
injury, death, or vehicle
damage, even with RAB,
always check the area
around the vehicle before
and while backing.
Pressing the brake pedal after
the vehicle comes to a stop
will release RAB. If the brake
pedal is not pressed soon
after the stop, the Electric
Parking Brake (EPB) may be
set. When it is safe, press the
accelerator pedal firmly at any
time to override RAB.
