216 Driving and Operating
Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is
pressed during the tests or
when the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
ABS performs a system check
when the vehicle is first driven.
A momentary motor or clicking
noise may be heard while this
test is going on, and the brake
pedal may move slightly. This
is normal.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light0117. 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.

Driving and Operating 217
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 Light0116 and Service Electric Parking Brake
Light
0116. 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.

218 Driving and Operating
If the EPB fails to apply, block
the rear wheels to prevent
vehicle movement.
EPB Release
To release the EPB:1. Turn the vehicle on.
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.
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
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
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving
0196.
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) prevents the vehicle

Driving and Operating 219
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.
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.Automatic Vehicle
Hold (AVH)
{Warning
Do not rely on this feature.
It 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 use proper care
when driving may result in
injury, death, or vehicle
damage.When Automatic Vehicle Hold
(AVH) is turned on and the
vehicle is braked to a stop,
AVH prevents the vehicle from
moving during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on AVH to hold the
vehicle.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will
apply. The parking brake will
also apply if the driver door is
opened or the driver seat belt
is unfastened while AVH is
holding the vehicle.
AVH can be turned on by
pressing AUTO HOLD. The
AVH indicator will come on.
While AVH is holding the
vehicle, the AVH indicator will
change to green. See
