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
0128 and
Service Electric Parking Brake
Light 0128. 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

Driving and Operating 289
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 0365.
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.

alerts or warnings provided
by this system. Failure to

entrance or exit ramp.
Always be ready to use the
brakes if necessary.
{Warning
On curves, ACC may
respond to a vehicle in
another lane, or may not
have time to react to a
vehicle in your lane. You
could crash into a vehicle
ahead of you, or lose control
of your vehicle. Give extra
attention in curves and be
ready to use the brakes if
necessary. Select an
appropriate speed while
driving in curves.
ACC may operate differently
in a sharp curve. It may reduce
the vehicle speed if the curve
is too sharp. If equipped, the curve speed
control indicator
nmay
illuminate green when ACC is
actively controlling the vehicle
speed and detects a sharp
curve on the road ahead.
ACC automatically slows the
vehicle down while navigating
the curve and may increase
speed out of the curve, but will
not exceed the set speed.
When following a vehicle and
entering a curve, ACC may not
detect the vehicle ahead and
accelerate to the set speed.
When this happens, the
vehicle ahead indicator will not
appear.
ACC may detect a vehicle that
is not in your lane and apply
the brakes.
ACC may occasionally provide
an alert and/or braking that is
considered unnecessary.
It could respond to vehicles in
different lanes, signs,
guardrails, and other
stationary objects when
entering or exiting a curve.
This is normal operation. The
vehicle does not need service.
