TheYor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light
flashes continuously, then the EPB
is only partially applied, the vehicle
is in Service Mode, or there is a
problem with the EPB. A Driver
Information Center (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
Yor
PARK light is flashing. See your
dealer. See Electric Parking Brake
Light 0145.
If the
8light is on or theYor
PARK light flashes when the ignition
is turned on, pull the EPB switch
and hold it. Continue to hold the
switch until the
Yor PARK light
remains on. If the
8light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is pulled. If the switch is pulled 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.
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 ACC/ ACCESSORY.
2. Apply and hold the brake pedal.

240 Driving and Operating
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)
Hill Start Assist (HSA) will activate
when the vehicle is stopped on a
moderate to steep grade to help
prevent it from rolling in an
unintended direction. After the brake
pedal has been released and before
the accelerator pedal has been
pressed, HSA uses braking
pressure to hold the vehicle
stationary. If HSA is holding the
vehicle, a DIC message displays.
HSA will not activate in a forward
drive gear when facing downhill,
or in R (Reverse) when facing uphill.
Select the duration of the HSA
feature through vehicle
personalization. See”Extended Hill
Start Assist” under“Comfort and
Convenience” inVehicle
Personalization 0155. When
Standard Hold is selected, the
vehicle is held stationary for up to
two seconds after the brake pedal is
released. When Extended Hold is
selected, the vehicle is held
stationary for up to five minutes
after the brake pedal is released. In either case, override the hold
feature by pressing the accelerator
pedal and attempting to drive away.
If Standard Hold is selected, it will
hold the vehicle for two seconds
unless the driver door is opened or
the driver seat belt is unbuckled
after releasing the brake pedal.
If Extended Hold is selected, it will
hold the vehicle for five minutes
unless the driver door is opened
and the driver seat belt is unbuckled
prior to releasing the brake pedal.
When deactivated after five minutes,
or if it is deactivated when the driver
seat belt is unlatched or the driver
door is opened, the Electric Parking
Brake will engage to prevent vehicle
movement.

Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC),
an electronic stability control
system. 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 spinning 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/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will automatically
turn on when cruise control is set.
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 0220
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/ESC 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.
If
dcomes on and stays on:
1. Stop the vehicle.

Cruise Control
{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 cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph). If the Traction Control System (TCS)
or StabiliTrak/Electronic Stability
Control (ESC) system begins to limit
wheel spin while using cruise
control, the cruise control
automatically disengages. See
Traction Control/Electronic Stability
Control
0241. If a collision alert
occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0261. When
road conditions allow the cruise
control to be safely used, cruise
control can be turned back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage the
cruise control.
If the brakes are applied, cruise
control disengages.
J: Press to turn the system on
and off. A white indicator appears in
the instrument cluster when cruise
is turned on.
RES+ : If there is a set speed in
memory, press briefly to resume to
that speed or press and hold to
accelerate. If the cruise control is
already active, use to increase
vehicle speed.
SET− :Press briefly to set the
speed and activate cruise control.
If the cruise control is already
active, use to decrease vehicle
speed.

Jis on when not in use, SET− or
RES+ could get pressed and go into
cruise when not desired. Keep
J
off when cruise is not being used.
1. Press
J.
2. Get up to the desired speed.
3. Press and release SET−. The desired set speed briefly
appears in the instrument
cluster.
4. Remove your foot from the accelerator.
When the cruise control has been
set to the desired speed, a green
cruise control indicator appears on
the instrument cluster. Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or
*is pressed, the
cruise control is disengaged without
erasing the set speed from memory.
Once the vehicle speed reaches
about 40 km/h (25 mph) or more,
press RES+ briefly. The vehicle
returns to the previous set speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Press and hold RES+ up until
the desired speed is reached,
then release it.
. To increase vehicle speed in
small increments, briefly press
RES+. For each press, the
vehicle goes about 1 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0135.
The increment value used depends
on the units displayed. Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.
Press and hold SET− until the
desired lower speed is reached,
then release it.
. To decrease the vehicle speed in
small increments, briefly press
SET−. For each press, the
vehicle goes about 1 km/h
(1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0135.
The increment value used depends
on the units displayed.
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 will slow down to the
previous set cruise speed.

12146157) - 2019 - CRC - 10/31/18
248 Driving and Operating
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly applying
SET−will result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work
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 your
speed. While on a hill, the
transmission may downshift in order
to use engine braking to slow the
vehicle and maintain the set speed.
Also, you may have to brake or shift
to a lower gear to keep your speed
down. If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are four ways to end cruise
control:
. Step lightly on the brake pedal.
. Press
*. .
Shift the transmission to
N (Neutral).
. Press
J.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path, moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See Radio
Frequency Statement 0399.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control (ESC)
system activates, the ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control
0241. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage the
cruise control.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
