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.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light 0129.
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 and 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

266 Driving and Operating
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 0314.
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 0230.
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
spinning wheels and reduces
engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the system senses a
discrepancy between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the direction
which you are steering.
If cruise control is being used
and traction control or
StabiliTrak/ESC begins to limit
wheel spin, cruise control willdisengage. 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
0241 and
“Turning the Systems Off and
On” later in this section.

Driving and Operating 271
If the Traction Control System
(TCS) or StabiliTrak/Electronic
Stability Control (ESC) begins
to limit wheel spin while using
cruise control, the cruise
control automatically
disengages. See Traction
Control/Electronic Stability
Control0267. If a collision
alert occurs when cruise
control is activated, cruise
control is disengaged. See
Forward Collision Alert (FCA)
System 0297. When road
conditions allow cruise control
to be safely used, it can be
turned back on.
Cruise control will disengage if
either TCS or StabiliTrak/ESC
is turned off.
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, move the
thumbwheel up briefly to
resume that speed or press
and hold to accelerate. If the
cruise control is already active,

2. Get up to the desiredspeed.
3. Move the thumbwheel down to 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 and a
cruise set speed message
appears on the Head-Up
Display (HUD), if equipped.
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, move the thumbwheel up toward RES+
briefly. The vehicle returns to
the previous set speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Move the thumbwheel up
toward RES+ until the
desired speed is reached,
then release it.
.To increase vehicle speed in
small increments, move the
thumbwheel up toward
RES+ briefly. For each press,
the vehicle goes about
1 km/h (1 mph) faster.
.To increase vehicle speed in
larger increments, move the
thumbwheel up toward
RES+ to the second detent.
For each press, the vehicle
speed increases to the next
5 km/h (5 mph) mark on the
speedometer.
The speedometer reading can
be displayed in either English
or metric units. See
Instrument Cluster
0119. The
increment value used depends
on the units displayed.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Move the thumbwheel down
toward SET− until the
desired lower speed is
reached, then release it.
.To decrease the vehicle
speed in small increments,
move the thumbwheel down
toward SET− briefly. For
each press, the vehicle goes
about 1 km/h (1 mph) slower.
.To decrease the vehicle
speed in larger increments,
move the thumbwheel down
toward SET− to the second
detent. For each press, the
vehicle speed decreases to
the next 5 km/h (5 mph) mark
on the speedometer.

274 Driving and Operating
Stability Control (ESC) system
activates, the ACC may
automatically disengage. See
Traction Control/Electronic
Stability Control0267. When
road conditions allow ACC to
be safely used, the ACC can
be turned back on.
Disabling the TCS or
StabiliTrak/ESC system will
disengage and prevent
engagement of ACC.
ACC can reduce the need for
you to frequently brake and
accelerate, especially when
used on expressways,
freeways, and interstate
highways. When used on other
roads, you may need to take
over the control of braking or
acceleration more often.
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.{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.
Also see “Alerting the
Driver” in this section.
Complete attention is
always required while driving
and you should be ready to
take action and apply the
brakes. See Defensive
Driving 0230.
{Warning
ACC will not detect or brake
for children, pedestrians,
animals, or other objects.
Do not use ACC when:
.On winding and hilly roads
or when the sensors are
blocked by snow, ice,
or dirt. The system may
not detect a vehicle
ahead. Keep the entire
front of the vehicle clean.
.Visibility is low, such as in
fog, rain, or snow
conditions. ACC
performance is limited
under these conditions.
.On slippery roads where
fast changes in tire
traction can cause
excessive wheel slip.
.When towing a trailer.

276 Driving and Operating
{Warning
Always check the cruise
control indicator on the
instrument cluster to
determine which mode
cruise control is in before
using the feature. If ACC is
not active, the vehicle will
not automatically brake for
other vehicles, which could
cause a crash if the brakes
are not applied manually.
You and others could be
seriously injured or killed.
Setting Adaptive Cruise
Control
If
Jis on when not in use, it
could get pressed and go into
cruise when not desired. Keep
Joff when cruise is not
being used.
Select the set speed desired
for cruise. This is the vehicle
speed when no vehicle is
detected in its path. ACC will not set at a speed
less than 25 km/h (15 mph),
although it can be resumed
when driving at lower speeds.
The minimum allowable set
speed is 25 km/h (15 mph).
To set ACC while moving:
1. Press
J.
2. Get up to the desired speed.
3. Press and release SET–.
4. Remove your foot from the accelerator.
After ACC is set, it may
immediately apply the brakes if
a vehicle ahead is detected
closer than the selected
following gap.
ACC can also be set while the
vehicle is stopped if ACC is on
and the brake pedal is applied. The ACC indicator displays on
the instrument cluster and
Head-Up Display (HUD),
if equipped. When ACC is
turned on, the indicator will be
lit white. When ACC is
engaged, the indicator will turn
green.
Be mindful of speed limits,
surrounding traffic speeds,
and weather conditions when
selecting the set speed.
Resuming a Set Speed
If the ACC is set at a desired
speed and then the brakes are
applied, ACC is disengaged
without erasing the set speed
from memory.
To begin using ACC again,
press RES+ up briefly.
.If the vehicle is moving more
than 5 km/h (3 mph), it
returns to the previous set
speed.
.If the vehicle is stopped with
the brake pedal applied,
press RES+ and release the

Driving and Operating 279
Without Head-Up Display
If ACC is engaged, driver
action may be required when
ACC cannot apply sufficient
braking because of
approaching a vehicle too
rapidly.
When this condition occurs,
the collision alert symbol will
flash on the windshield. Either
eight beeps will sound from
the front, or both sides of the
Safety Alert Seat will pulse
five times. Touch the Settings
icon on the infotainment home
page. Select “Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.
See Defensive Driving 0230. Approaching and Following a
Vehicle
The vehicle ahead indicator is
in the instrument cluster and
HUD display, if equipped.
The vehicle ahead indicator
only displays when a vehicle is
detected in your vehicle’s path
moving in the same direction.
If this symbol is not displaying,
ACC will not respond to or
brake for vehicles ahead.
ACC automatically slows the
vehicle down and adjusts
vehicle speed to follow the
vehicle in front at the selected
follow gap. The vehicle speed
increases or decreases to
follow the vehicle in front of
you, but will not exceed the
set speed. It may apply limited
braking, if necessary. When braking is active, the brake
lamps will come on. The
automatic braking may feel or
sound different than if the
brakes were applied manually.
This is normal.
Passing a Vehicle While
Using ACC
If the set speed is high
enough, and the left turn
signal is used to pass a vehicle
ahead in the selected
following gap, ACC may assist
by gradually accelerating the
vehicle prior to the lane
change.
{Warning
When using ACC to pass a
vehicle or perform a lane
change, the following
distance to the vehicle being
passed may be reduced.
ACC may not apply
sufficient acceleration or
braking when passing a
vehicle or performing a lane
