SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake
performance under most braking conditions.
The system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this
self-check, you may hear a slight clicking sound
as well as some related motor noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS
activation(s).
You also may experience the following when
ABS activates:
The ABS motor noise (it may continue to run
for a short time after the stop)
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop
These are all normal characteristics of ABS.
ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires.
Modification may result in degraded ABS
performance.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter-
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead
to a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize
the user’s safety or the safety of others.

Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will
turn on when the ignition is placed in the ON/
RUN mode and may stay on for as long as four
seconds.
If the “Anti-Lock Brake Warning Light” remains
on or comes on while driving, it indicates that
the anti-lock portion of the brake system is not
functioning and that service is required.
However, the conventional brake system will
continue to operate normally if the “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the
brake system should be serviced as soon as
possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning Light”
does not come on when the ignition is placed in
the ON/RUN mode, have the light repaired as
soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This
system includes Electronic Brake Force
Distribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS), Electronic Stability Control (ESC), and Electronic
Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Ready
Alert Braking (RAB), and Rain Brake Support
(RBS).
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to
optimize the vehicle’s braking capability during
emergency braking maneuvers. The system
detects an emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum pressure
to the brakes. This can help reduce braking
distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To
receive the benefit of the system, you must
apply continuous braking pressure during the
stopping sequence (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.
Brake System Warning Light
The red “Brake System Warning Light” will turn
on when the ignition is placed in the ON/RUN
mode and may stay on for as long as four
seconds.
If the “Brake System Warning Light” remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the “Brake
System Warning Light” does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
WARNING!
The Brake Assist System (BAS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. BAS cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of
a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner,
which could jeopardize the user's safety or
the safety of others.

HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK or NEUTRAL. For
vehicles equipped with a manual transmis -
sion, if the clutch is pressed, HSA will remain
active.Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using your instrument cluster
display, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multimedia”
for further information.
For vehicles not equipped with an instrument
cluster display, perform the following steps:

1. Center the steering wheel (front wheels pointing straight forward).

2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC OFF” switch located in the lower switch bank below the climate control
four times within 20 seconds. The “ESC OFF
Indicator Light” should turn on and turn off
two times.WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA
is not a substitute for active driving
involvement. It is always the driver’s
responsibility to be attentive to distance to
other vehicles, people, and objects, and most
importantly brake operation to ensure safe
operation of the vehicle under all road
conditions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated
and deactivated with the brake switch. If
so, there may not be enough brake pres -
sure to hold both the vehicle and the trailer
on a hill when the brake pedal is released.
In order to avoid rolling down an incline
while resuming acceleration, manually acti -
vate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake
pedal.
HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.

your seat belt, and if present, instruct all other
occupants to buckle their seat belts.
MANUAL TRANSMISSION — IF EQUIPPED
Apply the parking brake, place the gear selector
in NEUTRAL and press the clutch pedal before
starting vehicle. This vehicle is equipped with a
clutch interlocking ignition system. It will not
start unless the clutch pedal is pressed to the
floor.
AUTOMATIC TRANSMISSION — IF
E
QUIPPED
The gear selector must be in the PARK position
before you can start the engine. Apply the
brakes before shifting into any driving gear.
Tip Start Feature — Automatic
Transmission
Place the ignition in the START mode and
release it as the starter engages. The starter
motor will automatically disengage itself once
engine is running.
WARNING!
When exiting the vehicle, always make sure
the ignition is in OFF mode, remove the key
fob from the vehicle and lock the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Leaving
children in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally
injured. Children should be warned not to
touch the parking brake, brake pedal or the
transmission gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition (of a
vehicle equipped with Keyless Enter-N-Go)
in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
WARNING! (Continued)
CAUTION!
Shift into or out of PARK or REVERSE only
after the vehicle has come to a complete
stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your foot is firmly pressing the brake pedal.

160STARTING AND OPERATING
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK SYSTEM
This vehicle is equipped with a Brake
Transmission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed.
The brake pedal must also be pressed to shift
from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds.
EIGHT-SPEED AUTOMATIC
T
RANSMISSION
The transmission gear range (PRNDM) is
displayed both on the gear selector and in the
instrument cluster.
To select a gear range, push the lock button on
the gear selector and move the selector
rearward or forward. To shift the transmission
out of PARK, the engine must be running and
the brake pedal must be pressed. You must
also press the brake pedal to shift from
NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds.
Select the DRIVE range for normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink continu
-
ously until the selector is returned to the proper
position, or the requested shift can be
completed.

Automatic Transmission Gear Selector

The electronically-controlled transmission
adapts its shift schedule based on driver inputs,
along with environmental and road conditions.
The transmission electronics are
self-calibrating; therefore, the first few shifts on
a new vehicle may be somewhat abrupt. This is
a normal condition, and precision shifts will
develop within a few hundred miles
(kilometers). Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, DRIVE, and MANUAL
(AutoStick) shift positions. Manual shifts can be
made using the AutoStick shift control. Toggling
the gear selector forward (-) or rearward (+)
while in the MANUAL (AutoStick) position
(beside the DRIVE position) will manually select
the transmission gear, and will display the
current gear in the instrument cluster as M1,
M2, M3, etc. Refer to "AutoStick" in this section
for further information.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the MANUAL
(AutoStick, +/-) position (beside the DRIVE posi
-
tion). In MANUAL (AutoStick) mode, the trans -
mission gear is displayed in the instrument
cluster (as M1, M2, M3, etc.). Move the gear
selector to the right (into the DRIVE [D] position)
for access to PARK, REVERSE, and NEUTRAL.

Cruise Control (ACC) system.
Adaptive Cruise Control Buttons

NOTE:
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward
Collision Warning system.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for two seconds in the stop
position. If the target vehicle does not
start moving within two seconds the
ACC system will display a message that
the system will release the brakes and
that the brakes must be applied manu -
ally. An audible chime will sound when
the brakes are released.
WARNING! (Continued)
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc -
tion zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.

174STARTING AND OPERATING
SETTING THE FOLLOWING DISTANCE IN
ACC
The specified following distance for ACC can be
set by varying the distance setting between four
bars (longest), three bars (long), two bars
(medium) and one bar (short). Using this
distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle
ahead. This distance setting will show in the
instrument cluster display.

Distance Settings
To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
instrument cluster display will show the ACC Set
With Target Light, and the system adjusts
vehicle speed automatically to maintain the
distance setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor
-
mation on ACC Activation). The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the
instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.

STARTING AND OPERATING175
NOTE:
The “BRAKE!” Screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
OVERTAKE AID
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal and will only be active when passing on
the left hand side.
ADAPTIVE CRUISE CONTROL (ACC)

depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off
button (located on the steering wheel) until one
of the following appears in the instrument
cluster display: Adaptive Cruise Control Off
When ACC is deactivated, the display will read
“Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed
setting has not been selected, the display will
read “Adaptive Cruise Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button (located
on the steering wheel) is pushed, the display will
read “ACC SET.”
When ACC is set, the set speed will show in the
instrument cluster display.
The ACC screen may display once again if any
ACC activity occurs, which may include any of
the following:System Cancel
Driver Override
System Off
ACC Proximity Warning
ACC Unavailable Warning
The instrument cluster display will return to the
last display selected after five seconds of no
ACC display activity
DISPLAY WARNINGS AND
M
AINTENANCE
“Wipe Front Radar Sensor In Front Of
Vehicle” Warning
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and also a chime
will indicate when conditions temporarily limit
system performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
“ACC/FCW Unavailable Wipe Front Radar
Sensor” and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e.
tunnels with reflective tiles, or ice and snow).
The ACC system will recover after the vehicle
has left these areas. Under rare conditions,
when the radar is not tracking any vehicles or
objects in its path this warning may temporarily
occur.

178STARTING AND OPERATING
Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you are
traveling. In the illustration shown, ACC has not
yet detected the vehicle changing lanes and it
may not detect the vehicle until it's too late for
the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane.
There may not be sufficient distance to the
lane-changing vehicle. Always be attentive and
ready to apply the brakes if necessary.

Lane Changing Example

Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.
Narrow Vehicle Example

Stationary Objects And Vehicles
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not
react in situations where the vehicle you are
following exits your lane and the vehicle ahead
is stopped in your lane. Always be attentive and
ready to apply the brakes if necessary.
