ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system that
includes the Brake Assist System (BAS), Crosswind
Assist (CWA), Electronic Stability Control (ESC), Hill
Start Assist (HSA), Traction Control System (TCS),
and Trailer Sway Control (TSC). These systems
complement the Anti-Lock Brake System (ABS) by
optimizing the vehicle braking capability during
emergency braking maneuvers.
Brake Assist System (BAS)

The 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.
Crosswind Assist (CWA)

CWA helps keep your vehicle from drifting out of its lane
due to unexpected crosswinds by means of targeted
braking of individual wheels. The system will provide
automatic stability assistance to counteract the effect
of strong side wind. If a strong lateral wind is detected,
front and rear brakes on the affected side are applied,
creating a steering effect that mitigates the crosswind
influence. During system intervention, the driver should
perceive the natural stable handling feel of the vehicle.

Crosswind Assist will activate automatically when
the vehicle reaches speeds above approximately
43 mph (70 km/h). When the system is activated,
the ESC Warning Light in the instrument cluster will
blink to warn the driver.
Electronic Roll Mitigation (ERM)
The ERM system anticipates the potential for
wheel lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When ERM
determines that the rate of change of the steering
wheel angle and vehicle’s speed are sufficient to
potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine
power to lessen the chance that wheel lift will
occur. ERM can only reduce the chance of wheel
lift occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due to
other factors, such as road conditions, leaving the
roadway, striking objects or other vehicles.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.

WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may occur.
ERM cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.

154SAFETY
Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for over/under steering of the vehicle by
applying the brake of the appropriate wheel(s) to
counteract the previous conditions listed. Engine
power may also be reduced to help the vehicle
maintain the desired path.
Oversteer – when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer – when the vehicle is turning less
than appropriate for the steering wheel position.

ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC applies
the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition.

ESC Operating Modes
The ESC OFF button is located in the
center switch bank, next to the hazard
flasher switch.
ESC On
This mode is the normal operating mode for
ESC equipped vehicles. Whenever the vehicle is
started, the ESC system will be in this mode. This
mode should be used for most driving situations.
ESC should only be turned off for the following
specific reasons.
ESC Partial Off
This mode is entered by momentarily pushing the
ESC OFF button.
When in the “Partial Off” mode, the TCS portion of
ESC, except for the “limited slip” feature described
in the TCS section, has been disabled and the ESC
OFF Indicator Light will be illuminated. When in the
“Partial Off” mode, ESC will operate without engine
torque management. This mode is intended to be
used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESC would
normally allow is required to gain traction. To turn
ESC on again, momentarily push the ESC OFF
button. This will restore the normal “ESC On” mode
of operation.WARNING!

Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent
accidents, including those resulting from exces -
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the
conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user’s safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.

SAFETY157
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and apply
the brake of the appropriate wheel(s) to counteract
the sway of the trailer.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer
tongue weight recommendations
Ú
page 124.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced, and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
DROWSY DRIVER DETECTION (DDD) —
IF EQUIPPED
DDD detects when the driver is feeling fatigued
and warns the driver to pull over and take a break.
TO ACTIVATE/DEACTIVATE

DDD can be activated and deactivated through the
Uconnect system by selecting the following in order:

1. “Safety & Driving Assistance”

2. “Drowsy Driver Detection”
SYSTEM OPERATION
Using feedback obtained from the driver’s steering
patterns, any buttons/switches that are pressed,
and from the front camera, the system implements
two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 100 mph
(160 km/h).
WARNING!
The TCS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded.
The TCS cannot prevent collisions, including
those resulting from excessive speed in turns,
or hydroplaning.
The capabilities of a TCS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
WARNING!
The DDD system is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. Always drive alert and get
plenty of rest before driving. If you experience
fatigue while driving, do not wait for the DDD to
intervene with a warning. Choose a safe and
secure location where you can pull over safely
for a break. Only return to the road when you are
in the right physical and mental condition to
prevent endangering yourself and others.

SUPPLEMENTAL RESTRAINT
S
YSTEMS (S RS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC)
monitors the internal circuits and interconnecting
wiring associated with the electrical Air Bag System
Components. Your vehicle may be equipped with the
following Air Bag System Components:

Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the AVV (START) or
MAR (ACC/ON/RUN) position. If the ignition switch
is in the STOP (OFF/LOCK) position the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
in the MAR (ACC/ON/RUN) position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR (ACC/ON/RUN)
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled.
In this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have the
air bag system to protect you in a collision. If the
light does not come on as a bulb check when the
ignition is first turned on, stays on after you start
the vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag system
immediately.

Air Bag System Components
NOTE:The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring
associated with electrical Air Bag System Compo -
nents listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all colli -
sions. This does not mean something is wrong with
the air bag system. If you do have a collision which deploys the air
bags, any or all of the following may occur:

The air bag material may sometimes cause abra
-
sions and/or skin reddening to the occupants as
the air bags deploy and unfold. The abrasions are
similar to friction rope burns or those you might get
sliding along a carpet or gymnasium floor. They are
not caused by contact with chemicals. They are not
permanent and normally heal quickly. However, if
you haven’t healed significantly within a few days,
or if you have any blistering, see your doctor
immediately.

As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles
settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.
NOTE:

Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.

After any collision, the vehicle should be taken
to an authorized dealer immediately.
Fuel Cut Off Switch
Your vehicle is equipped with a Fuel Cut Off switch.
In the event of an accident, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Fuel Cut Off Switch may perform the following
functions:
Cut off fuel to the engine and turn off the
engine.
Flash hazard lights as long as the battery has
power or until the hazard light button is pressed.
The hazard lights can be deactivated by
pressing the hazard light button.
WARNING!

Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the air
bags, seat belt pretensioners, and the seat belt
retractor assemblies replaced by an authorized
dealer immediately. Also, have the Occupant
Restraint Controller System serviced as well.

Turn on the interior lights, which remain on as
long as the battery has power.
Unlock the power door locks.
NOTE:After an accident, remember to cycle the ignition
to the STOP (OFF/LOCK) position and remove the
key from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the Fuel Cut Off Switch by following
the procedure described below. If you have any
doubt, contact an authorized dealer.
Fuel Cut Off Switch Reset Procedure
In order to reset the Fuel Cut Off Switch after an
event push the “A” Button located underneath the
front passenger side instrument panel.

Maintaining Your Air Bag System
WARNING!
If, after an accident, you smell fuel or see leaks
from the fuel system, do not reset the Fuel Cut
Off Switch to avoid the risk of fire. Before
resetting the Fuel Cut Off Switch, carefully check
for fuel leaks or damage to the vehicle electrical
devices (e.g. headlights).
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.

Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any air
bag system service. If your seat, including your trim
cover and cushion, needs to be serviced in any way
(including removal or loosening/tightening of seat
attachment bolts), take the vehicle to an authorized
dealer. Only manufacturer approved seat accesso -
ries may be used. If it is necessary to modify the air
bag system for persons with disabilities, contact an
authorized dealer.

IN CASE OF EMERGENCY207
If the tire inflates to the recommended pressure or
is at least 26 psi (1.8 bar) within 15 minutes:
NOTE:If the tire becomes overinflated, push the Deflation
Button to reduce the tire pressure to the recom -
mended inflation pressure before continuing.

1. Push the Power Button to turn the Tire
Service Kit off.

2. Remove the speed limit label from the
Tire Service Kit and place sticker on the
steering wheel.
3. Immediately disconnect the Sealant Hose from the valve stem, reinstall the cap on the
fitting at the end of the hose, and place the Tire
Service Kit in the vehicle storage location.
Drive Vehicle: Immediately after injecting sealant
and inflating the tire, drive the vehicle
5 miles (8 km) or 10 minutes to ensure distribution of the Tire Service Kit Sealant
within the tire. Do not exceed 50 mph (80 km/h). After Driving:
Pull over to a safe location and turn on the
vehicle’s Hazard Warning Flashers.
Verify that the valve stem (on the wheel with
the deflated tire) is in a position that is near to
the ground. This will allow the Tire Service Kit
Hose to reach the valve stem and keep the Tire
Service Kit flat on the ground. This will provide
the best positioning of the kit when injecting the
sealant into the deflated tire and running the
air pump. Move the vehicle as necessary to
place the valve stem in this position before
proceeding.
Place the transmission in PARK (P) and cycle the
ignition in the OFF position.
Apply the parking brake.
NOTE:
If tire has improper inflation follow these next steps:

1. Uncoil the Sealant Hose, and then remove the
cap from the fitting at the end of the hose.

2. Place the Tire Service Kit flat on the
ground next to the deflated tire.
3. Remove the cap from the valve stem, and then screw the fitting at the end of the Sealant Hose
onto the valve stem.
4. Uncoil the Power Plug and insert the
plug into the vehicle's 12 Volt power
outlet.
5. Uncoil the Hose and screw the fitting at
the end of the hose onto the valve stem.
6. Turn the Mode Select Knob and turn to
the Air Mode position.
7. Check the pressure in the tire by reading the Pressure Gauge.
If tire pressure is less than 19 psi (1.3 bar):
The tire is too badly damaged. Do not attempt to
drive the vehicle further. Call for assistance.WARNING!

The Tire Service Kit is not a permanent flat tire
repair. Have the tire inspected and repaired or
replaced after using the Tire Service Kit. Do not
exceed 50 mph (80 km/h) until the tire is repaired
or replaced. Failure to follow this warning can result
in injuries that are serious or fatal to you, your
passengers, and others around you. Have the tire
checked as soon as possible at an authorized dealer.
