and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toWarning lights and
chimesin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an anti-lock braking system (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled and
the ABS light is on, normal braking
is still effective. If your BRAKE
warning lamp illuminates with the
parking brake released, have your
brake system serviced immediately.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance and does not
decrease the time necessary to apply the brakes.

Regenerative Braking System (RBS)
Your vehicle uses a feature known as regenerative braking. This is used
to simulate the engine braking of an internal combustion engine and
assist the standard brake system while recovering some of the energy of
motion and storing it in the battery to improve fuel economy. The
standard brake system is designed to fully stop the car if regenerative
braking is not available. During regenerative braking, the motor is spun
as a generator to create electrical current. This recharges the high
voltage battery and slows the vehicle. In effect, once the accelerator
pedal is released, the motor changes from an energy user to an energy
producer.
When the accelerator pedal is released or the brake pedal is applied, the
brake controller automatically detects the amount of deceleration
requested and optimizes how much of the deceleration will be produced
by regenerative braking. The remaining portion is generated by standard
friction braking. When the battery is almost fully charged, the amount of
regenerative braking is limited to avoid overcharging, and the requested
deceleration is produced by standard friction braking alone.
Regenerative braking does not take the place of the standard friction
brakes; it only assists them. Regenerative braking has also been designed
to interact with the anti-lock brake system (ABS). Regenerative braking
is disabled when the ABS is activated or the battery is fully charged.
Parking brake
To set the parking brake (1), pull
the parking brake handle up as far
as possible.
The BRAKE warning lamp will
illuminate and will remain
illuminated until the parking brake
is released.
To release, press and hold the button (2), pull the handle up slightly,
then push the handle down.

WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily, and you may hear a chime. If equipped with a message center,
the vehicle will also indicate a failure with the brake system. Have the
system serviced by an authorized dealer immediately.
The AdvanceTracsystem automatically enables each time the engine is
started. All features of the AdvanceTracsystem (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTracsystem includes
one of these stability control
switches located on the instrument
panel.
The stability control light and the
stability control off light located in
the instrument cluster will
illuminate temporarily during
start-up as part of a normal system self-check. The stability control light
may illuminate (flash) during certain driving situations which cause the
AdvanceTracsystem to operate. If the stability control light illuminates
steadily, have the system serviced by an authorized dealer immediately. If
equipped with a message center, the vehicle will also indicate a failure
with the AdvanceTracsystem.
When AdvanceTracperforms a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracyou may experience
the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•If your foot is on the brake pedal, a vibration in the pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.

Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem; engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
During TCS events, the stability control light in the instrument cluster
will flash.
If TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, TCS will use only engine power
reduction or transfer to help control the wheels from over-spinning.
When the brakes have cooled down, the system will regain all features.
Anti-lock braking and electronic stability control (ESC) will continue to
function during the cool-down period.
The engine traction control and brake traction control systems may be
deactivated in certain situations. See theSwitching off AdvanceTrac
section below.
Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate ESC, which include but
are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa

Switching off AdvanceTrac
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracsystem may be
beneficial because the wheels are allowed to spin. This will restore full
engine power and will enhance momentum through the obstacle.
To turn off the traction control
system, press the stability control
off switch. The off switch could look
like either of the two graphics
shown. Full features of the
AdvanceTracsystem can be
restored by pressing the switch
again or by turning off and
restarting the engine.
When the traction control system is
off, the stability control off light will
illuminate steadily. Pressing the
stability control switch again will
turn off the stability control off
light.
In R (Reverse), ABS and the engine and brake traction control features
will continue to function; however, ESC is disabled.

STEERING
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin theDriver
Controlschapter for more information.
WARNING:The EPS system has diagnostics checks that
continuously monitor the EPS system to ensure proper operation
of the electronic system. When an electronic error is detected, the
message POWER STEERING ASSIST FAULT will be displayed in the
message center. If this happens, stop the vehicle in a safe place, and
turn off the engine. After at least 10 seconds, reset the system by
restarting the engine, and watch the message center for POWER
STEERING ASSIST FAULT. If the message returns, or returns while
driving, take the vehicle to your dealer to have it checked. With the
message displayed, the steering assist is turned off, making the vehicle
harder to steer.
WARNING:If the message SERVICE POWER STEERING is
displayed in the message center, the EPS system has detected a
problem with the system function. On the next key cycle the message
SERVICE POWER STEERING NOW will be displayed and steering
assist will be removed until the steering system is serviced. Have your
vehicle taken to the nearest dealer as soon as possible.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear

REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the RSS.

WARNING:Objects in the blind spot mirror are closer than they
appear.
BLIND SPOT INFORMATION SYSTEM (BLIS) WITH CROSS
TRAFFIC ALERT (CTA) (IF EQUIPPED)
The BLISis a convenience feature
that aids the driver in assessing
whether a vehicle is within an area
on either side of the vehicle
extending rearward from the outside
mirrors to approximately 10 feet
(three meters) beyond the bumper.
This area is referred to as the blind
zone. The BLISwill alert the driver
to the presence of motorized
vehicles in these areas while driving
on roads and freeways.
The system is not designed to
prevent contact with other vehicles
or objects. The system is designed
to provide a warning to assist the
driver in detecting vehicles in the blind zones. The system will not detect
infrastructure, pedestrians, or cyclists.
WARNING:To help avoid injuries, NEVER use the BLISas a
replacement for using the side and rear view mirrors and looking
over your shoulder before changing lanes. BLISis not a replacement
for careful driving and only an assist.
The BLIShas an yellow indicator
(also referred to as the alert)
located in the left and right exterior
mirrors. When the vehicle is started,
the BLISautomatically illuminates
both indicators for several seconds
indicating the system is operating.
The first time you place the
transmission in D (Drive) after starting the engine and drive forward at a
speed greater than 3 mph (5 km/h) the BLISbecomes active.

Day and night brightness
The BLIS-CTA alert will automatically dim when the headlamp switch is
in the parking, on, or autolamp position, and night time darkness has
been detected by the sun sensor.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.
