RADIO OPERATION AND MOBILE PHONES

Under certain conditions, the mobile phone being

performance from your radio. This condition may

be lessened or eliminated by repositioning the

mobile phone within the vehicle. This condition is

does not satisfactorily improve from repositioning

the mobile phone, it is recommended that the

volume be turned down or off during mobile phone

operation when not using the Uconnect system.

YSTEM

(ABS)

The 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.
The ABS is activated during braking when the

system detects one or more wheels are beginning

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 normal

characteristics when the ABS activates:



ABS motor noise or clicking sounds (you may

continue to hear for a short time after the stop)



Brake pedal pulsations



A slight drop of the brake pedal at the end of the

stop

The ABS is designed to function with the Original

Equipment Manufacturer (OEM) tires. Modification

may result in degraded ABS performance.

Anti-Lock Brake System (ABS) Warning

Light

The yellow ABS 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 ABS 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 ABS Warning Light is on.

WARNING!



The ABS contains sophisticated electronic

equipment that may be susceptible to interfer

ence 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 qual

ified 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 hydro

planing.



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.

WARNING!

SAFETY

249

If the ABS Warning Light is on, the brake system

should be serviced as soon as possible to restore

the benefits of Anti-Lock Brakes. If the ABS

Warning Light does not come on when the ignition

is placed in the ON/RUN mode, have the light

repaired as soon as possible.

ROWSY

RIVER

ETECTION

(DDD) —

QUIPPED

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).

If the driving style indicates that the driver is

unable to follow the road trajectory and respect the

horizontal lane markings while within the operating

speed range of the system, a pop up will display on

the instrument cluster display to suggest that the

driver should stop for a break. An audible signal

will also sound.
If the driver accepts the suggestion provided by the

system by pushing the “OK” button on the left side

of the steering wheel, the message will disappear

from the display.
If the driver does not acknowledge the warning, it

will be displayed for 60 seconds and then

disappear.

NOTE:

In the event of a DDD system failure, a dedicated

message will appear in the instrument cluster

display.

DDD Warning Message

EAR

LERT

(RSRA)

RSRA alerts you through a visual and auditory

notification of the possible presence of an object,

passenger, or pet in the rear seats if a rear door

was opened up to 10 minutes before the ignition

was placed in the ON/RUN position. RSRA does not

directly detect objects, passengers, or pets in the

rear seats. When the previous conditions are met,

RSRA displays the message “Check Rear Seat” on

the instrument cluster display and sounds an

auditory alert upon the driver placing the ignition in

the OFF position to exit the vehicle.
To enable or disable RSRA, see

page 204.

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

If applicable, refer to the “Hybrid Supplement” for

additional information.
Your vehicle is equipped with an advanced EBC

system. This system includes the Anti-Lock Brake

System (ABS), Brake Assist System (BAS),

Electronic Brake Force Distribution (EBD),

Electronic Roll Mitigation (ERM), Electronic

Stability Control (ESC), Hill Start Assist (HSA), and

Traction Control System (TCS). These systems work

together to enhance both vehicle stability and

control in various driving conditions.
Your vehicle may also be equipped with Dynamic

Steering Torque (DST), Rain Brake Support (RBS),

Ready Alert Braking (RAB), and Trailer Sway

Control (TSC).

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.

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!



Before exiting a vehicle, always come to a

complete stop, then shift the automatic trans

mission into PARK and apply the parking

brake.



Always make sure the keyless ignition node is

in the OFF position, key fob is removed from

the vehicle and vehicle is locked.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Leaving chil

dren 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 gear selector.



Do not leave children or animals inside parked

vehicles in hot weather. Interior heat buildup

may cause serious injury or death.

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.

Electronic Brake Force Distribution (EBD)

EBD manages the distribution of the braking

torque between the front and rear axles by limiting

braking pressure to the rear axle. This is done to

prevent overslip of the rear wheels to avoid vehicle

instability, and to prevent the rear axle from

entering ABS before the front axle.

Electronic Roll Mitigation (ERM)

ERM 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, or striking

objects or other vehicles.
NOTE:

ERM is disabled any time the ESC is in “Full Off”

mode (if equipped). See

page 251 for a

complete explanation of the available ESC modes.

Electronic Stability Control (ESC)

ESC enhances directional control and stability of

the vehicle under various driving conditions. ESC

corrects for oversteering or understeering of the

vehicle by applying the brake of the appropriate

wheel(s) to assist in counteracting the following

conditions. 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.
The ESC Activation/Malfunction Indicator Light

located in the instrument cluster will start to flash

as soon as the ESC system becomes active. The

ESC Activation/Malfunction Indicator Light also

flashes when the Traction Control System (TCS) is

active. If the ESC Activation/Malfunction Indicator

Light begins to flash during acceleration, ease up

on the accelerator and apply as little throttle as

possible. Be sure to adapt your speed and driving

to the prevailing road conditions.

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.
