Wide box trailers, especially those

wider than the towing vehicle, could

cause false alerts to occur when driving

next to infrastructure or near parked

cars. A false alert could also occur

while making a 90-degree turn or

driving through a roundabout.

System Operation

If you select a trailer in the information

display prior to connecting a trailer, the

system loads that configuration and the

information display shows a message

when you connect the trailer. A second

message appears stating cross traffic alert

is off, unless a trailer is set up with a length

of 3 ft (1 m). The blind spot information

system with trailer tow still functions

normally when driving forward.

•

Wide trailers that have a total length

greater than 20 ft (6 m) could cause

delayed alerts when a vehicle is

passing at high speeds.

Uneven tire wear.

WARNING: The electric power

steering system has diagnostic checks

that continuously monitor the system. If

a fault is detected, a message displays

in the information display. Stop your

vehicle as soon as it is safe to do so.

Switch the ignition off. After at least 10

seconds, switch the ignition on and

watch the information display for a

steering system warning message. If a

•

Loose or worn steering components.

Improper vehicle alignment.

Note: A high crown in the road or high

crosswinds may also make the steering

seem to wander or pull.

Adaptive Learning (If Equipped)

The electronic power steering system

adaptive learning helps correct road

irregularities and improves overall handling

and steering feel. It communicates with

the brake system to help operate

advanced stability control and accident

avoidance systems. Additionally, whenever

the battery is disconnected or a new

battery installed, you must drive your

vehicle a short distance before the system

relearns the strategy and reactivates all

systems.

WARNING: If the system detects

an error, you may not feel a difference in

the steering, however a serious condition

may exist. Have your vehicle checked as

soon as possible. Failure to do so may

result in loss of steering control.

Your vehicle has an electric power steering

system, there is no fluid reservoir, no

maintenance is required.

If your vehicle loses electrical power while

you are driving, electric power steering

assistance is lost. The steering system still

operates and you can steer your vehicle

manually. Manually steering your vehicle

requires more effort.

Extreme continuous steering may increase

the effort required for you to steer your

vehicle, this increased effort prevents

overheating and permanent damage to

the steering system. You do not lose the

ability to steer your vehicle manually.

Typical steering and driving maneuvers

allow the system to cool and return to

normal operation.

ice. Failure to take care may result in the

loss of control of your vehicle, serious

personal injury or death.

WARNING: Some situations and

objects prevent hazard detection. For

example low or direct sunlight, inclement

weather, unconventional vehicle types,

and pedestrians. Apply the brakes when

necessary. Failure to follow this

instruction could result in the loss of

control of your vehicle, personal injury or

death.

E255268

Alert: When active, a flashing visual

warning appears and an audible warning

tone sounds.

Brake Support: The system is designed

to help reduce the impact speed by

preparing the brakes for rapid braking.

Brake support does not automatically

apply the brakes. If you press the brake

pedal, the system could apply additional

braking up to maximum braking force, even

if you lightly press the brake pedal.

WARNING: The system cannot

help prevent all crashes. Do not rely on

this system to replace driver judgment

and the need to maintain a safe distance

and speed.

Active Braking: Active braking may

activate if the system determines that a

collision is imminent. The system may help

the driver reduce impact damage or avoid

the crash completely.

Using the Pre-Collision Assist

System

The system is active at speeds above

approximately 3 mph (5 km/h) and

pedestrian detection is active at speeds

up to 50 mph (80 km/h).

Driving Aids

Note: Brake Support and Active Braking are

active at speeds up to 75 mph (120 km/h).

If your vehicle has a radar sensor included

with Adaptive Cruise Control, then Brake

Support and Active Braking are active up to

the maximum speed of the vehicle.

Note: If you perceive Pre-Collision Assist

alerts as being too frequent or disturbing,

then you can reduce the alert sensitivity,

though the manufacturer recommends

using the highest sensitivity setting where

possible. Setting lower sensitivity would

lead to fewer and later system warnings.

Note: Pre-Collision Assist turns off when

you manually disable AdvanceTrac or when

you select deep snow/sand mode.

Distance Indication and Alert^(If

Equipped)

Distance Indication and Alert is a function

that provides the driver with a graphical

indication of the time gap to other

preceding vehicles traveling in the same

direction. Distance Indication and Alert

shows one of the graphics that follow in

the information display.

E254791

If the time gap to a preceding vehicle is

small, a red visual indication displays to

the driver.

Note: Distance Indication and Alert

deactivates and the graphics do not display

when Adaptive Cruise Control is active.

Blocked Sensors

You turn the steering wheel in an

attempt to steer around the vehicle.

After you turn the steering wheel, the

system applies additional steering torque

to help you steer around the vehicle. After

you pass the vehicle, the system applies

steering torque in the opposite direction to

encourage you to steer back into the lane.

The system deactivates after you fully pass

the vehicle.

steer around a vehicle. If you do not turn the

steering wheel, the system does not

activate.

If a message regarding a blocked sensor

or camera appears in the information

display, the radar signals or camera images

are obstructed. If your vehicle has a radar

sensor, it is behind the fascia cover in the

center of the lower grille. With a blocked

sensor or camera, the Pre-Collision Assist

system may not function, or performance

may reduce. The following table lists

possible causes and actions for when this

message displays.

Radar is out of alignment due to a front end

impact.

Note: Proper system operation requires a

clear view of the road by the camera. Have

any windshield damage in the area of the

camera's field of view repaired.

Note: If something hits the front end of your

vehicle or damage occurs and your vehicle

has a radar sensor, the radar sensing zone

may change. This could cause missed or

false detections. Contact an authorized
