DRIVER ALERT

 (If Equipped)

PRINCIPLE OF OPERATION

WARNINGS

The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are

still responsible to drive with due care and
attention.

At all times, you are responsible for
controlling your vehicle, supervising
the system and intervening, if

required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death.

The system may not function if the
sensor is blocked.

Take regular rest breaks if you feel
tired. Do not wait for the system to
warn you.

Certain driving styles may result in
the system warning you even if you
are not feeling tired.

In cold and severe weather
conditions the system may not
function. Rain, snow and spray can

all limit sensor performance.

The system will not operate if the
sensor cannot track the road lane
markings.

If damage occurs in the immediate
area surrounding the sensor, have
your vehicle checked as soon as

possible.

The system may not correctly
operate if your vehicle is fitted with
a suspension kit not approved by us.

Note: Keep the windshield free from
obstructions. For example, bird droppings,
insects and snow or ice.

Note: If the camera is blocked or if the
windshield is damaged, the system may not
function.

Note: The system will store the on or off
setting in the information display menu
through ignition cycles.

Note: If enabled in the menu, the system
activates at speeds above 40 mph
(64 km/h). When below the activation
speed, the information display informs the
driver that the system is unavailable.

The system automatically monitors your
driving behavior using various inputs
including the front camera sensor.

If the system detects that your driving
alertness is reduced below a certain
threshold, the system will alert you using
a chime and a message in the cluster
display.

USING DRIVER ALERT

Switching the System On and Off

Switch the system on or off using the
information display.  See General
Information (page 104).

When activated, the system will monitor
your alertness level based upon your
driving behavior in relation to the lane
markings, and other factors.

System Warnings

Note: The system will not issue warnings
below approximately 40 mph (64 km/h).

The warning system has two stages. At
first, the system issues a temporary
warning that you need to take a rest. This
message will only appear for a short time.
If the system detects further reduction in
driving alertness, it may issue another
warning that will remain in the information
display for a longer time. You can press OK
on the steering wheel control to clear the
warning.

Resetting the System

You can reset the system by either:

•

Switching the ignition off and on.

•

Stopping the vehicle and then opening
and closing the driver’s door.

LANE KEEPING SYSTEM

 (If

Equipped)

WARNINGS

The system is designed to aid the
driver. It is not intended to replace
your attention and judgment. You are

still responsible to drive with due care and
attention.

Always drive with due care and
attention when using and operating
the controls and features on your

vehicle.

At all times, you are responsible for
controlling your vehicle, supervising
the system and intervening, if

required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death.

In cold and severe weather
conditions the system may not
function. Rain, snow and spray can

all limit sensor performance.

WARNINGS

The system will not operate if the
sensor cannot track the road lane
markings.

The sensor may incorrectly track lane
markings as other structures or
objects. This can result in a false or

missed warning.

Large contrasts in outside lighting
can limit sensor performance.

The system may not operate
properly if the sensor is blocked.
Keep the windshield free from

obstruction.

If damage occurs in the immediate
area surrounding the sensor, have
your vehicle checked as soon as

possible.

The sensor is located near the rear view
mirror.

Note: The system works above 40 mph
(64 km/h).

Note: The system works as long as the
camera can detect one lane marking.

Note: The system may not function if the
camera is blocked or there is damage to the
windshield.

Note: When Aid mode is on and the system
detects no steering activity for a short
period, the system will alert you to put your
hands on the steering wheel. The system
may detect a light grip or touch on the
steering wheel as hands off driving.

The system notifies you to stay in your lane
through the steering system and the
instrument cluster display when the front
camera detects an unintentional drift out
of your lane is likely to occur. The system
automatically detects and tracks the road
lane markings using a camera mounted
behind the interior rear view mirror.

Switching the System On and Off

Note: The system on or off setting is stored
until it is manually changed, unless a MyKey
is detected. If the system detects a MyKey
it defaults to on and the mode is set to Alert.

Note: If a MyKey is detected, pressing the
button will not affect the on or off status of
the system.

Press the button on the steering
wheel stalk to switch the system
on or off.

System Settings

The system has optional setting menus
available. The system stores the
last-known selection for each of these
settings. You do not need to readjust your
settings each time you turn on the system.

Mode: This setting allows you to select
which of the system features you can
enable.

Alert only – Provides a steering wheel
vibration when the system detects an
unintended lane departure.

Aid only – Provides an assistance steering
torque input toward the lane center when
the system detects an unintended lane
departure.

Alert

A

Aid

B

Alert + Aid – Provides an assistance
steering torque input toward the lane
center. If your vehicle continues drifting out
of the lane, the system provides a steering
wheel vibration.

Note: The alert and aid diagrams illustrate
general zone coverage. They do not provide
exact zone parameters.

Intensity: This setting affects the intensity
of the steering wheel vibration used for the
alert and alert + aid modes. This setting
does not affect the aid mode.

System Display

When you switch on the system, an
overhead graphic of a vehicle with lane
markings will display in the information
display. If you select aid mode when you
switch on the system, a separate white
icon will also appear or in some vehicles
arrows will display with the lane markings.

When you switch off the system, the lane
marking graphics will not display.

While the system is on, the color of the
lane markings will change to indicate the
system status.

Gray: Indicates that the system is
temporarily unable to provide a warning
or intervention on the indicated side(s).
This may be because:

•

Your vehicle is under the activation
speed.

•

The turn indicator is active.

•

Your vehicle is in a dynamic maneuver.

•

The road has no or poor lane markings
in the camera field-of-view.

•

The camera is obscured or unable to
detect the lane markings due to
environmental conditions (significant
sun angles, shadows, snow, heavy rain
or fog), traffic conditions (following a
large vehicle that is blocking or
shadowing the lane), or vehicle
conditions (poor headlamp
illumination).

See Troubleshooting for additional
information.

Green: Indicates that the system is
available or ready to provide a warning or
intervention, on the indicated side(s).

Yellow: Indicates that the system is
providing or has just provided a lane
keeping aid intervention.

Red: Indicates that the system is providing
or has just provided a lane keeping alert
warning.

The system can be temporarily suppressed
at any time by the following:

•

Quick braking.

•

Fast acceleration.

•

Using the turn signal indicator.

•

Evasive steering maneuver.

Troubleshooting

Why is the feature not available (line markings are gray) when I can see the lane markings

on the road?

Vehicle speed is outside the operational range of the feature

Sun is shining directly into the camera lens

Quick intentional lane change
