DRIVER ALERT

 (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.

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:

If enabled in the menu, the system

activates at speeds above 40 mph
(64 km/h).

E249505

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 information
display.

Using Driver Alert

Switching the system on and off

You may switch the system on or off
through the information display.  See
General Information

 (page 109).  When

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

System Warnings

Note:

 The system does not issue warnings

below approximately 40 mph (64 km/h).

The warning system is in 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, another warning may be issued
which will remain in the information display
for a longer time. Press OK on the steering
wheel control to clear the warning. When
active the system will run automatically in
the background and only issue a warning
if required.

Resetting the System

You can reset the system by either:

•

Switching the ignition off and on.

•

Stopping your 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.

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.

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:

When Aid or both modes are selected

and the system detects no steering activity
for a short period, the system alerts 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.

E249505

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 does not affect the on or off
status of the system.  You can only change
the mode and intensity settings.

E173233

Press the button located on the
center console to switch the
system on or off.

known selection for each of these settings.
You do not need to readjust your settings
each time you turn on the system.

general zone coverage. They do not provide
exact zone parameters.

System Display

E144813

When you switch on the system,
an overhead graphic of a vehicle
with lane markings display in the

information display.

E173234

If you select aid mode when you
switch on the system, arrows
display with lane markings.

When you switch off the system, the lane

still be displayed if adaptive cruise control
is enabled.

While the system is on, the color of the
lane markings 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.

•

Your turn indicator is active.

•

Your vehicle is in a dynamic maneuver.

•

Quick braking.

•

Fast acceleration.

•

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,
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.
