DRIVER ALERT

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: The system assists you when driving
on fast main roads and freeways.

Note: The system calculates an alertness
level at vehicle speeds above approximately
40 mph (65 km/h).

The system automatically monitors your
driving behavior.

The system is designed to alert you if it
detects that you are becoming drowsy or
if your driving deteriorates.

Using Driver Alert

Switching the System On and Off

Switch the system on using the information
display. See Information Displays (page
91).

Note: The system remains on or off
depending on how it was last set.

The system calculates your alertness level
based upon your driving behavior in relation
to the lane markings and other factors.

System Warnings

Note: The system does not warn you if the
vehicle speed falls below approximately
40 mph (65 km/h).

The warning system has two stages:
1.

A temporary warning is issued to advise
you to take a rest. This message only
appears for a short time.

2. If you do not rest and the system

continues to detect that your driving

This remains in the information display
until you cancel it. See Information
Messages (page 95).

Press OK on the steering wheel control to
remove the warning.

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.

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.

WARNINGS

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: 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.
