WHAT IS DRIVER ALERT
Driver alert alerts you if it determines that
you are becoming drowsy or if your driving
deteriorates.
HOW DOES DRIVER ALERT
WORK
Driver Alert calculates your alertness level
based on your driving behavior in relation
to the lane markings and other factors
through use of the front camera sensor
behind the interior mirror.

may result in the system warning you
even if you are not feeling tired. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
The system will not
operate if the sensor cannot track the
road lane markings. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. WARNING:
The system may not
correctly operate if your vehicle is fitted
with a suspension kit not approved by
us. WARNING:

behind the interior mirror to detect speed
signs.
If your vehicle has speed sign recognition
with navigation, stored speed sign data
may influence the indicated speed limit
value.

WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and

automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle.
Note: The system is not a substitute for
safe driving practices. Always be aware of
your vehicle and trailer combination, and
the surrounding environment.

prevent your vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: The front end of your vehicle swings
out when changing the direction of the
trailer.
Note: In certain conditions, the trailer could
turn faster or the trailer angle could increase
more than anticipated. Always monitor the
clearance between the trailer and vehicle
and the surroundings.
