Distance alert

172
Introduction
Distance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Time interval information is only given for a
vehicle that is driving ahead of your vehicle, in
the same lane, and in the same direction. No
information is provided for vehicles driving
toward you, moving very slowly, or at a stand-
still.
G017362
A smaller section of the red warning light in the
windshield glows steadily if your vehicle is
closer to the vehicle ahead than the set time
interval.
NOTE
Distance Alert is in active mode while Adap-
tive Cruise Control is active.
Distance Alert is active at speeds above
approximately 20 mph (30 km/h).
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.
Operation

Press the button in the center instrument
panel to switch this function on or off.
> The indicator light in the button illumi-
nates when the function is on.
Setting a time intervalThe buttons for setting a time interval are
located on the left side of the steering wheel,
see the illustration on page 167 .

Press
to increase the interval or to
decrease it.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval.

also displayed when Adaptive Cruise Control is
activated.
NOTE
•The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
•The set time interval is also used by
Adaptive Cruise Control, see page 167.
WARNING
Only use a time interval that is suitable in
current traffic conditions.
LimitationsThe Distance Alert function uses the same
radar sensor used by Adaptive Cruise Control
and the Collision Warning system. See page
168 for more information on the radar sensor’s
limitations.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
WARNING
•Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
•The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.

Driver Alert System*
04

* Option/accessory, for more information, see Introduction.175 Introduction
The Driver Alert System is designed to help a
driver who may be becoming fatigued or who
is inadvertently leaving the lane.
The Driver Alert System consists of two differ-
ent functions that can be switched on together
or separately.
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW)
When one or both of the functions has been
switched on, it is in standby mode and is acti-
vated when the vehicle exceeds a speed of
40 mph (65 km/h).
The function deactivates if speed goes under
37 mph (60 km/h).
Both functions use a camera that is dependent
on the road/lane being clearly marked by pain-
ted lines on each side.
WARNING
The Driver Alert system does not function in
all situations and is designed to be a sup-
plementary aid. It is not, however, intended
to replace the driver’s attention and judge-
ment.
Driver Alert Control (DAC)–general
information
G017332
This function is intended to alert the driver if
his/her driving becomes erratic, such as if the
driver is distracted or fatigued.
NOTE
The camera has certain limitations, see
page 161.
A camera monitors the painted lines marking
the lane in which the vehicle is traveling and
compares the direction of the road with the
driver’s movements of the steering wheel. The
driver is alerted if the vehicle does not follow
the lane smoothly.DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
WARNING
•DAC is not intended to extend the dura-
tion of driving. Always plan breaks at
regular intervals to help remain alert.
•In certain cases, fatigue may not affect
the driver’s behavior. In situations of
this type, no warning will be provided.
Therefore, it is important to take breaks
at regular intervals, regardless of
whether or not DAC has given a warn-
ing.
LimitationsIn certain situations, DAC may provide warn-
ings even if the driver’s driving pattern has not
become erratic.
•if the driver is testing the LDW function
•in strong crosswinds
•on grooved road surfaces.

Operating DAC
Certain settings can be made from the menu
system controlled from the center instrument
panel, see page 120 for more information on
the menu system.
The current system status can be checked on
the trip computer’s display by using the but-
tons on the left steering wheel lever.
Thumb wheel. Turn this wheel until Driver
Alert is displayed. The second line shows
the alternative Off, Unavailable, or[-----], i.e., the number of bars.
READbutton. Confirms and erases a mes-
sage in the display.
Activating DACIn the center instrument panel, go to Car
settings Driver Alertand select On.
The function is activated when the
vehicle exceeds a speed of 40 mph
(65 km/h). The display will show level
markings of 1–5 bars, where a low
number of bars indicates erratic driving. A high
number of bars indicates stable driving.
If the vehicle is being driven erratically, the
driver will be alerted by an audible signal and
the message Driver Alert, Time for a break is
displayed. The warning will be repeated after a
short time if the driving pattern remains the
same.
WARNING
•An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
•In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest.

Lane Departure Warning (LDW)–
general information
This function is designed to help reduce the
risk of accidents in situations where the vehicle
leaves its lane and there is a risk of driving off
the road or into the opposite lane. LDW con-
sists of a camera that monitors the lane’s side
marker lines. The driver is alerted by an audible
signal if the vehicle crosses a side marker line
or the road’s center dividing line.
Operation and function

button on the center console. A light in the but-
ton illuminates when the function is on.
The trip computer display shows

activated automatically after the camera has
monitored the road’s side marker lines and the
vehicle’s speed exceeds 40 mph (65 km/h).
Lane Depart Warn Available will be dis-
played.If the camera can no longer monitor the road’s
side marker lines, or if the vehicle’s speed falls
below 37 mph (60 km/h), LDW will return to
standby mode and
Lane Depart Warn
Unavailable will be displayed.
If the vehicle unexpectedly crosses the lane’s
left or right side marker lines, the driver will be
alerted by an audible signal.
No warning signal will be given in the follow-
ing situations:
•The turn signal is being used
•The driver’s foot is on the brake pedal1
•The throttle pedal is pressed quickly
•If the steering wheel is moved quickly
•In sharp turns that cause the vehicle’s
body to sway.
See page 161 for information on the camera’s
limitations.

time the wheels cross a marker line. No
alarm will be given if a marker line is
between the wheels.
1A warning will be given even when Increased sensitivity has been selected.

180* Option/accessory, for more information, see Introduction.
Introduction
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
This system is available in the rear bumper
only, or in both the front and rear bumpers.
Park assist utilizes four ultrasound sensors in
the bumper(s) to measure the distance to a
vehicle, object, or a person who may be close
to the front or rear of your vehicle. An audible
signal and symbols in the audio system’s dis-
play indicate the distance to the object

Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
