if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE Keep the area in front of the radar sensor
clean.
\b
if the speed of vehicles ahead is signifi-
cantly different from your own speed.
WARNING The radar sensor has a limited field of vision.
In some situations it may detect a vehicle
later than expected or not detect vehicles at
all.
Radar sensor field of vision (gray)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters thelanes between your vehicle and the one
that the system has already detected. Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
In curves, the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
Fault tracing and actions
If the message Radar blocked See manual is
displayed, this means that the radar signals
from the sensor have been obstructed and that
a vehicle ahead cannot be detected.
This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning
System with Auto-brake will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions. Cause Action
The surface of the radar in the grille is dirty or obstructed in some wa\
y. Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals. No action possible. Heavy precipitation may affect the function of the
radar. G02141

* Option/accessory, for more information, see Introduction. 177Cause Action
Swirling water or snow from the surface of the road may interfere with
the radar signals. No action possible. A very wet or snow-covered road surface may affect
the function of the radar.
The surface of the radar is clean but the message remains in the display\
. Wait a short time. It may take several minutes for the radar to detect t\
hat
it is no longer obstructed.

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.
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.
– 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. No. of bars Approx. time interval
(in seconds) 1 1.0
2 1.4
3 1.8
4 2.2
5 2.6
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward. G031394 G031396

to the right in the display. The same symbol is
also displayed when Adaptive Cruise Control is
activated.
NOTE
\b
The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
\b The set time interval is also used by
Adaptive Cruise Control, see page
174.
WARNINGOnly 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
175 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 \b
Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
\b 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. Symbol Message Description
- Time interval while it is being set.
- Time interval after it has been set.

settings Driver Alert and 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
\b
An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
\b In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest. G01732

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
LDW can be switched on or off by pressing the
button on the center console. A light in the but-
ton illuminates when the function is on.
The trip computer display shows Lane Depart
Warn Unavailable when the function is in
standby mode.
When LDW is in standby mode, the function is
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:
\b The turn signal is being used
\b The driver’s foot is on the brake pedal 1
\b The throttle pedal is pressed quickly
\b If the steering wheel is moved quickly
\b In sharp turns that cause the vehicle’s
body to sway.
See page 162 for information on the camera’s
limitations.
WARNING The driver will only be warned once for each
time the wheels cross a marker line. No
alarm will be given if a marker line is
between the wheels.
