Radar blocked
See manualCollision Warning and Auto-brake are temporarily not functioning. The radar sensor is blocked, for
example by heavy rain or snow that has accumulated in front of the sensor, and cannot detect other
vehicles, see page 168 for more information on the radar sensor’s limitations.

Adaptive Cruise Control (ACC)*
04
168* Option/accessory, for more information, see Introduction.
WARNING
•Only use a time interval that is suitable
in current traffic conditions.
•A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is acti-
vated, see page 172 .
Deactivating and resuming settingsCruise control is deactivated, either with a
short press on
, or by action taken by the
driver, such as braking, etc. The set speed, for
example 55 mph, is then shown in parenthe-
ses. Speed and time interval are resumed by
pressing
.
WARNING
There may be a significant increase in speed
after the button has been pressed.
A short press on in standby mode or a long
press in active mode deactivates cruise con-trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time
is pressed.
Deactivation due to action by the driverACC is deactivated:
•when the brakes are applied
•if the gear selector is moved to N
•if the accelerator pedal is depressed for an
extended period.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cruise Control
Canceled is shown in the display. The drivermust then intervene and adapt the vehicle's
speed to the surrounding traffic.
Automatic deactivation may be caused if:
•the vehicle's speed falls below 20 mph
(30 km/h)
•the wheels lose traction or if the anti-lock
brake system (ABS) is activated
•brake temperature is high
•engine speed (rpm) is too low
•the radar sensor is obstructed by, for
example, wet snow or rain.
The radar sensor and its limitations
The radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor's capacity to detect vehicles
ahead is impeded:

* Option/accessory, for more information, see Introduction.169
•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.
•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.
G021414
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.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.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.
