Automatic standby mode
Pilot Assist is dependent on other systems, such
as Electronic Stability Control (ESC
66
). If any of
these other systems stops working, Pilot Assist
will automatically switch off.
WARNING With automatic standby mode, the driver is
warned by an acoustic signal and a message
on the instrument panel.
•
The driver must then regulate vehicle
speed, apply the brakes if necessary, and
maintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standby
mode if, e.g.:
• the driver opens the door.
• the brake temperature is high.
• the driver's hands are not on the steering
wheel.
• the parking brake is applied.
• the engine speed (rpm) is too low/high.
• the driver unbuckles the seat belt.
• one or more of the wheels lose traction.
• the camera/radar sensor is covered by snow
or heavy rain (the camera lens/radar waves
are blocked) •
your vehicle's speed goes below 5 km/h
(3 mph) and Pilot Assist cannot determine if
the vehicle ahead is stationary or if it is
another object, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Pilot Assist no longer has a vehicle to follow.
Reactivating Pilot Assist from standby
mode Note: This illustration is general and details may vary
depending on model.
To reactivate Pilot Assist:
–
Press the button on the steering wheel
(1).
>

Speed will be set to the most recently
stored speed.
WARNING A noticeable increase in speed may follow
when the speed is resumed with the
steering wheel button.

326 The previous illustration
69
shows that Pilot Assist
is set to maintain a speed of 110 km/h (68 mph)
and that there is no target vehicle ahead to fol-
low.
In this example, Pilot Assist will provide steering
assistance because it can detect the lane's side
marking lines.
Related information
• Pilot Assist (p. 311) Radar sensor
The radar sensor is used by several driver sup-
port systems to detect other vehicles. Note: This illustration is general and details may vary
depending on model.
The radar sensor is used by the following func-
tions:
• Distance Alert*
• Adaptive Cruise Control*
• Lane Keeping Aid
• Pilot Assist*
• City Safety
Any modifications to the radar sensor may make
its use illegal.
Related information
• Radar sensor limitations (p. 327)
• Recommended maintenance for the radar
sensor (p. 330)
• Radar sensor type approval (p. 330) 69
Note: This illustration is general and details may vary depending on mod\

Cause
Action
Water or snow is spraying/swirling up and blocking the radar signals or
the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-\
era/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radar
sensor. Consult a workshop to have the area of the windshield on the inside of t\
he cam-
era's casing cleaned. An authorized Volvo workshop is recommended.
NOTEKeep the windshield in front of the camera
and radar unit clean.
Vehicle speedThe radar sensor's ability to detect a vehicle
ahead is significantly reduced if:
• the speed of the vehicle ahead differs greatly
from your vehicle's speed
Limited field of visionThe radar sensor has a limited field of vision. In
some situations, it may detect a vehicle later than
expected or not at all. The radar sensor's field of vision.
The radar sensor's detection of vehicles very
close to your vehicle may be delayed in cer-
tain situations, e.g. if a vehicle pulls inbetween your vehicle and the vehicle directly
ahead. Small vehicles, such as motorcycles, or vehi-
cles that are not driving in the center of the
lane may remain undetected.
In curves, the radar may detect the wrong
vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi-
ble for the radar to detect. The driver should be
extra alert when driving behind vehicles towing
low trailers when Adaptive Cruise Control or Pilot
Assist is activated.

DRIVER SUPPORT
* Option/accessory.331
Camera
The camera is used by several driver support
systems to e.g. detect lane marker lines or road
signs. Note: This illustration is general and details may vary
depending on model.
The camera is used by the following functions:
• Adaptive Cruise Control*
• Pilot Assist*
• Lane Keeping Aid*
• Steering assistance at risk of collision
• City Safety
• Driver Alert Control*
• Road Sign Information*
• Active high beams*

radar sensor (p. 335)
