Activating/deactivating Automatic
Speed Limiter
The Automatic Speed Limiter (ASL) is a supple-
ment to the Speed Limiter (SL) and can be acti-
vated/deactivated.
Activating ASLThe Speed Sign Assist but- ton is located in the center dis-
play's Function view. To activate the Automatic Speed Limiter:
1.
Tap the Speed Sign Assist button.
>

ASL will go into standby mode and a
green indicator light will illuminate. A road
sign symbol will be displayed in the center
of the speedometer in the instrument
panel.
2. Pressing the button on the steering
wheel keypad.
>

ASL will be activated and set to the vehi-
cle's current speed.
NOTE
If the Automatic Speed Limiter function is
activated, road sign information is shown
in the driver display even if RSI 19
is not
activated.
To remove road sign information from the
driver display, you must deactivate both
Automatic Speed Limiter and RSI.
When the Automatic Speed Limiter func-
tion is activated but RSI is deactivated, no
warnings are given from RSI. RSI must
also be activated for warnings to be pos-
sible.
Deactivating ASLTo deactivate the Automatic Speed Limiter:
–
Tap the
Speed Sign Assist button in Func-
tion view.
>
ASL will be deactivated, the indicator light
in the button will be GRAY and SL will be
activated instead.
WARNING The vehicle will no longer follow the posted
maximum speed after switching from ASL to
SL – it then only follows the maximum speed
stored in the memory.

WARNING

The cruise control function is supplemen-
tary driver support intended to facilitate
driving and help make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
Cruise control is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Standby mode due to action by the driver
Cruise Control will be temporarily deactivated and
put in standby mode if: the brakes are applied
the gear selector is moved to N
the vehicle is driven faster than the set
speed for more than 1 minute
The driver must then control the vehicle's speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Automatic standby mode
Cruise Control will be temporarily deactivated and
put in standby mode if:
the wheels lose traction
the engine speed (rpm) is too low/high
the temperature in the brake system
becomes too high
the vehicle's speed goes below 30 km/h
(20 mph).
The driver must then control the vehicle's 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
other vehicles at all.
The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.
The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.
Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.
Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see. Poor
weather or winding roads can affect the
radar sensor's capacity to detect vehicles
ahead.
A vehicle's size (e.g., a motorcycle) can
also affect the radar sensor's capacity to
detect another vehicle. This may result in
the warning light illuminating at a shorter
distance than the one that has been set
or not illuminating at all.
High speeds may also result in the warn-
ing light illuminating at a shorter distance
than the one that has been set due to
limitations in the radar sensor's range.
NOTE The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

Distance Alert* (p. 296)
Radar sensor limitations (p. 333) Adaptive Cruise Control*
Adaptive Cruise Control (ACC 38
) helps the
driver maintain a constant speed with a set time
interval to the vehicle ahead.
Adaptive Cruise Control helps provide a more
relaxed driving experience on long trips on high-
ways or long, straight roads with even traffic
flows. The camera/radar sensor measures the distance to the
vehicle ahead
39
.
The driver sets a speed and a time interval to the
vehicle ahead. If the camera/radar sensor detects
a slower-moving vehicle ahead, your vehicle's
speed will be automatically adapted according to
the set time interval to that vehicle. When there
are no longer slower-moving vehicles ahead, the
vehicle will return to the set speed.

WARNING
The Adaptive Cruise Control function is
supplementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
Adaptive Cruise Control is not a substi-
tute for the driver's attention and judg-
ment. The driver is always responsible for
ensuring the vehicle is driven in a safe
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.
NOTE Depending on market, this function may be
either Standard or Optional.
Adaptive Cruise Control regulates speed by
accelerating and braking. It is normal for the brakes to emit a slight sound when they are
being used to adjust speed.
Adaptive Cruise Control always attempts to regu-
late speed smoothly. The driver must apply the
brakes in situations requiring immediate braking.
For example, when there are great differences in
speed between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the radar
sensor, braking may occur unexpectedly or not at
all.
Adaptive Cruise Control is designed to follow a
vehicle ahead in the same lane and maintain a
time interval to that vehicle set by the driver. If the
radar sensor does not detect a vehicle ahead, it
will instead maintain the speed set by the driver.
This will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehicle.
Adaptive Cruise Control can follow another
vehicle at speeds from a standstill up to
200 km/h (125 mph).
WARNING
Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible and must intervene if the sys-
tem fails to detect a vehicle ahead.
Adaptive Cruise Control does not brake
for people or animals and does not brake
for small vehicles, such as bikes and
motorcycles. Similarly, it does not brake
for low trailers, oncoming, slow-moving or
stationary vehicles and objects.
Do not use Adaptive Cruise Control in
demanding situations, such as in city traf-
fic, at intersections, on slippery surfaces,
with a lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.
CAUTION Maintenance of Adaptive Cruise Control com-
ponents may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.
