Changing Automatic Speed Limiter

tolerance

The Automatic Speed Limiter (ASL) can be set
to different tolerance levels.

It is also possible to allow the vehicle to drive
above or below the posted speed limit. For exam-
ple, if the vehicle is following a current posted
speed limit of 70 km/h (43 mph), the driver can
instead allow the vehicle to maintain a speed of
75 km/h (47 mph).

Function buttons and symbols

–

Tap the

(1) button on the steering

wheel keypad until 70 km/h (43 mph) has
been changed to 75 km/h (47 mph) in the
center of the speedometer (4).
> The vehicle will then use the selected tol-

erance of 5 km/h (4 mph) as long as the
posted speed limit the vehicle passes is
70 km/h (43 mph).

This tolerance level will be followed until
the vehicle passes a sign with a lower or
higher speed. The vehicle will then adjust
to the new speed limit and the set toler-
ance will be deleted from the system's
memory.

If Road Sign Information*

is activated,

the posted speed limit will also be indi-
cated by a RED marking on the speedom-
eter.

The set tolerance can be adjusted in the same
way as for the Speed Limiter's speed.

NOTE

The highest possible selectable tolerance is
+/- 10 km/h (5 mph).

Automatic Speed Limiter limitations

Automatic Speed Limiter (ASL) utilizes the
speed limit information provided by the RSI

function, not from the speed limit signs that the
vehicle passes.

If RSI

is unable to interpret and provide ASL

with speed information, ASL will go into standby
mode and switch over to SL. The driver will then
have to actively brake to bring the vehicle down
to the appropriate speed.

ASL will be reactivated when RSI

is once again

able to interpret and provide speed information to
ASL.

See “Road Sign Information limitations” for more
information.

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.

Using engine braking instead of
applying the brakes

Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver can temporarily disengage the Cruise Con-
trol braking function.

To disengage CC:

–

Press the accelerator pedal about halfway
down and then release it.
> Cruise Control will automatically disen-

gage the automatic brake function and
speed will only be reduced using the
engine braking function.

How drive mode affects cruise control

The way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode

Cruise Control Eco Cruise with ECO drive
mode

In the ECO drive mode, cruise control's accelera-
tion and deceleration will be smoother than in
other drive modes to help provide optimal fuel
efficiency and reduced environmental impact.
Because of this, the vehicle's actual speed may
be slightly above or below the set speed.

For more information, see "ECO drive mode"
under "Eco Cruise".

Cruise Control Dynamic Cruise

With the Dynamic drive mode, cruise control's
acceleration and deceleration will be faster and
more immediate than in other drive modes.

Distance Alert*

The Distance Alert

function can help the driver

become aware if the time interval to the vehicle
in front is too short.

However, the vehicle must be equipped with a
head-up display in order to display the Distance
Alert, which will then be indicated by a symbol
on the windshield as long as the time interval to
the vehicle ahead is shorter than the set time
interval.

Distance Alert is active at speeds above 30 km/h
(20 mph) and only reacts for vehicles ahead mov-
ing in the same direction as your vehicle. No dis-
tance information is provided for oncoming, slow-
moving or stationary vehicles.

Distance Alert warning light on the windshield

A warning light will appear on the windshield and
glow steadily if the time interval to the vehicle
ahead is shorter than the set time interval.

NOTE

Distance Alert limitations

Distance Alert functionality may be reduced in
certain situations.

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".

Adaptive Cruise Control*

Adaptive Cruise Control (ACC

) 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

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.

•

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).

304

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.
