Cruise control standby mode

Automatic standby mode

Adaptive Cruise Control may go into standby

mode if:

Cruise control (CC¹⁸) can be deactivated and

put in standby mode. This may happen auto-

matically or be due to driver intervention.

Standby mode means that the function is

selected in the instrument panel but not acti-

vated. In standby mode, cruise control will not

regulate speed.

Adaptive Cruise Control (ACC²⁰) helps the

driver maintain a constant speed with a set

time interval to the vehicle ahead.

Temporarily increasing speed using the accel-

erator pedal, e.g. when passing another vehi-

cle, will not affect the setting. The vehicle will

return to the set speed when the accelerator

pedal is released.

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 vehi-

cle. When there are no longer slower-moving

vehicles ahead, the vehicle will return to the

set speed.

Adaptive Cruise Control always attempts to

regulate speed smoothly. The driver must

apply the brakes in situations requiring imme-

diate 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.

WARNING

Setting time interval to the vehicle ahead

(p. 308)

The function is supplementary driver

support intended to facilitate driving

and help make it safer – it cannot han-

dle all situations in all traffic, weather

and road conditions.

•

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.

Auto-hold braking with driver support

(p. 309)

The driver is advised to read all sec-

tions in the Owner's Manual about this

function to learn of its limitations,

which the driver must be aware of

before using the function.

port (p. 306)

CAUTION

Driver support functions are not a sub-

stitute for the driver's attention and

judgment. The driver is always respon-

sible 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.

Only a workshop may perform mainte-

nance on driver support components – an

authorized Volvo workshop is recom-

mended.

WARNING

limitations

This is not a collision avoidance sys-

tem. The driver is always responsible

and must intervene if the system fails

to detect a vehicle ahead.

•

Adaptive Cruise Control (ACC³¹) may have

limited functionality in certain situations.

Steep roads and/or heavy loads

The function does not brake for people

or animals and does not brake for small

vehicles, such as bikes and motorcy-

cles. Similarly, it does not brake for low

trailers, oncoming, slow-moving or sta-

tionary vehicles and objects.

Adaptive Cruise Control is primarily intended

to be driven on flat roads. The function may

not be able to maintain the correct time inter-

val to the vehicle ahead when driving down

steep hills. The driver should be extra attentive

and prepared to apply the brakes.

Do not use the function in demanding

situations, such as in city traffic, 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.

•

Do not use Adaptive Cruise Control if the vehi-

cle is carrying a heavy load or towing a trailer.

Other limitations

The Off Road drive mode cannot be selected

if Adaptive Cruise Control is activated.

NOTE

The function uses the vehicle's camera and

radar sensor, which has certain general

limitations.
