WARNING
The Electronic Stability Control system
ESC is supplementary driver support
intended to facilitate driving and make it
safer – it cannot handle all situations in
all traffic, weather and road conditions.
ESC is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle 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.
Stability control 3This function helps control the driving and brak-
ing force of each individual wheel in an attempt
to stabilize the vehicle.
Spin control and active yaw controlThis function is active at low speeds and brakes
the wheels that are spinning to transfer additional
power from wheels that are not spinning.
This function also helps prevent the wheels from
spinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC
4
) helps prevent inad-
vertent wheel lock, e.g. after downshifting or
using engine braking when driving at low speeds
on a slippery surface.
Inadvertent wheel lock while driving could impair
the driver's ability to steer the vehicle.
Trailer Stability Assist* 5
Trailer Stability Assist (TSA
6
) is designed to help
stabilize a vehicle that is towing a trailer if the
vehicle and trailer have begun to sway. For more
information, see "Trailer Stability Assist".
NOTE The TSA function is deactivated if
ESC Sport
Mode is activated.

Adaptive Cruise Control* (p. 300) Passing assistance with Adaptive
Cruise Control
Adaptive Cruise Control (ACC
48
) can assist the
driver when passing other vehicles.
How passing assistance worksWhen ACC is following another vehicle and you
indicate that you intend to pass that vehicle by
using the turn signal 49
, Adaptive Cruise Control
will begin accelerating toward the vehicle ahead
before your vehicle has moved into the passing
lane.
The function will then delay a speed reduction to
avoid early braking as your vehicle approaches a
slower-moving vehicle.
The function remains active until your vehicle has
passed the other vehicle.
WARNING Please note that this function can be acti-
vated in more situations than just passing
another vehicle, such as when a direction indi-
cator is used to indicate a lane change or
before exiting to another road – the vehicle
will then briefly accelerate.

Adaptive Cruise Control (ACC 53
) may have lim-
ited functionality in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended to
be driven on flat roads. The function may not be
able to maintain the correct time interval to the
vehicle ahead when driving down steep hills. The
driver should be extra attentive and prepared to
apply the brakes.
Do not use Adaptive Cruise Control if the
vehicle is carrying a heavy load or towing a
trailer.
Other limitations

The
Off Road drive mode cannot be
selected if Adaptive Cruise Control is acti-
vated.
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

When the vehicle is approaching an off-ramp
or a fork in the road, the driver should steer
toward the desired lane to indicate to Pilot
Assist the desired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, it
strives to position the vehicle in the center of the
lane between the lane markings. For the smooth-
est driving experience possible, the driver should
permit the vehicle to find the optimal positioning.
The driver should check that the vehicle is posi-
tioned safely in the lane and can always adjust
the vehicle's position by applying more force to
the steering wheel.
If Pilot Assist does not position the vehicle
appropriately in the lane, the driver should
turn off Pilot Assist or switch to Adaptive
Cruise Control.

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.
