Electronic stability control (ESC) -  
general  
Stability system ESC (Electronic Stability  
Control) helps the driver to avoid skidding and  
improves the car's traction.  
Adjustable steering force*  
MY CAR (p. 113)  
Speed related power steering causes the steer-  
ing wheel force to increase with the speed of the  
car in order to give the driver enhanced sensitiv-  
ity.  
On motorways the steering feels firmer. Steering  
is light and requires no extra effort when parking  
and at low speed.  
The activation of the ESC system dur-  
ing braking may be noticed as a throb-  
bing sound. The car may accelerate  
slower than expected when the accel-  
erator pedal is depressed.  
The driver can choose between three different  
levels of steering force for road responsiveness  
or steering sensitivity in the menu system MY  
CAR (p. 113):  
WARNING  
The stability system ESC is supplemen-  
tary driver support intended to facilitate  
driving and make it safer – it cannot han-  
dle all situations in all traffic, weather and  
road conditions.

Once there, search for Steering force level  
and select Low, Medium or High.

This menu is not accessible when the car is mov-  
ing.  
ESC is not a substitute for the driver's  
attention and judgement. The driver is  
always responsible for ensuring the car is  
driven in a safe manner, at the appropri-  
ate speed, with an appropriate distance to  
other vehicles, and in accordance with  
current traffic rules and regulations.  
NOTE  
In certain situations the power steering may  
become too hot and then needs to be tempo-  
rarily cooled - during this time the power  
steering operates with reduced power and  
turning the steering wheel may then be per-  
ceived to be slightly heavier.  
The ESC system consists of the following func-  
tions:  
In parallel with the temporarily reduced steer-  
ing assistance the combined instrument panel  
shows a message.  
Active Yaw Control

CTC (Corner Traction Control) compensates for  
understeer and allows higher than normal accel-  
eration in a bend without wheelspin on the inner  
wheel, e.g. on an arcing motorway entrance road  
to quickly reach the prevailing traffic speed.

Active Yaw Control  
The function checks the driving and brake force  
of the wheels individually in order to stabilise the  
car.  
Driver Steering Recommendation –  
DSR  
DSR (Driver Steering Recommendation) helps  
the driver steer the car in the right direction when  
there is reduced traction or when the ABS sys-  
tem engages.  
Spin Control  
The function reduces engine power if the drive  
wheels slip against the underlying surface in  
order to maintain stability and traction.  
The primary role of the DSR function is to help  
the driver steer in the right direction when the car  
is skidding.  
Traction control system  
The function is active at low speed and transfers  
power from the driving wheel that is spinning to  
the one that is not.  
DSR engages by applying slight torque to the  
steering wheel in the direction in which the car  
should be steered to maintain/achieve maximum  
possible traction and stabilise the car.  
Engine drag control - EDC  
EDC (Engine Drag Control) prevents involuntary  
wheel locking, e.g. after shifting down or engine  
braking when driving in low gears on slippery  
road surfaces.  
Trailer Stability Assist* - TSA1  
Trailer stability assist (p. 314) function is to sta-  
bilise the car and trailer combination if it begins  
to snake. For more information, see Driving with a  
trailer (p. 307).  
Involuntary wheel locking while driving can,  
amongst other things, impair the driver's ability to  
steer the car.  
NOTE  
The function is deactivated if the driver  
selects Sport mode.

Trailer Stability Assist is included in the installation of the Volvo genuine towbar.
