157 Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of the stability system's permanent
functions and cannot be switched off.

Thumb wheel
RESET button
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (A) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (B) to toggle
between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily been switched off.
•The spin control function is automati-
cally enabled each time the engine is
started.
•DSTC ON indicates that all system
functions are active.
Active yaw control – AYC (DSTC only)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of the stability system's permanent
functions and cannot be switched off.

189 Snow chains
Snow chains can be used on your Volvo with
the following restrictions:
•Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
•Certain size tires may not allow the assem-
bly of snow chains/traction devices.
Consult your Volvo retailer for additional snow
chain information.
CAUTION
•Check local regulations regarding the
use of snow chains before installing.
•Always follow the chain manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.
•Never exceed the chain manufacturer's
specified maximum speed limit. (Under
no circumstances should you exceed
31 mph (50 km/h).
•Avoid bumps, holes or sharp turns
when driving with snow chains.
•The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires
Tires for winter use:
•Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are strongly
advised to fit suitable winter tires to help
retain the highest degree of traction.
•It is important to install winter tires on all
four wheels to help retain traction during
cornering, braking, and accelerating. Fail-ure to do so could reduce traction to an
unsafe level or adversely affect handling.
•Do not mix tires of different design as this
could also negatively affect overall tire road
grip.
•Winter tires wear more quickly on dry roads
in warm weather. They should be removed
when the winter driving season has ended.
•Studded tires should be run-in
300–600 miles (500–1000 km) during
which the car should be driven as smoothly
as possible to give the studs the opportu-
nity to seat properly in the tires. The tires
should have the same rotational direction
throughout their entire lifetime.
NOTE
Please consult state or provincial regula-
tions restricting the use of studded winter
tires before installing such tires.
