accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps
improve tractive force.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force. This is
done by pressing the STC/DSTC button on the center control panel for at \
least a half a second.
When the SC function has been switched off:
l The text window will briefly display "SPIN CONTROL OFF"
l The LED in the STC/DSTC button will be off.
The following two functions are only available with DSTC:
3. Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cor\
nering, by braking one or more
of the wheels if the car shows a tendency to skid or slide laterally. Th\
is is done by activating the Anti-
lock Braking System. A pulsating sound will be audible when the function\
is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is also one of the DSTC system's permanent functions and is not aff\
ected when the DSTC button on
the center control panel is pressed.
4. Emergency Brake Assistance (EBA)
The EBA function is an integrated part of the DSTC system. EBA is design\
ed to provide full brake
effect immediately in the event of sudden, hard braking. The system is a\
ctivated by the speed with which
you depress the brake pedal.
When the EBA system is activated, the brake pedal will go down and press\
ure in the brake system
immediately increases to the maximum level. Maintain full pressure on th\
e brake pedal in order to utilize
the system completely. EBA is automatically deactivated when the brake p\
edal is released.
When the car has been parked for some time, the brake pedal may sink mor\
e than usual when the engine
is started. This is normal and the pedal will return to its usual positi\
on when it is released.
* Standard on all models except the T5 turbo.
** Standard on the T5 turbo, option on all other models.

pattern, load-, speed-, traction-, temperature-, and treadwear rating. N\
ever drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire pressure label located inside the fuel filler door.
Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tir\
es should be rotated front-to-
back/back-to-front only. Tires must maintain the same direction of rotat\
ion throughout their lifetime, and
should never be rotated from one side of the vehicle to the other.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible, in accordance with "Tire Rotation" above\
. Do not drive on the temporary
spare at speeds above 50 m.p.h. (80km/h) or for distances greater than\
50 miles (80 km).
Never install snow chains on a temporary spare.

pg. 95 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid\
starts and stops and
adjusting the speed of your vehicle to immediate traffic conditions. Obs\
erve the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on
the accelerator pedal for the first few minutes of operation. A cold eng\
ine uses more fuel and is subject
to increased wear.
l Whenever possible, avoid using the car for driving short distances. This\
does not allow the engine to
reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the car.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc., increase air resistance and also \
fuel consumption.
l Avoid using automatic transmission kickdown feature unless necessary.
l Avoid using the air conditioning when it is not required. When engaged, \
the conditioner's compressor
places an additional load on the engine. However, at higher driving spee\
ds, fuel consumption will be

General information
Your vehicle is equipped with tires according to the tire information la\
bel on the inside of the fuel
filler door.
The following is an example of a tire designation code: 225/55 R16
225 = tire width in mm.
55 = tire profile. This is the relationship (in percent) between the sect\
ion height and width of the tire.
R = radial tires.
16 = diameter in inches.
The tires have good road holding characteristics and offer good handling\
on dry and wet surfaces. It
should be noted however that the tires have been developed to give these\
features on snow/ice-free
surfaces. Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher
degree of road holding on slippery surfaces than tires without the "all-\
season" rating. However,
for optimum road holding on icy or snow covered roads - we recommend suitable winter tires on all

Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l Special snow chains must be mounted on 215/55 R16. Consult your Volvo re\
tailer.
l 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. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained. Snow chai\
ns cannot be used on 17"
wheels.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models:Snow chains should only be installed on the front wheels. Only chains
adapted for AWD models should be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
l Check local regulations regarding the use of snow chains before installi\
ng.
l Always follow the chain manufacturer's installation instructions careful\
ly. Install chains as tightly as
possible and retighten periodically.
l Never exceed the chain manufacturer's specified maximum speed limit. In \
no case should you exceed
31 mph (50 km/h).
l Avoid bumps, holes or sharp turns when driving with snow chains.
l Vehicle handling can be adversely affected when driving with chains. Avo\
id fast maneuvering and
hard braking. Never allow the wheels to lock up during braking.
Snow tires, studded tires *
Tires for winter use:
Owners who live in or regularly travel through areas with sustained peri\
ods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain 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. Failure to do so could reduce traction to an \
unsafe level or adversely affect
handling. Volvo does not recommend tire rotation. However, as with any o\
ther radial tires, if rotated, the
tires must be kept on the same side of the car so that they revolve in t\
he same direction as before
rotation.
