to spin, an electronically controlled coupling distributes power to the \
wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
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 pr\
operly inflated tires of correct
dimensions. Tire size and inflation pressures are shown on the tire pres\
sure 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, lowspeed, short-distance use \
only. Replace it with a full-sized
tire as soon as possible, in accordance with "Tire Rotation" in the prev\
ious paragraph. Do not drive on
the temporary spare at speeds above 50 m.p.h. (80km/h) or for distance\
s greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

improve tractive force. Under certain circumstances, such as when drivin\
g with snow chains, or driving
in deep snow or loose sand, it may be advisable to temporarily switch of\
f this function for maximum
tractive force. This is done by pressing the DSTC button on the center c\
ontrol panel for at least a half a
second.
When the SC function has been switched off:
l The text window will briefly display "DSTC SPIN CONTROL OFF"
l The LED in the DSTC button will be off.
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 vehicle shows a tendency to skid or slide laterally\
. This is done by activating the
Anti-lock Braking System. A pulsating sound will be audible when the fun\
ction 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. Roll Stability Control (RSC)
RSC utilizes a gyro-sensor to monitor the vehicle's angle of inclination\
, and the rate at which this angle
changes. If necessary, RSC activates the Anti-lock Brake System to brake\
one or more of the wheels to
help maintain stability. A pulsating sound will be audible when the func\
tion 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 one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.

Dynamic Stability Traction Control (DSTC) (contd)
The DSTC button
The DSTC button in the center control panel is used to switch the Spin C\
ontrol (SC) function on or off.
The button must be pressed for at least a half second to prevent SC from\
being switched off
inadvertently.
When the system has been switched off, the green indicator lamp in the b\
utton will go out and "DSTC
SPIN CONTROL OFF" will be displayed in the text window.

CAUTION
The vehicle must not be driven with wheels of different dimensions or wi\
th a spare tire other than the
one that came with the vehicle. The use of different size wheels can ser\
iously damage your vehicle's
transmission.
pg. 115 Wheels and tires
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 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.
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.
NOTE: Consult your Volvo retailer for additional snow chain information.
CAUTION
- Check local regulations regarding the use of snow chains before instal\
ling.
- Always follow the chain manufacturer's installation instructions caref\
ully. 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 wit\
h 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 per\
iods 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 retai\
n traction during cornering, braking,
and accelerating. Failure to do so could reduce traction to an unsafe le\
vel or adversely affect handling.
Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.

l With warm tires, correct only when the pressure is too low. The tire tem\
perature rises after driving
just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loa\
ds when inflated as
recommended on the tire information label located on the inside of the f\
uel filler door. This label lists
both tire and vehicle design limits. Do not load your vehicle beyond the\
load limits indicated.
WARNING!
Improperly inflated tires will reduce tire life, adversely affect vehicl\
e handling and can possibly lead
to failure resulting in loss of vehicle control without prior warning.
Temporary Spare
The spare tire in your vehicle is called a "Temporary Spare".
Recommended tire pressure (see decal on Fuel filler door) should be ma\
intained irrespective which
position on the vehicle the Temporary Spare tire is used on. In the even\
t of damage this tire, a new one
can be purchased from your Volvo retailer.
WARNING!
Current legislation prohibits the use of the Temporary Spare" tire other\
than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e by a standard tire. Road
holding and handling may be affected with the "Temporary Spare" in use. \
Do not exceed 50 mph (80
km/h). Do not drive farther than 50 miles (80 km) on a temporary spar\
e tire.
CAUTION
The vehicle must not be driven with wheels of different dimensions or wi\
th a spare tire other than the
one that came with the vehicle. The use of different size wheels can ser\
iously damage your vehicle's
transmission.
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" in th\
e previous paragraph. Do not drive
on the temporary spare at speeds above 50 m.p.h. (80km/h) or for dista\
nces greater than 50 miles (80
km). Never install snow chains on a temporary spare.
NOTE: Certain models may be equipped with a full-size spare tire. When used, i\
t should be inflated to
the same pressure as the tire it is replacing.
