W - Winter/Wet driving mode - enhanced vehicle traction
Press the button at the base of the gear selector to engage/disengage th\
is driving mode (see illustration).
l Mode W will only function if the gear selector is in the (D)rive position.
l When the W driving mode is engaged, this is displayed in the instrument \
panel (see page 46).
This mode may be selected for starting/ moving off on slippery roads.
1. Six-speed transmission: gears 2, 3, 4, 5, and 6.

All Wheel Drive (option)
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is distributed
automatically between the front and rear wheels. Under normal driving co\
nditions, most of the engine's power is directed
to the front wheels. However, if there is any tendency for the front whe\
els 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. Never drive on m\
ixed 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 inflation
pressure placards, located on the driver's side B-pillar (the structura\
l member at the side of the vehicle, at the rear of the
driver's door opening), or on the inside of the fuel filler door on Can\
adian models.
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. 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.

Stability system
Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help red\
uce wheel spin, counteract skidding, and to
generally help improve directional stability.
NOTE: 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 powe\
r 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 DSTC's permanent functions and cannot be switched off.
Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the vehicle is accelerating.
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 maximum tractive f\
orce.
Temporarily switching off Spin control
- Turn the thumbwheel (1) on the left-side steering wheel lever until \
the DSTC menu is displayed.
- Hold down the RESET button (2) to toggle between DSTC SPIN CONTROL O\
N or OFF.
NOTE:
l The message DSTC SPIN CONTROL OFF indicates that the stability system's \
spin control function has temporarily
been switched off.
l The stability control indicator light will illuminate and remain on until spin control has been reactivated.
l The spin control function is automatically enabled each time the engine \
is started.
l DSTC ON indicates that all system functions are active.
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 one of DSTC's permanent functions and cannot be switched off

General information
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation placard on the B-pillar
(the structural member at the side of the vehicle, at the rear of the d\
river's door opening), or on the inside
of the fuel filler door on Canadian models.
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

WARNING!
The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing\
the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under c\
ontrolled conditions on a specified
indoor laboratory test wheel. Sustained high temperature can cause the m\
aterial of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire \
failure. The grade C corresponds
to a minimum level of performance that all passenger vehicle tires must \
meet under the Federal Motor
Safety Standard No. 109. Grades B and A represent higher levels of perfo\
rmance on the laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is pr\
operly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading, either separatel\
y or in combination, can cause
heat buildup and tire failure.

Snow chains, snow tires, studded 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 fron\
t wheels. Only chains
adapted for AWD models should be used.
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:
l 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.
l 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 level or adversely affect
handling.
l Do not mix tires of different design as this could also negatively affec\
t overall tire road grip.
l Winter tires wear more quickly on dry roads in warm weather. They should\
be removed when the
winter driving season has ended.
l Studded tires should be run-in 300-600 miles (500-1000 km) during whic\
h the vehicle should be
driven as smoothly as possible to give the studs the opportunity to seat\
properly in the tires. The tires
should have the same rotational direction throughout their entire lifeti\
me.
NOTE: Please consult state or provincial regulations restricting the use of s\
tudded winter tires before
installing such tires.

pg. 165 Wheels and tires
Temporary spare
The spare tire in your vehicle is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fu\
el filler door) should be
maintained irrespective of which position on the vehicle the temporary s\
pare tire is used.
In the event of damage to this tire, a new one can be purchased from you\
r Volvo retailer.
