VOLVO S40 2008 Owners Manual speed-, traction- , temperature-, and treadwear rating. Never drive on mixed tires, except for brief periods when the
temporary spare tire is in use.
Always use properly inflated tires of correct

speed-, traction- , temperature-, and treadwear rating. Never 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 a placard
located on the driver's side B-pillar (the structural member at the side of the vehicle, at the rear of the driver's door
opening). See also the tire inflation pressure tables beginning on page 172
.
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. (80 km/h).
Never install snow chains on a temporary spare.

Brake system
Brake circuit malfunction
The brake system is a hydraulic system consisting of two separate brake circuits. If a problem should occur in one of
these circuits, it is still possible to stop the vehicle with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will
be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are

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 maximum tractive force
1.
1Models equipped with All Wheel Drive (AWD) have an integrated traction control function that cannot be disabled. DSTC is optional on AWD
models.
Temporarily switching off Spin control
1. Turn the thumbwheel (A) on the left-side steering wheel lever until the STC/DSTC menu is displayed.
2. Hold down the RESET button (B) to toggle between STC/DSTC SPIN CONTROL ON or OFF.
NOTE
The message STC/DSTC SPIN CONTROL OFF indicates that the stability system's spin control function has
temporarily been switched off.
The stability control indicator light will illuminate and remain on until spin control has been reactivated.
The spin control function is automatically enabled each time the engine is started.
STC/DSTC ON indicates that all system functions are active.
Active yaw control - AYC (DSTC only)
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.

Stability system
This is one of the stability system's permanent functions and cannot be switched off.
WARNING
The car's handling and stability characteristics will be altered if the STC/DSTC system functions have been disabled.
STC/DSTC-related messages in the text window
" TRACTION CONTROL TEMPORARILY OFF " - The system has been temporarily switched off due to high brake
temperature and will automatically switch on again when the brakes have cooled.
" ANTI SKID SERVICE REQUIRED " - the system has been automatically disengaged due to a fault. A trained and
qualified Volvo service technician should check the system.

passenger vehicle tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance 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 properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.
180 07 Wheels and tires
Snow chains, snow tires, studded tires
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.
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
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. Failure 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 opportunity to seat properly in the tires. The tires should have the same rotational
direction throughout their entire lifetime.
