2006 VOLVO S40 traction control

automatically after two minutes. This symbol may also light up in combination with other indicator or warning
symbols.
NOTE: The car can still be driven after the information symbol has come on. The car can be driven for 1-2 weeks
after service-related information has been displayed.
pg. 36 Symbols on the left side of the instrument panel
Symbols - left side of instrument panel
1. Malfunction indicator light
As you drive, a computer called On-Board Diagnostics II (OBDII) monitors your car's engine, transmission,
electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that
potentially may need correcting. When this happens, please have your car checked by a trained and qualified Volvo
service technician as soon as possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission controls, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
Canadian models are equipped with this symbol .
2. Anti-lock brake system (ABS)
If the warning light comes on, there is a malfunction of the ABS system (the standard braking system will still
function). The vehicle should be driven to a trained and qualified Volvo service technician for inspection. See page
107 for additional information. Canadian models are equipped with this symbol .
3. Rear fog light
This symbol indicates that the rear fog light (located in the driver's side tail light cluster) is on.
4. Stability system STC or DSTC
This indicator symbol flashes when the STC (Stability and Traction control system) or the DSTC (Dynamic
Stability and Traction control system) is actively working to stabilize the car. See page 109
for more detailed
information.
5. Not in use

12 volt socket, stability system, auxiliary equipment
12 volt sockets
The 12 volt sockets can be used to plug in certain accessories such as cellular telephones, etc. The key must be in
position I (or higher) for the auxiliary socket to function. The auxiliary sockets can also be used for cigarette lighters,
which are available at your Volvo retailer.
NOTE: The cover should be kept on when the auxiliary socket is not in use.
Stability system STC or DSTC
The stability system - Stability and Traction Control (STC), or the optional Dynamic Stability and Traction Control
(DSTC) - activate automatically when the car is started. In certain situations, it may be necessary to disable the
system's anti-spin function, for example, while driving for a short period with tires of different dimensions.
To disable the anti-spin function:
Press the STC
1 or DSTC button for approximately one second. The indicator light in the button will go out, and
STC/DSTC SPIN CONTROL OFF will be shown in the information display.
1. Models equipped with All Wheel Drive (AWD) have an integrated traction control function, and are not equipped
with an STC button. DSTC is optional.
WARNING!
The car's handling and stability characteristics will be altered with the anti-spin function disabled.
NOTE: The anti-spin function will be automatically reactivated when the engine is started.
Auxiliary equipment
The button to the right of the STC/DSTC button can be used for Volvo-installed optional or auxiliary equipment.

ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction
grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of cornering (turning)
traction.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 controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material 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 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.
pg. 129 Snow chains, snow tire, 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!
