17 01 Safety
Supplemental Restraint System
Supplemental Restraint System (SRS)
As an enhancement to the three-point seat belts, your Volvo is equipped with a Supplemental Restraint System (SRS).
Volvo's SRS consists of seat belt pretensioners, front airbags, side impact airbags, the occupant weight sensor, and
inflatable curtains. All of these systems are monitored by the SRS control module. An SRS warning light in the
instrument panel (see the illustration) illuminates when the ignition key is turned to position I, II, or III, and will
normally go out after approximately 7 seconds if no faults are detected in the system.
Where applicable, a text message will also be displayed when the SRS warning light illuminates. If this warning
symbol is not functioning properly, the general warning symbol
illuminates and either SRS AIRBAG SERVICE
URGENT or SRS AIRBAG SERVICE REQUIRED will be displayed.
WARNING
If the SRS warning light stays on after the engine has started or if it illuminates while you are driving, have the
vehicle inspected by a trained and qualified Volvo service technician as soon as possible.
Never try to repair any component or part of the SRS yourself. Any interference in the system could cause
malfunction and serious injury. All work on these systems should be performed by a trained and qualified Volvo
service technician.
WARNING
If your vehicle has been subjected to flood conditions (e.g. soaked carpeting/standing water on the floor of the
vehicle) or if your vehicle has become flood-damaged in any way, do not attempt to start the vehicle or put the key
in the ignition before disconnecting the battery (see below). This may cause airbag deployment which could result in
personal injury. Have the vehicle towed to a trained and qualified Volvo service technician for repairs.
Automatic transmission
Before attempting to tow the vehicle, use the following procedure to override the shiftlock system to move the gear
selector to the neutral position:
Switch off the ignition for at least 10 minutes and disconnect the battery
Wait at least one minute.
Insert the key in the ignition and turn it to position II.
Press firmly on the brake pedal.
Move the gear selector from Park ( P) to the Neutral ( N) position. See page 145 for information on manually
ProCarManuals.com

If the vehicle has been involved in a collision, the text CRASH MODE SEE MANUAL may appear in the information
display. This indicates that the vehicle's functionality has been reduced.
NOTE
This text can only be shown if the display is undamaged and the vehicle's electrical system is intact.
CRASH MODE is a feature that is triggered if one or more of the safety systems (for example, front or side airbags,
an inflatable curtain, or one or more of the seat belt pretensioners) has deployed. The collision may have damaged an
important function in the vehicle, such as the fuel lines, sensors for one of the safety systems, the brake system, etc.
WARNING
Never attempt to repair the vehicle yourself or to reset the electrical system after the vehicle has displayed
CRASH MODE SEE MANUAL. This could result in injury or improper system function.
Restoring the vehicle to normal operating mode should only be done by a trained and qualified Volvo service
technician.
After CRASH MODE SEE MANUAL has been displayed, if you detect the odor of fuel vapor, or see any signs of
fuel leakage, do not attempt to start the vehicle. Leave the vehicle immediately.
Attempting to start the vehicle
If damage to the vehicle is minor and there is no fuel leakage, you may attempt to start the vehicle. To do so:
1. Remove the ignition key or optional keyless drive start control (see page 138
).
2. Reinsert the key or start control in the ignition switch. The vehicle will then attempt to reset CRASH MODE to
normal mode.
3. Try to start the vehicle.
Moving the vehicle
If the electrical system is able to reset system status to normal (CRASH MODE SEE MANUAL will no longer be
displayed), the vehicle may be moved carefully from its present position, if for example, it is blocking traffic. It
should, however, not be moved farther than is absolutely necessary.
WARNING
Even if the vehicle appears to be drivable after CRASH MODE has been set, it should not be driven or towed
(pulled by another vehicle). There may be concealed damage that could make it difficult or impossible to control.
The vehicle should be transported on a flatbed tow truck to a trained and qualified Volvo service technician for

NOTE
Front park assist is disengaged automatically when the parking brake is applied.
If the vehicle is equipped with front and rear park assist, both systems will be deactivated by pressing the button.
Audible signals from the park assist system
The Park Assist system uses an intermittent tone that pulses faster as you come close to an object, and becomes
constant when you are within approximately 1 ft (30 cm) of an object in front of or behind the vehicle. If the volume
of another source from the audio system is high, this will be automatically lowered.
If there are objects within this distance both behind and in front of the vehicle, the signal alternates between front and
rear speakers.
Faults in the system
If the information symbol illuminates and PARK ASSIST SERVICE REQUIRED is shown on the information
display, this indicates that the system is not functioning properly and has been disengaged. Consult a trained and
qualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.

Cleaning the sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with water and a suitable car
washing detergent.
NOTE

NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
Exterior components
Volvo recommends the use of special cleaning products, available at your Volvo retailer, for cleaning colored plastic,
rubber, or ornamental components such as chromed strips on the exterior of your vehicle. The instructions for using
these products should be followed carefully.Solvents or stain removers should not be used.
CAUTION
Avoid waxing or polishing plastic or rubber components
Polishing chromed strips can wear away or damage the surface
Polishes containing abrasive substances should not be used
193 08 Car care
Washing and cleaning the car
NOTE
During high pressure washing, the spray mouthpiece must never be closer to the vehicle than 13" (30 cm). Do not
spray into the locks.
Dirt, snow, etc., on the headlights can reduce lighting capacity considerably. Clean the headlights regularly, for
example when refueling.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components
or toward the rear side of the engine. Special moonroof cautions:
Always close the moonroof and sun shade before washing your vehicle.
Never use abrasive cleaning agents on the moonroof.
Never use wax on the rubber seals around the moonroof
Automatic washing - simple and quick
We do NOT recommend washing your car in an automatic wash during the first six months (because the paint will not
have hardened sufficiently). An automatic wash is a simple and quick way to clean your car, but it is worth
remembering that it may not be as thorough as when you yourself go over the car with sponge and water. Keeping the
underbody clean is most important, especially in the winter. Some automatic washers do not have facilities for washing
the underbody.
CAUTION
Before driving into an automatic car wash, turn off the optional rain sensor to avoid damaging the windshield
wipers.
Make sure that side view mirrors, auxiliary lamps, etc, are secure, and that any antenna(s) are retracted or
removed. Otherwise there is risk of the machine dislodging them.
Chromed wheels : Clean chrome-plated wheels using the same detergents used for the body of the vehicle.
Aggressive wheel-cleaning agents can permanently stain chrome-plated wheels.
WARNING
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
