Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires."
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see age 188 for the
location of the washer fluid reservoir). This is important since dirt is often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. Volvo Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water Down to 5° F (-15° C): 1 part washer solvent and 3
parts water Down to 0° F (- 18° C): 1 part washer solvent and 2 parts water Down to -18° F (-28° C): 1 part washer
solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de -icing sprays as they can cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio
system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This
position reduces drain on the battery.
Please keep in mind that using systems, accessories, etc that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12-volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.
NOTE
If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel
when the battery charge is low.
An energy conserving function designed into the vehicle's electrical system will switch off certain functions or
reduce the load on the battery by, e.g., reducing the audio system's volume.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer before driving long distances. Your retailer
will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for your use in the event that problems
occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked1.
Check condition of drive belts.
Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by your Volvo retailer only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with your Volvo retailer if you intend to drive in countries where it may be difficult to obtain the
correct fuel.
Consider your destination. If you will be driving through an area where snow or ice are likely to occur, consider
snow tires.

2. Steer the vehicle in the direction of travel and keep the brake pedal depressed.
Electronic Brake Force Distribution (EBD)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. Please be aware
that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not
shorten stopping distances on slippery surfaces.
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a Volvo retailer for inspection.
WARNING
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest Volvo workshop to have the brake
system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. Maintain full pressure on the brake pedal in order to utilize the system completely.
EBA is automatically deactivated when the brake pedal is released.
NOTE
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically deactivated when the brake
pedal is released.
When the vehicle has been parked for some time, the brake pedal may sink more than usual when the engine is
started. This is normal and the pedal will return to its usual position when it is released.

Stability system
Stability Traction Control (STC)/Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help reduce wheel spin, counteract skidding, and to
generally help improve directional stability.
A pulsating sound will be audible when the system is actively operating and is normal.

Exterior plastic components
Cleaning exterior plastic components should be done with a cleaning agent specially designed for this purpose.
Solvents or stain removers should not be used. Consult your Volvo retailer.
NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
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.
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
177 08 Car care
Washing and cleaning the car
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
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
Exterior lighting
Condensation may form temporarily on the inside of the lenses of exterior lights such as headlights, fog lights, or
taillights. This is normal and the lights are designed to withstand moisture. Normally, condensation will dissipate after
the lights have been on for a short time.
