2008 VOLVO S40 lights

The system is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates.
The front park assist system is active from the time the engine is started until the vehicle exceeds a speed of
approximately 10 mph (15 km/h). It is also active when the vehicle is backing up.
Rear park assist is active when the engine is running and reverse gear has been selected.
Rear park assist
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comes from the rear speakers.
The system must be deactivated when towing a trailer, carrying bicycles in a rear-mounted carrier, etc, which could
trigger the rear park assist system's sensors.
NOTE
Rear park assist is deactivated automatically when towing a trailer if Volvo genuine trailer wiring is used.
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.

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
ProCarManuals.com

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.
Polishing and Waxing
Normally, polishing is not required during the first year after delivery, however, waxing may be beneficial.
Before applying polish or wax the vehicle must be washed and dried. Tar spots can be removed with kerosene or tar
remover. Difficult spots may require a fine rubbing compound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax.
Waxing alone does not substitute for polishing a dull surface.
A wide range of polymer-based waxes can be purchased today. These waxes are easy to use and produce a long-
lasting, high-gloss finish that protects the bodywork against oxidation, road dirt and fading.
194 08 Car care
Washing and cleaning the car
Do not polish or wax your vehicle in direct sunlight (the surface of the vehicle should not be warmer than 113° F
(45° C).
CAUTION
Volvo does not recommend the use of long-life or durable paint protection coatings, some of which may claim to
prevent pitting, fading, oxidation, etc. These coatings have not been tested by Volvo for compatibility with your
vehicle's clear coat. Some of them may cause the clear coat to soften, crack, or cloud. Damage caused by application
of paint protection coatings may not be covered under your vehicle's paint warranty.
Upholstery care
Fabric
Clean with soapy water or a detergent. For more difficult spots caused by oil, ice cream, shoe polish, grease, etc., use a
clothing/fabric stain remover. Consult your Volvo retailer.
Interior plastic components
Cleaning interior plastic components should be done with a cleaning agent specially designed for this purpose. Consult
your Volvo retailer.
Alcantera™ suede-like material
Suede -like upholstery can be cleaned with a soft cloth and mild soap solution.
Leather care
Volvo's leather upholstery is manufactured with a protectant to repel soiling. Over time, sunlight, grease and dirt can
break down the protection. Staining, cracking, scuffing, and fading can result.
Volvo offers an easy-to-use, non-greasy leather care kit formulated to clean and beautify your vehicle's leather, and to
renew the protective qualities of its finish. The cleaner removes dirt and oil buildup. The light cream protectant
restores a barrier against soil and sunlight.

Each time the car is refueled:
Check the engine oil level
Clean the windshield, windshield wipers, headlights, and taillights
Monthly:
Check cold tire pressure in all tires. Inspect the tires for wear.
Check that engine coolant and other fluid levels are between the indicated "min" and "max" markings.
Clean interior glass surfaces with a glass cleaner and soft paper towels.
Wipe driver information displays with a soft cloth.
Visually inspect battery terminals for corrosion. Corrosion may indicate a loose terminal connector, or a battery near
the end of its useful service life. Consult a trained and qualified Volvo service technician for additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that
can be caused by salt residues.
Clean leaves and twigs from air intake vents at the base of the windshield, and from other places where they may
collect.

Emission inspection readiness
What is an Onboard Diagnostic System (OBD II)?
OBD II is part of your vehicle's computerized engine management system. It stores diagnostic information about your
vehicle's emission controls. It can light the Check Engine light (MIL) if it detects an emission control "fault." A "fault"
is a component or system that is not performing within an expected range. A fault may be permanent or temporary.
OBD II will store a message about any fault.
How Do States Use OBD II for Emission Inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can then read "faults." In some
states, this type of inspection has replaced the tailpipe emission test.
How Can My Vehicle Fail OBD II Emission Inspection ?
Your vehicle can fail OBD II emission inspection for any of the following reasons.
If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
If your vehicle's Check Engine light was lit, but went out without any action on your part, OBD II will still have a
recorded fault. Your vehicle may pass or fail, depending on the inspection practices in your area.
If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete
and "not ready" for inspection. A vehicle that is not ready may fail inspection.

WARNING
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
