When the battery is being charged with the electric motor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of 150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is usedto augment braking. This is indicated in theinstrument panel with the pointer down in thered area.

WARNING
If the warning symbols for both brake fault and ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is nor- mal when this occurs, drive carefully tothe nearest workshop to have thebrake system checked - an authorizedVolvo workshop is recommended.
If the brake fluid has fallen below theMIN
level in the brake fluid reservoir,
the vehicle should not be driven untilthe brake fluid has been filled. The rea-son for the brake fluid loss must bechecked.

Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.

Brakes (p. 403)
Braking on wet roads
Prolonged driving in heavy rain without brak- ing may cause braking effect to be slightlydelayed the first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pres-sure to the brake pedal. You should thereforemaintain a greater distance to the vehicleahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helpswarm up the brake discs, enabling them to drymore quickly and protecting them against cor-rosion. Consider the current traffic situationwhen braking.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

How can I prepare for my next OBD II
emission inspection?
If your Check Engine (MIL) light is lit or was lit but went out without service, haveyour vehicle diagnosed and, if necessary,serviced by a qualified Volvo technician.
If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.Two half-hour trips of mixed stop-and-go/highway driving are typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and inter-vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the vehicle 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 fluidlevels are between the indicated "min"and "max" markings.
Clean interior glass surfaces with a glasscleaner and soft paper towels.
Wipe driver information displays with asoft cloth.
Visually inspect battery terminals for cor-rosion. Corrosion may indicate a loose ter-minal connector, or a battery near the endof its useful service life. Consult your Volvoretailer for additional information.
As needed:
Wash the vehicle, including the undercarriage, to reduce wear that can be caused by abuildup of dirt, and corrosion that can becaused by salt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other pla-ces where they may collect.
