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.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual.Press (hold) down the brake pedal as longas necessary. When the brake pedal is released, all brak- ing ceases.

Brakes (p. 383)
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.

All Wheel Drive (AWD) *
All-wheel drive (AWD 8
), also called four-
wheel drive, means that power is distributed to all four wheels, which improves traction.
To achieve the best traction, power is auto- matically directed to the wheels that have thebest grip. The system continuously calculatesthe need for torque to the rear wheels, andcan immediately redistribute up to half of theengine's torque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions,most of the engine's power is directed to thefront wheels. When the vehicle is stationary,all-wheel drive is always activated in prepara-tion for maximum traction during acceleration. All-wheel drive reacts differently depending on which drive mode is selected.

Self-leveling and suspension functions are controlled automatically.
Rear leveling control keeps the rear section of the vehicle at the same height regardless ofload. Leveling control may also remain activewhen the vehicle is parked.
Shock absorbers (Four-C)On vehicles equipped with Four-C, the shockabsorbers are adapted to the selected drive mode and the current vehicle speed. Theshock absorbers are normally set to help opti-mize comfort and are adjusted continuouslyaccording to the road surface and the vehicle'sacceleration, braking and cornering.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspension
may occur during transport, which couldadversely affect the lashing and result in dam-age.

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.

Driving through standing water
It may be necessary to drive the vehicle through standing water, e.g. deep puddles orflooding on the road. This must be done withgreat caution.
The vehicle can be driven through water up to a depth of 25 cm (9 in) at no more than walk-ing speed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When youhave passed the water, press lightly on thebrake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc.can make the brake linings slippery, resultingin delayed braking effect. If the vehicle is equipped with contacts for an electric heater or trailer coupling, cleanthese after driving in water or mud.
Do not allow the vehicle to stand in waterup to the sills any longer than absolutelynecessary. This could result in electricalmalfunctions.
CAUTION
Engine damage could occur if water enters the air cleaner.
If water enters the transmission, thelubricating ability of the oils is reducedand the service life of these systems isshortened.
Damage to any component, engine,transmission, turbocharger, differentialor its internal components caused byflooding, vapor lock or insufficient oil isnot covered under warranty.
If the engine stalls while the vehicle isin water, do not attempt to restart it.Have the vehicle towed out of thewater to a workshop. An authorizedVolvo workshop is recommended. Riskof engine failure.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.

Recommended tire pressure
The tire pressure placard on the driver's side B pillar (between the front and the rear door)indicates tire pressure for different loads andspeed conditions.
The decal specifies the designation for the fac- tory-mounted tires on the vehicle, as well asload limits and inflation pressures.

Tire pressure monitoring system

The tire pressure monitoring system 6
pro-
vides a warning symbol in the instrument panel if pressure is too low in one or moretires.
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbol
will flash for approximately one minute andthen glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determineif the tires are properly inflated. If inflationpressure in a tire is too low, its diameter (andconsequently its rotational speed) changes. Bycomparing the tires with each other, the sys-tem can determine if the pressure in one ormore tires is too low.
General information about the tire pressure monitoring system
In the following description, the tire monitor- ing system is generally referred to as TPMS. Each tire, including the spare (if provided) 7
should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size thanthe size indicated on the vehicle placard or tireinflation pressure label, you should determinethe proper tire inflation pressure for thosetires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illumi-nates, you should stop and check your tires assoon as possible, and inflate them to theproper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tirefailure. Under-inflation also reduces fuel effi-ciency and tire tread life, and may affect thevehicle's handling and stopping ability. Pleasenote that the TPMS is not a substitute forproper tire maintenance, and it is the driver'sresponsibility to maintain correct tire pressure,even if under-inflation has not reached thelevel to trigger illumination of the TPMS lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when

Volvo's leather upholstery * is treated to pro-
tect its original appearance. Over time, sun- light, grease, dirt, etc. could break down theprotective layer. This could result in scratchesand cracking. Leather upholstery * is a natural product that
changes and acquires a beautiful patina over time. Regular cleaning and treatments arerequired to preserve the qualities and color ofthe leather. Volvo offers a comprehensiveproduct, Volvo Leather Care KitWipes, forcleaning and treating leather upholstery.When used as directed, it helps preserve theleather's protective coating. For optimal results, Volvo recommends clean- ing and applying protective cream one to fourtimes a year (or more often as needed). VolvoLeather Care Kit 951 0251 and Volvo LeatherSoftener 943 7429 are available for purchaseat Volvo retailers.
Cleaning the leather upholstery1. Apply the leather cleaner to a damp sponge and squeeze it until the cleanerfoams. 2. Move the sponge in circular motions to
apply the foam to the stain.
3. Dampen the stain thoroughly with the sponge. Let the sponge absorb the stainand do not rub.
4. Dry the stain using a soft towel and let the leather dry completely.
Protecting the leather upholstery1. Apply a small amount of leather protectorto a cloth and then apply the protector tothe leather using light circular movements.
2. Let it dry for approximately 20 minutes. > Protecting the leather upholsterymakes it better able to withstand sun-light's harmful UV rays.
