All Wheel Drive (AWD) 11
Your Volvo can be equipped with All Wheel Drive, which means that power is distributedautomatically between the front and rear wheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction. AWD reacts differently, depending on the drive mode * selected.

Suspension and leveling control
*
The leveling control system adjusts the suspen- sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock absorbers
This system is linked to the selected drive mode and is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering. A message will be displayed in the instrument panel when the suspension level is beingadjusted. The level cannot be adjusted if one of the side doors or the hood is open.
Suspension leveling settings
Easy entryThe vehicle can be lowered to entering and exit- ing easier. Select

Start battery
The start (main) battery is used to power the starter motor and other electrical componentsand systems. The start battery should only be replaced by a trained and qualified Volvo service technician.
The vehicle has an alternating current generator. The start battery is called an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles with carbon dioxide-reducingfunctions such as Start/Stop and regenerativecharging, and to support the vehicle's variouselectrical systems and functions. The service life of a battery is affected by factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:

• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
• When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa- bled due to high current consumption:
• The engine will auto-start, even if the brake pedal is depressed.
The support battery does not normally required more service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery or a battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery. To help ensure auto-start, the start battery should be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours. If a charger is not available, it is advisable to disable the Start/Stop function until the bat-tery is sufficiently recharged.

Cleaning the interior
Only use cleaning agents and car care products recommended by Volvo. Clean regularly and fol-low the instructions included with the car careproduct.
CAUTION
• Under no circumstances should gasoline, naphtha or similar cleaning agents beused on the plastic or the leather sincethese can cause damage.
• Take extra care when removing stainssuch as ink or lipstick since the coloringcan spread.
• Use solvents sparingly. Too much solventcan damage the seat padding.
• Start from the outside of the stain andwork toward the center.
• Sharp objects (e.g. pencils or pens in apocket) or Velcro fasteners on clothingmay damage the textile upholstery.
• Clothing that is not colorfast, such asnew jeans or suede garments, may stainthe upholstery.
Fabric upholstery and ceiling linerClean with soapy water or a detergent. For more difficult spots caused by oil, ice cream, shoe pol-ish, grease, etc., use a clothing/fabric stainremover. Consult your Volvo retailer.
Leather
* careVolvo's leather upholstery is manufactured with aprotectant 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 yourvehicle's leather, and to renew the protectivequalities of its finish. The cleaner removes dirtand oil buildup. The light cream protectantrestores a barrier against soil and sunlight. Volvo also offers a special leather softener that should be applied after the cleaner and protec-tant. It leaves leather soft and smooth, andreduces friction between leather and other fin-ishes in the vehicle. Volvo recommends cleaning, protecting and con- ditioning your vehicle's leather two to four times ayear. Ask your Volvo retailer about Leather CareKit 951 0251 and Leather Softener 943 7429.
Cleaning leather upholstery1. Pour leather cleaner on a damp sponge and
squeeze it until the cleaner foams.
2. Apply the foam to the stain by moving the sponge with circular movements.
3. Dampen the stain thoroughly with the sponge. Let the sponge absorb the stain, do not rub.
4. Dry the stain with soft paper towels or a towel, and allow the leather to dry completely.
Protecting leather upholstery1. Put a small amount of protectant cream on a cloth and apply a thin coating of cream to the upholstery with light circular movements.
2. Allow the leather to dry for 20 minutes. This will help the leather resist staining and pro- tect against sunlight's harmful UV rays.
Cleaning a leather-covered steering wheel
• Remove soil, dust, etc., with a damp sponge and a neutral soap solution.
• Leather should be allowed to breath. Nevercover the steering wheel with a plastic pro-tector.
• Volvo recommends cleaning, protecting andconditioning the steering wheel with Volvo'sLeather Care Kit 951 0251 and LeatherSoftener 943 7429.
If there are stains on the steering wheel: Type 1 (ink, wine, coffee, milk, sweat or blood)
–Use a soft cloth or sponge. Wipe the wheel with a solution with 5% ammonia. For bloodstains, mix approx. 1 cup (2 dl) of water andone ounce (25g) of salt and wipe the stain.
Type 2 (fat, oil, sauces, or chocolate)
1. Same procedure as for type I stains.
2. Finish by rubbing the wheel with absorbent paper or a towel.
