CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

Tire Pressure Monitoring System (TPMS) TPMS provides a warning if inflation pressure in one or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses the rotational speed of the tires in combination with signal analysis of the ABS sen-sor signals to determine if they are properly infla-ted. When a tire is under-inflated, its diameter(and consequently also its rotational speed)changes. By comparing the individual tires witheach other it is possible to determine if one ormore tires are under inflated. If inflation pressureis too low, an indicator symbol will illuminate inthe instrument panel and a text message will bedisplayed.
Symbol
Explanation
The symbol illuminates to indicate low tire inflation pressure. If a malfunction occurs in the sys- tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale.

Start battery
The vehicle's electrical system is single pole and uses the body and engine block as conductors. 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 an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles to support electrical systems andfunctions and regenerative charging. 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

WARNING
In certain models, the battery is held in place by a strap. Ensure that this strap is alwayssecurely fastened and pulled taut.
• When replacing the start battery or support battery an Absorbed Glass Mat (AGM) mustbe used.
• When replacing the start battery, a new bat-tery with the same specifications and dimen-sions must be used. The battery should onlybe replaced by a trained and qualified Volvoservice technician.

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:
Current (V) 12 Cold start capacity (Cold Cranking Amperes -CCA) (A) 170
Dimensions, L×W×H in. (mm)5.9×3.5×5.1
(150×90×130)
Capacity (Ah) 10
• 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 brakepedal is depressed.
The support battery does not normally requiredmore service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.

Leather * careVolvo'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 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 upholstery
1. 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 upholstery
1. Put a small amount of protectant cream on acloth 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 spongeand 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. Type 3
(dry soil or dust)
1. Remove the soil/dust with a soft brush.
2. Same procedure as for type I stains.
CAUTION
Sharp objects, such as rings, could damage the leather on the steering wheel.
Leather panels *Leather should be allowed to breath. Never cover the upper side of the dashboard or door panelswith a plastic protector. Ask your Volvo retailerabout Leather Care Kit 951 0251 and LeatherSoftener 943 7429.
Spots on interior plastic, metal, or wood
surfaces
Cleaning interior plastic components should bedone with a moist microfiber cloth. Consult yourVolvo retailer.
