NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engine shut-down, vehicle inclination, ambient tempera- ture, etc.) the message
No value availablewill be shown in the center display. This does not mean that anything is wrong in the vehi-
cle systems.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery and support battery. The rapidcharging function should not be used as thiscould damage the battery.
CAUTION
Failure to observe the following could cause the infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
• The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too many times, it will shorten its service life. The service life of the starter battery is affec- ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging. A starter battery that is always kept fully charged has the maximum service life.
Location
The start battery is located in the cargo compartment.
WARNING
If the starter battery is disconnected, the func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.

Support battery In addition to the start battery, vehicles equipped with the Start/Stop function also have a supportbattery.
Vehicles with the Start/Stop function are equip- ped with two 12-volt batteries ‒ a heavy-duty
start battery and a support battery that provides extra current during the Start/Stop function'sstart sequence.
The support battery is located in a box next to the spring strut in the engine compartment.
NOTE
• The higher the current consumption in the vehicle, the more the alternator has towork and the batteries have to becharged = increased fuel consumption.
• When the starter battery capacity hasdropped below the lowest permissiblelevel, the Start/Stop function is disen-gaged.
When the Start/Stop function is temporarily reduced due to high current consumption:
• The engine will auto-start, even if the driverdoes not lift their foot from the brake pedal.
The support battery does not normally requiremore service than the start battery. If you have any questions or concerns, consult a workshop ‒
an authorized Volvo workshop is recommended.
CAUTION
If the following is not observed, the Start/ Stop function may temporarily stop workingafter connection of an external starter batteryor battery charger: • The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.

Cleaning the leather upholstery
1. Apply the leather cleaner to a damp spongeand squeeze it until the cleaner foams.
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 stain and do not rub.
4. Dry the stain using a soft towel and let the leather dry completely.
Protecting the leather upholstery
1. Apply a small amount of leather protector toa cloth and then apply the protector to the leather using light circular movements.
2. Let it dry for approximately 20 minutes. Protecting the leather upholstery makes it better able to withstand sunlight's harmful UV rays.

Cleaning the leather steering wheel
Only use cleaning agents and car care products recommended by Volvo. Clean regularly andtreat stains immediately for best results. It isimportant to vacuum before using a cleaningagent.
Leather steering wheelLeather needs to breathe. Never cover the leather steering wheel with a plastic protector.Volvo Leather Care Kit 951 0251 and LeatherSoftener 943 7429 are recommended for clean-ing the leather steering wheel. First, remove dirt,dust, etc. with a damp sponge or cloth.
CAUTION
Sharp objects such as rings could damage the leather on the steering wheel.
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 steering wheel using a solution of 5% ammonia. Forblood stains, mix approximately 2 dl(1 cup) ofwater with 25 g (one ounce) of salt and wipethe stain.
Type 2 (grease, oil, sauces or chocolate)
1. Same procedure as for Type 1 stains.
2. Finish by wiping the wheel with an absorbent paper or towel. Type 3
(dry dirt or dust)
1. Remove the dirt/dust using a soft brush.
2. Same procedure as for Type 1 stains.

Changing rear window wipers
The wiper blades help remove water from the windshield and rear window. Along with thewasher fluid, they clean the glass and helpimprove visibility while driving. The windshieldand rear window wiper blades can be replaced.
Changing rear window wipers
Lift the wiper arm from the window and pull the lower section of the blade to the right.
1. Grasp the center of the wiper blade and
lift it from the window to the stop position.
NOTE
When the wiper arm is halfway folded out, it will stop in a locking position that helps pre-vent the arm from falling back onto the rearwindow. The wiper arm must be pulled pastthe locking position stop in order to changethe wiper blade.
2. Grip the lower part of the blade and pull
to the right until the blade loosens from the arm.
3. Press the new wiper blade until it clicks into place. Check to make sure the blade issecurely in place.
4. Fold the wiper arm back toward the window.
CAUTION
Check the blades regularly. Neglected main- tenance shortens the life of the blades.
