Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

CAUTION
•Bumper-attached trailer hitches must not be used on Volvos, nor should safetychains be attached to the bumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
• When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer, driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi- ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension
*The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument panelalong with a message. The automatic transmission selects the optimalgear for the current load and engine speed.
Steep inclines
Do not lock the automatic transmission into a higher gear than what the engine can handle
‒ it
is not always preferable to drive in high gears at low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.3. Put the gear selector in P.
4. Release the brake pedal.Put chocks behind the wheels when the vehicle is parked on a hill with a trailer attached.
Starting on a hill
1. Depress the brake pedal. 2. Put the gear selector in D.
3. Release the parking brake.
4. Release the brake pedal and start driving.

7. Connect the electrical cable to the nearest
12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other 12 V sockets are used while the compressoris running.
WARNING
Never leave children unattended in the vehicle while the engine is running. 8. Start the compressor by moving the switch to
the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc. form onthe tire, switch off the compressor immedi-ately. The vehicle should not be driven. Callroadside assistance to have the vehicle towedto a workshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
NOTE
When the compressor first starts, air pressure may temporarily increase up to 6 bar (88 psi)but should decrease again after approxi-mately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
10. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is too high,use the air release valve to release air.
WARNING
If the bottle is not removed in the correct order, sealant could spill out.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehicleshould not be driven. Call roadside assistanceto have the vehicle towed to a workshop forinspection/replacement of the tire. Volvo rec-ommends an authorized workshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
13. Put the protective hose cover onto the hose to help prevent leakage of any residual seal- ing compound. Return the equipment to thecargo compartment.

Inflate tires with the compressorincluded in the tire sealing system The vehicle's original tires can be inflated using the compressor in the tire sealing system.
1. The compressor must be switched off. Makesure that the switch is in the 0 (Off) position
and take out the electrical cable and the hose.
2. Unscrew the tire's valve cap and screw the hose's valve connector as far as possibleonto the valve. Be sure the air release valve on the com- pressor's hose is completely closed.
3. Connect the electrical cable to the nearest 12 V outlet and start the vehicle.
WARNING
Inhaling exhaust fumes could lead to serious injury. Never leave the engine running in anenclosed space or a space without sufficientventilation.
WARNING
Never leave children unattended in the vehicle while the engine is running.
4. Start the compressor by moving the switch to the I (On) position.
CAUTION
Risk of overheating. The compressor should not be running for longer than 10 minutes ata time.
5. Inflate the tire to the pressure specified on
the tire pressure decal on the driver's side door pillar. If the inflation pressure is toohigh, use the air release valve to release air.
6. Switch off the compressor. Remove the hose and the electrical cable.
7. Screw the valve cap back onto the tire.
NOTE
• After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
NOTE
The compressor is an electric device. Follow local regulations for disposal.
