Towing recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.

CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
WARNING
•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.
Trailer turn signals and brake lightsIf one (or more) of the bulbs on a trailer is defec-tive, a symbol and a message will be displayed inthe instrument panel. The other lights on the trailer must be checked manually by the driver before the vehicle is driven.See the subsection "Manual check" in the follow-ing section "Trailer lamp check".

Battery drain Your vehicle's electrical functions drain the bat- tery to varying extents.
Avoid using ignition mode II as much as posssi-
ble, or electrical functions that require a great deal of electrical current when the engine is notrunning. Using ignition mode I whenever possible con-
sumes less electrical current. Functions that require a great deal of electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current. If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

Automatically connecting to a workshop
Without driver confirmation
This is the most convenient way to transmit trou- ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion. If the vehicle stops at a workshop and the engine is switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driver does not tap the
Cancel button in the message.
To help prevent the driver from being disturbed by unwanted requests to connect (e.g., if thevehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmation
With this alternative, the driver must confirm a connection. If the vehicle stops at a workshop and the engine is switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv- er's door is opened if the driver taps
Connect in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt will be made to establish a connection.
NOTE
To help prevent the driver from being distur- bed by unwanted requests to connect (e.g., ifthe vehicle is often parked near a workshopwith an authorized Volvo network), the vehiclewill switch to manual connection if the drivercancels a connection request twice within5 days.
Manually connecting to a workshopManual connections are handled by the service technician.
Changing the way a connection is madeThe type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view and

WARNING
• The cooling fan (located at the front of the engine compartment, behind the radi-ator) may start or continue to operate (forup to 6 minutes) after the engine hasbeen switched off.
• Engine cleaning should only be done by aworkshop. If engine cleaning agents areused when the engine has been running,there may a fire risk.
• Before performing any operations in theengine compartment, the ignition shouldalways be completely switched off (in mode
0) and there should be no remote
keys in the passenger compartment. Thegear selector should be in the P (park)
position. If the engine has been running, wait until it has cooled before touchingany components in the engine compart-ment.
• The distributor ignition system operatesat very high voltages. Special safety pre-cautions must be followed to preventinjury. Always turn the ignition off whenreplacing distributor ignition componentse.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.
