476Towing using a towline
This section refers to one vehicle being towed
behind another using a towline.
Twin Engine vehicles may not be towed behind
another vehicle due to the risk of damage to the
electric motor. If the vehicle cannot be driven and
needs to be moved, it must be transported on a
tow truck with all four wheels on the bed of the
truck.
Towing another vehicleTowing another vehicle requires a lot of power -
use the AWD drive mode. This helps charge the
hybrid battery and improve the vehicle's driving
and roadholding characteristics.
Before towing another vehicle, check applicable
speed limit regulations.
Jump startingDo not tow the vehicle to start the engine. Use an
auxiliary battery if the start battery's charge level
is so low that the engine cannot be started.
CAUTION Attempts to tow-start the vehicle could cause
damage to the electrical drive motor and
three-way catalytic converter.

The cover turns along its center line and
can then be removed. 3. Screw in the towing eyelet until it reaches its
stop. Fasten the eyelet securing by, for exam-
ple, inserting a lug wrench* through it and
using this as a lever.
CAUTION It is important that the towing eye is screwed
in securely as far as possible.
Removing the towing eyelet:
–
After use, unscrew the towing eyelet and
return it to its storage location.
Replace the cover on the bumper.

This section refers to transporting the vehicle
with a tow truck or similar vehicle. Call a professional towing service for assistance.
In certain conditions, the towing eyelet can be
used to pull the vehicle onto a flatbed tow truck.
CAUTION Note that vehicles with Twin Engine must
always be towed raised with all wheels on the
tow truck.
For vehicles equipped with leveling control*:
If the vehicle is equipped with pneumatic suspen-
sion, this feature must be turned off before the
vehicle is lifted onto a tow truck. Turning off the
function in the center display.
1. Tap Settings in the Top view.
2.

Tap My Car Parking Brake and
Suspension .
3. Select Disable Leveling Control.
The vehicle's location and ground clearance
determine if it can be lifted onto a tow truck. If
the incline of the tow truck is too steep or if the
ground clearance under the vehicle is insufficient,
attempting to pull it up may result in damage. In
this case, the vehicle should only be lifted with
the tow truck's lifting equipment.

482 Activating and deactivating the
compass
An integrated compass in the upper right corner
of the rearview mirror shows the direction the
vehicle is traveling.
Activating and deactivating the
compass
The compass is automatically activated when the
vehicle is started.
To deactivate/activate the compass manually:
– Use a paper clip or similar object to press the
button on the bottom of the mirror.

• Compass (p. 481)
• Calibrating the compass (p. 482) Calibrating the compass
The globe is divided into 15 magnetic zones.
The compass should be calibrated if the vehicle
is driven from one zone to another.
To calibrate the compass:
1.
Stop the vehicle in a large, open area away
from steel constructions and high-voltage
power lines.
2. Start the engine and switch off all electrical equipment (climate system, wipers, etc.) and
make sure all doors are closed.
NOTE Calibration may fail or not even be initiated if
electrical equipment is not turned off.
3. Hold the button on the bottom of the rear-
view mirror pressed for about 3 seconds
(using e.g. a paper clip). The number of the
current magnetic zone is shown. 15

mirror repeatedly until the desired magnetic
zone ( 1–15) appears (see the map of mag-
netic zones).
5. Wait until the display again shows C, or
press and hold the button on the underside
of the rearview mirror for approx. 6 seconds
until
C is displayed.
6.
Drive slowly in a circle at a speed of no more
than 10 km/h (6 mph) until a compass direc-
tion is shown in the display. This indicates
that calibration is complete. Drive in a circle
two more times to fine-tune the calibration.
7. Vehicles with heated windshields*: If C is
shown in the display when the windshield
heating function is activated, perform step 6
above with the heating function on.

• Concert hall - reproduces the acoustics of
Gothenburg's Concert Hall
Active noise suppression*Some vehicles are equipped with an active noise
suppression function that reduces engine noise
in the passenger compartment using the audio
system. Microphones in the ceiling liner detect distracting noise and the audio system sends out
a counteracting sound to help reduce the unwan-
ted noise.

tem via the vehicle's USB port.
Devices with rechargeable batteries can be
charged when they are connected via the USB
port and the ignition is in mode I, II or the engine
is running.
The content on the external source can be read
faster if it only contains data of a compatible for-
mat. Video files can also be played via the USB
port.
Some MP3 players have their own file system
that the vehicle has support for.

NOTE Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.
If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.
The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide,
which is invisible and odorless but very poi-
sonous. For this reason, always perform the
calibration procedure outdoors or in a work-
shop with exhaust gas evacuation equipment.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific
dimensions. The tire dimensions vary depending
on engine type. When driving with snow tires, the
correct type of tires must be mounted on all four
wheels.
NOTE Contact a Volvo dealer for advice on the best
choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow
tires, mark the tires according to which side they
were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving
500–1000 km (300–600 miles) slowly and gen-
tly to help the studs settle properly in the tires.
This gives the tire, and especially the studs, a
longer service life.
NOTE
Regulations regarding the use of studded
tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tempera-
tures place considerably higher demands on tires
than summer conditions. Volvo therefore recom-
mends not driving on snow tires that have a tread
depth of less than 4 mm (0.15 inch).

Using snow chains and/or snow tires can help
improve traction in winter driving conditions.
WARNING Use Volvo genuine snow chains or equivalent
snow chains that are suitable for the vehicle
model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom-
mends contacting an authorized Volvo work-
shop. Use of the wrong snow chains could
cause serious damage to the vehicle and
result in an accident.
