Driving with a trailer (p. 483) Towing 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. The vehicle must be lifted onto a
tow truck and transported with all four wheels on
the bed or lifting platform of the truck (no wheels
may touch the road).
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.

Recovery
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.
WARNING No person or object should be behind the tow
truck when the vehicle is lifted onto the bed
of the truck.

Bluetooth-enabled external devices such as cel-
lular phones and tablets.
In order for the media player to be able to wire-
lessly play audio files from an external device, the
device must be connected to the vehicle via
Bluetooth.

faster if it only contains data of a compatible for-
mat. Video files can also be played via the USB

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.

The backrest in the third row of seats* must be folded down.

CAUTION
Snow chains can be used on the vehicle, with
the following restrictions:
Volvo recommends not using snow
chains on wheel dimensions larger than
19 inches.
Always follow the manufacturer's installa-
tion instructions carefully. Install chains
as tightly as possible and retighten peri-
odically.
Only put snow chains on the front wheels
(also applies to all-wheel drive vehicles).
If accessory, aftermarket or "custom"
tires and wheels with different dimen-
sions than the original tires and wheels
are used, snow chains in some cases
may NOT be used. Sufficient distance
between the chains and brakes, suspen-
sion and body components must be
maintained.
Check local regulations regarding the use
of snow chains before installing.
Never exceed the snow chain manufac-
turer's specified maximum speed limit.
Under no circumstances should you
exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turns when
driving with snow chains.
Avoid driving on surfaces without snow as
this wears out both the snow chains and
the tires.
The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Some types of strap-on chains affect
brake components and therefore must
NOT be used. Consult a Volvo retailer for more information
about snow chains.

The temporary tire sealing system can be used
to seal a puncture in a tire or to check and
adjust the pressure in the tire.
Models equipped with a spare wheel 18
do not
have the tire sealing system.
WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/
passenger-vehicle.
The tire sealing system consists of a compressor
and a bottle containing sealing compound. The
sealing functions as a temporary repair.
