CAUTION•
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
• Trailer hitches attaching to the vehicle
rear axle must not be used.
• Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
• When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or 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 are
factors that significantly increase a vehicle's
fuel consumption.
Trailer weights
WARNING Please adhere to the recommendations provi-
ded for trailer weight. If the recommendations
are not followed, the vehicle and trailer may
be difficult to control during evasive maneu-
vers and braking.
NOTE
The specified maximum trailer weights are
those permitted by Volvo. National vehicle
regulations may set additional restrictions on
trailer weight and speed. The trailer hitches
may be certified for higher towing weights
than 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 of
load (up to the maximum permitted weight).
When the vehicle is stationary, the rear end of the
vehicle 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 of
the engine and drive system is detected, a warn-
ing symbol will illuminate in the instrument panel
along with a message.The automatic transmission selects the optimal
gear 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.

STARTING AND DRIVING
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.

WHEELS AND TIRES
550Tires
The function of the tires is to carry loads, provide
traction on road surfaces, reduce vibrations and
protect the wheels from wear. The tires significantly influence the vehicle's driv-
ing characteristics. The type, dimensions, tire
pressure and speed rating have a considerable
impact on how the vehicle performs.
Your vehicle is equipped with tires according to
the vehicle's tire information placard on the B-pil-
lar (the structural member at the side of the vehi-
cle, at the rear of the driver's door opening).
WARNING A damaged tire could cause the driver to lose
control of the vehicle.
CAUTION Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration for
hydroplaning resistance. They may be more
susceptible to road hazard damage and,
depending on driving conditions, may achieve
a tread life of less than 30,000 km (20,000
miles). Even if this vehicle is equipped with
Volvo's advanced AWD or stability system,
these tires are not designed for winter driving,
and should be replaced with winter tires when
weather conditions dictate.
The tires have good road holding characteristics
and offer good handling on dry and wet surfaces.
It should be noted however that the tires have
been developed to give these features on snow/
ice-free surfaces.
Most models are equipped with "all-season" tires,
which provide a somewhat higher degree of road-
holding on slippery road surfaces than tires with-
out the "all-season" rating. However, for optimal
roadholding on icy or snow-covered roads, we
recommend snow tires on all four wheels.
When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on allfour wheels. Otherwise there is a risk of altering
the vehicle's roadholding and handling characte-
ristics.
Recommended tiresOn delivery, the car is equipped with Volvo origi-
nal tires that have the VOL
1
marking on the side
of the tires. These tires have been designed spe-
cifically for your vehicle. It is therefore important
when replacing tires that the new tires have this
same marking to help maintain the vehicle's driv-
ing characteristics, comfort and fuel consumption.
New tires Tires are perishable goods. After a few years,
they will begin to harden and their friction proper-
ties will gradually deteriorate. Always replace tires
with the freshest tires possible. This is particularly
important for snow tires. A series of numbers is
1
This may vary for certain tire dimensions.

WARNING •
The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unapproved
wheel/tire size combinations can nega-
tively affect your vehicle's stability and
handling.

Tires with tread designed to roll in only one
direction are marked with an arrow on the side-
wall. The arrow shows the tire's direction of rotation.
• The tire should maintain the same direction
of rotation throughout its service life.
• Tires should only be moved between the
front and back, never from right to left or vice
versa.
• Incorrectly mounted tires impair the vehicle's
braking properties and ability to force aside
rain, snow and slush.
• The tires with the most tread should always
be mounted on the rear wheels to help
reduce the risk of skidding.
NOTE Use tires of the same type, dimensions and
make (manufacturer) on each axle.

Tread wear indicator
The tread wear indicator shows the status of the
tire's tread. The tread wear indicator is a narrow elevated
strip running across the tire's longitudinal tread
grooves. The letters TWI (Tread Wear Indicator)
are visible on the side of the tire. When approxi-
mately 1.6 mm (1/16 inch) is left on the tread,
the tread will be at the same height as the tread
wear indicator. Replace the tire as soon as possi-
ble. Tires with low tread offer very poor traction in
rain or snow.

Tires (p. 550) Tire terminology
The following is a glossary of tire-related terms.
The tire suppliers may have additional markings,
notes or warnings such as standard load, radial
tubeless, etc.
• Tire information placard: A placard show-
ing the OE (Original Equipment) tire sizes,
recommended inflation pressure, and the
maximum weight the vehicle can carry.
• Tire Identification Number (TIN): A number
on the sidewall of each tire providing infor-
mation about the tire brand and manufactur-
ing plant, tire size and date of manufacture.
• Inflation pressure: A measure of the
amount of air in a tire.
• Standard load: A class of P-metric or Metric
tires designed to carry a maximum load at 35
psi [37 psi (2.5 bar) for Metric tires]. Increas-
ing the inflation pressure beyond this pres-
sure will not increase the tires load carrying
capability.
• Extra load: A class of P-metric or Metric
tires designed to carry a heavier maximum
load at 41 psi [43 psi (2.9 bar) for Metric
tires]. Increasing the inflation pressure
beyond this pressure will not increase the
tire's load carrying capability.
• kPa: Kilopascal, a metric unit of air pressure.
• PSI: Pounds per square inch, a standard unit
of air pressure. •
B-pillar: The structural member at the side
of the vehicle behind the front door.
• Bead area of the tire: Area of the tire next
to the rim.
• Sidewall of the tire: Area between the bead
area and the tread.
• Tread area of the tire: Area of the perime-
ter of the tire that contacts the road when
mounted on the vehicle.
• Rim: The metal support (wheel) for a tire or a
tire and tube assembly upon which the tire
beads are seated.
• Maximum load rating: a figure indicating
the maximum load in pounds and kilograms
that can be carried by the tire. This rating is
established by the tire manufacturer.
• Maximum permissible inflation pressure:
the greatest amount of air pressure that
should ever be put in the tire. This limit is set
by the tire manufacturer.
• Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that are
mounted on a vehicle at the factory. This
information can be found on the tire inflation
placard(s) located on the driver's side B-pillar
and in the tire inflation table in this chapter.
• Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This tem-

M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number
(TIN): This begins with the letters "DOT" and
indicates that the tire meets all federal
standards. The next two numbers are the
factory code where the tire was manufac-
tured, the next two are the tire size code and
the last four numbers represent the week
and year the tire was made. For example,
0717 means that the tire was manufactured
during week 7 of 2017. The numbers in
between are marketing codes used at the
manufacturer's discretion. This information
helps a tire manufacturer identify a tire for
safety recall purposes.
9. Tire Ply Composition and Material Used:
Indicates the number of plies indicates or the
number of layers of rubber-coated fabric in
the tire tread and sidewall. Tire manufactur-
ers also must indicate the ply materials in the
tire and the sidewall, which include steel,
nylon, polyester, and others.
10. Maximum Load: Indicates the maximum
load in pounds and kilograms that can be
carried by the tire. Refer to the vehicle's tire information placard located on the B-Pillar
for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature
grades.
12. Maximum permissible inflation pressure:
the greatest amount of air pressure that
should ever be put in the tire. This limit is set
by the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-
mum speed for which the tire has been certified
and should be at least equivalent to the vehicle's
top speed.
Winter tires, with or without studs, are exceptions
and may use a lower SS. When winter tires are
installed, the vehicle may not be driven faster
than the tires' SS.
The vehicle's speed should always be determined
by the posted speed limit and traffic and road
conditions, not the tire's SS.
The following table indicates the maximum per-
missible speed for each SS. M 130 km/h (81 mph)
