NOTE
•When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. Always
follow the trailer manufacturer's recom-
mendations for wheel chocking.
•When starting on a hill, put the gear
selector in D before releasing the park-
ing brake. See also page 117 for more
detailed information about starting off
on a hill while towing a trailer.
•If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
•The drawbar assembly/trailer hitch may
be rated for trailers heavier than the
vehicle is designed to tow. Please
adhere to Volvo's recommended trailer
weights.
•Avoid driving with a trailer on inclines of
more than 15 %.
Trailer cableAn adapter is required if the vehicle's trailer
hitch has a 13-pin connector and the trailer has
7 pins. Use an adapter cable approved by
Volvo. Make sure the cable does not drag on
the ground.

209 Towing eyelet
G021500
G021501
Attaching the towing eyelet
The towing eyelet is located under the floor of
the trunk, with the spare tire. This eyelet must
be screwed into the positions provided on the
right sides of either the front or rear bumper
(see illustration).
CAUTION
If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to pull the vehicle up onto the flat bed.
NOTE
On certain models equipped with a trailer
hitch, the towing eyelet cannot be screwed
into the hole in the rear bumper. The towing
rope should be attached to the trailer hitch
instead. For this reason, the detachable
section of the trailer hitch should be safely
stowed in the vehicle at all times.
Attaching the towing eyeletUse a coin to pry open the lower edge of
the cover.
Screw the towing eyelet in place, first by
hand and then using the tire iron until it is
securely in place.
WARNING
Do not use the towing eyelets to pull the
vehicle up onto a flat bed tow truck.
After the vehicle has been towed, the eyelet
should be removed and returned to its storage
location.

Press the cover for the attachment point
back into position.
WARNING
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but con-
siderably higher pressure will be
required on the brake pedal and greater
steering effort must be exerted.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
Precautions when the vehicle is in tow
•The steering wheel must be unlocked. The
remote key must be in the ignition slot1.
•Attach jumper cables (see page 109) to
provide current for releasing the optional
electric parking brake and to move the gear
selector from the P position.
1On vehicles with the optional keyless drive, the remote key must be in the passenger compartment.

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.
Glossary of tire terminology
The tire suppliers may have additional mark-
ings, notes or warnings such as standard load,
radial tubeless, etc.
•Tire information placard: A placard
showing the OE (Original Equipment) tire
sizes, recommended inflation pressure,
and the maximum weight the vehicle can
carry.
•Tire Identification Number (TIN): A num-
ber on the sidewall of each tire providing
information about the tire brand and man-
ufacturing plant, tire size and date of man-
ufacturer.
•Inflation pressure: A measure of the
amount of air in a tire.
•Standard load: A class of P-metric or Met-
ric tires designed to carry a maximum load
at 35 psi [37 psi (2.5 bar) for Metric tires].
Increasing the inflation pressure beyond
this pressure 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 pres-
sure.
•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 perim-
eter 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 kilo-
grams that can be carried by the tire. This
rating is established by the tire manufac-
turer.
•Maximum permissible inflation
pressure: the greatest amount of air pres-sure 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
inflation pressure is affected by the number
of occupants in the vehicle, the amount of
cargo, and the speed at which the vehicle
will be driven for a prolonged period. This
information can be found on the tire infla-
tion 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-
perature is normally reached after the vehi-
cle has been parked for at least 3 hours.
Vehicle loading
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Before loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a
trailer, from the vehicle's Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard:

Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.
Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer", see
page 207.
Permissible axle weightThe maximum allowable weight that can be
carried by a single axle (front or rear). These
numbers are shown on the Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label. The total load on each axle must
never exceed its maximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-
gers.
NOTE
•The location of the various labels in your
vehicle can be found on page 271.
•A table listing important weight limits for
your vehicle can be found on page
274.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle's placard.
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or
XXX pounds.
4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the "XXX" amount
equals 1400 lbs. and there will be five
150 lb. passengers in your vehicle, the
amount of available cargo and luggageload capacity is 650 lbs. (1400 – 750
(5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual1 to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
WARNING
•Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.
