163 General information
•Volvo recommends the use of Volvo trailer
hitches that are specially designed for the
vehicle.
Maximum trailer weights recommended by
Volvo are:
•Trailers without brakes: 1,540 lbs
(700 kg).
•Trailers with brakes: 2,000 lbs (900 kg)
Observe the legal requirements of the
state/province in which the vehicles are
registered.
•The maximum recommended hitch
tongue load is 165 lbs (75 kg).
•All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•Increase tire pressure to recommended
full. See the chapter "Wheels and tires."
•When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•Maximum speed when towing a trailer:
50 mph (80 km/h).
•Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watched
when driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•If the automatic transmission begins to
overheat, a message will be displayed in
the information display.
•Avoid overload and other abusive opera-
tion.
•Hauling a trailer affects handling, durabil-
ity, and economy.
•It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•Do not connect the trailer's brake system
directly to the vehicle's brake system.
•More frequent vehicle maintenance is
required.
•Remove the ball and drawbar assembly
when the hitch is not being used.
•Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•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's
rear axle must not be used.
•Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest trained
and qualified Volvo service technician
for correct installation.
•When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

Rear park assist*

172* Option/accessory, for more information, see Introduction.
Audible signals from the park assist
system
The Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
behind the vehicle. If the volume of another
source from the audio system is high, this will
be automatically lowered.
Faults in the system
If the information symbol illumi-
nates and PARK ASSIST
SERVICE REQUIRED is shown
on the information display, this
indicates that the system is not
functioning properly and has been disengaged.
Consult a Volvo retailer or authorized Volvo
service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.
Cleaning the sensors
Park assist sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

07 Wheels and tires
Snow chains, snow tires, studded tires

189 Snow chains
Snow chains can be used on your Volvo with
the following restrictions:
•Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
•Certain size tires may not allow the assem-
bly of snow chains/traction devices.
Consult your Volvo retailer for additional snow
chain information.
CAUTION
•Check local regulations regarding the
use of snow chains before installing.
•Always follow the chain manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.
•Never exceed the chain manufacturer's
specified maximum speed limit. (Under
no circumstances should you exceed
31 mph (50 km/h).
•Avoid bumps, holes or sharp turns
when driving with snow chains.
•The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires
Tires for winter use:
•Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are strongly
advised to fit suitable winter tires to help
retain the highest degree of traction.
•It is important to install winter tires on all
four wheels to help retain traction during
cornering, braking, and accelerating. Fail-ure to do so could reduce traction to an
unsafe level or adversely affect handling.
•Do not mix tires of different design as this
could also negatively affect overall tire road
grip.
•Winter tires wear more quickly on dry roads
in warm weather. They should be removed
when the winter driving season has ended.
•Studded tires should be run-in
300–600 miles (500–1000 km) during
which the car should be driven as smoothly
as possible to give the studs the opportu-
nity to seat properly in the tires. The tires
should have the same rotational direction
throughout their entire lifetime.
NOTE
Please consult state or provincial regula-
tions restricting the use of studded winter
tires before installing such tires.

08 Car care
Washing and cleaning the car
08

207
Keeping the underbody clean is most impor-
tant, especially in the winter. Some automatic
washers do not have facilities for washing the
underbody.
CAUTION
•Before driving into an automatic car
wash, turn off the optional rain sensor to
avoid damaging the windshield wipers.
•Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them
•Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.
WARNING
•When the car is driven immediately after
being washed, apply the brakes several
times in order to remove any moisture
from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or taillights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and Waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
CAUTION
Volvo does not recommend the use of long-
life or durable paint protection coatings,
some of which may claim to prevent pitting,
fading, oxidation, etc. These coatings have
not been tested by Volvo for compatibility
with your vehicle's clear coat. Some of them
may cause the clear coat to soften, crack,
or cloud. Damage caused by application of
paint protection coatings may not be cov-
ered under your vehicle's paint warranty.
Upholstery care
FabricClean with soapy water or a detergent. For
more difficult spots caused by oil, ice cream,
shoe polish, grease, etc., use a clothing/fabric
stain remover. Consult your Volvo retailer.
Interior plastic componentsCleaning interior plastic components should
be done with a cleaning agent specially
designed for this purpose. Consult your Volvo
retailer.
Alcantera™ suede-like materialSuede-like upholstery can be cleaned with a
soft cloth and mild soap solution.
