CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
• In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.

Driver responsibilityThe driver should keep in mind that PAP is a
parking aid ‒ not an infallible fully automatic sys-
tem. The driver must always be prepared to take
control and cancel a parking sequence if neces-
sary.
There are a number of things to keep in mind
when parking, including:
• The driver is always responsible for determin-
ing if the space suggested by PAP is suita-
ble for parking.
• Do not use PAP when using snow chains or
a temporary spare tire.
• Do not use PAP if there are any objects pro-
truding from the vehicle.
• Heavy rain or snowfall may inhibit PAP's abil-
ity to accurately measure a parking space.
• While searching and measuring the parking
space, PAP may be unable to detect objects
located far into the space.
• PAP may not suggest parking spaces on
narrow streets if it does not detect sufficient
space for maneuvering the vehicle. •
Use approved tires 128
inflated to the correct
tire pressure because this affects PAP's abil-
ity to provide parking assistance.
• PAP's function is based on the way the vehi-
cles are parked behind and in front of your
parking space. If they are, for example,
parked too close to the curb, there is a risk
that your vehicle's tires or wheel rims could
be damaged by the curb during the parking
procedure.
• Perpendicular parking spaces may not be
detected or may be suggested unnecessarily
if a parked vehicle is sticking out more than
other parked vehicles.
• PAP is intended to provide parking assis-
tance on straight streets, not sections of
street with sharp curves or bends. Always
make sure that your vehicle is parallel to rel-
evant parking spaces when PAP is measur-
ing the parking space.
CAUTION Switching to another approved wheel and/or
tire dimension could change the tire circum-
ference, which would then require the PAP
system to be updated. Consult a workshop –
an authorized Volvo workshop is recom-
mended.

STARTING AND DRIVING

•
Speed limiter (p. 278)
• Tire sealing system (p. 572) Winter driving
It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.
Before the cold season arrives:• Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.
• Keep the fuel tank well filled to prevent con-
densation from forming.
• Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.
CAUTION Low-viscosity oil should not be used with hard
driving or in hot weather.
•
Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.
• Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.
Slippery driving conditionsFor optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.
NOTE Certain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.
Practice driving on slippery surfaces under con-
trolled conditions to learn how the vehicle reacts.

WARNING •
The vehicle must never be driven with
more than one "Temporary spare" tire
mounted.
• Driving with a spare wheel may alter the
driving characteristics of the vehicle.
Replace the spare wheel with a normal
wheel as soon as possible.
• The spare wheel is smaller than the nor-
mal wheel, which affects the vehicle's
ground clearance. Watch for high curbs
and do not wash the vehicle in an auto-
matic car wash when a spare wheel is
mounted.
• Follow the manufacturer's recommended
tire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive on
the rear axle can be disconnected.
• If the spare wheel is mounted on the
front axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION The vehicle must not be driven with wheels of
different dimensions or with a spare tire other
than the one that came with the vehicle. The
use of different size wheels can seriously
damage your vehicle's transmission.

• Recommended tire pressure (p. 559) Accessing the spare wheel
Follow these instructions regarding handling the
spare wheel. The spare wheel is stored in a bag and should be
secured with two straps onto the floor of the
trunk/cargo compartment when the vehicle is
being driven
12
. The straps should be strapped
down crosswise over the wheel, attached to the
load anchoring eyelets and pulled taut.
Wheel changing tools are located under the
cargo compartment floor.

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.

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.

Winter driving (p. 461) Tire sealing system
13
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 14
do not
have the tire sealing system.
The tire sealing system consists of a compressor
and a bottle containing sealing compound. The
sealing functions as a temporary repair.
NOTE The sealing compound effectively seals tires
with punctures in the tread but may not be
able to fully seal tires with punctures in the
sidewall. Do not use the tire sealing system
on tires with large tears, cracks or similar
damage.
NOTE
The compressor is intended for temporary tire
sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block
under the floor of the cargo compartment.
