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 122 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.

Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to
help stabilize a vehicle that is towing a trailer
when the vehicle and trailer have begun to
sway and is part of the Dynamic Stability and
Traction Control system (DSTC). See page
148 for information on DSTC.
FunctionA vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at
high speeds but, for example, if the trailer is
overloaded or if the load is unevenly distributed
in the trailer, there is risk of swaying at speeds

06 During your trip

between approximately 45-55 mph (70-90 km/
h).
Swaying may be caused by factors such as:
•The vehicle and trailer are hit by a sudden,
strong crosswind
•The vehicle and trailer are traveling on an
uneven road surface or drive over a bump
•Sudden movements of the steering wheel
Facts about TSA
•TSA intervenes at speeds above approxi-
mately 40 mph (60 km/h)
•The DSTC symbol () in the instru-
ment panel will flash when TSA is working
•If the driver switches off the DSTC sys-
tem's Spin Control function, TSA will also
be switched off (but will be on again the
next time the engine is started)
•TSA may not intervene when the vehicle
and trailer begin to sway if the driver tries
to compensate for the swaying motion by
moving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi-
cult to stop, which makes it difficult to control
the vehicle and trailer.
The TSA system continuously monitors the
vehicle's movements, particularly lateralmovement. If the system detects a tendency to
sway, the brakes are applied individually on the
front wheels, which has a stabilizing effect on
the vehicle and trailer. This is often enough to
enable the driver to regain control of the vehi-
cle.
If this is not adequate to stop the swaying
motion, the brakes are applied to all of the
wheels on the vehicle and on the trailer if it is
equipped with brakes, and engine power is
temporarily reduced. As the swaying motion
begins to decrease and the vehicle-trailer have
once again become stable, TSA will no stop
regulating the brakes/engine power and the
driver regains control of the vehicle.

283 Towing eyelet
G017464
Location of the towing eyelet
Attaching the towing eyelet
Attaching the towing eyeletThe towing eyelet is located under the floor
of the cargo area, 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).
There are two different types of covers over
the openings for the towing eyelet and they
have to be opened differently.
•If the cover has a notch, insert a coin,
etc., into the notch and pry open the
edge of the cover. Open the cover com-
pletely and remove it.
•If the cover has a mark along one edge
or in a corner, press the mark while pry-
ing out the opposite side/corner using a
coin, etc. Open the cover and remove it.
Screw the towing eyelet in place, first by hand
and then using the tire iron until it is securely in
place.
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.
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.
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.
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 being
towed
•Attach jumper cables (see page 113) to
provide current for releasing the electric
parking brake and to move the gear selec-
tor from the P position to N.
•Be sure that the steering wheel lock is
released (see page 90).
•While the vehicle is being towed, set the
ignition in mode II if the battery is not

drained so that the headlights/taillights can
be switched on. See page 82 for informa-
tion on the ignition modes.
•Maximum speed: 50 mph (80 km/h). Do not
exceed the maximum allowable towing
speed.
•Maximum distance with front wheels on
ground: 50 miles (80 km).
•While the vehicle is being towed, try to
keep the tow rope taut at all times.
•The vehicle should only be towed in the
forward direction.
CAUTION
Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds above 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle's battery is dead, do not
attempt to start the vehicle by pushing
or pulling it as this will damage the
three-way catalytic converter(s). The
engine must be jump started using an
auxiliary battery (see page 113).
•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 or to secure the vehicle on the flat
bed. Consult the tow truck operator.
Towing vehicles with front wheel drive/
All Wheel Drive
Volvo recommends the use of flat bed equip-
ment.
•If wheel lift equipment must be used,
please use extreme caution to help avoid
damage to the vehicle. In this case, the
vehicle should be towed with the rear
wheels on the ground if at all possible.
•If it is absolutely necessary to tow the vehi-
cle with the front wheels on the ground,please refer to the towing information on
page 283.
CAUTION
•Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
•It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage to the rear axle may
result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.

7. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
8. Start the vehicle’s engine.
WARNING
The vehicle´s engine should be running
when the tire sealing system is used to avoid
battery drain. Therefore, be sure the vehicle
is parked in a well ventilated place, or out-
doors, before using the system.
9. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•Never stand next to the tire being inflated
when the compressor is in operation.
•If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.
•If there is visible damage to the sidewall
or the rim, the tire cannot be repaired.
The vehicle should not be driven if this
occurs. Contact a towing service or
Volvo On Call Roadside Assistance if
applicable.
NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
10. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi
(1.8 bar) after approximately seven minutes,
turn off the compressor. In this case, the
hole is too large to be sealed and the vehicle
should not be driven.
11. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.12. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
13. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged tire's inflation pressure.
NOTE
•Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.
•The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.

WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure table in this
chapter for the correct inflation pressure. If
the tire needs to be inflated, start the tire
sealing system’s compressor. If neces-
sary, release air from the tire by turning the
air release knob counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.
Replacing the sealing compound
container
The sealing compound container must be
replaced if:
•the tire sealing system has been used to
repair a tire
•the container’s expiration date has passed
(see the date on decal).
NOTE
•After use, the sealing compound bottle,
the hose, and certain other system
components must be replaced. Please
consult your Volvo retailer for replace-
ment parts.
•If the sealing compound bottle’s expi-
ration date has passed, please take it to
a Volvo retailer or a recycling station
that can properly dispose of harmful
substances.
Inflating tires
The tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
6. Start the vehicle’s engine.
WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to

317 Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.
Each time the car is refueled:
•Check the engine oil level.
•Clean the windshield, windshield wipers,
headlights, and taillights.
Monthly:
•Check cold tire pressure in all tires. Inspect
the tires for wear.
•Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
•Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•Wipe driver information displays with a soft
cloth.
•Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult your Volvo
retailer for additional information.
As needed:Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup
of dirt, and corrosion that can be caused by salt
residues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other pla-
ces where they may collect.
NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.They are specially reinforced to bear the weight
of the vehicle. A garage jack can also be placed
under the front of the engine support frame.
Take care not to damage the splash guard
under the engine. Ensure that the jack is posi-
tioned so that the vehicle cannot slide off it.
Always use axle stands or similar structures.
If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type of

08 Maintenance and specifications

inspection has replaced the tailpipe emission
test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspec-
tion for any of the following reasons.
•If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
•If your vehicle's Check Engine light was lit,
but went out without any action on your
part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending
on the inspection practices in your area.
•If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
•If your Check Engine (MIL) light is lit – or
was lit but went out without service, have
your vehicle diagnosed and, if necessary,
serviced by a qualified Volvo technician.
•If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a
period of driving is necessary to bring the
OBD II system to "ready" for inspection. A
half-hour trip of mixed stop-and-go/high-way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.
•Maintain your vehicle in accordance with
your vehicle's maintenance schedule.
