NOTE
Do not break the seal of the bottle before
use. The seal is broken automatically when
the bottle is screwed into place.
WARNING Please keep the following points in mind
when using the tire sealing system:
The sealing compound bottle (no. 8 in the
illustration) contains 1) rubber latex, natu-
ral and 2) ethanediol. These substances
are harmful if swallowed.
The contents of this bottle may cause
allergic skin reactions or otherwise be
potentially harmful to the respiratory tract,
the skin, the central nervous system, and
the eyes.
Precautions:
Keep out of reach of children.
Do not ingest the contents.
Avoid prolonged or repeated contact with
the skin. Remove any clothing that has
come into contact with sealant.
Wash thoroughly after handling.
First aid:
Skin: Wash affected areas of the skin
with soap and water. Get medical atten-
tion if symptoms occur.
Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the upper
and lower eyelids. Get medical attention if
symptoms occur.
Inhalation: Move the exposed person to
fresh air. If irritation persists, get medical
attention.
Ingestion: Do NOT induce vomiting
unless directed to do so by medical per-
sonnel. Get medical attention.
Disposal: Dispose of this material and its
container at a hazardous or special waste
collection point.
WARNING
Do not remove the bottle while the tire
sealing system is being used.
Do not remove the hose while the tire
sealing system is being used.
1.

Turn on the vehicle's hazard warning flashers
if the tire sealing system is to be used in an
area with traffic.
If the puncture was caused by a nail or simi-
lar object, do not remove it. It will help seal
the hole.
2. Peel off the speed limit sticker from the side of the compressor. Affix the decal to a clearly
visible location on the windshield to remind
the driver not to exceed this speed limit. Do
not drive faster than 80 km/h (50 mph) while
using a tire that has been temporarily
repaired with the tire sealing system.

3.
Make sure the switch is in the 0 (Off) posi-
tion and take out the electric cable and the
hose.
4.

Unscrew the orange cover on the compres-
sor and unscrew the cap on the sealing com-
pound bottle.
5. Screw the bottle onto the bottle holder as far as possible.
The bottle and the bottle holder are equip-
ped with catches to help prevent the sealing
compound from leaking. Once the bottle is
screwed into place into the bottle holder, it
cannot be unscrewed. The bottle can only be
removed by a workshop. Volvo recommends
an authorized Volvo workshop.
WARNING Do not unscrew the bottle. It is equipped with
a catch to prevent leakage.
6.

Unscrew the tire's valve cap and screw the
hose's valve connector as far as possible
onto the valve.
Be sure the air release valve on the com-
pressor's hose is completely closed. 7. Connect the electrical cable to the nearest
12 V outlet and start the vehicle.
NOTE Make sure that none of the vehicle's other
12 V sockets are used while the compressor
is running.
WARNING
Never leave children unattended in the vehicle
while the engine is running.
WARNING
Inhaling exhaust fumes could lead to serious
injury. Never leave the engine running in an
enclosed space or a space without sufficient
ventilation.
8.

Start the compressor by moving the switch to
the I (On) position.
WARNING Never stand next to a tire being inflated with
the compressor. If cracks, bulges, etc. form on
the tire, switch off the compressor immedi-
ately. The vehicle should not be driven. Call
roadside assistance to have the vehicle towed
to a workshop for inspection/replacement of
the tire. Volvo recommends an authorized
workshop.
NOTE
When the compressor first starts, air pressure
may temporarily increase up to 6 bar (88 psi)
but should decrease again after approxi-
mately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor
should never be used for more than
10 minutes at a time.

10. Switch off the compressor and check the
inflation pressure using the air pressure
gauge. The inflation pressure should be
between 1.8 bar (22 psi) and 3.5 bar
(51 psi). If the inflation pressure is too high,
use the air release valve to release air.
WARNING If pressure falls below 1.8 bar (22 psi), the
hole in the tire may be too large. The vehicle
should not be driven. Call roadside assistance
to have the vehicle towed to a workshop for
inspection/replacement of the tire. Volvo rec-
ommends an authorized workshop.
11.

Switch off the compressor and remove the
electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
NOTE
After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove. 13. Put the protective hose cover onto the hose
to help prevent leakage of any residual seal-
ing compound. Return the equipment to the
cargo compartment.
14.

Immediately drive the vehicle at least 3 km
(2 miles) at a maximum speed of 80 km/h
(50 mph) to allow the sealing compound to
seal the tire, and then recheck the inflation
pressure.
NOTE During the tire's first revolution, some sealing
compound may spray out of the puncture
hole.
WARNING
Before driving away, make sure that no one is
near the vehicle who could be sprayed with
sealing compound. Make sure no one is
within 2 meters(7 feet) of the vehicle.
15. Rechecking the inflation pressure
Connect the hose to the tire's valve and
screw the hose connector onto the valve as
far as possible. The compressor must be
switched off. 16.

Check the inflation pressure on the air pres-
sure gauge.
If the pressure is under 1.3 bar (19 psi),
the tire is not sufficiently sealed. The vehi-
cle should not be driven. Call roadside
assistance to have the vehicle towed.
If the inflation pressure is higher than
1.3 bar (19 psi), the tire must be inflated
to the inflation pressure specified on the
tire pressure decal on the driver's side
door pillar (1 bar = 100 kPa = 14.5 psi). If
the inflation pressure is too high, use the
air release valve to release air.
NOTE Replace the sealing compound bottle and
hose after use. Volvo recommends having
these replaced by an authorized Volvo work-
shop.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest author-
ized Volvo workshop to have the tire replaced/
repaired. Inform the workshop that the tire con-
tains sealing compound.

Using the tire sealing system (p. 583)
Tire sealing system (p. 582) Determining the vehicle's permitted
weight
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Weight designationsBefore 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 Vehi-
cle Safety Standards (FMVSS/CMVSS) label, and
the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of
fuel and all standard equipment. It does not
include passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including
cargo and optional equipment. When towing, tow-
bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car-
ried by a single axle (front or rear). These num-
bers 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 + passengers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed
XXX kg or XXX lbs." on your vehicle's plac-
ard.
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 kg or XXX lbs.
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. pas-
sengers in your vehicle, the amount of availa-
ble cargo and luggage load 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 manual to determine
how this reduces the available cargo and lug-
gage load capacity of your vehicle.

WHEELS AND TIRES
589
WARNING
Exceeding the permissible axle weight,
gross vehicle weight, or any other weight
rating limits can cause tire overheating
resulting in permanent deformation 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 vehicle's GVW
rating. Use only tires with the correct load
carrying capacity. Consult your Volvo
retailer for information.
