Tire sealing system
Introduction
Certain models are equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface
and reinflate a flat tire, or to adjust a tire's inflation pressure.
The system consists of an air compressor, a container for the sealing compound, wiring to connect the system to the
vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the tire's inflation
valve.
The 12-volt sockets are located in the front tunnel console and in the trunk (option). See pages 66
and 108.
Accessing the tire sealing system
The tire sealing system is stowed in the compartment in the rear side of the ski hatch in the center of the rear seat
backrest. See page 109
for information on opening this hatch
NOTE
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km). Have the tire replaced as soon as possible.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Tire sealing system
Tire sealing system-temporarily repairing a flat tire
ProCarManuals.com

Temporarily repairing a flat tire is done in two stages:
Stage 1: The hole is sealed by pumping sealing compound into the tire. The car is then driven a short distance to
distribute the sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealing system.
NOTE
Stage 2: The tire's inflation pressure is checked and adjusted if necessary.
WARNING
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system away from children.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Stage 1: Sealing the hole
1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it to the steering wheel hub where it will be clearly visible to the driver.
3. Ensure that the on/off switch is in position 0 (the 0 side of the switch should be pressed down).
4. Put on the gloves included in the tire sealing system.
5. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle is screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealing compound leakage. Once in
place, the bottle cannot be unscrewed. This must be done by a Volvo retailer.
7. Remove the valve cap from the tire's inflation valve and screw the tire sealing system's hose connector onto the
valve as tightly as possible by hand.
8. Connect the electrical wire to the nearest 12-volt socket in the vehicle.

9. 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 outdoors, before using the system.
10. 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 approximately 88 psi (6 bar) while the
sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately 30
seconds.
11. 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.
12. Switch off the compressor and disconnect the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
14. Immediately drive the vehicle for approximately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to
distribute the sealing compound in the tire.
NOTE
Safely stow the tire sealing system in a convenient place as it will soon be used again to check the tire's inflation
pressure.
After use, the empty bottle of sealing compound cannot be removed from the bottle holder. Consult a Volvo
retailer to have the bottle removed and properly disposed of.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the
ProCarManuals.com

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 workshop or
Volvo retailer.
Stage 2: Checking inflation pressure
1. Connect the tire sealing system as described in stage 1.
2. Refer to the tables on pages 172 and 173
for the correct tire inflation pressure. If the tire needs to be

Tire Pressure Monitoring System (TPMS)
Introduction
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
ProCarManuals.com

the vehicle is moving at a speed of approximately 20 mph (30 km/h) or faster, these sensors transmit inflation pressure
data to a receiver located in the vehicle.
NOTE
USA - FCC ID: KR5S122780002
This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pressure warning light (
) (also referred to as a
telltale) in the instrument panel, and will display a message in the text window. The wording of this message is
determined by the degree of inflation pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS
SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that
illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

Tire Pressure Monitoring System (TPMS)
NOTE
ProCarManuals.com

TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables beginning on page 172 or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is underinflated. Be sure to check all four tires.
A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes
in temperature. Always check tire pressure regularly.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables beginning on page 172
.
3. In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or
faster. This will erase the warning text and the warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear. If the message is still
displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
NOTE
If you change to tires with a different recommended inflation pressure, the TPMS system must be recalibrated to
these tires. This must be done by a trained and qualified Volvo service technician.
If a tire is changed, or if the TPMS sensor is moved to another wheel, the sensor's seal, nut, and valve core should
be replaced.
When installing TPMS sensors, the vehicle must be parked for at least 15 minutes with the ignition off. if the
vehicle is driven within 15 minutes, a TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.
