WARNING
Volvo's floor mats are specially manufac-
tured for your car. They must be firmly
secured in the clips on the floor so that they
cannot slide and become trapped under the
pedals on the driver's side.•
Always place the gear selector in Park
(P) (manual transmission: first or reverse
gear) and apply the parking brake
before leaving the vehicle.and apply the
parking brake before leaving the vehi-
cle. Never leave the vehicle unattended
with the engine running.
•
Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The
exhaust gases contain carbon monox-
ide, which is invisible and odorless but
very poisonous.CAUTION
Automatic transmission: The engine
should be idling when you move the gear
selector. Never accelerate until after you
feel the transmission engage! Accelerating
immediately after selecting a gear will cause
harsh engagement and premature trans-
mission wear. Selecting P or N when idling
at a standstill for prolonged periods of time
will help prevent overheating of the auto-
matic transmission fluid.

06 Starting and drivingTowing a trailer
06160
General information•
Volvo recommends the use of Volvo trailer
hitches that are specially designed for the
vehicle.CAUTION
Models equipped with the B5244S7 engine
(engine code 39 , which is the 6th and
7th digits from the left in your vehicle's VIN
number, see page 262 for the location of
the VIN plate), may not be used to tow trail-
ers or vehicles of any kind. This could cause
damage to the vehicle's emission control
systems.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.

07 Wheels and tiresTire Sealing System
07196
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 tiresThe 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 posi-
tion0 (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
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem.•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation tables for the cor-
rect inflation pressure. If the tire needs to
be inflated, start the tire sealing system’s
compressor (press the on/off switch to
position I). If necessary, release air from the
tire by turning the air release knob coun-
terclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
9. Turn off the compressor (press the on/off
switch to position 0) when the correct infla-
tion pressure has been reached.
10. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
11. Disconnect the electrical wire from the
12-volt socket.

11 SpecificationsThree-way catalytic converter
11274
Three-way catalytic converter –
general information•
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
•
Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•
Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•
Remember that tampering or unauthorized
modifications to the engine, the Electronic
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes:
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
