position II) and the brake pedal must be depressed.
Select the desired gear. On models with an automatic transmission, the gear engages after a very slight delay which
is especially noticeable when selecting R.
NOTE:
Immobilizer : If two of the keys to your vehicle are close together, e.g., on the same key ring when you try to start
the vehicle, this could cause interference in the immobilizer system and result in the vehicle not starting. If this should
occur, remove one of the keys from the key ring before trying to start the vehicle again.
Keylock: Your vehicle is equipped with a keylock system. When the engine is switched off, the gear selector must
be in the (P)ark position before the key can be removed from the ignition switch.
When starting in cold weather, the automatic transmission may shift up at slightly higher engine speeds than normal
until the automatic transmission fluid reaches normal operating temperature.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
WARNING!
Volvo's floor mats are specially manufactured 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.

Starting the engine
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 transmission wear. Selecting P or N when idling at a standstill for prolonged periods of time will help
prevent overheating of the automatic transmission fluid.
WARNING!
Always place the gear selector in Park (1st gear or reverse on models with a manual transmission) and apply the
parking brake before leaving the vehicle. 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 monoxide, which is invisible and odorless but very poisonous.

Never attempt to push- or tow-start a vehicle with a dead battery. This would inject unburned fuel into the three-
way catalytic converter(s), causing overheating, backfiring, and damage. See page 119 for instructions on jump
starting the vehicle.
Having the car towed
Volvo recommends the use of flat bed equipment for towing vehicles with front wheel drive. 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 vehicle with the front wheels on the ground, please refer to the towing
information on the previous page.
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use slingtype equipment at the rear or apply lifting 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.
WARNING!
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.

Jump starting
Follow these instructions to jump start your vehicle's dead battery or to jump start another vehicle's dead battery using
your vehicle. If the 12-volt auxiliary battery to be used is in another vehicle, check that the vehicles are not touching to
prevent premature completion of a circuit. Be sure to follow jump starting instructions provided for the other vehicle.
To jump start your vehicle:
Switch off the ignition.
First connect the auxiliary battery positive (+) terminal (1) to the positive (+) terminal in your vehicle's battery (2),
marked with a "+" sign.
Connect the auxiliary battery's negative (-) terminal (3) to the ground point in your vehicle's engine compartment
near the driver's side spring strut (4).
Start the engine in the assisting vehicle, then start the engine in the vehicle with dead battery.

Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
NOTE:
The location of the various labels in your vehicle can be found on page 188.
A table listing important weight limits for your vehicle can be found on page 189.
Steps for Determining Correct Load Limit
(1) Locate the statement ''the combined weight of occupants and cargo should never exceed XXX pounds'' on your
vehicle's placard.
(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 kilograms or XXX pounds.
(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. passengers in your vehicle, the amount of available cargo and
luggage load capacity is 650 lbs. (1400-750 (5 x 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
1 to determine how this reduces the available cargo and luggage load capacity of your vehicle.
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. Replacement tires with a higher limit than the originals do
not increase the vehicle's GVW rating limitations.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature
A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction

Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
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.
Within seven minutes, inflate the tire to between 22 - 50 psi (1.8 - 3.5 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge (9).
CAUTION!
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.
Disconnect the electrical wire from the 12-volt socket.
Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
Fold down the orange section of the tire sealing system to its original (horizontal) position and press the safety catch
into place.
Safely stow the tire sealing system kit in a convenient place as it will soon be used again to check the tire's inflation
pressure.
Immediately drive the vehicle for approximately 2 miles (3 km) to distribute the sealing compound in the tire.
WARNING!
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the car
in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the
pressure is below 16 psi (1.3 bar), do not continue driving. Have the vehicle towed to a workshop or Volvo retailer.
Stage 2: Checking inflation pressure
Park the car in a safe place.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Start the vehicle's engine.
Check the tire's inflation pressure on the gauge (9).
NOTE: In dark conditions, switching on the tire sealing system's compressor will illuminate the pressure gauge.
Inflate the tire to the correct pressure as indicated in the tire inflation tables on page 116. If the tire needs to be
inflated, start the tire sealing system's compressor. If necessary, release air from the tire by pressing the vent button (8).
Turn off the compressor (press switch 2 to the 0 position) when the correct inflation pressure has been reached.

Three-way catalytic converter
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 conditions, such
as engine overheating or backfiring. 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 conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-
way catalytic converter or exhaust system overheating.
Remember that tampering or unauthorized modifications to the engine, the Engine Control Module, or the vehicle
may be illegal and can cause three-way catalytic converter or exhaust system overheating. This includes:
- Altering fuel injection settings or components.
- Altering emission system components or location or removing components.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for vehicles with three-way catalytic converters.
