Automatic reset function
If only the driver's door is unlocked with the remote control, the lock will automatically re-engage (re-lock) and the
alarm will reset after 2 minutes unless the door has been opened.
Temporarily disconnecting the alarm sensor(s)
In certain situations it may be desirable to disconnect the optional alarm sensors, particularly the inclination sensor, if,
for example, you drive your car onto a ferry where the rocking of the boat could trigger the alarm.
To temporarily disconnect the sensor(s) from the alarm system:
With both doors closed, switch off the ignition and remove the key from the ignition switch
Press the locking (left) side of the central locking button on the driver's door for at least 3 seconds
The doors will first lock and then unlock after 3 seconds to confirm that the sensors have been disconnected
The car can then be locked in the usual way to set the alarm.
NOTE: The sensors will automatically be reconnected to the alarm system the next time the ignition is switched on.
LED alarm status signals
The status of the alarm system is indicated by the red LED at the top center of the dash:
LED off - the alarm is not armed (set)
LED flashes once per second - the alarm is armed (set)
LED flashes rapidly before the ignition is switched on - the alarm has been triggered
LED flashes rapidly for 15 seconds after the ignition has been switched on - a fault has been detected in the alarm
system. Contact a Volvo retailer.

Deposit control (detergent) gasoline
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good driveability and
fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service
station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE : Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).

Fuel filler door control on driver's door
Refueling
The fuel tank holds approximately 18 US gal. (68 liters) with sufficient volume left over to accommodate possible
expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat less than the specified
maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning
light comes on.
Fuel filler door
The fuel filler door (on the right rear fender) is locked and must be popped open using the control on the driver's door.
Open fuel filler cap slowly during hot weather conditions
CAUTION:
Do not refuel with the engine running. Turn the ignition off or to position I. If the ignition is on, an incorrect reading
could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted surfaces, which
may not be covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
pg. 63 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
ProCarManuals.com

and the brake pedal must be depressed. See page 101 for instructions on manually releasing the SHIFTLOCK
system.
NOTE: (Automatic transmission only)
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
( P )ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay (automatic transmission) which is especially noticeable
when selecting R.
CAUTION : (Automatic transmission only)
The engine should be idling; never accelerate until after you feel the gear engage! Too-rapid acceleration immediately
after selecting a gear will cause harsh engagement and premature transmission wear.
NOTE : Selecting P or N (automatic transmission) when idling at a standstill for prolonged periods of time will help
prevent overheating of transmission oil.
WARNING!
Always place the gear selector (automatic transmission) in Park and apply the parking brake before leaving the
vehicle. Never leave the car unattended with the engine running.
Always open the 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.
CAUTION: Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast
enough to prevent engine damage.
Do not race the engine just prior to switching off!
* If the key is left in the Drive position (position II) for more than 30 seconds, it must be turned to position 0 and then
turned to the Start position (position III) again in order to start the car. See page 21
for ignition key positions.

tire damage.
Wear indicator
The tires have a so called "wear indicator" in the form of a number of narrow strips running across or parallel to the
tread. When approx. 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire should be
replaced.
Tires with less than 1/16" (1.6 mm) tread have a very poor grip in rain or snow.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
To improve tire economy:
Maintain correct tire pressure.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction
as prior to rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
pg. 81 Wheels and tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
Snow chains may be mounted on tire dimension 195/65R15. Tire dimension 205/55R16 requires a special type of
snow chain. Consult your Volvo retailer.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Snow chains cannot be used on those models fitted with all-
season tires 225/50 R16 or 225/45 R17 or 225/40R18. Sufficient clearances between chains and brakes, suspension
and body components must be maintained.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used.
Consult your Volvo retailer for additional snow chain information.

Clean the contact surfaces on the wheel and hub. Lift the wheel and place it on the hub. Make sure that you align the
wheel with the guide stud on the wheel hub prior to installation. Install the wheel bolts crosswise (see illustration) and
tighten by turning lightly clockwise. Lower the vehicle to the ground and alternately tighten the bolts to 100 ft. lbs.
(130 Nm). Install the wheel cap (where applicable).
CAUTION: Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or
lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the
hub caps.
Correct tightening order for wheel bolts
pg. 88 Spare tire
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/90 R15.
Recommended tire pressure (see decal on fuel filler flap) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one that
came with the car. The use of different size wheels can seriously damage your car's transmission.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).
