pg. 56 Remote keyless entry system
Remote keyless entry system
Your car is equipped with a remote control transmitter. This transmitter uses a radio frequency which will allow
"keyless" entry into the passenger compartment or the trunk. You will be supplied with two coded key ring
transmitters, which will enable you to lock/unlock all doors and the trunk from a distance of 10-15 feet (3-5 meters).
On vehicles equipped with an alarm, the alarm will also be activated/deactivated by this system.
The car can also be locked/unlocked with the key.
As an extra security precaution in certain situations (valet parking, etc.), Volvo recommends that the transmitter not be
included when the keys are given to anyone. The service key can be used instead. If one of the transmitters is
misplaced, contact the nearest authorized Volvo retailer for assistance.

Break-in Period
A new car should be broken in. Refrain from utilizing your car's full driving potential e.g., full-throttle acceleration,
during the first 1,200 miles (2000 km) including the "kickdown" function (automatic transmission).
NOTE ENGINE OIL:
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearingin to each other. From the time the engine is new until the
first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
ProCarManuals.com

important to check the oil every time you refuel your car during this period. See page 111.
Fuel requirements
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).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
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.
Gasoline containing alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as
Ethyl alcohol, or "Gasohol".
Ethers — MTBE: Fuels containing up to 15% MTBE may be used.
pg. 63 Refueling
ProCarManuals.com

Refueling
The fuel tank is designed to hold approximately 21.1 US gal. (80 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 tank cover
The fuel tank cover, located on the right rear fender, is connected to your car's central locking system. The driver's
door must be unlocked before the fuel tank cover can be opened.
Be sure the fuel tank cover is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather conditions.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system (ORVR). Please refer to page
105 for additional information.
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. 64 Starting the engine
ProCarManuals.com

· Dirty engine oil and clogged oil filter
· Dragging brakes
· Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE: (D)rive should be used as often as possible to help improve fuel economy.

Checking and correcting tire pressure
· Check the tire pressure when refuelling.
· The tire pressure should be corrected only when the tires are cold.
· With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label located on the inside of the fuel tankcover. This label lists both tire and vehicle design limits.
Do not load your car beyond the load limits indicated.
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/80 R17.
Recommended tire pressure (see decal on fuel tank cover) 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.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).
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.
NOTE: Certain models may be equipped with a full-size spare wheel.
pg. 83 Wheels and tires
Uniform tire quality grading
All passenger car tires must conform to Federal Safety Requirements in addition to these grades
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,
service practices and differences in road characteristics and climate.
