Trip computer controls and functions
The four* trip computer functions can be accessed by twisting control B
one step at a time in either direction. Twisting the control a fifth time**
returns you to the original function.The trip computer can be reset (current data will be erased from system
memory) by pressing RESET (button C).
1. Driving distance on current fuel reserve
This function shows the approximate distance that can be driven on the
fuel remaining in the tank. This calculation is based on average fuel
consumption during the last 12 miles (20 km) of driving and the amount
of fuel remaining in the tank when the reading was taken.
When the driving distance on current fuel reserve is less than 12 miles
(20 km), “----” will be displayed in the text window.
2. Average fuel consumption
This value indicates fuel consumption since the last time the trip
computer was reset (by pressing RESET, button C). When the engine is
switched off, information on fuel consumption is stored and remains in
system memory until the RESET (button C) is pressed again.
3. Current fuel consumption
This value indicates the current fuel consumption, based on readings
taken once per second. When the car is not moving, “----” will be
displayed.
4. Average speed
This value indicates average speed since the last time the trip computer
was reset (by pressing RESET, button C). When the engine is switched
off, information on average speed is stored and remains in system
memory until the RESET (button C) is pressed again.
5. Current speed in miles per hour (Canadian models only)
This function provides the driver with an instantaneous conversion of the
car’s current speed from km/h to mph.

Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount
of condensation that forms on the windows. Use a commercial window
cleaning agent to clean the windows.

Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the
windows and moonroof (option) for several minutes before driving will
help release the warm air from the passenger compartment. When the
engine is running, close the windows and moonroof and use the
recirculation function for several minutes to enable the air conditioning
to cool the compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the windows and optional moon-
roof are closed. If you drive with the moonroof open, we recommend
that you manually adjust the temperature and blower control (the LED in
the AUTO switch should be off).

Climate control maintenance
Special tools and equipment are required to maintain and carry out
repairs on the climate system. Work of this type should only be done by
a trained and qualified Volvo service technician.

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).

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 Check Engine light (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

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 when refueling.
In addition to causing damage to the
environment, 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.

* Your car is equipped with an electronic start
inhibitor (immobilizer). The keys you received
with your car are specially coded. The code in
the key is transmitted to an antenna in the
ignition switch where it is compared to the
code stored in the start inhibitor module. The
car can only be started if a properly coded key
is used.
If two of the keys to your car are close
together, e.g., on the same key ring, when you
try to start the car, this could cause interfer-
ence in the immobilizer system and result in
the car not starting. If this should occur,
remove one of the keys from the key ring
before trying to start the car again.

Starting the engine
CAUTION:
•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 engage-
ment 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.
•Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.WARNING!
•Always place the gear selector in Park or
in reverse on models with a manual
transmission, and apply the parking brake
before leaving the vehicle. Never leave the
car 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.
•An extra mat on the driver's floor can
cause the accelerator pedal and the clutch
to catch. Check that the movement of the
accelerator pedal and clutch is not
impeded. Not more than one protective
floor covering may be used at one time.
