4. Information display - The display presents information and warning messages, the ambient temperature, and the
clock, etc. When the ambient temperature is between 23° and 36°F (-5° and +2°C), a snowflake symbol is shown in
the display. This symbol serves as a warning for possible slippery road surfaces. Please note that this symbol does not
indicate a fault with your car. At low speeds, or when the car is not moving, the temperature readings may be slightly
higher than the actual ambient temperature.
5. Information symbol - See the following pages for additional information.
6. Turn signal, right
7. Tachometer - Shows engine speed in thousands of revolutions per minute (rpm). Do not drive continuously with the
needle in the red area of the dial, which indicates maximum allowable engine rpm range. Instead, shift to a higher gear
or slow the vehicle down. The engine management system will automatically prevent excessively high engines speeds.
This will be noticeable as a pronounced unevenness in engine speed.

Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
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.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your vehicle, lead has been strongly linked to certain forms of cancer. Many fuels
contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you live in an
area where you must fill your own gas tank, take precautions.
These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during
refueling
wearing neoprene gloves while handling a fuel filler nozzle.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to a trained and qualified Volvo service technician for correction.
Use of Additives
With the exception of fuel line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
Fuel filler door
Press the button on the light switch panel (see the illustration on page 59
) with the ignition switched off to unlock the
fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An
audible click will be heard when the fuel filler door relocks.
134 06 Starting and driving
Fuel requirements

needed, depress the pedal occasionally when driving through rain, slush, etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that if
you are towing a trailer, the brakes will be subjected to a greater than normal load.
Anti-lock brakes (ABS)
The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking
conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically
modulated in order to help prevent lockup that could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 m.p.h. (20 km/h). The brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
148 06 Starting and driving
Brake system
For optimal ABS braking effect:
1. Press down on the brake pedal with full force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel and keep the brake pedal depressed.
Electronic Brake Force Distribution (EBD)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic pressure to the rear brakes to help provide
optimal braking capacity.
The switching of the ABS modulator will be audible and the brake pedal will pulsate during braking. Please be aware
that ABS does not increase the absolute braking potential of the vehicle. While control will be enhanced, ABS will not
shorten stopping distances on slippery surfaces.
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection.
WARNING
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest trained and qualified Volvo service
technician to have the brake system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. Maintain full pressure on the brake pedal in order to utilize the system completely.

205 09 Maintenance and servicing
Engine oil
Changing engine oil and oil filter
See page 253
for oil specifications. Refer to the Warranty and Service Records Information booklet for information on
the oil change intervals.
Volvo recommends Castrol.
NOTE
Volvo does not recommend the use of oil additives.

Volvo service technician.
NOTE
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
207 09 Maintenance and servicing
Fluids
CAUTION
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly!
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools. If it is necessary to top off the
coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates.
Brake fluid
The brake fluid should always be between the MIN and MAX marks on the side of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary to
replace the fluid more often. Consult your Volvo retailer. Always entrust brake fluid changing to a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level is checked at each service interval.
