1987 Volvo 760
Do not park your car 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), with an intermittently-firing or flooded engine,
can cause catalyst or exhaust system overheating. This also applies to lengthy pushing or towing of
vehicle to start (manual transmissions only).
NOTE: Unleaded fuel is required for cars with catalytic converter. A label on the instrument
panel and inside fuel tank filler door will remind owners and filling station attendants of this
requirement.
Important! It is unlawful to dispense leaded fuel into any vehicle labeled "unleaded gasoline only".
pg. 59 Brake system
If one of the brake circuits should malfunction, the red warning light will come on
The pedal stroke increases slightly and the pedal feels softer but the pedal pressure required does not
increase noticeably.
If the red warning light comes on: stop immediately, open the hood and check brake fluid level (see
"Brake fluid, power steering" section).
Fluid level below MIN mark: do not drive. Tow car to shop for check/repair of brake system.
Fluid level between MIN and MAX mark: proceed with extreme caution to a Volvo dealer for an
inspection of the brake system.

If the brake power-assist does not function-

The power assist to the brakes functions only when the engine is running. When the car is moving
without the engine running the brake pedal pressure required to stop the car is increased by 3-4 times.
The brake pedal feels stiff and hard.

Moisture on brake discs and brake pads affects braking.

Driving in rain and slush or passing through an automatic car wash can cause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the pedal is depressed. To avoid
such a delay when the brakes are 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 weather.

Severe strain on the brake system

The brakes will be subject to severe strain when driving in mountains or hilly areas. The speed is
usually low which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes it is advisable not to use the brakes excessively.
