On-Board Diagnostics II (OBDII): As you
drive, a computer called “OBDII” monitors
your car’s engine, transmission, electrical and
emission systems. The CHECK ENGINE
light will light up if the computer senses a
condition that potentially may need correcting.
When this happens, please have your car
checked by a Volvo retailer as soon as
possible.

WARNING!
•Bumper-attached trailer hitches must not be used on Volvo’s, nor
should safety chains be attached to the bumper.
•Trailer hitches attaching to the vehicle rear axle must not be used.•Never connect a trailer’s hydraulic brake system directly to the
vehicle brake system, nor a trailer’s lighting system directly to the
vehicle lighting system. Consult your nearest authorized Volvo
retailer for correct installation.
•When towing a trailer, the trailer’s safety wire must be correctly
fastened to the hole or hook provided in the trailer hitch on the car.
The safety wire should never be fastened to or wound around the
drawbar ball.
NOTE:
•When parking the car with a trailer on a hill, apply the parking
brake before putting the gear selector in (P)ark or reverse on
models with a manual transmission. Always follow the trailer
manufacturer's recommendations for wheel chocking.
•When starting on a hill, put the gear selector in (D)rive before
releasing the parking brake.
•If you use the manual (Geartronic) shift positions while towing a
trailer, make sure the gear you select does not put too much strain
on the engine (using too high a gear).
•The drawbar assembly/trailer hitch may be certified for trailers that
are heavier than the car is designed to tow. Please adhere to Volvo’s
recommended trailer weights.
* When driving for prolonged periods at temperatures above 86° F
(30° C), the maximum recommended weight is 2000 lbs (900 kg).
When preparing for trailer towing, observe
the following:
Volvo recommends the use of Volvo trailer hitches which are specially
designed for the car.

Water 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 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 towing. 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.

NOTE: When the car is at a standstill and the engine is idling, e.g. at a
traffic light and the brake pedal is depressed, the pedal may go down
slightly. This is normal and is caused by an built-in function in the
power brake system.
Power brakes function only when the engine
is running
