The effectiveness of the brakes is an
important factor for traffic sa fe ty.
To improve effectiveness, do not brake

detailed in the chapter "Service,
Maintenance" on pag e 165 is therefore of
the utm os t importance for traffic safe ty.

Each time the ignition is switc he d on and
the e ngine is starte d, afte r se tting off at a
speed of about 3 km /h (2 mph), the system
performs a s elf-check which may be
