Braking on slopes
ATTENTION
 When travelling downhill for extended periods of time, the ser-
vice brake may overheat and become damaged!
 Keep the engine running when driving downhill. Use the
brake in addition, when necessary.
 Accident hazard through non-intended use of brake – do not
use the brake pedal as a footrest.
If the service brake is used excessively when driving downhill, it
may overheat and become damaged.
Prevent this by driving downhill slowly and using the braking force
of the engine.

An alarm buzzer sounds if the maximum permitted travel speed
is exceeded by 10%.
