Engine Braking Support
(assistance when driving downhill)
The Engine Braking Support system is an assist-
ance system which helps the driver when driving
slowly downhill at speeds up to approx. 20 km/h
(12 mph), e.g. on steep slopes or on wintry
mountain roads.
Engine Braking Support is active and brakes the
vehicle as long as the accelerator is not used
when travelling downhill.
If road grip is lost on one or more wheels, the
system brakes the wheels which have good road
contact.
Like all brakes, the braking ability of the Engine
Braking Support system is impaired by slippery
surfaces (e.g. on icy or loose surfaces).
d
Warning!
Risk of accident. Reduced braking ability on
a slippery surface.
f
Always adjust your driving style to the driving
situation.

ling downhill.
