specific, and optional equipment offered with
the series. It also describes features and func-
tions that are not necessarily available in the

Brake assistant
The brake assistant automatically applies
maximum braking assistance when the brake
pedal is depressed quickly. This reduces the
braking distance to a minimum for full braking.
To make full use of braking assistance, do not
reduce the pressure on the brake pedal during
full braking.
Drive-off assistant
Principle
The drive-off assistant supports driving off on
uphill grades.

pedal.
