even more quickly when braking in critical situa‐
tions.
Vehicle equipment
This chapter describes all standard, country-spe‐
cific and optional equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the spe‐
cial equipment selected or the country specifica‐
tion. This also applies to safety-relevant func‐
tions and systems. Please comply with the
relevant laws and regulations when using the
corresponding functions and systems.
Drive-off assistant
Principle
The system provides support when driving off on
upward gradients.
Driving off
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive off without
delay.
Anti-lock Brake System
ABS
After the foot brake is released, the vehicle is
held in place for approximately 2 seconds.
ABS prevents the wheels from locking when the
brakes are applied.
Depending on the vehicle's load or when towing
a trailer, the vehicle may roll backwards a little.
Steering control is retained even during full brak‐
ing, which enhances active road safety.
Dynamic Stability Control
DSC
ABS is operational each time the engine is star‐
ted.
Principle
Brake assist
The system reduces engine power output and
applies the brakes on individual wheels thereby
helping, within the limits imposed by physics, to
keep the vehicle safely on course.
When the brake pedal is depressed quickly, the
system automatically applies maximum braking
power. This keeps the stopping distance as short
as possible in full braking situations. The advan‐
tages offered by the Anti-lock Brake System
ABS can also be utilised to the full.
General
DSC detects the following unstable driving con‐
ditions, for example:
The pressure on the brake should be maintained
for the duration of the full-braking process.
▷ Loss of traction at the rear which can lead to
oversteer.
▷ Loss of grip at the front wheels which can
lead to understeer.
Adaptive brake assist
In conjunction with Active Cruise Control ACC,
this system ensures that the brakes respond
