System limits
Safety information
Warning
The system is designed to operate in certain
conditions and circumstances. Due to condi‐
tions or other factors, the system may not re‐
spond. There may be a risk of accident or risk
of damage to property. Actively intervene as
warranted. Refer to the information in this Own‐
er’s Manual regarding the scope of the sys‐
tem’s operation and limitations.
Upper speed limit
If the vehicle speed exceeds approx.
155 mph/250 km/h, the system is deactivated
temporarily.
If the vehicle speed falls below approx.
155 mph/250 km/h, the system once again re‐
sponds according to the setting.
Functional limitations
The system may not be fully functional in the fol‐
lowing situations:
▷
When a vehicle is approaching at a speed
much faster than your own.
▷
In heavy fog, wet conditions, or snowfall.
▷
In tight curves or on narrow lanes.
▷
If the bumper is dirty, iced up, or covered,
for instance by stickers.
▷
If cargo protrudes.
Attaching any objects such as stickers or film in
the beam area of the radar sensors will also im‐
pact the function of the radar sensors and may
even cause them to fail.
A Check Control message is displayed when the
system is not fully functional.
Displaying warnings
Depending on the selected warning settings, for
instance warning time, more warnings can be
displayed. However, there may also be an excess
of premature warnings of critical situations.
PostCrash – iBrake
Concept
In the event of an accident, the system can bring
the vehicle to a halt automatically without inter‐
vention by the driver in certain situations. This
can reduce the risk of a further collision and the
consequences thereof.
At standstill
After coming to a halt, the brake is released auto‐
matically.
Harder vehicle braking
In certain situations, it can be necessary to bring
the vehicle to a halt more quickly than the Brake
Assistant allows.
To do this, quickly apply extra force to the brake.
For a brief period, the braking pressure will be
higher than the braking pressure that is achieved
by the automatic braking function. Automatic
braking is interrupted.
Interrupting automatic braking
It can be necessary to interrupt automatic brak‐
ing in certain situations, for instance for an eva‐
sive maneuver.
Interrupt automatic braking:
▷
By pressing the brake pedal.
▷
By pressing the accelerator pedal.
