Using The Forward Collision Warning - SMART forfour Owner's Manual

Driving safely

When you switch on the ignition, the !
warning lamp in the instrument cluster
lights up. It goes out after the engine is star-
ted.
ABS works from a speed of about 6 km/h,
regardless of road-surface conditions. ABS
intervenes in the case of slippery road sur-
faces, even when you only brake gently.
X
To brake while ABS intervenes: continue to
depress the brake pedal with force until
the braking situation is over.
X
To make a full brake application: depress
the brake pedal with full force.

WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety sys-
tems are deactivated. There is an increased
danger of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.

Using the forward collision warning

Useful information
If a risk of collision with the vehicle in front
is detected, the forward collision warning
alerts the driver both visually and acousti-
cally.
With the help of the radar sensor system, the
forward collision warning can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of approximately 70 km/h, the
forward collision warning can react to sta-
tionary obstacles, such as stationary or
parked vehicles.
Please note
i Observe the notes in the "Limitations of
the driving safety systems" (
section.

The distance warning function may not

There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Always adapt your speed to suit the pre-
vailing road and traffic conditions.

The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
give an unnecessary warning
R
not give a warning

There is a risk of an accident.
Always pay careful attention to the traffic
