System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 188.
The engine is switched off automatically; when moving off, the ignition
process will be initiated automatically.
The engine is not switched off automatically.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶
The engine temperature for the proper function of the system has not yet
been reached.
▶
The charge state of the vehicle battery is too low.
▶
The current consumption is too high.
▶
High air conditioning or heating output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en-
gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
More information about the current system status can be displayed in the In-
fotainment screen, in the

menu.
If there is a system fault, the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.
Note
■
If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted manually.
■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shut-down
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Braking and parking
Introduction
The wear and tear on the brake pads is dependent on the operating conditions
and driving style. In difficult conditions (e.g. urban, sporty driving), the condi-
tion of the brakes should be checked between services by a specialist garage.
Brake response can be slower if the brakes are covered in moisture or, in
winter, have a layer of ice or salt on them. The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehi-
cle has been parked for a long period and if you do not make much use of the
braking system. The brakes should be cleaned by applying the brakes several
times over » .
