Operation in Infotainment

The auxiliary heating heats the vehicle interior as well as the engine. For heat-
ing, fuel is consumed from the fuel tank.
The auxiliary ventilation enables fresh air to flow into the vehicle interior with
the engine switched off, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
The auxiliary heating (auxiliary heating and ventilation) (referred to just as aux- iliary heating in the following) ensures the heating / ventilation depending on
the setting of the air conditioning and the air outlet vents before switching off
the ignition.WARNING■ The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the auxiliary heating, do not park the car in
places where the exhaust fumes can come into contact with flammable
materials such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of
fire.
CAUTION
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
In the engine compartment, water vapour may form during the operation of
the heater.

Switching off the auxiliary heating takes place automatically when there is a
lack of fuel (warning light in the instrument cluster lights up).
After switching off the system, the coolant pump and the auxiliary heating will
continue running a little while longer in order to burn the remaining fuel in the
heating.

201Vehicle systems

Vehicles with automatic transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt and the brake pedal is operated.
The engine is automatically started as soon as the accelerator pedal is de-
pressed or the brake pedal is released (with deactivated Auto Hold function).
Requirements for the system to function correctly
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed was higher than 4 km/h after the last stop.
The OFF ROAD mode is enabled.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 253 .
The engine is switched off automatically; when moving off, the ignition
process will be initiated automatically.
The engine is not switched off automatically.
When stopping, the engine will not switch off for the following reasons,
among others. ▶ 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 blower speed, big difference be-
tween the desired and actual interior temperature).
If the engine is shut down automatically and the system detects that the en- gine is required, such as when the brake pedal is pressed repeatedly, then the
system automatically starts the engine.
More information about the current system status can be displayed in infotain-
ment screen, in the
→
→
Vehicle status
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 approx. 30 seconds or the
driver's door is opened during automatic stop mode, the engine will have to be
started 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.

ABCProactive passenger protection (Crew Protect Assist)
Introduction
This chapter contains information on the following subjects:
Function
253
ProActive passenger protection (following known as system) increases pas-
senger protection in the front seats in situations that could lead to vehicle im-
pact or overturning.
WARNINGPlease take note of the general points relating to the use of assistance
systems » page 215, in section Introduction .
Note
■
The system component service life is monitored electronically. Further infor-
mation » page 37 , Safety systems .■
If the front passenger front airbag is deactivated, the belt tensioning func-
tion for the front passenger seat is switched off.
Function
Read and observe
on page 253 first.
In critical driving situations (e.g. during emergency braking or a sudden changein direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
▶ The front passenger's and driver's seatbelts, if worn, are automatically ten-
sioned closely over the body.
▶ Opened door windows in the front doors are automatically closed up to a gap
of about 5 cm from the edge.
▶ The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.
