Functional requirements of the auxiliary heating (aux. heating and ventilation) The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning light is not illuminated in the
instrument cluster).
Aux. heating
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The auxiliary heating also warms up the engine.
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
For vehicles with gasoline engines, the automatic switching on and off of the
heater can be disabled in a specialist workshop.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
109Heating and ventilation

Under certain circumstances (e.g. after switching off the ignition and opening
the driver's door), the steering is enabled only when the ignition is switched on
or the engine is started.WARNINGNever let the vehicle roll with locked steering lock - there is a risk of acci-
dent!

to start.
On vehicles fitted with a automatic gearbox, the brake pedal must not be de-
pressed while switching the ignition on or off, otherwise the system would try
to start.
If the driver's door is opened while the ignition is on, an audible signal sounds
and the following message appears in the instrument cluster display.

out.
Note
■ The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem.■
You should not switch on any major electrical components during the heat-
ing period otherwise the vehicle battery will be drained unnecessarily.

Emergency shutdown
If necessary and in exceptional cases, the engine may even be turned off while
driving.
›
Press the starter button » Fig. 130 on page 115 for longer than 1 second or
twice within 1 second.
After the emergency stop of the motor, the steering lock will remain unlocked.
CAUTION
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumula-
tion of heat when the engine is switched off.
Note
After switching off the ignition, the radiator fan may intermittently continue to
operate for approx. 10 minutes.1)
On vehicles with the START-STOP system, it is sufficient to press the starter button briefly. The motor
will then automatically start.

Information messages
119
The START STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
The system function depends on many factors. Some of them are down to the
driver, the others are systemic and can neither be influenced nor identified.
Therefore the system may react differently in situations which seem identi-
cal from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even where this has previously been manually deactivated with the button ).
Note
If the engine has stopped due to the system, the ignition remains on.117Starting-off and Driving

OperationFig. 132
Prompt in the MAXI DOT display
Vehicles with manual transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt, the shift lever is moved into neutral and the clutch pedal is released.
The engine is automatically started as soon as the clutch pedal is depressed.
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 brake pedal is released.
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 bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
System status
The system status is indicated in the instrument cluster display when stopped.
The engine is automatically switched off; when the vehicle moves off the igni-
tion process will be automatically initiated.
» Fig. 132
START-STOP ACTIVE
The engine is not automatically switched off.
» Fig. 132
START-STOP NOT POSSIBLEReasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ 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 capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
When the engine is shut-down automatically and the system detects that the engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
Note
■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during 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 shutdown
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.
