Recommended temperature is 22 °C .
Temperature is indicated in displays

switched on.
If the maximum temperature Hi is set,
the climate control system runs at

Note
If A/C is switched on, reducing the

Driving and operating125●Do not operate accelerator pedal.
● Diesel engines: wait until control indicator ! extinguishes.
● Turn key to position 2 and
release after the engine has been started.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 126.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 126.
Vehicles with power button● Manual transmission: operate clutch and brake pedal.
● Automatic transmission: operate brake pedal and move selector
lever to P or N.
● Do not operate accelerator pedal.
● Press Start/Stop button. Release
button after starting procedure
begins.
● Diesel engine starts after control indicator ! for preheating
extinguishes.
● Before restarting or to switch off the engine when vehicle is
stationary, press Start/Stop once
more briefly.
To start the engine during an
Autostop:
● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 126.
● Automatic transmission: during an Autostop, the engine can be
started by releasing the brake
pedal 3 126.Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines.
Required is an engine oil with the
correct viscosity, the correct fuel,
performed services and a sufficiently
charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position
P .Caution
Under extreme cold temperatures,
idle engine for maximum
5 minutes otherwise the engine
might be damaged.

Driving and operating127The engine will be switched off whilethe ignition stays on.Vehicles with automatic transmission
If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while
the ignition stays on.
The stop-start system will be disabled
on inclines of 12% or more.
Indication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is not too low or too high.
● The climate control system allows an Autostop.
● The brake vacuum is sufficient.
● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.Note
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 110.
If an autostop is temporarily not
available, D flashes green 3 86.
Immediately after driving at a higher
speed an Autostop may be inhibited.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
