● If a door or the tailgate is not fully
closed when starting off.
● If a certain speed is exceeded with parking brake applied.
● If a programmed speed is exceeded.
● If a warning message appears in the Driver Information Centre orInfo-Display.
● If the parking assist detects an object.
● If unintended lane change occurs.
● If a fault in the automatic locking system is detected.When the vehicle is parked and/or
the driver's door is opened
● With exterior lights on.
During an Autostop ● If the driver's door is opened.
Battery voltage
When the vehicle battery voltage is
running low, the warning code 174 will
appear in the Driver Information
Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe drive, e.g.
seat heating, heated windscreen
and heated rear window or other
main consumers.
2. Charge the vehicle battery by driving continuously for a while or
by using a charging device.
The warning code will disappear after the engine has been started twice
consecutively without a voltage drop.
If the vehicle battery cannot be
recharged, have the cause of the fault
remedied by a workshop.

displayed menu.
The electronic climate control system
is only fully operational when the
engine is running.
Heating will not be fully effective until
the engine has reached normal
operating temperature.
Automatic mode AUTO
The system automatically controls the
fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to the desired temperature.
When the AUTO indicator light is on,
the system is in full automatic
operation.
If the air delivery mode, fan speed,
recirculation, or air conditioning
setting is adjusted, the AUTO
indicator turns off.
To improve fuel efficiency and to cool
the vehicle faster, recirculation may
be automatically selected in warmweather. The recirculation light will
not come on. Press 4 to select
recirculation; press it again to select
outside air.
To turn off the system, press power m.
Basic setting for maximum comfort: ● Press AUTO. The LED in the
button illuminates to indicate activation.
● Open all air vents to allow optimised air distribution in
Automatic mode.
● Set the preselected temperature.
Recommended temperature is
22 °C.
Temperature preselection Set temperature to the desired value.
It is indicated on the display in the
temperature control.
For reasons of comfort, change
temperature only in small increments.
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling A/C is
active.

Notice
If A/C is switched on, reducing the

Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
Driving with recirculation mode for
a prolonged period of time can
make you sleepy. Periodically turn to the outside air mode for fresh
air.
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the
vehicle occupants to feel drowsy.
In warm and very humid ambient air
conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate V.
Manual settings Climate control system settings can
be changed by activating the buttons
and rotary knobs as follows.
Changing a setting will deactivate
Automatic mode.
102Climate controlService
For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Driving and operating107Deactivation
Deactivate the stop-start system
manually by pressing Ï. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop
Vehicles with manual transmission
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.The engine will be switched off while
the ignition stays on.Vehicles with manual transmission
automated
If the vehicle is at a standstill with the brake pedal depressed, 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 15% or more.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
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 bonnet is fully closed.
● 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 above -5 °C.
● The climate control system allows an Autostop.
108Driving and operating● The brake vacuum is sufficient.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
"Climate control" chapter for further
information 3 97.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 104.
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, e.g., the rear window
heating, are disabled or switched into a power saving mode. The fan speed
of the climate control system is
reduced to save power.Restart of the engine by the driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in
the Driver Information Centre.
Control indicator - 3 69.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
