Climate control143Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service 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 operating151● The engine exhaust temperatureis not too high, e.g. after driving
with high engine load.
● The ambient temperature is not too low.
● 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.
Climate control 3 133.
Immediately after higher speed
driving an Autostop may be inhibited.
New vehicle running-in 3 145.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.
Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without
depressing the brake pedal to restart the engine.Vehicles with automatic transmission
The engine is restarted if
● the brake pedal is released while
the selector lever is in position D
or M
● or the brake pedal is released or the selector lever is in position N
when the selector lever is moved
to position D or M
● or the selector lever is moved to position R.
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 driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
152Driving and operating● The charging level of the vehiclebattery 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 an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake.
● If the vehicle is on a levelsurface or uphill slope, engage
first gear or set the selector
lever to position P. On an uphill
slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P . Turn the front wheels
towards the kerb.
● Close the windows.
● Switch off the engine.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
button. Turn the steering wheel until the steering wheel lock is
felt to engage.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 214.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
Emergency operation under
extreme cold temperatures
9 Warning
This emergency operation may
only be carried out in case of
extremely cold temperatures and if the vehicle is parked on a levelsurface.
