Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre (DIC).
1. Switch off immediately any electrical consumers which are
not required for a safe ride, e.g.
seat heating, 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 message will disappear after the engine has been started
twice consecutively without a voltage
drop.
If the vehicle battery cannot be

Vehicle battery state of charge
function
The function guarantees longest
vehicle battery life via a generator
with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in two stages and finally switched off:
■ auxiliary heater
■ heated rear window and mirrors
134Driving and operating
■ power windows
■ power outlets
Power to the Infotainment system will continue to operate for 30 minutes oruntil the key is removed from theignition switch, regardless of whether
any door will be opened.
Starting the engine
Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate the accelerator pedal.
Diesel engine: turn the key to position 2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
'Automatic Starter Control'.
Before restarting or to switch off the engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.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 needs a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running after a short delay.
Driving and operating137
Restart of the engine by the
driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre (DIC).
Control indicator - 3 90.
Restart of the engine by the
stop-start system The selector lever has to 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
DIC.
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.
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.
Activate the manual parking
brake without pressing the
release button. Apply as firmly
as possible on a downhill slope
or uphill slope. Depress foot
brake at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
approx. one second.
The electric parking brake is
applied when control indicator
m illuminates 3 90.
■ Switch off the engine. ■ If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector lever
to position P before removing
the ignition key. 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 before removing the ignition
138Driving and operatingkey. Turn the front wheels
towards the kerb.
■ Close the windows and the soft top.
■ Remove the ignition key. Turn the steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
■ Lock the vehicle.
■ Activate the anti-theft alarm system.
■ The engine cooling fans may run after the engine has been switchedoff 3 185.
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.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
