Driving and operating133Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be inhibited to allow for charging the
vehicle battery.

Retained power off
The following electronic systems can
work until the driver's door is opened
or at the latest for 10 minutes after the
ignition is switched off:
■ Power windows
■ Power outlets
Power to the Infotainment system will continue to operate for 30 minutes oruntil the key is removed from the
ignition, 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 accelerator pedal.
Page 136 of 237

134Driving and operating
Diesel engine: turn the key to position2 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
The start of 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.Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission)
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission)
■ Timeout occurred
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Page 142 of 237

140Driving and operating
Without brake pedal applied, the
control indicator j illuminates.
If the selector lever is not in P when
the ignition is switched off, the control
indicator j and P flash.
To engage P or R, press the release
button.
The engine can only be started with the lever in position P or N. When
position N is selected, press the brake
pedal or apply the parking brake
before starting.
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Engine braking To utilise the engine braking effect,select a lower gear in good time when
driving downhill, see manual mode.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
Apply the parking brake and engage P .
The ignition key can only be removed
when the selector lever is in position
P .Manual mode
Move selector lever out of position D
towards the left and then forwards or backwards.
<=Shift to a higher gear.]=Shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed. This can
cause a message in the Driver
Information Centre.
Page 143 of 237

Driving and operating141
In manual mode no automatic shiftingto a higher gear takes place at high
engine revolutions.
Electronic driving
programmes ■ Following a cold start, the operating
temperature programme increasesengine speed to quickly bring the
catalytic converter to the required
temperature.
■ The automatic neutral shift function
automatically shifts to idling when
the vehicle is stopped with a
forward gear engaged and the
brake pedal is pressed.
■ Special programmes automatically adapt the shifting points when
driving up inclines or down hills.
Kickdown If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear depending on engine speed.Fault
In the event of a fault, g illuminates.
Additionally a code number or a
vehicle message is displayed in the Driver Information Centre. Vehicle
messages 3 103.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.
Only the highest gear is available.
Depending on the fault, second gear
may also be available in manual
mode. Shift only when vehicle is at a
standstill.
Have the cause of the fault remedied
by a workshop.
Interruption of power
supply In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.If the vehicle battery is discharged,
start the vehicle using jump leads
3 200.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.
2. Hold the selector lever trim at the marked position and pull tounlatch at the back.
3. Fold the selector lever trim upwards. Pull to unlatch at the
front.
