136Driving and operating9Warning
If the vehicle battery is discharged,
the vehicle must not be towed,
tow-started or jump-started as the
steering wheel lock cannot be
disengaged.
Operation on vehicles with
electronic key system in case of
failure
If either the electronic key fails or the
battery of the electronic key is weak,
the Driver Information Centre may
display No Remote Detected or
Replace Battery in Remote Key when
you try to start the vehicle.
Hold the electronic key with buttons outside at the marking on the steering column cover as shown in the
illustration.
Depress the clutch pedal (manual
transmission) or the brake pedal
(automatic transmission or manual
transmission automated) and press
Start/Stop button to start the engine.
This option is intended for
emergencies only. Replace the
electronic key battery as soon as
possible 3 23.
For unlocking or locking the doors,
see fault in radio remote control unit
or electronic key system 3 24.
Power saving mode
This function manages the duration of
using certain systems to avoid
discharging of the vehicle battery.
After the engine has stopped, some
systems can still be used such as the audio and telematics system,
windscreen wipers, dipped beam
headlamps, courtesy lamps, etc. for a total maximum time of about forty
minutes.
Changing into power saving
mode
When a certain discharging status of
the vehicle battery is achieved, the
active functions are switched in
standby mode. A message appears in the Driver Information Centre
indicating Power saving mode .
A telephone call being made at this
time will be maintained for around 10
minutes with the Bluetooth handsfree
system of the Infotainment system.
Driving and operating141● 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.
● 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 or
switching off ignition on
vehicles with power button. 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
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows.
● 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 3 204.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
switched off automatically if the
vehicle comes to a standstill within a
certain time.
Driving and operating143Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 193, 3 243 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
AdBlue
General information
The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust
system. The ammonia released by
the fluid reacts with nitrous gases
(NO x) from the exhaust and turns it
into nitrogen and water.
The designation of this fluid is
AdBlue ®
. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
The typical AdBlue consumption is
approx. 0.85 l per 600 miles, but can
also be higher depending on driving
behaviour (e.g. high load or towing).
AdBlue tank
At a remaining volume of approx. five litres, there is a liquid level switch.
Warning messages are displayed
only below that threshold. Tank
volume 3 245.
