or when engine is running and vehicle
is stationary. Some functions remain
active until driver's door is opened,
provided the ignition was on
previously.Emergency shut off during driving
Press Start/Stop for about 3 seconds
3 154. Steering wheel locks as soon
as vehicle is stationary.
Steering wheel lock
The steering wheel lock activates
automatically when:
● The vehicle is stationary.
● The ignition has been switched off.
To release steering wheel lock, open
and close driver's door and switch the ignition on power mode or start the
engine directly.
154Driving 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,
a message may be displayed in the
Driver Information Centre.
Hold the electronic key with buttons
outside at the marking on the steering column cover as shown in the
illustration.
Operate the clutch pedal (manual
transmission), the brake pedal and
press Start/Stop .
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.Starting the engine
Vehicles with ignition switch
Turn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Diesel engines: wait until control
indicator z extinguishes.
Driving and operating155Turn key briefly to position 2 and
release after engine has been
started.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 156.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 156.
Vehicles with power button● Manual transmission: operate clutch and brake pedal.
● Automatic transmission: operate brake pedal and move selector
lever to P or N.
● Do not operate accelerator pedal.
● Press Start/Stop button.
● Release button after starting procedure begins. Diesel engine
starts after control indicator z
for preheating extinguishes.
● Before restarting or to switch off the engine when vehicle is
stationary, press Start/Stop once
more briefly.
To start the engine during an
Autostop:
● Manual transmission: during an Autostop, the engine can be
started by depressing the clutch
pedal 3 156.
● Automatic transmission: during an Autostop, the engine can be
started by releasing the brake pedal 3 156.Emergency shut off during driving
If the engine needs to be switched offduring driving in case of emergency,
press Start/Stop for 5 seconds.9Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
156Driving and operatingStarting 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 requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
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 pedal is released.Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system
The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.
Activation
The stop-start system is available as soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Without touchscreen
The system is ready to operate when
the LED in the button D is not
illuminated. To activate the system
when the system is deactivated,
press D. If the stop-start system is
temporarily not available and the
button D is pressed, the LED in the
button flashes.With touchscreen
The system can be activated in the
vehicle personalisation 3 123. If the
stop-start system is temporarily not
available, the control indicator D
flashes for a few seconds.
DeactivationWithout touchscreen
Press D to deactivate the stop-start
system. The deactivation is indicated
when the LED in the button
illuminates.
238Vehicle careTyre deflation detection
system
The tyre deflation detection systemcontinually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator q illuminates, a warning
chime is given and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator q 3 113.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction, the
control indicators q and R
appear at the same time or a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure
3 271.
2. Apply parking brake. 3. Start the initialisation procedure:
a) Vehicles without Infotainment
system: Press button q for 3
seconds. A chime confirms the
start.
b) Vehicles with Infotainment
system: Initialise the deflation
detection system in the vehicle
personalisation 3 123.
4. Reset is confirmed by pop-up indication.
242Vehicle care8. All of the sealant is pumped intothe tyre. Then the tyre is being
inflated.
9. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 271.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button.
Do not run the compressor longer than ten minutes.
10. Detach the tyre repair kit. Stow tyre repair kit in load
compartment.
11. Remove any excess sealant using a cloth.12. Start driving immediately so thatsealant is evenly distributed in the
tyre. After driving approx.
three miles but no more than ten
minutes, stop and check tyre
pressure. Turn selector on the kit
to the air pump symbol. Connect
compressor air hose to tyre valve. Fill tyre as described before. Drain excess tyre pressure with the
button on the kit.
If tyre pressure hasn't decreased
under 150 kPa (1.5 bar), set it to
the correct value. Otherwise the
vehicle must not be used. Seek
assistance of a workshop. 3 271
