dehumidifies (dries) as soon as the
outside temperature is slightly above the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit

134Driving 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.
Operate the clutch pedal (manual
transmission), the brake pedal and
press Start/Stop . Release the button
after starting procedure begins.
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 mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving
mode
When power saving mode is
activated, a message appears in the Driver Information Centre indicating
Power saving mode .
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.
Driving and operating135Deactivating power saving modePower saving mode is deactivated
automatically when the engine is restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes
Starting the engine
Vehicles with ignition switch● Turn key to position 1.
● Move the steering wheel slightly 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 ! extinguishes.
● Turn key to position 2 and
release after the engine has been started.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 137.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 137.Vehicles with power button

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.
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 requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .
Heating functionalities
Note
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
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.
Driving and operating137Stop-start systemThe 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.
DeactivationDeactivate the stop-start system
manually by pressing Ò. The
deactivation is indicated when the
LED in the button illuminates.
AutostopVehicles with manual transmission
An Autostop can be activated at a
standstill.
Activate an Autostop as follows: ● Depress the clutch pedal.
● Set the lever to neutral.
● Release the clutch pedal.
The engine will be switched off while
the ignition stays on.Vehicles with automatic transmission If the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while the ignition stays on.
The stop-start system will be disabled
on inclines of 12% or more.Indication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
Driving and operating149Manual parking brake9Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Control indicator R 3 91.
Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Ride control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the
wheels are braked individually.
ESC operates in combination with the Traction Control system (TC). It
prevents the driven wheels from
spinning.
The TC is a component of the ESC.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
