22Keys, doors and windowsElectronic key system
Enables a handsfree operation of thefollowing functions:
● central locking system 3 23
● load compartment 3 31
● ignition switching on and starting the engine 3 114
The electronic key simply needs to be on the driver's person.
Notice
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 90 and a message in the
Driver Information Centre (DIC)
3 90 when the driver's door is
opened.
Additionally, the electronic key
includes the functionality of the radio
remote control 3 20 and an entry
lighting function 3 100.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Notice
Do not put the electronic key in the
load compartment during driving, as
this is outside of the detection zone
(indicated by a warning chime at low
speed 3 90 and a message in the
Driver Information Centre (DIC)
3 90).
Handsfree operation is automatically disabled when the electronic key
buttons have been operated or the
central locking switch e 3 23 is
pressed. To re-enable handsfree
operation, restart the engine.
Power button 3 114.Replacing battery in electronic
key
Replace the battery as soon as the
system no longer operates properly
or the range is reduced. The need for
battery replacement is indicated by a
message in the DIC 3 90.
Battery replacement, see Radio
remote control 3 20.
Fault
If the central locking system cannot
be operated or the engine cannot be
started, the cause may be one of the
following:
● fault in electronic key
● electronic key out of reception range
● battery voltage too low
● overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time
● interference from higher-power radio waves from other sources

Heated rear window 3 40.
Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
AC:cooling4:air recirculation
Heated seats 3 45.
Cooling (AC)
Press AC to switch on cooling.
Activation is indicated by illumination
of the LED in the button. Cooling is
only functional when the engine is
running and climate control fan is switched on.
Press AC again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. 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 an Autostop.
Stop-start system 3 117.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 112.
Air recirculation system 4
Press 4 to activate air recirculation
mode. Activation is indicated by
illumination of the LED in the button.Press 4 again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling, the
air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and avoid the use
of air distribution settings J and V.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
● Cooling AC on.
● Air recirculation system 4 on.
● Set air distribution control to M.
104Climate controlIf the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set, the climate control system runs at
maximum heating.
Demisting and defrosting the
windows
● Press Ê; LED illuminates in the
button when activated.
● Temperature, air distribution and cooling are regulated
automatically and the fan runs at
high speed.
● Switch on heated rear window Ü
