The air distribution can adjusted with the but-
tons. To have the air distribution regulated auto-
matically, press the AUTO button.
The round air vents in the cockpit are adjustable
> page 68.
To keep the front side windows from fogging up
in damp weather, we recommend opening the
side air vents and tilting them to the side.
Foot vents are located under the front seats and
adjustable vents on the end of the center console
to heat the rear of the vehicle.
& Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (22°C) or higher. The temperature is
controlled automatically. In the & setting, the
A/C cooling mode switches on automatically, de-
pending on the outside air temperature.
The AUTO button switches the defroster off.
<> Recirculation mode
The recirculation mode can be turned on manual-
ly or automatically*.
— Switching manual recirculation mode on and
off: press the > button.
— Automatic* recirculation mode: auto recircula-
tion needs to be activated in the Infotainment
system. Select in the Infotainment system:
MENU] button > Vehicle > left control button >
Air conditioning > Auto recirculation. The air
quality sensor that is designed for diesel and
gasoline exhaust automatically switches the re-
circulation mode on or off depending on the
level of pollutants in the outside air.


In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior. Switching recirculation mode on
when driving through a tunnel or when sitting in
traffic is recommended > A.
Pressing the <> button, AUTO or the ® button
switches recirculation mode off.
@ Rear window heating
If the rear window defogger is activated when
the ignition is switched on, the battery manage-
ment determines based on the battery charge if
it is possible to turn on. Otherwise, the rear win-
dow defogger functions with the engine running
and switches off automatically after approxi-
mately 10 - 20 minutes, depending on the out-
side temperature.
To prevent the rear window defogger from
switching off automatically, press and hold the
® button for more than two seconds.
#/ Seat heating*
Pressing the a button switches the seat heating
on at the highest setting (level 3). The LEDs indi-
cate the temperature level. To reduce the tem-
perature, press the button again. To switch the
seat heating off, press the button repeatedly un-
til the LED turns off.
After approximately 10 minutes, the seat heating
automatically switches from level 3 to level 2.

Z\ WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these individuals should
not use seat heating.


@) Note
To reduce the risk of damage to the seat heat-
ing elements, do not kneel on the seats or
place heavy pressure on one area of the seat.

increases the risk of an accident.

@) Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You
could damage the engine.
— If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off and there is a risk of damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.

Drive system
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine and other drive com-
ponents.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
78
tion. The engine can be increased RPM gradually
during the next 300 miles (S500 km).
Conventional drive system
Applies to: vehicles with conventional drive system
Vehicles with a conventional drive system are
powered by a combustion engine. It uses fuel to
recover energy.
ate RMN elec: me Lah)
Applies to: vehicles with plug-in hybrid drive
With plug-in hybrid drive, you can select between
the electric and combustion engine drive systems
or combine them > page 79, > page 76.
Coasting
Applies to: vehicles with coasting function
Similar to vehicles with a conventional drive sys-
tem, plug-in hybrid drive vehicles can also disen-
gage the combustion engine to save fuel. The ve-
hicle rolls without an engine braking effect in this
mode, which is “similar to coasting”. However,
the electric portion of the drive system remains
engaged and recuperates if necessary. You can
activate the coasting function in the “D” driving
program up to approximately 112 mph
(180 km/h). This occurs automatically when you
take your foot off the accelerator pedal.
Applies to: vehicles with plug-in hybrid drive
The vehicle is able to recover energy by using “re-
cuperation”. The electric drive system operates
like a generator and converts a large portion of
kinetic energy into electrical energy that is stored
in the high-voltage battery. The vehicle is braked
during recuperation, which is similar to the en-
gine braking effect on a vehicle with a combus-
tion engine. This will happen automatically when
you press the brake pedal while driving in “D”
gear, or when you remove your foot from the ac-
celerator pedal.
The energy recovery is displayed in the energy
flow display > page 80. The recuperation
