reduces the noise of the seat ventilation. Problems with the seat heating / seat ventilation
Problem
Possible causes/consequences and
M MSolutions The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical consum-
ers are switched on.
X Switch off electrical consumers that you do not need, such as the
rear window heating or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation can be switched back on manually. 106

AIRSCARF
Switching on/off G
WARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot. The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.
The warm air flows out of the holes in the head
restraints.
The three red indicator lamps in the button dis-
play the heating level you have selected.
X Make sure that the key is in position 1or2in
the ignition lock.
X To switch on: press button:.
Three red indicator lamps in the button light
up. The blower starts up after a seven second
preheating phase.
X Press button :repeatedly until the desired
heating level is set.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
Adjust the height of the current of air according
to your height by adjusting the height of the
head restraint.
Make sure that there are no objects covering the intake grille on the back of the driver's seat headrestraint.
i The blower runs for a further seven seconds
to cool down the heating elements.
i If the vehicle battery voltage is too low, AIR-
SCARF may switch off. Steering wheel

Optimum use of automatic climate con-
trol The following contains notes and recommenda-
tions on how best to use THERMATIC automatic
climate control.
R Activate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
DYNAMIC SELECT switch (except
Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT switch:
R manual transmission (Y page 141)
R automatic transmission (Y page 141)
If you have selected drive program E:
R during heating, the electrical heater booster
is deactivated and heat output is reduced as a
result
R the rear window heating running time is
reduced If you have selected drive program
C,Sor S+,
the current climate settings are maintained.
ECO start/stop function During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 139). Operating the climate control system
Switching the climate control on/off
General notes When climate control is switched off, the air
supply and air circulation are also switched off.
The windows could mist up. Therefore, switch
off climate control only briefly.
Switch on climate control primarily using the
à rocker switch (Y page 127).
Activating/deactivating X
Turn the key to position 2in the ignition lock
(Y page 133).
X To switch on: set the airflow to level 1or
higher using the Hrocker switch.
X To switch off: set the airflow to level 0using
the H rocker switch. 126
Operating the climate control systemClimate control

The climate control system switches to the
following functions:
R high airflow
R high temperature
R air distribution to the windscreen and front
side windows
R air-recirculation mode off
i If necessary, the "Cooling with dehumidifi-
cation" function is activated. In this case, the
indicator lamp above rocker switch
¿ remains switched off.
X To switch off: press rocker switch ¬up or
down.
The indicator lamp above rocker switch ¬
goes out. The previous settings are reactiva-
ted. Air-recirculation mode remains deactiva- ted. Demisting the windows
Windows misted up on the inside X
Activate the "Cooling with air dehumidifica-
tion" function with the ¿rocker switch.
X Switch on automatic mode using the Ã
rocker switch.
X If the windows continue to mist up, activate
the "Windscreen demisting" function using
the ¬ rocker switch. i
You should select this setting only until the
windscreen is clear again.
Windows misted up on the outside X
Switch on the windscreen wipers.
X Switch on automatic mode using the Ã
rocker switch.
i If you clean the windows regularly, they do
not mist up as quickly. Rear window heating
General notes The rear window heating has a high current
draw. You should therefore switch it off as soon
as the window is clear. It otherwise switches off
automatically after several minutes.
If the battery voltage is too low, the rear window heating may switch off.
Switching the sound on/off X
Turn the key to position 2in the ignition lock
(Y page 133).
X Press the ¤rocker switch up or down.
The indicator lamp above the ¤rocker
switch lights up or goes out.
Problems with the rear window heating Problem
Possible causes/consequences and
M MSolutions The rear window heating
has switched off prema-
turely or cannot be acti-
vated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heating
can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can also temporarily deactivate the flow of
fresh air manually if unpleasant odours are
entering the vehicle from outside. The air already inside the vehicle will then be recircula-
ted.
If you activate air-recirculation mode, the win-
dows can mist up more quickly, particularly at
low outside temperatures. Use air-recirculation
mode only briefly to prevent the windows from
misting up. Operating the climate control system

Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all the
way to the right. Otherwise, you could shift
unintentionally into 3rdor4th gear and dam-
age the transmission. If you shift down at too high a speed (trans-
mission braking), this can cause the engine to
overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients. There is otherwise a risk of damaging the clutch.
! On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift into gear 1, 2or3in good time.
This uses the engine's braking effect. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. k
