Operating modes
Automatic mode works in three modes - moderate, medium, and intensive.
Setting of the different modes takes place via the functional surface D
» Fig. 150 on page 116 or » Fig. 151 on page 116 .
After the automatic mode is switched on, Climatronic works in the last selec-
ted mode. The currently selected mode is displayed in the Infotainment dis-
play.
Air distribution control
Read and observe
on page 114 first.
The recirculation mode prevents contaminated outside air getting into the In-terior of the vehicle. In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.

Heating and manual air conditioning system
If the air distribution control is set to position when the recirculation modes
is switched on, the recirculated-air mode is switched off. By pressing the
button, the air recirculation also in this position can be switched on again.
When the cooling system ( button) is switched on and the temperature reg-
ulator is “turned” to the left, the recirculated-air mode is switched on.
Climatronic
The Climatronic can have a sensor that measures the air recirculation mode
and automatically turns on if there is an increased concentration of pollutants
in the incoming air.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
Automatically switching the air recirculation function on/off can be adjusted by pressing the button on the Climatronic and by subsequently pressing the
function surfaces
→
automatic air recirculation
in the Infotainment screen. Au-
tomatic switching on / off works at a temperature above 2 ° C.
A shut-off of the air recirculation function takes place automatically by press-
ing the button, possibly depending on the moisture conditions in the vehi-
cle interior.
WARNINGThe air recirculation cannot be switched on for a longer period of time be-
cause there is no supply of fresh air from the outside. “Stale air” may result
in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. As soon as the windows mist up, turn the air
recirculation mode off immediately - there is a risk of accident!
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).

Brakes and Parking
Introduction
This chapter contains information on the following subjects:
Electric parking brake

The wear of the brake pads is dependent on the operating conditions and driv-
ing style. Under difficult conditions (e.g. urban, sporty driving style) the condi-
tion of the brakes should also be checked by a specialist garage between the
service intervals.
The performance of the brakes can be delayed if the brakes are damp, iced up
in winter or if covered in a layer of salt . The brakes are cleaned and dried by
applying the brakes several times »
.
Corrosion on the brake discs and dirt on the brake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned by applying the brakes several times »
.
Before travelling a long distance with a steep gradient , reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. If you do have to brake, this should
be carried out at intervals.
Emergency braking display - when an emergency braking is performed, the
automatic flashing of the brake lights are used to alert the traffic behind.
New brake pads must first be “worn in” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
A too low brake fluid level can cause faults in the braking system , the warn-
ing light illuminates in the instrument cluster
» page 35,
Brake system
. If
the warning light does not illuminate and an extended stopping distance is re-
quired, then driving should be adapted according to the unknown cause of
fault and restricted braking effect - seek the assistance of a specialist garage
immediately.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
Do not press the brake pedal if braking is now required. This causes the
brakes to overheat and can also result in a longer braking distance and ex-
cessive wear - risk of accident!
■
Braking for the purpose of drying and cleaning the brake discs should be
carried out only if the traffic conditions permit. Do not place any other road
users in jeopardy.
■
Recommendations for new brake pads have to be observed.
■
When stopping and parking, the parking brake should always be on, oth-
erwise the vehicle could move off - there is the risk of an accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
Otherwise, the functionality of the brake system may be impaired – risk of
accident!

.
›
Pull the
button in the direction of arrow
1
and » Fig. 256 hold (you hear
an audible signal), the vehicle starts to brake strongly.
The braking process is interrupted when the key is released or the accelerator
pedal is actuated.
WARNING■ The emergency brake is to be used only in an emergency when the vehi-
cle cannot be stopped with the brake pedal.■
Do not place any objects in the recessed grip for the finger in front of the
parking brake key - the parking brake button could be blocked!
Note
■ If the vehicle battery is discharged, it is not possible to release the parking
brake. First connect the vehicle first to a power source, such as the battery of
another vehicle » page 287, Jump-starting and then turn off the parking
brake.■
Noise when switching on and off the parking brake is normal and therefore
harmless.
Auto Hold function
Fig. 257
The Auto-Hold function button
Read and observe on page 203 first.
The Auto Hold function (hereinafter referred to only as system) prevents the
vehicle from rolling unintentionally when stopped. It is, for example, not nec-
essary to secure the vehicle with the brake pedal or parking brake at traffic
lights.
204Driving
For the activation, deactivation and correct functioning of the system, the
following basic conditions are required.
The driver's door is closed.
The engine is running (or has been switched off automatically by the
START-STOP system).
On vehicles with automatic transmission the selector lever is not in mode
N (in this mode, the system is not available).
Stopping and starting
When stopping the system prevents the vehicle from rolling away. The warn-
ing light
illuminates in the instrument cluster. The brake pedal can be re-
leased.
