Climatronic
If humidity increases in the vehicle, an automatic shutdown of air recirculation
can occur.
WARNINGThe recirculation system cannot be switched on for a longer period of time,
because no fresh air is fed through 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 windows mist up, turn on the re-
circulation system immediately - The is a risk of an accident!
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from the interior is deposited on the evapo-
rator of the air conditioner. This produces a permanent odour when the air
conditioning system is operating which can only be eliminated through consid-
erable effort and expense (replacement of compressor).Air outlet ventsFig. 113

START-STOPsystem
Introduction
This chapter contains information on the following subjects:
Operation
92
Manually deactivating/activating
93The START-STOP system (hereinafter only referred to as "system") reduces the
CO 2 emissions, as well as harmful emissions and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
The system function depends on many factors. Some of them must be met by
the driver, the others are related to the system and cannot be influenced nor
recognised.
For this reason, the system can react differently in situations which are iden-
tical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even if this was manually deactivated using the key ).
Note
If the engine was stopped by the system, the ignition remains on.
Operation

Display
Vehicles with manual transmission
The motor is automatically switched off as soon as the vehicle comes to a halt,
the shift lever is shifted to the neutral position and the clutch pedal is re-
leased.
The motor is automatically started as soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The motor is automatically switched off as soon as the vehicle comes to a
standstill and the brake pedal is actuated.
The motor is automatically started as soon as the brake pedal is released.
92Driving
Page 95 of 196

Conditions for the system function
The following conditions are required for the correct system function.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed exceeded 4 km/h after the last stop. No trailer or other accessory is connected to the trailer socket.
System status
The system status is shown on the display » Fig. 116 when stopped.
The engine is automatically switched off; when driving off again, the en-
gine is started automatically.
The motor is not automatically switched off.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air conditioning or heating output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en- gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
More information about the current system status can be displayed on the In-
fotainment screen » Owner's Manual Infotainment .
If there is a system fault , the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.
Note
■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted manually.■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

the automatic start process takes place.
Brakes and Parking
Introduction
This chapter contains information on the following subjects:
Handbrake
94
Parking
94
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between service intervals by a spe-
cialist garage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can 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
over »
.
93Starting-off and driving
Page 96 of 196

Before negotiating a long or steep gradient , reduce speed and shift down a
gear. As a result, the braking effect of the engine will be used, reducing the
load on the brakes. If, nevertheless, there is a need for additional braking, it
should be carried out at intervals.
Emergency braking warning - If it is necessary to brake hard, the system may
cause the brake lights to automatically flash, to alert the traffic behind.
New brake pads must first be““run in”” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
If the brake fluid level is too low, it can cause faults in the braking system ;
the warning light will light up in the instrument cluster » page 29
,
Braking
system . If the warning light does not light up, yet the stopping distance is per-
ceived to be longer than before, the driving style should be adapted in view of
the unknown cause of the problem, and braking kept to a minimum - seek the
help of a specialist garage without delay.
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.■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the functionality of the brake system may be impaired – risk of accident!
■
Do not depress the brake pedal, if there is no requirement to slow down.
This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear - The is a risk of an accident!
■
Only brake for the purpose of drying and cleaning the brake discs if the
traffic conditions permit this. Do not place any other road users in jeopardy.
■
Recommendations for new brake pads should be followed.
■
When stopping and parking, the parking brake should always be applied
firmly, otherwise the vehicle could move off - The is a 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 front brakes could be in danger of overheating – The is a
risk of an accident!
HandbrakeFig. 118
Handbrake
Read and observe on page 94 first.
The handbrake secures the vehicle against unwanted movement when stop-
ping and parking.
Apply
›
Pull the handbrake lever firmly upwards.
Undoing
›
Pull the handbrake lever up slightly while pushing in the locking button
» Fig. 118 .
›
Move the lever right down while pressing the lock button.
The handbrake warning light lights up when the handbrake is applied, provi-
ded the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied. The handbrake warning is activated if the vehicle is driven
at a speed of over 5 km/h for more than 3 seconds.
WARNINGDisengage the handbrake completely. A handbrake which is only partially
disengaged can result in the rear brakes overheating. This can have a nega-
tive effect on the operation of the brake system – risk of accident!
