The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on. In the start-stop mode, the engine automatically switches to the vehicle's idle phase, e.g. when stopped at traffic lights. The engine restarts automatically
where necessary.
The system can work only if the following basic conditions are met. The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
WARNING■ The brake servo unit and power steering only operate if the engine is run-
ning.■
Never let the vehicle roll with the engine switched off.
CAUTION
Always deactivate the START-STOP system before driving through wa-
ter » page 148 .Note■
If the driver's seat belt is removed for more than approx. 30 seconds or the driv-
er's door is opened during stop mode on vehicles with manual transmission or au- tomatic transmission (when the selector lever in position P), the engine must be
started manually » page 133.■
After manually starting the engine on vehicles with manual transmission, auto-
matic engine shut down is not possible until the vehicle has travelled the re-
quired minimum distance for START-STOP mode.
■
If, on vehicles with automatic transmission, the selector lever positions D, S or N
are selected after driving in reverse, the vehicle will first need to achieve a speed
of over 10 km/h before automatic engine shut down can take place again.
■
Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable temperature for proper operation of the START STOP system.
■
If Climatronic is running in automatic mode, the engine may not switch off auto-
matically under certain conditions.

and in Tiptronic mode.
When the selector lever is in position P, the engine remains shut down even after
you release the brake pedal. Start the engine by pressing the gas pedal or by moving the selector lever into a different mode and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
No automatic engine shutdown takes place when the vehicle is moving at low speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
Operating conditions of the system
First read and observe the introductory information and safety warn-ings
on page 159.
The START-STOP system is very complex. Some of the procedures are hard to check without servicing.
No engine shut down is carried out
Before each STOP phase, the system checks whether certain conditions have
been met. No engine shut down takes place in the following situations.
› The engine has not reached the minimum temperature for the START STOP
mode.
› The temperature inside the vehicle has not reached the temperature set in the
air-conditioning system.
› The external temperature is very low/high.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The parking aid/Park Assist is switched on.
› The charge state of the vehicle battery is too low.
› The stationary vehicle is on a steep slope or a steep downhill section.
› The idling speed is too high.
› The steering angle is too large (manoeuvring).
› The selector lever position
R is selected (e.g. when parking).
The warning symbol appears in the instrument cluster display.
The automatic start procedure takes place again
During the STOP phase, the engine fires up without any active driver intervention, e.g. in the following situations.
› The vehicle begins to roll, e.g. on a slope.
› The difference between the temperature setting of the air-conditioning system
and the inside temperature is too large.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The brake pedal was pressed several times (the pressure in the braking system
is too low).
› The charge state of the vehicle battery is too low.
› The current consumption is too high.

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
161
Information messages
161WARNING■ For the driving ability is always the driver's responsibility. Never drive if you
feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather conditions or poor road conditions).■
The fatigue detection system is designed primarily for motorway driving.
Function
First read and observe the introductory information and safety warn-ings
on page 161.
The fatigue detection system advises the driver on the basis of information about
the steering behaviour, to take a break from driving. The system recommends a
break at speeds of 65-200 km/h.
After the ignition has been switched on, the system evaluates the steering be-
haviour for 15 minutes. This baseline analysis is constantly compared with the
current steering behaviour.
If the system detects deviations from normal steering behaviour due to possible
fatigue of the driver, it recommends to take a break from driving.
The system deletes the stored baseline analysis if one of the following condi-
tions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the sys-
tem recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the Wizards
menu option » page 28.
Information messages
First read and observe the introductory information and safety warn-
ings
on page 161.
The symbol will appear in the MAXI DOT display for a few seconds, along with
the following message.
Fatigue detected. Take a break.
An audible signal is also emitted.

Checking the battery electrolyte level
Fig. 168
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 215.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 168, the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour - electrolyte level is correct.
› Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced.
Vehicles with a START-STOP system are fitted with a battery control unit for checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist ga-rage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
Winter time
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
CAUTION
For technical reasons, on vehicles with the description “AGM”, the electrolyte lev-
el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
First read and observe the introductory information and safety warn-ings
on page 215.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a “quick-charge”, disconnect both battery cables (first
“negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red = “posi-
tive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove themains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
217Inspecting and replenishing
It is not necessary to disconnect the cables of the battery if you recharge the ve-
hicle battery using low amperages (for example from a mini-charger). Refer to the
instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 236, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Replace
First read and observe the introductory information and safety warn-
ings
on page 215.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be
purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.
Disconnecting or reconnecting
First read and observe the introductory information and safety warn-ings
on page 215.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.

We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 215.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the
following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event of an emergency.
