The fatigue detection system (following known as system) recommends the
driver taking a break from driving when, because of the driver's steering be-
haviour, driver fatigue can be detected.
WARNING■ Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
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 condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 182 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
The system evaluates steering behaviour and recommends a break at speeds
of 65-200 km / h.
The system detects a break from driving when 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
system recommends a driving break again after 15 minutes.
The system can be activated or deactivated in the Infotainment » Owner´s
Manual Infotainment , chapter CAR - vehicle settings .

WARNING■The use of open flames and light should be avoided.■Smoking and radio triggering activities should be avoided.■
Never use a damaged vehicle battery – risk of explosion!
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!
■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with an electrolyte level that is too low
– risk of explosion and caustic burns.
CAUTION
■ Improper handling of the vehicle battery may cause damage.■Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.■
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. Prevent the battery from discharging by disconnecting the battery's
negative terminal
or continuously charging the battery with a very low
charging current.
■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.
■
If the vehicle is frequently used for making short trips, the vehicle battery
will not have time to charge up sufficiently and may discharge.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.
Opening the cover
Fig. 233
Polyester cover of vehicle bat-
tery
Read and observe and on page 213 first.
The battery is located in the engine compartment. For some equipment var- iants, it is located underneath a polyester cover » Fig. 233.
›
Fold out the cover on the battery in the direction of the arrow.
The battery cover is installed in reverse order.
Checking the battery electrolyte level
Fig. 234
Vehicle battery: Electrolyte level
indicator
Read and observe and on page 213 first.
On vehicles with a vehicle battery fitted with a colour indicator, the electrolyte
level can be determined by looking at the change in colour of this display.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
Check
Black colour - electrolyte level is correct.
Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced.
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Vehicles with the START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine starts.
We recommend that you have the acid level checked regularly by a specialist
garage, especially in the following cases. ▶ High external temperatures.
▶ Longer day trips.
▶ After each charge.
214General Maintenance
Winter time
The vehicle battery only has a proportion of the starting power in lower tem-
peratures. A discharged vehicle battery may already freeze at temperatures
just below 0 °C .
We therefore recommend that you have the battery checked and, if necessary,
recharged by a specialist garage before the start of the winter.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
Read and observe
and on page 213 first.
A properly charged vehicle battery is essential for reliably starting the engine.A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, 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 the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, 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 low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical consumers and disconnect the negative
terminal
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START / STOP system or additional heating (auxiliary
heating), do not connect the pole terminal of the charger directly to the nega-
tive terminal of the vehicle battery but only to the engine earth » page 230.
Replacing
Read and observe
and on page 213 first.
The new vehicle battery must have the same capacity, voltage, current and thesame size as the original Battery. Suitable vehicle battery types can be pur-
chased from a specialist garage.
We recommend you have the battery replaced by a specialist garage.

to a solid metal part which is connected firmly to the en-
gine block or to the engine block itself.
The jump-start cable must be connected to the engine earthing point only on
vehicles with the START-STOP system » Fig. 250.
Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Start the engine of the vehicle with the discharged battery.
›
If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for 30 seconds before repeating the process.
›
Remove the jump start cables in the reverse order as attachment.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be significantly less than the capacity of
the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and
insulated terminal clamps. Observe the instructions of the jumper lead manu-
facturer.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black.
WARNING■
Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being star-
ted.■
The non-insulated parts of the terminal clamps must never touch each
other – risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– risk of short circuit!
■
Route the jump-start cables so that they cannot be caught by any rotat-
ing parts in the engine compartment.
