WARNING■The general information relating to the use of assistance systems must
be observed » page 127, 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 140 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.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the
Assis-tants
menu option » page 44.
Information messages
Read and observe
on page 140 first.
In MAXI DOT display the icon appears for a few seconds and the following
message.
Driver alert.
Take a break!
An audible signal is also emitted.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
141
The tyre pressure monitoring function (hereinafter referred to as the system)
monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light in the
instrument cluster lights up and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 38 .
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 176.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.

ator, radiator fan - danger to life!
■
Never touch the electric wiring on the ignition system.
■
Avoid short circuits in the electrical system, particularly on the vehicle's
battery.
■
Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts – risk to life! Always remove any jewellery,
tie back long hair and wear tight fitting clothing before completing any
work.
WARNINGInformation for working on the fuel system or the electrical system■Always disconnect the vehicle battery from the electrical system.■
Do not smoke.
■
Never work near open flames.
■
Always have a functioning fire extinguisher nearby.
165Inspecting and replenishing
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
Checking
Black colour - electrolyte level is correct.
Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced.
For technical reasons, the electrolyte level cannot be checked on vehicles with
the designation “AGM” .
Vehicles with the START STOPsystem are fitted with a battery control unit for
checking the energy level for 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.
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 172 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.
174General Maintenance
CAUTIONOn 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 189.
Replacing
Read and observe
and on page 172 first.
The new vehicle battery must have the same capacity, voltage, current and the
same 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.
Disconnecting and reconnecting
Read and observe
and on page 172 first.
Disconnecting
›
Switch off the ignition.
›
Disconnect the negative terminal first and then the positive
terminal of
the battery.
Connecting
›
Connect the positive terminal first, then the negative
battery terminal.
After disconnecting and re-connecting the vehicle battery, the following func-
tions or devices are partially or completely inoperative.
Function / deviceOperating measureElectrical power windows» page 61Panorama sliding/tilting roof» page 62Sun screen» page 63RadioEnter code » Owner's Manual
RadioTime settings» page 30CAUTION■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 172 first.
The vehicle's electrical system automatically prevents the battery from dis-
charging when the battery is being heavily used. 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.
CAUTION
■ Despite such intervention by the vehicle electric system management, the
vehicle battery may be drained. For example, when the ignition is switched on
a long time with the engine turned off or the side or parking lights are turned
on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle
battery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is
often not aware of it having taken place.175Inspecting and replenishing
Notes for driving with repaired tyresRead and observe
on page 187 first.
The inflation pressure of the repaired tyre must be checked after driving for 10minutes.
If the tyre inflation pressure is 1.3 bar or less
›
Do not continue to drive! You cannot properly seal with tyre with the
breakdown kit.
If the tyre inflation pressure is 1.3 bar or more
›
Set the tyre pressure to the correct value.
›
Continue driving carefully to the nearest specialist garage at a maximum
speed of 80 km/h (50 mph).
WARNING■ A tyre filled with sealant has the same driving characteristics as a stand-
ard tyre.■
Do not drive faster than 80 km/h (50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
Jump-starting
Introduction
This chapter contains information on the following subjects:
Jump-starting using the battery from another vehicle
189
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat.
WARNING■ Pay attention to the warning instructions relating to working in the en-
gine compartment » page 165.■
A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C. If the battery is frozen, do not carry out a jump start with the bat-
tery of another vehicle – risk of explosion!
■
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery – risk of explosion!
WARNING (Continued)■ Never jump-start vehicle batteries with an electrolyte level that is too low
– risk of explosion and caustic burns.■
The vent screws of the battery cells must be tightened firmly.
Note
We recommend you buy jump-start cables from a car battery specialist.

189Emergency equipment and self-help
›Attach the clamp 4 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. 188.
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.
