Alternator

This warning lamp signals a fault in the alternator.
The warning lamp
 lights up when the ignition is switched on. It should go
out when the engine has started running.
If the warning lamp  lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest qualified
workshop.
You should avoid using electrical equipment that is not absolutely necessary
because this will drain the battery.
Tyre pressure

The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.The tyre monitor
13) compares wheel revolutions and with this information,
the diameter of each wheel using the ESP sensors. If the diameter of a wheel
changes, the tyre monitor indicator lights  . The wheel diameter changes
when:
•Tyre pressure is insufficient.•The tyre structure is damaged.•The vehicle is unbalanced because of a load.•The wheels of one axle are under more pressure (for example, driving with
a trailer or on extreme slopes).•The vehicle is fitted with snow chains.•The emergency wheel is fitted.

engines.•The battery charge must not be low for the next start.•The battery temperature must be between -1°C and 55°C.•The parking assistant, Park Assist* must not be activated.
Interrupting the Start-Stop function
In the following situations, the Start-Stop function will be interrupted and the
engine will automatically start:•The vehicle is moving.•The brake pedal is pressed several times in a row.•The battery has been discharged excessively.•The Start-Stop System has been manually deactivated.•The windscreen de-mist function is turned on.•The temperature of the passenger compartment exceeds the convenience
limits (button ⇒page 152, fig. 114 should be selected).•If in an increase in airflow ⇒page 152, fig. 114 is required for more
than three presses.•Either of the temperature settings, HI or LO, is selected.•The engine coolant temperature is insufficient.•The alternator is faulty, for example the V-belt has ruptured.•If any of the conditions described in the previous section are not fulfilled.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and serious
injury.•The brake servo does not work when the engine is not running. You
need more force to stop the vehicle.•Power assisted steering does not work when the engine is not running.
That is why it is much more difficult to turn the steering wheel.Note
•For vehicles with the Start-Stop function and a manual gearbox, when the
engine is started, the clutch must be pressed.•When the conditions for the Start-Stop function are not fulfilled, the dash
panel displays the Start-Stop indicator dimmed.•The vehicle can be restarted by rotating the steering wheel three times,
that is, more than 270°.

Driving and the environment191
Safety First
Controls and equipment
Practical tips
Technical Data
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum
service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not regularise until having
driven some four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases
tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use.
Saving electrical energy
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

Checking and refilling levels
216
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear stick to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 264. The battery could
explode.•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•Al wa ys m ake s u re yo u ha ve n o t l e f t a ny o bj e c t s , s u ch as cl e an i n g cl o t h s
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!
