•It will start flashing to indicate that ESP is counteracting an unstable
driving condition.•It lights up when the ignition is switched on for approx. 2 seconds while
the function is checked.•The warning lamp will light up if there is a malfunction in the ESP.•It will light up after the battery has been disconnected.•The warning lamp will light up if the ESP is switched off.•It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp lights up and stays on after the engine is started, this
may mean that the control system has temporarily switched off the ESP. In this
case the ESP can be reactivated by switching the ignition off and then on
again. After this the warning lamp should go out to show that the system is
fully functional.
The warning lamp will light up when the ignition is switched on if the battery
has been disconnected and then reconnected. It should go out again after
driving a short distance if the steering wheel is turned slightly.
For further information on the ESP, see ⇒page 187.Alternator
F
The warning lamp signals a fault in the alternator or in the
vehicle’s electrical system.The warning lamp
F lights up when the ignition is switched on. It should
switch off after the engine has started.
If the warning lamp F lights up when you are driving, you can normally
continue as far as the nearest qualified workshop. However, given that the
battery will be running down, any electrical consumption not absolutely vital
should be switched off.
Caution
If the coolant warning lamp

alternator waning lamp while driving ⇒page 78, stop the vehicle immedi-
ately and switch off the engine. In this case the coolant pump is no longer
working, and there is a risk of engine damage.
Main beam headlights
The indicator lamp
lights up when the main beams are on or when the
headlight flasher is operated.
For further information on the main beam headlights, see ⇒page 122.
Engine management
% 0 #
This warning lamp monitors the engine management system
for petrol engines.The warning lamp
% 0 # (Electronic Power Control) lights up while the function
is being checked.
Note
If the warning lamp lights up while the vehicle is moving, this indicates a fault
in the engine management system. The vehicle must be taken immediately to
a qualified workshop to have the engine serviced.

78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.
Fault in the cooling system
Faults in the cooling system must be repaired immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 229.
– Add more coolant if necessary ⇒page 229.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
v has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
E
If the engine oil pressure is too low the fault must be repaired
immediately.If the
E
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 226.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 227.
Engine oil level correct
If the
E symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on! Do not continue to run the engine, even at
idle speed .

Driving and the environment195
Safety First
Operating Instructions
Practical Tips
Technical Specifications
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 - 40seconds 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 normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible. Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase 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 year round as they increase fuel consumption 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 rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120km/h your vehicle will use about
12% m ore fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
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 components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h
Checking and refilling levels
224
WARNING
Never open the bonnet if you see steam or drips of coolant being released
from th e eng ine compar t ment . Fail ure to comp ly could resul t in bur ns. Wait
until no steam or coolant can be seen before opening the bonnet.Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment.Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below and
follow all general safety precautions. The engine compartment of the vehicle
is a potentially hazardous area ⇒
WARNING
•Switch the engine off.•Remove the ignition key.•Apply the handbrake firmly.•If your vehicle is equipped with a manual gearbox, place the gear lever
in neutral. If you are driving an automatic vehicle, place the selector lever
in position P.•Wait for the engine to cool down.•Children should not be allowed to approach the engine compartment.•Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. coolant).•Take care not to cause short circuits in the electrical system, especially
when working on the battery.
•Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.•Never open the expansion tank when the engine is hot. The cooling
system is under pressure.•Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the
expansion tank.•If any tests have to be performed with the engine running, there is an
added safety risk from the rotating parts (e.g. drive belts, alternator, radi-
ator fan, etc.) and from the high-voltage ignition system.•Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames.
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cause serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
