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 special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery.
Worn brake pads
If the symbol lights up, have the front brake pads (and, for safety rea-
sons, the rear pads as well) inspected by a specialised workshop. Tyre pressure
The tyre pressure control system controls the tyre speed and
the frequency spectrum of each tyre.

The tyre control lamp 1)
compares wheel revolutions and with it, the wheel
diameter of each wheel using the ESC. If the diameter of a wheel changes,
the tyre control lamp lights up. 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 temporary spare wheel is fitted.
● The wheel on one axle is changed.

172Driving
–The instrument panel screen displays information about the sta-
tus of the Start-Stop function ⇒ Fig. 138.
Start-Stop function conditions
● The driver seat belt must be buckled.
● The bonnet must be closed.
● The engine must be at operating temperature.
● The steering wheel must not be turned more than 270°.
● The vehicle must not be on a steep gradient.
● The vehicle must not be in reverse.
● A trailer must not be connected.
● The temperature of the passenger compartment must be within the com-
fort limits (button AC
11 ⇒ Fig. 132 should be selected).
● The windscreen de-mist function must be off.
● If not, it requires an increase in airflow 10
⇒ Fig. 132 for more than three
presses.
● The temperature must not be set to HI or LO.
● The driver door must be closed.
● The diesel particulate filter must not be in regeneration mode, for diesel
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 aid system (Park Assist*) must not be activated.
Start-Stop function interruption
In the following situations, the Start-Stop function will be interrupted and
the engine will automatically start:
● The vehicle starts moving.
● The brake pedal is pressed several times in a row.
● The battery has been discharged excessively.
● The Start-Stop System is manually deactivated. ●
The windscreen de-mist function is turned on.
● The temperature of the passenger compartment exceeds the comfort
limits (button AC
11 ⇒ Fig. 132 should be selected).
● If in an increase in airflow 10 ⇒ Fig. 132 is required for more than three
presses.
● Temperature setting 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 fulfil-
led.
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 seri-
ous injury.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Turn off the Start-Stop system when driving through water (fording
streams, etc.).
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 in-
strument panel displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than 270°, Stop will not function;
however, the angle of steering wheel turn does not affect starting the vehi-
cle.
198Driving and the environment
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 61.
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 lev-
el 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 long time to warm up when it is idling. 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 maxi-
mum 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 exhaust gases, the
engine and the exhaust gas filtration systems should reach the optimum
operating temperature.
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 (2.5 miles). 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 one 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
Given that every kilo of extra weight will increase the fuel consumption, it is
advisable to always check the luggage compartment to make sure that no
unnecessary 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 100-120 km/h (60-75 mph) your vehicle
will use about 12% more 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, al-
ways 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*.

Checking and refilling levels
WARNING (Continued)
● 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 coolant expansion tank when the en-
gine 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.
● Always make sure you have not left any objects, such as cleaning
cloths 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 trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery from the on-board network. The ve-
hicle must be unlocked when this is done, otherwise the alarm will be
triggered.
– Do not smoke.WARNING (Continued)
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop.
