Instruments and warning/control lamps
Vehicles with an automatic gearbox*
The display is only visible in tiptronic mode ⇒ page 159
The following display symbols mean:
●  Shifting up a gear
●  Shifting down a gear
CAUTION
The gear-change indicator is intended to help save fuel. It is not intended to
recommend the right gear for all driving situations. In certain situations, on-
ly the driver can choose the correct gear (for instance when overtaking, driv-
ing up a steep gradient or towing a trailer).
Note
The display disappears from the instrument panel when you press the
clutch pedal. 
Control lamps Control and warning lamps
The control and warning lamps are indicators of warnings, ⇒ , faults ⇒ or certain functions. Some control and warning lamps come on when the ig-
nition is switched on, and switch off when the engine starts running, or
while driving.
Depending on the model, additional text messages may be viewed on the
instrument panel display. These may be purely informative or they may be
advising of the need for action ⇒ page 61, Instruments. Depending upon the equipment fitted in the vehicle, instead of a warning
lamp, sometimes a symbol may be displayed on the instrument panel.
When certain control and warning lamps are lit, an audible warning is also
heard.

WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from the traffic, ensuring that there are no easi-
ly inflammable materials under the vehicle which could come into contact
with the exhaust system (e.g. dry grass, fuel).
● A faulty vehicle represents a risk of accident for the driver and for oth-
er road users. If necessary, switch on the hazard warning lamps and put
out the warning triangle to advise other drivers. 

Lights Introduction
The legal requirements regarding the use of vehicle lights in each country
must be observed.
The driver is personally responsible for the correct use and adjustment of
the lights in all situations.
Additional information and warnings:
● Information system ⇒ page 73
● Changing bulbs ⇒ page 252
WARNING
If the headlights are regulated too high and the main beam is not used
correctly, there is a risk of dazzling or distracting other road users. This
could result in a serious accident.
● Always make sure that the headlights are correctly adjusted.
● Never use the main beam or headlight flasher when it can dazzle oth-
er drivers.

(trailer turn signals) and the vehicle turn signal will flash at double speed.
● The main beam headlights can only be switched on if the dipped beam
headlights are already on. 

Lighting of the instrument panel and controls*
Depending on the model, lighting of the instrument panel and controls can
be adjusted in the Easy Connect system, using the button 
and the func-
tion button SETUP ⇒ page 81.
Headlight range control
The headlight range control ⇒ Fig. 62 is modified according to the value of
the headlight beam and the vehicle load status. This offers the driver opti-
mum visibility and the headlights do not dazzle oncoming drivers ⇒ 
.
The headlights can only be adjusted when the dipped beam is switched on.
To reset, turn switch ⇒ Fig. 62:

and minimum drawbar load
3Driver only, luggage compartment full With trailer and
maximum drawbar load

If the vehicle load does not correspond to those shown in the table, it is possible to select
intermediary positions.
Dynamic headlight range control
The control is not mounted in vehicles with dynamic headlight range con-
trol. The headlight range is automatically adjusted according to the vehicle
load status when the headlights are switched on.
Instrument panel lighting
In vehicles with the daytime driving light, the instrument panel lighting
switches on in dark conditions (for example, when passing through a tun-
nel). This reminds the driver to manually switch on the dipped beam, so
that the vehicle rear lights also switch on ⇒ page 109.
WARNING
Heavy objects in the vehicle may mean that the headlights dazzle and
distract other drivers. This could result in a serious accident.
● Adjust the light beam to the vehicle load status so that it does not
blind other drivers.


150Driving
Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fastened.
● The bonnet must be closed.
● The vehicle must have travelled at more than 4 km/h (2 mph) since the
last stop.
● The vehicle cannot be towing a trailer.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.
● To avoid injury, make sure that the Start-Stop system is switched off
when working in the engine compartment ⇒ page 152.
CAUTION
The Start-Stop system must always be switched off when driving through
flooded areas ⇒ page 152. Stop/Start the engine
Vehicles with a manual gearbox
–
When the vehicle is stopped, put it into neutral and release the
clutch pedal. The engine will switch off. The warning lamp 
will appear on the instrument panel display.
– When the clutch pedal is pressed the engine will start up again.
The warning lamp will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a stop and keep the
brake pedal pressed down with your foot. The engine will switch
off. The warning lamp  will appear in the display.
– When you take your foot off the brake pedal the engine will start
up again. The warning lamp will switch off.
Additional information related to the automatic gearbox
The engine stops when the selector lever is in the positions P, D, N and S, in
addition to when in manual mode. With the selector lever in position P, the
engine will also remain switched off when you take your foot off the brake
pedal. In order to start the engine up again the accelerator must be press-
ed, or another gear engaged or the brake released.
If the selector lever is placed in position R during the stopping phase, the
engine will start up again.
Change from position D to P to prevent the engine from accidentally starting
when changing and passing by position R. 
