WARNING
When inflating the wheel, the air compressor
and the inflat or t

● Protect hands and skin from hot parts.
● Do not place the hot flexible inflator tube or

essor on flammable material.
● Allow them to cool before storing the de-
vice.
● If
it is not possible to inflate the tyre to at

CAUTION
● To pr ev
ent damage to the engine, the rev
counter needle should only remain in the red
zone for a short period of time.
● When the engine is cold, avoid high revs
and heavy ac
celeration and do not make the
engine work hard. For the sake of the environment
Changing up a gear in time reduces fuel con-
sumption and noi se.Rev counter
The rev counter indicates the number of en-
gine r
ev
o
lutions per minute ›››
Fig. 110 1 .
T og
ether w
ith the gear-change indicator, the
rev counter offers you the possibility of using
the engine of your vehicle at a suitable
speed.
The start of the red zone on the dial indicates
the maximum engine speed which may be
used briefly when the engine is warm and af-
ter it has been run in properly. Before reach-
ing this range, you should change to a higher
gear for vehicles with a manual gearbox or for
automatic gearboxes put the selector lever in
“D” or take your foot off the accelerator ped-
al. We recommend that you avoid high revs and
that
you follow the recommendations on the
gear-change indicator. Consult the additional
information in ›››
page 25. CAUTION
Never allow the rev counter needle 1 ›››
Fig. 110 to g o int
o the red zone on the
scale for more than a very brief period, other-
wise there is a risk of engine damage. For the sake of the environment
Changing up a gear early will help you to save
fuel and minimi
se emissions and engine
noise. Indications on the display

Operation
● Immedi at
ely
after pushing the start-up but-
ton, keep the vehicle key next to the steering
column ››› Fig. 174.
● The ignition connects and the engine starts
automatic
ally.
Emergency disconnection
If the engine does not stop after briefly press-
ing the start-up button, an emergency dis-
connect will be required:
● Press the starter button twice within 1 sec-
ond or pres
s it once for more than 2 seconds
››› .
● The engine turns off automatically.
En gine r

start feature
If no valid key is detected inside the vehicle
after the engine stops, you will only have 5
seconds to restart it. A warning will display
on the dash panel screen.
After this interval, it will not be possible to
start the engine without a valid key inside
the vehicle. WARNING
Any accidental movement of the vehicle could
re s
ult in serious injury.
● When pressing the start-up button, do not
pre
ss the brake or clutch pedal, this way the
engine will start immediately. WARNING
If vehicle keys are used negligently or with-
out due c ar
e, this may cause accidents and
serious injury.
● Never leave any key inside the vehicle
when exitin
g. Otherwise, a child or unauthor-
ised person could lock the vehicle, start the
engine or connect the ignition and, in this
way, operate electronic equipment (e.g. the
windows). Note
In diesel vehicles with the Keyless Access

Brakes and brake servo sys-
tems Introduction WARNING
● The brak e ser
vo only works when the en-
gine is running. Braking when the engine is
switched off requires applying more strength
to the brake pedal. Risk of accident!
● Press down on the clutch pedal when stop-
ping and brak
ing with a manual gearbox,152

Driving
petrol engine vehicle at low speed. Other-
wi
se, the br
ake servo might not work proper-
ly. Risk of accident!
● In the event of damage to the standard
front s
poiler or where a different front spoil-
er, wheel trims, etc. are subsequently fitted,
make sure the air vent to the brakes on the
front wheels is not blocked. Otherwise, brak-
ing operations may be impaired. Risk of acci-
dent!
● Always fully release the handbrake. If it is
only p
artially released, this will cause over-
heating of the rear brakes, which can impair
the function of the brake system. Risk of acci-
dent!
● Never leave children unsupervised in the
vehicl
e. They could release the handbrake or
move the gear lever. The vehicle could start
moving. Risk of accident!
● Insufficient fuel can cause the engine to run
irregu
larly or to switch off. Brake assist sys-
tems could be impaired. Risk of accident!
● Always adjust your driving style to suit visi-
bility
, the weather and road and traffic condi-
tions. The best vehicle safety offered by
brake assist systems must never encourage
you to run greater risks. Risk of accident! CAUTION
● Ob ser
ve the information concerning new
brake pads ››› page 161.
● Where braking is not necessary, do not
wear do
wn the brake pads by pressing down gently on the brake pedal. This causes the
brak
e
s to overheat, increasing their wear and
increasing braking distances.
● To ensure the brake assist systems work
properly, a
ll wheels must be fitted with tyres
approved by the manufacturer. Note
● If y
ou brake suddenly and the brake system
control unit regards the situation as hazard-
ous for the drivers behind you, the brake
lights will begin to flash automatically. After
reducing speed to approximately 10 km/h (6
mph) or stopping the vehicle, the brake lights
will stop flashing and the hazard warning
lights will switch on. The hazard warning
lights are automatically switched off when
you accelerate or restart the vehicle.
● On long, steep gradients, reduce your
speed and ch
ange to a lower gear (manual
gearbox) or move the selector lever to a lower
gear position (automatic gearbox). This uses
the force of the engine and the brakes do not
suffer as much. If you still have to brake, do
so intermittently, pressing down repeatedly
on the brake pedal.
● Vehicle modifications (e.g. to the engine,
brake
s, frame or a combination of wheels and
tyres) could impair the brake assist systems
››› page 192, Accessories and modifications
to the vehicle .
● In the event of a fault in the ABS system,
the ESC, T
CS and EDL are switched off auto- matically. A fault in the ABS is indicated by
the

››› page 209 WARNING
● The fo l
lowing indications must be taken in-

stop the vehicle! Go to a technical service.
● A fault in the brake system or in the Anti-
lock br
ake system (ABS) can lead to longer
