Emergencies
If you choose to change the engine compart-
ment l
amp
s yourself, remember that it is a
dangerous area ››› in Work in the engine

ar

tment on page 262.
Always use identical bulbs with the same
designation. The name can be found on the
base of the bulb holder.
Depending on how equipped the vehicle is,
there are different sets of headlights and tail
lights:
● Halogen headlights
● Full-LED main headlights*
● Halogen headlights with LED daytime run-
ning lights*
● Re

ar bulb light
● LED rear light*
Ful
l-LED headlight system*
Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped
beam and route light) with light emitting di-
odes (LEDs) as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to
an authorised workshop to have it replaced. WARNING
● Tak e p

articular care when working on com-
ponents in the engine compartment if the en-
gine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The
glas
s can break when you touch the bulb,
causing injury.
● When changing bulbs, please take care not
to injure
yourself on sharp edges, in particu-
lar on the headlight housing. CAUTION
● Remo v

e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights and the parking light
before c
hanging a bulb.
● Take good care to avoid damaging any com-
ponents. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Ple a

se check at regular intervals that all
lighting (especially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users. ●
Bef or

e changing a bulb, make sure you
have the correct new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead, since the fingerprints left on the
glass will vaporise as a result of the heat gen-
erated by the bulb, they will be deposited on
the reflector and will impair its surface. 94

The rev counter indicates the number of en-
gine rev
o

lutions per minute ››› Fig. 120 1 .
Tog 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 ›››

● At outside temperatures above +4°C
(+39°F), even when the “ice c
rystal symbol”
is not visible, there may still be patches of ice
on the road.
● Do not rely on the outside temperature in-
dicator! Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and
instructions on the display may vary. In the
case of displays without warning or informa-
tion texts, faults are indicated exclusively by
the warning lamps.
● Depending on the equipment, some set-
tings
and instructions can also be carried out
in the Easy Connect system. ●

Safety

Operation
Normal temperature
If in norm
al
operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 266. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
›››  page 35 as a guide.
● Additional lights and other accessories in
front of
the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is moving. If the spoiler is damaged this can re-
duce the c
oo

ling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

very low, the lower diode flashes in red.
The yellow control lamp  lights up when the
reserve level has been reached.
The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode. The green warning lamp  switc

hes off when
the natural gas is exhausted. The engine
changes to operate with petrol.
Problem: If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard. WARNING
If the warning lamps and messages are ignor-
ed, the v ehic

le may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
mess
ages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al
low it to cool.
● In any vehicle, the engine compartment is a
hazar
dous area and could cause severe inju-
ries ››› page 262. CAUTION
