is not running, the gearbox oil pump does
not w
ork
and the gearbox is not adequately
lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a break-
down truck, it must only be suspended at the
front wheels. Reason: the drive shafts are lo-
cated on the front wheels. If the car is towed
with the rear wheels lifted off the road (I.e.
travelling backwards), the drive shafts also
turn backwards. The planetary gears in the
automatic gearbox then turn at such high
speeds that the gearbox will be severely
damaged in a short time. Note
● If it i

s not possible to tow the vehicle in the
normal way, or if it has to be towed further
than 50 km (30 miles), it must be transported
on a special car transporter or trailer.
● Should the power supply to the selector
lever be int
errupted in position P, the selector
lever will be locked. Before the vehicle can be
recovered/manoeuvred you must manually
release the selector lever ›››

F u

s
Introduction In general, a fuse can be assigned to various
electric
al

components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr

ent circuit without fuses can
cause a fire and serious injury. ●
Never u se a f

use with a higher value. Only
replace fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or simil
ar. CAUTION
● To pr ev

ent damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse,
you could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse.
● Several components may run on a single
fuse. 101

Emergencies
If you choose to change the engine compart-
ment l
amp
s yourself, remember that it is a
dangerous area ››› in Working in the en-
gine c omp
ar

tment on page 270.
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.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds than
that of the car. If an LED light fails, go to an
authorised workshop for its replacement. 104

Operation
For vehicles with no coolant temperature
g aug
e, a c
ontrol lamp  appears for high
coolant temperatures ››› page 274. Please
note ››› .
The c oo
l

ant temperature gauge only works
when the ignition is switched on ››› Fig. 124.
In order to avoid engine damage, please read
the following notes for the different tempera-
ture ranges.
Engine cold
If only the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal 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
temperat

ure is excessive ››› page 274. 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 43 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 cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Petrol/Diesel

e The display
››
› Fig. 125
only works when the
ignition is switched on. When the display rea-
ches the reserve mark, the lower diode lights
up in red and the control lamp  appears
››› page 114. When the fuel level is very low,
the lower diode flashes in red.
The fuel range is displayed on the instrument
panel ››› Fig. 122 3 .
The c ap
ac

ity of the fuel tank of your vehicle is
given in the Technical data section
›››  page 58. CAUTION
Never run the fuel tank completely dry. An ir-
re gu

lar fuel supply could cause misfiring. In
this way the unburned fuel can reach the ex-
haust system, which could cause the catalytic
converter to overheat resulting in damage. 118
