Star
t-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 excessive-
ly.
● The St
art-Stop System is manually deacti-
vated.
● The w
indscreen de-mist function is turned
on.
● The temperature of the interior exceeds the
comfor
t limits ( A/C button).
● If the airflow is increased by more than 3
pr e
s
ses.
● Temperature setting HI or LO is sel
ected.●
The engine coo
lant temperature is insuffi-
cient.
● The alternator is faulty, for example the V-
belt ha
s ruptured.
● If any of the conditions described in the
previou
s section are not fulfilled.
When the engine is turned off by the Start-
Stop function, this is displayed on the instru-
ment panel.
If the Start-Stop system is not switched on,
the warning lamp will appear on the instru-
ment panel. WARNING
Never allow the vehicle to move with the en-
gine off f or an
y reason. You could lose control
of your vehicle. This could cause an accident
and serious injury.
● The brake servo does not work with the en-
gine off. Y
ou need more force to stop the vehi-
cle.
● Power steering does not work when the en-
gine 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 wat
er (fording streams, etc.). Note
● For v
ehicles with the Start-Stop function
and a manual gearbox, when the engine is
started, the clutch must be pressed. ●
When the condition s
for the Start-Stop
function are not fulfilled, the instrument pan-
el displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than
270°, it wi
ll not be possible to start the vehi-
cle again. To start the vehicle, straighten the
steering wheel so that it is turned less than
270°.

Advice
fluids and consumables replaced by a Techni-
c al
Service. Please observe the relevant in-
structions ››› page 190. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.
g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coo
lant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● App
ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
page 52.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition! ●
Never c o
ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing 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:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. –
Never ac c
elerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
syst
em or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sud den
ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range.202
