Sunroof*
Introduction The sunroof consists of two glass parts. The
r
e
ar part is fixed and cannot be opened. It al-
so has a sun blind. WARNING
If the sunroof is used negligently or without
p a
ying due attention, it can cause serious in-
jury.
● Open or close the sunroof and the sun blind
only
when no one is in their path of move-
ment.
● Never leave any key inside the vehicle
when ex
iting.
● Never leave a child or any other person who
ma
y need help in the vehicle, especially if
they have access to the vehicle key. If using
they key unattended, they could lock the ve-
hicle, start the engine, switch on the ignition
and activate the sunroof.
● After switching off, it is still possible to
open or clo
se the sunroof during a short space of time provided that neither the driver
nor p
a
ssenger door is opened. CAUTION
● To pr
event damage, during winter tempera-
tures remove any ice or snow that might be
on the car roof before opening the sunroof or
adjusting the tilt position.
● Before leaving the vehicle or in case of rain-
fa
ll, always close the sunroof. With the sun-
roof open or in a tilted position, water can en-
ter the interior and can cause considerable
damage to the electrical system. As a result,
other damage can occur in the vehicle. Note
● Le
aves and other loose objects that accu-
mulate on the sunroof rails should be regular-
ly cleaned away either by hand or with a vac-
uum.
● If the sunroof does not work correctly, the
anti-trap f
unction will not work either. Con-
tact a specialised workshop.
● Some settings can be saved in user ac-
cou
nts of the personalisation function

Air conditioning
Auxiliary heater (additional
he at
er)
Introduction The auxiliary heater runs on fuel from the ve-
hic
l
e's tank and can be used while you are
driving and when the vehicle is stationary.
The auxiliary heater can be switched on using
the fast heating button of the air condition-
ing controls, with the remote control or by
previously programming a departure time in
the auxiliary heater menu of the infotainment
system.
In winter, with the auxiliary heater switched
on, you can defog the windscreen and leave
it free of ice and snow (if it is a thin layer) be-
fore you start driving.
If the outside temperature is very high, the
vehicle interior can be ventilated with the en-
gine off using the auxiliary heater. WARNING
Swallowing a battery with a 20 mm diameter
or an y
other button battery can cause serious
and even fatal injuries within a very short
time.
● Always keep the remote control, keyrings
with b
atteries, the spare batteries, button
batteries and all other batteries over 20 mm
out of reach of children. ●
If
you suspect that someone may have
swallowed a battery, seek immediate medical
attention. WARNING
The auxiliary heater exhaust fumes contain
c arbon mono
xide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death.
● Never switch on the auxiliary heater or
le
ave it running in enclosed spaces or areas
with no ventilation.
● Never programme the auxiliary heater so
that
it switches itself on and is running in an
enclosed space or an area with no ventila-
tion. WARNING
The components of the auxiliary heater are
e xtr
emely hot and could cause a fire.
● Always park your vehicle so that no part of
the exh
aust system can come in contact with
easily flammable materials that might be be-
low the vehicle, such as dried grass. CAUTION
Never place food, medicines or other temper-
at ur
e-sensitive objects close to the air vents.
Food, medicines and other objects sensitive
to heat or cold may be damaged or made un- suitable for use by the air coming from the
v
ent
s. Note
After switching the engine on with a 12-volt
b att
ery that is heavily discharged or newly
changed or after a jump start some system
settings (such as the time, the date, the per-
sonalised comfort settings and the program-
ming) might be altered or deleted. Check and
correct these settings once the battery is suf-
ficiently charged. Switching on and off the auxiliary

WARNING
● Nev er ru
n the engine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
e xtr
eme load conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
shou l
d drive off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it
is difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both s ide
s to release the steering lock.
● When starting from cold, the engine may be
a little noi
sy for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
rec
onnected, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up .
● V
ehicles with automatic gearbox: after
swit
ching off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
l
ect
or lever is locked. Switching off the engine with the key

Possible vehicle theft is prevented with the
steering lock engaged. WARNING
● Nev er sw
itch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered 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. ●
Nev er r
emove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
le
ave the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
lo a
d for a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● Af t
er the engine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation.
● If the vehicle is stopped and the Start-Stop
sys
tem* switches off the engine, the ignition 166

approx. 1 minute before trying again. If neces-
sary, perform an emergency start ››› page 167.
5.Disconnect the electronic parking brake when
you are about to start driving ››› page 170. WARNING
Never leave the vehicle with the engine run-
nin g, e
specially if a gear or gear range is en-
gaged. The vehicle could then suddenly move
or something strange could happen that
would cause damage, fire or serious injury. WARNING
Cold start sprays could explode or cause a
s ud
den increase in the engine speed.
● Never use sprays to cold start the engine. CAUTION
● The s t
arter motor or the engine may be
damaged if you try to start the engine while

the catalytic converter and damage it. Note
● Do not w
ait until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions. 168
Driving
● To s
top the braking process, release the
button or press the accelerator. WARNING
The improper use of the electronic parking
br ak
e can cause accidents and serious injury.
● Never use the electronic parking brake to
st
op the vehicle, unless it is an emergency.
Braking distances can be considerably lon-
ger, since, under certain circumstances, only
the rear wheels brake. Always use the foot
brake.
● Never accelerate from the engine when a
ge
ar range or a gear is engaged and the en-
gine is running. The vehicle could move, even
if the electronic parking brake is activated. CAUTION
To prevent the vehicle from unintentionally
mo v
ing when parking it, first apply the elec-
tronic parking brake and then remove your
foot from the brake pedal. Note
● In v
ehicles with a manual gearbox, releas-
ing the clutch and accelerating at the same
time automatically disconnects the electronic
parking brake.
● If the vehicle battery is flat, it will not be
pos
sible to disconnect the electronic parking
brake. Use the jump-start ›››
page 58. ●
When the el ectr
onic parking brake is ap-
plied or released, noises may be heard.
● The system performs automatic and audi-
bl
e tests sporadically in the parked vehicle if
some time elapses without the electronic
parking brake being used. Parking
The electronic parking brake should always
be ap
p
lied when the vehicle is parked.
Always note the following points when park-
ing the vehicle: – Use the brake pedal to stop the vehicle.
– Apply the electronic parking brake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition.
Turn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle.
Addition
al notes on parking the vehicle on
gradients:
Turn the steering wheel so that the vehicle
rolls against the kerb if it started to roll.
● If the vehicle is parked facing downhi
ll,
turn the front wheels so that they point to-
wards the kerb . ●
If the
vehicle is parked facing uphill, turn
the front wheels so that they point away from
the kerb.
● Secure the vehicle as usual by applying the
electr
onic parking brake firmly and putting it
in 1st gear. WARNING
● Tak
e measures to reduce the risk of injury
when you leave your vehicle unattended.
● Never park where the hot exhaust system
cou
ld ignite inflammable materials, such as
dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in
the v
ehicle when it is locked. They would be
unable to open the vehicle from the inside,
and could become trapped in the vehicle in
an emergency. In the event of an emergency,
locked doors will delay assistance to vehicle
occupants.
● Never leave children alone in the vehicle.
They c
ould set the vehicle in motion, for ex-
ample, by releasing the electronic parking
brake or the gearshift lever, which would
cause the vehicle to move, but uncontrolla-
bly.
● Depending on weather conditions, it may
become e
xtremely hot or cold inside the vehi-
cle. This can be fatal. 171

● If it is necessary to work in the engine com-
par
tment while the engine is running, the ro-
tating components (for example, poly-V belt, alternator, radiator fan) and the high voltage
ignition sy
s
tem are an additional hazard.
● Observe the following additional warnings
if w
ork on the fuel system or the electrical
system is necessary:
– Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
