Operation
6. Use the warning triangle to draw the atten- tion of other r
oad users to your vehicle.
7. Always take the vehicle key with you when you l
eave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps
and the turn signal lamp in the switch will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn the vehicles driving be-
hind. If you continue braking, the hazard
warning lights will come on automatically
when the vehicle comes to a standstill. They
switch off automatically when the vehicle
starts to move again. WARNING
● The ri sk
of an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Due to the high temperatures that the cata-
lytic c
onverter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
a
l
s, for example dry grass or spilt petrol. This
could start a fire. Note
● The b att
ery will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
sc
ribed here is subject to the relevant statu-
tory requirements. Parking lights
When the parking light is switched on, (right
or l
ef
t turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
sw
it
ch in position , when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially. Motorway light* The motorway light is available on vehicles
equip
ped w
ith full-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when goin
g above 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when r educ
ing the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide of the road on which
you are driving is lit more intensely.
When a car that is manufactured in a country
that drives on the right travels to a country
that drives on the left (or vice versa), it is nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied with for
designated points of the light distribution.
This is known as “Tourist light”.

Operation
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

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
