s at the top and pressing the bottom.
Range
The receiver is inside the vehicle. The remote
control, when fitted with new batteries, has a
range of several hundred metres. Obstacles
between the remote control and the vehicle,
bad weather conditions and discharged bat-
teries can considerably reduce the range of
the remote control. CAUTION
● The r a
dio frequency remote control con-
tains electronic components. Therefore, avoid
getting it wet and exposing it to knocks or di-
rect sunlight.
● The use of inappropriate batteries may
dam
age the radio frequency remote control.
For this reason, always replace the used bat-
tery with another of the same voltage, size
and specifications. For the sake of the environment
● Ple
ase dispose of your used batteries cor-
rectly and with respect for the environment.
● The remote control battery may contain
perc
hlorate. Observe the legal provisions re-
garding disposal.
● Care should be taken so as not to operate
the remot
e control unintentionally so as to
prevent the auxiliary heater being switched
on accidentally. Programming the auxiliary heater
Before pr
ogramming it, check that the vehi-

tioning controls. The duration is also used to cal-
culate the departure time for the manual air con-
ditioner. It can be set between 10 and 60 mi-
nutes at 10-minute intervals.
This returns to the main menu.
The programmed departure time determines
the ap
pr
oximate time it should take to reach
the temperature set in the vehicle. The start
of the heating operation is determined auto-
matically depending on the outside tempera-
ture.

Diesel engines can take a few seconds longer
than usual to start on cold days. Therefore
the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at
operating temperature, or at outside temper-
atures above +8°C, the warning lamp will light up for about one second. This means
that
the engine starts immediately.
If the engine does not immediately start up,
interrupt the starting process and try again
after 30 seconds. To start the engine again,
return the key to position 1 .

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

● 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
