rest is also heated in some versions.
Switch off seat heating if there is nobody in
the seat.

Inappropriate use of the seat functions can
cau se sev
ere injuries.
● Assume the proper sitting position before
your trip and rem
ain in it throughout. This al-
so applies to the other occupants.
● Only adjust the seat position memory when
the vehic
le is stationary.
● Only switch the lumbar massage function
on and off when the v
ehicle is stationary.
● Keep hands, fingers, feet and other limbs
awa
y from the seat operating and adjustment
radius. WARNING
People whose pain and temperature thresh-
ol d h
as been affected by some kind of medi-
cine, paraplegia or chronic illness (e.g. diabe-
tes) may sustain burns to the back, buttocks
and legs from using the seat heaters that
may lead to a long healing process or that
may never completely heal. Seek medical ad-
vice if you have doubts regarding your health.
● People with limited pain and temperature
thresho
lds must never use seat heating. CAUTION
● To av oid d
amaging the heating elements of
the seat heaters, please do not kneel on the
seat or apply sharp pressure to a single point
on the seat cushion or backrest.
● Liquids, sharp objects and insulating mate-
rial
s on the seat could damage the seat heat-
ing.
● In the event of smells, switch off the seat
heating immedi
ately and have the unit in-
spected by a specialised workshop. For the sake of the environment
The seat heating should remain on only when
needed. Otherw i
se, it is an unnecessary fuel
waste. Lumbar massage function*

WARNING
The auxiliary heater fumes contain carbon di-

Carbon monoxide can cause people to lose
consciousness. It can also cause death.
● Never switch on the auxiliary heater or

unventilated.
● Never program the independent heating
syst
em to be activated and operated in
closed, unventilated areas. WARNING
The components of the auxiliary heater ex-

cause a fire.
● Always park your vehicle so that no part of
the exhau

flammable materials (such as dried grass). CAUTION
Never place food, medicines or other heat-

Replacing the remote control battery
If the light ›››
Fig. 197 B on the remote con-
tr o
l
does not come on when the button is
pressed, the remote control battery should
soon be replaced.
The battery is located beneath a cover on the
back of the remote control. Turn the slot to
the left using a flat, blunt object (e.g. a coin).
When changing the battery, use another bat-
tery of the same model and observe the po-
larity when fitting it ››› .
R an
g
e
The receiver is in the interior of the vehicle.
The remote control, when fitted with new bat-
teries, has a range of several hundred me-
tres. Obstacles between the remote control
and the vehicle, bad weather conditions and
discharged batteries can considerably reduce
the range of the remote control. An optimum range is obtained by keeping
the remote c
ontrol vertical, with the aerial
››› Fig. 197 A pointing upwards. When doing
so , do not
c
over the aerial with your fingers
or with the palm of your hand.
There must be a minimum distance of 2 me-
tres between the remote control and the vehi-
cle. CAUTION
● The ra dio fr
equency remote control con-
tains electronic components. Therefore, avoid
getting it wet and being knocked and protect
it from direct sunlight.
● Use of inappropriate batteries may damage
the remote c
ontrol. For this reason, always re-
place the used battery with another of the
same voltage, size and specifications. For the sake of the environment
● Ple a
se dispose of old batteries so that they
do not harm the environment.

lorate. Observe the legal requirements
for their disposal. Programming the auxiliary heater

Driving
If the battery charge is low, the auxiliary heat-
er w i
l
l switch off automatically or will not
even switch on. This avoids problems when
starting the engine.
● The heater will switch on just once each
time. The timer wi
ll also have to be switched
back on every time it is required. Note
● Noise w i
ll be heard while the auxiliary
heater is running.
● When the air humidity is high and the out-
side temper
ature low, the heating system
may evaporate condensation from the auxili-
ary heater. In this case, steam may be re-
leased from underneath the vehicle. This is
completely normal and there is no need to
suspect a fault!
● If the auxiliary heater runs several times
over a pr
olonged period, the vehicle battery
may run flat. To re-charge the battery, drive
the vehicle for a long distance. As a general
rule, drive for as much time as the auxiliary
heating was working. Driving

Introduction The power steering is not hydraulic but elec-
tromec
h
anical. The advantage of this steer-
ing system is that it disposes of hydraulic
tubes, hydraulic oil, the pump, filter and oth-
er components. The electromechanical sys-
tem saves fuel. While a hydraulic system re-
quires oil pressure to be maintained, electro-
mechanical steering only requires energy
when the steering wheel is turned.
With the power steering system, the assisted
steering function automatically adjusts ac-
cording to the vehicle speed, the steering tor-
que and the wheel turning angle. The power
steering only works when the engine is run-
ning. WARNING
If the power steering is not working then the
st eerin
g wheel is much more difficult to turn
and the vehicle more difficult to control.
● The power steering only works when the
engine is
running.
● Never allow the vehicle to move when the
engine is
switched off.
● Never remove the key from the ignition if
the vehic
le is in motion. The steering may lock and it will not be possible to turn the
st
eerin
g wheel. Control and warning lamps

Driving
WARNING
Turning off the engine while driving will make
st op
ping the vehicle difficult; this could even
result in the loss of control causing an acci-
dent with serious consequences.
● The assisted braking and steering systems,
the airbag sys
tem, seat belts and certain
safety equipment are only active while the
engine is running.
● The engine should only be switched off
when the vehic
le is at a standstill. WARNING
While the engine is running or starting it
cou l
d help reduce the risk of serious injury.
● Never start or leave the engine running in
poorly v
entilated or closed spaces. Exhaust
gas contains carbon monoxide, a toxic, col-
ourless and odourless gas. Carbon monoxide
can cause people to lose consciousness. It
can also cause death.
● Never leave the vehicle unattended if the
engine is
running. The vehicle could move off
suddenly or something unexpected could
happen resulting in damage and serious in-
jury.
● Never use start boosters. Cold start sprays
coul
d explode or increase the engine speed
unexpectedly. WARNING
The components of the exhaust system reach
ver y
high temperatures. This could cause a
fire and considerable damage.
● Always park your vehicle so that no part of
the exhau
st system can come in contact with
flammable materials (such as wood, leaves,
dried grass, spilled fuel, etc.).
● Do not apply additional underseal or anti-
corro
sion coatings to the exhaust pipes, cata-
lytic converter, heat shields or the diesel par-
ticulate filter. Ignition lock

Operation
●
Do not p u
sh or tow start the engine. Un-
burnt fuel could damage the catalytic con-
verter. For the sake of the environment
Do not warm the engine at idle speed; start
driv ing immedi
ately if the visibility is OK.
This helps the engine reach operating tem-
perature faster and reduces emissions. Note
● For e x
ample, if the key battery is very worn
or flat, the engine cannot be started with the
starter button. In this case, remove the igni-
tion button from the lock and insert the key.
● Electrical devices with a high power con-
sumption are sw
itched off temporarily when
the engine starts.
● When the engine is started cold, there may
be stron
g vibrations for a few moments for
technical reasons. This is quite normal, and
no cause for concern.
● At temperatures below +5°C (+41°F),
