Air conditioning
Checking programming
If the timer has been switched on after switching the ignition off, the instant
on button
will remain lit for around ten seconds.
WARNING
Never program the independent heating system to be activated and oper-
ated in closed, unventilated areas. The auxiliary heater fumes contain
carbon dioxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
Operating instructions
The auxiliary heater exhaust system located below the vehicle must be kept
clear of snow, mud and other objects. The exhaust gases must not be ob-
structed in any way. The exhaust gases generated by the auxiliary heater are
removed via an exhaust pipe fitted underneath the vehicle.
On heating the vehicle interior, depending on the outside temperature the
warm air is first directed at the windscreen and then to the rest of the vehi-
cle interior through the air vents. If the air vents are turned towards the win-
dows, for example, the form of air distribution may be affected.
Depending on the outside temperature, the temperature at which the auxili-
ary heater warms the vehicle interior may be somewhat higher if the heating
or air conditioner temperature control is set to maximum before switching
the heating on.
Depending on the engine, vehicles with auxiliary heater may be fitted with a
second battery in the luggage compartment that is responsible for powering
the auxiliary heater. Cases in which the auxiliary heater will not switch on
●
The auxiliary heater requires about as much power as the dipped beam
headlights. If the battery charge is low, the auxiliary heater will switch off
automatically or will not even switch on. This avoids problems when starting
the engine.
● The heater will switch just once each time. The timer will also have to be
switched back on every time it is required.
Note
● Noise will be heard while the auxiliary heater is running.
● When the air humidity is high and the outside temperature low, the
heating system may evaporate condensation from the auxiliary heater. In
this case, steam may be released from underneath the vehicle. This is com-
pletely normal and there is no need to suspect a fault!
● If the auxiliary heater runs several times over a prolonged period, the ve-
hicle battery may run flat. To re-charge the battery, drive the vehicle for a
long distance. In general: drive for as much time as the auxiliary heating
was working.

SteeringIntroduction
The power steering is not hydraulic but electromechanical. The advantage
of this steering system is that it disposes of hydraulic tubes, hydraulic oil,
the pump, filter and other components. The electromechanical system
saves fuel. While a hydraulic system requires oil pressure to be maintained,
electromechanical steering only requires energy when the steering wheel is
turned.
With the power steering system, the assisted steering function automatical-
ly adjusts according to the vehicle speed, the steering torque and the wheel
turning angle. The power steering only works when the engine is running.
Additional information and warnings:
● Start and stop the engine ⇒ page 171
● Vehicle battery ⇒ page 291
● Tow starting and towing away ⇒ page 343
WARNING
If the power steering is not working then the steering 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 vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.

You should remember that you will need considerably more power than nor-
mal to steer the vehicle if the power steering is not working correctly or not
at all.
Counter steering assistance system
The counter steering assistance system helps the driver in critical situa-
tions. Additional steering power helps the driver when counter steering.

● Push the lever firmly upwards until it is flush to the steering column
⇒
.
WARNING
Incorrect use of the steering wheel adjustment function and an incorrect
adjustment of the steering wheel can result in severe or fatal injury.
● After adjusting the steering column, push the lever 1
firmly upwards
to ensure the steering wheel does not accidentally change position while
driving.
● Never adjust the steering wheel while the vehicle is in motion. If you
need to adjust the steering wheel while the vehicle is in motion, stop
safely and make the proper adjustment.
● The adjusted steering wheel should be facing your chest and not your
face so as not to hinder the driver's front airbag protection in the event of
an accident.
● When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions to reduce inju-
ries when the driver's front airbag deploys.
● Never hold the steering wheel at the 12 o'clock position or in any oth-
er manner (e.g. in the centre of the steering wheel). In such cases, if the
driver's airbag deploys, you may sustain injuries to your arms, hands and
head.

WARNING
Turning off the engine while driving will make stopping the vehicle diffi-
cult; this could even result in the loss of control causing an accident with
serious consequences.
● The assisted braking and steering systems, the airbag system, seat
belts and certain safety equipment are only active while the engine is
running.
● The engine should only be switched off when the vehicle is at a
standstill.
WARNING
While the engine is running or starting it could help reduce the risk of se-
rious injury.
● Never start or leave the engine running in poorly ventilated or closed
spaces. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never leave the vehicle unattended if the engine is running. The vehi-
cle could move off suddenly or something unexpected could happen re-
sulting in damage and serious injury.
● Never use start boosters. Cold start sprays could explode or increase
the engine speed unexpectedly.

WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as wood, leaves, spilled
fuel, dried grass, etc).
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter, heat shields or the diesel particulate
filter.

engine could accidentally be started and electrical equipment such as
the windows could accidentally be operated resulting in serious injury.
● Never leave children or disabled people alone in the car. They could
be trapped in the car in an emergency and will not be able to get them-
selves to safety. For example, depending on the time of the year, temper-
atures inside a locked and closed vehicle can be extremely high or ex-
tremely low resulting in serious injuries and illness or even death, partic-
ularly for young children.
● Never remove the key from the ignition if the vehicle is in motion. The
steering may lock and it will not be possible to turn the steering wheel.
Note
● If the key is left in the ignition lock with the engine off for long periods,
the vehicle battery will run flat.

WARNING
Cold start sprays could explode or cause a sudden increase in the engine
speed.
● Never use start boosters.
CAUTION
● An attempt to start the engine while driving or starting the engine imme-
diately after turning it off can cause damage to the engine or starter motor.
● When the engine is cold, avoid high revs and heavy acceleration and do
not make the engine work hard.
● Do not push or tow start the engine. Sunburnt fuel could damage the
catalytic converter.
For the sake of the environment
Do not warm the engine at idle speed; start driving immediately if the visi-
bility is OK. This helps the engine reach operating temperature faster and
reduces emissions.
Note
● For example, if the key battery is very worn or flat, the engine cannot be
started with the starter button. In this case, remove the ignition button from
the lock and insert the key.
● Electrical components with a high power consumption are switched off
temporarily when the engine starts.
● When the engine is started cold, there may be strong vibrations for a few
moments for technical reasons. This is quite normal, and no cause for con-
cern.
● At temperatures below +5 °C (+41 °F), smoke may be given off below the
vehicle when the additional heater is connected. Stopping the engine

WARNING
Never switch off the engine while the vehicle is moving. You may lose
control of the vehicle and there is a risk of serious accident.
● The airbags and belt tensioners do not work when the ignition is
switched off.
● The brake servo does not work with the engine off. To stop, the brake
pedal must be pressed with more force.
● As the power steering does not work if the engine is not running, you
will need more strength to steer than normally.
● If the key is removed from the ignition, the steering may lock and it
will not be possible to steer the vehicle.
CAUTION
If the engine has been driven at high speed for a prolonged period of time,
it may overheat when turned off. To avoid engine damage, allow the engine
to run for approximately two minutes in neutral before switching it off.
