– Press the button.The automatic mode maintains a constant temperature inside the
vehicle and dehumidifies the air. Air temperature, air delivery and
air distribution are regulated automatically to reach the desired interior temperature as quickly as possible, and then to maintain
this temperature. The system automatically compensates for any
variations in the outside temperature and for the effect of direct
sunlight.
The automatic temperature regulation only operates at temperature
settings between +16 °C and +28 °C. If a temperature below +16 °C
is selected, LO appears on the display. If a temperature above +28 °C
is selected, the display will show HI. In the two extreme settings the
air conditioner operates continuously with maximum cooling or
heating output, and the temperature is not regulated
automatically.

the ignition will be switched on or off. The steering lock is released
when the ignition is switched on. Diesel engines continue to be
automatically preheated.
The key can be removed only when the ignition is off. The key has to
be pressed in briefly to switch off the ignition. On vehicles with an
automatic gearbox, the selector lever has to be in position P.
Electrical components with a high power consumption are switched
off temporarily while you start the engine.
When starting from cold the engine may be a little noisy for the first
few seconds until oil pressure has built up in the hydraulic tappets.
This is quite normal and no cause for concern.
If the engine fails to start immediately, the starter will be switched
off automatically after a few seconds. Try to start the engine again.
Driving away from a standstill
On some vehicles, the engine revs are automatically increased
slightly as soon as you release the clutch. This helps you drive off
more smoothly.

This message will appear if you try to start the engine when the
selector lever of the automatic gearbox is not in P or N.Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in P. or Please move selector lever to position P. Vehicle
cannot be locked.
For safety reasons, this message will appear and a warning buzzer
will sound if the selector lever of the automatic gearbox is not in
position P after you switch off the ignition. Put the selector lever in
position P; otherwise the vehicle can roll away. If the lever is not in
position P you will not be able to lock the vehicle using the exterior
locking switch on the door handle or the remote control key.

pants could become trapped in the vehicle. The vehicle occupants
could be exposed to extremely high or low temperatures,
depending on the time of year.
•
Never remove the key from the ignition while the vehicle is
moving. The steering lock could engage suddenly, and you would
not be able to steer the car.Caution

Driving 118•
Avoid high engine speeds, full throttle and extreme load condi-
tions until the engine has reached its normal operating tempera-
ture, otherwise this can damage the engine.For the sake of the environment
Do not warm up the engine by running it with the car stationary. You
should drive off immediately whenever possible. This will help avoid
unnecessary exhaust emissions.
Note
If the key should become stuck in the ignition lock, remove the top
part of the key and use it to lock the vehicle.Switching off the engine– Stop the vehicle.
– Automatic gearbox: Move the selector lever to position P
or N.
–Press in the ignition key to switch off the engine.Emergency Off function
If necessary in an emergency, the engine can be switched off while
the vehicle is still moving. The engine will be switched off if you
press and hold the ignition key.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo and the power steering system work only
when the engine is running. You need more strength to steer and
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.
Caution
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for about 2 minutes before
switching it off.
Note
After the engine is stopped the radiator fan may run on for up to
10 minutes, even if the ignition is switched off. The fan may also
start running again after some time if the coolant temperature rises
due to a build-up of heat, or if the engine is hot and the engine
compartment is heated up further by direct sunlight.Starting and stopping the engine
