[ i] Tips
• Do not attach any stickers to the windshield in front of the two
light sensors, as this would interfere with both the automatic oper ­
ation of the headlights and the automatic dimming of the inside
mirror(sl.
• If the vehicle is remotely unlocked and locked
three times in
succession,
leaving home will not turn on the lights a fourth time to
safeguard the battery and lights .
• If you wish to use the coming home/leaving home function regu ­
larly, you can leave it activated at all times without risking perma­
nent strain on the electrical system. As the system is controlled by
light sensors, it wi ll only be energized in darkness.
• Frequent use of the coming home/leaving home function for
approaching and departing a vehicle parked in the dark wil l strain
the battery. This applies particularly if only short distances are
driven between stops . Occas ionally drive longer distances to make
sure the battery is recharged sufficiently.
• If the fog lights have been switched on by the coming
home/leaving home function, they will always be switched off when
you switch on the ignition .•

• If you have to leave your vehicle-even for just a minute- always
remove the ignition key and take it with you. This is especially
important if you are going to leave children behind in the vehicle.
The children could start the engine or use other vehicle controls.
Unsupervised use of vehicle controls (for example, power
windows) can cause serious personal injuries.

If the vehicle battery has been disconnected and then reconnected,
then you must leave the key in position
0 for about 5 seconds
before you can start the engine. •

The ignition key can only be removed when the selector
lever is in the
"P" (Park) position.
After switching off the ignition, the ignition key can only be
removed from the ignition lock when the selector lever is in the

Starting and stopping the engine
Starting the engine

A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This is
normal and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 330

_& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
