Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously: the system
is armed
>If the indicator lamp flashes during arm-
ing: doors, engine hood or luggage
compartment lid are not properly
closed. Even if you do not close the
alerted area, the system begins to mon-
itor the remaining areas, and the indica-
tor lamp flashes continuously after
approx. 10 seconds. However, the inte-
rior motion sensor is not activated
>If the indicator lamp goes out on dis-
arming: no manipulation or attempted
intrusions have been detected in the
period since the system was armed
>If the indicator lamp flashes on disarm-
ing until the key is inserted in the igni-
tion lock, but for approx. 5 minutes at
the most: your vehicle has been manip-
ulated in the meantime.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered in garages with
elevator ramps, for instance, or when the
vehicle is transported by trailer or train:
Lock, i.e. arm twice. Press the but-
ton on the remote control twice in succes-
sion, refer to page 27, or lock twice with
the key, refer to page 30.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are switched off as long as the system is
armed.
Interior motion sensor
In
order for the interior motion sensor to
function properly, the windows and glass
roof must be completely closed.
However, switch the interior motion sensor
off, refer to Avoiding unintentional alarms, if
>children or animals are to remain in the
vehicle
>the windows or glass roof are to remain
open.
Windows
Opening and closing windows
As of ignition key position 1:
>Press the switch up to the resistance
point:
The window continues to move down-
ward as long as you continue to hold
the switch
>Briefly press the switch beyond the
resistance point:
The window moves downward auto-
matically. Press the switch again to
stop the opening movement.
You can close the windows in the same
manner by pulling the switch.
After switching off the ignition
You can still operate the windows:
>In the radio position for a longer time
>For approx. 1 minute in position 0 or
with the ignition key removed.

Refueling
Fuel filler door
Always switch off the engine before
refueling. If you do not, fuel cannot be
filled into the tank and a message on the
Control Display will appear.<
To open and close: press the rear edge of
the fuel filler door.
Manual release
In the event of an electrical defect in the
system, you can release the fuel filler door
manually:
1.In the luggage compartment, raise the
floor mat and the cover located beneath
it
2.Open the snap fasteners of the right
side panel and take off the side panel
3.Pull the knob with the gas pump sym-
bol.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these containers can leak, cause an explosion, or
lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
service station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
nozzle during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Closing the fuel filler cap:
Fit the cap and turn it clockwise until you
clearly hear a click.
Close the fuel filler cap carefully after
refueling, until a click is heard. While
closing, be sure not to squeeze the strap
which is fastened to the cap. A loose or
missing cap will activate the message
Check Gas Cap on the Control Display.<
Fuel tank capacity: approx. 18.5 gallons/
70 liters, of which approx. 2.1 gallons/
8 liters reserve.
Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<

Engine oil
Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick 4 out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material 4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
The oil quantity between the two marks on
the dipstick is approx. 1.6 US quarts/
1.5 liters. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
