When indicator lamp:flashes green: pro-
gramming was successful. The next step is to
synchronize the rolling code.
XRelease button Bof remotec ontrolAof the
garage door drive.
If indicator lamp :lights up red: repeat the
programmingp rocess for the corresponding
button on the rear-view mirror. When doing
so, vary the distanc ebetween remotec ontrol
A and the rear-view mirror.
The required distanc ebetween remotec on-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take not eofthe following instruc-
tions:
RCheck the transmitter frequenc yused by
garage door drive remotec ontrolAand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remotec ontrolAfor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequenc yrange of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A.This increases the likelihood that
garage door remotec ontrolAwill transmit a
stron gand precise signal to the integrated
garage door opener.
RWhen programming, hold remotec ontrolA
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at adistanc ebetween 2and
8i nches (5to 20 cm) or at the same angle but
at varying distances.
RIf another remotec ontrolAis available for
the same garage door drive, repeat the same
programmings teps with this remotec ontrol
A.B eforep erforming these steps, make sure
that new batteries have been installed in
garage door drive remotec ontrolA.
RNote that some remotec ontrols only transmit
for alimited amount of time (the indicator
lamp on t
he remotec
ontrol goes out). Press button
Bon remotec ontrolAagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.

Engine oil
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in ad ifferent location.
When checking the oil level:
Rpark the vehicle on alevel surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait about 30 minutes before carrying
out the measurement
Checking the oil level using the oil dip-
stick
