with the integrated garage door opener,
persons in the range of movement of the
garage door can become trapped or struck by
the garage door. There is arisk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbo nmonoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
The HomeLink ®
garage door opener
integrated in the rear-view mirror allows you
to operate up to three different door and gate
systems.
Only operate garage doors using the
integrated garage door opener if:
R they are equipped with a safety stop and
reverse feature, and
R they conform to the current U.S. safety
standards.
When programming a garage door opener,
park vehicle outside the garage.
i Certain garage door drives are
incompatible with the integrated garage

If the tire pressure monitor is
malfunctioning, it may take more than ten
minutes for the tire pressure warning lamp
to inform you of the malfunction by flashing
for approximately one minute and then
remaining lit.
When the malfunction has been rectified,
the tire pressure warning lamp goes out
after a few minutes of driving.
i The tire pressure values indicated by the
on-board computer may differ from those
measured at a gas station with a pressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level.Ath igh altitudes, the tire pressure
values indicated by a pressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the
tire pressures.
i The operation of the tir epressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking the tire pressure
electronically X
Make sure that the SmartKey is in position
2(Y page 141) in the ignition lock .
X Press the 0002or0005 button on the
steering wheel to select the Servicemenu.
X Press the 0003or0004 button to select
Tire Pressure .
X Press the 000Bbutton.
The current tire pressure of each tire is
show ninthe multifunction display.
If the vehicle has been parked for over
20 minutes ,the Tire pressures will be
displayed after driving a few
minutes message appears.
After a teach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as a clear allocation of
the tire pressure value to the individual wheels is not possible, the
Tire Pressure Monitor Active display message is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
i If a spare wheel/emergency spare wheel
is mounted, the system may continue to
show the tire pressure of the wheel that has
been removed for a few minutes. If this
occurs, note that the value displayed for
the position where the spare tire is
mounted is not the same as the spare
wheel/emergency spare wheel's current
tire pressure.
Tire pressure monitor warning
messages If the tire pressure monitor detects a
significant pressure loss on one or more tires,
a warning message is shown in the
multifunction display.
Awarning tone also
sounds and the tire pressure warning lamp
lights up in the instrumen tcluster.
Each tire that is affected by a significant loss
of pressure is highlighted with a color.
If the following message appears in the
multifunction display: Correct Tire Pressure:
X
Check the tire pressure on all four wheels
and correct it if necessary.
i If the wheel positions on the vehicle are
rotated, the tire pressures may be
displayed for the wrong positions for a
shor ttime. This is rectified after a few
minutes of driving, and the tire pressures
are displayed for the correc tpositions.
Restarting the tire pressure monitor When you restart the tire pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitoring system
recognizes the new reference values
automatically.320
