door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned in different
places depending on the manufacturer. It is
usually located on the door drive unit on the
garage ceiling.
Familiarize yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within reach of the
garage door or gate opener drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
XTurn the SmartKey to position2in the igni-
tion lock (
Ypage 137).
XGet out of the vehicle.
XPress the programming button on the door drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
XGet into the vehicle.
XPress previously programmed button ;,
= or? on the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds. Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break". Proceed as follows:
Rif you live in Canada
Rif you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps.
XPress and hold one of buttons
;to? on
the integrated garage door opener.
After a short time, indicator lamp :lights
up yellow.
XRelease the button.
Indicator lamp :flashes yellow.
XPress button Bof garage door remote
control Afor two seconds, then release it
for t
wo seconds.
XPress button Bagain for two seconds.
XRepeat this sequence on button Bof
remote control Auntil indicator lamp :
lights up green.
When indicator lamp :lights up green:
programming is finished.
When indicator lamp :flashes green: pro-
gramming was successful. The next step is
to synchronize the rolling code.
XRelease button Bof remote control Aof
the garage door drive.
If indicator lamp :lights up red: repeat the
programming process for the correspond-
ing button on the rear-view mirror. When
doing so, vary the distance between remote
control Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.

The tire pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indicat-
ing a pressure loss or malfunction. Whether
the warning lamp flashes or lights up indi-
cates whether a tire pressure is too low or the
tire pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the
tire pressure on one or more tires is signif- icantly too low. The tire pressure monitor is
not malfunctioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(
Ypage 200).
It may take up to ten minutes for a malfunc-
tion of the tire pressure monitor to be indica-
ted. A malfunction will be indicated by the tire
pressure warning lamp flashing for approx-
imately 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.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge.
The tire pressures shown by the on-board
computer refer to those measured at sea
level. At high altitudes, the tire pressure val-
ues indicated by a pressure gauge are higher
than those shown by the on-board computer.
In this case, do not reduce the tire pressures.
The operation of the tire pressure monitor can be affected by interference from radio trans-
mitting equipment (e.g. radio headphones,
two-way radios) that may be being operated
in or near the vehicle.
Checking the tire pressure electroni-
cally
XMake sure that the SmartKey is in position
2 in the ignition lock (
Ypage 137).
XPress the =or; button on the steer-
ing wheel to select the Service
menu.
XPress the9or: button to select
Tire Pressure
.
XPress the abutton.
The current tire pressure of each tire is
shown in the multifunction display.
If the vehicle has been parked for over
20 minutes, the Tire pressure will be
displayed after driving a few
minutesmessage 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 Activedisplay message is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
If an emergency spare wheel is mounted, the
system may continue to show the tire pres-
sure 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
wheel is mounted is not the same as the cur-
rent tire pressure of the emergency spare
wheel.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a pressureloss in one or more tires, a warning message
is shown in the multifunction display and the
yellow tire pressure monitor warning lamp
comes on.
RIf the Correct Tire Pressuremessage
appears in the multifunction display, the
tire pressure in at least one tire is too low
296Tire pressure
Wheels and tires

and must be corrected at the next oppor-
tunity.
RIf theCheckTiresmessage appears in the
multifunction display, the tire pressure in
one or more tires has dropped significantly
and the tires must be checked.
RIf the Warning Tire Malfunctionmes-
sage appears in the multifunction display,
the tire pressure in one or more tires has
dropped suddenly and the tires must be
checked.
Observe the instructions and safety notes in
the display messages in the "Tires" section
(
Ypage 200).
If the wheel positions on the vehicle are rota-
ted, the tire pressures may be displayed for
the wrong positions for a short time. This is
rectified after a few minutes of driving, and
the tire pressures are displayed for the cor-
rect positions.
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 refer-
ence values for monitoring. In most cases, the
tire pressure monitor will automatically
detect the new reference values after you
have changed the tire pressure. However, you
can also define reference values manually as described here. The tire pressure monitor
then monitors the new tire pressure values.
XSet the tire pressure to the value recom-
mended for the corresponding driving sit-
uation on the Tire and Loading Information
placard on the driver's side
B-pillar (
Ypage 291).
Additional tire pressure values for different
loads can also be found on the tire pressure
table on the inside of the fuel filler flap
(
Ypage 291).
XMake sure that the tire pressure is correct
on all four wheels.
XMake sure that the SmartKey is in position
2 in the ignition lock.
