In addition to the warning lamp ,am essage
appears in the multifunction display. Observe
the information on display messages
( Y
page 196).
It may take up to ten minutes for am alfunction
of the tire pressure monitor to be indicated .A
malfunction wil lbei ndicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after af ew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at ag as station with ap ressure 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.
The operation of the tire pressure monitor can
be affected by interference from radi ot ransmit-
ting equipment (e.g. radi oh eadphones, two-way
radios) that may be being operated in or near the
vehicle.
Checking the tire pressure electroni-
cally X

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 af ew minutes
messag ea ppears.
After at each-in process, the tire pressure mon-
itor automatically detects new wheel sorn ew
sensors. As long as ac lear allocation of the tire
pressure valu etot he individual wheel sisn ot
possible, the Tire Pressure Monitor Active
display messag eiss hown 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 pressure of the wheel that has been removed for af ew
minutes. If this occurs, note that the valu ed is-
played for the positio nw here the spare wheel is
mounted is not the same as the current tire
pressure of the emergency spare wheel.
Tire pressure monitor warning mes-
sages If the tire pressure monitor detects ap ressure
loss in one or more tires, aw arning messag ei s
shown in the multifunction display. The yellow
tire pressure warning lamp then lights up. R
If the Please Correct Tire Pressure
messag ea ppears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunity arises. R
If the Check Tires messag ea ppears in the
multifunction display, the tire pressure in at
least one tire has droppe ds ignificantly. The
tires must be checked. R
If the Warning Tire Malfunction message
appears in the multifunction display, the tire
pressure in at least one tire has droppe ds ud-
denly .T he tires must be checked.
Observe the instructions and safety notes in the
display messages in the "Tires" section
( Y
page 196).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displaye df or the
wrong positions for as hort time. This is rectified
after af ew minutes of driving, and the tire pres-
sures are displaye df or the correct positions.
Restarting the tire pressure monitor When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp sgoo ut. The monitor uses the cur-
rently set tire pressures as the reference values
for monitoring. In most cases, the tire pressure
monitor wil la utomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as describe dh ere. The tire
pressure monitor then monitors the new tire
pressure values. X
Set the tire pressure to the valu er ecommen-
ded for the corresponding driving situation on
the Tire and Loading Information placard on
the driver's side B-pilla r( Y

wise ,y ou rv ehicl ec ould be damaged.
Observe the following when raising the vehicle: R
To rais et he vehicle, only use the vehicle-spe-

parking brake whil et he vehicl eisr aised.R
The jack must be placed on af irm, flat and
non-slip surface. On al oose surface, al arge,
flat, load-bearing underlay must be used .Ona
slippery surface, an on-slip underlay must be
used ,e .g. rubber mats.R
Do not use wooden blocks or similar objects
as aj ack underlay .O therwise, the jack wil ln ot
be abl etoa chieve its load-bearing capacity
due to the restricted height. R
Make sure that the distance betwee nt he
underside of the tires and the ground does not
exceed 1.2 in (3 cm). R
