notes on the recommended tire pressure
(Y
page 290).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. follow-
ing penetration by a foreign object. In this
event, brake the vehicle until it comes to a
standstill. Do not carry out any sudden steer-
ing maneuvers.
The tire pressure monitor has a yellow 0077
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss (Canada). Depending on how
the warning lamp flashes or lights up, an
underinflated tire or a malfunction in the tire
pressure monitor is displayed:
R if the 0077 warning lamp is lit continuously,
the tire pressure on one or more tires is
significantly too low. The tire pressure mon-
itor is not malfunctioning.
R USA only: if the 0077warning lamp flashes
for 60 seconds and then remains lit con-
stantly, the tire pressure monitor is mal-
functioning.
Only vehicles with steering wheel buttons: the
on-board computer displays information on
tire pressure. After a few minutes of driving,
the current tire pressure of each tire is shown
in the on-board computer.
USA only: if the tire pressure monitor is mal-
functioning, it may be more than 10 minutes
before the malfunction is shown. The 0077
tire pressure warning lamp flashes for
60 seconds and then remains lit. When the
malfunction has been rectified, the 0077tire
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 value
indicated by a pressure gauge are higher than
those shown by the on-board computer. In
this case, do not reduce the tire pressures. If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated
inside the vehicle or in the vicinity of the vehi-
cle, this can interfere with the operation of
the tire pressure monitor.

Tire pressure loss warning system Vehicles with steering wheel buttons
If the tire pressure monitor detects a signifi-
cant pressure loss on one or more tires, the
on-board computer displays a warning mes-
sage. The 0077tire pressure loss warning 294

lamp in the instrument cluster (Y

lights up.
The tire pressure is shown in 2 red rectangles.
The pressure of the tire concerned is shown
in one of the two rectangles (Y page 199).
Additionally, a warning tone sounds.
Each tire that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
Restarting the tire pressure monitor When you restart the tire pressure monitor,
the currently set tire pressure are taken as
reference values for monitoring.
In most cases, the tire pressure monitor
detects the new reference values automati-
cally, e.g. after you have:
R changed the tire pressure
R mounted
R mounted new wheels or tires
However, you can also define reference val-
ues manually as described here.
Before restarting the tire pressure moni-
tor:
X Set the tire pressure to the value recom-
mended on the Tire and Loading Informa-
tion placard or the tire pressure table on
the B-pillar on the driver's side
(Y page 290).
Observe the notes on tire pressure when
doing so (Y page 290).
X Make sure that the tire pressure is correct
on all four wheels. Restarting the tire pressure monitor
(vehicles without steering wheel but-
tons):
X
Turn the key to position 2in the ignition
lock.
X Press the 0079menu button on the instru-
ment cluster repeatedly until the display
shows the following message:

The tire pressure monitor activation proc-
ess has begun. The tire pressures meas-
ured for the individual wheels are stored as
the new reference values, provided that the
tire pressure monitor considers them to be
plausible.
If you wish to cancel the restart:
X Press the 0075button or the 0079menu button
on the instrument cluster.
The activation process is canceled auto-
matically if 30 seconds elapse without
input.
