The tire pressure monitor has ay ellow warning
lamp in the instrument cluster for indicating
pressure loss or am alfunction. Whether the
warning lamp flashes or lights up indicates
whether at ire pressure is too low or the tire
pressure monitor is malfunctioning: R
if the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal-
functioning. R
if the warning lamp flashes for approximately
am inute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, am essage
appears in the multifunction display .O bserve
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 will be indicated 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 gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a
pressure gage 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 interferenc ef rom radio transmit-
ting equipment (e.g. radio headphones, two-way
radios) that may be being operated in or near the
vehicle.

pressure value to the individual wheels is not
possible, the Tire Pressure Monitor Active
display message is shown instead of the tire
pressure display .T he tire pressures are already
being monitored.
If an emergenc ys pare wheel is mounted, the
system may continue to show the tire pressure
of the wheel that has been removed for af ew
minutes. Be aware that the value displayed for
the position where the emergenc ys pare wheel
is fitted is not the same as the current tire pres-
sure of the emergenc ys pare wheel.

is shown in the multifunction display .T he yel-
low tire pressure warning lamp then lights up. R
If the Please Correct Tire Pressure
message appears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunit ya rises. R
If the Check Tires message appears in the
multifunction display ,t he tire pressure in at
least one tire has dropped significantly. The
tires must be checked. R
If the Warning Tire Malfunction message
appears in the multifunction display ,t he tire

denly. The tires must be checked.
Observe the instructions and safety notes in the

If the wheel positions on the vehicle are rotated,
the tire pressures may be displayed for the
wrong positions for as hort time. This is rectified
