88nTire Pressure Warning (RDW)
Repeat this process after altering the
tire inflation pressure, changing the tire
or rotating the wheels.
The concept
The tire-pressure warning system,
RDW, monitors the tire inflation pres-
sure in all four tires while driving. The
system provides an alert whenever the
inflation pressure has dropped signifi-
cantly in one of the tires.
Do not carry out any further system
activation on the target condition that
has already been "learned" after
correcting the inflation pressure.
So that the RDW can "learn" the correct
tire inflation pressure, check the infla-
tion pressure in all the tires, comparing
them to the values in the inflation pres-
sure table (page 27), making correc-

tions if necessary. Then activate the
system.
1 Turn the ignition key to position 2 (do
not start the engine).
The Check Control (refer to page 72)
will inform you if the tire pressure of one
the tires has dropped significantly.
2 Press and hold the button (arrow)
until the message "SET TIRE
PRESSURE" is displayed for a few
seconds in the Check Control.
3 The RDW initiates an automatic
learning process during driving, and
stores this target condition. This
one-time learning process takes at
least 10 minutes, and from that point
on the RDW can identify and report a
flat tire.
