Tire Pressure Warning (RDW)
The concept
The Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system detects
whenever the inflation pressure in a tire
drops significantly.
Controlling the tire pressure is based
on monitoring the speed of the tires
relative to each other. A flat tire is
detected and reported because the
speed suddenly deviate drastically from
one another.
Initializing the system
Initializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 27),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Continue to press the button until the
yellow indicator lamp in the instru-
ment cluster lights up. After a short
time, the indicator lamp will go out
automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as the value to be measured against,
and from that point on, can detect
and report a flat tire.
