Changes or modifications to- this system
by other than an authorized service
facility could void authorization to use

The Low Tre Pressure Warning System
(LTPWS) monitors the
air pressure in
each road tire (except the spare tire)
while the car is being driven. The
LTFWS will not warn the driver if a tire
is
already flat before the vehicle is started.
This light comes on whenever a tire
pressure
