2008 TOYOTA LAND CRUISER Owners Manual

406 4−3. Do−it−yourself maintenance
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advanced warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, the tire pressure warning valves and transmitters must
be installed. (
P. 392)
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in the
Owner ’s Manual, as this may result in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a tube−
less tire. Doing so may result in an accident, causing death or serious
injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by your Toyota
dealer or other qualified service shop. In addition, make sure to purchase
your tire pressure warning valves and transmitters at your Toyota dealer.
l
Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non−genuine wheels.
