Toyota Sienna 2001 Operating Manual page 154

The vehicle skid control system activates
when the vehicle speed is about more
than 15 km/h (9 mph).
While the "VSC" warning light and "TRAC
OFF" indicator/warning light come on, the
vehicle skid control system cannot be op-
erated.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the vehicle
skid control is in the self–check mode and
does not indicate a malfunction.

CAUTION
D
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, it is not that your vehicle
is absolutely safe. Reckless driving
will result in an unexpected acci-
dent. Always keep safety driving in
mind. If the slip indicator light fla-
shes and/or an alarm sounds, spe-
cial care should be taken while
driving.
D
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer.

FAILURE WARNING
These lights warn that when there is a
problem somewhere in the vehicle skid
control system.

key is turned to "ON", and will go off after
about a few seconds.

when applied, there is no problem to con-
tinue your driving.
If any of the following conditions occur,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle:
D
The "VSC" warning light and "TRAC
OFF" indicator/warning light do
come on after the ignition is turned to
on.

The "VSC" warning light and/or "TRAC
OFF" indicator/warning light are left on
after the ignition is turned to on.
