21. Electronic Throttle Control (ETC) Light
This light will turn on briefly as a bulb check
when the ignition switch is turned ON. This
light will also turn on while the engine is
running if there is a problem with the Elec-
tronic Throttle Control (ETC) system.
If the light comes on while the engine is running, safely
bring the vehicle to a complete stop as soon as possible,
place the shift lever in PARK, and cycle the ignition key.
The light should turn off. If the light remains lit with the
engine running, your vehicle will usually be drivable.
However, see an authorized dealer for service as soon as
possible.
If the light is flashing when the engine is running,
immediate service is required. In this case, you may
experience reduced performance, an elevated/rough idle
or engine stall, and your vehicle may require towing.
Also, have the system checked by an authorized dealer if
the light does not come on during starting.
22. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
