the following:
Apply a heavy load to the front pas-
senger seat.

CAUTION
Since the mirror surface can get hot,
do not touch them when the switch
is on.
Make sure you turn the defogger off when
the window is clear. Leaving the defogger
on for a long time could cause the 12 volt
battery to discharge. The defogger is not
designed for drying rain water or for melt-
ing snow.
If the outside rear view mirrors are heavi-
ly coated with ice, use a spray de−icer
before operating the switch.

When cleaning the inside of the rear
window, be careful not to scratch or
damage the heater wires or connec-
tors.

The gauge indicates the approximate
quantity of fuel remaining in the tank
when the “IGON” mode is enabled.
Nearly full–Indicator at “F”
Nearly empty–Indicator at “E”
It is a good idea to keep the tank over
1/4 full.
When you refuel on a slope, the indicator
may not show the correct level.
When you refuel less than about 11.4 L
(3.0 gal., 2.5 lmp.gal.), the fuel indicator
may not change.
After the 12 volt battery is reconnected,
one segment will flash for a while.Depending on the ambient temperature,
the fuel quantity is less than 45 L (11.9
gal., 9.9 lmp.gal.) even at “F”. However,
this does not affect the fuel consumption
and the remaining fuel ratio indicated on
the gauge. (For details, see “Fuel” on
page 320.)
If the fuel gauge display flashes, there
may be a problem in the system. In this
case, contact your Toyota dealer as soon
as possible.
