(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6. (f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.

For ways to decrease the vehicle speed,
see “Cruise control” in this section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(e) Using “2” and “L” positions
The “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “2” or “L”, you
can start the vehicle in motion as with the
lever in “D”.
With the selector lever in “2”, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
“2” 120 km/h (74 mph) . . . . . . . . . . .
“L” 64 km/h (40 mph) . . . . . . . . . . . .
 Do not continue hill climbing or
hard towing for a long time in the
“2” or “L” position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, “D” position should
be used in hill climbing or hard
towing.
(f) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(g) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.

The power outlets are designed for
power supply for car accessories.
The key must be in the “ACC” or “ON”
position for the power outlets to be used.

12V/120W (front and rear outlets to-
gether).
 To prevent the battery from being
discharged, do not use the power
outlets longer than necessary when
the engine is not running.
 Close the power outlet lids when
the power outlets are not in use.

CALIBRATING THE COMPASS (circling
calibration)
Sometimes the direction display on the
compass may not change after a turn. To
rectify this, stop the vehicle and push and
hold the “COMP” switch until “C” appears
on the display.
If “C” appears on the display because of
the drastic change of the magnetic field,
perform circling calibration.Drive the vehicle in a circle at 8 km/h (5
mph) or less. If there is not enough space
to drive in a circle, drive around the
block.
After driving 1 to 3 circles in the above
method, calibration is completed when the
direction is shown on the display.
If calibration cannot be performed because
of the magnetized vehicle etc., take your
vehicle to Toyota dealer.
If you want to cancel the calibration be-
fore it is complete, push the “COMP”
switch again. Perform circling calibration just after
you have purchased your Toyota. And
then always perform circling calibration
after the battery has been removed, re-
placed or disconnected.
Do not perform circling calibration of
the compass in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
During calibration, do not operate elec-
tric systems (moon roof, power win-
dows, etc.) as they may interfere with
the calibration.
CAUTION
When doing the circling calibration,
be sure to secure a wide space,
and pay attention to people and ve-
hicles in the neighborhood. Do not
violate any local traffic rules while
performing circling calibration.
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.
