CAUTION
After inserting the tab, make sure
that the tab and buckle are locked,
and the lap and shoulder portions
of the belt are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, it cannot protect your
child from injury. Contact your
Toyota dealer immediately. Do not
use the child restraint system until
the seat belt is fixed.
2. Fully extend the shoulder belt to put itin the lock mode. When the belt is
then retracted even slightly, it cannot

CHILD RESTRAINT SYSTEM
INSTALLATION
Ty p e A —1. Widen the clearance between the seat cushion and seatback a little
and confirm the position of the low-
er anchorages near the tag on the
seatback.
2. Latch the hooks of lower straps onto the anchorages and tighten the lower
straps.
Ty p e B — 1. Widen the clearance between the seat cushion and seatback a little
and confirm the position of the low-
er anchorages near the tag on the
seatback.
2. Latch the buckles onto the anchor- ages.
If your child restraint system has a top
strap, it should be anchored. (For the
installation of the top strap, see “—Using
a top strap” on page 65 in this section.)
For the installation details, refer to the in-
struction manual equipped with each prod-
uct.CAUTION
When using the lower anchorages
for the child restraint system, be
sure that there are no irregular ob-
jects around the anchorages and
that the seat belt is not caught.
Push and pull the child restraint
system in different directions to
make sure it is secure. Follow all
the installation instructions pro-
vided by its manufacturer.
Do not install a child restraint sys-
tem on the rear seat if it interferes
with the lock mechanism of the
front seats. This can cause death or
serious injury to a child and front
passenger in case of a sudden
braking or collision.To change the steering wheel angle,
hold the steering wheel, push down the
lock release lever, tilt the steering
wheel to the desired angle and return
the lever to its original position.

(b) Driver’s Seat Belt Reminder Lightand Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not fastened. Unless the driver fastens the
belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Howev-
er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, builtin
sensors in the seat cushion may detect
the pressure, causing the reminder light to
keep flashing. (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” on page 200
in Section 6.

Vehicles with cruise control—When the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 99 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” 118 km/h (73 mph) . . . . . . . . . . .
“L” 65 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. Pull the parking brake lever up fully to securely apply the parking brake.
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.

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 both personal light switches until
“C” appears on the display.
If “C” appears on the display because of
a drastic change in 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.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 watch out for 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.
