(c) Front Passenger ’s Seat Belt Re-minder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the engine switch is turned to “ON”,
the reminder light flashes if a passenger
sits in the front passenger seat and does
not fasten the seat belt. Unless the front
passenger fastens the belt, the light con-
tinues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for about 10 sec-
onds. Then, if the seat belt is still unfas-
tened, the buzzer will sound in a different
tone for 20 seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the driver ’s seat
belt is fastened.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash and
buzzer may sound. (d) Charging System Warning Light
This warning light comes on when the
engine switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while the engine is r
unning, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact your Toyota
dealer.
(e) Malfunction Indicator Lamp
This lamp comes on when the engine
switch is turned to the “ON” position
and goes off after the engine starts.
This means that the warning light sys-
tem is operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
following.
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 does not go off even after
several trips, contact your Toyota dealer
as soon as possible.

If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.
The light does not come on when the
engine switch is turned to the “ON”
position, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(i) Open Door Warning Light
This light remains on until all the doors
are completely closed.
(j) SRS Warning Light
This indicator comes on when the en-
gine switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS airbags and seat
belt pretensioners are operating proper-
ly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system,
“AIR BAG ON” indicator light, “AIR BAG
OFF” indicator light, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, interconnecting wir-
ing and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.The light does not come on when the
engine switch is turned to the “ON”
position or remains on for more than
6 seconds or flashes.
The light comes on or starts flashing
while driving.
If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and “AIR BAG ON”
and “AIR BAG OFF” indicator lights have
a problem. If the light flashes, the SRS
side airbag system and/or curtain shield
airbag system have a problem.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.

On roads with heavy traffic or
sharp bends, an appropriate speed
cannot be maintained and an acci-
dent may occur.
On slippery road surfaces (icy or
snowcovered road surfaces), the
tires will race and you will be un-
able to control the vehicle.
When there is no vehicle detected
ahead on steep downhill slopes, the
preset speed will be easily exceed-
ed because of inefficient engine
braking. (In this case, automatic
braking will not work.) If there is a
vehicle detected ahead, the delay in
deceleration timing could cause se-
rious injury or death.
When the alarm sounds frequently
(because acceleration or decelera-
tion was repeated or sufficient ve-
hicletovehicle distance was not
maintained), an appropriate vehicle
speed cannot be attained and an
accident may occur.On roads with steep and short in-
clines and declines, failure to de-
tect the vehicle ahead will shorten
the distance between your vehicle
and the vehicle ahead and an acci-
dent may occur.
Deceleration cruising function and
approach warning do not operate
when the vehicle ahead is at a stop
or driving very slowly.
If the vehicle ahead of you deceler-
ates abruptly or if another vehicle
cuts in ahead of you, your vehicle
may collide with the vehicle ahead
unless you manually depress the
brake pedal to slow down your ve-
hicle.
Depending on the road configura-
tion (curved, left and right continu-
ous curved, the start or end of a
curve, or narrow driving lanes due
to road construction) or your ve-
hicle condition (steering wheel ma-
neuvering, position in the lane, or
unstable driving because of an acci-
dent or breakdown), vehicles in oth-
er lanes or surrounding objects
may be detected, resulting in a con-
trol failure or the approach warning
activation. This may also result in
a very close distance between vehi-
cles due to a failure to detect the
vehicle ahead.

If “E3” appears on the display, a system
malfunction has been detected.
If this code appears, stop your vehicle in
a safe place, turn the engine switch off,
and then restart it to reset the system. If
the setting still cannot be made or the
same code appears again, the system
might have malfunctioned. Although there
is no problem to continue driving, contact
your Toyota dealer. The conventional cruise control mode is
designed to maintain a set cruising
speed without requiring the driver to
operate the accelerator. Cruising speed
can be set to any speed above 45 km/h
(28 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
In the conventional cruise control
mode, the approach warning does
not activate and no alarm will
sound even if you are too close to
the vehicle ahead, as neither the
presence of the vehicle ahead nor
the vehicletovehicle distance is
detected. Pay special attention to
the distance between your vehicle
and the vehicle ahead. Always con-
firm the setting in the display.
Do not use the conventional mode
in the following conditions, or seri-
ous injury or death could result:
To help maintain maximum control
of your vehicle, do not use conven-
tional cruise control mode when us-
ing dynamic laser cruise control
while driving in heavy or varying
traffic, or on slippery (rainy, icy or
snowcovered) or winding roads.
Be careful about vehicle speed as
it may increase when driving down-
hill with the conventional cruise
control mode selected.

CALIBRATING THE COMPASS (circling
calibration)
Sometimes the direction display on the
compass may not change after a turn. In
this case, the compass needs to be cali-
brated.
To calibrate the compass manually, do the
following;1. Stop the vehicle in a level place and switch the display to the outside tem-
perature. (To switch to this mode, see
“—Outside temperature and cruise in-
formation display” on page 376.) 2. Push and hold both the “MODE” and
“E/M” buttons simultaneously for 10
seconds until the “CAL” indication ap-
pears on the compass display. (At this
time, the compass display is locked in
“N”.)3. 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.
When the “CAL” indication goes off and
the compass returns to the normal mode,
calibration is complete.
If you want to restart the calibration be-
fore it is complete, push both of the
“MODE” and “E/M” buttons simultaneously
for 10 seconds again.

CAUTION
When you load cargo on the roof lug-
gage carrier, observe the following:
Place the cargo so that its weight
is distributed evenly between the
front and rear axles.
If loading long or wide cargo, never
exceed the vehicle overall length or
width. (See “Dimensions and
weights” on page 548 in Section 8
for information on your vehicle
overall length and width.)
Before driving, make sure the cargo
is securely fastened on the roof
luggage carrier.
Loading cargo on the roof luggage
carrier will make the center of the
vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneu-
vers, otherwise it may result in loss
of control or vehicle rollover due to
failure to operate this vehicle cor-
rectly.
If driving for a long distance, on
rough roads, or at high speeds,
stop the vehicle now and then dur-
ing the trip to make sure the cargo
remains in its place.
Do not exceed 68 kg (150 lb.) cargo
weight on the roof luggage carrier.
NOTICE
When loading the luggages, be careful
not to scratch the surface of the
moon roof.

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles). FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5 −M93
in Canada.NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
Select Octane Rating 87 (Research
Octane Number 91) or higher.
Use of unleaded gasoline with an octane
rating lower than 87 may result in engine
knocking. Persistent knocking can lead to
engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
