Reactivating the system
Once set, the system is automatically re-
set after the alarm stopped automatically
after one minute.
The alarm will activate again under the
same circumstances described in
“Activating the system”.
Stopping the alarm
The alarm will be stopped by the following
these ways:
Unlock any of the side doors or the
back door with the key or wireless re-
mote control transmitter.
Turn the ignition key from the “LOCK”
to “ON” position.
These ways cancel the system at the
same time. If the battery becomes discharged due
to the vehicle being unused for a long
time, etc.,
when the battery is recharged
or replaced, the system will give the
alarm. If this happens, immediately unlock
any of the side doors or the back door
with the key or the wireless remote con-
trol transmitter, and the alarm will stop.
TESTING THE SYSTEM
1. Open all the windows.
2. Set the system as described above. All the side doors and back door should
be locked with the key or wireless re-
mote control transmitter. Be sure to
wait until the indicator light starts flash-
ing.
3. Unlock any side door from the inside. The system should activate the alarm.
4. Stop the alarm as described above.
5. Repeat this operation for the other doors and hood. When testing the
hood, also check that the system is
activated when the battery terminal is
disconnected and then reconnected.
If the system does not work properly,
have it checked by your Toyota dealer.This indicates that the fuel filler door
is on the left side of your vehicle.

When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or al-
low open flames when refueling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.
NOTICE
Avoid opening the fuel filler door
when the left side sliding door is fully
opened. Otherwise, the fuel filler door
may be damaged.
2. To remove the fuel tank cap, turnthe cap counterclockwise by 90 de-
grees (to the pressure point 1), and
then turn it an additional 30 degrees
(to point 2). Pause slightly before
removing it.
It is not unusual to hear a slight swoosh
when the cap is opened.

3. The removed cap can be stored onthe back side of the fuel filler door.
Position the cap so that the hooks point
to the left and right, and set it in the
receptacle on the back side of the door. When installing the cap, turn the cap
clockwise until you hear one click.
When you hear the click, the cap is
fully closed.
If the cap is not installed securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
CAUTION
Make sure the cap is installed se-
curely to prevent fuel sp
illage in
the event of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It is designed
to regulate fuel tank pressure.
NOTICE
To prevent damage to the cap, apply
force only in the turning direction to
the cap. Do not pull or pry it.

(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 does not go off even after
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, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase with the
accelerator pedal depressed down, there
may be a problem somewhere in your
electronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible. Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
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
(On
−Board Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 446
in Section 6.

GASOLINE QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If this does
not rectify your problem, then consult your
Toyota dealer.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
 If driveab ility problems occur (poor
hot starting, vaporizing, engine
knock, etc.), discontinue the use.
 Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY
79 L (21 gal., 17.5 Imp. gal.) The fuel pump shut off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the engine after the fuel pump shut
off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start
it.
CAUTION
Inspect the ground under the vehicle
before restarting the engine. If you
find that liquid has leaked onto the
ground, it is the fuel system has
been damaged and it is in need of
repair. In this case, do not restart the
engine.
If you plan to drive your Toyota in
another country...
First,
comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

CAUTION
Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
Keep the back door and quarter
windows closed while driving. An
open or unsealed back door and
quarter windows may cause exhaust
gases to be drawn into the vehicle.
To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door and quarter
windows closed. Have the cause im-
mediately located and corrected.
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.

When stowing cargo and luggage in
the vehicle, observe the following: Put cargo and luggage in the lug-
gage compartment when at all
possible. Be sure all items are se-
cured in place.
 Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
 For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent cargo and l uggage
from sliding forward during
braking, do not stack anything
in the luggage compartment
higher than the seatbacks.
Keep cargo and luggage low,
as close to the floor as pos-
sible.
 Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.
 Do not drive with objects left
on top of the instrument panel.
They may interfere with the
driver’s field of view. Or they
may move during sharp vehicle
acceleration or turning, and im-
pair the driver’s control of the
vehicle. In an accident they
may injure the vehicle occu-
pants.Cargo capacity depends on the to-
tal weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) – (Total weight of occupants)
STEPS FOR DETERMINING
CORRECT LOAD LIMIT
1. Locate the statement “The com- bined weight of occupants and
cargo should never exceed XXX
pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kilograms or XXX pounds.
4. The resulting figure equals the available amount of cargo and lug-
gage load capacity. For example,
if the “XXX” am ount equals 1400
lbs. and there will be five 150 lb.
passengers in your vehicle, the
amount of available cargo and lug-
gage load capacity is 650 lbs.
(1400–750 (5x150)=650 lbs).

Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.
Your vehicle is designed primarily as a
passenger−and− load− carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
WEIGHT LIMITS
Before towing, make sure the total trail-
er weight, gross combination weight,
gross vehicle weight, gross axle weight
and trailer tongue load are all within
the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station, build-
ing supply company, trucking company,
junk yard, etc.CAUTION
The maximum gross trailer weight
(trailer weight plus cargo weight)
must never exceed the following. Without towing package
907 kg (2000 lb.)
With towing package 1587 kg (3500 lb.)
If towing a trailer and cargo weigh-
ing over 907 kg (2000 lb.), it is
necessary to use a sway control de-
vice with sufficient capacity. The
combination of the gross trailer
weight added to the total weight of
the vehicle, occupants and vehicle
cargo must never exceed a total of
the following.
