1. To open the fuel filler door, pull the
door toward out as shown.
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.
Do not fill a fuel container on a
plastic truck bed liner, a rubber
truck bed mat, or any other insulat-
ing material. A static electricity
charge could cause a spark and fire
hazard. The proper procedure is to
place an approved fuel container on
the ground away from the truck for
filling.

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.
When installing the cap, turn the cap
clockwise until you hear a click. When
you hear the click, the cap is fully
closed.
If the cap is not tightened 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 tightened se-
curely to prevent fuel spillage 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.Sliding operation
Tilting operation
To operate the moon roof, use the
switches between the personal lights.
The moon roof works when the ignition
switch is in the “ON” position.
The sun shade can be opened or closed
by hand.
Sliding operation—
To open: Push the “SLIDE” switch on the
“  ” (rear) side.
The roof will open and stop partway 135
mm (5.3 in.) from the fully opened posi-
tion. When you push “ ” (rear) side
again, the moon roof will open fully. To
stop the roof partway, push the same side
or “ ” (front) side while the roof is mov-
ing.
As driving with the moon roof opened fully
will cause wind throbs, we recommend
you to drive with the moon roof partway
135 mm (5.3 in.) from the fully opened
position.
The sun shade will be opened together
with the roof.
To close: Push the “SLIDE” switch on the
“  ” (front) side.

NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

(e) 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.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(f) 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 when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic 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.

(q) Fourwheel Drive System Warning
Buzzer
This buzzer reminds you that the transfer
mode is not selected correctly.
If the buzzer sounds when you shift the
transfer from “2WD” to “4HI”, “4LO” to
“4HI”, “4HI” to “4LO”, or “4LO” to “2WD”
mode, follow the instructions in “Four −
wheel drive system” in Section 1 −7. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid level warning light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on.
The following service reminder indica-
tors go off after a few seconds:
“ABS” warning light
“VSC TRAC” warning light
Low tire pressure warning light
Engine oil replacement reminder light
Roll sensing of curtain shield airbag off
indicator light
“AUTO LSD” indicator light
“VSC OFF” indicator light
(four− wheel drive models)
Slip indicator light
The SRS warning light goes off after
about 6 seconds.
There may be the case that the “ABS”
warning light (brake assist system
warning light), “VSC TRAC” warning
light, slip indicator light and “VSC OFF”
(four−wheel drive models) indicator light
stay on for about 60 seconds after the
ignition key is turned to the “ON” posi-
tion. It is normal if they go out after
a whi l e.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
Pushing the tire pressure warning reset
switch does not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The spare tire is also equipped with the
tire pressure warning valve and transmit-
ter. The tire pressure warning light will
turn on if the tire inflation pressure of the
spare tire is low. If a tire goes flat, even
though the flat tire is replaced with the
spare tire, the warning light does not turn
off. Replace the spare tire with the re-
paired tire and adjust the proper tire infla-
tion pressure. The tire pressure warning
light will turn off after a few minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsib ility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).
