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, turn
the 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 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.Sliding 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 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 switch on the “ ”
(front) side. The roof will fully close. To stop the roof
partway, push the same side or “
” (rear)
side briefly.
Tilting operation—
To tilt up: Push the switch on the “UP”
side.
To lower: Push the switch on the opposite
side of “UP”.
You may stop the moon roof at any de-
sired position. The roof will move while
the switch is being pushed and stop when
released.
Key off operation: If all the doors are
closed, it works for 43 seconds even after
the ignition switch is turned off. It stops
working when any of the doors is opened.
Jam protection function: If something
gets caught between the moon roof and
frame during closing operation, the moon
roof stops and opens half way.
If the moon roof receives a strong impact,
this function may work even if nothing is
caught.CAUTION
To avoid serious personal injury, you
must do the following.
While the vehicle is moving, always
keep the heads, hands and other
parts of the bodies of all occupants
away from the roof opening. Other-
wise, they could be seriously in-
jured if the vehicle stops suddenly
or if the vehicle is involved in an
accident.
Before you close the moon roof,
always make sure there is nobody
around the moon roof. You must
also make sure nobody places his
or her head, hands and other parts
of the body in the roof opening. If
someone’s neck, head or hands get
caught in the closing roof, it could
result in a serious injury. When
anyone closes the moon roof, first
make sure it is safe to do so.
Be sure to remove the ignition key
when you leave your vehicle.

Never leave anyone (particularly a
small child) alone in your vehicle,
especially with the ignition key still
inserted. Otherwise, he/she could
use the moon roof switches and get
trapped in the roof opening. Unat-
tended person (particularly a small
child) can be involved in a serious
accident.
Never sit on top of the vehicle
around the roof opening.
Never try jamming any part of your
body to activate the jam protection
function intentionally.
The jam protection function may
not work if something gets caught
just before the window is fully
closed.

While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow any passengers to sit on
top of a foldeddown seatback, or
in the luggage compartment or car-
go area. Persons not properly
seated and/or not properly re-
strained by seat belts can be se-
verely injured in the event of emer-
gency braking or a collision.
During driving, do not allow any
passengers to stand up or move
around between seats. Otherwise,
severe injuries can occur in the
event of emergency braking or a
collision.
Driver seat
CAUTION
The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if
the driver is very close to the airbag.
The National Highway Traffic Safety
Administration (“NHTSA”) advises:
Since the risk zone for driver airbag
is the first 50—75 mm (2—3 in.) of
inflation, placing yourself 250 mm (10
in.) from your driver airbag provides
you with a clear margin of safety.
This distance is measured from the
center of the steering wheel to your
breastbone. If you sit less than 250
mm (10 in.) away now, you can
change your driving position in sever-
al ways:
Move your seat to the rear as far
as you can while still reaching the
pedals comfortably.
Slightly recline the back of the
seat. Although vehicle designs vary,
many drivers can achieve the 250
mm (10 in.) distance, even with the
driver seat all the way forward, sim-
ply by reclining the back of the
seat somewhat. If reclining the back
of your seat makes it hard to see
the road, raise yourself by using a
firm, nonslippery cushion, or raise
the seat if your vehicle has that
feature.
If your steering wheel is adjustable,
tilt it downward. This points the air-
bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec-
ommended by NHTSA above, while
still maintaining control of the foot
pedals, steering wheel, and your view
of the instrument panel controls.

Front passenger seats
CAUTION
The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury es-
pecially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the
airbag as possible with the seatback
adjusted, so the front passenger sits
upright.
CAUTION
Do not adjust the seat while the
vehicle is moving as the seat may
unexpectedly move and cause the
driver to lose control of the vehicle.
Be careful that the seat does not
hit a passenger or luggage.
After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.
After adjusting the seatback, push
your body back against the seat to
make sure the seat is locked in
position.
Do not put objects under the seats.
Otherwise, the objects may interfere
with the seatlock mechanism or
unexpectedly push up the seat posi-
tion adjusting lever and the seat
may suddenly move, causing the
driver to lose control of the vehicle.
While adjusting the seat, do not put
your hands under the seat or near
the moving parts. Otherwise, your
hands or fingers may be caught and
injured.

1. SEAT POSITION ADJUSTING LEVER
Separate and split bench seat: Hold the
center of the lever and pull it up. Then
slide the seat to the desired position
with slight body pressure and release
the lever.
Nonsplit bench seat: Pull the lever up.
Then slide the seat to the desired posi-
tion with slight body pressure and re-
lease the lever. 2. DRIVER’S SEAT CUSHION ANGLE ADJUSTING KNOB
Turn the knob either way.
3. SEATBACK ANGLE ADJUSTING LEVER
Lean forward and pull the lever up.
Then lean back to the desired angle
and release the lever.CAUTION
To reduce the risk of sliding under
the lap belt during a collision, avoid
reclining the seatback any more than
needed. The seat belts provide maxi-
mum protection in a frontal or rear
collision when the driver and the
front passenger are sitting up straight
and well back in the seats. If you are
reclined, the lap belt may slide past
your hips and apply restraint forces
directly to the abdomen. In the event
of a frontal collision, the more the
seat is reclined, the greater the risk
of personal injury.
