Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below.
Total load capacity (pay load)
Total load capacity means combined
weight of occupants, cargo and lug-
gage. Tongue load is included when
trailer towing. For the total load ca-
pacity about your vehicle, see “Pay-
load” in Section 8.
Seating capacity:
Single cab modelsTot al 3
Access cab models Models with front bench seat: To-
tal 6 (Front 3, Rear 3)
Models with front separate seat:
Total 5 (Front 2, Rear 3)
Seating capacity means the maxi-
mum number of occupants whose
weight is supposed to be 68 kg (150
lb.) per person. Depending on the
weight of person, the seating ca-
pacity given may exceed the total
load capacity. NOTICE
Even if the number of occupants
are within the seating capacity,
do not exceed the total load ca-
pacity.
Towing capacity
Towing capacity means the maximum
gross trailer weight (trailer weight plus
its cargo weight) that your vehicle is
able to tow. For the towing capacity
about your vehicle, see “Towing ca-
pacity” in Section 8.
Cargo capacity
Cargo capacity may increase or de-
crease depending on the size (weight)
and the number of occupants. For de-
tails, see “Capacity and distribution”
that follows.
CAUTION
Do not apply the load more than
each load limit. That may cause
not only damage to the tires, but
also deterioration to the steering
ability and braking ability, caus-
ing an accident.

When stowing cargo and luggage in
the vehicle, observe the following:
 Put cargo and luggage in the rear
deck when at all possible. Be sure
all items are secured 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
behind the front seats higher
than the seatbacks (access cab
models). Keep cargo and lug-
gage low, as close to the floor
as possible.
 Never allow anyone to ride in
the rear deck. It is not designed
for passengers. They s hould
ride in their seats with their
seat belts properly fastened.
Otherwise, they are much more
likely to suffer serious bodily
injury, in the event of sudden
braking or a collision.
 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).
5. Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available car-
go and luggage load capacity of
your vehicle.
For details about trailer towing, see
“Trailer towing” in Section 3.

EXAMPLE ON YOUR VEHICLE
In case that 2 people with the com-
bined weight of A kg (lb.) are riding
in your vehicle with the total load ca-
pacity of B kg (lb.)
∗, the av ailable
amount of cargo and luggage load ca-
pacity will be C kg (lb.) as follows:
B kg (lb. ) – A kg (lb. ) = C kg (lb. )
∗: Total load capacity is shown in the tire and loading information label.
(For the tire and loading information
label, See “Checking tire inflation
pressure” in Section 7 −2. From this condition, if 3 more passen-
gers with the combined weight of D
kg (lb.) get on, the available cargo
and luggage load will be reduced E
kg (lb.) as follows:
C kg (lb. ) – D kg (lb. ) = E kg (lb. )
As shown in the above example, if the
number of occupants increases, the
cargo and luggage load equaling the
combined weight of occupants who
got on later must be reduced. In other
words, if the incr
ease in the number
of occupants causes the excess of
the total load capacity (combined
weight of occupants plus cargo and
luggage load), you have to reduce the
cargo and luggage on your vehicle.
For details about total load capacity,
see “Vehicle load limits” in this Sec-
tion.

CAUTION
Even if the total load of occu-
pant’s weight and the cargo load
is less than the total load capac-
ity, do not apply the load uneven-
ly. That may cause not only dam-
age to the tire but also deteriora-
tion to the steering ability due to
unbalance of the vehicle, causing
an accident.
Determine what kind of tires your
vehicle is originally equipped with.
1. Summer tires
Summer tires are high −speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow −covered or icy roads.
For driving on snow −covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round. All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described “—Tire symbols” in Section
2.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacturer’s designated
tires, and never mix tires or
wheels of the sizes different
from the originals.

1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. Once you turn the ignition key to “START”
position and release it, the cranking hold
function continues to crank the engine in
“ON” position until it starts.
The function stops cranking the engine
after about 25 seconds maximum if the
engine has not started yet. When you
crank the engine again, wait a few sec-
onds and restart it.
If you hold the key in “START” position,
the function will keep cranking for about
30 seconds maximum. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Manual transmission: Press the clutch
pedal to the floor and shift the trans-
mission into neutral. Hold the clutch
pedal to the floor until the engine is
started. A starter safety device will pre-
vent the starter from operating if the
clutch pedal is not fully depressed.
Automatic transmission: Put the se-
lector lever in “P”. If you need to re-
start the engine while the vehicle is
moving, put the selector lever in “N”.
A starter safety device will prevent the
starter from operating if the selector
lever is in any drive position.
4. Automatic transmission only:
De-
press the brake pedal and hold it to
the floor until driving off.

Before starting the engine, be sure to fol-
low the instructions in “(a) Before crank-
ing”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
1. 5VZ −FE engine—With your foot off the
accelerator pedal, crank the engine by
turning the ignition key to “START”
position. Release it when the engine
starts.
2UZ− FE engine—With your foot off the
accelerator pedal, turn the ignition key
to “START” position, then release it.
2. After the engine runs for about 10 se- conds, you are ready to drive.
If the weather is below freezing, let the
engine warm up for a few minutes before
driving.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” in Sec-
tion 4.NOTICE
 5VZFE engine only—Do not crank
for more than 30 seconds at a time.
This may overheat the starter and
wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp −edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P” (automatic) or in first or
reverse (manual). If necessary, block
the wheels.
