SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown. Link the connector to the trailer
brake controller via the sub wire harness
stored in the glove box. The detailed ex-
planation of the sub wire harness circuit
is packed together with the sub wire har-
ness.
Be sure to position the trailer brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use.
TIRES
Ensure that your vehicle’s tires are
properly inflated. See Section 7 −2 and
Section 8 for instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Section
7 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warm −up idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Always keep the automatic transmis-
sion overdrive switch turned on.
Driving with the overdrive switch off
will reduce the fuel economy. (For de-
tails, see “Automatic transmission” in
Section 1 −7.)
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lugging or over −rev-
ving. Use a gear position suitable for
the road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes premature
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tuned −up and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease, brakes not
adjusted, etc. all lower engine
performance and contribute to poor fuel
economy. For longer life of all parts
and lower operating costs, keep all
maintenance work on schedule, and if
you often drive under severe
conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the “Scheduled
Maintenance Guide” or “Owner ’s
Manual Supplement”.)

6. After making sure that no one
is in the vehicle, raise it high
enough so that the spare tire
can be installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.
Standard cab models—To raise the
vehicle, insert the jack handle into the
jack (it is a loose fit) and turn it clock-
wise. As the jack touches the vehicle
and begins to lift, double− check that
it is properly positioned.
Access cab and double cab models—
To raise the vehicl e, insert the jack
handle extension into the jack (it is
a loose fit) and turn it clockwise with
the handle, making sure the handle
remains firmly fitted onto the jack
handle extension. As the jack touches
the vehicle and begins to lift, double −
check that it is properly positioned.CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.
7. Remove the wheel nuts and
change tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the
bolts. Then lift up the wheel and get
at least the top bolt started through
its hole. Wiggle the tire and press it
back over the other bolts.

11. Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designated in Section 8. If the
pressure is lower, drive slowly to the
nearest service station and fill to the
correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
12.Restow all the tools, jack and flat tire securely.
With a spare tire of the same wheel
type as the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified in Section 8 with a
torque wrench. Have a technician re-
pair the flat tire.
With a spare tire of different wheel
type from the installed tires— As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified in Section 8 with a
torque wrench. Have a technician re-
pair the flat tire and replace the spare
tire with it.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” in Section 1−
7.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
If your vehicle is equipped with the
“AUTO LSD” system, you can use it in
this situation. (For details, see “AUTO
LSD system” in Section 1 −7.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.

CAUTION
If the emergency towing hook is used
to get out when your vehicle becomes
stuck in the mud, sand or other
condition from which the vehicle can-
not be driven out under its own pow-
er, make sure to observe the precau-
tions mentioned below. Otherwise, ex-
cessive stress will be put on the
hook and the towing cable or chain
may break, causing serious injury or
damage.
If the towing vehicle can hardly
move, do not forcibly continue the
towing. Contact your Toyota dealer
or a commercial tow truck service
for assistance.
Tow the vehicle as straight ahead
as possible.
Keep away from the vehicle during
towing.
The following methods are effective to
use when your vehicle is stuck in the
mud, sand or other condition from
which the vehicle cannot be driven out
under its own power. Use extreme cau-
tion when towing the vehicle. In addi-
tion, keep away from the vehicles and
towing cable or chain when towing.
Remove the sand and soil in the front
and the back of the tires.
Place stones or wood under the tires. You can purchase a new key at your
Toyota dealer if you can give them the
key number.
See the suggestion given in “Keys” in
Section 1
−2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers can still open the door for you,
using their special tools. If you must
break a window to get in, we suggest
breaking the smallest side window be-
cause it is the least expensive to replace.
Be extremely cautious to avoid cuts from
the glass.

Doors and engine hood
Check that all doors including tailgate op-
erate smoothly and all latches lock se-
curely. Make sure the engine hood sec-
ondary latch secures the hood from
opening when the primary latch is re-
leased.
Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See Section 7 −2 for additional
information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See Sec-
tion 7 −2 for additional information.
When checking the tires, make sure
no nuts are missing, and check the
nuts for looseness. Tighten them if
necessary.
Tire rotation
Rotate the tires according to the
maintenance schedule. (For sched-
uled maintenance information, please
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.) See Section 7 −2 for additional
information.
Be on the alert for changes in perfor-
mance, sounds, and visual tip −offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat −looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continually
higher than normal
Engine continually runs hot; oil pres-
sure gauge stays low
If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

Access cab models Keep your tire inflation pressures
at the proper level.
The recommended cold tire inflation
pressures, tire
sizes and the com-
bined weight of occupants and cargo
(payload) are described in Section 8.
The recommended tire inflation pres-
sures and tire size s are also on the
tire and loading information label.
You should check the tire inflation
pressure every two weeks, or at least
once a month. And do not forget the
spare!
The following instructions for
checking tire inflation pressure
should be observed:
 The pressure s hould be
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading. 
If you cannot adjust the tire
pressure when the tires are
cold, add 20 to 30 kPa more to
the front tires and rear tires than
the cold tire pr essure, but never
exceed the maximum cold tire
pressure molded on the tire side-
wall.
 Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
 Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
 Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.
