Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see “Checking tire infla-
tion pressure” in Section 7−2 and “Vehicle load
limits” in Section 2.

7. “TUBELESS” or “TUBE
TYPE”— A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.
8. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”
in Section 7 −2.
9. Maximum cold tire inflation pressure— This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see “Tires” in Section 8.
10.Summer tire or all season tire— An all season tire has “M+S”
on the sidewall. The tire not
marked with “M+S” is a summer
tire. For details, see “Types of
tires” in this Section.

Temperature A, B, C— T he tem per a-
ture grades are A (the highest), B,
and C, representing the tire’s resis-
tance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No.109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.

CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.

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.

CAUTION
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
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 warmup 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 overrev-
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.

3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see “Coolant type
selection” in Section 7 −2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in “P” (auto-
matic) or reverse (manual).
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.
If you have a flat tire—

CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in “P” (automatic) or reverse
(manual). Block the wheel diag-
onally opposite to the one be-
ing changed if necessary.
Make sure to set the jack prop-
erly in the jack point. Raising
the vehicle with jack improper-
ly positioned will damage the
vehicle or may allow the ve-
hicle to fall off the jack and
cause personal injury.
 Never get under the vehicle
when the vehicle is supported
by the jack alone.
 Use the jack only for lifting
your vehicle during wheel
changing.
 Do not raise the vehicle with
someone in the vehicle.
 When raising the vehicle, do
not place any objects on top
of or underneath the jack.
 Raise the vehicle only high
enough to remove and change
the tire.NOTICE
Do not continue driving with a
deflated tire. Driving even a
short distance can damage a
tire and wheel beyond repair.
