However, if towing with a fifth wheel
trailer, the cargo load must be dis-
tributed so that the tongue load is
19 to 21% of the total trailer weight.
Never load the trailer with more
weight in the back than in the front.
About 60% of the trailer load should
be in the front half of the trailer and
the remaining 40% in the rear.
HITCHES Use only a weight carrying hitch de-
signed for the total trailer weight. Toyo-
ta does not recommend using a weight
distribution (load equalizing) hitch.
The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer's instruc-tions.
If using a fifth wheel hitch, the center
of the king pin must be forward of the
axis of the vehicle's rear wheels, and
installed according to the manufactur-
er's instructions.
The hitch ball and king pin should havea light coat of grease.
Toyota recommends that the trailer
hitch, except fifth wheel hitch, be re- moved when not towing to prevent in-jury and/or damage by the hitch in
event of a rear end collision. After re-moving the hitch, the installation area
should be sealed to prevent entry of exhaust fumes and mud.
Do not use an axle-mounting hitch
as it may cause damage to the axle
housing, wheel bearings, wheelsand/ or tires.
NOTICE
BRAKES AND SAFETY CHAINS Toyota recommends trailers with brakes that conform to any applicable
federal and state/provincial regula- tions.
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should cross
under the trailer tongue to prevent thetongue from dropping to the ground in
case it becomes damaged or sepa-
rated. For correct safety chain proce-
dures, follow the hitch or trailer
manufacturer 's recommendations.
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.!
TIRES Ensure that your vehicle's tires are
properly inflated.
The trailer tires should be inflated to
the pressure recommended by the
trailer manufacturer in respect to the
total trailer weight.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden braking.
Remember that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the
turn. Therefore, compensate for this
by making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay atten-
tion to the rear from time to time to pre-
pare yourself for being passed by large trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed.
Steer straight ahead. If you make no
extreme correction with the steering or
brakes, the vehicle and trailer will sta- bilize.
Be careful when passing other ve- hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
In order to maintain engine braking ef-
ficiency, do not use fifth gear (manual
transmission) or overdrive (automatictransmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over 30 5C [85 5F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the
air conditioning (if in use), pull off the
road and stop in a safe spot. Refer to
If your vehicle overheatsº in Part 4 of this manual.
Always place wheel blocks under both
the vehicle and trailer wheels whenparking. Apply the parking brake firm-
ly. Put the transmission in Pº (auto-
matic) or in first or reverse (manual).
Avoid parking on a slope with a trailer,but if it cannot be avoided, do so only after performing the following: 1. Apply the brakes and hold.
2. Have
someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or Pº (automatic) and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in Pº position (automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de- pressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmission ve- hicles) and slowly pull or back away
from the wheels blocks. Stop and ap- ply your brakes.
4. Have someone retrieve the blocks.

131
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because in-
stability (swaying) of a towing ve-
hicle trailer combination usuallyincreases as the speed increases,
exceeding 72 km/h (45 mph) may cause loss of control.
Slow down and downshift before
descending steep or long down-
hill grades. Do not make sudden downshifts
Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and
result in reduced braking efficien-
cy.
! CAUTION Getting
more kilometers/mileage from a li-
ter/gallon of fuel 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 Chapter
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 drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.
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 lug or overrevving.
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 andbraking. 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 distance
from other vehicles to avoid sudden 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 needless
wear, overheating and poor fuel econ-
omy.
Maintain a moderate speed on highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.
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.
How to save fuel and make
your vehicle last longer, too

132
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps preventcorrosion.
Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For lon-
ger 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 ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, theemission control system operates
properly only when the engine isrunning.!

136
Do not connect the cable to or near any
part that moves when the engine is cranked.
When making the connections, do
not lean over the battery or
accidentally let the jumper cables or
clamps touch anything except the
correct battery terminals or theground. CAUTION
!
5. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelera- tor pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative
cable and then the positive cable.
7. Carefully dispose of the battery cover clothsÐthey may now contain sulfuricacid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked. If your engine stalls while driving

1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
!
If your engine stalls while driving

137
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine running.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
! 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 ve-
hicle. However, note that water drain-ing from the air conditioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken of the coolant 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 quick-
ly 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.
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 underpressure. CAUTION
!
7. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.
If your vehicle overheats

1381. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traf fic. Avoid stopping on the center di-
vider of a highway. Park on a level spotwith firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or reverse (manual).
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
When jacking, be sure to observe
the following to reduce the
possibility of personal injury: Follow jacking instructions.
Use the jack only for lifting your
vehicle during wheel changing.
Never get beneath the vehicle
when supported by a jack.
Do not start or run the engine
while your vehicle is supported bya jack. CAUTION
!
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyondrepair.
1. Get the jack, jack handle and wheel nut wrench.
To prepare yourself for an emergency, you should familiarize yourself with the
use of the jack, each of the tools and their storage locations.
