CAUTION
The total trailer weight (trailer
weight plus its cargo load) must
not exceed the following. Exceed-
ing this weight is dangerous. If
towing a trailer over 907 kg (2000lb.), it is necessary to use a sway
control device with a sufficient ca-
pacity.
Two-wheel drive models
3RZ-FE engine 1814 kg (4000 lb.)
5VZ-FE engine 2359 kg (5200 lb.)
Four wheel drive models 2268 kg (5000 lb.)
The gross combination weight
(sum of your vehicle weight plus
its load and the total trailer
weight) must not exceed the fol- lowing.
Two-wheel drive models
3RZ-FE engine 3629 kg (8000 lb.)
5VZ-FE engine 4173 kg (9200 lb.)
Four-wheel drive models
4309 kg (9500 lb.)!
The gross vehicle weight must not
exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the
Certification Label. The gross ve-
hicle weight is the sum of weights
of the unloaded vehicle, driver,
passengers, luggage, hitch and
trailer tongue load. It also includes
the weight of any special equip-
ment installed on your vehicle.
The load on either the front or rearaxle resulting from distribution of
the gross vehicle weight on both axles must not exceed the Gross
Axle Weight Rating (GAWR) listed on the Certification Label.The trailer cargo load should be
distributed so that the t ongue load
is 9 to 11% of the total trailer
weight, not exceeding the exceed-
ing the maximum of the following:
Two-wheel drive models 3RZ-FE engines 181 kg (400 lb.)
5VZ-FE engine 236 kg (520 lb.)
Four wheel drive models
226 kg (500 lb.)

128
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.

129
TRAILER LIGHTS
Trailer lights must comply with federal,
state/provincial and local regulations. See your local recreational vehicle
dealer or rental agency for the correcttype of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age your vehicle's electrical system
and cause a malfunction of your lights.
BREAK-IN SCHEDULE Toyota recommends that you do not
tow a trailer with a new vehicle or a ve-
hicle with any new power train compo-
nent (engine, transmission, differen- tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE If you tow a trailer, your vehicle will re-
quire more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Own-
er 's Manual Supplement/MaintenanceScheduleº.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving. PRE-T OWING SAFETY CHECK
Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose-up or nose-down
condition, and check for improper
tongue load, overload, worn suspen-
sion or other possible causes.
Make sure the trailer cargo is securely
loaded so that it cannot shift.
Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulation. If not,
install the rear view mirrors required
for towing purpose.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-ing. The three main causes of vehicle
trailer accidents are driver error, ex-
cessive speed and improper trailer
loading. Keep these in mind when tow-
ing: Before starting out, check operation of
the lights and all vehicle-trailer con-
nections. After driving a short dis-
tance, stop and recheck the lights and
connections. Before actually towing a
trailer, practice turning, stopping and
backing with a trailer in an area away
from traffic until you learn the feel.
Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of the steering wheel and move your hand to
the left to move the trailer to the left. Move your hand to the right to move
the trailer to the right. (This procedureis generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at a time,
avoiding sharp or prolonged turning. Have someone guide you when back-
ing to reduce the risk of an accident.
Because stopping distance may be in-
creased, vehicle-to-vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accelera-tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.

130
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.!

Part 4If your vehicle will not startÐ
(a) Simple checks
133
IN CASE OF AN EMERGENCY
If your vehicle will not start
If your engine stalls while driving
If your vehicle overheats

If you have a flat tire
If your vehicle needs to be towed
If you lose your keys
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery is
discharged. You may try jump starting.
See (c) Jump startingº for further in- structions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalytic converter may overheat andbecome a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors are tight. (For example, connections at the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See (b) Starting a flooded
engineº for further instructions.

134If the engine will not start, your engine
may be flooded because of repeated cranking.
Turn the key to STARTº with the acceler-
ator pedal held down. Keep the key and accelerator pedal so for 15 seconds and
release
them. Then try starting the engine
with your foot off the accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait afew minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 sec- onds at a time. This may overheat
the starter and wiring systems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
If you are unsure about how to follow this procedure, we strongly recommend that you seek the help of a competent me-
chanic or towing service.
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses
when jump starting, and avoid
spilling acid on your skin, cloth-
ing, or vehicle.
If you should accidentally get acid
on yourself or in your eyes, re- move any contaminated clothing
and flush the affected area with water for at least 15 minutes. Then
get immediate medical attention. If
possible, continue to apply water
with a sponge or cloth while en
route to the medical office. CAUTION
!

The gas normally produced by a battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and
do not smoke or light a match
while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless
you are sure that the booster batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. T urn off all un-
necessary lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged bat-
teries. Lay a cloth over the open vents
on the batteries. (This helps reduce
the explosion hazard, personal injuries
and burns.)
(b) Starting a flooded engine (c) Jump starting

135
3. If the engine in the vehicle with the
booster battery is not running, start it
and let it run for a few minutes. During
jump starting, run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.
4. Make the cable connection in the ordera, b, c, d.
a. Connect the clamp of the positive (red)
jumper cable to the positive (+) termi-
nal on the discharged battery.
b. Connect the clamp at the other end of the positive (red) jumper cable to the
positive (+) terminal on the booster
battery.c. Connect the clamp of the negative(black) jumper cable to the negative
(-) terminal on the booster battery.
d. Connect the clamp at the other end of the negative (black) jumper cable to a
solid, stationary, unpainted, metallic
point of the ve hicle with the discharged
battery.
The recommended connecting points are
shown in the following illustration:

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
0
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
