How to save fuel and make your
vehicle last longer, too
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 inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
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 prevent the start-
er from operating if the clutch pedal is not fully depressed.
Automatic transmission: Put the selec-
tor lever in Pº. If you need to restart the
engine while the vehicle is moving, put the
selector lever in Nº. A starter safety de-vice 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.

140Before starting the engine, be sure to fol-
low the instructions in (a) Before crank- ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential 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. With your foot off the accelerator ped- al, crank the engine by turning the key to
STARTº. Release it when the enginestarts.
2. After
the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine 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 startÐ
See If your vehicle will not startº in Part 4.
NOTICE
Do not crank for more than 15 sec-
onds 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 theengine checked immediately.
Always slow down in gusty cross- winds. This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid drivingonto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.

Four-wheel drive modelsÐToyota
recommends not using four-wheel
drive on dry hard-surfaced roads, be-
cause four-wheel driving will causeunnecessary noise and wear, and poor
fuel economy.
Four-wheel drive modelsÐIn cold
temperatures, noise may occur when
driving in two-wheel drive before the
transfer is warmed up. Therefore, first
drive in four-wheel drive until the
transfer is warmed up.
CAUTION!
Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat- tended while the engine is run-ning.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat
and not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could cause the vehicle to spin or skid.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure to consult a tire dealer to de-
termine whether the tires on your
vehicle are high-speed capability
tires or not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking
brake will not hold the vehicle se-
curely. When driving your vehicle off-road,
please observe the following precautions
to ensure your driving enjoyment and to
help prevent the closure of areas to off-
road vehicles.
a. Drive your vehicle only in areas where
off-road vehicles are permitted to travel.
b. Respect private property. Get owner's
permission before entering private prop-
erty.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When con- ditions are wet, driving techniques should
be changed or travel delayed to prevent
damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consultthe following organizations.

The trailer cargo load should be
distributed so t hat the tongue load
is 9 to 11% of the total trailer
weight, not exceeding the maxi-
mum of the following. 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 re-
maining 40 % in the rear.
3RZ-FE engine158 kg (350 lb.)
5VZ-FE engine 226 kg (500 lb.) 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.
The hitch ball and king pin should havea light coat of grease.
Toyota recommends removing the hitch when not towing to prevent injury
and/or damage due to the hitch in
event of a rear end collision. After re-moval of the hitch, seal the installation
area to prevent entry of exhaust fumes
and mud.
NOTICE
Do not use an axle-mounting hitch as it may cause damage to the axle
housing, wheel bearings, wheelsand or tires.
BRAKES AND SAFETY CHAINS Toyota recommends trailers with
brakes that conform to any applica-
ble federal and state/provincial reg- ulations.
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain shouldcross under the trailer tongue to
prevent the tongue from dropping
to the ground in case it becomes
damaged or separated. For correct
safety chain procedures, follow the
hitch or trailer manufacturer's rec-ommendations.
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.

146TIRES
Ensure that your vehicle's tires are
properly inflated. See Chapter 7-2 forinstructions.
The trailer tires should be inflated to
the pressure recommended by the
trailer manufacturer in respect to the
total trailer weight.
TRAILER LIGHTS Trailer lights must comply with federal,
state/provincial and local regulations. See your local recreational vehicle
dealer or rental agency for the correct type 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/Maintenance Scheduleº.
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 thesteering 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.

149

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 distance
from other vehicles to avoid suddenbraking. This will also reduce wear onyour 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 properalignment. 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 corrosion.
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
without the engine running. Also,
the emission control system oper-
ates properly only when the engine
is running.

Part 4If your vehicle will not startÐ
(a) Simple checks
151
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 cannot shift automatic transmission selector lever
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 dis-
charged. You may try jump starting. See
(c) Jump startingº for further instructions.
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 ve- hicle. It may damage the vehicle or
cause a collision when the enginestarts. Also the three-way catalytic converter may overheat and be-come 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, connectors at thespark plugs)
2. If the connectors are O.K., the engine
may be flooded because of repeatedcranking. See (b) Starting a flooded en-
gineº for further instructions.

152If the engine will not start, your engine
may be flooded because of repeated cranking.
If this happens, turn the key to STARTº with the accelerator 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 a few 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 15 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.
(b) Starting a flooded engine (c) Jump starting

153
JUMP STARTING PROCEDURE
1. If the booster battery is installed in
another vehicle, make sure the vehicles
are not touching. Turn off all unnecessary
lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged batter- ies.
Lay a cloth over the open vents on the
batteries. (This helps reduce the explo-
sion hazard, personal injuries and burns.)
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 de- pressed.
4. Make the cable connections in the or- der a, b, c, d.
a. Connect a positive (red) jumper
cable to the positive (+) terminal on the
discharged battery.
b. Connect the clamp at the other end
of the positive (red) cable to the posi- tive (+) terminal on the booster battery.c. Connect a negative (black) cable to
the negative (-) terminal on the boost-
er battery.
d. Connect the clamp at the other end
of the negative (black) cable to a solid,
stationary, unpainted, metallic point ofthe vehicle with the discharged bat-
tery.
The recommended connecting points
are shown in the following illustrations:

154
Connecting point for 5VZ-FE engine
Connecting point for 3RZ-FE engineDo not connect it to or near any part that moves when the engine is cranked.
NOTICE
When making the connections, do not lean over the battery or acciden-
tally let the jumper cables or clamps touch anything except the correctbattery terminals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm for several minutes with the accelerator ped-
al 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 sulfuric acid.
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
