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.

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.

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
!
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

159
Tire surface and wheel nuts Check the tires carefully
for cuts, damage
or excessive wear. See Chapter 7-2 for
additional information. When checking the tires, make sure no nuts are missing,
and check the nuts for looseness. T ighten
them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7-2 for additional in- formation.
Fluid leaks Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has been
parked for a while. If you smell fuel fumes
or notice any leak, have the cause found
and corrected immediately. Doors and engine hood Check that all doors including tailgate op- erate smoothly and all latches lock se-
curely. M ake sure the engine hood secon-
dary latch secures the hood from opening
when the primary latch is released. INSIDE THE VEHICLE Items listed below should be checked
regularly, e.g. while performing peri-
odic services, cleaning the vehicle,etc. LightsMake sure the headlights, stop lights, tail lights, turn signal lights, and other lights are all working. Check headlight aim. Service reminder indicators and
warn-
ing buzzersCheck that all service reminder indicators
and warning buzzers function properly. Steering wheel
Be alert for changes in steering condition, such as hard steering or strange noise. Seats Check that all seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly and that all latches lock securely
in any position. Check that the head re-
straints move up and down smoothly and
that the locks hold securely in any latched
position. For folding-down seatback
(bench seat), check that the latches lock
securely. Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure that the
belt webbing is not cut, frayed, worn ordamaged.
Accelerator pedal Check the pedal for smooth operation and
uneven pedal effort or catching. Clutch pedal Check the pedal for smooth operation. Brake pedal Check
the pedal for smooth operation and
that the pedal has the proper clearance. Check the brake booster function. Brakes
At a safe place, check that the brakes do not pull to one side when applied. Parking brake Check that the lever has the proper travel and that, on a safe incline, your vehicle is
held securely with only the parking brake applied.
Automatic transmission Parkº mech-
anism
On a safe incline, check that your vehicle is held securely with the selector lever in Pº position and all brakes released.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time, e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.

Aluminum wheel precautions
With the engine at operating tempera- ture and turned off, check the oil level
on the dipstick.
1. To get a true reading, the vehicle
should be on a level spot. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick 'push it in as far
as it will go, or the reading will not be correct.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.!
If the oil level is below or only slightly
above the low level line, add engine oil
of the same type as already in the en- gine. Remove the oil filter cap and add engine oil in small quantities at a time, checkingthe dipstick.
The approximate quantity of oil needed to
fill between the low level line and the full
level on the dipstick is indicated below for reference. When the level reaches within the correct range, install the filler cap hand-tight.
Oil quantity, L (qt., Imp. qt.):
3RZ-FE engine 1.5 (1.6, 1.3) 5VZ-FE engineTwo-wheel drive models 1.5 (1.6, 1.3)
Four-wheel drive models 1.4 (1.5, 1.2)

174
To check the fluid level, simply look at
the see through reservoir. The level
should be between the MAXº and
MINº lines on the reservoir. It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled. If the reservoir needs frequent refilling, it may indicate a serious mechanical prob- lem. If the level is low, add SAE J1703 or
FMVSS No. 116 DOT 3 brake fluid to the
brake reservoir. Remove and replace the reservoir cover by hand. Fill the brake fluid to the dotted
line.
This brings the fluid to the correct lev-
el when you put the cover back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture
from the air, and excess moisture cancause a dangerous loss of braking.CAUTION
Take care when filling the reservoir
because brake fluid can harm your
eyes and damage painted surfaces.
If fluid gets in your eyes, flush your
eyes with clean water.!
If you spill the fluid, be sure to wash it off with water to prevent it from
damaging the parts or paint.
NOTICE
Check the fluid level on the dipstick. If
necessary, add automatic transmis-
sion fluid DEXRON [
-II or -III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little more
in frigid temperatures), the fluid is hot (40 C ' 80 C or 104 F ' 175 F). You
may also check the level when the fluid is
cold (about room temperature, 0 C '
40 C or 32 F ' 104 F) if the engine has
not been run for about five hours.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the filler cap by turning it counterclockwise and wipe the dip-
stick clean.

NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See Fuse locationsº in Chapter 7-1 for
locations of the fuses.
Turn the ignition switch and inopera-
tive component off. Pull a suspected
fuse straight out and check it.
Determine wh ich fuse may be causing the
problem. The lid of the fuse box shows the name of the circuit for each fuse. See Part 8 of this manual for the functions con-
trolled by each circuit.
Type A fuses can be pulled out by the pull-
out tool.
