TRAILER LIGHTS
Your vehicle is equipped with a wire
harness stored in the rear end under
body. Your vehicle is fitted with a sock-
et for trailer lights under the rear
bumper. Use either of them to connect
and operate the trailer lights. However,
the trailer lights must comply with fed-
eral, state/provincial and local regula-
tions. See your local recreational ve-
hicle dealer or rental agency for the
correct type of wiring and relays for
your trailer. Check for correct operation
of the turn signals and stop lights each
time you hitch up. Direct splicing may
damage your vehicle’s electrical system
and cause a malfunction of your lights.BREAKIN SCHEDULE
Toyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (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
require more frequent maintenance due
to the additional load. For this
information, please refer to the
scheduled maintenance information in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
CONNECTING A TRAILER (models with
active height control suspension only)
Stop your vehicle and a trailer in line and
perform the following: 1. Put the active height control suspen- sion in the “LO” (low) mode. Turn the
ignition switch off or push the height
control switch to turn off the active
height control suspension.
2. Connect a trailer. 3. Turn the ignition switch on or push the
height control switch to turn on the
active height control suspension. Select
the “N” (normal) mode with the height
select switch.
When a vehicle loaded with four occu-
pants tows a trailer of about 1800 kg
(4000 lb.) with more than about 180 kg
(400 lb.) tongue load, the normal mode
may not be selected with the height con-
trol indicator “LO”. However, there is no
problem to continue normal driving. Drive
with sufficient care because of large load.
DISCONNECTING A TRAILER (models
with active height control suspension
only)
Stop your vehicle and a trailer in line and
perform the following:
1. Put the active height control suspen- sion in the “LO” mode. (Make sure the
vehicle height is in the “LO” mode by
pushing the height select switch on the
“
”side.)
2. Turn the ignition switch off or push the height control switch to turn off the
active height control suspension.
3. Set the supporting leg of a trailer on the ground and raise the hitch by 100
mm (4 in.).

Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
engine” on page 252 and that you have
sufficient fuel. Also check whether the
other keys will start the engine. If they
work, your key may be broken. Have the
key checked at your Toyota dealer. If
none of your keys work, there may be a
malfunction in the immobilizer system. Call
your Toyota dealer. (See “Keys” on page
10.)If the engine is not turning over or is
turning over too slowly—
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 start-
ing. See “(c) Jump starting” 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 pushstart the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the threeway catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start— 1. The engine may be flooded because of repeated cranking. See “(b) Starting a
flooded engine” for further instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop.
If your vehicle will not start—
(a) Simple checks

273
Connecting point
Do not connect the cable to or near any
part that moves when the engine is
cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Charge the discharged battery with thejumper cables connected for approxi-
mately 5 minutes. At this time, run the
engine in the vehicle with the booster
battery at about 2000 rpm with the ac-
celerator pedal lightly depressed.
6. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
7. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
8. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
9. 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 at your Toyota
dealer. If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If the another attempt is not successful,
the battery may be depleted. Have it
checked at your Toyota dealer.

275
3. Visually check to see if the enginedrive 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” on page 317.
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 temperaturehas 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.
If you have a flat tire—
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”.
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.

Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See “Engine exhaust cautions” on
page 229.)
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail
lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and warning
buzzers
Check 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 front seat controls such as
seat adjusters, seatback recliner, etc. op-
erate smoothly and that all latches lock
securely in any position. Check that the
head restraint move up and down smooth-
ly and that the locks hold securely in any
latched position. For folding
−down rear
seatbacks, swing −up rear seat cushions
and detachable third seats, 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 the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
In 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 “Park” mecha-
nism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your
vehicle is held securely with the selector
lever in “P” position and all brakes re-
leased.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
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 and back door oper-
ate smoothly and all latches lock securely.
Make sure the engine hood secondary
latch secures the hood from opening when
the primary latch is released.

314
Checking the engine oil level
Low levelFull level
Add oil Too full O.K.
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a correct reading, the vehicle should be on level ground. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it clean.3. Standing up on the left side of thevehicle, reinsert the dipstick in the di-
rection so that the “ENGINE OIL” on
top should be read correctly and 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 while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding the oil.
The approximate quantity of oil needed to
raise the level between low and full on the
dipstick is indicated as follows:
1.5 L (1.6 qt., 1.3 Imp.qt.)
For the engine oil capacity, see “Service
specifications” on page 341.
When the level reaches within the correct
range, install the filler cap hand− tight.
NOTICE
Be careful not to spill engine oil on
the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.

318
Under the unloaded condition, check
the suspension fluid AHC in the follow-
ing way.1. Start the engine and put the vehicle height in the “LO” (Low) mode and
then “N” (Normal) mode.
2. Turn off the ignition switch about 30 seconds after the “N” (Normal) mode
indicator light comes on.
3. Make sure the fluid level is between “MAX” and “MIN”.
If the fluid level is lower than “MIN”, have
suspension fluid AHC f illed by your Toyota
dealer.
NOTICE
Only use the Suspension fluid AHC
for the active height control suspen-
sion. If you fill other fluids such as
brake fluid, automatic transmission
fluid, power steering fluid, engine oil,
etc., the active height control suspen-
sion could be damaged.
Checking brake fluid
To check the fluid level, simply look at
the seethrough reservoir. The level
should be between the “MAX” and
“MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear or
when the fluid level in the accumulator is
high.
If the reservoir needs frequent refueling,
it may indicate a serious mechanical prob-
lem.

ries are off before performing main-
tenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“–” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
If the battery terminal is disconnected
or the battery is run down, the moon
roof may not operate automatically and
the jam protection function will not operate
correctly after you reconnect, replace or
recharge the battery with the moon roof
slide −opened or tilted up. In any of these
cases, you should return the moon roof to
normal. To return the moon roof to normal,
see “Electric moon roof” on page 31.

ducing hydrogen gas.
Therefore, before recharging:1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
