check engine TOYOTA LAND CRUISER 2006 J100 Owner's Manual

232
The brake system warning light may stay
on for about 60 seconds after the ignition
key is turned to “ON” position. It is nor-
mal if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the brake system warning
light and buzzer. It is normal if the light
turns off and the buzzer stops sounding
after a few seconds.
You may hear a small sound in the engine
compartment after the engine is started or
the brake pedal is depressed repeatedly.
This is a pump pulsating sound of the
brake system, and it is not a malfunction.
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your brake fluid
pressure reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTILOCK BRAKE SYSTEM
(with “ABS” warning light)
The antilock brake system is designed
to automatically help prevent lockup of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti −lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti −lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking perfor-
mance.
The anti −lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti
−lock brake sys-
tem.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle begins to move. This means
that the anti −lock brake system is in the
self check mode, and does not indicate a
malfunction.
When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti −lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the body
and steering wheel. You may also hear
the motor sound in the engine compart-
ment even after the vehicle is stopped.
At the end of the anti −lock brake sys-
tem activation, the brake pedal may
move a little forward.

235
The brake assist system may not work for
about 60 seconds after the engine is
started.
For an explanation of this system’s warn-
ing light, see “Service reminder indicators
and warning buzzers” on page 124.
Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.
Rear step bumper
The rear step bumper is for rear end
protection and easier stepup loading.
To get on the rear step bumper, use the
shaded area between the arrows in the
illustration.
CAUTION
Do not allow more than one person
to get on the rear step bumper at
a time. It is designed for only one
person.
Never drive the vehicle with anyone
on the rear step bumper.

252
Before starting the engine
1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, head restraint height and steering
wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. Once you turn the ignition key to “START”
position and release it, the cranking hold
function continues to crank the engine in
“ON” position until it starts.
The function stops cranking the engine
after about 25 seconds maximum if the
engine has not started yet. When you
crank the engine again, wait a few sec-
onds and restart it.
If you hold the key in “START” position,
the function will keep cranking for about
30 seconds maximum.
(b) Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in “P”. If you need to restart the engine while the
vehicle is moving, put the selector le-
ver in “N”. A starter safety device will
prevent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off.

253
(c) Starting the engine
Before starting the engine, be sure to fol-
low the instructions in “(b) Before crank-
ing”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial 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:
With your foot off the accelerator pedal,
turning the ignition key to “START” posi-
tion, then release it.
Engine should be warmed up by driving,
not in idle. For warming up, drive with
smoothly turning engine until engine cool-
ant temperature is within normal range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” on page
270.NOTICE
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp− edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P”. If necessary, block the
wheels.
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 park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Tips for driving in various
conditions

255

U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following precau-
tions to help minimize the risk of se-
rious personal injury or damage to
your vehicle:
Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving offroad. A
bad bump could jerk the wheel and
injure your hands. Keep both
hands and especially your thumbs
on the outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear
off any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.
When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury.
You are also risking expensive dam-
age to your vehicle’s suspension
and chassis.
NOTICE

If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
 Water entering the engine air intake
will cause severe engine damage.
 Water entering the automatic trans-
mission will cause deterioration in
shift quality, locking up of your
transmission accompanied by ribra-
tion, and ultimately damage.
 Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.

256
Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
 Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the “Scheduled Main-
tenance Guide” or “Owner’s Manual
Supplement”.
Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non −silicate, non −amine, non −nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 316 for details of coolant type
selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about –35 °C (–31 °F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. It tells you how to visually inspect the
battery on page 330. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 315 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer–
they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de −icer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.

257
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“P” and block the front wheels. Do not
use the parking brake, or snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Dinghy towing
30c001a
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.
Trailer towing
Your vehicle is designed primarily as a
passenger−and− load− carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
CAUTION
Vehicles with active height control
suspension system: When disconnect-
ing a trailer, put the vehicle height in
the “LO” (Low) mode and push the
height control switch to turn off the
active height control suspension.
Otherwise, the vehicle height may be
changed in the automatic leveling
function, resulting in an accident. For
details, see “Active height control
suspension” on page 158.

263
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.
