low LEXUS LX470 2006 Owners Manual

STARTING AND DRIVING
296The anti
−lock brake system becomes operative 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 cover, a steel plate at a construction site, joints
in a bridge, etc. on a rainy day tends to activate the anti −lock
brake system.
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 activated, the
following conditions may occur. They do not indicate a
malfunction of the system:
 You may hear the anti− lock brake system operating and feel
the brake pedal pulsating and the vibrations of the vehicle
body and steering wheel. You may also hear the motor
sound in the engine compartment even after the vehicle is
stopped.
 At the end of the anti−lock brake system activation, the
brake pedal may move a little to the forward.
CAUTION
Do not overestimate the antilock brake system:
Although the antilock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the antilock
brake system on.
If tire grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the antilock brake system does not provide
vehicle control.
Antilock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an antilock
brake system, your vehicle may require a longer
stopping distance in the following cases:
 Driving on rough, gravel or snowcovered roads.
 Driving with tire chains installed.

STARTING AND DRIVING
298If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer
as soon as possible to service the vehicle.

The light does not come on when the ignition key is turned
to the “ON” position, or remains on.
 The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the “ABS” warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the antilock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.
Drumindisc type parking brake system
Your vehicle has a drum−in−disc type parking brake system.
This type of brake system needs bedding −down of the brake
shoes periodically or whenever the parking brake shoes
and/or drums are replaced.
Have your Lexus dealer perform the bedding −down.
Brake assist system
When you slam the brakes on, the brake assist system
judges as an emergency stop and provides more powerful
braking for a driver who cannot hold down the brake pedal
firmly.
When you slam the brakes on, more powerful braking will be
applied. At this time, you may hear a sound in the engine
compartment and feel the vibrations of the brake pedal. This
does not indicate a malfunction.
The brake assist system becomes operative 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).
The brake assist system may not work for about 60 seconds
after the engine is started.
For an explanation of this system’s warning light, see “ABS
warning light” on page 58 or 297.

BRAKE PAD WEAR LIMITINDICATORS
31X020d
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have
the brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.
TIRE PRESSURE WARNING SYSTEM
The tire pressure warning system warns you that the tire
inflation pressure is low.
The tire pressure warning syst em is not a substitute for
checking normal t ire inflation pressure. Check the tire inflation
pressure with a tire pressure gauge regularly.
CAUTION
The warning system may not activate immediately if
bursts or sudden air leakage should occur.

Tire pressure warning light
The tire pressure warning light comes on when the ignition
switch is turned to the “ON” position and goes off after a few
seconds. This means the tire pressure warning light is
operating properly. If the tire inflation pressure becomes low,
the light comes on again. In this case, adjusting the tire
inflation pressure will turn off the light after a few minutes. If the
light blinks, the tire pressure warning system is not working
properly.

CAUTION
If the tire pressure warning light comes on, be sure to
observe the following precautions. Failure to do so
could cause loss of vehicle control and result in death
or serious injury.
 Stop your vehicle in a safe place as soon as possible.
Adjust the tire inflation pressure immediately.
 If the tire pressure warning light comes on even after
tire inflation pressure adjustment, it is probable that
you have a flat tire. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired
by the nearest Lexus dealer.
 Avoid abrupt maneuvering and braking. If the vehicle
tires deteriorate, you could lose control of the
steering wheel or the brakes.

STARTING AND DRIVING
301
The tire pressure warning light may turn on due to natural
causes such as natural air l
eaks or tire inflation pressure
changes caused by temperature. In this case, adjusting the
tire inflation pressure will turn off the light.
Pushing the tire pressure warning reset switch should not turn
off the tire pressure warning light. Adjusting the tire inflation
pressure will turn off the light.
The spare tire is also equipped with the tire pressure warning
valve and transmitter. The tire pressure warning light will turn
on if the tire inflation pressure of the spare tire is low. If a tire
goes flat, even though the flat tire is replaced with the spare
tire, the warning light does not turn off. Replace the spare tire
with the repaired tire and adjust the proper tire inflation
pressure. The tire pressure warning light will turn off after a few
minutes.
CAUTION
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label (tire
and load information label). (If your vehicle has tires of
a different size than the size indicated on the vehicle
placard or tire inflation pressure label (tire and load
information label), you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS–tire pressure warning system) that illuminates a
low tire pressure telltale (tire pressure warning light)
when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale (tire pressure warning light) illuminates, you
should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning
system) is not a substitute for proper tire maintenance,
and it is the driver’s responsibility to maintain correct
tire pressure, even if underinflation has not reached
the level to trigger illumination of the TPMS low tire
pressure telltale (tire pressure warning light).

STARTING AND DRIVING
302
Your vehicle has also been equipped with a TPMS
(tire pressure warning system) malfunction
indicator to indicate when the system is not
operating properly. The TPMS (tire pressure
warning system) malfunction indicator is combined
with the low tire pressure telltale (tire pressure
warning light). When the system detects a
malfunction, the telltale w ill flash for approximately
one minute and then remain continuously
illuminated. This sequenc e will continue upon
subsequent vehicle startups as long as the
malfunction exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunction
may occur for a variety of reasons, including the
installation of replacemen t or alternate tires or
wheels on the vehicle th at prevent the TPMS (tire
pressure warning system) from functioning
properly. Always check the TPMS (tire pressure
warning system) malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacemen t and alternate tires and
wheels allow the TPMS (t ire pressure warning
system) to continue to function properly.NOTICE
 Do not use liquid sealants for a flat tire as tire
pressure warning valve and transmitter will be
damaged.
 When the tires must be repaired or replaced, have
them repaired or replaced by your Lexus dealer or an
authorized tire dealer. The tire pressure warning
valves and transmitters will be affected by the
installation or removal of tires.

If the tire pressure warning light blinks...
31x609
If the tire pressure warning light blinks when the ignition
switch is turned to the “ON” position, the tire pressure
warning system is not working properly.
The system will be disabled in the following conditions:
(When the condition becomes normal, the system will work
properly.)

If tires not equipped with tire pressure warning valves and
transmitters are used.
 If the ID code on the tire pressure warning valves and
transmitters is not registered.
 If electronic devices or facilities using similar radio wave
frequencies are nearby.
 If a radio set at similar frequencies is in use in the vehicle. 
If a window tint that affects the radio wave signals is
installed.
 If the tire pressure warning select switch is set to a dif ferent
tire setting.
 If there is a lot of snow or ice on the vehicle, in particular
around the wheels or wheel housings.
 If non− genuine Lexus wheels are used.
 If tire chains are used.
 If the spare tire is in a location subject to poor radio wave
signal reception.
 If the tire inflation pressure is 500 kPa (5.1 kgf/cm2
or bar,
73 psi) or higher.
If the tire pressure warning light blinks frequently when the
ignition switch is turned to the “ON” position, have it checked
by your Lexus dealer.
Even if you use genuine wheels, the tire pressure warning
system may not work properly with some types of tires.
Pushing the tire pressure warning reset switch should not turn
off the tire pressure warning light.

STARTING AND DRIVING
306To initialize the system, perform the following:
1. Park the vehicle in a safe place and turn the ignition switch
to the “OFF” position.
2. Adjust the pressure of all the installed tires to the specified
cold tire inflation pressure level. (See “Tire and wheels” on
page 420.)
3. Turn the ignition switch to the “ON” position.
4. Push and hold the tire pressure warning reset switch until
the tire pressure warning light blinks slowly three times.
5. Wait for a few minutes with the ignition switch “ON”, and
then turn the ignition switch to the “OFF” position.
If you push the tire pressure reset switch while the vehicle is
moving, initialization is not performed.
If you push the tire pressure reset switch accidentally and
initialization is performed, adjust the tire inflation pressure to
the specified level and initialize the system again.
31x609
If the tire pressure warning light does not blink slowly three
times when you push and hold the reset switch, initialization
has failed and the tire pressure warning system may not work
properly. In this case, initialize the system again. If
initialization
cannot be performed, have the system checked at
your Lexus dealer.
CAUTION
Do not push the reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise,
the tire pressure warning light may not come on even if
the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

DRIVING TIPS

OFFROAD VEHICLEPRECAUTIONS
32X001d
This vehicle belongs to the utility vehicle class, which has
higher ground clearance and narrower tread in relation to
the height of its center of gravity to make it capable of
performing in a wide variety of offroad applications.
Specific design characteristics give it a higher center of
gravity than ordinary passenger cars. This vehicle design
feature causes this type of vehicle to be more likely to
rollover. And, utility vehicles have a significantly higher
rollover rate than other types of vehicles. An advantage
of the higher ground clearance is a better view of the road
allowing you to anticipate problems. It is not designed for
cornering at the same speeds as ordinary passenger cars
any more than lowslung sports cars designed to perform
satisfactorily under offroad conditions. Therefore,
sharp turns at excessive speeds may cause rollover.
CAUTION
Always observe the following precautions to help
minimize the risk of serious personal injury or damage
to your vehicle:
 In a rollover crash, an unbelted person is
significantly m ore 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
moving.
 Avoid sharp turns or abrupt maneuvers, if at all
possible. Failure to operate this vehicle correctly
may result in loss of control or vehicle rollover
causing death or serious injury.
 Loading cargo on the roof luggage carrier will make
the center of the vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss
of control or vehicle rollover due to failure to operate
this vehicle correctly.
 Always slow down in gusty crosswinds. Because of
its profile and higher center of gravity, your vehicle is
more sensitive to side winds than an ordinary
passenger car . Slowing down will allow you to have
better control.
