flat tire LEXUS RX330 2006 Owners Manual

IMPORTANT INFORMATION ABOUT YOUR LEXUS
vii
Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident.
Check the tire inflation pressure periodically and be
sure to keep the load limits given in this Owner’s
Manual. For details about tire inflation pressure and
load limits, see pages 570 and 489.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive chemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as fire. Be sure to have the
system of the SRS airbag and seat belt pretensioner removed
and disposed of by a qualified service shop or by your Lexus
dealer before you scrap your vehicle.
Onpavement and offroad driving tips
This vehicle belongs to the utility vehicle class. Utility vehicles
have a significantly higher rollover rate than other types of
vehicles. This vehicle will handle and maneuver differently
from an ordinary passenger car because it is designed for
off−road use also. In addition, this vehicle has a higher ground
clearance and center of gravity than that of an ordinary
passenger car. This vehicle design feature causes this type of
vehicle to be more likely to rollover. Failure to operate this
vehicle correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. Be sure to read
“Off −road vehicle precautions” on page 468 and “Off −road
driving precautions” on page 472.

The front seat belt pretensioner system mainly consists of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating
noise may be heard and a small amount of non −toxic
gas may be released. This does not indicate that a fire is
occurring. This gas is normally harmless.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
 Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instruction may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury. Consult your Lexus dealer
about any repair and modification.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury . Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
“Checking and replacing tires” on page 585.
 Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, which could result in death or
serious injury. For details, see “Roof luggage
carrier” on page 136.

CAUTION
Never depend on the rear view monitor system
entirely when backing up. Always make sure your
intended path is clear.
Use caution just as you would when backing up any
vehicle.
 Never back up while looking only at the screen. The
image on the screen is different from actual
conditions. Depicted distances between objects and
flat surfaces will differ from actual distances. If you
back up while looking only at the screen, you may hit
a vehicle, a person or an object. When backing up, be
sure to check behind and all around the vehicle
visually and with mirrors before proceeding.
 Do not use the system when the back door is not
completely closed.
 If the back of the vehicle is hit, the position and
mounting angle of the camera may change. Be sure
to have the camera’s position and mounting angle
checked at your Lexus dealer.
 If the temperature changes rapidly , such as when hot
water is poured on the vehicle in cold weather, the
system may not operate normally.
 If the camera lens becomes dirty, it cannot transmit
a clear image. If water droplets, snow, or mud adhere
to the lens, rinse with water and wipe with a soft cloth.
If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
 Use your own eyes to confirm the vehicle’s
surroundings, as the displayed image may become
faint or dark, and moving images will be distorted, or
not entirely visible when the outside temperature is
low. When backing up, be sure to check behind and
all around the vehicle visually and with mirror before
proceeding.

2Height control “OFF” indicator light
To turn off the electronically modulated air suspension
with the vehicle stopped, push the height control switch.
The height control “OFF” indicator light comes on and the
vehicle height is fixed in the same mode as was last
selected.
This status is maintained in the system even after the engine
is stopped.
If you push the switch again, the height control “OFF” indicator
light goes out and the electronically modulated air suspension
is turned on. When the vehicle’s speed exceeds 30 km/h (19 mph), the
height control “OFF” indicator light goes out and the
electronically modulated air suspension turns on
automatically.
CAUTION

If you drive through water, such as when crossing
shallow streams, first check the depth of the water
and the firmness of the bottom of the river bed then
put the vehicle height into “HI” mode with the height
select switch and turn off the electronically
modulated air suspension by pushing the height
control switch. Drive your vehicle at 30 km/h (19
mph) or slower and avoid deep water.
 When jacking up, installing tire chains or tying your
vehicle with chains or wires for transportation by a
flat bed, be sure to turn off the electronically
modulated air suspension with the height control
switch and stop the engine. Otherwise, the automatic
leveling function may cause the vehicle’s height to
change, resulting in an unexpected accident.
 If your vehicle must be towed, put the vehicle height
in the “N” mode and turn off the electronically
modulated air suspension. Otherwise, the automatic
leveling function may cause the vehicle’s height to
change, resulting in an unexpected accident.

STARTING AND DRIVING

Brake assist system
If you slam the brakes on such as in an emergency or
apply the brakes more firmly than usual such as when
descending the hill with the designated number of
occupants in the vehicle, the brake assist system
provides more powerful braking.
If you slam the brakes on or apply the brakes more firmly, 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).
For an explanation of this system’s warning light, see “ABS
warning light” on page 81 or 460.
TIRE PRESSURE WARNING SYSTEM
The tire pressure warning system is designed to provide
warning when tire inflation pressure is critically low while
the vehicle is moving. The low tire pressure warning light
comes on to inform you that such low tire pressure may
hamper driving.
This system is not designed to operate when the vehicle is
stopped. Therefore, check the tire inflation pressure regularly.
The recommended cold tire inflation pressure, tire size and the
vehicle capacity weight are on the tire and loading information
label. (For instructions, see “Checking tire inflation pressure”
on page 570.)
Installed tires should be of the specified size. They should be
of the same size and construction. If tires other than the
specified size are used, or if tires of different sizes or
constructions are mixed, the tire pressure warning system will
not function properly.
