IMPORTANT INFORMATION ABOUT YOUR LEXUS
iv
Accessories, spare parts and modification of
your Lexus
A wide variety of non-genuine spare parts and accessories for
Lexus vehicles are currently available in the market. You
should know that Toyota does not warrant these products and
is not responsible for their performance, repair, or
replacement, or for any damage they may cause to, or adverse
effect they may have on, your Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus
products. Modification with non- genuine Lexus products
could af fect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance pro blems resulting from the modification may not
be covered under warranty.
If you install any Genuine Accessories such as a bull-bar,
winch, etc., consult your Lexus dealer.
Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference- Causing
Equipment Standard.
Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your
vehicle could affect electronic systems such as the multiport
fuel injection system/sequential multiport fuel injection system,
cruise control system, anti-lock brake system, SRS airbag
system and seat belt pretensioner system, be sure to check
with your Lexus dealer for precautionary measures or special
instructions regarding installation.
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 579 and 473.
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 a fire. Be sure to have the
systems 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.

(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to ONº
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to ONº position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to ONº position. The light will remain on
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to the ACCº or LOCKº position with
the odometer reading shown. (For details, see Odometer and
trip meterº on page 61.)
2. Turn the ignition key to the ONº position while holding down
the trip meter reset knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second. If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.(o) Low Tire Pressure Warning Light
This light warns that the tire pressure of one or more of your
tires
(including the spare tire) is low. The light comes on when
the ignition key is turned to the ONº position. It goes off after
a few seconds. This indicates that the tire pressure warning
system is functioning properly.
If the warning light comes on, stop your vehicle in a safe place
as soon as possible and check that the inflation pressure of all
tires (including the spare tire) is as specified on the tire and
loading information label. (See Checking tire inflation
pressureº on page 579.) The light should go off a few minutes
after the tire pressure is adjusted.
If the warning light blinks, the tire pressure warning system
may be malfunctioning. Contact your Lexus dealer.
For details, see Tire pressure warning systemº on page 434.
(p) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.

STARTING AND DRIVING
405
REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear view
mirror.
To display the rear view image on the screen, place the
selector lever in the Rº position when the ignition switch
is in the ONº position.
If you move the selector lever out of the Rº position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
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 w hile 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.

STARTING AND DRIVING
434
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 lightº on page 67.
Drum-in-disc 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.
TIRE PRESSURE WARNING SYSTEM
The tire pressure warning system is designed to provide
warning when tire inflation pressure of one or more of
your tires (including the spare tire) is low. The low tire
pressure warning light comes on to inform you that low
tire inflation pressure may hamper driving.

Low tire pressure warning light
This light comes on when the ignition key is turned to the ONº
position. It goes off after a few seconds. This indicates that the
tire pressure warning system is functioning properly.

STARTING AND DRIVING
435
If the low tire pressure warning light comes on or blinks,
do the following.
If the warning light comes on:
Stop your vehicle in a safe place as soon as possible and
check that the inflation pressure of all tires (including the
spare tire) is as specified on the tire and loading
information
label. (See Checking tire inflation pressureº
on page 579.) If the warning light comes on even after tire
inflation pressure adjustment, you may have a flat tire. If
you have a flat tire, replace it with the spare tire. For
details, see If you have a flat tireº on page 487.
The warning light goes off a few minutes after air is put into the
deflated tire.
This warning light may turn on due to natural causes such as
natural air leaks or tire pressure changes caused by
temperature. In this case, adjusting the tire pressure will turn
off the warning light.
CAUTION
When the low tire pressure warning light comes on,
observe the following instructions:
 Depending on the conditions, reduce to an
appropriate speed as soon as possible.
 Adjust the tire pressure to the specified level as soon
as possible.
 Avoid abrupt steering wheel maneuvering and
braking. Tire deterioration may reduce steering
wheel control and brake effectiveness. This may lead
to serious injury or death.
 The tire pressure warning system may not activate
immediately if sudden bursts of air leakage occur.
