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 affect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance problems 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.
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 532 and 431.
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.

This meter displays the odometer and two trip meters. To
change the mode indication, push the trip meter reset
knob briefly. Each time you push the knob, the mode
changes in order from the odometer to trip meter A to trip
meter B, then back to the odometer, etc.

meter.

following cases:
The light does not come on even if the parking brake is
applied when the ignition key is in the ONº position.
The light does not come on even if the ignition key is turned
on with the parking brake released.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION

brake is released while the engine is running.
