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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

FUEL GAUGE

Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches Eº or the low fuel level warning light
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible.It is not a malfunction even if the needle of the fuel gauge
returns to Eº when the ignition switch is turned to the STARTº
position.
See the inner back cover for fuel capacity and recommended
fuel selection.

ENGINE COOLANT
TEMPERATURE GAUGE

Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating conditions,
such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high speed driving.
Idling for a long period with the air conditioning on in
stop-and-go traffic.
Towing a trailer.It is not a malfunction even if the needle of the engine coolant
temperature gauge returns to Cº when the ignition switch is
turned to the STARTº.

NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant
to keep the temperature of the engine within the
specified operating range.
Do not continue driving with an overheated engine.
See If your vehicle overheatsº on page 443.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

TACHOMETERThe tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine over-revving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
It is not a malfunction even if the needle of the tachometer
returns to the bottom position when the ignition switch is turned
to the STARTº position.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.
