ABOUT YOUR LEXUS
Occupant restraint systems
Lexus encourages you and your family to take the time to read
Section 1-6 of this Owner's Manual carefully. In terms of
helping you understand how you can receive the maximum
benefit of the occupant restraint systems this vehicle provides,
Section 1-6 of this Owner's Manual is the most important
Section for you and your family to read.
Section 1-6 describes the function and operation concerning
seats, seat belts, SRS airbags and child restraint systems of
this vehicle and some potential hazards you should be aware
of. These systems work together along with the overall
structure of this vehicle in order to provide occupant restraint
in the event of a crash. The effect of each system is enhanced
when it is used properly and together with other systems. No
single occupant restraint system can, by itself, provide you or
your family with the equal level of restraint which these
systems can provide when used together. That is why it is
important for you and your family to understand the purpose
and proper use of each of these systems and how they relate
to each other.The purpose of all occupant restraint systems is to help reduce
the possibility of death or serious injury in the event of a
collision. None of these systems, either individually or
together, can ensure that there is no injury in the event of
collision. However, the more you know about these systems
and how to use them properly, the greater your chances
become of surviving an accident without death or serious
injury.
Seat belts provide the primary restraint to all occupants of the
vehicle, and every occupant of the vehicle should wear seat
belts properly at all times. Children should always be secured
in child restraint systems that are appropriate for their age and
size. SRS (Supplemental Restraint System) airbags are, as
their names imply, designed to work with, and be supplemental
to, seat belts and are not substitutes for them. SRS airbags
can be very effective in reducing the risk of head and chest
injuries by preventing contact of the head and chest with
interior portions of the vehicle.
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
makes the SRS airbags themselves potential sources of injury
if an occupant is too close to an airbag, or if an object or some
part of his or her body has been placed between the occupant
and the airbag at the time of deployment. This is just one
example of how the instructions in Section 1-6 of this Owner's
Manual will help ensure proper use of the occupant restraint
systems, and increase the safety they can provide to you and
your family in the event of an accident.
Lexus recommends you to read the provisions in Section 1-6
carefully and refer to them from time to time during your time
of ownership of this vehicle.

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.

KEYS AND DOORS
22
CAUTION
Do not pull the inside handle of the front doors while
driving. The doors will open and an accident may occur.
Lexus strongly recommends that all children be placed
in the rear seat of the vehicle.
Closing the door with the lock button pushed in will also lock the
door. Be careful not to lock your keys in the vehicle. Doors
cannot be locked when either front door is open and the key is
in the ignition.
CAUTION
Before driving, make sure the doors are closed and
locked, especially when small children are in the
vehicle. Along with the proper use of seat belts, locking
the doors helps prevent the driver and passengers from
being thrown out from the vehicle during an accident.
It also helps prevent the doors from being opened
unintentionally.
Locking with power door lock switch

1Lock2Unlock
To lock all the side doors and back door simultaneously,
push the power door lock switch down on the front side.
Pushing down on the rear side will unlock them.
The same switch is also located on the front passenger's side.
If you do any of the following, no door can be unlocked with the
power door lock switch.
Lock all the doors with the key or wireless remote control
when all the doors are closed.
Open the driver's door or front passenger's door and move
the inside lock buttons of both front doors to the lock

ODOMETER AND TRIP METER

Trip meter reset knob
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.
The odometer records the total distance the vehicle has
been driven. The twin trip meter records two different
distances independently.
For example, you can use one meter to calculate the fuel
economy and the other to measure the distance on each trip.
To set the A trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

When you drive for about 8000 km (5000 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 12000 km (7500 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.
