For your information
Main Owners Manual
Please note that this manual applies to all models and explains all equipment, including options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. However, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustration may differ from
your vehicle in terms of color and equipment.
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 only be modified using 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.
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.
12
Scrapping of your Lexus
CAUTION
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 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.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
■ General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that will hurt or kill you, your occupants or others.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■ When children are in the vehicle
Never leave children unattended in the vehicle.
When left unattended, children may be able to start the vehicle or shift the vehicle
into neutral. There is also a danger that children may injure themselves by playing
with the cigarette lighter, the windows, the retractable hardtop, or other features of
the vehicle. In addition, heat build-up or extremely cold temperatures inside the
vehicle can be fatal to children.

■ The rear seat contact avoidance function
If you push back the seat backward when the seatback reclined too far backward,
the seat will adjust the seatback angle forward.
If you recline the seatback too far backward when the seat is in the pushed back
position, the seat will adjust the seat position forward.
■ After first reconnecting the battery
The rear seat contact avoidance function does not work. When you push back the
seat or recline the seatback backward, a buzzer sounds to warn that the rear seat
may interfere with the seatback movement. The following procedure must be performed.
Move the seat position control switch forward until a beeping sound is
emitted.
Move the seatback angle switch forward until a beeping sound is emitted.

Before driving
■ Reclining adjustment
Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of sliding under the lap belt.
If the seat is too reclined during an accident, the lap belt may slide past the hips and
apply restraint forces directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk of death or serious injury.
■ After adjusting or returning the seatback
Push and pull the seatback to confirm that it is securely locked.
■ While the vehicle is moving
Never operate the seatback lock release levers.
29
1-3. Adjustable components (seats, mirrors, steering wheel)
The vehicle will memorize the positions of the driver’s seat, the tilt-and-telescopic steering column and outside rear view mirrors.
Two different driving position profiles can be entered into the computer’s
memory.
The same buttons are found on the front passenger’s side, allowing the position of the front passenger’s seat to be memorized.
■ Setting the driving position
With the transmission selector lever in the “P” position, turn the
engine switch to the “ON” position.
Adjust the driver’s seat, tilt and telescopic steering column, and
outside rear view mirrors to the desired positions.
While pushing the “SET” button,
push button “1” or “2” until the signal beeps.
By repeating these three steps and
pressing the other button, the driving position for another driver can
be recorded.
