IMPORTANT INFORMATION ABOUT YOUR LEXUS
v
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 problems resulting from the modification may not
be covered under warranty.
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 twoway 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, dynamic radar/laser 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 468 and 393.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive c hemicals. 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
system 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.

key is placed near the spare tire or at the edge of the
trunk, or if the key is in a metallic bag, the trunk lid
might not be unlocked.
 If you accidentally lock a smart key in the trunk, be
aware that anyone can unlock the trunk by pushing
the trunk button.
 Even when the smart key is outside the trunk, an
alarm still might be activated if the key is near the
trunk. However, if you have the key, there is no
problem.

STARTING AND DRIVING

TIRE PRESSURE WARNINGSYSTEM
The tire pressure warning system is designed to provide
warning using a message in the multiinformation
display, master warning light and warning tone when tire
inflation pressure is critically low while driving. This
message appears to inform you that such low tire
pressure may hamper driving.
As this system is not designed to operate when the vehicle is
stopped, check the tire inflation pressure regularly. The
recommended cold tire inflation pressure, tire size and the
vehicle capacity weight are on the tire and loading information
label. (For instructions, see “Checking tire inflation pressure”
on page 468.)
Installed tires should be of the specified size. They should be
of the same size and construction. If tires other than the
specified size are used, or if tires of different sizes or
constructions are mixed, the tire pressure warning system will
not function properly.
Low tire pressure warning message
w264
When the low tire inflation pressure is detected while
driving, the master warning light comes on, the above
message appears and a warning tone sounds.
If the above message appears and adjust the tire inflation
pressure to the specified level as soon as possible. Push the
tire pressure warning system reset switch for a few seconds
and make sure the warning message goes off. If the message
still remains on, have your vehicle checked by your Lexus
dealer as soon as possible.
The tire pressure warning system does not function
properly under certain circumstances. In the following
cases, the low tire pressure warning may not turn on even
if the tire inflation pressure is low, or it may turn on when
the tire inflation pressure is actually normal.
 A compact spare tire, snow tires, or tire chains are used.
 The tire inflation pressure is excessively higher than
specified, or tire inflation pressure suddenly drops due to
bursting or other causes.
 You are driving on slippery road surfaces such as rough or
frozen roads.
 You are driving under 30 km/h (19 mph) or above 100 km/h
(62 mph) for less than 5 minutes.
 The tires differ in tread pattern or manufacturer.
 The tires are not the specified size.

5. After making sure no one is in the vehicle, raise it
high enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance
when putting on the spare tire than when removing the
flat tire.
To raise the vehicle, insert the jack handle into the jack
(it is a loose fit) and turn it clockwise. As the jack touches
the vehicle and begins to lift, double −check that it is
properly positioned.
CAUTION
Never get under the vehicle when the vehicle is
supported by the jack alone.

CHASSIS
469
You should check the tire inflation pressures every two
weeks, or at least once a month. And do not forget the
spare! The pressure for the spare tire should be the
same as that for the standard tire. (See pages 463
through 465.)
The following instructions for checking tire inflation
pressure should be observed:
The pressure should be checked only when the
tires are cold. If your vehicle has been parked for at
least 3 hours and has not been driven for more than
1.5 km or 1 mile since, you will get an accurate cold
tire inflation pressure reading.
 Always use a tire pressure gauge. The appearance
of the tire can be misleading. Besides, tire inflation
pressures that are even just a few pounds off can
degrade ride and handling.
 Do not bleed or reduce tire inflation pressure after
driving. It is normal for the tire inflation pressure to
be higher after driving.
 Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located so
that the vehicle is balanced. Inspection and adjustment procedure

1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of app lying too much air, press the center
of the valve and release the air to adjust.
5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to the
valve and check for leakage.

CHECKING AND REPLACING TIRES
When to replace your tires
62L026
 1New tread 2Tread wear indicator
3Worn tread
Replace the tires when the tread wear indicators
show. The location of the tread wear indicators is
shown by the “TWI” or “
Δ” marks, etc., molded on
the sidewall of each tire.
The tires on your Lexus have built −in tread wear
indicators to help you know when the tires need
replacement. When the tread depth wears to 1.6 mm
(0.06 in.) or less, the indicators will appear. If you can
see the indicators in two or more adjacent grooves, the
tire should be replaced. The effectiveness of snow tires is lost if the tread
wears down below 4 mm (0.16 in.).
If you have tire damage such as cuts, splits, cracks
deep enough to expose the fabric, or bulges
indicating internal damage, the tire should be
replaced.
If a tire often goes flat or cannot be properly repaired due
to the size or location of a cut or other damage, it should
be replaced. If you are not sure, consult with your Lexus
dealer.
If air loss occurs while driving, do not continue driving.
Driving
even a short distance can damage a tire beyond
repair.
Any tires which are over 6 years old must be
checked by a qualified technician even if damage is
not obvious.
Tires deteriorate with age even if they have never or
seldom been used.
This applies also to the spare tire and tires stored for
future use.
