3887-2. Steps to take in an emergency
Remove the cover inside the trunk and
pull the lever.
If you lose your keys
New genuine mechanical keys can
be made by your Lexus dealer using
another mechanical key and the
key number stamped on your key
number plate. Keep the plate in a
safe place such as your wallet, not in
the vehicle.
NOTICE
QWhen an electronic key is lost
If the electronic key remains lost, the risk
of vehicle theft increases significantly.
Visit your Lexus dealer immediately with
all remaining electr onic keys and the
card key (if equipped) that were pro-
vided with your vehicle.
If the fuel filler door cannot
be opened
If the fuel filler door opener switch
cannot be operated, contact your
Lexus dealer to service the vehicle.
In case where refueling is urgently
necessary, the following proce-
dure can be used to open the fuel
filler door.
Opening the fuel filler door
NOTICE
QWhen opening the fuel filler door
manually
ODo not open the fuel filler door manu-
ally except in an emergency. Fuel may
overflow.
OUsing the lever to open the fuel filler
door may not allow for an adequate
reduction in fuel ta nk pressure before
refueling. To prevent fuel from spilling
out, turn the cap slowly when remov-
ing it.
ODuring refueling, fuel may spill out
from the filler opening due to air being
discharged from inside the fuel tank.
Therefore, fill the fuel tank carefully
and slowly.

4108-1. Specifications
QGasoline quality
In very few cases, dr iveability problems may
be caused by the brand of gasoline you are
using. If driveability problems persist, try
changing the brand of gasoline. If this does
not correct the problem, consult your Lexus
dealer.
QRecommendation of the use of gasoline
containing detergent additives
OLexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.
OAll gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additives concentration
program.
OLexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gas-
oline and a list of marketers, please go to
the official website www.toptiergas.com.
QRecommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated
gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments. Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions.
QNon-recommendation of the use of
blended gasoline
OUse only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30 (30% ethanol [ ]), E50 (50%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
OIf you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
87.
OLexus does not recommend the use of
gasoline containing methanol.
QNon-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected.
The malfunction indicator lamp on the
instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
QIf your engine knocks
OConsult your Lexus dealer.
OYou may occasionally notice light knock-
ing for a short time while accelerating or
driving uphill. This is normal and there is
no need for concern.
Fuel information
You must only use unleaded gaso-
line.
Select octane rating 87 (Research
Octane Number 91) or higher. Use
of unleaded gasoline with an octane
rating lower than 87 may result in
engine knocking. Persistent knock-
ing can lead to engine damage.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.

Chafer This information has been prepared in
accordance with regulations issued by
the National Highway Traffic Safety
Administration of th
e U.S. Department
of Transportation.
It provides the purchasers and/or pro-
spective purchasers of Lexus vehicles
with information on uniform tire quality
grading.
Your Lexus dealer will help answer any
questions you may have as you read this
information.
QDOT quality grades
All passenger vehicle tires must con-
form to Federal Safety Requirements
in addition to these grades. Quality
grades can be found where applicable
on the tire sidewall between tread
shoulder and maximum section width.
For example: Treadwear 200 Traction AA
Temperature A
QTreadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course.
For example, a tire graded 150 would
wear one and a half (1 - 1/2) times as well
on the government course as a tire graded
100.
The relative performance of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
