7-2. Steps to take in an emergency
If your vehicle needs to be towed
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
●The hybrid system is operating but the vehicle will not move.
●The vehicle makes an abnormal sound.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency
towing eyelet. This should only be
attempted on hard surfaced roads
for short distances at under 18 mph
(30 km/h).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in good
condition.
If towing is necessary, we recommend having your vehicle towed by
your Lexus dealer or a commercial towing service, using a lift-type
truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.

■Recommendation of the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to avoid
the build-up of engine deposits.
●All 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.
●Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gasoline and a list of marketers, please go to the
official website www.toptiergas.com.
■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octane rating no lower than
87.
●Lexus does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline 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.
●Use only gasoline containing up to 15% eth-
anol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol,
including from any pump labeled E30, E50,
E85 (which are only some examples of fuel
containing more than 15% ethanol).DO NOT use gasoline con-
taining more than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

8-1. Specifications
This information has been prepared in accordance with regulations issued
by the National Highway Traffic Safety Administration of the U.S. Depart-
ment of Transportation.
It provides the purchasers and/or prospective purchasers of Lexus vehi-
cles with information on uniform tire quality grading.
Your Lexus dealer will help answer any questions you may have as you read this
information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety Require-
ments 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
■Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified govern-
ment 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 cli-
mate.
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and
they represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking (straight
ahead) traction tests and does not include cornering (turning) traction.
