ES350 300h_OM_OM33A01U_(U)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving ma neuvers which place excessive stress on
the emergency towing eyelet and the cable or chain. Always be cautious of the
surroundings and other vehicles while towing.
●Gasoline vehicles: If the engine is not running, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
Hybrid vehicles: If the hybrid system is off, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
■Installing towing eyelet to the vehicle
Make sure that towing eyel et is installed securely.
If not securely installed, towing eyelet may come loose during towing.
NOTICE
■To prevent causing serious damage to the transmission when towing using a
wheel-lift type truck
Never tow this vehicle from the rear with the front wheels on the ground.
■To prevent damage to the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequate ground clearance for towing at the
opposite end of the raised vehicle. Without adequate clearance, the vehicle could
be damaged while being towed.
■To prevent body damage when to wing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.

■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 Tire Detergent Gasoline. For more
information on Top Tire Detergent Gasoline and a list of marketers, please go to the
official website www.toptiregas.com
.
■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.
Lexus recommends the use of cleaner burn ing gasoline and appropriately blended
reformulated gasoline. These types of ga soline 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.
●Use only gasoline containing a maximum of
10% ethanol.
DO NOT use any flex-fuel or gasoline that
could contain more than 10% ethanol,
including from any pump labeled E15, E30,
E50, E85 (which are only some examples
of fuel containing mo re than 10% ethanol).DO NOT use gasoline con-
taining more than 10% ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)
