5-2. Steps to take in an emergency
When trouble arises
RX350/270_EE
If the engine will not start
If the engine will not start even though correct starting procedures are
being followed (→P. 180), consider each of the following points.
■The engine will not start, even though the starter motor operates
normally.
One of the following may be the cause of the problem:
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●The engine may be flooded.
Try to restart the engine again following correct starting proce-
dures. (→P. 1 8 0 )
●There may be a malfunction in the engine immobilizer system.
(→P. 115)
■The starter motor turns over slowly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low vol-
ume.
One of the following may be the cause of the problem:
●The battery may be discharged. (→P. 5 9 4 )
●The battery terminal connections may be loose or corroded.
■The starter motor does not turn over.
The engine starting system may be malfunctioning due to an electri-
cal problem such as an open circuit or a blown fuse. However, an
interim measure is available to start the engine. (→P. 588)

RX350/270_EERecommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in cold
weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 at the next oil
change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 0W-20, 5W-20 or
5W-30 engine oil is recom-
mended.
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.

RX350/270_EEHow to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation
by American Petroleum Institute)
(API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-
Conserving” means that the oil has
fuel-saving and environmental pro-
tection capabilities.
ILSAC Certification Mark
The International Lubricant Speci-
fication Advisory Committee
(ILSAC) Certification Mark is dis-
played on the front of the container.

Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■If premium gasoline is not available
If this premium type cannot be obtained, you can use unleaded gasoline with a
Research Octane Number as low as 91.
The use of such gasoline may cause the engine to knock or drastically reduce out-
put to protect itself while driving with a heavy load. To avoid this, refill the tank with
premium unleaded gasoline as soon as possible.
■If your engine knocks
●Consult any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●You may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.
EU area:
Your vehicle must use only unleaded gasoline conforming to European
standard EN228.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
Except EU area:
Your vehicle must use only unleaded gasoline.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its effective-
ness and the emission control system to function improperly.
●Gasoline engine (EU area): Bioethanol fuel sold under names such as “E50” or
“E85” and fuel containing a large amount of ethanol should not be used. The use
of these fuels will damage the vehicle's fuel system. In case of any doubt, ask any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
●Gasoline engine (except EU area): Bioethanol fuel sold under names such as
“E50” or “E85” and fuel containing a large amount of ethanol should not be
used. Your vehicle can use gasoline mixed with 10% max ethanol. The use of fuel
with more than 10% ethanol content (E10) will damage the vehicle’s fuel system.
You must ensure that refueling is carried out only from a source where fuel speci-
fication and quality can be guaranteed. In case of any doubt, ask any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
