Turn the power switch off and 
ensure that all the doors and win-
dows are closed.
 Confirm the type of fuel.
■Fuel types
 P.401
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded 
fuel pumps.
Opening the fuel tank cap
The fuel tank of your vehicle has a 
special structure, which requires a 
reduction in fuel tank pressure 
before refueling. After the opener 
switch has been pressed, it will take 
several seconds until the vehicle is 
ready for refueling.
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while 
refueling the vehicle. Failure to do so may 
result in death or serious injury.
●After exiting the vehicle and before 
opening the fuel door, touch an 
unpainted metal surface to discharge 
any static electricity. It is important to 
discharge static electricity before refu-
eling because sparks resulting from 
static electricity can cause fuel vapors 
to ignite while refueling.
●Always hold the grips on the fuel tank 
cap and turn it slowly to remove it. 
A whooshing sound may be heard 
when the fuel tank cap is loosened. 
Wait until the sound cannot be heard 
before fully removing the cap. In hot 
weather, pressurized fuel may spray 
out the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their 
body to come close to an open fuel 
tank.
●Do not inhale vaporized fuel. 
Fuel contains substances that are 
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle. 
Doing so may cause the fuel to ignite 
and cause a fire.
●Do not return to the vehicle or touch 
any person or object that is statically 
charged. 
This may cause static electricity to 
build up, resulting in a possible ignition 
hazard.
■When refueling
Observe the following precautions to 
prevent fuel overflowing from the fuel 
tank:
●Securely insert the fuel nozzle into the 
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
●Finish refueling within 30 minutes. If 
more than 30 minutes passes, the 
internal valve closes.  In this condition, 
fuel may overflow during the refueling 
process.
Press the fuel filler door opener switch 
again.

When trouble arises
One of the following may be the cause 
of the problem:
The electronic key may not be func-
tioning properly. ( P.383)
 There may not be sufficient fuel in 
the vehicle’s tank.
Refuel the vehicle. ( P.161)
 There may be a malfunction in the 
immobilizer system. ( P.60)
 There may be a malfunction in the 
steering lock system.
 The hybrid system may be malfunc-
tioning due to an electrical problem 
such as electronic key battery 
depletion or a blown fuse. However, 
depending on the type of malfunc-
tion, an interim measure is available 
to start the hybrid system.
One of the following may be the cause 
WARNING
■Speed limit when using the compact 
spare tire
Do not drive at speeds in excess of 50 
mph (80 km/h) when a compact spare 
tire is installed on the vehicle.
The compact spare tire is not designed 
for driving at high speeds. Failure to 
observe this precaution may lead to an 
accident causing deat h or serious injury.
■After using the tools and jack
Before driving, make  sure all the tools 
and jack are securely in place in their 
storage location to reduce the possibility 
of personal injury during a collision or 
sudden braking.
NOTICE
■Be careful when driving over bumps 
with the compact spare tire installed 
on the vehicle
The vehicle becomes lower when driving 
with the compact spare tire compared to 
when driving with standard tires. Be 
careful when driving over uneven road 
surfaces.
■Driving with tire chains and the com-
pact spare tire
Do not fit tire chains to the compact 
spare tire.
Tire chains may damage the vehicle body 
and adversely affect driving perfor-
mance.
■When replacing the tires
When removing or fitting the wheels, 
tires or the tire pressure warning valve 
and transmitter, contact your Lexus 
dealer as the tire pr essure warning valve 
and transmitter may be damaged if not 
handled correctly.
If the hybrid system will not

tart
Reasons for the hybrid system not 
starting vary depending on the situ-
ation. Check the following and per-
form the appropriate procedure:
The hybrid system will not start 
even though the correct starting 
procedure is being followed.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in 
your Lexus vehicle. Use Lexus 
approved “Toyota Genuine Motor Oil” 
or equivalent to satisfy the following 
grade and viscosity.
Oil grade: API SN/RC multigrade 
engine oil
Recommended viscosity: SAE 0W-16 SAE 0W-16 is the best choice for good 
fuel economy and good
 starting in cold 
weather.
If SAE 0W-16 is not available, SAE 
0W-20 oil may be used. However, it 
must be replaced with SAE 0W-16 at 
the next oil change.

4028-1. Specifications
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.
■If your engine knocks
●Consult your Lexus dealer.
●You 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.
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 can cause damage to 
your vehicle’s three-way catalytic con-
verters causing the emission control 
system to malfunction.
●Do not use gasohol other than the type 
previously stated. 
Other gasohol may cause fuel system 
damage or vehicle performance prob-
lems.
●Using unleaded gasoline with an 
octane number or rating lower than 
the level previously  stated may cause 
persistent he avy knocking. 
At worst, this may lead to engine dam-
age and will void the vehicle warranty.
■Fuel-related poor driveability
If poor driveability (poor hot starting, 
vaporization, engine knocking, etc.) is 
encountered after using a different type 
of fuel, discontinue the use of that type of 
fuel.
■When refueling with gasohol
Take care not to spill  gasohol. It can dam-
age your vehicle’s paint.
