After the hybrid system has cooled
down, inspect the hoses and radia-
tor core (radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks, immedi-
ately contact your Lexus dealer.
4
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
5
Add coolant if necessary.
Water can be used in an emergency if
power control unit coolant is unavailable.
6
After stopping the hybrid system
and waiting for 5 minutes or more,
start the hybrid system again and
check if “Hybrid system overheated
Output power reduced” is shown
on the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact your
Lexus dealer.
If the message is not displayed:
The hybrid system temperature has
dropped and the vehicle may be driven
normally.
However, if the message appears again fre-
quently, contact your Lexus dealer.

WARNING
■
When inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
●
If steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot.

7-2. Steps to take in an emergency
7
When trouble
ari
ses
1
Stop the hybrid system. Set the
parking brake and shift the shift
lever to P.
2
Remove the mud, snow or sand
from around the front wheels.
3
Place wood, stones or some other
material under the front wheels to
help provide traction.
4
Restart the hybrid system.
5
Shift the shift lever to D or R and
release the parking brake. Then,
while exercising caution, depress
the accelerator pedal.
■
When it is difficult to free the vehicle
Press the
switch to turn off TRAC.
WARNING
●
After the hybrid system has been
turned off, check that the “READY”
indicator are off.
When the hybrid system is operating,
the gasoline engine may automatically
start, or the cooling fan may suddenly
operate even if the gasoline engine
stops. Do not touch or approach rotat-
ing parts such as the fan, which may
lead to fingers or clothing (especially a
tie, a scarf or a muffler) getting caught,
resulting in serious injury.
●
Do not loosen the coolant inlet cap or
coolant reservoir caps while the hybrid
system and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
■
When adding engine/power control
unit coolant
Add coolant slowly after the hybrid sys-
tem has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too
quickly can cause damage to the hybrid
system.
■
To prevent damage to the cooling sys-
tem
Observe the following precautions:
●
Avoid contaminating the coolant with
foreign matter (such as sand or dust
etc.).
●
Do not use any coolant additive.
If the vehicle becomes stuck
Carry out the following proce-
dures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Recovering procedure

7-2. Steps to take in an emergency
WARNING
■
When attempting to free a stuck vehi-
cle
If you choose to push the vehicle back
and forth to free it, make sure the sur-
rounding area is clear to avoid striking
other vehicles, objects or people. The
vehicle may also lunge forward or lunge
back suddenly as it becomes free. Use
extreme caution.
■
When shifting the shift lever
Be careful not to shift the shift lever with
the accelerator pedal depressed.
This may lead to unexpected rapid accel-
eration of the vehicle that may cause an
accident resulting in death or serious
injury.
NOTICE
■
To avoid damaging the transmission
and other components
●
Avoid spinning the front wheels and
depressing the accelerator pedal
more than necessary.
●
If the vehicle remains stuck even after
these procedures are performed, the
vehicle may require towing to be freed.

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.

Oil viscosity (0W-16 is explained here
as an example):
• The 0W in 0W-16 indicates the

the oil is at high temperature. An oil
with a higher viscosity (one with a

■
Gasoline quality
In very few cases, driveability 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.
■
Gasoline quality standards
●
Automotive manufacturers in the U.S.A.,
Europe and Japan have developed a
specification for fuel quality called the
World-Wide Fuel Charter (WWFC),
which is expected to be applied world-
wide.
●
The WWFC improves air quality by low-
ering emissions in vehicle fleets, and
improves customer satisfaction through
better performance.
■
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 pro-
gram.
●
Lexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gaso-
line and a list of marketers, please go to
the official website www.toptiergas.com.
■
Recommendation 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.
■
Non-recommendation of the use of
blended gasoline
●
Use 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).
●
If you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
91.
●
Lexus does not recommend the use of
gasoline containing methanol.
■
Non-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Fuel information
You must only use unleaded gaso-
line.
Select premium unleaded gasoline
with an octane rating of 87
(Research Octane Number 91) or
higher required for optimum
engine performance and fuel econ-
omy. If the octane rating is less than
87, damage to the engine may
occur and may void the vehicle war-
ranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.
A
B
C
402
8-1. 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 heavy 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.
