Connect the jumper cables according to the following procedure:Connect a positive jumper cabl e clamp to the exclusive jump
starting terminal on your vehicle.
Connect the clamp on the other e nd of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the exclusive
jump starting terminal and any moving parts, as shown in the
illustration.
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that le vel for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the power
switch off.
Maintain the engine speed of t he second vehicle and start the
hybrid system of your vehicle by turning the power switch to ON
mode.
Make sure the “READY” indicato r comes on. If the indicator does
not come on, contact your Toyota dealer.4

●The needle of the engine coolant temperature gauge ( P. 103)
enters the red zone or a loss of hybrid system power is experi-
enced. (For example, the vehicle speed does not increase.)
● “Hybrid System Overh eat” is shown on the multi-information dis-
play.
● Steam comes out from under the hood.
■If the needle of the engine coolant temperature gauge enters
the red zone
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and radia-
tor core (radiator) for any
leaks.Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact
your Toyota dealer.
If your vehicle overheats
The following may indicate that your vehicle is overheating.

■Messages displays
The message illustrations used are intended as examples, and may differ
from the image that is actually displayed on the multi-information display.
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 compartment may be very hot.
● After the hybrid system has been turned off, check that the “READY” indi-
cator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally start, or the cooling fan may suddenly operate even if the gasoline
engine stops. Do not touch or approach rotating 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 radiator cap and the 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 system 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 system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additive.

*: The engine oil capacity is a reference quantity to be used when changingthe engine oil. Warm up the engine and turn off the hybrid system, wait
more than 5 minutes, and check the oil level on the dipstick.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil

Vehicle specifications
HIGHLANDER_HV_U (OM48F12U)
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
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 wi th 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.
How to read oil container label:
The International Lubricant Specification Advisory Committee
(ILSAC) Certification Mark is added to some oil containers to help
you select the oi l you should use.

■Gasoline quality
In very few cases, driveability problems may be caused by the brand of gaso-
line you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota 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 worldwide.
● The WWFC consists of four categories that are based on required emission
levels. In the U.S., category 4 has been adopted.
● The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
■ Recommendation of the use of gaso line containing detergent additives
● Toyota 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 concen-
tration program.
● Toyota 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.
Fuel information
You must only use unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher.
Use of unleaded gasoline with an octane rating lower than 87
may result in engine knocking. Persistent knocking can lead to
engine damage.
At minimum, the gasoline you use s hould meet the specifications of
ASTM D4814 in the U.S.A..
