2018 TOYOTA RAV4 HYBRID fuel pump

801-2. Hybrid system
RAV4-HV_OM_OM42B81U_(U)
The cooling air intake and dis-
charge vents for the hybrid battery
(traction battery) are located
under the rear seats and between
the rear seats and deck board,
respectively. If the air intake vents
are blocked, it could lead to a
reduction in hybrid battery (trac-
tion battery) output.
The hybrid battery (traction battery)
output will not be reduced, even if
the space between the upper part
of the air discharge vents on the
back of the rear seat and deck
board is blocked with luggage, etc.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off sy stem activates, your vehicle will not restart.
To restart the hybrid system, contact your Toyota dealer.
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( →P. 560)

■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

■ Recommendation of the use of low emissions gasoline
Gasoline containing oxygenates such as ethers and ethanol, as well as refor-
mulated gasoline, are available in some cities. These fuels are typically
acceptable for use, providing they meet other fuel requirements.
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
