fuel consumption TOYOTA PRIUS C 2018 Owners Manual (in English)

801-2. Hybrid system
PRIUS c_U (OM52G95U)
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cooling
the hybrid battery (traction bat-
tery). When the air intake vent is
blocked, the battery operations
will be restricted and cause a
decline in fuel consumption.
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. 490)

NOTICE
■Hybrid battery (traction battery) air intake vent
● Do not place objects that will block the air intake vent. When the air intake
vent is blocked, the battery operations will be restricted and cause a
decline in fuel consumption.
● Clean the air intake vent regularly to prevent the hybrid battery (traction
battery) from overheating.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. For information regarding filter cleaning or
replacement, contact your Toyota dealer.
● If “MAINTENANCE REQUIRED FOR TRACTION BATTERY COOLING
PARTS SEE OWNER’S MANUAL” is shown on the multi-information dis-
play, the air intake vent and filter may be clogged. Refer to P. 406 for infor-
mation on how to clean the air intake vent.
