2022 TOYOTA HIGHLANDER HYBRID battery

781-4. Hybrid system
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 mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates, your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played 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.474)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
