2022 TOYOTA SIENNA HYBRID fuel cap release

821-4. Hybrid system
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “NAVIGA-
TION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the “Refer-
ence operation range” ( ) of
the ECO Accelerator Guid-
ance ( P.108) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.
 The engine braking force will be increased according to the
driving conditions to more effi-
ciently charge the hybrid bat-
tery (traction battery) after the
accelerator pedal is released.
■Predictive SOC* control
The following types of control
are performed based on data
such as road and traffic informa-
tion during route guidance by
the navigation system to help
ensure that the vehicle effi-
ciently uses electricity.
 When there is a long downhill
slope along the route, the sys-
tem reduces the hybrid bat-
tery (traction battery) level
before reaching the slope to
help ensure charging capacity
for regenerative braking while
traveling downhill.
 When traffic congestion is
predicted along the route, the
system helps ensure a certain
battery level before reaching
congested roads to reduce
the frequency of starting the
engine to charge the hybrid
battery (traction battery) due
to low battery levels.

2624-4. Refueling
1Press the opener to open the
fuel filler door.
The fuel filler door will open within
about 10 seconds of the switch
being pressed. Before refueling is
possible, a message will be shown
on the multi-information display in
the instrument cluster to indicate
the progress of the fuel filler door
opener.

■If the fuel filler door cannot be
opened
 P.501
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
WARNING
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
●Finish refueling within 30 min-
utes. If more than 30 minutes
passes, the internal valve
closes. In this condition, fuel
may overflow during the refuel-
ing process. Press the fuel filler
door opener switch again.
●Make sure that the fuel filler
door lock is not pushed by the
fuel nozzle boot, etc. If the
switch is held, the internal valve
closes and fuel may overflow.
To prevent it, press the fuel filler
door opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehi-
cle, such as causing the emis-
sion control system to operate
abnormally or damaging fuel
system components or the vehi-
cle’s painted surface.
