2021 TOYOTA SIENNA HYBRID warning light

561-1. For safe use
Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases contain harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in
the vehicle even when the back
door is closed, open the side
windows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time.
If such a situation cannot be
avoided, park the vehicle in an
open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.
■Exhaust pipe
The exhaust system needs to be
checked periodically. If there is a
hole or crack caused by corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

621-2. Child safety
ward.
 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.
WARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Never install a rear-facing child
restraint system on the front
passenger seat even if the “AIR
BAG OFF” indicator light is illu-
minated. In the event of an acci-
dent, the force of the rapid
inflation of the front passenger
airbag can cause death or seri-
ous injury to the child if the rear-
facing child restraint system is
installed on the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, raise the seat-
back as much as possible,
move the seat to the rearmost
position, even if the “AIR BAG
OFF” indicator light is illumi-
nated.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.

841-4. Hybrid system
■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.472)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 3.1 gal.
[11.9 L, 2.6 Imp. gal.], when the
vehicle is on a level surface. This
value may vary whe n the vehicle is
on a slope. Add ext ra fuel when the
vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
hybrid vehicles incorporate elec-
tromagnetic shielding, and there-
fore emit approximately the same
amount of electromagnetic waves
as conventional gasoline pow-
ered vehicles or home electronic
appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Hybrid battery (tr action battery)
The hybrid battery (traction battery)
has a limited service life. The lifes-
pan of the hybrid battery (traction
battery) can change in accordance
with driving style and driving condi-
tions.
WARNING
■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the warning labels
attached to the vehicle.
●Never try to open the service
plug access hole located under-
neath the console box. The ser-
vice plug is used only when the
vehicle is serviced and is sub-
ject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Pull your vehicle off the road,
shift the shift le ver to P, apply
the parking brake, and turn the
hybrid system off.
●Do not touch the high voltage
parts, cables and connectors.
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●If a fluid leak occurs, do not
touch the fluid as it may be
strong alkaline electrolyte from
the hybrid battery (traction bat-
tery). If it comes into contact
with your skin or eyes, wash it
off immediately with a large
amount of water or, if possible,
boric acid solution. Seek imme-
diate medical attention.

WARNING
■If a safety system warning
light does not come on
Should a safety system light such
as the ABS and SRS warning light
not come on when you start the
hybrid system, this could mean
that these system s are not avail-
able to help protect you in an acci-
dent, which could result in death
or serious injury. Have the vehicle
inspected by your Toyota dealer
immediately if this occurs.
