Safety Connect LED light Indicators
When the “POWER” switch is turned to ON mode, the red indicator
light comes on for 2 seconds then turns off. Afterward, the green indi-
cator light comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage
conditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunc-
tion (contact your Toyota dealer)
●No indicator light (off) = Safety Connect service not active

■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision,
the system is designed to automatically call the response center.
The responding agent receives the vehicle’s location and attempts
to speak with the vehicle occupants to assess the level of emer-
gency. If the occupants are unable to communicate, the agent
automatically treats the call as an emergency, contacts the nearest
emergency services provider to describe the situation, and
requests that assistance be sent to the location.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (→P. 4 6 6 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

Maintenance and care
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To a v o i d d a m a g e t o t h e t i r e p r e s s u r e w a r n i n g v a l v e s a n d t r a n s m i t -
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. (→P. 4 7 7 )
■Driving on rough roads
Ta k e p a r t i c u l a r c a r e w h e n d r i v i n g on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions
may occur and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and
cause air leakage, which could result in an accident. If the caps are lost,
replace them as soon as possible.
