■Secondary Collision Brake operat- ing conditions (if equipped)
The system operates when the SRS air-
bag sensor detects a collision while the vehicle is in motion. However, the sys-tem does not operate when the compo-
nents are damaged.
■Secondary Collision Brake auto- matic cancellation (if equipped)
The system is automatically canceled in
any of the following situations.
●The vehicle speed drops to approxi-
mately 10 km/h (6 mph).

■If a message about AWD is shown on the multi-information display (AWD models)
Perform the following actions.
●“AWD System Overheated Switching
to 2WD Mode”
AWD system is overheated. Stop the
vehicle in a safe place with the hybrid
system operating.*
If the message disappears after a while,
there is no problem. If the message
remains, have the vehicle inspected by
any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer immediately.
●“AWD System Overheated 2WD
Mode Engaged”
AWD system has been temporarily
released and switched to front-wheel
drive due to overheating. Stop the vehi-
cle in a safe place with the hybrid sys-
tem operating.*
If the message disappears after a while,
AWD system will automatically recover.
If the message remains, have the vehi-
cle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or

play message has turned off.
WARNING
■The ABS does not operate effec-
tively when
●The limits of tire gripping perfor- mance have been exceeded (such
as excessively worn tires on a snow covered road).
●The vehicle hydroplanes while driv-ing at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of
normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance.
Always maintain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with pot-
holes or uneven surfaces

WARNING
■When working on the engine compartment
●Make sure that “IGNITION ON” on the multi-information display 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 flu-ids 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.
●Take care because brake fluid can harm your hands or eyes and dam-age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience
discomfort, consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.482)
■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 fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.

Type A: If any washer does not
work, the washer tank may be
empty. Add washer fluid.
Type B: If any washer does not
work or the warning message
appears on the multi-information
display, the washer tank may be
empty. Add washer fluid.
With level gauge
If the washer fluid level is at “LOW”,
add washer fluid.
■Using the gauge (if equipped)
The washer fluid level can be checked
by observing the position of the level on the liquid-covered holes in the gauge.
If the level falls below the second hole
from the bottom (the “LOW” position), refill the washer fluid.

WARNING
■When the hybrid system is hot
Do not touch the radiator or con-
denser as they may be hot and cause serious injuries, such as burns.
■When the electric cooling fan is operating
Do not touch the engine compart-
ment.
With the power switch in ON, the electric cooling fan may automatically

■Routine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
power switch is turned to ON. It may
also take a few minutes to display the
tire inflation pressure after inflation
pressure has been adjusted.
●Tire inflation pressure changes with temperature. The displayed values
may also be different from the values
measured using a tire pressure
gauge.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate
properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire
that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire
that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the radio
wave signals is installed.
• If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is
extremely higher than the specified
level.
• If wheels without tire pressure warning
valves and transmitters are used.
• If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
●Performance may be affected in the
following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device
If tire position information is not cor-
rectly displayed due to the radio wave
conditions, the display may be cor-
rected by driving and changing the
