WA R N I N G
●Do not smoke, cause sparks or
expose an open flame to fuel or the
battery. Fuel and battery fumes are flammable.
●Be extremely cautious when work-ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●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 engine switch is OFF.
With the engine 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.426)
■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.

■Pre-driving check
Check that the hood is fully closed
and locked.
If the hood is not locked properly, it
may open while the vehicle is in motion and cause an accident, which
may result in death or serious injury.
■After installing the support rod
into the slot
Make sure the rod supports the hood securely preventing it from falling
down onto your head or body.
NOTICE
■When closing the hood
Be sure to return the support rod to its
clip before closing the hood. Closing
the hood with the support rod not clipped could cause the hood to bend.

■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene glycol based non-silicate, non-amine,
non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses,
engine coolant reservoir caps, drain
cock and water pump. If you cannot find a leak, have any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.

■When the engine is hot
Do not remove the engine coolant
reservoir cap.
The cooling system may be under
pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mix-
ture of water and antifreeze must be
used to provide proper lubrication, corrosion protection and cooling. Be
sure to read the antifreeze or coolant
label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or
paint.

●Vehicles with entry function: Unlock-ing the doors using the smart entry &
start system may not be possible
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical
key to lock/unlock the doors.
●Start the engine with the engine
switch in ACC. The engine may not
start with the engine switch turned off. However, the engine will operate nor-
mally from the second attempt.
●The engine switch mode is recorded
by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it
was in before the battery was discon-
nected. Make sure to turn off the engine before disconnecting the bat-
tery. Take extra care when connecting
the battery if the engine switch mode prior to discharge is unknown.
If the system will not start even after
multiple attempts, contact any author- ized Toyota retailer or Toyota authorized
