Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer
for information concerning recycling
or disposal.
Take care when filling the brake
fluid reservoir because brake fluid
can harm your eyes and damage
painted surfaces. If fluid gets in
your eyes, flush your eyes with
clean water immediately. If you still
feel uncomfortable with your eyes,
go to the doctor.
When servicing the vehicle with the
smart entry and start system, be
sure to keep the smart key away
from the vehicle. If the key is left
in the vehicle, the hybrid system
may start by pressing the “POWER”
switch with the brake pedal de-
pressed.
NOTICE
Remember that batteries and igni-
tion cable carry high currents or
voltages. Be careful of accidentally
causing a short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite, and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Do not pry the outer electrode of
spark plug against the center elec-
trode.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
 If the brake fluid is spilled on the
vehicle, be sure to wash it off with
water to prevent it damage to parts
or paint.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.
 When closing the hood, check to
see that you have not forgotten any
tools, rags, etc.

Checking brake fluid
82p002b
To check the fluid level, simply look at
the seethrough reservoir. The level
should be between the “MAX” and
“MIN” lines on the reservoir.
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.
