A warning light turning on briefly during
operation does not indicate a problem.
The brake pad wear limit  indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or  scraping noise
while driving, have the brake pads
checked and replaced by  your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.The rear step bumper is for  rear end
protection and easier step up loading.
CAUTION
Do not allow more than one person
to get on the rear step bumper at
a time. It is designed for only one
person.
Never drive the vehicle with anyone
on the rear step bumper.

If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to a Toyota dealer.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator or con-
denser when the engine is hot.
NOTICE
To prevent damage to the radiator
and condenser, do not perform the
work by yourself.
To check the fluid level, simply look at
the see through 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. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refi lling, it
may indicate a serious mechanical prob-
lem. If the level  is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir  cap by
hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cap back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess  moisture can  cause a
dangerous loss of braking.
CAUTION
Take care when filling the r
eservoir
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.
NOTICE
If you spill the fluid, be sure to wash
it off with water to prevent it from
damaging the parts or paint.
