precautions
If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this part.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do−it−yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part
6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do−
it−yourself maintenance, see
”Parts and
tools”.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:

Checking brake fluid
Checking power steering fluid
Remove and replace the reservoir cover
by hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cover 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

because brake fluid can harm your
eyes and damage painted surfaces. If
