Type A
Type BTo check the fluid level, simply look at
the see through reservoir. The level
should be between the MAXº and
MINº 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 refilling, 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 cover by hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct lev-
el 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
Take care when filling the reservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.!
If you spill the fluid, be sure to wash
it off with water to prevent it from
damaging the parts or paint.

WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion,
the wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may cause loss of handling control. WHEEL SELECTION
When replacing wheels, care should
be taken to ensure that the wheels are
replaced by ones with the same load
capacity, diameter, rim width, and off-set.
Correct
replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may ad-
versely affect handling, wheel and bear-
ing life, brake cooling, speedometer/
odometer calibration, stopping ability,
headlight aim, bumper height, vehicle
ground clearance, and tire or snow chain clearance to the body and chassis. Replacement
with used wheels is not rec-
ommended as they may have been sub-jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened
may have structural damage and there-
fore should not be used. Never use an in-
ner tube in a leaking wheel which is de-
signed for a tubeless tire.
After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only the Toyota wheel nuts and
wrench designed for your aluminumwheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically checkyour aluminum wheels for damage. If
damaged, replace immediately.
