BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.
The brake assist system becomes opera-
tive after the vehicle has accelerated to
a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
For an explanation of this system’s warn-
ing light, see “Service reminder indicators
and warning buzzers” in Section 1 5.
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.When stowing luggage or cargo in the
vehicle, observe the following:
Put luggage or cargo in the luggage
compartment when at all possible. Be
sure all items are secured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal-
ance.
For better fuel economy, do not carry
unneeded weight.
CAUTION
To prevent luggage or packages
from sliding forward during braking,
do not stack anything in the lug-
gage compartment higher than the
seatbacks. Keep luggage or pack-
ages low, as close to the floor as
possible.
Never allow anyone to ride in the
luggage compartment. It is not de-
signed for passengers. They should
ride in their seats with their seat
belts properly fastened. Otherwise,
they are much more likely to suffer
serious bodily injury, in the event
of sudden braking or a collision.

If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to Toyota dealer.
CAUTION
To prevent yourself from burning, be
careful not to touch the radiator or
condenser 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 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 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 some of the fluid, be sure
to wash it off with water to prevent
it from damaging the parts or paint.
