STARTING AND DRIVING

Drumindisc type parking brake system
Your vehicle has a drumindisc type parking brake system.
This type of brake system needs beddingdown of the brake
shoes periodically or whenever the parking brake shoes
and/or drums are replaced.
Have your Lexus dealer perform the beddingdown.
Brake assist system (vehicles with vehicle
skid control system)
When you slam the brakes on, the brake assist system
judges as an emergency stop and provides more powerful
braking for a driver who cannot hold down the brake pedal
firmly.
When you slam the brakes on, more powerful 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 malfunction.
The brake assist system becomes operative 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 warning light, see “ABS
warning light” on page 53.
BRAKE PAD WEAR LIMITINDICATORS
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have
the brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.

CHECKING BRAKE FLUID
To check the fluid level, simply look at the seethrough
reservoir. The level should be between the “MAX” and
“MIN” lines on the tank.
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 problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE J1703
brake fluid to the brake reservoir.
Remove and replace the reservoir cap by hand. Add brake
fluid up to the “MAX” line.
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 efficiency.
CAUTION
Take care when filling the reservoir because brake fluid
can harm your hands or eyes and damage painted
surfaces. If fluid gets in your hands or eyes, flush them
with clean water immediately. If you still feel
uncomfortable with your hands or eyes, go to the
doctor.
NOTICE
If you spill some of the fluid, be sure to wipe it off to
prevent it from damaging the parts or paintwork.
