2006 LEXUS LX470 brake fluid

MAINTENANCE
389
Accelerator pedal
Check
the pedal for smooth operation and uneven pedal ef fort
or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and free play. Check the brake booster function.
Brakes
In a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the lever has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking
brake applied.
Automatic transmission “Park” mechanism
Check the lock release button of the selector lever for proper
and smooth operation. On a safe incline, check that your
vehicle is held securely with the selector lever in “P” position
and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after
the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors and back door, operate smoothly and all
latches lock securely. Make sure the engine hood secondary
latch secures the hood when the primary latch is released.
Tire inflation pressure
Check the pressure with a gauge every two weeks, or at
least once a month and adjust as shown on the tire and
loading information label. See page 424 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 438 for additional information.

MAINTENANCE
390
Tire rotation
Rotate the tires according to the maintenance schedule.
(For scheduled maintenance information, please refer to
the “Owner’s Manual Supplement / Scheduled
Maintenance”.) See page 437 for additional information.DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
 Engine continually runs hot; oil pressure gauge stays low.

CHECKING BRAKE FLUID
63X001b
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 or when the fluid level in the accumulator is
high.
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.
Refilling brake fluid:
1. Turn the ignition switch off.
2. Depress the brake pedal more than 40 times.
3. Remove the reservoir cap by hand. Add brake fluid up to the
“MAX” line. If you do not follow the procedure above, the reservoir may
overflow.
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 brake fluid reservoir because
brake fluid can harm your hands or eyes. If fluid gets on
your hands or in your eyes, flush the affected area 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.

NOTICE
Only use the Suspension fluid AHC for the active height
control suspension. If you fill other fluids such as brake
fluid, power steering fluid, engine oil, etc., the active
height control suspension could be damaged.
