2006 LEXUS LX470 tire pressure

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.

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.
CHECKING TIRE INFLATION PRESSURE
63x600b
 Type A

CHASSIS
425
 Type B
The recommended cold tire inflation pressures, tire
size and the combined weight of occupants and
cargo (vehicle capacity weight) are described on the
tire and loading information label.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget the
spare! The pressure for the spare tire should be 220 kPa
(2.2 kgf/cm
2 or bar, 32 psi).
The following instructions for checking tire inflation
pressure should be observed:
 The inflation pressure should be checked only
when the tires are cold. If your vehicle has been
parked for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an
accurate cold tire inflation pressure reading.
 Always use a tire pressure gauge. The appearance
of the tire can be misleading. Besides, tire inflation
pressures that are even just a few pounds off can
degrade ride and handling.
 Do not bleed or reduce tire inflation pressure after
driving.
It is normal for the tire inflation pressure to
be higher after driving.
 Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located so
that the vehicle is balanced.

Inspection and adjustment procedure
63X601a
 1Tire valve
2Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of applying too much air, press the center
of the valve and release the air to adjust.
5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to the
valve and check for leakage. 6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire valve caps. W
ithout the
valve caps, dirt or moisture could get into the
valve core and cause air leakage. If the caps have
been lost, have new ones put on as soon as
possible.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire needs frequent refilling, have it checked by your
Lexus dealer.

CHASSIS

CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation):
Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowou ts from an overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire separation
 A greater possibility of tire damage from road
hazards
High tire pressure (overinflation):
 Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire damage from road
hazards
