MAINTENANCE
428Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 496 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 466 for
additional information.
Engine oil level
Check the level on the dipstick with the engine turned off and
the vehicle parked on a level spot.
See page 452 for additional
information.
Power steering fluid level
Check the level through the reservoir. The level should be in
the “HOT” or “COLD” range depending on the fluid
temperature. See page 467 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or smell
exhaust fumes, have the cause located and corrected
immediately. (See “Engine exhaust cautions” on page 297.)
Vehicle interior
Items listed below should be checked regularly, e.g. while
performing periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail lights, turn signal
lights, and other lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning
buzzers function properly.
Steering wheel
Check that it ha s the specified free play. Be alert for changes
in steering condition, such as hard steering, excessive free
play or strange noise.
Seats
Check that all front seat controls such as seat adjusters,
seatback recliner, etc. operate smoothly. Check that the head
restraints move up and down smoothly and that the locks hold
securely in any latched position.
Seat belts
Check that the seat belt system such as buckles, retractors
and anchors operate properly and smoothly. Make sure the
belt webbing is not cut, frayed, worn or damaged.

MAINTENANCE

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

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.
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, including trunk lid, operate smoothly and
all latches lock securely. Make sure the engine hood
secondary latch secures the hood when the primary latch is
released.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.
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
loading and information label. See page 468 for
additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 481 for additional information.

POSITIONING THE JACK
61L047
Front
61L048
Rear
When jacking up your vehicle with the jack, position the
jack correctly as shown in the illustrations.
CAUTION
When jacking, be sure to observe the following to re-
duce the possibility of personal injury:
 Follow jacking instructions.
 Do not put any part of your body under the vehicle
supported by the jack. Otherwise, personal injury
may occur.
 Do not start or run the engine while your vehicle is
supported by the jack.
 Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in “P”. Block
the wheels on the opposite side of the jack up point
if necessary.
 Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone; use vehicle support
stands.
 Do not raise the vehicle with someone in the vehicle
 When raising the vehicle, do not place any objects on
top of or underneath the jack.
 For vehicles equipped with the height control switch,
be sure to turn the ignition switch off before jacking.
If this is not done, the vehicle height adjustment func-
tion will operate, which may cause an accident.

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. Without 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.
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 blowouts 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

mean a layer of rubber −coated parallel cords.
Cords mean the strands forming the plies in the
tire.
5 Summer tire or all season tire: An all season
tire has “M+S” on the sidewall. The tire not
marked with “M+S” is a summer tire. For details,
see “Types of tires” on page 479.
6 Radial tires or biasply tires: A radial tire has
“RADIAL” on the sidewall. A tire not marked with
“RADIAL” is a bias −ply tire.
7 “TUBELESS” or “TUBE TYPE”: A tubeless tire
does not have a tube inside the tire and air is
directly filled in the tire. Tube type tire has a tube
inside the tire and the tube maintains the air
pressure.
8 Load limit at maximum cold tire inflation
pressure: For details, see “Checking and
replacing tires” on page 481.
9 Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For recommended cold tire inflation
pressure, see “Tires and wheels” on pages 463
