(f) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on Ð
even for one block. It may ruin the engine.

MAINTENANCE
347 Accelerator pedal
Check the pedal for smooth operation and uneven pedal effort
or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and freeplay. Check the brake booster function.
Brakes
At a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the pedal has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking brake
applied.
Automatic transmission Parkº mechanism
On a safe incline, check that your vehicle is held securely with

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, 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.
Tire inflation pressure
Check the tire inflation 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 389 for additional information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 402 for additional
information.

ground, it is the fuel system has been damaged and it is
in need of repair. In this case, do not restart the engine.
FACTS ABOUT ENGINE OIL
CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.
The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.
