CHECKING THE ENGINE COOLANTLEVEL
1Reservoir cap2“F” (upper) line
3“L” (lower) line
Look at the seethrough coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the “F” and “L” lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see “Coolant
type selection” described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the “L” line,
add coolant. Bring the level up to the “F” line. If the coolant level drops within a short time after replenishing,
there
may be a leak in the system. Visually check the radiator,
hoses, engine coolant filler cap, radiator cap and drain cock
and water pump.
If you can find no leak, have your Lexus dealer test the radiator
cap pressure and check for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator
cap when the engine is hot.

Inspection and adjustment procedure
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. 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.
NOTICE
Use only the original valve cap. If any other
valve cap is used, it may corrode or melt and
become difficult or impossible to remove.
