PARTS AND TOOLS
Here is a list of parts and tools you will need to perform
do−it−yourself maintenance. Remember all Lexus parts are
designed in metric sizes, so your tools must be metric.
Checking the engine oil level
Parts (if level is low):
“Toyota Genuine Motor Oil” or equivalent
See page 513 for details about engine oil selection.
Tools:
 Rag or paper towel
 Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low):
“Toyota Super Long Life Coolant” or similar high quality
ethylene glycol based non −silicate, non− amine, non−nitrite,
and non −borate coolant with long −life hybrid organic acid
technology (Coolant with long −life hybrid organic acid
technology is a combination of low phosphates and organic
acids.)
“Toyota Super Long Life Coolant” is a mixture of 50% coolant
and 50% deionized water (for the U.S.A.) or 55% coolant
and 45% deionized water (for Canada). This coolant
provides protection down to about −35C (− 31F).
Tools:
 Funnel (only for adding coolant)

Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to
serious engine trouble due to insufficient oil.
For detailed information on oil level check, see “Checking the
engine oil level” described below.
USED ENGINE OIL
CAUTION
 Used engine oil contains potentially harmful
contaminants which may cause skin disorders such
as inflammation or skin cancer, so care should be
taken to avoid prolonged and repeated contact with
it. To remove used engine oil from your skin, wash
thoroughly with soap and water.
 Dispose of used oil and used oil filters only in a safe
and acceptable manner. Do not dispose of used oil
and used oil filters in household trash, in sewers or
onto the ground. Call your Lexus dealer or a service
station for information concerning recycling or
disposal.
 Do not leave used oil within the reach of children.

CHECKING THE ENGINE OIL LEVEL
With the engine at operating temperature and turned off,
check the oil level on the dipstick.
1. To get a correct reading, the vehicle should be on level
ground. After turning off the engine, wait a few minutes for the
oil to drain back into the bottom of the engine.
2. Pull the dipstick out, hold a rag under the end and wipe it
clean.
3. Reinsert the dipstick and push it in as far as it will go, or the
reading will not be correct.
1Add oil2O.K.3Too full
4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the low level mark (
4) and
the full level mark (5), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.

ENGINE
512
If the oil level is below or only slightly above the low line,
add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low line and full line on the dipstick is
indicated as follows:1.5 L (1.6 qt., 1.3 Imp. qt.)
For the engine oil capacity, see “Specifications” on page 518.
When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.
NOTICE
 Be careful not to spill engine oil on the vehicle
components.
 Avoid overfilling, or the engine could be damaged.
 Check the oil level on the dipstick once again after
adding the oil.

ELECTRICAL COMPONENTS

If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a pain or burn, get medical
attention immediately.
 If electrolyte gets on your clothes, there is a
possibility of its soaking through to your skin, so
immediately take off the exposed clothing and follow
the procedure above, if necessary.
 If you accidentally to swallow electrolyte, drink a
large quantity of water or milk. Follow with milk of
magnesia, beaten raw egg or vegetable oil. Then go
immediately for emergency help.Checking battery exterior
1Terminals2Holddown clamp
Check the battery for corroded or loose connections,
cracks, or loose holddown clamps.
1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to
prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts — but
do not overtighten.
3. Tighten the hold −down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.
