4. Pull the dipstick out and look at the oil level on the end. If it is between
the full line (
5 ) and the low line ( 4 ), it is O.K.
62E003±1
If the oil level is below or only slightly above the low line, add engin\
e 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. The approximate quantity of oil needed to fill between the low line
and the full line on the dipstick is indicated below for reference.
When the level reaches within the correct range, return the filler cap and t\
urn
the cap clockwise until you hear a click.
Oil quantity. L (qt., lmp. qt.) 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be damaged. Check the oil level on
the dipstick once again after adding the oil.

Engine oil selection
Use API SH, ºEnergy±Conserving IIº or SJ, ºEnergy±Conservingº
multigrade engine oil or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
62L005±1
Temperature range anticipated before next oil change
SAE 5W±30 is the best choice for your vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W±30 engine oil in extremely low temperatures, the
engine may become difficult to start, so SAE 5W±30 engine oil is
recommended.
Oil identification marks
62L006±1

API Service Symbol
ILSAC Certification Mark
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
 The API Service Symbol is located anywhere on the outside of the
container.
The top portion of the label shows the oil quality by API (American
Petroleum Institute) designation such as SJ. The center portion of the label
shows the SAE viscosity grade such as SAE 5W±30.
ºEnergy±Conservingº, shown in the lower portion, indicates that the oil
has fuel±saving capabilities.
 The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is displayed on the front of the container.

CHECKING THE ENGINE COOLANT LEVEL
62E004±3

1Reservoir cap 2Upper line 3Lower line
Park the vehicle at a level spot and look at the see±through coolant
reservoir when the engine is cool. The coolant level is satisfactory if it is
between the upper and lower lines on the tank. If the level is low, add
ethylene±glycol type coolant.
The coolant level in the reservoir will vary with engine coolant temperatur\
e.
However, if the level is on or below the lower line, add coolant to bring the
level up to the upper line.
Use only ethylene±glycol type coolant. For information on ethylene±g\
lycol
coolant, see also ºEngine coolant selectionº described below.
If the coolant level drops within a short time after replenishing, there\
may be
a leak in the system. Visually check the radiator, hoses, radiator cap, drain
cock and water pump. If you can find no leak, have your Lexus dealer test the 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.
Engine coolant selection
Your coolant must contain ethylene±glycol antifreeze. In addition to
preventing freezing and subsequent damage to the engine, this will also
prevent corrosion. Further supplemental inhibitors or additives are neither
needed nor recommended.
Read
the antifreeze container for information on freeze protection. Follow t\
he
manufacturer 's directions for how much to mix with water. The total capacity
of the cooling system is given on page 193. We recommend 50% solution be
used for your Lexus, or a sufficient quantity to provide protection to about
±35 C (±31F).
NOTICE
Do not use alcohol type antifreeze or plain water alone.

CHECKING POWER STEERING FLUID
63E002±1
Check the fluid level through the reservoir. If necessary, add automatic
transmission fluid DEXRONII or III.
If the vehicle has been driven around 80 km/h (50 mph) for 20 minutes (\
a little
more in frigid temperatures), the fluid is hot (60 C ± 80C or 140F ± 175F).
You may also check the level when the fluid is cold (about room temperatur\
e,
10 C ± 30C or 50F ± 85F) if the engine has not been run for about five
hours.

1 If hot O.K. 2If hot add 3If cold O.K.
4If cold add
Clean all dirt off the reservoir and look at the fluid level. If the fluid is cold,
the level should be in the ºCOLDº range. Similarly, if it is hot, the fluid level
should be in the ºHOTº range. If the level is at the low side of the appropria\
te
range, add automatic transmission fluid DEXRON
II or III to bring the level
within the range.
To remove the filler cap, turn it counterclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the filler cap, visually check the steering \
box
case, vane pump and hose connections for leaks or damage.
CAUTION
The reservoir may be hot so be careful not to burn yourself.

Checking battery exterior
64E007

1Terminals 2Hold±down clamp
Check the battery for corroded or loose connections, cracks, or loose
hold±down 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.
NOTICE
 Make sure the engine and all accessories are turned off before
performing maintenance.
 When checking the ba ttery, remove the ground cable first and reinstall
it last.
 Be careful not to cause a short circuit with tools.
 Take care no solution gets into the battery when washing it.
Checking battery fluid
There are 2 types of batteries: maintenance type and non±maintenance
type.
A non±maintenance battery has ºMAINTENANCE FREE BATTERYº on its
top. A maintenance type battery does not have such indication.
Maintenance type battery
Check the fluid condition by the fluid level lines on the side of the battery. Or
if the battery has a hydrometer on its top, you can also check the hydro\
meter.
Non±maintenance battery
Check the battery condition by the hydrometer on the top of the battery.
