DRIVING TIPS
468Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 608
tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 559 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer Ð they will be pleased to help. Check the electronic ignition system for loose
connections or obvious damage.
Keep the door locks from freezing.
Squirt
lock de±icer or glycerine into the locks to keep them from
freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer's directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may damage your vehicle's paint.

ENGINE
554The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.
More oil is consumed by high±speed driving and frequent
acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption:
Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 Imp. qt./600 miles)
When judging the amount of oil consumption, keep in
mind that the oil may have become diluted, making it
difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and
consumes a normal amount of oil, the dipstick may not show
any drop in the oil level at all, even after 1000 km (600 miles)
or more. This is because the oil is gradually becoming diluted
with fuel or moisture, making it appear that the oil level has not
changed.
The diluting ingredients evaporate out when the vehicle is then
driven at high speeds, as on an expressway, making it appear
that oil is excessively consumed after driving at high speeds.
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 ªChecking the
engine oil levelº described below.USED ENGINE OIL

Engine oil selection
ªToyota Genuine Motor Oilº is used in your Lexus vehicle. Use
Lexus approved ªToyota Genuine Motor Oilº or equivalent to
satisfy the following grade and viscosity.
Oil grade: API grade SL ªEnergy±Conservingº or ILSAC
multigrade engine oil.
Recommended viscosity: SAE 5W±30
62Z002
Outside temperature
SAE 5W±30 is the best choice, for good fuel economy and
good starting in cold weather.
If SAE 5W±30 oil is not available, SAE 10W±30 may be
used. However, it should be replaced with SAE 5W±30 at
the next oil change.
Oil identification marks

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 SL.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W±30. ªEnergy±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.
