DRIVING TIPS
270
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use ºToyota Super Long Life Coolantº or similar high
quality ethylene glycol based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid
organic acid technology.
See ºChecking the engine coolant levelº on page 337 for
details of coolant type selection.
ºToyota Super Long Life Coolantº is pre-mixed with 50%
coolant and 50% deionized water. This coolant provides
protection down to about -35 C (-31F).
NOTICE
Do not use plain water alone.
Check 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 378 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.

DRIVING TIPS
271
See page 335 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 - 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.
Do not use your parking brake when there is a possibility
it could freeze.
When parking, put the transmission into ºPº (automatic) or into
first or reverse (manual) and block the front wheels. Do not use
the parking brake, or snow or water accumulated in and around
the parking brake mechanism may freeze the parking brake,
making it hard to release.
Keep ice and snow from accumulating under the fenders. Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of
the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.

NOTICE

Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally causing a short circuit.

Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.

Do not drive with the air cleaner removed, or excessive engine wear could result. Also backfiringcould cause a fire in the engine compartment.

Do not overfill automatic transmission fluid, or thetransmission could be damaged.

Be careful not to scratch the glass surface with thewiper frame.
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):

ºToyota Genuine Motor Oilº or equivalent
Oil grade: API grade SL ºEnergy-Conservingº or ILSAC
multigrade engine oil. For recommended oil viscosity, see page 335.
Tools:

Rag or paper towel

Funnel (only for adding oil)
CHECKING THE ENGINE COOLANT LEVEL
Parts (if level is low):

Toyota Super Long Life Coolantº or similar high quality
ethylene glycol based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life hybrid organic acid technology.
Toyota Super Long Life Coolantº is pre-mixed with 50% coolant and 50% deionized water.

ENGINE
332The 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 under driving conditions such as high
speeds 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. 1.0L per 1000 km (1.1 qts./600 miles,
0.9 Imp. qts./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 ºChecking the
engine oil levelº on page 333.

Avoid overfilling, or the engine could be damaged.Check the oil level on the dipstick once again afteradding the oil.
Engine oil selection
ºToyota Genuine Motor Oilº is filled in your Lexus vehicle. Use
Lexus approved ºToyota Genuine Motor Oilº or equivalent to
satisfy the following grade and viscosity.
Oil grade:
API grade SL ºEnergy-Conservingº or ILSAC multigrade
engine oil.
Recommended viscosity (SAE):
SOIL14
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 oil may be
used. However, it should be replaced with SAE 5W-30 at
the next oil change.

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. 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. To ensure excellent lubrication performance for your engine,
ºToyota Genuine Motor Oilº is available, which has been
specifically tested and approved for all Lexus engines.
Please contact your Lexus dealer for further details about
ºToyota Genuine Motor Oilº.
