2005 Lexus IS300 recommended oil

DRIVING TIPS
271
Make sure the engine oil viscosity is suitable for the cold
weather.
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 ªPº (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.

Add only ªT oyota Super Long Life Coolantº or similar
high quality ethylene glycol based non±silicate, non± amine, non±nitrite, and non±borate coolant withlong±life hybrid organic acid technology to fill theradiator. ªToyota Super Long Life Coolantº is a mix-ture of 50% coolant and 50% deionized water (for the
U.S.A.) or 55% coolant and 45% deionized water (forCanada).

If you spill some of the coolant, be sure to wash it offwith water to prevent it from damaging the parts orpaint.

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.
