DRIVING TIPS
474
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use “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.)
See “Checking the engine coolant level” on page 559 for
details of coolant type selection.
For the U.S.A. — “T oyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about −35C (− 31F).
For Canada — “Toyota Super Long Life Coolant” is a mixture
of 55% coolant and 45% deionized water. This coolant
provides protection down to about −42C (− 44F).
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 601 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 558 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.

IN CASE OF AN EMERGENCY
500B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning.
Check the following.

Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in the
acceptable range, turn off the engine and call your Lexus
dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible
by your Lexus dealer.
IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight
line. Move cautiously off the road to a safe place
— well away from the traffic. Avoid stopping on the
center divider of a highway. Park on a level spot with
firm ground.
2. Stop the engine and turn on your emergency
flashers.
3. F i r m l y s e t t h e p a r k i n g b r a k e a n d p u t t h e
transmission in “P”.
4. Have everyone get out of the vehicle on the side
away from traffic.
5. Read the following instructions thoroughly.

MAINTENANCE
529
You can be confident that your Lexus dealer’s service
department performs the best job to meet the maintenance
requirements of your vehicle.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. If
any problems should arise with your vehicle while under
warranty,
your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about doityourself maintenance?
Many of the maintenance items are easy to do yourself, if you
have a little mechanical ability and a few basic automotive
tools. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do −it− yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do−it−yourself maintenance can affect your warranty
coverage. See “Owner’s Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet” for the details.
GENERAL MAINTENANCE
Listed below are the general maintenance items that should be
performed at the intervals specified. It is recommended that
any problem you notice be brought to the attention of your
Lexus dealer or qualified service shop for their advice.
CAUTION
Make these checks only with adequate ventilation if you
run the engine.
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page 609 for
additional information.
Engine coolant level
Make sure the coolant level is between the “FULL” and “LOW”
lines on the see−through reservoir when the engine is cold.
See page 559 for additional information.
Radiator, condenser and hoses
Check that the front of the radiator and condenser are clean
and not blocked with leaves, dirt or insects. See page 561 for
additional information.

MAINTENANCE
532
Tire inflation pressure
Check the pressure with a gauge every two weeks,
or at least once a month and adjust as shown on the
tire and loading information label. See page 570 for
additional information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 585 for additional
information.
Tire rotation
Rotate the tires according to the maintenance
schedule. (For scheduled maintenance information,
please refer to the “Owner’s Manual Supplement /
Scheduled Maintenance”.) See “Rotating tires” on
page 584.DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
