DRIVING TIPS
456
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use 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. (Coolant with long-life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
See Checking the engine coolant levelº on page 567 for
details of coolant type selection.
For the U.S.A. Ð Toyota Super Long Life Coolantº is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about -35C (-31F).
For Canada Ð Toyota Super Long Life Coolantº 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.

IN CASE OF AN EMERGENCY
487
B: 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
Ð 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 Pº.
4. Have everyone get out of the vehicle on the side
away from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following
to reduce the possibility of personal injury:
Turn off the active height control suspension
by pushing the active height control switch.
 Follow jacking instructions.

MAINTENANCE
535
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 do-it-yourself 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 your Owner's Guideº, Owner's Manual
Supplementº or Warranty Bookletº 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 622 for
additional information.
Engine coolant level
Make sure the coolant level is between the Fº and Lº lines on
the see-through reservoir when the engine is cold. See page
567 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 569 for
additional information.

MAINTENANCE
538
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.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.

CHECKING THE ENGINE COOLANT
LEVEL

1Reservoir cap2Fº (upper) line
3Lº (lower) line
Look at the see-through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the Fº and Lº lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see Coolant
type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the Lº line,
add coolant. Bring the level up to the Fº line.
