DRIVING TIPS
256

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 you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene±glycol type coolant for a
proper corrosion protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent. See ºChecking the
engine coolant levelº on page 313 for instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution
for your Lexus, to provide protection down to about ±50 C
(±58 F). Do not use more than 70% solution for better coolant
performance.
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 338 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 312 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.

MAINTENANCE
291
Parking brake
Check that the lever has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking
brake applied.
Automatic transmission ºParkº mechanism
On a safe incline, check that your vehicle is held securely with
the selector lever in ºPº position and all brakes released.
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 344 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower
lines on the see±through reservoir when the engine is cold.
See page 313 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not have
to add distilled water. For longer life of the battery, however,
see page 338 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 321 for
additional information. Engine oil level
Check the level on the dipstick with the engine turned off and
the vehicle parked on a level spot. See page 310 for additional
information.
Power steering fluid level
Check the level on the dipstick. The level should be in the
ºHOTº or ºCOLDº range depending on the fluid temperature.
See page 322 for additional information.
Exhaust system
If you notice any change in the sound of the exhaust or smell
exhaust fumes, have the cause located and corrected
immediately. (See ªEngine exhaust cautionsº on page 221 in
Section 3±1.)

MAINTENANCE
292
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.

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):

Use API grade SJ, ºEnergy±Conservingº multigrade engine
oil or ILSAC multigrade engine oil. For recommended oil
viscosity, see page 312.
Tools:

Rag or paper towel

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

ºToyota Long Life Coolantº or equivalent
See ºChecking the engine coolant levelº on page 313 for
instructions.

Demineralized or distilled water
Tools:

Funnel (only for adding coolant)
