If a Mark Levinson brand audio system is installed:
G22066
Automatic sound levelizer (ASL):
When the audio sound becomes difficult to be heard due to
road noise, wind noise, etc. during driving, touch the “ASL”
switch. The system adjusts to the optimum volume and tone
quality according to the noise level.
When the system is on, the sound adjustment level is
displayed on the screen.
SURROUND:
If you touch “SURROUND”, surround sound will be enabled. (d) Your radio antenna
The wire antenna is mounted inside the rear window.
NOTICE

When cleaning the inside of the rear window, be
careful not to scratch or damage the wire antenna.
 Putting a window tint (especially, conductive or
metallic type) on the rear window may affect the
reception of radio or mobile telephone. For the
installation of the window tint, consult with your
Lexus dealer.
(e) Your cassette player
When you insert a cassette, the exposed tape should be to the
right.
NOTICE
Do not oil any part of the cassette player, and do not
insert anything except a cassette tape into the slot.

DRIVING TIPS
452
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 527 for
details of coolant type selection.
For the U.S.A.—“Toyota 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 pr ovide enough power for winter
starting. Page 571 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 525 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 ”P” 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.

4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the full level mark (
5 ) and
the low level mark ( 4 ), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.

If the oil level is below or only slightly above the low level
mark, add engine oil of the same type as already in the
engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low and full on the dipstick is indicated
as follows:
1.5 L (1.6 qt., 1.3 lmp. qt.)
For the engine oil capacity, see “Specifications” on pages 512
and 515.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.

The following label is affixed on the right side of the

the label when the differential oil is replaced.
Synthetic oil information labelNOTICE
Use of differential oil other than “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90” or its
equivalent may damage the dif ferential gear of your vehicle
and diminish fuel efficiency. For the reasons mentioned
above, Lexus recommends use of “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90”.
Another differential oil of matching quality can also be
used, (but note that despite the similarity in nomenclature
between “Toyota Genuine Differential Synthetic gear oil
API GL5 SAE 75W90” and oils that meet SAE 75W90
specifications, compliance with the SAE specification
does not guarantee that an oil has all characteristic
required to avoid the problem described above.) If you are
unable to locate an equivalent to “Toyota Genuine
Differential Synthetic gear oil API GL5 SAE 75W90”,
contact your Lexus dealer for further details or another
duly qualified and equipped professional.

*Change automatic transmission fluid only as necessary.
Generally, it is necessary to change automatic transmission
fluid only if your vehicle is driven under one of the Special
Operating Conditions listed in your “Owner’s Manual
Supplement / Scheduled Maintenance”. When changing the
automatic transmission fluid, use only “Toyota Genuine ATF
WS” (ATF JWS3324 or NWS9638) to aid in assuring optimum
transmission performance.NOTICE
Using automatic transmission fluid other than “Toyota
Genuine ATF WS” may cause deterioration in shift
quality, locking up of your transmission accompanied
by vibration, and ultimately damage the automatic
transmission of your vehicle.

3. Wipe off
the surface of the leather with a dry soft cloth. Allow
the leather to dry in a ventilated shaded area. Excess of wet
may cause the hardening or shrinking of the leather.
NOTICE
 Dirt or sand adhered to the leather may damage the
treated surface and cause it to wear earlier. Remove
dirt or sand using a vacuum cleaner.
 If a stain should fail to come out with a neutral
detergent, apply a cleaner that does not contain an
organic solvent.
 Never use organic substances such as benzine,
alcohol or gasoline, or alkaline or acid solutions for
cleaning the leather as these could cause
discoloring.
 Use of a nylon brush or synthetic fiber cloth, etc. may
scratch the fine grained surface of the leather.
 Mildew may develop on soiled leather upholstery. Be
especially careful to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight may cause the
leather surface to harden and shrink. Keep your
vehicle in a shaded area, especially in the summer.
 The interior of your vehicle is apt to heat up on hot
summer days, so avoid placing on the upholstery
items made of vinyl or plastic or containing wax as
these tend to stick to leather when warm.
Improper cleaning of the leather upholstery could
result in discoloration or staining.
Nonleather trim (Dash and sun visors)
The nonleather trim may be easily cleaned with a mild
soap or detergent and water.
First vacuum over the upholstery to remove loose dirt. Then,
using a sponge or soft cloth, apply the soap solution to the
non−leather trim. After allowing it to soak in for a few minutes
to loosen the dirt, remove the dirt and wipe off the soap with a
clean damp cloth. If all the dirt does not come off, repeat the
procedure. Commercial foaming −type cleaners are also
available which work well. Follow the manufacturer’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline or window cleaner
on the interior.
