DRIVING TIPS
261
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 ºPº 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.
TRAILER TOWING
Your vehicle is designed primarily as a passenger±carrying
vehicle. Towing a trailer will have an adverse effect on
handling, performance, braking, durability and driving
economy (fuel consumption, etc.). Your safety and
satisfaction depend on the proper use of correct equipment
and cautious driving habits. For your safety and the safety of
others, you must not overload your vehicle or trailer. Lexus
warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes. Ask your local
Lexus dealer for further details before towing.

INTRODUCTION
325

Right after driving, the engine compartment ± the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. ± will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.

Do not smoke, cause sparks or allow open flames
near fuel or the battery. Their fumes are fl ammable.

Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Al ways use automotive jack stands or
other solid supports.

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
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 backfiring could cause
a fire in the engine compartment.

Do not overfill automatic transmission fluid, or the
transmission could be damaged.

Be careful not to scratch the glass surface with the
wiper 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 346.
Tools:

ENGINE

Coolant type selection
Use of improper coolants may damage your engine cooling
system. Your coolant must contain ethylene±glycol type
coolant for a proper corrosion protection of your engine that
contains aluminum components. Use ºToyota Long Life
Coolantº or equivalent.
In addition to preventing freezing and subsequent damage to
the engine, this type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives are neither
needed nor recommended.
Read the coolant container for information on freeze
protection. Follow the manufacturer's directions for how
much to mix with plain water (preferably demineralized
water or distilled water). The total capacity of the cooling
system is given on page 331.
We recommend to use 50% solution for your Lexus, to
provide protection down to about ±35C (±31F). When it is
extremely cold, to provide protection down to about ±50 C
(±58 F), 60% solution is recommended. Do not use more
than 70% solution for better coolant performance.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
CHECKING THE ENGINE FAN FLUID (SC400 ONLY)
Park the vehicle at a level spot and look at the see±thr ough
reservoir. If necessary, add automatic transmission fluid
DEXRON
 II or III.

CHASSIS
361
CHECKING POWER STEERINGFLUID
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III.

CHASSIS
362If the vehicle has been driven around 80 km/h (50 mph) for
20 minutes (a little more in frigid temperatures), the fluid is
hot (60C ± 80C or 140F ± 175F). You may also check
the level when the fluid is cold (about room temperature,
10 C ± 30C or 50F ± 85 F) if the engine has not been run
for about five hours.
1. Clean all dirt off the reservoir.
2. Remove the filler cap by turning it counterclockwise and
wipe the dipstick clean.
3. Reinstall the filler cap.
4. Remove the filler cap again and look at the fluid level. If
the fluid is cold, the level should be in the ºCOLDº range on
the dipstick. Similarly, if it is hot, the fluid level should be in
the ºHOTº range. If the level is at the low side of either range,
add automatic transmission fluid DEXRON
II or III to bring
the level within the range. 5. After replacing the filler cap, visually check the steering
box case, vane pump and hose connections for leaks or
damage.
