DRIVING TIPS
183 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.
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 passengercarrying 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.
NOTICE
When towing a trailer, be sure to consult your Lexus dealer for
further information on additional requirements.
Weight limits
Before towing, make sure the total trailer weight, gross vehicle
weight, gross axle weight and trailer tongue load are all within
the limits.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

IN CASE OF AN EMERGENCY
197 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 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. Firmly set the parking brake and put the transmission in ”P”.
4. Have everyone get out of the vehicle on the side away from
traffic.
5. Read the following instructions thoroughly.
NOTICE
For vehicles equipped with the height control switch, be sure to
turn the ignition switch off before jacking. If this is not done, the
vehicle height adjustment function will operate, which may
cause body damage.
CAUTION
When jacking, be sure to observe the following to reduce the
possibility of personal injury:
Follow jacking instructions.
Do not start or run the engine while your vehicle is
supported by the jack.

MAINTENANCE
216Parking brake
Check that the pedal has the proper travel and that, on a safe incline,
your vehicle is held securely with only the parking brake applied.
Automatic transmission ”Park” mechanism
On a safe incline, check that your vehicle is held securely with the
selector lever in ”P” 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 261 for
additional information.
Engine coolant level
Make sure the coolant level is between the Upper and Lower lines
on the seethrough reservoir when the engine is cold. See page 233
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 253
for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 239 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 230 for additional
information.
Power steering fluid level
Check the level on the dipstick. The level should be in the ”HOT”
or ”COLD” range depending on the fluid temperature. See page 240
for additional information.
Exhaust system
Look for cracks, holes and loose supports. If you notice any change
in the sound of the exhaust or smell exhaust fumes, have the cause
located and corrected immediately. (See engine exhaust cautions in
Section 31.)

INTRODUCTION
222Remember 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.

Check the fluid level on the dipstick. If necessary, add automatic
transmission fluid DEXRONII or III.
If 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
8 0C or 140F 175F). You may also check the level when the
fluid is cold (about room temperature, 10C 30C or 50F 85F)
if the engine has not been run for about five hours.

Add fluid
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 ”COLD” range on the dipstick.
Similarly, if it is hot, the fluid level should be in the ”HOT” 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.
