Do not drive with objects left on top of the instrument
panel. They may interfere with the driver's field of
view. Or they may move during sharp vehicle
acceleration or turning, and impair the driver's
control of the vehicle. In an accident they may injure
the vehicle occupants.
NOTICE
Do not load the vehicle beyond the vehicle capacity
weight specified on the tire pressure label.

STARTING AND DRIVING
248
Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.ºABSº warning light

DRIVING TIPS

HOW TO SAVE FUEL AND MAKEYOUR VEHICLE LAST LONGER
Improving fuel economy is easy ± just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:

Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.

Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.

Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently. Remember,
however, that on cold winter days this may take a little
longer.

Accelerate slowly and smoothly. Avoid jackrabbit starts.

Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.

Avoid engine over±revving. Use a gear position suitable
for the road on which you are traveling.

Avoid continuous speeding up and slowing down.
Stop±and±go driving wastes fuel.

Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.

Avoid heavy traffic or traffic jams whenever possible.

Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.

Maintain a moderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.

Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle free from mud, etc.
This not only lessens weight but also helps prevent
corrosion.

IN CASE OF AN EMERGENCY

SL41002
10. Reinstall the wheel ornament.
Put the wheel ornament into position and then tap it firmly with
the side or heel of your hand to snap it into place.
CAUTION
Take due care in handling the ornament to avoid
unexpected personal injury.
11. After changing the wheel, check the air pressure of the
replaced tire. Stow all the tools, jack and flat tire securely.
If the pressure of the replaced tire is low, drive slowly to the
nearest service station and fill to the correct pressure.
Do not forget to reinstall the tire valve cap as dirt and moisture
could get into the valve core and possible cause air leakage.
If the cap is missing, put a new one on as soon as possible.
This is the same procedure for changing or rotating your tires.
CAUTION
 When reinstalling a standard tire, take due care in
handling the ornament to avoid unexpected personal
injury.
 Before driving, make sure all the tools, jack and flat
tire are securely in place in their storage location to
reduce the possibility of personal injury during a
collision or sudden braking.

MAINTENANCE
289
Where to go for service?
Lexus technicians are well±trained specialists and are kept up
to date with the latest service information through technical
bulletins, service tips, and in±dealership training programs.
They are well informed about the operation of all the systems
on your vehicle.
You can be confident that your Lexus dealer's service
department performs the best job to meet the maintenance
requirements of your vehicle.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. And
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 ºOwner's Guideº, ºOwner's Manual
Supplementº or ºWarranty 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 where adequate ventilation can
be obtained if you run the engine.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Tire pressure
Check the pressure with a gauge every two weeks, or at least
once a month and adjust as shown on the tire pressure label.
See page 323 for additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive wear.
See page 326 for additional information.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.

CHECKING TIRE PRESSURE
SV61004
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least once a month. And don't forget the spare! The pressure
for the spare tire should be the same with that for the standard
tire. Incorrect tire pressure can reduce tire life and make your
vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.
