HOW TO SAVE FUEL AND MAKE YOURVEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is easy ± just ta\
ke
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 traf fic,
it is better to turn off the engine and start again later.
Avoid engine overrevving. 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 traffic 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 needless 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.

ROTATING TIRES
63E005±1
To equalize tire wear and help extend tire life, Lexus recommends that
you rotate your tires approximately every 12000 km (7500 miles).
However, the most appropriate timing for tire rotation may vary
according to your driving habits and road surface conditions.
The wheel assemblies must be rotated as illustrated above.
When rotating tires, check for uneven wear and damage. Abnormal wear is\
usually caused by incorrect tire pressure, improper wheel alignment, out\
±of
balance wheels, or severe braking.
Before storing radial, snow or studded tires, mark the direction of rotation an\
d
be sure to install them in the same direction when using them again. Tire\
s
should be stored in a cool dry place.
CHECKING AND REPLACING TIRES
When to replace your tires

Replace the tires when the tread wear indicators show. The location of
the tread wear indicators is shown by the marks such as ºTWIº or º
Dº
marks molded on the sidewall of each tire.
The tires on your Lexus have built±in tread wear indicators to help you \
know
when the tires need replacement. When the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If you can see the indicators in two or
more adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears down below 4 mm
(0.16 in.).
