HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel
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.
Keep the automatic transmission overdrive
turned on when engine braking is not required.
Driving with the overdrive off will reduce the fuel
economy. (For details, see ªAutomatic transmissionº
on page 284.)
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.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks
or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, a tire may slip off
a wheel or cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance,
and tire or snow chain clearance to the body and
chassis.
ALUMINUM WHEEL PRECAUTIONS
When installing aluminum wheels, check that the
wheel nuts are tight after driving your vehicle the first
1600 km (1000 miles).
If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not to damage the
aluminum wheels.
Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.
