STARTING AND DRIVING139
DMaintain a moderate speed on high-
ways.The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
DKeep 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.
DKeep the bottom of your vehicle free
from mud, etc.This not only lessens
weight but also helps prevent corro-
sion.
DKeep your vehicle tuned−up and in
top shape.A dirty air cleaner, carbure-
tor out of adjustment, improper valve
clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis195
Never use second−hand tires on your
To y o t a .
Using tires whose previous history is un-
known is a risk.
Toyota recommends all four tires, or at
least both front or rear tires be re-
placed at a time as a set.
See “If you have a flat tire” on page 149
in Section 4 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
With single rear tires
With double rear tires
To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
10000 km (6000 miles). However, the
most appropriate timing for tire rotation
may vary according to your driving hab-
its and road surface conditions.
See “If you have a flat tire” on page 149
in Section 4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out−of−balance
wheels, or severe braking.
