DRIVING TIPS
D Avoid engine overrevving. Use a gear position suitable for the
road on which you are traveling.
D Avoid continuous speeding up and slowing down.
Stop–and–go driving wastes fuel.
D 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.
D Avoid heavy traffic or traffic jams whenever possible.
D Do not rest your foot on the brake pedal. This causes needless
wear, overheating and poor fuel economy.
D 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.
D 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.
D Keep the bottom of your vehicle free from mud, etc. This not
only lessens weight but also helps prevent corrosion.
200
D Keep your vehicle tuned–up and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine performance and
contribute 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. (For scheduled
maintenance information, please refer to the separate "Owner's
Manual Supplement/Maintenance Schedule".)
CAUTION
Never turn off the engine to coast down hills. Your power
steering and brake booster will not function without the
engine running. Also, the emission control system operates
properly only when the engine is running.
