as it is safe to do so.

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• For vehicles equipped with
, use 4H
or 4L position only when necessary.
4-Wheel Drive operation lowers fuel
economy.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in

tion” section of this manual.
