•Avoid extensive idling.
•Do not drive with your foot resting on the brake pedal.
Essentials of good fuel economy
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles (1,600
km) of driving (engine break-in period). You will get a more accurate
measurement after 2,000–3,000 miles (3,000–5,000 km).
The advertised fuel capacity of the fuel tank(s) on your vehicle is equal
to the rated refill capacity of the fuel tank(s) as listed inFuel tanksin
this chapter. The advertised capacity is the amount of the Indicated
Capacity and the Empty Reserve combined. Indicated Capacity is the
difference in the amount of fuel in a full tank and a tank when the fuel
gauge indicates empty. Empty Reserve is the small amount of usable fuel
remaining in the fuel tank after the fuel gauge indicates empty.
The amount of Empty Reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Filling the tank
For consistent results:
•Use the same fill rate setting (low - medium - high) each time during
filling.
•Allow three automatic click-offs when filling.
•Always use fuel of a known quality, preferably a national brand.
•Have the vehicle loading and distribution the same every time.
•When refueling a vehicle equipped with dual fuel tanks, if the two
tanks are not filled equally, the fuel gauge reading may fluctuate
slightly until the fuel level between the two tanks balance out and
become equal.
Your results will be most accurate if your filling method is consistent.
Note:For vehicles equipped with dual fuel tanks, engine performance
may degrade if fuel is not added to both tanks when refueling.

Maintenance Operation Frequency - Observation
Check and adjust transmission
controls
(2)High effort to shift or noisy
transmission.
Check fuel pump pressure Insufficient full-throttle power or
backfiring.
Clean radiator cap seal. Clean and
inspect the cap surface on the
radiatorWhen the cap does not hold
pressure.
Check the battery terminals for
corrosionWhenever electrical power supply
has diminished.
Tighten the wheel mounting nuts
to the specified torque. Refer to
Servicing your wheels and tires
in theMaintenance and
SpecificationschapterRequired initially at 500 and 1000
miles (800 and 1600 km). Perform
again at 500 and 1000 mile (800
and 1600 km) intervals after each
tire removal/replacement.
Clean body/door drain holes At least twice annually.
Clean windshield wiper blades As required.
Replace windshield wiper blades If wiping the blades with a clean
cloth and mild detergent and
washing with a cleaner does not
restore a clean wipe.
Lubricate body lock cylinders Noisy or difficult to operate.
Check headlamp alignment Lamp beams in wrong position
when vehicle operating loaded.
Check windshield washer fluid
level; add fluid if requiredIf washes do not spray when
operated.
1- During maintenance and repair, protect the fuel tube and the hose
assemblies, the power steering lines, and the brake lines from the
external heat, the acids and the abrasion that could damage the lines.
2- Check for (free) linkage action and ensure that (return) spring
force is adequate to maintain pedal free play.
3- Adjust, repair or replace as required with the same or equivalent
parts.
