If your vehicle runs out of fuel, try to stop on
level ground away from traffic. Add at least two
gallons (8 liters) of fuel to start your vehicle

you may need as much as five gallons (20 liters)
of fuel to start it.

Fuel Economy
*
[MC36500( ALL)01/96]
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
*
[MC36600( ALL)01/96]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[MC36700( ALL)01/96]
To calculate fuel economy:
*
[MC36800( ALL)01/96]
1. Fill the tank completely and record the
initial odometer reading.
*
[MC36900( ALL)01/96]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
*
[MC37000( ALL)01/96]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.

deteriorate due to oxidation. This can
damage rubber and other polymers in
the fuel system and may also clog
small orifices.

actual or expected storage periods exceed 60
days. Follow the instructions on the label. The
