3. Connect the negative (-) cable to the negative (-)
terminal of the assisting battery.
4. Make the final connection of the negative (-)
cable to an exposed metal part of the stalled
vehicle’s engine, away from the battery and the
carburetor/fuel injection system.Do notuse fuel
lines, engine rocker covers or the intake manifold as
groundingpoints.
Do not connect the end of the second cable
to the negative (-) terminal of the battery to
be jumped. A spark may cause an explosion of the
gases that surround the battery.
5. Ensure that the cables are clear of fan blades,
belts, moving parts of both engines, or any fuel
delivery system parts.
Jump starting
1. Start the engine of the booster vehicle and run
the engine at moderately increased speed.

Calculating fuel economy
1. Fill the fuel tank completely and record the initial
odometer reading (in kilometers or miles).
2. Each time you fill the tank, record the amount of
fuel added (in liters or gallons).
3. After at least three to five tank fill-ups, fill the
fuel tank and record the current odometer reading.
4. Subtract your initial odometer reading from the
current odometer reading.
5. Follow one of the simple calculations in order to
determine fuel economy:
Calculation 1:Multiply liters used by 100, then
divide by total kilometers traveled.
Calculation 2:Divide total miles traveled by
total gallons used.
Keep a record for at least one month and record the
type of driving (city or highway). This will provide
an accurate estimate of the vehicle’s fuel economy
under current driving conditions. Additionally,
keeping records during summer and winter will show
how temperature impacts fuel economy. In general,
lower temperatures give lower fuel economy.
Driving style—good driving and fuel economy
habits
Give consideration to the lists that follow and you
may be able to change a number of variables and
improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10%
savings in fuel.
•Steady speeds without stopping will usually give
the best fuel economy.
•Idling for long periods of time (greater than one
minute) may waste fuel.
•Anticipate stopping; slowing down may eliminate
the need to stop.
