Engine coolant refill procedure
*
[MC14000(FM)01/96]
After you have drained the engine cooling
system:
*
[MC14050(FM)01/96]
1. Fill the radiator with a 50/50 mixture of the
specified engine coolant concentrate and
water. Allow several minutes for trapped air
to escape (bubble out) and for engine coolant
to flow through the radiator.
*
[MC14100(FM)01/96]
2. Replace the radiator cap to its fully installed
position, then back off to the first stop. This
will prevent high pressure from building up
in the cooling system during this part of the
fill procedure.
*
[MC14150(FM)01/96]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[MC14200(FM)01/96]
4. Shut off the engine and allow the engine to
cool. Cover the radiator cap with a thick
cloth and cautiously remove it. Step back
while the pressure releases.
*
[MC14250(FM)01/96]
5. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[MC14300(FM)01/96]
6. If more engine coolant is necessary, fill the
overflow reservoir to the appropriate level
marked on the bottle.

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
again. If your vehicle is not on level ground,
you may need as much as five gallons (20 liters)
of fuel to start it.

Fuel Economy
*
[MC36500(FM)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(FM)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(FM)01/96]
To calculate fuel economy:
*
[MC36800(FM)01/96]
1. Fill the tank completely and record the
initial odometer reading.
*
[MC36900(FM)01/96]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
*
[MC37000(FM)01/96]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.
*
[MC37100(FM)01/96]
4. Use these equations to calculate your fuel
economy.
*

English: MPG = (total miles)/(gallons used).

How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
*
[MC39825(FM)04/96]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a not ready for I/M testing condition. To
prepare for I/M testing, the law specifies that
additional city and highway driving is necessary
to complete the check of the OBD II system.
[MC39830(FM)05/96]
The driving modes required to reach the ready
condition consist of a minimum of 30 minutes
city and highway driving as described below:
[MC39835(FM)05/96]
At least 20 minutes driving in stop and go, city
type traffic with at least four idle periods.
[MC39840(FM)05/96]
At least 10 minutes of driving on an expressway
or highway.
[MC39845(FM)05/96]
Before completing the above driving modes, the
engine must be warmed up and at operating
temperature. Once started, the vehicle must not
be turned off during these driving modes.
