Towing
rl
It the car needs to be towed, call a professional towingservice. Never tow the car behind another car with just
a rope or chain. lt is very dange.ous.
Emergency Towing
There are three popular methods of towing a car:
Flat-bed Equipmont-The operator loads the car on theback of a truck. This is the best way of transporting thecar.
Whsol Lift Equipment-The tow truck uses two oivot-ing arms that go under the tires (front or rear) and liftsthem otf the ground. The other two wheels remain onthe ground.
Sling-type Equipmont-The tow truck uses metal cableswith hooks on the ends. These hooks go around partsof the frame or suspension and the cables lift that endof the car off the ground. The car's suspension and bodvcan be seriously damaged if this method of towing is at-tempted.
It the car cannot be transponed by flat-bed, it should betowed with the tfont wheels oft the ground. lf due todamage. the car must be towed with the front wheelson the ground, do the tollowing:
Manual Transmission
a Release the parking brake,a Shift the transmission to Neutral.
Automatic Transmission
a Release the parking brake.a Start the engine.
a Shift to @ oosition, then to S position.
a Turn off the engine.
NOTICE: lmproper towing preparation will damage thetransmission. Follow the above procedure exactly. lf you
cannot shift the transmission or stan the engine (auto-
matic transmission), your car must be transDorted on aflat-bed.
a lt is best to tow the car no tarther than SO miles lgokm). and keep the speed below 3b mph (bE km/h).
NOTICE: Trying to litt or tow your car by the bumperswill cause serious damage. The bumpers are not designedto support the car's weight.

parked on level ground,
Make cenain that the oil level indicated on the dip-
stick is between the upper and lower marks.
lf the l€vel has dropped close to the lower mark, add
oil until it reaches the upper mark.
CAUTION: Inssrt lho dipstick carotully to avoid
bending it.

How to Read Flowcharts
A flowchrrt is dasigned to be us€d fiom start to final repair. lt's like a map showing you the shortest distanco. But be-
ware: if you go off tho "map" anywhere but a "stop" symbol, you can easily get lost

NOTE:
a Tha tarm ,,lntormittgnt Failure" is used in these chans. lt simply means a system may have had a failur6, but it chocks
out OK !t this time. lf th6 Msltunction Indicator Lamp (MlL) on ihe dash does not come on, check for poor connections
or loose wires at all connectors rolated to the cilcuit that you are troubleshooting (see illustration b6low).
a Most ot tho troublashooting flowchans have you reset the Engine Control Module (ECM) and try to duplicate the Disg-
nostic Troubls Cod6 (DTC). lf the problem is intermittent and you c8n't duplicat€ the cod6, do not continus through
the flowchart, To do so will only rosult in confusion and, possibly, a ne€dlessly replaced ECM
a ,,opon,'and ,,short,, are common electrical terms. An open is a break in a wir6 or at a conn€ction. A short is an
accidontal connaction ot a wir€ to ground or to another wire. In simple electronics, this usually means som€thing won't
work at all. In complex electronics (like ECM's), this can sometimes mean something wolks, but not the way it's sup-
poSad to,
a il th6 olectricsl readings are not as specified when using the test harness, check the test harness connoctions bsfore
