SECTION 3

IN CASE OF DRIVING EMERGENCY

CONNECTING A BATTERY

CHARGER

To connect a battery charger, first make sure

the engine is switched off. Disconnect the posi-

tive (+) lead from the battery. Never disconnect

the battery while the engine is running or alterna-

tor damage could result.

Connect the positive “+” (red) lead of the

charger to the positive “+” terminal on the bat-

tery. Next, connect the negative “-” (black) lead

of the charger to a suitable ground. Finally, plug

in or switch on the charger.

To disconnect the charger after charging, un-

plug the charger from the electrical outlets, re-

move the charger leads from the vehicle, and

reconnect the vehicle leads to the battery.

ENGINE OVERHEAT

If you see or hear steam escaping from the ra-

diator or the engine compartment or have any

other reason to suspect an extreme engine over-

heating condition, pull the vehicle over to the

roadside as soon as it is safe to do so, stop the en-

gine and get out of the vehicle.

An engine will overheat if the water pump

drive belt breaks, if the coolant is low or there is

a loss of coolant because of one or more of the

following:

− a leak in the cooling system

− a hose failure

− water pump failure

Also, be aware of the following situations,

which can cause temporary engine overheating:

− climbing a long hill on a hot day

− idling while stopped in traffic for long peri-

ods of time

− towing a trailer or automobile

− stopping after a period of high speed driving

If the TEMP indicator on the instrument panel

shows a rise in engine coolant temperature while

driving, take the following steps to try to lower

the overheating:

− If you are using the automotive air condition-

er, turn it off.

− If you are stopped in traffic, shift the trans-

mission into N (Neutral), and engage parking

brake.

If the temperature does not drop within a

minute or two:

− Pull the vehicle over to the roadside as soon

as it is safe to do so.

− Place the transmission in N (Neutral) and

press the accelerator to increase engine speed

(r.p.m.’s) to twice that of normal idle speed,

and hold it there for approximately two or

three minutes.

− If engine temperature does not go down, turn

the engine off and wait until the engine has

cooled before opening the engine compart-

ment

When no trace of escaping steam is heard or

seen, open the hood to check for the cause of the

overheat. Check hose connections and tighten if

necessary. Make sure there are no broken belts,

pulleys or hoses before adding any coolant to the

coolant reservoir.

For further information about overheating,

consult your Freightliner chassis operating guide.

WARNING

Do not attempt to push-start this vehi-

cle. Damage to the transmission or

other parts of the vehicle could occur.

WARNING

Operating a vehicle under a severe

overheating condition can result in

damage to the vehicle and may result

in personal injury.
