reduce speed and shift the transmission into a lower gear.
This will provide additional braking effort from the engine.
When shifting from a higher gear to a lower gear with
the vehicle in motion, the engine and vehicle speed must be
synchronized to permit lower gear engagement. This is
accomplished by "Double Clutching" as follows:
Depress the clutch pedal.
Place the transmission control in neutral.
Engage the clutch and at the same time increase the
Depress the clutch pedal.
Shift the transmission to the desired lower range.
Synchronize the engine speed with the vehicle speed
as the clutch is engaged.
After entering the downhill grade, reduce the vehicle
speed with the brakes from time to time as required, to
prevent engine speeds exceeding maximum engine rpm.
Use hard "on-off" brake application to "snubdown" the
vehicle to keep it well under control.
With the vehicle driving the engine it is possible for the
engine speed to reach far in excess of the maximum
recommended rpm, causing serious damage to the engine. In
other words, on a downhill grade the vehicle should never be
driving the engine any faster than the engine would normally
be operating in the same gear pulling the load.

For the first 400 Km (250 Miles) hold vehicle speed
below 72 Km (45 Miles) per hour. Operate at reduced speeds
until engine is throughly warmed up. Avoid abrupt starts,
stops and lugging of engine at any time.
After the vehicle has been driven 400 Km (250 Miles)
occasional acceleration up to the governed or maximum
recommended RPM is permissible and desirable.
Sustained high speed driving must be avoided until the
vehicle has been driven at least 1600 Km (1000 Miles).
Do Not operate beyond maximum RPM at any time.
ENGINE EMERGENCY STARTING
The procedures below must be performed
exactly as outlined, otherwise injury to the
face, eyes, body, limbs and respiratory
system could result from fire or acid due to
battery explosion. Property damage could
To prevent shorting of the system, remove metal rings
or watches and do not allow metal tools to contact
positive terminal of battery.
Place transmission in PARK or in NEUTRAL and set
parking brake, in both vehicles.
Shut off lights, heater, air conditioner and any other
electrical loads, in both vehicles.
Eye protection should be worn if available. If not
available, shield eyes when near either battery.
Vehicle bodies or bumpers must not be in contact.
Connect jumper cable between POSITIVE posts of the
CHARGED and DISCHARGED batteries.
Connect other cable to the NEGATIVE post of the
CHARGED battery and to a good GROUND contact in
the engine area; not to the NEGATIVE post of the
DISCHARGED battery. Ground contact should be at
least twenty inches away from DISCHARGED battery.
Reverse above procedure when removing the jumper
If the battery is a Delco maintenance free
type, do not attempt to jump start the vehicle,
charge or test the battery if the indicator in the
battery is bright or light yellow. Install a new
