Engine Cooling
In the event of an engine over heat condition,
see the procedures in the "In Case of Emergency"
section of this manual .
Long Uphill Grades
When ascending long uphill grades, the possi-
bility of engine overheating can be reduced by
down-shifting the transmission to a lower range
gear and reducing speed to 45 mph (75 km/h)
or below.
Transmission
See the procedure for checking the transmis-
sion fluid level in the Service and Maintenance
edition of this manual .
Parking
Parking of vehicles with trailers on a grade is
not recommended . However, should this be nec-
essary, the following sequence should be used :
1 . Apply regular brakes.
2 . Have someone place wheel chocks under
trailer wheels .
3 . When wheel chocks are in place, release reg-
ular brakes until chocks absorb load.
4. Apply parking brake.
5 . Place transmission selector lever in 'PARK"
position .
Reverse above sequence when starting.
If the vehicle is parked on a grade and the
transmission selector lever is placed in "PARK"
before the trailer wheels are chocked and parking
brake is set, the weight of the vehicle and trailer
exert so much force on the parking
pawl
in the
transmission that it may be difficult to pull the
selector lever out of "PARK ."
OPERATION IN
FOREIGN COUNTRIES
Your vehicle's engine is designed to operate
on unleaded or leaded fuel of approximately 91
research octane number .
If you plan to operate your vehicle outside
the continental limits of the United States or
Canada, there is a possibility that the best fuels
available are so low in anti-knock quality that
excessive knocking and serious engine damage
may result from their use. To obtain informa-
tion on the quality of fuels available in the
countries in which you plan to travel write to
1 2
GMC Truck 8ti Coach Division, General Motors
Corporation, Pontiac, Michigan 48053 (or in
Canada write to General Motors of Canada
Limited, Owner Relations Department, Oshawa,
Ontario), giving
" The vehicle identification number
(from
plate attached to right side of dash panel or
from the registration slip or title) .
" The country or countries in which you plan
to travel.
It is recommended that you do not operate
your vehicle in any country not having fuels
meeting the requirements of your vehicle's en-
gine as these MAY CAUSE ENGINE DAM-
AGE for which GMC Truck Sv Coach is not
responsible under the terms of the New Vehicle
Warranty or Emission Control Systems War-
ranty.
TRIP TIPS
A small amount of preparation prior to a trip
will save a lot of time when traveling .
When loading heavy items into your Motor-
home try to store them as low and centrally as
possible. This will aid performance and handling
of the vehicle . Remember even though an item
may not weigh much individually the sum
weight of several of these articles may be sub-
stantial .
