OPERATION AND CARE OF NEW VEHICLE
It is important to observe the follow-
ing precautions as operation and care
of the vehicle, particularly during the
break–in period have a strong influ-
ence over the performance and ser-
vice life of the vehicle.
1. Start and let the engine idle until
it becomes thoroughly warmed up
and coolant temperature increases
beyond 50°C (or 125°F) before
starting off.
2. Avoid racing the engine, abrupt
starts and hard stops.
3. Avoid over loading the vehicle dur-
ing and after the break–in period.
Over loading
Over loading not only shortens the
service life of your vehicle but also
create serious potential safety haz-
ards.
The weight of payload must be limit-
ed within the GVW rating and distrib-
uted over the front and rear axles so
as not to exceed the axle capacities.
Refer to “MAIN DATA AND SPECIFI-
CATION” for GVW and Axle capaci-
ty.
Maintenance
In order to maintain safe and depend-
able vehicle operation, inspection and
adjustment should be performed as
outlined in “INSPECTION AND MAIN-
TENANCE”.
Your DAEWOO dealer is willing to
perform regular maintenance opera-
tion on your vehicle.

same time with engine oil.
Maximum engine speed
During the initial milage(Break–in period : 2,000km),
confine engine speed to 70% of the maximum and
scan the tachometer as you drive to prevent engine
over–running.
After the break–in period, increase the engine speed
gradually to complete running–in of the vital parts.
