Because its trying to defy gravity.. lol
The fact that its going up hill, kind of explains it.
most daewoo lanos's will only cut out on an extremely steep hill and if you are goin up a steep hill u should use the power button that is located on the gearstick of an automatic if it is a manual im sorry but i can not help you.
You can save gas driving a steep hill by driving the car at a lower RPM.
I shifted gears to gain more power driving up the steep, mountain road.
Using a lower gear while driving on steep inclines provides better control over the vehicle, increases engine power, and reduces strain on the brakes. This can help prevent the vehicle from rolling back and improve overall safety while driving uphill.
Downshift a gear until you have sufficient power without overevving engine.
For driving on steep hills as well as slow-speed driving, in a parade for example.
When driving a car with an automatic transmission up a steep hill it is not necessary to shift gears. The car will do that on its own when necessary.
You should reverse down a steep incline (slope) when driving a forklift that has a load on the forks.
In an automatic transmission, "2" and "L" (Low) are used for specific driving conditions. You should use "2" when you want to limit the transmission to the lower gears for better acceleration and control, such as when driving up steep hills. "L" is used for maximum power and torque, often in situations like towing or driving in very steep terrain or slippery conditions, where you need to maintain a lower gear for more control.
Driving up a very steep hill?
gear down and use the motor to assist in braking
You should change down to a lower gear, 3rd gear or if the grade is very steep 2nd gear.
