pg. 48 Points to remember
Driving economy
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and
adjusting the speed of your vehicle to immediate traffic conditions. Observe the following rules:
●
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on
the accelerator pedal for the first few minutes of operation. A cold engine uses more fuel and is subject
to increased wear.
●
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to
reach normal operating temperature.
●
Drive carefully and avoid rapid acceleration and hard braking.
●
Do not exceed speed limit.
●
Avoid carrying unnecessary items (extra load) in car.
●
Check tire pressure regularly (check when tires are cold)
●
Remove snow tires when threat of snow or ice has ended.
●
Note that roof racks, ski racks, etc., increase air resistance and thereby fuel consumption.
●
Avoid using automatic kick-down feature unless necessary.
The following "Special Tips" apply to cars with automatic transmission
●
For steep hills and when driving for prolonged periods at low speed position 1 should be selected.
Avoid, however, repeated changes since this can cause overheating of the transmission oil. For driving
on mountain roads with long persistent uphill gradients, select position 2.
●
When negotiating long, steep downhill slopes, position 1 or 2 should be selected, in order to obtain
the best possible engine braking effect.
●
Do not hold the car stationary on an incline by using the accelerator pedal; instead, engage the parking
brake. This prevents unnecessary heating of the transmission oil.
●
When towing disengage the 4th gear (the indicator light on the instrument panel goes on).
Cooling system
The risk for overheating is greatest, especially in hot weather, when:
●
Towing a trailer up steep inclines for prolonged periods at full throttle and low engine rpm.
●
Idling for prolonged periods while the air conditioning is in operation.
