WARNING!
Always open the garage doors fully before starting the engine inside a garage to ensure adequate
ventilation. The exhaust gases contain carbon monoxide, which is invisible and odorless but very
poisonous.
Engine warm-up - initial driving procedure
Experience shows that engines in vehicles driven short distances are subject to abnormally rapid wear
because the engine never reaches normal operating temperature. It is therefore beneficial to reach normal
operating temperature as soon as possible. This is best achieved by driving with a light foot on the
accelerator pedal for a few minutes after starting.
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 the 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 transmission kick-down feature unless necessary.
