[. . . ] To make driving more economical, keep the needle in this section as much as possible. With the needle in the white section the turbocharger is engaged. 4 Resetting the tripmeter Indicates the temperature of the coolant in the engine. If the pointer repeatedly enters the red sector, or if it remains there, you should immediately check the coolant level. Also check the coolant level if the warning light comes on; see 7:10. [. . . ] Remove your foot from the clutch pedal while driving. In order to obtain the best possible fuel economy, try to use 5th gear as often as possible i n highway driving at more than approx. In order to avoid unnecessary wear and tear on the gearbox, follow the gear pattern on the gear lever. For instance, do not change directly from second to fifth gear. The gear lever must first be moved to neutral (between 3rd and 4th gear) in order to engage reverse gear. The gear selector is blocked so that it cannot be removed directly from 5th gear into reverse. CAUTION! Reverse gear should not be engaged if the vehicle is moving forward. Automatic transmission R Reverse N Neutral The car must be at a complete standstill before position R is selected!The engine may be started in this position since no gear is engaged. Engage the parking brake whenever the car is at a standstill and the gear lever is in position N. L Low gear D Drive Gear selector positions P Parking Gear positions The normal driving position is indicated by D. When mode E or S is selected, the transmission makes use of all the gears automatically, changi ng up or down in response to acceleration and speed. The car should be at a complete standstill when position D is selected after R. The transmission does not change up in position L. Select position L if you wish to drive in first and second gear and you do not wish to change up, for example if you are driving in hilly terrair since position L offers the best engine braking power. In this position the indicator lamp in the i nstrument panel lights up The transmission will make a very noticeable shift down from 2nd to 1st gear if road speed drops to below 30 mph (50 km/h). 3 Low gear Select this position when you start the engine or park the car. **The kick-down facility is always available in these positions. Automatic transmission' Kick-down When you depress the accelerator pedal all the way to the floor, past the normal full acceleration point, the transmission automatically selects a lower gear to provide the kick-down facility. When you reach the maximum speed for the gear now selected or if you release the accelerator pedal somewhat from the kick-down position, the transmission will automatically select a higher gear once more. Kick-down can be used to obtain maximum acceleration, for example when overtaking. The transmission is equipped with a kickdown inhibitor which acts on all gears. Starting and stopping a car equipped with an automatic transmission 1 Move the selector lever to position P. 2 Start the engine with the ignition key. 3 Press the brake pedal and move the selector lever to the required position; the selected gear will be engaged after a slight delay. Engagement will be clearly felt - the car will start to pull somewhat. The engine must operate at idling speed!Never press the accelerator until you have felt the gear engage properly!If you accelerate too soon after selecting a gear, engagement will be jerky and the transmission will be subjected to unnecessary wear. 4 Release the brake pedal and accelerate. [. . . ] An oxygen sensor monitors the composition of the exhaust gases leaving the engine. The value provided by this analysis of the exhaust gases is fed into an electronic system which constantly regulates the injectors. The unit adjusts the airfuel ratio to provide optimum conditions for combustion and efficient reduction of the three major pollutants (hydrocarbons, carbon monoxide and nitrous gases) by means of a 3-way catalytic converter. Positive crankcase ventilation, fuel evaporation system Positive crankcase ventilation Crankcase ventilation prevents the emission of crankcase gas into the surrounding air. Instead, these gases are sucked via the inlet manifold down into the cylinders where they aid the combustion process. [. . . ]
