"Special Tips" 
●     
For steep hills and when driving for prolonged periods at low speeds, position L should be selected. 
Avoid, however, repeated changes since this can cause overheating of the transmission oil. For driving 
on long continuous uphill gradients, select position 3. 
●     
Select position L when descending long, steep downgrades and position 3 for less steep downgrades, 
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, apply the hand 
brake (parking brake). This prevents the transmission oil from becoming overheated. 
●     
When towing a trailer, select shift position 3. 
●     
The (E)conomy mode should be selected when the cruise control is engaged. 
Cooling system 
The risk for overheating is greatest, especially in hot weather, when: 
●     
towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm. 
●     
stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).  
To avoid overheating, the following rules should be followed: 
●     
Reduce speed and downshift when towing a trailer up long, steep inclines. The risk of overheating can 
be reduced by switching off the air conditioning system for a short time. 
●     
Do not let the engine idle unnecessarily for prolonged periods. 
●     
Do not mount auxiliary lamps in front of the grill.  
When the risk of overheating is imminent, or in the event of overheating, (the temperature gauge goes 
repeatedly into, or stays continually in, the red section) the following precautions should be taken: 
●     
Switch off the air conditioning system. 
●     
Stop the car and put the gear lever into neutral. Do not stop the engine! 
●     
If the vehicle is overheating, switch the heater to full (maximum) position. 
●     
Increase the engine speed to approx. 2000 rpm (twice idling speed). 
●     
Check the level of coolant in the expansion tank. Top-up, if necessary. See "Cooling System".  
The engine must NOT be running when coolant is topped-up.
