ProblemPossible causes/consequences andPPSolutions
The coolant tempera-ture display shows avalue above 248 ‡(120 †). The coolantwarning lamp may alsobe on and a warningtone may sound.
The coolant level is too low. The coolant is too hot and the engine isno longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 242). Observe the warning notesas you do so and add coolant if necessary.
If the coolant level is correct, the engine radiator fan may be faulty.The coolant is too hot and the engine is no longer being cooled suf-ficiently.
XAt coolant temperatures below 248 ‡ (120 †), drive to the near-est qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving inmountainous terrain and stop-and-go traffic.

The automatic transmissionchanges gear automatically. Allforward gears are available.
Driving tips
Changing gear
The automatic transmission shifts through theindividual gears automatically when it is intransmission position[. This automatic gearshifting behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.
XEase off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.
Drive programs

accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If
you do not know the stored speed, store the
desired speed again.
