Problem
Possible causes/consequences and
M
MSolutions The coolant temperature
display is showing more
than 120 †. The coolant warning lamp may also
be on and a warning tone
may sound. The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 335). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is no longer being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECT controller
Use the DYNAMIC SELECT controller to change the drive program. Depending on the drive pro-
gram selected, the following vehicle character-
istics will change:
R the drive (engine and transmission manage-
ment)
R the transmission
R the suspension
R the steering
R the availability of the ECO start/stop function
If the ignition is switched off for less than four
hours, the previously selected drive program is
activated when the engine is next started. If the
ignition is switched off for more than four hours,
the Comfort drive program is activated when
the engine is next started. X
All vehicles (except Mercedes-AMG vehi-
cles):
turn DYNAMIC SELECT controller :as many times as necessary until the desired
drive program is selected.
The selected drive program appears in the
multifunction display. After five seconds the
display goes out.
In addition, the current drive program settings
are displayed in the multimedia system dis-
play.

WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade.
The coolant temperature gauge is in the instru-
ment cluster on the right-hand side (Y page 35).
Under normal operating conditions and with the specified coolant level, the coolant temperature
may rise to 120 †.
At high outside temperatures and when driving
in mountainous terrain, the coolant temperature may rise to the end of the scale. Operating the on-board computer
