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 286). Observe the warning notes
as you do so and top up the 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 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. Manual transmission
Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all the way to the right. Otherwise, you could shift
unintentionally into 3rdor4th gear and dam-
age the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine to
overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients. There is otherwise a risk of damaging the clutch.
! On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer, you must shift into gear 1, 2or3in good time.
This uses the engine's braking effect. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. k

Forward gears Engaging reverse gear
! Only shift into reverse gear
Rwhen the vehi-

X Move the gear lever firmly to the left, beyond
the point of resistance, then forwards.
The ECO start/stop function is not available
when reverse gear is engaged. For further infor-
mation on the ECO start/stop function; see

Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop.
For an overview; see the instrument cluster illus-
tration (Y page 30). Displays and operation
Speedometer with segments
The segments in the speedometer indicate
which speed range is available. R Cruise control activated (Y page 156):
The segments light up from the stored speed to the type-tested maximum speed.
R Variable SPEEDTRONIC activated
(Y page 158): The segments light up from the start of the
scale to the selected limit speed.
R DISTRONIC PLUS activated (Y page 161):
One or two segments in the set speed range
light up.
R DISTRONIC PLUS detects a vehicle in front:
The segments between the speed of the vehi-
cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature.
The outside temperature display is in the multi-
function display (Y page 208).
The multifunction display shows changes in the
outside temperature with a delay. Coolant temperature gauge
G
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 left-hand side (Y page 30).206
Displays and operationOn-board computer and displays

Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 120 †.
At high outside temperatures and when driving
uphill, the coolant temperature may rise to the
end of the scale. Operating the on-board computer

X Top up the coolant, observing the warning notes before doing so
(Y page 286).
X If the coolant needs topping up more often than usual, have the
engine coolant system checked at a qualified specialist workshop. ? The fan motor is faulty.
X If the coolant temperature is below 120 †, you can continue driving

G WARNING
Never drive with an overheated engine. Driving when your engine is
overheated can cause some fluids which may have leaked into the
engine compartment to catch fire.
In addition, steam from an overheated engine can cause serious
burns, which can occur just by opening the bonnet.
There is a risk of injury.
X Stop the vehicle immediately, paying attention to road and traffic
conditions, and switch off the engine.
X Safeguard the vehicle against rolling away (Y page 150).
X Wait until the engine has cooled down.
X Make sure that the air supply to the engine radiator is not blocked,
e.g. by frozen slush.
X Do not start the engine again until the display message goes out and
the coolant temperature is below 120 †. The engine may otherwisebe damaged.
X Pay attention to the coolant temperature display.
X If the temperature increases again, consult a qualified specialist
workshop immediately.
Under normal operating conditions and with the specified coolant
