Problem
Possible causes/consequences and
M
MSolutions Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. A
display message may
also appear in the mul-
tifunction display 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 417). 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
mountainous terrain and stop-start traffic. DYNAMIC SELECT switch
This section describes the DYNAMIC SELECT
switch for all vehicles, except PLUG-IN
HYBRID vehicles. Information on the
DYNAMIC SELECT switch on PLUG ‑IN
HYBRID vehicles (Y page 295).
Use the DYNAMIC SELECT switch to change
the drive program. Depending on the drive
program selected, the following vehicle char- acteristics will change:
R the drive (engine and transmission man-
agement)
R the suspension
R the steering R
the availability of the ECO start/stop func-
tion
R the climate control
- the climate control settings
- the rear window heating operation period
- the performance of the seat heating
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 fourhours, drive program Cis activated when the
engine is next started. DYNAMIC SELECT switch

brightness will depend upon the brightness
of the ambient light.
i The light sensor in the instrument cluster
automatically controls the brightness of
the multifunction display.
In daylight, the displays in the instrument
cluster are illuminated. A dimming function
is not possible in daylight. Speedometer with segments
The speedometer is divided into segments on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available.
R Cruise control activated (Y page 230):
The segments light up from the stored
speed to the type-tested maximum speed.
R Variable SPEEDTRONIC activated
(Y page 233):
The segments light up from the start of the
scale to the selected limit speed.
R DISTRONIC PLUS activated (Y page 236):
One or two segments in the set speed
range light up.
R DISTRONIC PLUS detects a vehicle in front
moving more slowly than the stored speed:
The segments between the speed of the
vehicle 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.
PLUG-IN HYBRID vehicles: when you select
the E-MODE operating mode, the display in
the instrument cluster switches from rev
counter to wattmeter (Y page 289). Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the measured air tempera-
ture and not the road surface temperature.
The outside temperature display is in the mul- tifunction display (Y page 315).
Changes in the outside temperature are dis-
played after a short delay. Coolant temperature gauge

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.
All vehicles except PLUG-IN HYBRID vehicles: the coolant temperature gauge is in the lower
section of the rev counter (Y page 34).
PLUG-IN HYBRID vehicles: the multifunction
display shows the coolant temperature in the
Coolant Coolant submenu (Y page 327).
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise
to the end of the scale.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. Displays and operation

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 traf-
fic conditions, and switch off the engine.
X Safeguard the vehicle against rolling away (Y page 219).
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
otherwise be damaged.
X Pay attention to the coolant temperature display.
If the temperature increases again:
X Consult a qualified specialist workshop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature may rise to 120 †. #
