Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 28). Hybrid vehicles
General notes
Hybrid technology combines a fuel-efficient
internal combustion engine with a powerful
electric motor. Important safety notes
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be
sure to observe the following sections:
R Transporting the vehicle (Y page 448)
R Towing the vehicle with both axles on the
ground (Y page 447) Read the safety instructions on towing and
tow-starting (Y
page 445). All components of the hybrid drive system are
marked with yellow warning stickers that
warn you of the danger of high voltage. The
cables of the vehicle's high-voltage electrical system are orange in colour.
The ignition must be switched off when car-
rying out general work, such as changing
bulbs or checking the coolant level.
Automatic switching off of the hybrid
drive system If components of the restraint system are
activated during an accident, the hybrid drive
system is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
R an electrical short circuit is detected in the
hybrid drive system
R an electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into con-
tact with high voltage.
Manual switching off of the hybrid drive system The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.44

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

When Standard
Standard is selected, no warning
vibration occurs if:
R you have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.
R a driving safety system intervenes, such
as ABS, BAS or ESP ®
.
When Adaptive
Adaptive is selected, no warning
vibration occurs if:
R you have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.
R a driving safety system intervenes, such
as ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane marking, the system detects certain condi-
tions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend
R the road has very wide lanes, e.g. a motor-
way
R the system detects solid lane markings The warning vibration occurs later if:
R the road has narrow lanes
R you cut the corner on a bend
Towing a trailer
If you couple up a trailer, make sure that you have correctly established the electrical con- nection. This can be accomplished by check-
ing the trailer lighting. PLUG
‑IN HYBRID operation Points to remember
General notes Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRIDmode, the hybrid
drive system automatically selects the most
efficient operating mode for every driving sit-
uation. Drive the vehicle in the usual manner.
To save fuel in HYBRIDmode, the hybrid drive
system switches off the combustion engine
as often as possible during the journey when power output requirements are low. When
power output requirements are low, the elec-
tric motor powers the vehicle. When power
output requirements are high, the combus-
tion engine is automatically switched on.
When the vehicle is stationary, the combus-
tion engine is usually switched off. Conse-
quently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion
engine using the power stored in the high-
voltage battery. In addition, the power is used
for partially electric driving, operation of the
electric coolant compressor and to support
the 12 V on-board electrical system. In this
way the hybrid drive helps to reduce your
vehicle's fuel consumption.
Observe the driving tips on plug-in hybrid
operation (Y page 297).286

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
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.
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
