Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.
iRead the information on qualified specialist
workshops (Ypage 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
GDANGER
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.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle'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:
RTransporting the vehicle (Ypage 381)
RTowing a vehicle with both axles on the
ground (Ypage 380)
Read the safety instructions on towing and tow-
starting (
Ypage 379).
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 color.
The ignition must be switched off when carrying
out general tasks, such as adding washer fluid to
the windshield washer system or checking the
coolant level.
Automatic switching off of the hybrid
drive system
If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
Ran electrical short circuit is detected in the
hybrid drive system
Ran electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
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.
!To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions:
Ronly deactivate the hybrid drive system
manually in the following situations.
Rwork on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.

Problems with the engine
ProblemPossible causes/consequences andMSolutions
The engine does not
start. The starter motor
can be heard.RThere is a malfunction in the engine electronics.
RThere is a malfunction in the fuel supply.
Before attempting to start the engine again:
XTurn the SmartKey back to position 0in the ignition lock.
or
XPress the Start/Stop button repeatedly until all indicator lamps in
the instrument cluster go out.
XTry to start the engine again (Ypage 164). Avoid excessively long
and frequent attempts to start the engine as these will drain the
battery.
If the engine does not start after several attempts:
XConsult a qualified specialist workshop.
The engine does not
start. You cannot hear
the starter motor.The on-board voltage is too low because the battery is too weak or
discharged.
XJump-start the vehicle (Ypage 376).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.
The starter motor was exposed to a thermal load that was too high.
XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
gauge shows a value
above 248 ‡ (120 †).The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 356). Observe the warning notes
as you do so and add coolant if necessary.

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 effi-
cient operating mode for every driving situation. 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 out-
put requirements are low, the electric motor
powers the vehicle. The combustion engine is
automatically activated when power output
requirements are high. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, 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 bat-
tery. 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
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on PLUG-IN HYBRID
operation (
Ypage 251).
Recuperative Brake System
If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (
Ypage 44).
Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
Ra message appears in the multifunction dis-
play and
Ra warning tone sounds
Further information (
Ypage 297).
All of the vehicle's systems remain active, if:
Rthe vehicle is stationary
Rthe combustion engine is switched off and
Rthe READY indicator in the instrument cluster
lights up
If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
may pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function (
Ypage 252).
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations.
Depending on the vehicle's equipment and
country-specific regulations, the vehicle can be
equipped with Acoustic Vehicle Indication.
Acoustic Vehicle Indication generates a certain
sound at a speed between 0 and 19 mph
(30 km/h). This helps other road users, partic-
ularly pedestrians and cyclists, to hear your
vehicle better. The sound can also be heard
inside the vehicle.
The volume depends on the engine speed. The
faster you accelerate, the louder the sound is. At
a speed of over 19 mph (30 km/h) the sound is switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.
