▷There are hybrid system faults.
Safety mode
The combustion engine does not start automat‐
ically in the following situations after an auto‐
matic engine stop:
▷When the driver's door is open and neither
the brake nor accelerator pedal are de‐
pressed.▷When the hood is unlocked.
The indicator lamps come on. The combustion
engine can only be started via the Start/Stop
button.
Switching off the vehicle during an
automatic engine stop
During an automatic engine stop, the vehicle
can be switched off permanently, e.g., when
leaving it.
1.Press the Start/Stop button. The ignition is
switched off. The Auto Start/Stop function
is deactivated.
Transmission position P is engaged auto‐
matically.2.Set the parking brake.
Malfunction
The Auto Start/Stop function no longer
switches of the engine automatically in the event
of a malfunction. A message is displayed. It is
possible to continue driving. Have the system
checked.
Electric driving: eDRIVE
Requirements
Electric driving is possible under the following
conditions:
▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
In addition, the combustion engine is switched
off during braking even below 50 mph, approx.
80 km/h or when coasting below 35 mph, ap‐
prox. 60 km/h.
In ECO PRO mode, already when coasting be‐
low 100 mph, approx. 160 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can generally be driven us‐
ing electric power up to 2 miles, approx. 3.5 km.
Driving with the combustion
engine: DRIVE
The combustion engine provides the drive
power to propel the vehicle. The high-voltage
battery is charged at the same time.
Automatic start while driving
The combustion engine is automatically started
under the following conditions while driving:
▷Transmission position M/S is engaged.▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery charge is insuffi‐
cient or it is fully charged, such as when driv‐
ing downhill.▷The required power output is increased,
such as due to the accelerator pedal position
or driving uphill.Seite 67DrivingControls67

Automatic stopping while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 67, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
drive power to move the vehicle.
The electric motor provides assistance as
needed with additional propulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST
Accelerating quickly, such as when passing, re‐
quires the maximum available power from the
electric motor. To do this, apply extra force to
the accelerator pedal.
Energy recovery: CHARGE
The hybrid system makes it possible to convert
kinetic energy into electrical power, such as
when braking. This recovered energy charges
the high voltage battery. If necessary, this stored
power is output to the electric motor.
The following conditions must be met to recover
kinetic energy:▷The vehicle is moving.▷Selector lever position D, M/S is engaged.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument clus‐
ter, refer to page 81.
Parking brake
The concept
The parking brake is primarily intended to pre‐
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Setting
Pull the switch.
The LED lights up.
The indicator lamp lights up red. The
parking brake is set.
Lower lamp: indicator lamp in Canadian
models
Set the parking brake and further secure
the vehicle as required
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the vehi‐
cle, for example, by turning the steering wheel in
the direction of the curb. ◀
While driving
Use while driving serves as an emergency brak‐
ing function:
Pull the switch and hold it. The vehicle brakes
hard while the button is being pulled.

The indicator lamp lights up red, a signal
sounds and the brake lamps light up.
Lower lamp: indicator lamp in Canadian

If the vehicle is braked to a speed of approx.
2 mph/3 km/h, the parking brake remains set.
Releasing
With the ignition switched on:
Automatic transmission: Press the switch
while the brake is pressed or transmission
position P is engaged.
The LED and indicator lamp go out.
The parking brake is released.
Automatic Release in cars with
automatic transmission
For automatic release, operate the accelerator
pedal.
The LED and indicator lamp go out.
Subject to the following requirements, the park‐
ing brake is automatically released by operation
of the accelerator pedal:▷Drive readiness on.▷Drive position engaged.▷Driver buckled in and doors closed.
Inadvertent operation of the accelerator
pedal
Make sure that the accelerator pedal is not op‐
erated unintentionally; otherwise, the vehicle is
set in motion and there is a risk of an accident. ◀
Automatic Hold
The concept
This system assists the driver by automatically
setting and releasing the brake, such as when
moving in stop-and-go traffic.
The vehicle is automatically held in place when
it is stationary.
On inclines, the system prevents the vehicle
from rolling backward when driving away.
For your safety
Under the following conditions, Automatic Hold
is automatically deactivated and the parking
brake is set:
▷The engine is switched off.▷A door is opened and driver's safety belt is
unbuckled while the vehicle is stationary.▷The moving vehicle is brought to a standstill
using the parking brake.
The indicator lamp switches from green
to red and the letters AUTO H go out.
Lower lamp: indicator lamp in Canadian

Leaving the vehicle with the engine run‐
ning
Before leaving the vehicle with the engine run‐
ning, engage position P of the automatic trans‐
mission and ensure that the parking brake is set.
Otherwise, the vehicle may begin to roll.◀
Activating
This function can be activated when the driver's
door is closed and the safety belt is fastened,
and while driving.

matically secured against rolling when it stops.
The indicator lamp lights up green.
Step on the accelerator pedal to drive
off.
The brake is released automatically.
The indicator lamp goes out.
Lower lamp: indicator lamp in Canadian models
Before driving into a car wash
Deactivate Automatic Hold; otherwise, the
parking brake will be set when the vehicle is sta‐
tionary and the vehicle will no longer be able to
roll.◀
Parking
The parking brake is automatically set if the en‐
gine is switched off while the vehicle is being
held by Automatic Hold.
The indicator lamp changes from green
to red.
The parking brake is not set if the engine
is switched off while the vehicle is coast‐
ing to a halt. Automatic Hold is deacti‐
vated.

Washer fluid
General information Antifreeze for washer fluid
Antifreeze is flammable. Therefore, keep
it away from sources of ignition.
Only keep it in the closed original container and
inaccessible to children.
Follow the instructions on the container.◀
Washer fluid reservoir Adding washer fluid
Only add washer fluid when the engine is
cool, and then close the cover completely to
avoid contact between the washer fluid and hot
engine parts.
Otherwise, there is the danger of fire and a risk
to personal safety if the fluid is spilled.◀
All washer nozzles are supplied from one reser‐
voir.
Fill with water and – if required – with a washer
antifreeze, according to the manufacturer's rec‐
ommendations.
Mix the washer fluid before adding to maintain
the correct mixing ratio.
For the capacity, refer to technical data.
