mote control by external sources e.g., by
radio masts.▷Empty battery in remote control.▷Interference from radio transmissions
through mobile devices in close proximity
to remote control.▷Interference of radio transmission by
charger while charging items such as mo‐
bile devices in the vehicle.
A Check Control message is displayed if an at‐
tempt is made to reel on the ignition or start
the engine or activate engine readiness.

DrivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Start/Stop button, drive
readiness
The concept The following ready states can
be attained by pressing the
Start/Stop button:▷Radio ready state on/off.▷Ignition on/off.▷Activating/deactivating drive readiness.
To activate drive readiness, press the brake
pedal.
Switching radio-ready state on/off
The radio-ready state is activated by pressing
the Start/Stop button in the following situa‐
tions:
▷When the engine is running.▷When drive readiness is activated.▷When the engine is switched off automati‐
cally using the Auto Start/Stop function
and the brake is not applied.
Some electronic systems/power consumers
remain ready for operation.
Radio ready state is switched off automatically:
▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
Ignition on
Press the Start/Stop button, and do not press
on the brake pedal at the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lights in the
instrument cluster light up for a varied length
of time.
To save battery power when the engine is off,
reel off the ignition and any unnecessary elec‐
tronic systems/power consumers.
Note If the engine is switched off and the ignition is
switched on, the system automatically
switches to the radio-ready state with doors
open and the lights switched off or the daytime
running lights switched on.
Ignition off
Press the Start/Stop button again, and do not
press on the brake pedal at the same time.
All indicator lights in the instrument cluster go
out.
To save battery power when the engine is off,
reel off the ignition and any unnecessary elec‐
tronic systems/power consumers.
P when the ignition is switched off
P is engaged automatically when the ig‐
nition is switched off. When in an automatic car wash, e.g., ensure that the ignition is not
switched off accidentally.◀
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:
Seite 67DrivingControls67
Online Edition for Part no. 01 40 2 956 725 - X/14
▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available
when the low beams are turned off.▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
The low beams reel to parking lights after ap‐
prox. 15 minutes of no use.
When the ignition is switched off automatically
by opening or closing the driver's door, un‐
buckling the driver's safety belt or by the auto‐
matic switching of the low beams to parking
lights, the radio-ready state remains active.
Drive readiness
When drive readiness is activated, the vehicle
is operational. Activated drive readiness is the
equivalent of a running engine in conventional
vehicles. Deactivated engine readiness is
equivalent to switching the ignition off.
Drive readiness in detail
The concept
The following are the different drive readiness
variants:
▷Electric drive readiness, Silent Start, refer
to page 68
The vehicle is powered by the electric mo‐
tor.▷Starting the combustion engine, refer to
page 68
The vehicle is powered by the combustion
engine.Hints
Do not leave the vehicle unattended
Do not leave the vehicle unattended with
drive readiness active; otherwise, it may pose a
risk.◀
Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that due to
the lack of engine noise pedestrians and other traffic might pay less attention to the vehicle
due to missing engine noises. Please take spe‐
cial care when parking or leaving a parking
space.◀
Activating drive readiness1.Close the driver's door.2.Depress the brake pedal.3.Press the Start/Stop button.
Drive readiness is activated:
▷Electric drive readiness, Silent Start or▷Starting the combustion engine.
Electric drive readiness, Silent Start The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 70, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀

Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in selector lever position P or N to pre‐
vent the vehicle from moving.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
The combustion engine is started with Acti‐
vate drive, refer to page 68, readiness under
the following conditions:▷The drive system is not at operating tem‐
perature.▷The temperature of the hybrid system is
too high.▷The high-voltage battery has an insuffi‐
cient charge.
Driving away
1.Activate drive readiness.2.Engage selector lever position D, M/S or R.3.Release the parking brake.4.Drive away.
Deactivating drive readiness
After stopping the vehicle:
1.Engage selector lever position P.2.Press the Start/Stop button.3.Set the parking brake.
After parking the vehicle, you may hear noises
due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
Hints
Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, e.g., can‐
not start the engine.◀
Apply parking brake and further secure
the vehicle if needed.
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the ve‐
hicle, e.g., by turning the steering wheel in the
direction of the curb.◀
Before driving into a car wash So that the vehicle can roll into a car wash ob‐
serve instructions for going into an automatic
car wash, refer to page 223.
Auto Start/Stop function
The concept The Auto Start/Stop function helps save fuel.
The system switches off the combustion en‐
gine when conditions for electric driving have
been met. The ignition or drive readiness re‐
mains switched on.
READY appears on the tachometer. If neces‐
sary, the combustion engine starts automati‐
cally.
The combustion engine is also stopped during
the trip when coasting or braking. This driving
condition, in which the vehicle is traveling with‐
out power and energy recovery is not active, is
referred to as coasting, refer to page 70.
Note
The combustion engine is not switched off au‐
tomatically in the following situations:▷The combustion engine is not at operating
temperature.Seite 69DrivingControls69
