Emergency detection of remote
control
Also in one of the following situations, the igni‐
tion can be switched on, engine started or
drive readiness activated:
▷Interference of radio transmission to re‐
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.
Starting the engine or activating drive
readiness with emergency detection
of the remote control
Steptronic transmission: if a corresponding
Check Control message appears, hold the re‐
mote control, as shown, against the marked
area on the steering column and press the
Start/Stop button within 10 seconds while
pressing the brake.
If the remote control is not recognized: slightly
change the height position of the remote con‐
trol and repeat the procedure.
Personal Profile
The concept Individual settings in the vehicle are saved in
personal profiles. Every remote control is as‐
signed the last active profile.
Three personal profiles and a guest profile can
be created.
▷Changes to the settings are automatically
saved in the profile currently activated.▷Unlocking the car activates the profile that
is stored in the remote control.Seite 37Opening and closingControls37

▷Trunk lid secured, arrow 1.▷Trunk lid not secured, ar‐
row 2.
Slide the reel into the arrow 1 position. This
secures the trunk lid and disconnects it from
the central locking system.
This is beneficial when the vehicle is parked
using valet service. The infrared remote con‐
trol can be handed out without the key.
Emergency unlocking
Pull the handle inside the cargo area.
The trunk lid unlocks.
Comfort Access
The concept The vehicle can be accessed without activat‐
ing the remote control.
All you need to do is to have the remote con‐ trol with you, such as in your pants pocket.
The vehicle automatically detects the remote
control when it is in close proximity or in the
car's interior.
Comfort Access supports the following func‐
tions:
▷Unlocking/locking of the vehicle.▷Convenient closing.▷Open the trunk lid individually.▷Open trunk lid with no-touch activation.▷Open/close trunk lid with no-touch activa‐
tion.▷Start the engine.
Functional requirements
▷There are no external sources of interfer‐
ence nearby.▷To lock the vehicle, the remote control
must be located outside of the vehicle.▷The next unlocking and locking cycle is not
possible until after approx. 2 seconds.▷The engine can only be started if the re‐
mote control is in the vehicle.
Unlocking
Grasp the handle of a vehicle door completely,
arrow.
This corresponds with pressing the button on
the remote control.
Locking
Touch the surface on the handle of a vehicle
door, arrow, with your finger for approx. 1 sec‐
ond without grasping the door handle.

What reduces the restraining effect
Avoid wearing bulky clothing, and pull
the shoulder belt periodically to readjust the
tension. Make sure that the belt is not jammed;
otherwise, the belt can be damaged and the
restraining effect is reduced.◀
Buckling the belt
Make sure you hear the latch plate engage in
the belt buckle.
Tensioning the safety belt
automatically
When the belt is closed, it is automatically
tightened once after the release.
Unbuckling the belt
1.Hold the belt firmly.2.Press the red button in the belt buckle.3.Guide the belt back into its roll-up mecha‐
nism.
Safety belt reminder for driver's and
passenger's seat
The indicator lamp lights up and a sig‐
nal sounds. Make sure that the safety
belts are positioned correctly. The
safety belt reminder is active at speeds above
approx. 6 mph/10 km/h. It can also be activated
if objects are placed on the front passenger
seat.
Safety mode
In critical situations, e.g., during full brake ap‐
plication, the front safety belts tighten auto‐
matically.
If the situation passes without an accident oc‐
curring, the belt tension relaxes.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
Damage to safety beltsWear and tear after accidents or when dam‐
aged otherwise:
Have the safety belts, including the safety belt
tensioners, replaced and have the belt anchors
checked.
Check and replace safety belts
This should only be done by your service
center; otherwise, this safety feature might not
work properly.◀
Front head restraints Correctly adjusted head restraint
A correctly adjusted head restraint reduces the
risk of injury to cervical vertebrae in the event
of an accident.
Adjusting the head restraint
Adjust the head restraints of all occupied
seats properly; otherwise, there is an increased
risk of injury in an accident.◀
Height
Adjust the head restraint so that its center is
approximately at ear level.
Distance Adjust the distance so that the head restraint
is as close as possible to the back of the head.Seite 60ControlsAdjusting60

Safety mode
An automatically stopped combustion engine
does not start independently when:
▷The driver's door is open and neither the
brake nor accelerator pedal are depressed.▷Unlocked hood.
The indicator lights come on. The combustion
engine can only be started via the Start/Stop

Electric driving: eDRIVE
Requirements Electric driving is possible:▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is set.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
Possible up to speed of approx. 35 mph, ap‐
prox. 60 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can be driven using electric
power constantly for up to 2-2.5 miles/3-4 km.
CoastingThe combustion engine is automatically stop‐
ped and disengaged from the drive train. This
driving condition is referred to as coasting.
Requirements Coasting is possible:
▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is set.▷The drive system is at operating tempera‐
ture.▷The driver's door is closed.▷In COMFORT mode: when rolling at
speeds exceeding 35 mph, approx.
60 km/h or when braking at speeds above
50 mph, approx. 80 km/h.▷In ECO PRO: mode, when coasting, with‐

Displays of the hybrid
system
Displays in the instrument cluster
The concept The following functions of the hybrid system
are displayed:
▷High-voltage battery charge indicator, refer
to page 86.▷Electric driving: eDRIVE.▷Acceleration boost: eBOOST.▷Energy recovery: CHARGE.▷Auto Start/Stop function and active drive
readiness: READY.
The display depends on the system's operat‐
ing condition.
Note High voltage
Even if no bars are displayed in the bat‐
tery symbol, the high-voltage system is still under high voltage.◀
High-voltage battery charge indicator
When drive readiness is switched on in COM‐
FORT mode, displays the available charge of
the high-voltage battery with bars in a battery
symbol. If five bars are shown, the high-voltage
battery is fully charged.
During normal vehicle operation, the high-volt‐
age battery is charged up to approx. 80 %.
This ensures optimum energy recovery when
braking or driving downhill.
Electric driving: eDRIVE
When driving in COMFORT or ECO PRO
modes, the power output of the electric motor
is indicated by arrows on the instrument clus‐
ter.
Depending on the position of the accelerator
pedal, up to four arrows are displayed simulta‐
neously. The tachometer pointer stays on 0
rpm.
If all four arrows are already displayed, the
combustion engine is switched on, e.g., during
accelerations or on uphill gradients.
