Driving on uphill grades G
WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in addi-
tion to shifting to park position P.
! When the hill‑start assist system stops
braking the vehicle, it can roll back-
wards.
If you open the driver’s door, the
hill‑start assist system is deactivated
and a warning signal sounds.
Your vehicle has a hill‑start assist system. On uphill grades the hill‑start assist sys-
tem maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal. There-
fore, you can start off smoothly without the
vehicle moving immediately after releas-
ing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the accel-
erator pedal to drive off.
On uphill grades with higher inclination,
the hill-start assist system will release
the pressure in the brake system after
approximately two seconds. A warning sig-
nal sounds and the transmission position
indicator shows a flashing N
N in order to
warn you of the vehicle rolling backwards.
X Press the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the accel-
erator pedal to drive off. i
The hill‑start assist system is inactive
if you start off with the parking brake
engaged.
Recuperation If the high-voltage battery is fully
charged or too cold, only limited recuper-
ation power will be available.
The vehicle can not be decelerated or limi-
ted in being decelerated by using the
accelerator pedal, if
R the gearshift selector lever is in posi-
tion Dand the vehicle is rolling back-
wards
R the gearshift selector lever is in posi-
tion Rand the vehicle is rolling for-
wards.
On uphill grades, the vehicle could possi- bly be not or only restricted being held

Connecting the vehicle to the Internet Via mobile service module
i This function is only available if the
vehicle is equipped with a mobile ser-
vice module.
You can use the “Vehicle Homepage” when
the vehicle has connected to the Internet
via the mobile service module. The mobile
service module uses GSM (Global System for Mobile Communications) and transfers the
required data via radio transmission. The
vehicle automatically detects if a connec- tion to the Internet via the mobile service module is available or not. No pre-settings
need to be done.
In order to use data transfer via the mobile
service module you do not need a SIM card
and no contract.
i There may be service limitations if the
vehicle is located for example in a
underground garage. Service limita-
tions may also appear in areas with poor
mobile service coverage. In theses cases
you can launch the Internet connection
via powerline (Y page 122).
Via powerline
You can also access the “Vehicle Homepage”
if you do not have GSM reception. This is
possible for example via your DSL router.
This connection is built by the plugged in charging cable with the aid of the power-
line technology.
The vehicle supports powerline communi-
cation according to the "HomePlug AV" standard. Data is transmitted via phase L1
and the neutral conductor of the power line.
In order for the vehicle to access the Inter-net, you require a commercially available
adapter of the "HomePlug AV" standard.
This adapter must also have an encryption
button so that it can be configured to com-
municate with the vehicle. Connect the
adapter to the power supply as well as your Internet connection. If the adapter is con-
nected to different phase than L1, a phase
coupler must be additionally installed.
Only in this way can stable communication
be guaranteed. For questions, consult a
qualified electrician.
i If you already have a powerline network
installed, the vehicle can be integrated
into it.
To establish a connection between the
vehicle and a powerline adapter, carry out
the following:
X Connect the vehicle to a power socket or a
wallbox.
The right #indicator lamp on the
vehicle socket must flash green.
X Insert the powerline adapter into a
neighboring power socket. Observe that
the vehicle and the adapter are connec-
ted via phase L1.
X Switch on the ignition.
X Call up the Charge current
Charge current menu on the
control system (Y page 92).
Carry out the following steps within
30 seconds: X If the value of the charge current is not
set to 8 A:set the value to 8 A and confirm.
X Set the value of the charge current to 12 A
and confirm.
X Set the value of the charge current to 8 A
and confirm. 122
High-voltage battery>> Operation.
X
Set the value of the charge current to 12 A
and confirm.
X Press the encryption button on the pow-
erline adapter within three minutes.
When the powerline adapter shows a con-
nection, the connection process was suc- cessful.
i Observe the separate operating
instructions of the powerline adapter.
i Contact an authorized electric drive
smart center if you have any questions.
X Next, set the value of the charge current
to the desired value once again.
As soon as the vehicle establishes an Inter- net connection, you can also use the "Vehi-
cle Homepage" at home during the charging process. Changes you have made via the
"Vehicle Homepage" are adopted after the
charging process is complete. This data
transmission ends after approximately
three days. Intelligent charging management
If you wish to charge economically and with
minimal damage to the battery, you must set a departure time (Y page 90). This option to
optimize the charging process depends on
your electricity contract and the local
power supplier. Your vehicle detects this
option automatically. Depending on the
departure time which is set, the charging
process of the high-voltage battery may not be started immediately or may be inter-
rupted during the process. Front compartment
Service flap
Remove the service flap to check the bat-
tery coolant level, windshield washer res- ervoir level, and brake fluid level. Insert the service flap on the front of the
vehicle so that it does not get damaged or
dirty.
i
The service flap has a strap on the rear
side that ties it to the vehicle body. G
WARNING
Always turn the key to starter switch posi-
tion 0and remove the key from the starter
switch before opening the service flap.
If the windshield wipers should inadver-
tently be switched on, you could be seri-
ously injured by the wiper washer drive,
which is located just below the service
flap. G
WARNING
Make sure the service flap is locked while
driving. Otherwise, the service flap could
become detached and pose a hazard to you or others.
! Check the fill levels at regular inter-
vals.
! Carefully remove ice, snow, and any
other deposits from the air intake
grilles above the service flap to ensure
air intake at all times.

TPMS to continue to function properly.
i If a condition causing the TPMS to mal-
function develops, it may take up to
10 minutes for the system to signal a mal-
function using the TPMS telltale flash-
ing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunction.

WARNING
It is the driver’s responsibility to cali-
brate the TPMS on the recommended cold
inflation pressure. Underinflated tires
affect the ability to steer or brake and
might cause you to lose control of the vehi- cle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of different load or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
X Using the Tire and Loading Information
placard on the driver’s door B‑pillar
(Y page 133), make sure the tire infla-
tion pressure of all four tires is correct.
i Restart the TPMS after adjusting the
tire inflation pressure to the inflation
pressure recommended for the vehicle
operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire inflation
pressure on the Tire and Loading Infor-
mation placard on the driver’s door
