The following exemplary driving situations may
show that:▷Decelerating downhill.▷Deceleration before a red light.
Avoid late or abrupt braking. Instead, deceler‐
ate the vehicle using energy recovery.
Coasting
The electric drive makes it possible to roll with‐
out consuming energy. This driving condition
is referred to as coasting.
Proactive driving reduces energy consumption
and increases the range.
With vehicle rolling, no energy is recovered.
Exemplary traffic situations If a route can be traveled without anticipated
need for braking, it is advantageous to roll.
The following exemplary driving situations may
show that:
▷Rolling on a straight downhill route without
obstacles.▷Coasting on a route without obstacles.
Avoid late or abrupt braking.
Range Extender
Increase range
If the charging state of the high-voltage battery
drops during travel to a minimum value, the
Range Extender starts and supplies the re‐
quired electrical energy for driving on.
The symbol on the charging state indicator
designates a Range Extender reel-on time.
The Range Extender controls its output auto‐
matically, turns itself off and restarts according
to the driving situation.
The high-voltage battery will not be charged
by the Range Extender.
Automatic maintenance run
To ensure that the Range Extender functions
properly even during longer periods of non-
use, the Range Extender is automatically acti‐
vated for a few minutes at certain intervals dur‐
ing the trip. Respective Check Control
messages indicate the dry run. Should that oc‐
cur at an unfavorable time you may cancel the
dry run by pressing the Start/Stop button. It
postpones the dry run.
Should the high-voltage battery be fully
charged or if there is not enough gas in the
tank then a dry run will not be executed.
Heavily discharged high-voltage
battery
If the high-voltage battery is heavily dis‐
charged during the trip, the performance and
some comfort features are reduced step-by-
step to extend the range.
Heated high-voltage battery
With a stationary dirt In exceptional cases, it is possible that the
high-voltage battery heats up sharply when the
vehicle is stationary. E. g. with extreme exter‐
nal temperatures and direct solar radiation.
With a overheated high-voltage battery, drive
readiness cannot be switched on.
A Check Control message is displayed.
Another message will indicate when drive
readiness is available again.
While driving
If the high-voltage battery overheats during the
trip, the performance is reduced step-by-step
in order to cool down the battery. The ePO‐
WER performance display in the instrument
cluster returns in the process. When tempera‐
ture increases further, park the vehicle until the
high-voltage batter has cooled down. Should
the performance display fall to 0, drive readi‐Seite 69DrivingControls69

factured. After installing a child seat, make
sure that the indicator lamp for the front-seat
passenger airbags lights up. This indicates
that the child seat has been detected and the
front-seat passenger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐
er's seat.
With a respective message appearing on Con‐
trol Display calibrate the front seats to keep
the accuracy of this function over the long-
term.
Calibrating the front seats A corresponding message appears on the
Control Display.1.Press the reel and move the respective
seat all the way forward.2.Press the reel forward again. The seat still
moves forward slightly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disap‐
pears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury
or damage to objects.◀
Tire Pressure Monitor TPM
The concept The system monitors tire inflation pressure in
the four mounted tires. The system warns you
if there is a significant loss of pressure in one
or more tires. For this purpose, sensors in the
tire valves measure the tire inflation pressure
and tire temperature.
Hints Tire damage due to external factors
Sudden tire damage caused by external
circumstances cannot be recognized in ad‐
vance.◀
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 173.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display The current status of the Tire Pressure Moni‐
tor TPM can be displayed on the Control Dis‐
play, e.g., whether or not the TPM is active.
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Tire Pressure Monitor (TPM)"

sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.
FTM Flat Tire Monitor The conceptThe system detects tire inflation pressure losson the basis of rotation speed differences be‐
tween the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. This will be
detected and reported as a flat tire.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured. Initialize the system after each correc‐ tion of the tire inflation pressure and after
every tire or wheel change.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"The status is displayed.
Initialization
When initializing the once set inflation tire
pressures serve as reference values in order to
detect a flat tire. Initialization is started by con‐
firming the tire inflation pressures.
Do not initialize the system when driving with
snow chains.
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Switch on drive readiness – do not drive
off.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. If the tire inflation
pressure in all tires is correct, the Flat Tire
Monitor may not have been initialized. In
this case, initialize the system.3.Repair flat tire with the Mobility System, re‐
fer to page 178, or replace the damaged
wheel.
If a Mobility System is not available, contact
the service center.
