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 switch on the ignition or start
the engine or activate engine readiness.

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 Personal Profile provides three profiles, using
which personal vehicle settings can be stored.
Every remote control has one of these profiles
assigned.
If the vehicle is unlocked using a remote con‐
trol, the assigned personal profile will be acti‐
vated. All settings stored in the profile are au‐
tomatically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings
during unlocking. These settings are also re‐

The status is displayed.
Status control display Tire and system status are indicated by the
color of the wheels and a text message on the
Control Display.
All wheels green System is active and will issue a warning rela‐
tive to the tire inflation pressures stored during
the last reset.
One wheel is yellow A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow A flat tire or major drop in inflation pressure in
several tires.
Wheels, gray The system cannot detect a flat tire. Reasons
for this may be:
▷The system is being reset.▷Malfunction.
Status information
The status control display additionally shows
the current tire inflation pressures and, de‐
pending on the model, tire temperatures. It
shows the actual values read; they may vary depending on driving style or weather condi‐
tions.
Carry out reset Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
On the Control Display and on the vehicle:1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive off.5.Reset tire inflation pressure:"Perform

The tires are shown in gray and the status is
displayed.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The reset is
completed automatically while driving.
After a successfully completed Reset, the
wheels on the Control Display are shown in
green and "Tire Pressure Monitor (TPM)
active" is displayed.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
Low tire pressure message 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.▷No reset was performed for the system.
The system therefore issues a warning
based on the tire inflation pressures before
the last reset.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 198, are la‐

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.Start the engine - 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.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 198, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀

General information
The image is lidtured by two cameras
integrated in the exterior mirrors and by the
rearview camera.
The range is at least 7 ft/2 m to the side and
rear.
In this way, obstacles up to the height of the
exterior mirrors are detected early.
Hints Check the traffic situation as well
Check the traffic situation around the ve‐

dent could result from road users or objects
that are not lidtured by the camera.◀

During a slight deceleration by gently pressing
the brake pedal.
Maximum energy recovery:
During firmer pressing on the brake pedal.
Foresighted driving and decelerating helps
with optimizing energy recovery.

Exemplary traffic situations for fuel
efficiency
In many driving situations, the hybrid system
allows for a particularly efficient energy man‐
agement.▷Stop-and-go traffic:
The combustion engine is switched on or
over automatically by the hybrid system.▷Driving with constant speed:
With the ASSIST acceleration support, the
electric motor relieves the combustion en‐
gine periodically by being switched on au‐
tomatically.
Discharge of the high-voltage battery
In normal operation, a sufficient charging of the
high-voltage battery is ensured by energy re‐
covery.
Longer idle periods can reduce the charge
state of the high-voltage battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. If necessary, charge the high-voltage
battery by driving the vehicle. Check the
charge level regularly, and if needed recharge
the high-voltage battery by driving the vehicle.
Don't allow battery charge status to drop too
low - it will damage the battery.◀
Charging by driving
In order to charge the high-voltage battery
most effectively when driving, activated the
transmission's Sport program DS, refer to
page 78.
