Emergency detection of remote
control
It is possible to switch on the ignition or start
the engine in situations such as the following:
▷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.
Starting the engine with emergency
detection of the remote control
If a respective Check Control message ap‐
pears, hold the remote control with its back
against the marked area on the steering col‐
umn. The tailgate button on the remote control
should be at the same height as the marked
area. Press the Start/Stop button within
10 seconds while pressing the brake pedal.
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.

Launch Control
The concept Launch Control enables optimum accelerationon surfaces with good traction.
General information
The use of Launch Control causes premature
component wear since this function represents
a very heavy load for the vehicle.
Do not use Launch Control during the break-in,
refer to page 188, period.
To increase vehicle stability, activate DSC
again as soon as possible.
An experienced driver may be able to achieve better acceleration values in DSC OFF mode.
Requirements Launch Control is available when the engine is
warmed up, that is, after uninterrupted driving
of at least 6 miles/10 km.
To start with Launch Control do not steer the
steering wheel.
Start with launch control
While the engine is running:1. Press button or select Sport+ with
the Driving Dynamics Control.
TRACTION is displayed in the instrument
cluster and the indicator lamp for DSC OFF
lights up.2.Engage selector lever position S.3.With the left foot, forcefully press down on
the brake.4.Press and hold down the accelerator pedal
beyond the resistance point at the full
throttle position, kickdown.
A flag symbol is displayed in the instru‐
ment cluster.5.The starting engine speed adjusts. Within
3 seconds, release the brake.
Before using Launch Control, allow the trans‐
mission to cool down for approx. 5 minutes.
Launch Control adjusts to the surrounding
conditions, e.g., wet pavement, when used
again.

Status displayThe 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)"
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
reset".6.Drive away.
The wheels are displayed in gray and the sta‐
tus 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.
The progress of the reset is displayed.
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
normal tires or run-flat tires.Seite 110ControlsSafety110

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
