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 via emergencydetection 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.
Manual transmission: if a corresponding Check
Control message appears, hold the remote con‐
trol, as shown, against the marked area on the
steering column and press the Start/Stop but‐
ton within 10 seconds while pressing the
clutch.
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.

Hints Use while driving
On rare occasions if it is necessary to use
the parking brake while driving, do not use ex‐
cessive force when applying it. When using it,
keep the button on the lever depressed.
Otherwise, using excessive force when applying
the parking brake may cause the rear wheels to
lock, resulting in fishtailing. ◀
To prevent corrosion and one-sided brake ac‐
tion, lightly apply the parking brake periodically
while coasting, if traffic conditions permit.
The brake lights will not light up if the parking
brake is set.

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.▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.1.Reduce your speed and stop cautiously.

regular tires or run-flat tires.
Run-flat tires, refer to page 184, are la‐
beled with a circular symbol containing the

Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 185, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Fix the flat tire using the Mobility System,
refer to page 185.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In this
case, have the electronics checked at the next
opportunity and have them replaced if needed.
Run-flat tires Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.Seite 82CONTROLSSafety82
Online Edition for Part no. 01 40 2 961 140 - II/15
InitializationWhen initializing the once set inflation tire pres‐
sures serve as reference values in order to de‐
tect a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.1. Press button.2. "Vehicle Info"3."Vehicle status"4."Flat Tire Monitor (FTM)"5.Start the engine - do not drive off.6.Start the initialization with "Flat Tire
Monitor (FTM) reset".7.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 184, 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. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized in
advance. ◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
