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 auto‐
matically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings dur‐
ing unlocking. These settings are also restored,
if the vehicle has been used in the meantime
by a person with a different remote control.
Changes to the settings are automatically saved
in the personal profile.

Washer/wiper system
Switching the wipers on/off and brief
wipe
General information Do not use the wipers if the windshield is dry,
as this may damage the wiper blades or cause
them to become worn more quickly.
Information CAUTION
If the wipers are frozen to the windshield,
the wiper blades can be torn off and the wiper
motor overheat on switching on. There is risk of
property damage. Defrost the windshield prior
to switching the wipers on. ◀
WARNING
If the wipers start moving in the folded
away state, damage may occur to parts of the
vehicle or body parts can be jammed. There is
risk of injuries or risk of property damage. Make
sure that the vehicle is switched off when the
wipers are in the folded away state and the
wipers are folded in when switching on. ◀
Switching on
The lever automatically returns to its initial po‐
sition when released.
▷Normal wiper speed: tap up once.
The wipers switch to intermittent operation
when the vehicle is stationary.▷Fast wiper speed: tap up twice or tap once
beyond the resistance point.
Wipers change to normal speed when vehi‐
cle comes to standstill.
Switch off and brief wipe
The lever automatically returns to its initial po‐
sition when released.
▷Single wipe: press down once.▷To switch off from normal wiper speed:
press down once.▷To switch off from fast wiper speed: press
down twice.
Interval mode or rain sensor
The concept
Without the rain sensor, the frequency of the
wiper operation is preset.
The rain sensor automatically controls the time
between wipes depending on the intensity of
the rainfall. The sensor is located on the wind‐
shield, directly behind the interior rearview mir‐
ror.

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 in‐
flation 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.
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 187, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Ob‐
serve the information on run-flat tires and con‐
tinued driving with these tires. ◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tireNormal tires
1.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 188, 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 identification of flat tire damage is not
possible, please contact a dealer’s serviceSeite 85SafetyCONTROLS85

FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
It detects a tire inflation pressure loss by com‐
paring the rotational speeds of the individual
wheels while moving.
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.
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, e.g., whether the RPA is active.1. Press button.2. "Vehicle Info"3."Vehicle status"4."Flat Tire Monitor (FTM)"
The status is displayed.
Initialization When 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
normal tires or run-flat tires.
Run-flat tires, refer to page 187, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Ob‐
serve the information on run-flat tires and con‐
tinued driving with these tires. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
