Retrieving the seat, mirror, and
steering wheel settings
The driver's seat, exterior mirror, and steering
wheel position adjusted last will be stored for
the active profile.
When the vehicle is unlocked, these positions
are automatically retrieved if this function was
activated.
Pinch hazard when moving back the seat
If this function is used, first make sure
that the footwell behind the driver's seat is
empty. Otherwise, people might get injured or
objects damaged when the seat is moved
back.◀
The adjustment procedure is interrupted:
▷When a seat position reel is pressed.▷When a button of the seat, mirror, and
steering wheel memory is pressed briefly.

The conceptWhen the vehicle is locked, the vehicle alarm
system responds to:▷Opening a door, the hood or the trunk lid.▷Movements in the interior.▷Changes in the vehicle tilt, e. g., during at‐
tempts at stealing a wheel or when towing
the car.▷Disconnected battery voltage.
The alarm system briefly signals tampering:
▷By sounding an acoustic alarm.▷By switching on the hazard warning sys‐
tem.▷By flashing the daytime running lights.
Arming and disarming the alarm
system
When you unlock or lock the vehicle, either
with the remote control, Comfort Access or at
the door lock the alarm system is disarmed or
armed at the same time.
Door lock and armed alarm systemUnlocking via the door lock will trigger the
alarm on some country-specific versions.
Trunk lid and armed alarm system The trunk lid can be opened even when the
alarm system is armed.
After the trunk lid is closed, it is locked and
monitored again when the doors are locked.
The hazard warning system flashes once.
Panic mode
You can trigger the alarm system if you find
yourself in a dangerous situation.
Press button on the remote control for
at least 3 seconds.
To switch off the alarm: press any button.

Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differ‐
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are
longer and the self-steering properties will
change.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving and contact your service
center.◀
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 thetire 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 206.
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)"
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.

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 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 212, 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.◀
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 gage of the Mobility Sys‐
tem, refer to page 212, can possibly be
used for this purpose.Seite 119SafetyControls119
