For voice commands, bear in mind the follow-
ing:
>Do not use the voice activation system to
initiate an Emergency Request. In stressful
situations, the voice and vocal pitch can
change. This can unnecessarily delay the
establishment of a telephone connection.
>Pronounce the commands and digits
smoothly and at normal volume, avoiding
excessive emphases and pauses. This also
applies when spelling out and saying a full
word during destination entry.
>When selecting a radio station, use the
standard pronunciation of the station name.
>For entries in the voice-activated phone
book, only use names in the language of the
voice activation system and no abbrevia-
tions.
>Keep the doors, windows and glass roof
closed to prevent interference from outside
noise.
>Avoid ambient noise in the vehicle while

Driving
64 personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you. Otherwise driving situations could result
that pose the risk of accidents.<

Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
greater than approx. 35 mph/60 km/h.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable due to exces-
sive brake temperature, or DSC has failed.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off
assistant will no longer hold the car in place after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<

Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.
Green
The tire inflation pressure corresponds to the
established target value.
"TPM active" appears on the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on
the Control Display.
All wheels yellow
There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the
Control Display.
Gray
The system cannot detect a puncture.
Possible reasons for this:
>TPM is being reset
>Temporary malfunction caused by systems
or devices using the same radio frequency
>Malfunction
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
iDrive, for operating principle refer to page16.
1."Vehicle Info"
2."Vehicle status"
3."Reset TPM"
4.Start the engine - do not drive away.
5.Start the initialization using "Reset TPM".
6.Start to drive.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The system reset is
completed during your drive, and can be inter-
rupted at any time. When driving resumes, the
reset is continued automatically. On the Control
Display, the tires are shown in green and
"Status: TPM active" is displayed again.
