Notes
For information on voice control of the 
telephone, refer to page177.<
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 
speaking. {Voice commands}

instance if an attempt is made to jack it up 
and steal the wheels or to raise it prior to 
towing away
>When there is an interruption in the power 
supply from the battery
The alarm system signals unauthorized entry 
attempts for a short time by means of:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams 

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.

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.
