2013 BMW 3 SERIES CONVERTIBLE snow chains

Addendum
determine if they are suitable for
use on your vehicle.
You can inquire about the
recommended wheel/tire
combination at your BMW center.
The recommended combination of
wheels and tires will help ensure
reliable operation of various vehicle
systems such as ABS, DSC or FTM.
To maintain good handling and
vehicle response, BMW
recommends that you use tires of a
single brand and tread
configuration. After a tire has been
damaged, mount the previous
wheel and tire combination again as
soon as possible.
11.At page 254, under the heading:
“Snow Chains,” the text should be
disregarded and the following text
should be read in lieu thereof:
Only certain types of fine-link snow
chains have been tested by the
manufacturer of your vehicle and
are determined by the manufacturer
of your vehicle to be road safe and
are recommended by the
manufacturer of your vehicle.
Information about recommended
snow chains is available from a
service center.
12.At page 255, under the heading
“Hood,” the sentence beginning “If
you are not familiar . . .” should be
disregarded and the following text
should be read in lieu thereof: “If
this work is not carried out properly,
there is a danger of subsequent
damage and related safety
hazards.”
13.At page 259, under the heading:
“Approved oil grades,” the
references to “Approved” should be
read as “Suitable.” Immediately
preceding the “Gasoline engine”
chart, the following sentence should
be inserted: “Add engine oils that
meet the following oil rating
standards: . . .” The reference to
“BMW High Performance SAE 5W-
30” should be disregarded.
14.At page 259, under the heading:
“Alternative oil types,” the text
preceding the chart should be
disregarded, and in lieu thereof
should be read as follows: “If an
engine oil suitable for continuous
use is not available, up to 1 US
quart/liter of an engine oil with the
following oil rating can be added: . .
.” The reference to “specification”
should be read as “rating.”
15.At page 259, under the heading:
“Oil change,” the text should be
disregarded and in lieu thereof
should be read as follows:
BMW recommends that you have
the oil changed at your BMW
dealer’s service center or at another
service center that has trained
personnel that can perform the work
in accordance with BMW
specifications

ControlsTechnology for driving comfort and safety
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident. <
Deactivating DSC
Press the button for at le ast 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster.
Dynamic Traction Control DTC and DSC have
been simultaneously de activated. Stabilizing
and drive-output promoting actions are no
longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed to enhance drive output if the
drive wheels experience a significant loss of
traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; th e indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for part icular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following sp ecial circumstances:
> When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains
Activating DTC
Press the button; the indicator lamp for DSC
OFF lights up and TRACTION is displayed in
the instrument cluster.
For better control
If the indicator lamp flashes: DTC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and TRAC-
TION is displayed in the instrument
cluster: DTC is activated.
Deactivating DTC
Press the button again; th e indicator lamp in the
instrument cluster goes out.

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. Ot herwise, 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 system does not measure the actual
inflation pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Each time a tire inflation pressure has been
corrected or a wheel or tire has been changed,
reinitialize the system.
System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, steady pressure loss in all four tires is
not detected. Therefore, check the tire inflation
pressure regularly.
In the following situatio ns, 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, hi gh lateral acceleration
> Snow chains are attached
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.
1."Vehicle Info"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the syst em when driving with
snow chains.

Snow chains
Only certain fine-link sn ow chains have been
tested by BMW, classifi ed as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Fl at Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page 98.<
