BMW 2011 135i Coupe Manual Do Proprietário

chnology for

driving comfort

and

safe

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 lamps for DTC in
the instrument cluster come on.

For better control

If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.

If the indicator lamps are on:
DTC has been activated.

Deactivating DTC

Press the button again; the DTC indicator
lamps in the instrument cluster go 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.

Hold the car in place by depressing the
brake.

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 system does not measure the actual infla-
tion pressure in the tires.
The system detects a tire pressure loss due to
speed comparisons among the individual
wheels as you drive.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. The system detects this
and reports it as a flat tire.

Functional requirement

The system has to have been initialized at the
correct inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.

System limitations

It is impossible to provide advance warn-
ing of sudden, severe tire damage caused

by outside influences.

The system will not detect a natural, uniform
pressure loss in all four tires. Therefore you
should check the inflation pressure regularly.
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

Driving with snow chains

Initialization

In the initialization, the set inflation pressures
are adopted as reference values for the detec-
tion of a flat tire. The initialization is begun by
confirmation of the inflation pressures.
