BMW 3: Manual Speed Limiter

Concept

The system can be used to set a speed limit, for instance to prevent the vehicle from exceeding speed limits.

General information

The system can limit the speed, starting at a value of 20 mph/30 km/h. The vehicle can be driven at any speed below the set speed limit.

Overview

Buttons on the steering wheel

System on/off.

Store current speed.

Speed Limit Assist: take over suggested speed manually.

Rocker switch: Changing the speed limit.

Operation

Switching on

Press the button on the steering wheel.

The current speed is accepted as the speed limit.

If the system is switched on while the vehicle is stationary or driving at low speeds, 20 mph/30 km/h is set as the speed limit.

The marking in the speedometer is set to the respective speed.

When the speed limit is switched on, DSC Dynamic Stability Control and COMFORT driving mode may be switched on as well.

Switching off

Press the button on the steering wheel.

The system switches off automatically in the following situations, for example:

• When the engine is switched off.
• When cruise control is switched on.
• When certain programs are activated via the Driving Dynamics Control.

The displays go out.

Interrupting

If the reverse gear is engaged or at idle, the system is interrupted when rolling backwards.

Changing the speed limit

Press the rocker switch up or down repeatedly until the desired speed limit is set.

• Each time the rocker switch is pressed to the resistance point, the speed limit increases or decreases by 1 mph/1 km/h.
• Each time the rocker switch is pressed past the resistance point, the desired speed changes by a maximum of 5 mph/10 km/h.

If the set speed limit is reached or unintentionally exceeded, such as when driving downhill, the vehicle is not actively braked.

If the speed limit is set during a trip to a value below the current speed, the vehicle coasts until it drops to the set speed limit.

The current speed can also be stored by pressing a button:

Press the button on the steering wheel.

Exceeding the speed limit

If the vehicle speed exceeds the set speed limit, a warning is issued.

The speed limit can be exceeded intentionally.

There is no warning in this case.

Press the accelerator pedal all the way down to intentionally exceed the set speed limit.

When the vehicle speed drops below the set speed limit, the limit is automatically reactivated.

Warning when the speed limit is exceeded

Visual warning

If the speed limit is exceeded: the indicator light in the instrument cluster flashes while the vehicle speed is greater than the set speed limit.

Acoustic warning

• If the speed limit is exceeded unintentionally, a signal sounds.
• If the speed limit is reduced to below the vehicle speed while driving, the signal sounds after some time.
• If the speed limit is intentionally exceeded by stepping on the accelerator pedal all the way down, there is no signal.
