direction, the transmission shifts up. When

the lever is tapped in the – direction, the

transmission shifts down. M1 to M5 appear

in the gear indicator.

The Adaptive Transmission Control ATC

executes upshifts or downshifts only when

the new gear will provide a suitable combi-

nation of engine and road speed, e.g. ATC

will not execute downshifts if the engine

speed is too high. The desired gear will

appear briefly in the instrument cluster, fol-

lowed by the actual gear.

If you are driving in the manual mode

and wish to accelerate rapidly, e.g. to

pass another vehicle, shift down manually

or with the kickdown function.<

Shifting from M/S to selector lever posi-

tions P, R and N is possible only by going

through position D.

Malfunction

If the indicator lamp comes on,

there is a malfunction in the trans-

mission system.

All of the selector lever positions can con-

tinue to be engaged; in the forward drive

positions, however, the vehicle will be

operating in the fourth gear only.

If this happens, avoid extreme engine loads

and consult the nearest BMW center.

Never work in the engine compart-

ment when a drive gear – forward or

reverse – is engaged. If you do so, the vehi-

cle could move.<

For jump-starting or towing, refer to the

information beginning on page 94.

Sequential manual gearbox

The concept

The sequential manual gearbox SMG is an

automated manual gearbox with which

The SMG is operated via two shift paddles

on the steering wheel and the selector lever

in the center console.

It offers the following functions:

> Sequential mode: manual mode

> Drive mode: automated mode

> Ability to choose between two different

driving programs: Standard, Sport,

refer to Dynamic Driving Control

> Operating safety through protection

against misshifting

> Automatic upshifts and downshifts in

the drive mode

> Automatic downshifts at minimum

engine rpm

> Kickdown function in the drive mode

> Acceleration assistant.
