Drive defensively

Avoid unnecessary acceleration and braking

maneuvers. To do so, keep an adequate dis-

tance to the forward vehicle. A defensive and

smooth driving style keeps fuel consumption

down.

Avoid high engine speeds

Only use first gear when setting off. In second

and higher gears, accelerate without hesitation

or pauses. When accelerating, shift up before

reaching high engine speeds.

When you reach the desired speed, shift into

the highest applicable gear and drive with the

engine speed as low as possible and at a con-

stant speed.

As a rule: driving at low engine speeds lowers

fuel consumption and reduces wear.

Coasting

When approaching a red light, take your foot off

the accelerator and coast to a stop in the high-

est applicable gear.

On a downhill slope, take your foot off the accel-

erator and coast in a suitable gear.

The fuel supply is interrupted when coasting.

Switch off the engine during lengthy

stops

Switch off the engine when stopping for lengthy

periods, e.g. at traffic lights, railroad crossings

or in traffic congestions. You achieve fuel sav-

ings even if standing time is as short as approx.

4 seconds.

Switch off functions you do not need at

the moment

Functions such as the air conditioner and the

seat or rear window heating draw large amounts

of power and consume additional fuel. Espe-

cially in city traffic and in stop and go driving

they have a considerable impact. Therefore,

switch these functions off when they are not

really needed.

Have the vehicle serviced

Have the vehicle serviced regularly to achieve

good economy and a long vehicle life. BMW

recommends having the vehicle serviced at a

BMW center. Also note the BMW service sys-

tem, refer to page 96.

Driving notes

Close the luggage compartment lid/

tailgate

Operate the vehicle only when the lug-

gage compartment lid/tailgate is closed.

Otherwise, exhaust fumes could enter the inte-

rior of the vehicle.<

Should it be absolutely necessary drive with the

luggage compartment lid/tailgate open:

1. Coupe: close both windows.

Roadster: close all windows if the convert-

ible top is closed.

2. Greatly increase the air flow from the air

conditioning or automatic climate control,

refer to page 62 or 65.

Hot exhaust system

In all vehicles, extremely high tempera-

tures are generated in the exhaust sys-

tem. Never remove the heat shields installed in

this area, nor apply undercoating to their sur-

faces. When driving, standing at idle or parking

the vehicle, take care to avoid contact between

the hot exhaust system and flammable materi-

als, e.g. hay, leaves, grass, etc. Such contact

could lead to a fire, resulting in serious personal

injury and property damage. Do not touch the

hot exhaust pipes to avoid the risk of injury from

burns.<

Hydroplaning

When driving on wet or slushy roads,

reduce vehicle speed. If you do not, a

wedge of water may form between the tires and

the road surface. This situation, known as

hydroplaning, means that the tire can com-
