Electric Power Steering
EPS
The concept
The electric power steering is a direct,
sporting steering system that is speed-sen-
sitive.
Power support is reduced with an increase
in driving speed.
Indicator lamp

The system has malfunctioned or is
faulty.
Please have the system inspected by the
nearest BMW center.
Steering remains operational.

Beverage holder
A beverage holder is located on either side
beneath the air outlets.
1.Press the trim piece beneath the air
outlets; see arrow 1
2.Place the beverage into the holder
3.Adjust the holder to fit the size of the
beverage container; see arrow 2.
Do not place glass containers into the
beverage holders, as this increases
the risk of injury in the event of an acci-
dent.<
Preparations for the cellular
phone*
Hands-free system
In vehicles with telephone preparation, the
cover for the hands-free microphone is
located on the trim of the steering column.
For further information on the cellular
phone, refer to the Owner's Manual for the
telephone.
Ashtray*
To empty
1.Open cover
2.Pull out ashtray 1.
Cigarette lighter
Press in lighter 2. As soon as the lighter
springs back out, it can be removed.
Hold or touch the hot cigarette lighter
by the knob only. Holding or touching
it in other areas could result in burns.
The cigarette lighter remains operational
even when the ignition key has been
removed. For this reason, children should
never be left in the vehicle unattended.<
Cigarette lighter socket
This can be used for attaching power sup-
plies for flashlights, car vacuum cleaners
and other similar appliances up to a rating
of approx. 200 watts at 12 volts.
Do not damage the socket by insert-
ing plugs of a different shape or
size.<

Special operating instructions
70 Do not coast with the clutch
depressed or with the transmission or
selector lever in Neutral. Do not coast with
the engine switched off. Otherwise the
engine provides no braking effect and there
is no power-assist for braking or steering
when the engine is off.<
Brake pads
The yellow indicator lamp for the
brake pads lights up:
Have the condition of the brake
pads inspected.
For your own safety: use brake pads
which the manufacturer has approved
for your specific vehicle model. The manu-
facturer cannot evaluate non-approved
brake pads to determine if they are suitable
for use, and therefore cannot ensure the
operating safety of the vehicle in the event
of their use.<
Cargo loading
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Otherwise, overheating and
inner damage to the tires may result. The
ultimate result can assume the form of a
sudden air loss.<
Determining the maximum load
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occu-
pants and cargo should never
exceed XXX kg or YYY lbs; otherwise
damage to the vehicle and unstable
driving conditions could result.<2.Determine the combined weight of the
driver and passenger that will be riding
in your vehicle
3.Substract the combined weight of the
driver and passenger from XXX kilo-
grams or YYY pounds
4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
551 lbs. and there will be two 150 lbs.
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 251 lbs.
551 lbs. minus 300 lbs. = 251 lbs.
5.Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
Load
The permissible load is the sum of the
occupants' weights and the weight of the
cargo. The greater the weight of the occu-
pants, the less cargo can be transported.
Stowing cargo
>Load heavy cargo as far forward as
possible, directly behind the luggage
compartment partition, and as low as
possible
>Cover sharp edges and corners.
To avoid damaging the rear of the
backrest or the rear interior trim
panel, do not stow heavy cargo or cargo
with sharp edges and corners behind the
seats.
In addition, large and bulky cargo stowed
