Manual convertible top
The fabric top offers perfect protection
against the weather and it can be opened
easily and quickly by one person alone.
Here are a few tips so that you get the most
out of your BMW:
>It is advisable to close the convertible
top when the vehicle is parked.
The closed convertible top not only pro-
tects the passenger compartment from
unforeseeable damage from the
weather, but also provides a certain
degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even
with the convertible top closed
>When the convertible top is open, the
central locking system also locks the
release button for the convertible top.
The convertible top cannot be oper-
ated. This provides better theft protec-
tion for valuables stored in the luggage
compartment
>Never mount a roof-mounted luggage
rack system on the convertible top.
To open the convertible top
Operate the convertible top only
when the vehicle is stationary.
Never store the convertible top for longer
than one day while it is wet to avoid perma-
nent damage from moisture.<
Before opening the convertible top,
make sure that the convertible top
compartment panel in the luggage com-
partment is lowered to avoid any possible
damage; refer to page 20.<1.Flip the handle out and turn it to the end

vertible top to begin fluttering. Increase the
air supply so that low pressure does not
occur in the vehicle.<

Here are a few tips so that you get the most
out of your BMW:
>It is advisable to close the convertible
top when the vehicle is parked. When
closed, the top not only guards the pas-
senger compartment from unforesee-
able damage from the weather, but also
affords a degree of protection against
theft. In addition, only keep valuables in
the locked luggage compartment, even
with the convertible top closed
>Never mount a roof-mounted luggage
rack system on the convertible top.
>To prevent damage, do not operate the
convertible top at temperatures below
147/–106.Never store the convertible top while
it is wet to avoid permanent damage
from moisture.
Driving when the opening or closing pro-
cess has not been completed can cause
vehicle damage or personal injury.
Do not lay objects on the convertible top,
since they could fall off when the convert-
ible top is operated and cause damage or
injuries.
Do not reach into the convertible top mech-
anism during opening and closing. Keep
children away from the moving parts of the
convertible top during operation.<
If possible, only operate the convert-
ible top with the vehicle stopped, as
otherwise the process may be interrupted.
If you set the convertible top in motion
while the vehicle is stationary and then
have to start suddenly, for instance at a
traffic light, you can still complete the pro-
cedure by driving as slowly as possible and
again holding the corresponding button
pressed.<

compartment may develop relatively

If at all possible, only operate the con-
vertible top if the engine is running.
This saves unnecessary battery wear.
Before closing the convertible top, remove
any objects from the windshield frame that

Maintenance
The BMW Maintenance
System
The BMW Maintenance System has been
designed as a reliable means of providing
maximum driving and operating safety, and
as cost-effectively for you as possible.
Please keep in mind that regular mainte-
nance is not only necessary for the safety
of your vehicle, but also plays a significant
role in maintaining the resale value of your
vehicle.
Service interval display
While conventional systems rely on dis-
tance traveled alone to determine when a
service is due, the BMW Maintenance Sys-
tem has taken the actual conditions under
which the vehicle is operated into consid-
eration for years, because miles can be
traveled in many different ways:
From a maintenance point of view,
60,000 miles/100,000 km accumulated in
short-distance urban driving are not the
same as 60,000 miles/100,000 km accu-
mulated at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System includes
the Engine Oil Service and Inspections I
and II.
Determining the maintenance intervals
based on the actual loads on the vehicle
covers every kind of operating situation.
Minimal use drivers, who drive fewer than
about 6,200 miles/10,000 km per year,
should nevertheless have the oil changed at least every 2 years since engine oil dete-
riorates over time, regardless of use.

Service Guide Booklet for Canadian
models
For additional information on required
maintenance intervals and procedures,
please refer to the Service and Warranty
Information Booklet for US models, or the
Warranty and Service Guide Booklet for
Canadian models.
Depending on operating conditions, it may
be advisable to have the body checked for
damage from rocks or gravel as a precau-
tion against corrosion.
BMW recommends that you have your
BMW center perform the mainte-
nance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty Infor-
mation Booklet for US models, Warranty
and Service Guide Booklet for Canadian
models. These entries will serve as proof
that the vehicle has received regular main-
tenance.<
