Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat,
surface. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or reverse
(selector lever in Park with automatic
transmission) and engage the parking
brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and
regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, loose
gravel, etc.), as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. They could
prevent the jack from extending to its
full height and reduce its support
capacity.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack Ð risk of fatal injury.<
Your BMW is equipped with a spare tire
or a space-saver spare tire designed for
temporary use in maintaining the
vehicle's mobility in an emergency.
To remove the spare tire, lift the
floor panel in the cargo area
completely out, refer to page 99.<

Changing a wheel Battery Fuses
Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<
If the defective wheel cannot be seen
as such immediately from the outside,
check the tire inflation pressure at all
four wheels.
Have the tires changed by your
BMW center. For safety reasons,
do not have a safety tire repaired. Your
BMW center has the information
needed for working with safety tires
and is equipped with the necessary
special tools.<
If appropriate, please consult your
BMW center to reequip your
vehicle from summer to winter tires Ð or
vice versa.<
Battery careThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the battery
is absolutely maintenance-free, the
following is for your information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. vehicle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment.
Terminal locations, refer to Jump-
starting on page 134.
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for
transport and storage. Secure the
battery against tilting during transport.<
The fuses are located in the glove
compartment behind a cover secured
by two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<

134n
Do not use spray starter fluids to start
the engine.
When your battery is discharged you can
used two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. Ensure that the battery in the support
vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit
hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
(arrow 1). The cover on this auxiliary
terminal is identified by a "+" symbol.
Remove by pulling the tab
6. Next, connect one end of the other
jumper cable (Ð) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut on
your BMW (2)
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
7. Start the support vehicle's engine
and let it run at an increased idling
speed for a few minutes. Start the
engine on the vehicle needing the
jump-start, and allow it to run as
usual. If the first start attempt is not
successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge
8. Before disconnecting the jumper
cables let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery recharged by your
BMW center.
