2. Pull off the plug  
3. Push the new bulb holder with the  
bulb into the plug – ensure proper  
locking  
4. Reinstall in reverse order.  
Do not touch the glass portion of  
a new bulb with your bare hands  
since even small amounts of impurities  
burn in to the surface and reduce the  
service life of the bulb. Use a clean  
cloth, paper napkin, or a similar mate-  
rial, or hold the bulb by its metallic  
base.<  
When cleaning the headlamps,  
please observe the following:  
> Do not wipe dry (this causes  
scratches) and never use abrasives  
or strong solvents to clean the covers  
> Remove dirt and contamination (such  
as insects) by soaking with BMW Car  
Shampoo and then rinsing with plenty  
of water

Before working on the electrical  
system, switch off the electrical  
accessory you are working on or  
disconnect the cable from the negative  
terminal of the battery. Failure to  
observe this precaution could result in  
short circuits.  
The bulb is pressurized. There-  
fore, wear safety glasses and  
protective gloves. Failure to comply  
with these precautions could result in  
physical injury if the bulb breaks.<

What you will need  
The illustration depicts an example of  
the onboard tool kit of the Z3 coupe.  
Other than the warning triangle, the  
same tools are arranged somewhat  
differently in the storage compartment  
of the Z3 roadster.  
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 safety guidelines and regula-  
tions.  
In order to avoid rattling noises later,  
note the position of the tools when you  
remove them and return them to their  
original position when you are through  
using them.  
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, tiles, loose  
gravel, etc.), since it could slide side-  
ways.

speed of 50 mph (80 km/h).  
Be aware that vehicle handling will be  
altered. Slower brake response time,  
longer braking distances and changed  
steering characteristics may be antici-  
pated when approaching limit condi-  
tions.  
Replace the defective tire as soon as  
possible and have the new wheel/tire  
balanced.  
14. Check and correct the inflation  
pressure at the earliest opportunity.  
Use only the full wheel cover  
installed by the factory. Other  
wheel covers may not fit securely. The  
full wheel cover may not be installed on  
the spare wheel because the cover  
could be damaged.<  
Only one spare wheel may be  
mounted at any time. Mount a  
wheel and tire with the same size and  
specifications as the others at the  
earliest possible opportunity. Maintain  
the specified tire inflation pressures,  
refer to the table on page 27.<  
The jack is designed for changing  
wheels only. Do not attempt to lift  
a different vehicle model or any other  
type of load with the jack. To do so  
could lead to property damage or  
personal injury.  
To ensure continued safety, check the  
tightness of the lug bolts at the earliest  
opportunity (torque specification:

154nBattery  
If you intend to store your vehicle for  
longer than twelve weeks: remove the  
battery, charge it and store it in a cool  
(but frost- and dust-free) room. Every  
three months and before reinstalling the  
battery, have it recharged. If it is not  
recharged, it will not be serviceable.  
Every time the battery is discharged,  
especially over extended periods, its  
service life is reduced, refer also to  
page 131.  
Charging the battery  
Charge the battery in the vehicle only  
when the engine is switched off.  
Charge the battery using the auxiliary  
jump-start terminal and a ground in the  
engine compartment, refer to Jump-  
starting on page 158.  
Before performing any work on  
the electrical system, disconnect  
the cable from the negative terminal. If  
you do not, short circuits can create the  
risk of fire or personal injury.<  
Return used batteries to a recy-  
cling point or your BMW center.  
Maintain the battery in an upright posi-  
tion for transport and storage. Secure  
the battery against tilting when trans-  
porting.<  
Charge condition  
You can read the charge condition of  
the battery with the "Magic Eye"  
(hydrometer):  
If you plan to park the vehicle for longer  
than 4 weeks, disconnect the battery  
from the vehicle electrical system by  
disconnecting the cable at the negative  
terminal. Then recharge the battery with  
an appropriate battery charger.  
> Green: adequate charge  
> Black: not charged adequately.  
The battery must be recharged  
Please contact your BMW center.  
> Yellow: replace the battery.  
The projected service life of the  
battery can only be reached if the  
battery is fully-charged at all times.  
Check the charge condition of the  
battery frequently if the vehicle is used  
primarily for driving short distances. <

Removal and installation  
Do not disconnect the battery  
cables when the engine is running.  
Disconnecting the battery cables when  
the engine is running will cause a  
voltage surge which will damage the  
vehicle's onboard electronics.  
Do not make any modifications in the  
wires leading to the positive terminal. If  
you do so, the battery safety terminal's  
safety function will no longer be guaran-  
teed. Repair and disposal must be  
performed by trained technicians only.<  
Z3 coupe  
Z3 coupe:  
Loosen the screw (arrow) on the battery  
safety bar and remove the bar.  
When removing the battery, disconnect  
the negative terminal first, then the  
positive terminal.  
When installing the battery, connect the  
positive terminal first, then connect the  
negative terminal.  
Unscrew the battery retaining clamp.  
When installing the battery, be  
sure that the battery and the  
safety bar (Z3 coupe) are mounted  
properly. If this is not done, the battery  
will not be adequately secured in case  
of an accident.<  
 
156nFuses  
A listing of the fuses, their respective  
ampere ratings and the equipment in  
their circuits is provided on the cover of  
the fuse box.  
When you close the fuse box, be sure  
that the cover is seated securely.  
Do not attempt to repair a burned  
fuse or replace it with a fuse  
having a different color or ampere  
rating. To do this could cause a fire in  
the vehicle resulting from a circuit over-  
load.<  
If an electrical accessory should fail,  
switch it off and check the fuse.  
If a fuse burns through again, have the  
source of the fault checked and  
corrected by a BMW center.  
The fuse box (electrical distribution  
center), which contains spare fuses,  
relays and plastic tweezers, is located  
on the left-hand side of the engine  
compartment, refer to page 120.  
1. Press the retaining flap in and lift off  
the cover  
2. Use the plastic tweezers to remove  
the fuse for the accessory or equip-  
ment that has stopped working  
3. If the fuse is burned through  
("blown"), the metal strip will have  
melted and separated. Replace the  
blown fuse with a new fuse of the  
same ampere rating (color code).

158nJump-starting  
Never 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 components  
carrying high-voltage on a running  
engine. Contact with components  
carrying high voltage can cause fatal  
injury. Carefully observe the following  
instructions to avoid personal injury  
and/or damage to one or both vehi-  
cles.<  
4. Start the engine on the support  
vehicle and allow it to run  
6. Then connect the negative terminals.  
Connect one end of the other jumper  
cable (–) to either the support  
5. Use the 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  
specifically for jump-starting. The  
cover on this auxiliary terminal is  
identified by a "+" symbol, refer to  
the illustration. Pull up to open the  
cover  
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 the  
strut dome of your BMW; refer to the  
arrow in the illustration  
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 the battery from  
your vehicle's electrical system.  
Switch off all electrical accessories in  
both vehicles  
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  
Tow fitting  
Rear:  
Use a screwdriver to press the cover  
out.  
9. Then disconnect the jumper cables  
in reverse sequence.  
The screw-in tow fitting is stored in the  
onboard tool kit; be sure that it remains  
in the vehicle at all times. This fitting  
is designed for installation in the tow  
sockets located at the front and rear of  
the vehicle, and is intended for towing  
on paved road surfaces only.  
Depending on the cause of the fault,  
have the battery recharged by your  
BMW center.  
Screw the tow fitting in until it is  
tight against the stop. If you do  
not, the threads can be damaged.  
Do not tow the vehicle by any compo-  
nents of the running gear, or lash them  
down in any way. If you do so, the  
components could be damaged,  
leading to possible accidents.<  
It should not be used to pull a vehicle  
out of deep snow, mud, sand, etc.  
Comply with all applicable towing laws  
and regulations at all times.  
Use only a nylon towing strap to tow  
the vehicle, since the inherent resil-  
ience of this material helps protect both  
vehicles from sudden jerking move-  
ments.  
Access to tow sockets  
Front:  
Use a screwdriver to press the cover

flashers (observe applicable legal  
regulations).  
> Do not tow with sling-type equipment  
> Use a wheel-lift or flatbed equipment  
> Comply with applicable towing laws.  
Find some means of identifying the  
vehicle in tow. Place a sign or warning  
triangle in the rear window, for  
instance.  
Never allow passengers to ride in  
a towed vehicle for any reason.  
Never attach tie-down hooks, chains,  
straps, or tow hooks to tie rods, control  
arms, or any other part of the vehicle  
suspension, as severe damage to these  
components will occur, leading to  
possible accidents.<  
Even when the electrical system  
has failed, make sure that the igni-  
tion key remains in position 1 to prevent  
the steering lock from engaging.  
The steering and brakes are without  
power assist when the engine is off.  
This means that increased effort is  
required for steering and braking.<
