Owner service procedures -> Giving and receiving assistance: Jump-starting, Towing for Your BMW Z8 Roadster First Generation (2000-2003)

Jump-starting  
145n  
Do not use spray starter fluids to start  
the engine.  
If the battery is discharged, the engine  
can be started with the use of two  
jumper cables and the battery of  
another vehicle. You can also use the  
same method to help start another  
vehicle. Use only jumper cables with  
fully insulated grips on the terminal  
clamps.  
Do not touch high-voltage wiring  
and cables on a running engine.  
5. Use one jumper cable (+) to connect 6. Next, connect one end of the other  
There is a risk of fatal injury if you do  
this. Carefully comply with the following  
instructions to avoid personal injury or  
damage to one or both vehicles.<  
the positive terminal of the battery in  
the support vehicle with the auxiliary  
positive terminal provided in the  
jumper cable (–) 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  
provided for this on the BMW (see  
illustration)  
engine compartment of your BMW  
specifically for jump-starting. The  
cover of the auxiliary terminal for use  
in jump-starting your BMW is identi-  
fied by a "+" symbol, refer to illustra-  
tion. Lift off by pulling the tab (arrow)  
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  
Follow the same sequence for  
connecting the jumper cables,  
otherwise, you run the risk of injury  
caused by spark generation at the  
battery.<  
3 Make absolutely certain that there is  
no contact between the bodywork of  
the two vehicles – short circuit hazard  
4 Start the engine on the support  
vehicle and allow it to run

7. Start the support vehicle's engine  
and let it run at an increased idling  
speed for a few minites. 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.  
Use a screwdriver to press sideways  
on the opening to remove the cover  
(arrow).  
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. It 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  
bottoms firmly. If this is not done,  
the threads could 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.  
Always observe all applicable towing  
laws and regulations.  
Access to tow sockets  
Use only a nylon towing strap to tow  
the vehicle. The inherent resilience of  
this material helps protect both vehicles  
from sudden jerking movements.  
Front:  
The uppermost grille stub is clipped on  
the grille – which is located below the  
main grille on the lower right – and this  
grille can be pulled off, if you pull  
forward on it.  
Towing the vehicle  
147n  
Avoid "off-center" towing. Be sure  
that the tow rope is pulled tightly  
when the towing vehicle begins to  
move.<  
Towing a vehicle  
1. Put the shift lever in neutral  
2. Towing speed:  
Max. 45 mph (70 km/h)  
3. Towing distance:  
Max. 95 miles (150 km)  
The towed vehicle should always  
be the lighter of the two vehicles.  
If this is not the case, it is no longer  
possible to control vehicle response.<  
4. Leave the ignition key in position 1 to  
ensure that the brake lamps, turn  
signals, horn and windshield wipers  
remain operative, and to prevent the  
steering lock detent from engaging  
5. Switch on the hazard warning system  
(comply with country-specific regula-  
tions).

vehicle in tow, e.g. place a sign or  
warning triangle in the rear window.  
Make sure that the ignition key  
remains in position 1 even when  
the electrical system has failed to  
prevent the steering lock from  
engaging. The steering and brakes are  
without power assist when the engine is  
not running. This means that increased  
effort is required for steering and  
braking.<  
Never allow passengers to ride in  
a towed vehicle for any reason.<
