Changing a wheel Safety tiresYour BMW Z8 roadster is equipped
with safety tires.
The safety tires are made of self-
supporting tires mounted on specially-
designed wheel rims. Special reinforce-
ment elements support the sidewalls in
the event of pressure loss. Although tire
performance is then restricted, the
vehicle can still be driven on the
deflated tire for a limited distance. Your
vehicle is equipped with a tire pressure
monitor that signals you in case of a flat
tire.
In the event of a flat tireThe red indicator lamp on the instru-
ment panel will flash in the event of a
flat tire. In addition, a gong will sound.
Refer to page 67.
Carefully reduce speed to less than
50 mph (80 km/h), avoiding any hard
braking or steering maneuvers while
doing so.
You will still be able to drive approx.
155 miles (250 km) on your safety tire,
until you can get to a safe place to park,
a gas station, or to your nearest BMW
center. Under minimum vehicle loading,
it could conceivably last more than
155 miles (250 km).
If you cannot immediately determine
which tire is defective just by looking
at it, then check the tire pressure in all
four tires.Have your BMW center replace
your tires. For safety reasons, do
not have safety tires repaired. Your
BMW center has been trained to work
with the safety tires and is equipped
with the necessary special tools.<
If necessary, please have your
BMW center switch the tires on
your vehicle from summer to winter
tires, or the reverse.<

Towing the vehicle
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
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.<
Tow-startingFor instructions on jump-starting, refer
to page 145.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1. Put the shift lever in neutral
2. Towing speed:
Max. 45 mph (70 km/h)
3. Towing distance:
Max. 95 miles (150 km)
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).
Find some means of identifying the
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.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use a wheel lift or flatbed equipment
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.<520us014

Dynamic Stability Control (DSC)

Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
When the system detects substantial
differences in rotation rates between
wheels, it acts to inhibit uncontrolled
wheelspin by reducing the drive torque
transmitted to the affected wheel(s),
while also initiating selective braking
intervention as needed.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal
status calculated based on sensor
signals. DSC reacts to deviations from
this ideal status, such as incipient
understeer or oversteer, to restore the
vehicle's stability using a combination
of adjustments to engine torque and
selective braking applications at indi-
vidual wheels. Dangerous skids are
thus prevented before they can even
start, all of this is possible, of course,
only within physically possible limits.You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to the
system.
