Driving notes
Parking the vehicle
Condensation forms in the air conditioner
system during operation, which then exits
under the vehicle. Traces of condensed
water on the ground underneath the vehi-
cle are thus normal.
Brakes
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Hydroplaning
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the tires
and the road surface. This phenomenon
can lead to partial or complete loss of trac-
tion, vehicle control and braking effective-
ness.<
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft / 30 cm,
and then only at walking speed. Otherwise,
the vehicle's engine, the electrical systems
and the transmission may be damaged.<
High temperatures
High temperatures occur with every
vehicle equipped with a catalytic con-
verter. Heat shields are installed adjacent to
some sections of the exhaust system. Never
remove these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle and parking the vehicle,
take care to avoid contact between the hot
exhaust system and flammable materials –
e.g. hay, leaves, grass, etc. Such contact
could lead to a fire, resulting in serious per-
sonal injury and property damage.<
Brake system
The brake warning lamp lights up
although the parking brake is not
engaged: check the brake fluid
level. It is very important that you follow the
instructions on page 81 before driving on.
Disc brakes
Corrosion
Limited vehicle use, extended periods with
the vehicle parked or in storage, and oper-
ating conditions in which braking is
restricted to gentle, low-pressure applica-
tions will all increase the tendency for cor-
rosion to form on the rotors and contamina-
tion to accumulate on the brake pads. This
occurs because the minimal pressure
which must be exerted by the pads to clean
the rotors by brake applications is not
reached.
If the brake rotors are corroded, they will
tend to respond to braking with a pulsating
effect which even extended application will
fail to cure.
Wet roads
When driving in heavy rain and on wet
roads, it is useful to apply light pressure
to the brake pedal every few miles. Watch
traffic conditions to ensure that this maneu-
ver does not endanger other road users.
The heat generated in this process helps
dry the pads and rotors to ensure that your
brake system will respond with undimin-
ished efficiency when you need it.
Inclines
Extended or steep mountain descents
should be driven in the gear or drive posi-
tion in which only minimal periodic brake
application is required. This helps avoid
placing excessive loads on the brake sys-
tem. Observe the maximum allowable
engine speed when doing so; refer to
page 47.
Do not coast with the clutch
depressed or with the transmission or
selector lever in Neutral. Do not coast with

Special operating instructions
66 the engine switched off. Otherwise the
engine provides no braking effect and there
is no power-assist for braking or steering
when the engine is off.<
Brake pads
The yellow indicator lamp for the
brake pads lights up:
Have the condition of the brake
pads inspected.<
For your own safety: use brake pads
which the manufacturer has approved
for your specific vehicle model. The manu-
facturer cannot evaluate non-approved
brake pads to determine if they are suitable
for use, and therefore cannot ensure the
operating safety of the vehicle in the event
of their use.<
Cargo loading
Stowing cargo
>Load heavy cargo as far forward as
possible – directly behind the luggage
compartment partition – and as low as
possible
>Cover sharp edges and corners.
With the convertible top closed, you
can increase the space in your lug-
gage compartment. Refer to page 22.
We recommend that you always fold the
convertible top compartment panel down
as soon as you have removed your cargo
from the luggage compartment. This way,
you can be sure that you can always oper-
ate the convertible top at any time.
Conversely, when the convertible top is
closed, raise the convertible top compart-ment panel before stowing your cargo in
the luggage compartment to avoid any
damage to the convertible top compart-
ment or your load.<
If you stow cargo behind the seats of your
BMW Z4 roadster:
>Only stow light objects such as cloth-
ing, etc.
>Do not pile objects higher than the top
edge of the backrests.
To avoid damaging the rear of the
backrest or the rear interior trim
panel, do not stow heavy cargo or cargo
with sharp edges and corners behind the
seats.
In addition, large and bulky cargo stowed
behind the seats may prevent the backrest
from engaging properly. Ensure that the
backrest is securely locked by moving the
seat forward if necessary. Refer to
page 29.<
Always position and secure the load
correctly. If you do not, it can endan-
ger the passengers during braking or eva-
sive maneuvers.
Do not exceed the approved gross vehicle
weight or the specified maximum axle
loads. Refer to page 94. Otherwise the
vehicle's operating safety is no longer
assured and you are in violation of the law.
Do not stow heavy or hard objects in the
passenger compartment without first
securing them. Otherwise they would be
thrown around during braking and evasive
maneuvers and would endanger the occu-
pants.<

Run Flat tires
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC.
Run Flat tires consist of self-supporting
tires and special rims. The tire reinforce-
ment ensures that the tire retains some
residual safety in the event of pressure
drop and driving remains possible to a
restricted degree.
Because the sides of the Run Flat
tires are reinforced, a drop in inflation
pressure usually cannot be detected from
the outside.<
Flat tire
The red warning lamp in the instru-
ment cluster lights up when a tire
has failed. In addition, an acoustic
signal is heard. Refer to pages 14, 53.
1.Reduce vehicle speed carefully to
under 50 mph / 80 km/h. Avoid hard
brake applications and steering maneu-
vers
2.Do not exceed 50 mph / 80 km/h again
3.Find out which tire has been damaged;
to do so, check the tire inflation pres-
sure of all four tires at the earliest
opportunity. Refer to page 71
4.Correct the tire inflation pressure if you
wish to continue driving and if it is safe
to do so. Refer to the following section
5.Have the damaged tires changed by
your BMW center.
BMW recommends that you consult
your BMW center if you wish to replace the tires of your BMW, or change
from summer to winter tires or vice versa.
Your BMW center knows how to work with
Run Flat tires and is equipped with the nec-
essary special tools.<
For safety reasons, do not have Run
Flat tires repaired.
When replacing tires or changing from
summer to winter tires – or vice versa – use
Run Flat tires only since a spare tire will not
be available in the event of a flat tire.<
Driving with a damaged tire
When using Run Flat tires, you can con-
tinue driving cautiously at a maximum
speed of 50 mph / 80 km/h, depending on
the cargo load and the extent of tire dam-
age.
You can estimate the distance you can
continue driving on the basis of the follow-
ing values:
>Tire inflation pressure of 0 psi / 0 kPa:
approx. 100 miles / 150 km
>Tire inflation pressure of 7 – 15 psi
50 – 100 kPa:
approx. 300 miles / 500 km
>Tire inflation pressure greater than
15 psi / 100 kPa:
approx. 600 miles / 1,000 km.
Drive cautiously and do not exceed a
speed of 50 mph / 80 km/h. In the
event of pressure loss, changes in handling
characteristics – such as reduced stability
when braking, increased stopping dis-
tance, and altered steering response – may
occur.<

Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system:
approx. 3.2 US quarts / 3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 US quarts /
5 liters.
Fill with water and – if required – with an
antifreeze agent according to the manufac-
turer's recommendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. For this reason,
keep it away from sources of flame and
store it only in its original container. Store it
so that it is inaccessible to children. Com-
ply with the instructions on the contain-
ers.<
Engine oil
Engine oil pressure
The red engine oil warning lamp
lights up:
Stop the vehicle immediately and
switch off the engine. Check the engine oil
level and top off as required. If the oil level
is correct, please contact the nearest BMW
center.
Do not continue driving, as the engine
could sustain serious damage from
inadequate lubrication.<
Engine oil level
The yellow engine oil indicator lamp
lights up while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not
drive more than approx. 30 miles / 50 km
until you do.
The yellow engine oil indicator lamp
lights up after the engine is
switched off: add engine oil at the
earliest opportunity, when you stop to
refuel.
Engine oil sensor
The yellow engine oil indicator lamp
lights up within 20 seconds after
the engine is started:
The oil level sensor is defective. Please
have it checked by a BMW center.
Checking the oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil level should be between the two
marks on the dipstick
6.Return the dipstick to the guide tube,
inserting it as far as it will go.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.

In the engine compartment
80 The oil volume between the two marks on
the dipstick corresponds to approx.
1.1 US quarts / 1 liter. Do not fill beyond
the upper mark on the dipstick. Excess oil
will damage the engine.
Adding engine oil
While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.
BMW engines are designed to oper-
ate without oil additives; the use of
additives could even lead to damage in
some cases. This also applies to manual
and automatic transmissions and to the dif-
ferential.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For
this reason, thoroughly wash any areas of
skin that come into contact with oil using
soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and the
information on the containers.<
Comply with the applicable environ-
mental laws regulating the disposal of
used oil.<
Approved engine oils
The quality of the engine oil is extremely
important for the function and life of an
engine. Based on extensive testing, BMW
has approved certain grades of engine oil.
Use approved "BMW High Performance
Synthetic Oil".
If you are unable to obtain an approved
BMW High Performance Synthetic Oil, you may use small volumes of other synthetic
oils for topping up between oil changes.
Use only oils with the specification API SH
or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils that
have been approved.<

Coolant
The yellow coolant indicator lamp
lights up:
The coolant level is too low: top up
as soon as possible.
Do not add coolant to the cooling sys-
tem when the engine is hot. If you do,
escaping coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location inaccessible to children.
Antifreeze and anti-corrosion agents are
flammable. For this reason, do not spill
them on hot engine parts. They could ignite
and cause burns. Comply with the instruc-
tions on the containers.<
Checking the coolant level
Correct coolant level when the engine is
cold – at approx. 687 / 206:
1.Open the cap of the expansion tank by
turning it slightly counterclockwise to

allow accumulated pressure to escape,
then open completely
2.The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck but no more than ι in / 2 cm
above it, that is, up to the second mark
on the float. Refer also to the schematic
diagram next to the filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is reached
– do not overfill.
Comply with the applicable environ-
mental laws regulating the disposal of
extended-duty antifreeze with corrosion
inhibitor.<
Brake fluid
Indicator lamp
The brake warning lamp lights up
red when the parking brake is not
engaged: the brake fluid level is too
low, refer to page 65.
Brake warning lamp for Canadian
models
Brake fluid, refilling
Brake fluid loss may result in extended
brake pedal travel. If this occurs, also refer
to the notes on page 65.
Brake fluid is hygroscopic, that is, it
absorbs moisture from the air over
time.
In order to ensure the brake system's
safety and reliability, have the brake fluid changed every two years by a BMW center.
Refer also to page 48 and the Service Man-
ual.
Brake fluid is toxic and damages the vehi-
cle's paint. You should always store it in the
closed original container and in a location
inaccessible to children.
Do not spill the fluid and do not fill the brake
fluid reservoir beyond the MAX mark. The
brake fluid could ignite upon contact with
hot engine parts and cause serious
burns.<
Comply with the applicable environ-
mental laws regulating the disposal of
brake fluid.<
Brake fluid level
Low brake fluid level in the reservoir com-
bined with extended pedal travel may indi-
cate a defect in one of the brake system's
hydraulic circuits.
BMW recommends that you proceed
to the nearest BMW center. Higher
brake application pressure may be neces-
sary under these conditions, and braking
distances may be significantly longer.
Please remember to adapt your driving
style accordingly.<

Replacement procedures
88 Please consult your BMW center
whenever you have any questions
concerning the battery. Since the battery is
absolutely maintenance-free, the following
statements are for your information only.<
Do not disconnect the battery cables
when the engine is running. Discon-
necting the battery cables when the engine
is running will cause a voltage surge which
will damage the vehicle's onboard elec-
tronics.<
Indicator lamp
The indicator lamp for the battery
charge current lights up:
The battery is no longer being
charged. The alternator drive belt is defec-
tive or there is a malfunction in the charging
circuit of the alternator. Please contact the
nearest BMW center.
If the drive belt is defective, pull over
and switch off the engine immediately
to prevent overheating and serious engine
damage.
If the onboard supply voltage drops to a
very low level, increased steering effort
may also be necessary.<
Charging the battery
Charge the battery in the vehicle only when
the engine is not running. Use the terminals
provided in the engine compartment. For
information on connections, refer to Jump-
Starting on page 89.
Battery disposal
Return used batteries to a recycling
point or to your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Secure the battery
against tilting when transporting.<
Fuses
You will find the fuses and information on
their respective allocation behind the glove
compartment.
1.Press the lock on the left; see arrow 1
2.Press the lock on the right; see arrow 2
3.Swing the glove compartment down.
Spare fuses and plastic tweezers for grasp-
ing the fuses are found in the onboard tool
kit; refer to page 84.
Do not attempt to repair a burned fuse
or replace it with a fuse having a dif-
ferent color or amperage rating. To do this
could cause a fire in the vehicle as a result
of circuit overload.<
