warning light BMW Z4 SDRIVE35I ROADSTER 2010 User Guide

Technology for driving comfort and safety
86 vidual components of the system or its wiring in
any way. This includes the upholstered covers
of the steering wheel, the dashboard and the
seats. Do not attempt to remove or dismantle
the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the passenger
seat is occupied by measuring the resistance of
the human body. Front, knee and side airbags
on the passenger side are activated or deacti-
vated accordingly.
Make sure that the passenger keeps his
or her feet in the footwell; otherwise, the
passenger airbags may not function properly.<
The indicator lamp above the interior rearview
mirror shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, see page48.
Malfunction of the automatic
deactivation system
The front, knee and side airbags can also be
deactivated by adolescents and adults sitting in
certain positions; the indicator lamp for the pas-
senger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, do not transport
the passenger in the vehicle.
To make sure that occupation of the seat cush-
ion can be detected correctly:
>Do not attach seat covers, seat cushion
padding, ball mats or other items to the pas-
senger seat unless they are specifically rec-
ommended by BMW.
>Do not place any items under the seat which
could press against the seat from below.<
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
>The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is
detected on the seat or the seat is empty.
The front, knee and side airbags for the pas-
senger are not activated.

Most child seats are detected by the sys-
tem, especially child seats required by the
NHTSA at the time of vehicle production.
After mounting a child seat, ensure that the
indicator lamp for the passenger airbag is lit.
It indicates that the child seat has been
detected and that the passenger airbags
are deactivated.
>The indicator lamp does not come on when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat.
The front, knee and passenger airbags for
the passenger are activated.
Operational readiness of airbag system
As of radio readiness, refer to page50, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
>Warning lamp does not light up at radio
readiness or beyond.
>Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a sufficiently severe acci-
dent occurs.<

Under the hood
204 >"Measurement inactive. Have this
checked."
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to page69. Have the system checked as
soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until
a corresponding message is shown on the
Control Display.
Add oil within the next 125 miles/200 km;
otherwise, the engine damage could
occur.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil types
Do not use oil additives as these may
cause engine damage.<
Specified engine oils
Your service center can advise you on which
engine oils have been approved by the manu-
facturer of your vehicle.
The engine oil quality is critical for the life of the
engine.Approved oils can be identified by the following
specification:
Approved oils belong to the following viscosity
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is
important to follow the instructions on the con-
tainers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the expansion tank cap counterclock-
wise slightly to allow any accumulated pres-
sure to escape, then continue turning
to open.
Preferred: BMW Longlife-01

Socket for Onboard
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located under a cover on the left
on the driver's side.
Exhaust emission values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car
checked as soon as possible.
Canadian models display this warn-
ing lamp.
The lamp flashes under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, especially the catalytic
converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas cap is then tightened, the
warning lamp should go out within a few days.
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a service contract for BMW Assist, cer-
tain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.
