2015 BMW Z4 catalytic converter

Radio ready stateIndividual electrical consumers can operate.
The time and the external temperature are dis‐
played in the instrument cluster.
Radio ready state is switched off automatically:▷When the remote control is removed from
the ignition lock.▷In cars with Comfort Access, by touching
the surface above the door lock, locking,
refer to page 40.
Ignition on
All electrical consumers can operate. The od‐
ometer and trip odometer are displayed in the
instrument cluster.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Radio ready state and ignition off
All indicator and warning lamps as well as dis‐
plays in the instrument cluster go out.
Sport automatic transmission
In certain situations, transmission position P is
engaged automatically. To make it possible for
the vehicle to roll, such as in an automatic car
wash, follow the instructions in Car washes, re‐
fer to page 257.
Starting the engine Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Unattended vehicle
Do not leave the car unattended with the
engine running; otherwise, it presents a poten‐
tial source of danger.
Before leaving the car with the engine running,
set the parking brake and place the transmis‐
sion in position P or neutral to prevent the car
from moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page 39.
1.Depress the brake pedal.2.Depress the clutch pedal.3.Press the Start/Stop button.

Fuel recommendationVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Gasoline For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Do not use fuels that are labeled at the fuel
pump as containing metals.
Only refuel with lead-free gasoline with‐
out metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀
Fuels with a maximum ethanol content of
10 %, i.e., E10, may be used for refueling.
The ethanol should fulfill the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: always adhere to the currently applicable
standard.
Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as
this would damage the engine and fuel supply
system.◀The engine is knock controlled. Therefore, you
can refuel with different recommended fuel
grades.
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not fill up with fuel below the speci‐
fied minimum quality; otherwise, the engine
may not run properly.◀
If you use gasoline with this minimum AKI rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Minimum fuel grade
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to
purchase gasoline from BP or Top Tier retail‐
ers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀Seite 226MobilityFuel recommendation226

Booklet for US models, and in the Warranty
and Service Guide Booklet for Canadian mod‐
els. These entries are proof of regular mainte‐
nance.
Socket for OBD Onboard
Diagnosis
Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions.◀
On the driver's side is an OBD socket for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning light lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.▷The warning light flashes under certain cir‐
cumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐riod can seriously damage emission con‐
trol components, in particular the catalytic
converter.
Display of the previously described
malfunctions on Canadian models.
Fuel cap The indicator lamp lights up.
If the fuel cap is not properly tight‐
ened, the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
