2011 BMW 3 WAGON catalytic converter

Driving

Radio readiness and ignition off
All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard.
Before leaving the vehicle with the engine run-
ning, always shift into neutral or selector
position P and apply the parking brake force-
fully to prevent the vehicle from rolling.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a 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
page34.
1.Depress the brake.
2.Depress the clutch and shift to neutral posi-
tion.
3.Press the start/stop button.The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page34.
1.Depress the brake.
2.Move the selector lever to position P.
3.Press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Diesel engine
When the engine is cold and temperatures are
below approx. 327/06, the starting process
may take a little more time due to automatic
preheating. The preheating indicator lamp in
the instrument cluster comes on; at the same
time a message appears on the Control Display.
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking, apply the parking brake force-
fully; otherwise, the vehicle could begin to roll.<
Manual transmission
1.With the car at a standstill, press the start/
stop button.
2.Shift into first gear or reverse.
3.Forcefully apply the parking brake.
4.Removing the remote control from the igni-
tion lock, refer to page55.

Observe the following when refueling
When handling fuels, follow the safety
instructions provided at filling stations;
otherwise, there is a risk of personal injury or
property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to
>Premature pump shutoff
>Reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Gasoline engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Diesel engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 1.7 US gallons/6.5 liters.
Fuel specifications
Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>323i, 328i/xDrive: 87
>335i/xDrive: 89.
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.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
y o u a r e u s i n g , w e r e c o m m e n d t h a t y o u r e s p o n d
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Refueling

BMW Advanced Diesel: required fuel
Ultra-low sulfur diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-low sulfur diesel ASTM D 975-07a.
Refuel with ultra-low sulfur diesel only.
The percentage of biodiesel in the fuel
m u s t n o t e x c e e d 5 % ; t h i s t y p e o f f u e l i s r e f e r r e d
to as B5. Do not refuel with gasoline. If you have
accidentally refueled with the wrong fuel, e.g.
with gasoline, do not start the engine; other-
wise, engine damage may occur.<
If you have refueled with the wrong fuel, contact
your BMW center.
The filler neck is designed for refueling at
diesel fuel pumps.
If the filler nozzle cannot be inserted into your
BMW's filler pipe, please ensure that you are
refueling at a diesel fuel pump and that it is
equipped with a diesel filler nozzle.<
In the event the Ultra-Low Sulfur Diesel
fuel cannot be fully inserted into the fuel
filler neck, please contact BMW Roadside
Assistance for instructions on how to add fuel.
For more information on BMW Roadside Assis-
tance, refer to page246.<
Winter diesel
To ensure that the diesel engine remains oper-
ational in the winter, please use winter diesel,
which is available at gas stations during winter
months. The fuel filter heating system, included
as a standard feature, prevents disruption of the
fuel supply while driving.
Do not add additives, including gasoline;
otherwise, engine damage may occur.<
BMW Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxide
in the diesel emissions of your vehicle by means
of a mechanism that injects diesel exhaust fluid,
a reduction agent, into the exhaust tract.
A chemical reaction occurs in the catalytic
converter that minimizes the nitrogen oxide
content.
To be able to start the engine as usual, a suffi-
cient amount of diesel exhaust fluid must be
present in a separate reservoir.
Warming the system
To warm the system to its operating tempera-
ture after starting with a cold engine, the auto-
matic transmission delays shifting to the next
higher gear, if necessary.
Reserve display
A display in the instrument cluster informs you
about the remaining distance you can drive with
the fluid remaining in the reservoir.
The reserve display appears beginning at
approx. 1,000 miles/1,600 km before the sup-
ply is used up.
When this reserve display appears in the
instrument cluster, have diesel exhaust
fluid refilled to avoid not being able to start the
engine.<

Socket for Onboard
Diagnosis OBD
On the driver's side is an OBD socket for check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under certain conditions. 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. Make sure that the gas cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extract form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
