2009 BMW X6 XDRIVE 50I catalytic converter

Driving
66
The ignition switches off automatically
* if the
driver's door is opened. Pressing the start/stop
button again switches the ignition back on.
For example, the ignition is not switched off in
the following situations:
> the brakes are actuated
> the low beams are switched on
Starting engine
Do not run the engine in closed rooms,
otherwise the inhalati on of toxic exhaust
gases can cause uncons ciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattend ed vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
engage transmission position N or P and set the
parking brake before le aving the vehicle with
the engine running. <
Do not allow the engine to warm up by leaving it
running while the vehicl e remains stationary.
Instead, begin to drive at a moderate engine
speed.
The engine starts when you depress the
brake pedal while pressing the Start/Stop
button. <
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter. < Remote control in ignition lock or with comfort
access in vehicle, refer to page
39.
1. Depress brake pedal.
2. Press the Start/Stop button.
The system responds by automatically engag-
ing the starter for a cert ain period and automat-
ically disengaging it as soon as the engine
starts.
Diesel engine
When the engine is cold and outside tempera-
tures are below approx. 32 7/06 , the starting
process may be briefly delayed by an automatic
preglow phase. The pr eglow indicator lamp
lights up in the instrument panel and a message
appears on the Control Display.
Switching off engine
When leaving the vehicle, always take
along the remote control.
Set the parking brake firmly when parking; oth-
erwise, the vehicle could roll. <
Procedure
1.Engage transmission position P with the
vehicle stationary.
2. Press the Start/Stop button.
3. Set the parking brake.
4. Remove the remote control from the igni-
tion lock, refer to page 65.
Before driving into a car wash
The vehicle can roll if yo u proceed according to
the following steps:
1. With comfort access
*: insert the remote
control into the ignition lock.
2. Depress brake pedal.
3. Engage transmission position N.
4. Release the parking brake or deactivate
Automatic Hold.
5. Switch off the engine.

Fuel specifications
Gasoline engine: required fuel
Do not use leaded gasoline, otherwise
damage to the catalytic converter will
result.
Do not use E85, i.e. fuel that consists of 85 %
ethanol, or Flex Fuel, otherwise permanent
damage to the engine and the fuel supply sys-
tem will result. <
Super Premium Gasoline/AKI 91
This gasoline is hi ghly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is 87.
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 affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result. <
Use high-quality brands
Field experience has in dicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among ga solines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranti es with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certai n 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
you are using, we recommend that you respond
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 un scheduled maintenance. <
BMW X5 with BMW Advanced Diesel:
Required fuel
Ultra-low sulfur diesel
The engine of your BMW is designed for diesel
with a low sulfur content:
Ultra-low sulfur diesel ASTM D 975-07a.
Refuel only with ultra-low sulfur diesel.
The percentage of biodiesel in the fuel
must not exceed 5 Ξ, referred to as B5. Do not
refuel with gasoline. If the vehicle has been
refueled with incorrect fuel such as gasoline, do
not start the engine; otherwise, there is a dan-
ger of engine damage. <
After incorrect refueling, contact a BMW Sports
Activity Vehicle Center.
The fuel filling neck is designed for refuel-
ing with diesel nozzles.
If the nozzle cannot be inserted into the fuel
filler pipe of your BMW, please check to make
sure that you are refueling with a diesel fuel
pump and whether this is equipped with a diesel
nozzle. <
Winter diesel
In order to assure the operational reliability of
the diesel engine, during cold seasons, please
refuel with winter diesel, which is sold at fuel
stations during this time of year. The standard
fuel filter heating prevents the supply of fuel
from stalling during driving.
Do not mix in any additives or gasoline;
otherwise, there is the risk of engine dam-
age. <
BMW X5 with BMW Advanced
Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxides
in the diesel exhaust of your vehicle by injecting
the reducing agent diesel exhaust fluid into the
exhaust line. In the cata lytic converter, a chem-
ical reaction occurs th at minimizes nitrogen
oxides.

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument cluster
under a cover.
Exhaust-gas values
The warning lamp lights up:
The vehicle is producing an elevated
amount of exhaust emissions. Contin-
ued driving is possible. Have it checked at your
BMW Sports Activity Vehicle Center as soon as
possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under ce rtain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce your speed and
proceed to the nearest BMW Sports Activity
Vehicle Center. Heavy engine misfiring causes
serious damage to the emission-relevant com-
ponents, especially th e catalytic converter,
within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days. <
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
v e hi c l e d a t a o r i n f o r m a t i o n . I f y o u h a v e a l s o s u b -
scribed to BMW Assist, ce rtain vehicle data can
be transmitted or reco rded to enable corre-
sponding services.
