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 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, 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 leaving the vehicle with
the engine running.<
Do not allow the engine to warm up by leaving it
running while the vehicle 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 not start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter. Access in vehicle, refer to page35.
1.Depress brake pedal.
2.Press the Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
Diesel engine
When the engine is cold and at temperatures
below approx. 327/06 the starting process
may be somewhat delayed due to automatic
preglowing. The preglowing indicator lamp in
the instrument panel lights up. 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 page58.
Before driving into a car wash
The vehicle can roll if you proceed according to
the following steps:

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 highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>BMW X5: 87
>BMW X6: 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 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 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 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 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
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 unscheduled 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.
Only refuel with ultra-low sulfur diesel.
The percentage of biodiesel in the fuel
must not exceed 5Ξ, 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.<
In the event the ultra-low sulfur diesel
nozzle 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 page274.<
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 filling
stations during this time of year. The standard
fuel filter heating prevents the supply of fuel
from stalling during driving.

Refueling
236 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 catalytic converter, a chem-
ical reaction occurs that minimizes nitrogen
oxides.
In order to be able to start the engine in the
usual way, there must be a sufficient supply of
diesel exhaust fluid in the separate reservoir.
System heating
In order to bring the system to operating tem-
perature after a cold start of the engine, the
automatic transmission shifts into the next
higher gear at a later point.
Reserve display
A display in the instrument panel informs you
about the remaining distance can be covered
with the amount of fuel currently in the tank.
The reserve display appears approx.
1,000 miles/1,600 km before the end of the
tank.
As soon as the reserve display has
appeared in the instrument panel, have
the diesel exhaust fluid refilled to prevent the
engine from being unable to restart.<
Diesel exhaust fluid at minimum
Even with a display of -- mls, the engine will
continue to run, provided that it is not switched
off, and all other operating requirements are
met, e.g. sufficient fuel.
Do not drive until the displayed remaining
distance runs out. Otherwise, it may not
be possible to restart the engine.<
Incorrect fueling
The warning lamp lights up:
The reservoir has been filled with an
incorrect fluid.
Please contact your BMW Sports Activity Vehi-
cle Center.

Socket for OBD Onboard
Diagnostics interface
The chief components that make up the emis-
sions content can be checked by a device that
uses the OBD socket.
This socket is located to the left on the driver's
side, on the underside of the instrument cluster
under a cover.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. Continued driving is possible.
Have the vehicle checked as soon as possible.
The lamp flashes under certain 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 the catalytic converter,
within a short time.
The warning lamp lights up if the fuel
cap has not been properly tightened
and the OBD system detects the
escape of fuel vapors. Check that the fuel cap is
correctly seated and tighten it until you hear a
clearly audible click.
Data memory
Your vehicle records data on vehicle operation,
malfunctions and user settings. These data are
stored in the vehicle and in part in the remote
control and can be read out by suitable devices
during service, for example. The read data are
used to assist in servicing and repairing your
vehicle or for the optimization and continued development of vehicle functions. In addition, if
you signed a service contract for Assist, certain
vehicle data can be sent directly from the vehi-
cle to facilitate the desired services.
