2006 BMW X5 3.0I catalytic converter

26n
Fuel specifications The engine uses lead-free gasoline
only.Required fuelPremium Unleaded Gasoline,
Minimum Octane Rating: 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called
(R+M)/2 method.
Do not use leaded gasoline: use of
leaded fuel will permanently dam-
age the lambda probe and catalytic
converter of your vehicle.<
Use high-quality brandsField experience has indicated signifi-
cant differences in fuel quality: volatility,
composition, additives, etc., among
gasolines offered for sale in the United
States and Canada. Fuels containing up
to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % meth-
anol plus an equivalent amount of co-
solvent, 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 cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude.
Should you encounter drivability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching to
a recognized high-quality brand.
Failure to comply with these recom-
mendations may also result in unsched-
uled maintenance.<

Starting engine Switching off engineDo not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.
X5 3.0i:
Do not end the starting procedure too
soon, but do not continue for longer
than approx. 20 seconds. Release the
ignition key immediately as soon as the
engine starts.
X5 4.4i, 4.8is:
Your BMW is equipped with the conve-
nience starting feature. With this fea-
ture, it is sufficient to turn the ignition
key only briefly to position 3 'Start
engine' and to let go of it right away.
The starter actuation continues to oper-
ate automatically for a certain period of
time and is stopped automatically as
soon as the engine has started.
The automatic starting mode will not
operate or will be canceled if the bat-
tery voltage is insufficient. The engine
can be jump started, refer to page174.Should the engine fail to start on the
first attempt, if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at altitudes above 3,300 ft/
1,000 meters and at very low tempera-
tures, from approx. +57/–156:
>For the initial starting attempt, allow
the starter to remain engaged some-
what longer, approx. 10 seconds.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from being
drained, always switch off electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to damage of the
catalytic converter.<
Manual transmission:
1. Turn the ignition key to position 1
or 0
2. Shift into first gear or reverse.
Automatic transmission:
1. Shift into selector lever position P
2. Turn the ignition key to position 1
or 0.
Do not remove the ignition key
when the vehicle is moving, other-
wise, the steering could lock.
When leaving the vehicle, always
remove the ignition key and lock the
steering.
Manual transmission:
Always engage the handbrake when
parking on slopes and inclined sur-
faces. Even placing the gearshift lever
in 1st gear or reverse may not provide
adequate resistance to rolling.
Automatic transmission:
Place the selector lever in the P posi-
tion.<
Automatic transmission:
The vehicle must be stationary and the
selector lever in Park before you can

OBD interface socketThe interface socket for the Onboard
Diagnostics is located on the left of the
driver's side at the bottom of the instru-
ment cluster and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deteriora-
tion and malfunction.
An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity. 530us105
Display of the previously
described malfunction in Cana-
dian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire.
When this occurs, you should reduce
speed and consult the nearest BMW
Sports Activity Vehicle center as soon
as possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is sub-
sequently tightened, the indicator lamp
should extinguish within a few days.<
Event Data Recorders Your vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agree-
ment for the BMW Assist system, cer-
tain vehicle information may be trans-
mitted or recorded in order to provide
such services.

Tow-starting and towing>The freedom of movement is
restricted during cornering
>The angled position of the tow bar
creates lateral forces.
Only attach the tow bar to the tow
fittings, as attachment to other
vehicle parts can lead to damage.<
With tow-rope:
When starting off in the towing vehicle,
make sure that the tow-rope is taut.
Use nylon ropes or nylon straps
for towing, and avoid all exces-
sively sudden jerking movements. Only
attach tow ropes to the tow fittings, as
attachment to other vehicle parts can
lead to damage.<
With tow truck:
Do not tow the X5 with the front or
rear axle raised individually, other-
wise the wheels may lock and the
transfer case may be damaged.<
The X5 may only be transported on a
flat bed.530de403
Tow-starting
Do not tow-start vehicles with an
automatic transmission.
For information on jump starting, refer
to page174.<
