catalytic converter BMW X5 4.4I 2005 E53 Owner's Manual

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, as
otherwise the lambda probe and
catalytic converter will be permanently
damaged.<
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 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.
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, however at the latest after
approx. 20 seconds. Release the igni-
tion key immediately as soon as the
engine starts.
X5 4.4i, 4.8is:
Your BMW is equipped with the conve-
nience starting feature. Here, it is suffi-
cient 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 operate 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 page171.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 discharg-
ing, 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, as
otherwise the steering could lock.
When leaving the vehicle, always
remove the ignition key and lock the
steering.
Vehicles with 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.
Vehicles with automatic transmission:
Place the selector lever in Park.<
Vehicles with automatic transmission:
The vehicle must be stationary and the
selector lever in Park before you can
remove the ignition key.

General driving notesClosing liftgate/tailgate
Operate the vehicle only when the
tailgate and liftgate are completely
closed. Otherwise, exhaust fumes
could enter into the passenger com-
partment.<
However, if special circumstances
should make it absolutely necessary
to operate the vehicle with the liftgate/
tailgate open:
1. Close all windows and the panorama
glass sunroof
2. Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page108 or112.
Hot exhaust system
Extreme temperatures occur at
the catalytic converter on this and
every catalyst-equipped vehicle. Do not
remove the heat shields installed adja-
cent to various sections of the exhaust
system, and never apply undercoating
to them. When driving, standing at idle
and while parking take care to avoid
possible contact between a hot exhaust
system and any highly flammable mate-
rials such as hay, leaves, grass etc.
Otherwise there is a danger of ignition
and of a fire with the risk of serious inju-
ries and damage. BMW advises against using
mobile radio devices such as por-
table phones inside the vehicle unless
they are directly connected to the
external antenna. Otherwise, it is
impossible to prevent a mutual interfer-
ence of the vehicle electronics with the
portable phone device. Also, there is no
guarantee that the radiation generated
by the transmission will be conveyed
out from the interior of the vehicle.<
When vehicle is parked Condensation forms in the air condi-
tioner system during operation, and
then exits under the vehicle. Traces of
water on the ground are therefore nor-
mal.Brakes
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
excessively high temperatures, brake
wear and possibly even brake failure.<
Road hazards
If road hazards, obstacles or curbs
are unavoidable, only drive over
them very slowly and carefully, as oth-
erwise the wheels and suspension
parts, especially on vehicles fitted with
low profile tires, can be damaged.<
For more information on wheels and
tires, refer to page144.
Before driving into a car washFold in the exterior mirrors, refer to
page54, as otherwise they could be
damaged due to the width of the vehi-
cle.Hydroplaning
When driving on wet or slushy
roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
state can cause a partial or total loss of
contact with the road surface, of brak-
ing control and of control over the vehi-
cle.<

OBD interface socketThe interface socket for the Onboard
Diagnostic is located on the left of the
driver's side at the bottom of the instru-
ment panel 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
Indication of the above-
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
will light up. If the filler cap is subse-
quently 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.
