catalytic converter BMW X5 3.0I 2004 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
determined 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 engineWhen starting the engine, do not press
the accelerator pedal.
X5 3.0i:
Do not actuate the starter for too
short a time. Do not turn it for more
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. 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 started by jump-starting, refer to
page 171.<
Do 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.
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. Engage first gear or reverse gear.
Automatic transmission:
1. Engage 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 notesHot 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.
Such contact could lead to a fire, and
with it the risk of serious property dam-
age as well as personal injury.<
Parking vehicle Condensation forms in the air condi-
tioner system during operation, and
then exits under the vehicle. Traces of
condensed water under the vehicle are
thus normal.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
otherwise 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 page 143.
Before driving into a car washFold in the door mirrors, refer to
page 54, 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.<
Driving through water
Do not drive through water on
the road if it is deeper than 20 in/
50 cm, and then only at walking speed
at the most. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.<

OBD interface socket
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.
Display of the previously
described malfunction on 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 go out within a few days.<

Towing and tow-starting vehicleTow-starting
Do not tow-start vehicles with an
automatic transmission.
For information on jump-starting, refer
to page 171.<
Only tow-start vehicles with a catalytic
converter with the engine cold. It is bet-
ter to jump-start the engine, refer to
page 171.
1. Switch on the hazard warning flash-
ers and observe local regulations
2. Turn the ignition key to position 2
3. Engage the 3rd gear
4. Tow-start with the clutch pedal com-
pletely depressed and slowly release
the clutch pedal. After the engine
starts, immediately depress the
clutch pedal completely again
5. Stop at a suitable location, remove
the tow bar or rope and switch off
the hazard warning flashers
6. Have the vehicle checked.
Do not activate the HDC Hill
Descent Control during tow-
starting, refer to page 96.<
