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.<

Manual transmission:
Depress the clutch when starting
the engine. If you do not, a lock pre-
vents the engine from starting.<
Before starting >Engage the handbrake
>Be sure that the gearshift lever is in
Neutral or the selector lever in Park if
the vehicle is equipped with an auto-
matic transmission
>Depress the clutch.
If the clutch is not depressed, the
engine cannot be started
>Press the footbrake with an auto-
matic transmission.
Do not run the engine in closed
rooms, otherwise the inhalation of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust
gases contain carbon monoxide, 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 select neutral or the position P
and engage the handbrake before leav-
ing the vehicle with the engine run-
ning.<
When starting the engine, do not press
the accelerator pedal.

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.

Handbrake Manual transmissionThe handbrake is primarily intended to
prevent the vehicle from rolling while
parked; it brakes the rear wheels.EngagingThe lever engages automatically when
you pull it up and the indicator lamp
comes on in the instrument cluster in
ignition key position 2, refer to
pages 19, 21.Releasing Pull up slightly on the lever, press the
button and lower the lever. 530de262
If exceptional circumstances
should make it necessary to
engage the handbrake while the vehicle
is in motion, do not pull it too strongly.
In doing so, continuously press the but-
ton of the handbrake lever. Otherwise
strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle
rear end.
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 Park.<
To prevent corrosion and one-
sided braking action, occasionally
apply the handbrake lightly when the
vehicle is slowly coming to a stop if the
traffic conditions are suitable.
The brake lamps do not light up when
the handbrake is applied.
Press the clutch all the way down each
time you shift, pressing the gearshift
lever into its proper end position.
Depress the clutch when starting the
vehicle, too. If the clutch is not
depressed, the interlock will prevent the
engine from starting.
While shifting in the 5th/6th gear
slot, press the gearshift lever
toward the right, otherwise, accidental
shifting into the 3rd or 4th gear could
result in engine damage.< 380de044

Upshifts and downshifts are executed
only when they will result in a plausible
combination of engine and vehicle
speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system. The
gear selected will appear briefly in the
instrument cluster and then the current
gear will reappear.
To return to automatic mode, move the
selector lever toward the right into posi-
tion D.
