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.<

sion:
Only move the selector lever from posi-
tion P with the engine running.
To turn the key back to position 0 or to
remove it, first place the selector lever
in position P: interlock.<
Steering lock disengaged Slightly moving the steering often
makes it easier to turn the key from 0
to 1.
Individual current consumers are ready
for operation. Starting engine
Vehicles with manual transmis-
sion:
Depress the clutch pedal 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
>Press the clutch pedal.
If the clutch pedal is not depressed,
the engine cannot be started
>In vehicles with automatic transmis-
sions, depress the footbrake.
Do not run the engine in closed
rooms, as otherwise the inhaling
of toxic exhaust gases can cause
unconsciousness and death. The
exhaust gases contain carbon monox-
ide, 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, 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

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
pages19, 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.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not light up when
the handbrake is applied.
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.<
To avoid corrosion, apply the hand-
brake lightly from time to time when
coasting to a standstill at a traffic signal,
for instance, provided that it is safe to
do so.
Press the clutch pedal all the way down
each time you shift, pressing the gear-
shift lever into its proper end position.
Depress the clutch when starting the
vehicle, too, otherwise, the interlock will
prevent the engine from starting if the
clutch is not depressed.
While shifting in the 5th/6th gear
lane, press the selector lever
toward the right, as otherwise acciden-
tal 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 followed by the cur-
rent gear.
In order to go back to using automatic,
move the selector lever toward the right
into position D.
