35nElectronic vehicle immobilizer
The key to security
Your BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the vehicle to theft
by making it impossible to start the
engine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for indi-
vidual keys (in the event of loss, for
instance). A deactivated key can no
longer be used to start the engine.
463de042
How the electronics work
At the heart of this system is an
electronic chip that is integrated into
the key. The lock mechanism itself is
actually a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine. <

46nElectric power windows Sliding/Tilt sunroof with glass moonroof*
Safety switch
With the safety switch, you can prevent
the rear windows from being opened or
closed via the switches in the rear
passenger area (by children, for
example). You can also prevent adjust-
ments of the power rear-seat backrests
from the rear passenger area (refer to
page 52).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury. <
530us021
To prevent injuries, exercise care
when closing the sliding/tilt
sunroof and keep it in your field of
vision until it is shut.
Before leaving the vehicle, switch off
the electric sunroof mechanism by
taking out the ignition key. Do not leave
children unattended in the vehicle with
access to vehicle keys. Use of the key
can result in starting of the engine and
operation of vehicle systems such as
the power sunroof, etc. Unsupervised
use of these systems can result in
serious personal injury. <
You can avoid pressure or drafts in the
passenger compartment when the
sunroof is open or lifted by opening the
air outlets in the instrument panel and
increasing the air supply as required.
Refer to pages 102 and 109.
If the sunroof is completely open, air
disturbances may be caused in the
vehicle when you are driving at higher
speeds. Close the roof as far as is
necessary until this natural phenom-
enon ceases.
For the convenience mode via the door
lock or the remote control, refer to
page 36 or 38.
Lifting – Opening – Closing
With the ignition key in position 1 or
higher, press the switch or slide it in the
desired direction until you feel resis-
tance.
The headliner insert slides back some-
what when you raise the sunroof. When
the sunroof is opened, the headliner
retracts with it.
When the top is up, do not try to
force the sunroof trim piece
closed, otherwise the mechanism will
be damaged. <
After the ignition has been switched off,
you can still operate the sliding/tilt
sunroof as long as neither of the front
doors has been opened.

0 Steering lock engaged
The key can only be inserted and
removed in this position.
After removing the key, turn the
steering wheel slightly to the left or right
until you hear the lock engage.
Once the ignition has been switched off
(ignition key in position 0 or pulled out),
the radio functions are still available for
approx. 20 minutes. Turn the radio back
on to use it.
An acoustic warning is sounded when
you fail to remove the ignition key after
opening the driver's door.

Vehicles with automatic trans-
mission:
Do not move the selector lever from the
"Park" position until the engine is
running (ignition key in position 2).
In order to turn the key to position 0 or
to remove it, first move the selector
lever to the "Park" position (Interlock). <
1 Steering lock disengaged
You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical devices are ready
for operation.
2 Ignition on
All electrical devices are ready for
operation.
3 Starting the engine
Vehicles with manual transmis-
sion: depress the clutch when
starting the engine. If you do not, a lock
prevents the engine from starting. <
Before starting
> Engage the parking brake.
> Be sure that the transmission
selector is in "Neutral" (or "Park" if
the vehicle is equipped with an auto-
matic transmission).
> Depress the clutch pedal.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard. <

65nStarting the engine Switching off the engine
Do not press the accelerator pedal
while starting the engine.
BMW 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.
BMW X5 4.4i:
Your BMW is equipped with the conve-
nience starting feature. Simply turn the
key to position 3 (starter) and then
release it immediately.
The starter continues to operate auto-
matically.
The automatic starting mode will not
operate if the battery voltage is low.
The engine can be started by means of
jump-starting (refer to page 190).<
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 very low temperatures,
from approx. +5 7 (–15 6) and at alti-
tudes above 3,300 ft (1,000 meters):
> For the initial start attempt, allow the
starter to remain engaged somewhat
longer (approx. 10 seconds).
> Press the accelerator pedal halfway
down while engaging the starter.
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 discharging,
always deactivate electrical devices
that are not in use. Switch the ignition
off when the vehicle is not being driven. Turn the ignition key to position 1 or 0.
Never remove the ignition key
while the vehicle is rolling. If you
did so, the ignition lock would engage
when the steering wheel is turned.
Always remove the ignition key and
engage the steering lock before leaving
the vehicle.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined
surfaces. Even placing the 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.

67nManual transmission
Press the clutch pedal all the way down
each time you shift, pressing the
manual-shift gear lever into its proper
end position.
Depress the clutch when starting the
vehicle, too, otherwise, lockout will
prevent the engine from starting if the
clutch is not depressed.
The shift lever's neutral gate (dot in the
illustration) is located between 3rd and
4th gear.
When shifting from each gear through
"Neutral," the shift lever returns auto-
matically to this neutral position
because of its spring loading.
360de044
Reverse
Select "Reverse" only when the vehicle
is completely stopped. Press the shift
lever to the left to overcome the resis-
tance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
A slipping clutch increases clutch
wear. <

68nAutomatic transmission with Steptronic*
You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. As soon as you briefly
touch the selector lever in the "+" or "–"
direction, Steptronic changes the gear.
The manual mode is engaged. When
you wish to use the automatic transmis-
sion mode again, move the selector
lever to the right into the "D" position.
The automatic transmission of your
BMW is equipped with Adaptive Trans-
mission Control (ATC), a system which
reacts with precision to your individual
driving style and the driving conditions.
530us040
To achieve this, different shift programs
are automatically engaged.
For additional details concerning the
ATC, please refer to the chapter
describing "Advanced technology" on
page 196.
Selector lever positions
P R N D M/S
The transmission range display varies
according to the equipment of your
vehicle (refer to the illustrations).
Starting the engine
The engine can only be started in
selector lever positions P ("Park") or N
("Neutral").
390us607
Range selection
A detent prevents inadvertent shifts to
the "Reverse" or "Park" selector lever
positions. To disengage the detent,
press the button on the front side of
the shift knob (arrow).
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. The vehicle will otherwise "creep"
when a drive position is engaged. <
If you leave the vehicle with the
engine running, move the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. If you fail
to do this, the vehicle could move.

69nAutomatic transmission with Steptronic*
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard. <
P — Park
Select "Park" only when the vehicle is
completely stopped. The transmission
locks to prevent the rear wheels from
turning.
R — Reverse
Select "Reverse" only when the vehicle
is completely stopped.
N — Neutral
Select "Neutral" only if your journey is
interrupted for a longer period.
D — Drive
(automatic shift program)
This position is designed for driving
under all normal operating conditions.
All forward gears are available.
"Kickdown"
In the "Kickdown" mode, you achieve
maximum performance.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S Manual mode and
Sport Program
When you change from D to M/S, the
Sport Program is activated. This is indi-
cated by "D S" in the gear selection
display. The Sport Program is designed
for performance-oriented driving.
With the first brief touch, the automatic
transmission shifts from the Sport
Program to the manual mode. When
you move the selector lever forward in
the "+" direction, the transmission shifts
up. When the lever is moved back in the
"–" direction, the transmission shifts
down. Depending on the equipment
version, 1 to 5 or M1 to M5 is indicated
in the transmission range display.
Upshifts or downshifts will only be
carried out by the ATC at appropriate
engine speeds and road speeds. If the
530us042
engine speed is too high, for instance,
the downshift will not be executed. The
gear selected will appear briefly in the
instrument cluster followed by the
current gear.
If you are driving in the manual
mode and wish to accelerate
rapidly – to pass another vehicle, for
example – shift down manually or with
the kickdown function. <
You can only change from M/S to
selector lever positions "P," "R" and "N"
via the "D" position.
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
> In order to prevent engine over-
speeding, the transmission shifts
automatically to the next higher gear
shortly before the RPM cutoff point.
> At low speeds, the transmission
shifts down automatically – you do
not have to act.
> In the "Kickdown" mode, the trans-
mission shifts down to the lowest
possible gear based on the engine
speed.
> Depending on the situation – when
driving in adverse winter conditions,
for example – you may also start out
in 2nd or 3rd gear.

70nAutomatic transmission with Steptronic*Indicator/Headlamp flasher
Electronic transmission control
module
If the indicator lamp comes on
or the message "TRANS.FAIL-
SAFE PROG" appears in the
Check Control
*, there is a fault in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to "P." Set
the parking brake and turn the engine
off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. You
may continue to drive as usual. If the
indicator lamp does not go out, you can
place the selector lever in all positions.
However, the vehicle will now only drive
forward with limited gear selection.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Do not work in the engine
compartment when a drive gear
(forward or reverse) is engaged. If you
do this, the vehicle could move. <
Information on jump-starting, tow-
starting and towing begins on
page 190.
