Starting the engine Before starting >Engage the parking brake.
>Be sure that the selector lever is in
"Park" position.
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.<
Do not press the accelerator pedal
while starting the engine.
Your BMW is equipped with the
convenience starting feature. Sim-
ply turn the key to position 3 (starter)
and then release it immediately. The
starter continues to operate automati-
cally.
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 170).<
Do not allow the engine to warm up by
leaving it running while the vehicle re-
mains 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 the starter is engaged.
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 deactivate electrical de-
vices that are not in use. Switch the ig-
nition off when the vehicle is not being
driven.

Automatic transmission with Steptronic 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 rap-
idly Ð to pass another vehicle, for exam-
ple Ð shift down manually or with the
kickdown function.<
You can only change from M/S to se-
lector 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 Ð 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 Ð when
driving in adverse winter conditions,
for example Ð you may also start out
in 2nd or 3rd gear.
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 en-
gine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual. If the indica-
tor lamp does not go out, you can place
the selector lever in all positions. How-
ever, the vehicle will now only drive for-
ward with limited gear selection.
If this should occur, avoid extreme en-
gine loads and consult the nearest au-
thorized BMW center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.<

ing and towing begins on page 170.

Battery Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump-starting" on page 170).
The service life specified for the
battery can be achieved only if it
is always kept adequately charged.
Have the charge condition of the bat-
tery checked frequently if the vehicle
is used primarily for driving short
distances.<
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to park the vehicle longer
than 4 weeks, have the battery discon-
nected from the vehicle's electrical
system by disconnecting the cable from
the negative terminal. Then have the
battery charged with an appropriate
battery charger.
If the vehicle will not be driven for a
period longer than 12 weeks, have the
battery removed, charged and store it
in a clean and cool (frost-free) area.
Recharge the battery at least every
three months during storage. Also,
recharge the battery before it is in-
stalled. If you fail to do so, it will not be
serviceable. Every time the battery is
discharged, especially over extended
periods, its service life is reduced. Do not disconnect the battery
when the engine is running. If
you do so, the ensuing voltage surge
will damage the vehicle's onboard elec-
tronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting in
transit.<

170n
Do not use spray starter fluids to start
the engine.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of an-
other vehicle. Always use jumper ca-
bles with fully insulated handles on the
terminal clamps.
Do not touch the parts conducting
current while the engine is run-
ning. Failure to comply with this creates
a risk of fatal injury.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Be sure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing).
2 Leave your battery connected to the
vehicle's electrical system.
3 Make sure that there is no contact
between the bodywork of the two
vehicles Ð this creates a risk of short
circuits.
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's en-
gine compartment The cover of the
auxiliary terminal for jump starting is
marked with a "+" sign (refer to the il-
lustration). To remove the cover, tip
up the cap (arrow). 530us126
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (-),
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the ve-
hicle that is to be started. There is a
special nut for this on the left side
panel of your BMW. Refer to the ar-
row in the illustration.
Follow the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
generate at the battery.< 530us127
Jump-starting

171n
Jump-starting Towing the vehicle 6 Start the engine on the support
vehicle and let it run.
7 Start the engine on the vehicle need-
ing the jump-start, and allow it to run
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge.
8 Before disconnecting the jumper ca-
bles from your BMW, turn on the rear
window defroster and set the blower
to the highest speed; allow the en-
gine to run approx. 10 seconds. This
will prevent a voltage surge from the
voltage regulator to the electrical ac-
cessories.
9 Then disconnect the jumper cables in
reverse sequence.
Have the battery recharged if neces-
sary.
Tow fitting The screw-in tow fitting is stored be-
neath the cargo area floor. Carry it with
you at all times. This fitting is designed
for installation in the tow sockets lo-
cated at the front and rear of the vehi-
cle, and is intended for towing on
paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations. Access to tow sockets Front:
Use a screwdriver on the left or right
side (arrows) to press the cover out . 530us128
Rear: pull the cover off.
Screw the tow fittings in until they
are tight. If you do not, the threads
could be damaged.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do so, the com-
ponents could be damaged, leading to
possible accidents.<
Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.< 530us129
