First-aid kit*
Beneath the front passenger's seat.
To open: pull the handle and fold the cover
downward.
To close: fold the cover up.
Some of the articles in the first-aid kit may be
used within a limited time only. Check the expi-
ration dates of the contents regularly and
replace the contents in a timely fashion as
needed.
Jump starting
When your battery is discharged, you can use
two jumper cables to start the engine of your
BMW with power from the battery in another
vehicle. You can also use the same method to
help start another vehicle. Use only jumper
cables with fully-insulated clamp handles.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully observe the following instructions to avoid
personal injury and/or damage to one or both
vehicles.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the vehicle provid-
ing assistance.
3.Switch off any electrical systems and com-
ponents in both vehicles.Ensure that no contact exists between
the bodywork on the two vehicles; other-
wise, there is a danger of short circuits.<
Connecting jumper cables
Connect the jumper cables in the correct
order; failure to do so could generate
sparks and cause injury.<
In your BMW, the so-called jump starting termi-
nal in the engine compartment functions as the
positive battery terminal, also refer to Engine
compartment overview on page93. The sym-
bol + is embossed on the cover.
1.Open the cover of the BMW jump starting
terminal, refer to arrow1.
2.Connect one terminal clamp of the posi-
tive/+ jumper cable to the positive terminal
of the battery or to a jump starting terminal
of the vehicle providing starting assistance.
3.Connect the second terminal clamp of the
positive/+ jumper cable to the positive ter-
minal of the battery or to a jump starting ter-
minal of the vehicle to be started.
Your BMW has a special nut that serves as the
body ground or negative terminal, refer to
arrow2.
4.Connect one terminal clamp of the nega-
tive/– jumper cable to the negative terminal
of the battery or to an engine or body
ground of the vehicle providing assistance.
5.Connect the second terminal clamp of the
negative/– jumper cable to the negative ter-
minal of the battery or to the engine or body
ground of the vehicle to be started.

Starting engine
1.Start the engine of the assisting vehicle and
let it run at a slightly elevated idling speed
for a few minutes.
2.Start the engine on the other vehicle in the
usual way.
If the first start attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
If need be, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
Tow starting and towing
Obey all applicable laws and guidelines
for tow starting and towing.<
Do not allow any passengers other than
the driver to ride in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit, refer to page99, and must
always remain in the vehicle. It can be screwed
in at the front or rear of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Use the tow fitting only for towing on roads.
Avoid lateral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting. Otherwise,
the tow fitting and the vehicle can be dam-
aged.<
Access to screw thread
Press out the cover in the front or rear bumper
at the notch at the bottom with a screwdriver.
Being towed
Make sure that the ignition key is in posi-
tion 1; otherwise, the steering lock will
engage, making it impossible to steer the vehi-
cle. There is no power assist with the engine
switched off. It is therefore necessary to exert
increased effort for braking and steering.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Do not exceed a towing speed of
30 mph/50 km/h and a towing distance of
95 miles/150 km; otherwise, the drive train may
be damaged.<
Manual transmission
Gearshift lever in neutral.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page38.
Towing methods
In some countries, towing with tow bars or
ropes on public roads is not permitted.
Familiarize yourself with the regulations on tow-
ing in the specific country.

With tow bar
The towing vehicle must not be lighter
than the vehicle to be towed; otherwise,
it will not be possible to safely control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited in corners.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fittings
only. Otherwise, other vehicle parts could
be damaged.<
With tow-rope
When starting off in the towing vehicle, make
sure that the tow-rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fittings only.
Otherwise, other vehicle parts could be dam-
aged.<
With tow truck
Do not tow the X3 with only the front or
rear axle raised; otherwise, the wheels
could lock and the transfer case could be dam-
aged.<
Have the X3 transported only on a flat bed.To avoid damage, do not lift the vehicle
from the tow fitting or body and suspen-
sion parts.<
Tow starting
If possible, do not tow start the vehicle; jump
start the engine instead, refer to page108.
Vehicles equipped with catalytic convertors
should only be tow started when the engine is
cold. It is not possible to tow start an engine
equipped with an automatic transmission.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on ignition, refer to page36.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Do not activate the HDC Hill Descent
Control during tow starting, refer to
page49.<
