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. There-
fore, check the expiration dates of the contents
regularly and replace the contents in a timely
fashion as needed. You can find replacements
in any pharmacy. Always observe all legal regu-
lations requiring a first-aid kit to be carried in the
vehicle.<
Jump starting
When your battery is discharged, you can use
two jumper cables to start your vehicle with
power from the battery in a second 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
To avoid personal injury from sparks,
always follow this sequence when con-
necting jumper cables.<
On your BMW, the auxiliary terminal for jump
starting in the engine compartment serves as
the battery positive terminal, refer also to
engine compartment overview on page89.
The symbol + is embossed on the cover.
1.Open the cover of the BMW auxiliary termi-
nal for jump starting, refer to arrow1.
2.Connect one terminal clamp of the posi-
tive/+ jumper cable to the positive terminal
of the battery or an auxiliary 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 an auxiliary termi-
nal 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.Attach one end of the jumper cable minus/–
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 assisting vehicle's engine and let it
run at an increased 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 necessary, have the battery checked and
recharged at a BMW Sports Activity Vehicle
Center.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Use tow fitting
The threaded tow fitting is stored in the
onboard tool kit, refer to page95, and must
always remain in the vehicle. It can be screwed
in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as it will go. Only use the tow
fitting to tow on roads. Avoid lateral loading of
the tow fitting, e.g. do not lift the vehicle by the
tow fitting.<
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, as otherwise the steering lock will
engage, making it impossible to steer the vehi-
cle. There is no power assist with the engine
stopped. It is then 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, as otherwise the drive train
may be damaged.<
Vehicles with manual transmission
Gear lever in neutral.
Vehicles with automatic transmission
Selector lever in N.
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 respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<

106 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 fitting only.
Otherwise damage could result on other
vehicle parts.<
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 on the tow fitting only.
Otherwise damage could result on other vehicle
parts.<
With tow truck
Do not tow the X3 with only the front or
rear axle raised, as otherwise the wheels
could lock and the transfer case could be dam-
aged.<
Only have the X3 transported on a load bed.
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page104.<
Vehicles with a catalytic converter should only
be tow-started when the engine is cold. It is bet-
ter to jump start the engine, refer to page104.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
3.Engage the 3rd gear.
4.Have the vehicle tow-started with the clutch
pedal completely depressed and slowly
release the clutch. After the engine starts,
immediately depress the clutch pedal com-
pletely 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
page48.<
