2008 BMW X3 3.0SI battery

Replacing components
114 Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages54, 55.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page117.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page31.
>Time
Must be set again, refer to page47.

First-aid kit*
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.
The first-aid kit is located under the front pas-
senger's seat.
To open: pull the handle and fold the cover
downward.
To close: fold the cover up.
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 comply with 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 there is no contact 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 page101. The
symbol + 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.
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.
Your BMW has a special nut that serves as
the body ground or negative terminal, refer
to arrow2.
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.

Giving and receiving assistance
118
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 page107, 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
Front
Push the cover in the bumper out of the recess
with a screwdriver.
Rear
Press on the mark provided on the cover.
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.
Manual transmission
Gearshift lever in neutral.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page40.
Do not exceed a towing speed of
45 mph/70 km/h and a towing distance
of 90 miles/150 km; otherwise, the automatic
transmission may be damaged.<
