2004 BMW X3 3.0I engine

Replacing components
106
Charging the battery
Charge the battery in the vehicle only when
the engine is not running. Use the connec-
tions provided in the engine compartment.
For correct connections, refer to Jump-
starting on page 108.
Disposal
Bring old batteries to a collection
point or your BMW Sports Activity
Vehicle Center. Maintain the battery in an
upright position for transport and storage.
Always restrain the battery to prevent it
from tipping over during transport.<
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Open the glove compartment and turn the
two quick-release fasteners to the left,
refer to arrows.
Spare fuses, plastic tweezers and details of
the fuse assignment are located in the
compartment for the onboard tool kit.

Giving and receiving assistance
108
Warning triangle*
To open the side trim panel: press the but-
ton.
Comply with legal requirements
requiring you to carry a hazard warn-
ing triangle in the vehicle.<
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. For this reason, check the expiration
dates of each of the items regularly, and
replace any whose expiration dates have
passed. You can find replacements in any
pharmacy.
Always observe all legal regulations
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. Carefully 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 battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits.<
Connecting the jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
On your BMW, the auxiliary terminal for
jump-starting in the engine compartment
serves as the battery positive terminal,

on page 93. The symbol + is embossed on
the cover.
1.Open the cover of the BMW auxiliary
terminal for jump-starting, refer to
arrow 1
2.Connect one terminal clamp of the pos-
itive/+ jumper cable to the positive ter-
minal of the battery or a auxiliary termi-
nal of the vehicle providing starting
assistance
3.Connect the second terminal clamp of
the positive/+ jumper cable to the posi-
tive terminal of the battery or to a auxil-
iary terminal of the vehicle to be started.
On your BMW, there is a special nut as
body ground or negative terminal on the
suspension strut dome, refer to arrow 2
4.Attach one end of the jumper cable
minus/Ð 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/Ð jumper cable to the neg-
ative terminal of the battery or to the
engine or body ground of the vehicle to
be started.
Starting the engine
1.Start the support 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 success-
ful, wait a few minutes before another
attempt in order to allow the discharged
battery to recharge
3.Allow the engines to run for several
minutes
4.Disconnect the jumper cables by
reversing the connection sequence.
If necessary, have the battery checked and
recharged at a BMW Sports Activity Vehi-
cle Center.
Never use spray fluids to start the
engine.<
Towing
Always observe all applicable towing
laws and regulations. Do not tow the
BMW X3 with the axle raised, as otherwise
the transfer case can be damaged.<
Towing with a commercial tow truck
>Use only a flatbed carrier
>Do not tow with sling-type equipment
>Do not use a wheel lift.
Never allow passengers to ride on a
towed vehicle for any reasons.<
Tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the compart-
ment and should always remain in the vehi-
cle. This fitting is designed for installation in
the tow sockets located at the front and
rear of the vehicle.
Access to tow sockets
Front
Use a screwdriver to lever out the cover
upward at the recess.
