Changing a wheel
Safety measures in the event of a
breakdown or wheel change:
Park the vehicle as far away as possible
from moving traffic and on firm ground.
Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead
setting of the wheels. Apply the handbrake
and engage first gear, reverse gear or
selector lever to position P.
Have all vehicle occupants get out of the
vehicle and ensure that they remain outside
the immediate area in a safe place, such as
behind a guardrail.
If a warning triangle or portable hazard
warning lamp is required, set it up on the
roadside at an appropriate distance from
the rear of the vehicle.
Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm sur-
face which is not slippery.
The vehicle or the jack could slip to the side
if you attempt to raise the vehicle on a soft
or slippery surface such as snow, ice, tiles,
etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need
To avoid rattling noises later on, note the
positions of the tools before removing
them, then return them to their initial posi-
tions after completing work.1Chock
2Vehicle jack

are located in the tool space in the rim of
the compact wheel. Raise the floor mat and
the cover beneath it. Take out the required
tool(s). After using the tools, return them to
the storage space.
Compact wheel*
1.Unscrew the wing nut 1
2.Remove the disk 2 to the side
3.Take out the tool brackets 3
4.Remove the compact wheel.
Procedure
1.Read carefully and comply with the
safety precautions on left-hand column
2.To secure the vehicle against move-
ment:
Place the wheel chock behind the front
wheel on the side opposite the side
being raised. If the vehicle is parked on
a downward slope, place the chock in
front of the wheel. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from rolling

Charging the battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page 192.
Disposal
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Always restrain the bat-
tery 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.<
Spare fuses, plastic tweezers and details of
the fuse assignment are located in the
compartment for the onboard tool kit, refer
to page 184.
In the glove compartment
Turn the two snap fasteners outwards. Fold
the cover forwards or remove.
In the luggage compartment
Raise the floor mat and the cover beneath
it. Undo the screw connection of the right
side panel and pull out the panel.

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 adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injuries.<
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 consumer units in both
vehicles.
There must not be any contact
between the bodies of the two vehi-
cles, as 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 so-called starting-aid
terminal in the engine compartment serves
as the battery positive terminal, refer also
to Engine compartment overview on
page 178. The symbol + is embossed on
the cover.
1.Open the cover of the BMW starting-aid
terminal. To do so, pull the tab
2.Attach one end of the jumper cable
plus/+ to the positive terminal of the
battery or a starting-aid terminal of the
vehicle providing assistance
3.Attach the second end of the cable to
the positive terminal of the battery or to
a starting-aid terminal of the vehicle to
be started
Your BMW has a special nut as body
ground or negative pole.
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.Attach the second end of the cable to
the negative terminal of the battery or to
the engine or body ground of the vehi-
cle to be started.
Starting the engine
1.Start the engine on the support vehicle
and allow it to run for several minutes at
a fast idle
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.Let the engines run for a few minutes
4.Disconnect the jumper cables by
reversing the connection sequence.
If required, have the battery inspected and
recharged at your BMW center.
Never use spray fluids to start the
engine.<
Towing
Always observe all applicable towing
laws and regulations.<
Towing with a commercial tow truck
>Use a wheel lift or flatbed carrier
>Do not tow with sling-type equipment.
Never allow passengers to ride on a
towed vehicle for any reason.<
Towing with raised front axle
Vehicles with automatic
transmission:
1.Towing speed:
Maximum 45 mph/70 km/h
2.Towing distance:
Maximum of 90 miles/150 km.
Vehicles with Sequential manual
transmission SMG
With the ignition switched on, engage the
selector lever position N, then switch off
the ignition again.
Tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment lid, refer to page 184, and
should always remain in the vehicle. It can
be screwed to the front or rear of the vehi-
cle.
