Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
dashboard.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.<
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to a BMW Assist plan, then certain vehi-
cle data can be transmitted or recorded to
enable corresponding services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.

Changing wheels
Your BMW is equipped with run-flat tires as a
standard feature. An immediate wheel change
in the event of a flat tire is therefore no longer
required.
To continue driving with a damaged tire,
>With Flat Tire Monitor, refer to Indication of
a flat tire, page89
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure,
page91
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires on page192.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires because no spare tire is provided in
case of a flat. Your BMW center will be glad to
advise you.
Also refer to New wheels and tires, page192.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Car jacking points
The jacking points for the car jack are located in
the positions shown.
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 center will be glad to advise in all
matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page207.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
Power failure
Following a temporary interruption of the power
supply, the operation of some equipment is lim-
ited and must be reinitialized. Individual settings
are also lost and must be updated:

Roadside Assistance*
The Roadside Assistance of the BMW Group
offers you assistance in the event of a break-
down around the clock, including on weekends
and public holidays.
The phone numbers of the Roadside Assis-
tance in your home country can be found in the
BMW Contact directory.With BMW Assist or TeleService, you can con-
tact the Roadside Assistance of the BMW

down directly via iDrive, refer to page181.
Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW 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 adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible 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 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.
There must not be any contact between
the bodies of the two vehicles; otherwise,
there is a danger of short circuiting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
In your BMW, the so-called auxiliary terminal
for jump starting in the engine compartment
serves as a positive terminal for the battery, also
refer to engine compartment overview on
page195. The cover cap is marked with a +.

Giving and receiving assistance
208 1.Fold open the cover of the BMW jump-
starting 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 provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a jump-
starting terminal of the vehicle to be started.
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.
Your BMW has a special nut as body ground
or negative terminal.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Starting engine
1.Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting 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.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page201, and
should 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 possi-
ble. Use the tow fitting for towing only 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 vehicle can be damaged.<

Being towed
Make sure that the ignition is switched on,
refer to page58; otherwise, the low-beam
headlights, tail lights, turn signals and wind-
shield wipers would not be available. If the vehi-
cle electrical system fails, do not tow-start or
tow the vehicle. The electric steering-wheel
lock cannot be unlocked and the vehicle cannot
be steered. For information on jump starting,
refer to page207. There is no power assistance
with the engine stopped. This then requires
increased effort for braking and steering. Active
steering is deactivated and larger steering
wheel movements are required.<
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 position.
Automatic transmission
Selector lever in position N.
Changing selector lever position, refer to Deac-
tivating selector lever interlock page63.
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.<
SMG Sequential Manual Transmission
Engage selector lever position N with the igni-
tion switched on.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts; otherwise, damage
may result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed; otherwise, it
will not be possible to reliably 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 note the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Attach the tow bar to the tow fittings only,
as attachment to other vehicle parts can
lead to damage.<
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.
Attach tow ropes to the tow fittings only, as
attachment to other vehicle parts can lead to
damage.<

With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page207. With a catalytic con-
verter, tow-starting should only be carried out
with the engine cold, and with automatic trans-
missions, the engine cannot be started by tow-
starting.
If the electrical system fails, do not tow-
start or tow the vehicle, as otherwise the
electric steering-wheel lock cannot be
unlocked and the vehicle cannot be steered.<
