Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
Display in the instrument cluster
1.Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button 2 in the turn indicator lever.
The oil level is checked and the reading dis-
played.

Vehicle battery
Battery care
The battery is 100 % maintenance-free, 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 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 page237.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page81.>Radio
In some cases, stations may have to be
stored again, refer to page166.
>Navigation system
Operability must be waited for, refer to
page132.
>Glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Seat and mirror memory
The positions must be stored again, refer to
page50.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page112.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, oth-
erwise this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
Open the cover in the glove compartment and
remove it.
Spare fuses and a pair of plastic forceps are set
in holders on the distributor box.
See the rear of the cover for information on fuse
assignment.

First aid pouch*
Some of the articles contained in the first aid
pouch have a limited service life. Therefore,
check the expiration dates of the contents reg-
ularly and replace any items in good time, if nec-
essary.
Coupe
The first aid pouch is located on the right-hand
side of the cargo bay in a storage area.
Convertible
The first aid pouch is located in a compartment
under the front passenger's seat.
To open: press the button and fold the cover
down.
To close: fold the cover back up and press it into
the catch.
Warning triangle*
Coupe
The warning triangle is located on the left-hand
side of the cargo bay. Press the tab to take it
out.
Convertible
The warning triangle is located in a holder in the
luggage compartment lid. Press the tabs to take
it out.
Jump starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Carefully adhere to the follow-
ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.<

Giving and receiving assistance

Preparation
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 assisting vehi-
cle.
3.Switch off any consumers in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
Connect the jumper cables in the correct
order, so that no sparks which could
cause injury occur.<
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page225. The cap is
marked with +.
1.Pull the cap of the BMW jump-starting con-
nection up to remove.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a starting-aid terminal of
the vehicle to be started.
4.Attach one terminal clamp of the minus/–
jumper cable to the negative terminal of the
battery or to an engine or body ground of
the assisting vehicle. Your BMW has a special nut as body ground
or negative pole.
5.Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
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 above connecting sequence.
If necessary, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
Tow-starting, towing away
Observe the applicable laws and regula-
tions for tow-starting and towing vehi-
cles.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<

Giving and receiving assistance
240
With a 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 the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
With a tow truck: vehicle without xDrive
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With a tow truck: vehicle with xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page237. Vehicles with a catalytic converter
should only be tow-started when the engine is
cold, vehicles with an automatic transmission
cannot be tow-started at all.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page59.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely 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.
With xDrive: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page90.<
