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.
Battery replacing
Only use vehicle batteries that have been
approved for your vehicle by the manu-
facturer; otherwise, the vehicle could be dam-
aged and systems or functions may not be fully
available.<
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort functions are fully
available.
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 page235.
Disposal
Have old batteries disposed of by your
BMW center or bring them to a recycling
center. Maintain the battery in an upright posi-
tion for transport and storage. Always secure the battery against tipping over during trans-
port.<
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
page76.
>Radio
In some cases, stations may have to be
stored again, refer to page147.
>Navigation system
Wait for the system to start, refer to
page141.
>Glass roof
It may happen that the roof can only be
tilted. 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
page107.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page89.
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.<

down.
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.
The first aid pouch is located on the right-hand
side of the cargo area in a storage area.
Warning triangle*
The warning triangle is located in a holder in the
trunk 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.<
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 to prevent sparking at the battery,
which could cause injury.<
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 page217. 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.

Giving and receiving assistance
236 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.<
Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
It is stored with the onboard vehicle tool kit
underneath the floor mat in the cargo area, refer
to page227.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. 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 could be damaged.<
