Replacing components
212
Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. You must be duly diligent
in replacing them. BMW recommends having
your BMW center perform any work that you do
not feel competent to perform yourself or that is
not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean cloth, napkin, etc., or hold the bulb by its
metal socket.<
A selection of replacement bulbs is available at
your BMW center.
Whenever you perform any work on the
electrical system, turn off the consumers
involved to prevent short circuits from occur-
ring. To avoid possible injury or equipment
damage when replacing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
For bulbs for which changing is not
described, and for checking and adjusting
headlamp aim, please contact your BMW cen-
ter.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Halogen headlamps
The illustration shows the left-hand side of the
engine compartment.1Cover cap for low beams
2Cover cap for high beams
Turn the cover cap to the left and remove.
Always wear gloves and eye protection –
the atmosphere within the H7 bulb is
pressurized. Otherwise there is a danger of inju-
ries if the bulb is accidentally damaged during
replacement.<

face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the specified torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Battery care
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 off. Connections, refer to Jump starting
on page220.

Giving and receiving assistance
220
Sports Wagon
Release the two quick-release fasteners and
fold down the trim piece.
First-aid kit*
Some of the articles contained in the first-aid kit
have a limited service life. Therefore, check the
expiration dates of the contents regularly and
replace the contents concerned in good time if
necessary.
Sedan
The first-aid kit is located in the luggage com-
partment lid.
Loosen the wing nut to open.
Sports Wagon
The first-aid kit is located in the right side panel
of the cargo area. Before opening the side
panel, pull the retaining strap
* toward the rear
by its rear end and unhook it.
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
Contact brochure.
With BMW Assist or TeleService, you can con-
tact the Roadside Assistance of the BMW
Group for assistance in the event of a break-
down directly via iDrive, refer to page189.
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.<

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 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 shorting.<
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
page205. The cover cap is marked with a +.
1.Fold 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 provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a start-
ing-aid 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 assisting
vehicle.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 screw-on tow-fitting must always be car-
ried in the vehicle. It can be screwed in at the
front or rear of the BMW.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
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.
Only attach tow ropes to the tow fittings, 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.
With tow truck for 525xi, 530xi
Do not tow the BMW with xDrive with the
front or rear axle raised individually, other-
wise the wheels may block and the transfer
case may be damaged.<
The BMW may only be transported 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 page220. 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.<
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
