The luggage compartment lid is locked and
cannot be unlocked using the central locking
system.
If you give the remote control without the inte-
grated key to someone else while the glove
compartment is locked, the luggage compart-
ment lid cannot be opened. This is an advan-
tage when valet parking, for example. Locking
the glove compartment, refer to page87.
Unlocking separately
Push the switch in the direction of arrow 2.
Emergency release
Pull the lever in the cargo bay. The luggage
compartment lid is unlocked.
Closing
The handle recesses on the interior trim of the
luggage compartment lid make it easier to pull
down.Make sure that the closing path of the
luggage compartment lid is clear, other-
wise injuries may result.<

Convertible
To close the luggage compartment lid,
press it down lightly. The lid is closed
automatically.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>To movements inside the vehicle: Interior
motion sensor, refer to page26
>When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away
>When there is an interruption in the power
supply from the battery
The alarm system signals unauthorized entry
attempts for a short time by means of:

Driving
52 4.Insert the screwdriver into the opening of
the white lever, arrow 1.
5.Pull the screwdriver back all the way, arrow
2. The transmission lock is released.
6.Carefully remove the screwdriver, for exam-
ple to avoid accidentally engaging the
transmission lock during towing.
After parking the vehicle, lock the trans-
mission lock again. Otherwise there is a
danger of the vehicle rolling.<
Locking
1.Insert the screwdriver into the opening of
the white lever and press forward.
The transmission lock is locked again.
2.Fold back the black cover until it engages
audibly.
3.Clip the sleeve of the selector lever back
into place.
Jump-starting and towing, refer to page137.
Drivelogic
Various drive programs are available to you via
Drivelogic.
After every change between sequential and
drive mode, the program selected last in each
case is active. Exception: after the first change from sequential to drive mode, drive program 3
is active.
In drive mode
Five drive programs are available for selection,
from winter program/balanced 1 to sporting and
highly dynamic 5.
In sequential mode
You can choose between six drive programs,
from winter program/balanced 1 to sporty
puristic 6.
Program 6 is available when Dynamic Stability
Control is deactivated, refer to page68. If DSC
is activated, the program changes from 6 to 5.
To maintain driving stability, activate DSC
whenever possible.<
Selecting the drive program via the
button in the center console
Press the button repeatedly until the desired
drive program is displayed in the instrument
cluster, refer to page51.
Shift Lights
To achieve the best possible acceleration in
sequential mode when using a sporty driving
style, the Shift Lights in the instrument cluster
indicate the best shift point just before the max-
imum engine speed is reached.

Things to remember when driving
100 during brake applications to clean the rotors is
not reached.
This can also lead to a permanent loss in ride
comfort and to squealing noises during braking.
A loss in comfort can also be caused by
extended braking with little pressure on the
pedal.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
For information on brake system technology,
refer to Compound brake on page103.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blow-out.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
bay, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.

Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.

ConvertibleSecuring cargo
Coupe
Convertible
Convertible: before opening the hardtop,
fold down the cargo bay partition. Make
sure the cargo bay is loaded correctly, other-
wise parts of the hardtop can be damaged, refer
to page91.<
>Secure smaller and lighter items using
retaining straps, a cargo bay net
* or draw
straps
*.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes are
provided for attaching the cargo straps.
Two are located on the cargo bay
sidewalls1, two more are on the rear cargo
bay panel2.
Please comply with the information sup-
plied with the cargo straps.
Position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page155, as excessive loads can pose a

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 page117. 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

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.
Coupe: it is stored in the onboard tool kit under-
neath the cover on the right-hand side of the
cargo bay, refer to page127.
Convertible: it is stored in the onboard tool kit
underneath the cargo bay floor, refer to
page127.
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.<
Access to screw thread
Release the cover panel in the bumper:
Press on the upper part of the cover panel.

Rear
Being towed
Make sure that the ignition is switched on,
refer to page46, otherwise the low-beam headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Manual transmission
Gearshift lever in neutral position.
M dual clutch transmission with
Drivelogic
Ensure that the parking lock P is not
engaged as the rear wheels will otherwise
be blocked.
When using the car wash function, refer to
page48, note that the parking lock P is
engaged automatically after approx. 30 min-
utes, blocking the rear wheels.
If an electrical malfunction occurs or if towing
takes longer than approx. 20 minutes, manually
release the parking lock, refer to page51.<
When towing, do not exceed a maximum
speed of 30 mph/50 km/h and a maxi-
mum distance of 30 miles/50 km, otherwise the
transmission can be damaged.<
BMW recommends transporting the vehicle on
a tow truck with a flat bed.
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
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 angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.

Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
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
Manual transmission:
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.
M dual clutch transmission:
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
If possible, do not tow-start the vehicle but
jump-start the engine, refer to page136. Vehi-cles with a catalytic converter should only be
tow-started when the engine is cold.
Manual transmission
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page46.
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.
