Opening and closing
34
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.<
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 page35
>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:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
Arming and disarming
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
You can open the luggage compartment lid
using the button of the remote control even
if the alarm system is armed, refer to page30.
The lid is locked and monitored again as soon
as it is closed.
Panic mode*
You can trigger the alarm system if you find
yourself in a dangerous situation:
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
>Unlock the car with the remote control, refer
to page29.
>Insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.

>The indicator lamp flashes after locking:
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. The interior motion sensor and
the tilt alarm sensor are not activated.
>The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
>If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than approx.
5 minutes: your vehicle has been disturbed
while you were away.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. to attempts to steal a wheel
or tow the vehicle.
Interior motion sensor
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must
be completely closed
*.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In duplex garages
>During transport on car-carrying trains,
boats/ships or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
again as soon as the vehicle is locked.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
Convenient access*
Convenient access enables you to enter your
vehicle without needing to hold the remote con-
trol in your hand. All you need to do is wear the
remote control close to your body, e.g. in your
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate
vicinity or in the passenger compartment.
Convenient access supports the following
functions:
>Unlocking/locking the vehicle
>Unlocking the luggage compartment lid
separately
>Starting the engine
>Convenient closure
Functional requirement
>The vehicle or the luggage compartment lid
can only be locked when the vehicle detects
that the remote control currently in use is
outside of the vehicle.
>The vehicle cannot be locked or unlocked
again until after approx. 2 seconds.
>The engine can only be started when the
vehicle detects that the remote control cur-
rently in use is inside the vehicle.
Comparison to the standard remote
control
In general, there is no difference between using
convenient access or pressing the buttons on
the remote control to carry out the functions
mentioned above. You should therefore first
familiarize yourself with the instructions on
opening and closing starting on page28.
Special features regarding the use of conve-
nient access are described below.
If you notice a brief delay while opening or
closing windows or the glass roof, the
system is checking whether a remote control is
inside the vehicle. Please repeat the opening or
closing procedure, if necessary.<

Under the hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are unfamiliar with the statutory guide-
lines, have any work on the vehicle performed
only by a BMW center or by a workshop that
work according to BMW repair procedures with
correspondingly trained personnel. If this work
is not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
Hood
Releasing
Pull the lever.
Opening
To avoid damage, make sure that the
wiper arms are against the windshield
before you open the engine compartment. Do
not open the engine hood before the engine has
cooled down, otherwise injuries may result.<
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 20 in/
50 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may
result.
If you see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

Under the hood
220 Press button 4 in the turn indicator lever repeat-
edly until the oil level display appears in the
instrument cluster.
M dual clutch transmission: the oil level
appears in the top display.<
The oil level must be between the two mark-
ings.
A new measurement is taken automatically
each time the engine is started.
Possible displays
1Oil level OK.
2Oil level is being checked.
This can take about 1 minute if the car is at
a standstill on a level surface, or about
5 minutes while the car is moving.
If engine oil was added, it can take up to
30 minutes to get an oil level reading.
3Oil level down to minimum:
Add engine oil at the next opportunity, but
no more than 1 US quart/1 liter, refer also to
Adding engine oil on page221. Add at least
0.5 US quart/0.5 liters, otherwise the oil-
level monitor will be unable to display the
new value reliably.
If the oil level is below the minimum value, add engine oil immediately to avoid engine
damage.
4Oil level is too high.
Have the vehicle checked immedi-
ately, otherwise the excess oil may
lead to engine damage.<
5A value cannot be read at this time. The
engine is not yet warm.
Quick measurement
In addition to the automatic measurement, you
can also determine the current oil level manu-
ally, e. g. after adding engine oil, but such mea-
surements are less accurate.
1.Park the vehicle with a warm engine, i.e.
after an uninterrupted drive of at least
6 miles/10 km, on a horizontal surface.
2.Let the engine idle.
3.Press the computer button in the turn indi-
cator lever repeatedly until the oil level dis-
play appears in the instrument cluster.
4.Press the computer button for at least
2seconds.
The oil level is determined. A clock symbol
appears during measurement.
5.After approx. 1 minute, the current oil level
is displayed.
Display via iDrive
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Info sources" and press the control-
ler.

Under the hood
222 cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives as these may
cause engine damage.<
Your BMW center will be glad to answer
any questions regarding BMW High Per-
formance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Approved oils belong to the 10W-60 SAE
class.<
Alternative oil types
If BMW High Performance Synthetic Oil is not
available, you can add small quantities of other
synthetic oils in between oil changes. Only use
oils with the following specifications:
>Viscosity:
preferred: SAE 10W-60;
alternative: SAE 10W-40, SAE 5W-50 or
SAE 10W-50
>Specification:
API SJ/CF, API SK/CF or higher
Low ambient temperatures
The oils used at BMW factories for your vehicle
type are suitable for virtually any ambient tem-
perature. However, if the vehicle is operated at
temperatures below –47/–206 for extended
periods, your BMW center will be glad to rec-
ommend an optimal oil.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, otherwise
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5.Turn the cap until there is an audible click.
6.If the loss of coolant is substantial, have the
cause eliminated as soon as possible.
