Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kick down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof
An open glass sunroof or open windows like-
wise increase the drag coefficient and therefore
the fuel consumption.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The condition for the most accurate indication
of the oil level possible is measurement with the
engine at operating temperature, i.e., following
an uninterrupted drive of at least 6 miles/10 km.
You can display the oil level on the Control Dis-
play while driving or when stopped on a level
surface with the engine running.
iDrive, for operating principle refer to page16.1."Vehicle Info"
2."Vehicle status"
3."Engine oil level"
Possible messages
>"Engine oil level OK"
>"Measurement not possible at this time."

>"Measuring engine oil level...":
This can take about 3 minutes if the car is at
a standstill on a level surface and the engine
is running, and about 5 minutes while the
car is moving.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
>"Engine oil level below minimum. Add 1
quart!":
Add a maximum of 1 literUS quart/liter of
engine oil at the next opportunity, refer also
to Adding engine oil below. If the oil level
displayed is below minimum, add engine oil
immediately. Failure to do so may lead to
engine damage.
>"Engine oil level too high! Have this
checked.":
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to Service requirements on page77. Have
the system checked as soon as possible.
Adding engine oil
1 US quart/1 liter of engine oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged. caused cancer in laboratory testing.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease, etc., out of reach of children
and observe the warnings on the containers to
prevent health risks.<
Oil change
Have oil changed only at your BMW center or
at a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives, as these may
result in engine damage.<
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Only
use oils of the specification API SM or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE
classes.<

Under the hood
214 These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is composed of equal parts water and a
coolant additive. Not all commercially available
additives are suitable for your BMW. Ask your
BMW center for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the hood until the engine has
cooled down.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent 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.Have the reason for the coolant loss elimi-
nated as soon as possible.

BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The ultimate objective is to
ensure economical maintenance by providing
the ideal service for your vehicle.
Should the day come when you decide to sell
your BMW, a complete center service history
will prove to be an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page77:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores the information required
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page79, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<

Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Exhaust-gas values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the vehicle
checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain condi-
tions. This is a sign of excessive misfiring of the
engine. In this case you should reduce speed
and drive to the nearest BMW center as soon as
possible. Heavy engine misfiring causes seri-
ous damage to the emission-relevant compo-
nents, especially the catalytic converter, within
a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can be transmitted or recorded to enable corre-
sponding services.

Replacing components
222 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.
Only replace bulbs when cool, as other-
wise you may be burned.<
Whenever you perform any work on the
electrical system, turn off the systems/
consumers involved to prevent short circuits
from occurring. To avoid possible injury or
equipment damage when replacing bulbs,
observe any instructions provided by the bulb
manufacturer.<
For information on how to care for the head-
lamps, please follow the instructions on
page217.
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.<

3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with 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
page89, or reset the Tire Pressure Monitor,
refer to page90.
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. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
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 switched off. Connections, refer to
Jump starting on page232.
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 restrain
the battery to prevent it from tipping over during
transport.<
Power failure
Following a temporary power failure, e.g., due to
a discharged battery, the use of some equip-
ment will be restricted, requiring its reinitializa-
tion. In the same way, individual settings are lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page46.
>Time and date
Must be updated again, refer to page78.
>Radio
In some cases, radio stations may have to
be stored again, refer to page156.
>Navigation system
You must wait until the system becomes
functional again, refer to page132.
>Glass roof, electric
It may only be possible to raise the glass
roof. The system must be initialized, refer to
page40.
>Panorama glass roof
It may only be possible to raise the glass
roof. The system must be reinitialized, refer
to page41.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page92.
>xDrive
The system automatically initializes itself
during a trip. Indicator lamps light up during
this time. If the lamps do not disappear dur-
ing the current trip, have the system
checked.
>Power windows
The pinch prevention system for the power
windows must be reinitialized, refer to
page38.
