Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example. <
Children on the passenger seat
Always transport children under the age
of 13 or smaller than 5 ft/150 cm in a
child-restraint system suitable for their age,
weight and size, and with the passenger airbag
deactivated. Otherwise, there is an increased
risk of injury in the event of an accident or if the
airbags deploy. <
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restr aint system that is
appropriate for their age, size and weight.
For more information on automatic deactivation
of the passenger airbags refer to page 86.
Installing child-restraint
systems
After installing a child-restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.
Observe the child-restraint system manufac-
turer's instructions when selecting, installing
and using child-restraint systems. Otherwise
the protective effect may be diminished. <
Standard child-restraint systems are designed
to be secured with a lap be lt or with the lap-belt
section of a lap-and-shou lder belt. Incorrectly
or improperly installed child-restraint systems
can increase the risk of injury to children.
Always follow the installa tion instructions for
the system with the greatest care.
On the passenger seat
After installing a child-restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated, otherwise there is an increased
risk of injury if the airbags deploy. <
Seat position
Before installing a child-restraint system, move
the passenger seat as far back and up
* as pos-
sible to obtain the best possible position for
the belt.
Backrest width*
The backrest width of the passenger's
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise the child seat's stabil-
ity on the passenger's seat is limited. <
1. Adjust the backrest width to its widest set-
ting, refer to page 43.
2. Install the child seat.
Child seat security
The safety belt for the passenger can be locked
to prevent it from being pulled out when it is
used to secure child-restraint systems.

Lateral storage compartment behind
the seats
This space can be used to store briefcases, for
example.
When loading the rear storage shelf, do
not move both seats all the way forward
while moving them to th eir uppermost position
and leaning the backrests forward. Otherwise,
the seats could hit and damage the seal on the
windshield and the sun visor.
Only transport light and small objects in the lat-
eral storage compartment; otherwise, braking
maneuvers and swerving may lead to a safety
hazard due to objects flying about the passen-
ger compartment. Only transport heavy lug-
gage in the cargo bay if it has been appropri-
ately secured. <
Cup holders*
Use lightweight and shatterproof contain-
ers and do not transp ort hot beverages,
otherwise there is an increased risk of injury in
the event of the accident. Do not force contain-
ers that are too large in to the cup holders, oth-
erwise damage could result. <
In the center armrest
The cup holders are located the center console.
Attachable cup holder*
Attaching to the center console

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission 's kick-down mode or
Launch Control.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do no t achieve their full trac-
tion potential until afte r an initial break-in
period. Therefore, drive cautiously 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 cautiously during this break-in
period.
Clutch
The function of the clut ch reaches its optimal
level only after a distan ce driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight incr eases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.
Close both windows
An open glass roof or window causes higher air
resistance and thus increases fuel con-
sumption.
Check tire inflation pressure regularly
Check the tire inflation pr essure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine wa rm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

Before driving into a car wash
General information on caring for your BMW
can be found on page204.
With convenient access and automatic
transmission
Insert the remote control into the ignition
switch.
The engine can be switched off when the selec-
tor lever is in position N. Refer also to page 204.
With convenient access and 7-gear
sport automatic transm ission with dual
clutch
Insert the remote control into the ignition
switch.
The engine can be switched off when the trans-
mission is in position N. Refer also to page 205.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overlo ading 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
vehicle. <
When storing objects in the rear storage
shelf, do not move both seats all the way
forward while moving th em to their uppermost
position and leaning the backrests forward.
Otherwise, the seats could hit and damage the
seal on the windshield, the sun visor and the
headliner. <
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.
passengers in your ve hicle, the amount of
available cargo and lugga ge 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 tra iler will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the availa ble cargo and luggage
load capacity of your vehicle.

Things to remember when driving
114
Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the cargo bay partition,
and as low as possible.
> Cover sharp edges and corners.
Cargo, securing
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 behind
the seats for attaching the cargo straps.
Adhere to the informat ion included with the
cargo straps.
Always 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 a pproved axle loads, refer
to page 222, as excessive loads can pose a safety hazard, and may al
so place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants. <
Before opening the hardtop, fold down
the cargo bay partition. Make sure the
cargo bay is loaded correctly, otherwise parts of
the hardtop can be damaged, refer to
page 105.<

Fuel specifications
Do not fill the tank with leaded fuel as this
would cause permanent damage to the
catalytic converter.
Do not fill the tank with E85, i.e. fuel containing
85 % ethanol, nor with Fl exFuel. Otherwise, the
engine and fuel suppl y system will be dam-
aged. <
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is hi ghly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
> Z4 sDrive30i: 87
> Z4 sDrive35i: 89
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged. <
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among ga solines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranti es with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
driveability, starting and stalling problems
especially under certai n environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand such as gasoline
that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in un scheduled maintenance. <
