Fuel recommendationVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Gasoline For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Do not use fuels that are labeled at the fuel
pump as containing metals.
Only refuel with lead-free gasoline with‐
out metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀
Fuels with a maximum ethanol content of
10 %, i.e., E10, may be used for refueling.
The ethanol should fulfill the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: always adhere to the currently applicable
standard.
Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as
this would damage the engine and fuel supply
system.◀The engine is knock controlled. Therefore, you
can refuel with different recommended fuel
grades.
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not fill up with fuel below the speci‐
fied minimum quality; otherwise, the engine
may not run properly.◀
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.
Minimum fuel grade
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to
purchase gasoline from BP or Top Tier retail‐
ers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀Seite 226MobilityFuel recommendation226

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do
provide better winter traction than summer tires, they do not provide the same level of per‐
formance as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field
of vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
Run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Rotating wheels between axlesThe manufacturer of your vehicle advises
against swapping wheels between the front
and rear axles.
This can impair the handling characteristics.
Rotating the tires is not permissible when us‐
ing different types of tires.
Storage Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Snow chains Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your service center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufactur‐
er's instructions when mounting snow chains.
Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Do not initialize the Flat Tire Monitor if snow
chains are mounted; otherwise, the instrument
might issue an incorrect reading.Seite 235Wheels and tiresMobility235

Hood
Opening the hood Working in the engine compartment
Never attempt to perform any service or
repair operations on your vehicle without the necessary professional technical training.
If you are unfamiliar with the statutory guide‐
lines, have any work on the vehicle performed
only by a service center.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
To avoid damage, make sure that the
wiper arms are resting against the wind‐
shield before you open the engine compart‐
ment. Do not open the engine hood before the
engine has cooled down; otherwise, injuries
may result.◀1.Pull the lever.2.Push the release lever to the right and
open the hood.Danger of injury when the hood is open
There is a danger of injury from protrud‐
ing parts when the hood is open.◀
Closing the hood
Close the hood from a height of ap‐
prox. 16 in/40 cm with momentum. It must be
clearly heard to engage.
Hood open when driving
If you see any signs that the hood is not
completely closed while driving, pull over im‐
mediately and close it securely.◀
Danger of pinching
Make sure that the closing path of the
hood is clear; otherwise, injuries may result.◀
Checking the oil level General information
Engine oil consumption depends on the driv‐
ing style and the conditions of use. A highly
sporty driving style, for example, results in
considerably higher engine oil consumption.
Therefore, regularly check the engine oil level
after refueling.
The concept
The car is equipped with an electronic engine
oil level check.
When the oil quantity reaches minimum level, a
Check Control message is displayed.

MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support in maintaining road safety
and the operational reliability of the vehicle.
Service scopes and intervals may vary with the
country version. Replacement work, spare
parts, fuels and lubricants and wear materials
are calculated separately. Additional informa‐
tion can be obtained from the service center.
Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 80, can be displayed on the Control Dis‐
play.
Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control.
Your service center will read out this data and
suggest the right array of service procedures
for your vehicle.
Therefore, hand your service specialist the re‐
mote control that you used most recently.
Storage periods Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/
activated-charcoal filter.

Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions.◀
On the driver's side is an OBD socket for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning light lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.▷The warning light flashes under certain cir‐
cumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐riod can seriously damage emission con‐
trol components, in particular the catalytic
converter.

Retractable hardtop
When you open a wet hardtop, water drops
may run into the cargo area. If necessary, re‐
move items from the cargo area beforehand to
avoid water stains or soiling.
After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action
can be reduced and corrosion of the brake
discs can occur.
Fully remove any residue from the windows to
prevent obstruction of view from streaking,
wiping noises, and wiper wear.
Vehicle careCar care productsBMW recommends using cleaning and care
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are
dangerous and harmful to your health.◀
Vehicle paint Regular care contributes to driving safety and
value retention. Environmental influences in
areas with high air pollution or natural contami‐
nants, such as tree resin or pollen, can have an
impact on the vehicle paint. Tailor the fre‐
quency and extent of your car care to these in‐
fluences.
Immediately remove aggressive substances,
such as spilled fuel, oil, grease, or bird drop‐
pings, to prevent damage to or discoloration of
the paintwork.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every
two months.Seite 258MobilityCare258
Online Edition for Part no. 01 40 2 954 104 - II/15

Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care Vacuum regularly with a vacuum cleaner.
If they are very dirty, e.g., beverage stains, use
a soft sponge or microfiber cloth with a suita‐
ble interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the
material vigorously.
Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀
Caring for special components
Light-alloy wheels When cleaning the wheels on the vehicle, only
use a neutral wheel rim cleaner with a pH value
of 5 to 9. Do not use abrasive cleaners or a
steam jet hotter than 140 ℉/60 ℃; otherwise,
damage may result. Adhere to the manufac‐
turer instructions.
Aggressive, acidic, or alkaline cleaners may
destroy the protective coating of neighboring
components such as the brake disc.
Chrome surfaces
Carefully clean components such as the radia‐
tor grille or door handles with an ample supply
of water, possibly with shampoo added, partic‐
ularly when they have been exposed to road
salt.Rubber components
Aside from water, treat only with rubber
cleansers.
When cleaning rubber seals, do not use any
silicon-containing car care products in order to
avoid damage or reduced noise damping.
Fine wood partsClean fine wood facing and fine wood compo‐
nents only with a moist rag. Then dry with a
soft cloth.
Plastic components These include:▷Imitation leather surfaces.▷Headliner.▷Lamp lenses.▷Instrument cluster cover.▷Matte black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Moisten the cloth lightly with water if neces‐
sary.
Do not soak the headliner.
Do not use cleansers that contain alcohol
or solvents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead
to surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
No chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
