Saving fuelVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.Tires
General information
Tires can affect fuel consumption values in
various ways, for instance fuel consumption
can be influenced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching
high engine speeds.Seite 154Driving tipsSaving fuel154
Online Edition for Part no. 01 40 2 910 796 - VI/13

When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
The gear shift indicator of your vehicle indi‐
cates the most fuel efficient gear.
Use coasting conditions
When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
On a downhill gradient, take your foot off the
accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during
longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Automatic Engine Start/Stop Function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,
road conditions, maintenance or environmental
factors.Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
consume additional fuel, especially in city and
stop-and-go traffic.
Therefore, switch off these functions if they
are not actually needed.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your
service center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 176.Seite 155Saving fuelDriving tips155

Fuel recommendation Gasoline For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Refuel only with unleaded gasoline with‐
out metallic additives.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, or permanent damage to the catalytic
converter and other components.◀
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should satisfy the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
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.◀Gasoline quality
BMW recommends AKI 93.
Minimum fuel grade
BMW recommends AKI 91.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
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.
Fuel quality
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 160MobilityFuel160

4.Insert the sealant bottle on the compressor
housing in an upright position.5.Screw the filling hose of the sealant bottle
onto the valve of the defective wheel.6.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.7.With the ignition turned on or the engine
running, switch on the compressor.
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the in‐
flation pressure may sporadically reach approx.
5 bar. Do not switch off the compressor in this
phase.
Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
If a tire pressure of 2 bar is not reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive forward and back to distribute the
sealant in the tire.4.Inflate the tire again using the compressor.
If an inflation pressure of 2 bar cannot be
reached, contact your service center.Seite 168MobilityWheels and tires168

Engine oilVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information The engine oil consumption is dependent on
the driving style and driving conditions. When
a sporty driving style is used, the engine oil
consumption, for example, is clearly higher.
Therefore, regularly check the engine oil level
after refueling.
When a dynamic driving style is used, such as
when cornering quickly, the system is unable
to measure the engine oil level. With this driv‐
ing style, measure the engine oil level using a
detailed measurement, refer to page 172.
Checking the oil level
electronically
Status display
The concept The oil level is monitored electronically during
driving and shown on the Control Display.
If the oil level reaches the minimum level, a
check control message is displayed.
Requirements
Depending on the previous displays, the status
display is displayed when the engine is running
or after the vehicle has been driven for at least
30 minutes.Displaying the oil level1."Vehicle Info"2."Vehicle status"3. "Engine oil level"
Oil level display messages
Different messages appear on the display de‐
pending on the oil level. Pay attention to these
messages.
If oil level is too low, immediately add 1 US
quart/liter of oil.
Take care not to add too much engine oil.
Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus oil can lead to engine dam‐
age.◀
Detailed measurement
The concept
In the detailed measurement the oil level is
checked and displayed via a scale.

dren and heed the warnings on the containers
to prevent health risks.◀
Oil types for refilling
Hints No oil additives
Oil additives may lead to engine dam‐
age.◀
Viscosity grades for engine oils
When selecting an engine oil, ensure that
the engine oil belongs to the viscosity grade
SAE 0W-30 or SAE 0W-40 or malfunctions or
engine damage may occur.
Alternatively, also engine oils with viscosity
grades SAE 5W-30 or SAE 5W-40 may be
used.◀
The engine oil quality is critical for the life of
the engine.
Some types of oils in some cases are not avail‐
able in all countries.
Approved oil typesSpecificationACEA A3/B4.API SK/CF or superior grade specification.
Additional information about the approved
types of oils can be requested from the service
center.
Alternative oil types If the approved engine oils are not available, up
to 1 US quart/liter of an oil with the following
specification can be added:
