Saving fuel
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, refer to
page 168, can have an influence on fuel con‐
sumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following use
Remove auxiliary mirrors or rear-mounted lug‐
gage racks after use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.

Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire inflation
pressure, refer to page 155, 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 vehicle
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 en‐
gine speeds.
When you reach the desired speed, shift into the
highest applicable gear and drive with the en‐
gine speed as low as possible and at a constant
speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and coast to a halt in the highest
applicable gear.On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
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.
Fuel savings are achieved after the vehicle is
switched off for only approx. 4 seconds.
The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop. Additional information on the Automatic
Engine Start/Stop Function, refer to page 47.
Switch off any functions that are not
currently needed
Functions such as the automatic climate control
require a large amount 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 serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 168.Seite 113Things to remember when drivingDriving tips113

FuelVehicle 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 sys‐
tems.
Fuel quality
Do not use fuels that are labeled at the fuel pump
as containing metals.
Only refuel with lead-free gasoline without
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.◀
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 sys‐
tem.◀
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
Gasoline with lower AKI
However, you may also use gasoline with less
AKI.
The minimum AKI rating is: 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.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada.
Fuels containing up to and including 10 % etha‐
nol 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 warranties with respect to
defects in materials or workmanship.
Minimum fuel grade
The use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
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 result in unscheduled maintenance.◀Seite 154MobilityFuel154

Tire inflation pressure
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure, rein‐
itialize the Flat Tire Monitor, refer to page 75.
After correcting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page 78.Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your serv‐
ice center.
For correct identification of the right tire inflation
pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h, ad‐
just pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀

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.
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 65, can be displayed on the instrument
cluster.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
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/acti‐
vated-charcoal filter.

An OBD socket for testing components that are
critical to exhaust composition is located under
a cover on the driver's side.
Emissions
▷The warning lamp lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.

functions on Canadian models.
Fuel cap The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel vapor is
escaping. If the cap is then tightened, the display
should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further. In addition, if you
signed a service contract for Assist, certain ve‐
hicle data can be sent directly from the vehicle
