Saving fuelVehicle equipmentThis chapter describes all standard, national
and special equipment provided in the model
series. Equipment not available in the vehicle is
therefore also described, for example the se‐
lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
General
Your vehicle contains wide-ranging technolo‐
gies for reducing consumption and emission
levels.
Fuel consumption depends on various factors.
A number of measures, such as a moderate
driving style and regular maintenance, can in‐
fluence fuel consumption and reduce burden
on environment.
Removing transported load that is not required
Extra weight increases fuel consumption.
Removing add-on parts after use
Remove auxiliary mirrors, roof racks and rear-
mounted racks after use.
Add-on parts on the vehicle interfere with its
aerodynamic performance and inflate fuel con‐
sumption.Closing windows and the
glass roof
An opened glass roof or opened window in‐
creases the drag coefficient and thus reduces
the range.
Tyres General Tyres can have differing effects on fuel con‐
sumption. For example, fuel consumption can
be affected by tyre size.
Checking tyre pressures regularly Check and, if necessary, correct tyre inflation
pressures at least twice a month and before
setting off on a longer journey.
Insufficient tyre inflation pressure enlarges the
rolling resistance and thus increases fuel con‐
sumption and tyre wear.
Setting off immediately Do not warm up the engine with the vehicle at
a standstill; it is preferable to set off straight
away, driving at moderate engine speeds.
This brings the cold engine to operating tem‐
perature as quickly as possible.
Driving with foresight
Avoid accelerating and braking unnecessarily.
Keep an appropriate distance from the preced‐
ing vehicle.
Anticipating the road situation and adopting a
smooth driving style will reduce fuel consump‐
tion.Seite 168Driving hintsSaving fuel168
Online Edition for Part no. 01 40 2 964 013 - VI/15

Avoid high engine speeds
Basic principle: driving at low engine speeds
reduces fuel consumption and wear.
Use 1st gear to drive off. As from 2nd gear, ac‐
celerate quickly. Avoid high engine speeds and
shift up quickly.
Shift into the highest possible gear when you
have reached the desired speed and drive at a
constant speed with the lowest possible en‐
gine speed.
Pay attention to the shift point indicator in the
vehicle, if fitted, see page 88.
Using overrun mode When approaching a red traffic light, take your
foot off the accelerator and allow the vehicle to
roll.
On downward stretches, take your foot off the
accelerator and allow the vehicle to roll.
The fuel supply is interrupted when coasting.
Switching off engine if
stopping for a relatively long
time
When you stop the vehicle for longer periods,
for example at traffic lights, railway crossings
or in traffic jams, switch off the engine.
Auto Start Stop function
The Auto Start Stop function of your vehicle
shuts off the engine automatically during a
stop.
If the engine is switched off and then started
again, the fuel consumption and emissions are
reduced compared with a permanently running
engine. Savings can be made just by stopping
the engine for a few seconds.
Fuel consumption also depends on other fac‐
tors, such as driving style, road condition,maintenance or environmental factors, for ex‐
ample.
Switching off functions that
are not necessary at the moment
Functions such as seat heating or heated rear
window require a great deal of energy and re‐
duce the range, especially in city traffic and
stop-and-go traffic.
Switch these functions off if they are not re‐
quired.
Having the maintenance
done
Have the vehicle serviced regularly to achieve
optimal economy and lifetime. Have mainte‐
nance carried out by a Service Partner or a
qualified specialist workshop.
Please also see the BMW Maintenance Sys‐
tem, see page 191.Seite 169Saving fuelDriving hints169

lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
Fuel quality
General Depending on the region, many filling stations
sell fuel that is adapted to the conditions in
winter or summer. Fuel that is sold in winter fa‐
cilitates cold starting, for example.
Note ATTENTION
Even fuels corresponding to the specifi‐
cations may be of low quality. Engine problems
can arise, for example poor engine starting, im‐
paired driving properties or reduced perform‐
ance. Danger of damage to property. In the
case of engine problems, use a different filling
station or refuel with a higher octane fuel from
a brand maufacturer.◀
Petrol
For optimal fuel consumption, the petrol
should be sulphur-free or as low in sulphur
content as possible.
Fuels labelled on the pump as containing metal
must not be used.ATTENTION
Even small quantities of the wrong fuel or
wrong fuel additives can damage the fuel sys‐
tem and engine. In addition, the catalytic con‐
verter will be permanently damaged. Danger of
damage to property. Do not use the following
fuel or additives with petrol engines:▷Leaded petrol.▷Metallic additives, for example manganese
or iron.
After filling the wrong fuel, do not press the
start/stop button. Contact a Service Partner or
a qualified specialist workshop.◀
You can fill up with fuels with a maximum pro‐
portion of ethanol of 10 %, in other words E10.
ATTENTION
Incorrect fuels can damage the fuel sys‐
tem and engine. Danger of damage to prop‐
erty. Do not fill with any fuels that either have a
higher ethanol content than recommended or
that contain methanol, for example M5 to
M100.◀
The engine has anti-knock control. This means
that different petrol grades can be used.
Petrol grade Super Plus, with RON 98.
Fill up this fuel so that the nominal perform‐
ance data values and consumption is achieved.
Minimum grade Super with RON 95.
ATTENTION
Fuel below the specified minimum qual‐
ity can impact the engine function or lead to
engine damage. Danger of damage to prop‐
erty. Do not refuel petrol below the specified
minimum quality.◀

Tyre pressures Information for your safety
A tyre’s condition and pressure influence the
following:▷Operating life of the tyre.▷Driving safety.▷Driving comfort.
Checking tyre pressures
WARNING
A tyre with inadequate or missing tyre in‐
flation pressure impairs driving properties, for example steering and braking. Danger of acci‐
dents. Check tyre inflation pressure regularly
and adjust as necessary, for example twice a
month or before any long journey.◀
Tyres have a natural, uniform tyre pressure
loss.
Tyres heat up when driving and with the tem‐
perature of the tyre, the tyre filling pressure in‐
creases. The tyre filling pressure data relate to
cold tyres or tyres at ambient temperature.
Only check the tyre pressure when the tyres
are cold. In other words, after driving for a max‐
imum of 2 km or if the vehicle has been parked
for at least 2 hours.
Inflating devices can display a pressure as
much as 0.1 bar too low.
With runflat indicator: reinitialise the runflat in‐
dicator after adjusting tyre pressures.
With tyre pressure monitor: reset the tyre pres‐
sure monitor after adjusting the tyre pressure
to a new value.
Tyre inflation pressures
The tyre inflation pressures for the tyre sizes
categorised by the vehicle manufacturer as
suitable for the respective vehicle type can be
found on the door pillar of the driver's door.
If the speed letter of the tyre cannot be found,
the tyre inflation pressure of the corresponding
size applies. The tyre inflation pressure data
apply to tyres at ambient temperature.
For Australia/New Zealand WARNING
The inflation pressures on the tyre label
are applicable only for tyres explicitly men‐
tioned on the label. Since inflation pressures
for tyres that may be covered by the label – by
size, speed category and load rating/load index
– but not explicitly mentioned on the label may
be different. Please obtain adequate inflation
pressures in accordance with the tyre manu‐
facturer's specifications at your tyre dealer.◀

Tyre sizes
The pressure values apply for the tyre sizes
categorised by the vehicle manufacturer as
suitable and the tyre makes recommended for
the respective vehicle type.
More information regarding wheels and tyres
can be enquired with a Service Partner or a
qualified specialist workshop.
Tyre tread
Summer tyres
The tyre tread depth should not be less than
3 mm, 0.12 in.
Below a tread depth of 3 mm, approximately
0.12 in, there is a high risk of aquaplaning.
Winter tyres The tyre tread depth should not be less than4 mm, approximately 0.16 in.
Below a tread depth of 4 mm, approximately
0.16 in, suitability for vehicle operation in win‐
ter is restricted.
Minimum tread depth
Wear indicators are distributed across the tyre
circumference and have the legally prescribed
minimum height of 1.6 mm, approximately
0.06 in.
They are identified on the tyre's side wall by
TWI, Tread Wear Indicator.
Tyre damage
General Inspect tyres frequently for damage, the pres‐
ence of foreign bodies and wear.
Notes
Vehicle behaviour that is an indication of tyre
damage or other faults:▷Unusual vibrations during the journey.▷Unusual vehicle response, such as pro‐
nounced pulling to the left or right.
Damage can be caused by, for example, run‐
ning over kerbs, road damage etc.
WARNING
Damaged tyres can lose tyre inflation
pressure, which can lead to loss of control over
the vehicle. Danger of accidents. If you get a
note about tyre damage during the journey,
immediately reduce speed and come to a halt.
Have the wheels and tyres checked. To do
this, carefully drive to the nearest Service Part‐
ner or a qualified specialist workshop. If neces‐
sary, have the vehicle towed or transported
there.◀
WARNING
Damaged tyres can lose tyre inflation
pressure, which can lead to loss of control over
the vehicle. Danger of accidents. Do not repair
damaged tyres, have them renewed instead.◀
Age of tyres
Recommendation
Irrespective of wear, change tyres after
six years at the latest.
Date of manufacture
On the tyre side wall:
DOT … 0115: the tyre was made in the
1st week of 2015.

ted speed for the tyres fitted must be dis‐
played in the driver's field of view. The sticker
is available from a Service Partner or a qualified
specialist workshop.
If winter tyres are fitted, observe and comply
with the respectively permitted maximum
speed.
Interchanging front and rear wheels
The manufacturer of your vehicle advises
against interchanging the front and rear
wheels. This could impair vehicle handling
Such a change is not permitted in vehicles with
different tyre or rim dimensions on the front
and rear axles.
Tyre storage
Store wheels and tyres in a cool, dry and pref‐
erably dark place when not in use.
Protect tyres against contamination from oil,
grease and fuel.
Do not exceed the maximum tyre pressure in‐
dicated on the tyre's side wall.
Remedying flat tyres Safety measures▷Park the vehicle on a solid surface and as
far away from moving traffic as possible.▷Switch on hazard warning lights.▷Protect the vehicle against rolling, by ap‐
plying the parking brake.▷Engage the steering wheel lock in the
straight ahead position of the wheels.▷Allow all vehicle occupants get out of the
vehicle and guide them out of the danger
area, for example behind the crash barrier.▷Set up warning triangle an appropriate dis‐
tance away.Mobility system
Principle With the mobility system, minor tyre damage
can be quickly sealed, to allow you to drive on.
To do that, liquid sealant is pumped into the
tyres which encloses the damage from the in‐ side when it hardens.
The compressor can be used to check the tyre
inflation pressure.
Notes▷Please observe the notes on the applica‐
tion of the Mobility system which are on
the compressor and the sealant container.▷Applying the Mobility system can be inef‐
fective for tyre damage as from a size of
approximately 4 mm.▷Contact a Service Partner or a qualified
specialist workshop if you are unable to put
the tyre back in operation.▷If possible, foreign matter that has penetra‐
ted the tyre should remain inside the tyre.▷Remove the speed limit sticker from the
sealant container and attach to the steer‐
ing wheel.▷Using sealants can damage the TPM wheel
electronics. If sealant is used, check the
electronics as soon as you get an opportu‐
nity and have them replaced if necessary.
DANGER
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to
penetrate the vehicle. The exhaust gas con‐
tains carbon monoxide, which is colourless and
odourless, but highly toxic. In enclosed spaces,
the exhaust fumes can also build up outside
the vehicle. Danger of fatal injury. Keep the ex‐
haust pipe clear and ensure sufficient ventila‐
tion.◀
Storage
Mobility system is located under boot floor.
