Things to remember when drivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine, 4,500 rpm and
100 mph/160 km/h.▷For diesel engine, 3,500 rpm and
93 mph/150 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake discs
and brake pads. Drive moderately during this
break-in period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking or
evasive maneuvers, passengers or other road
users may be injured or the vehicle may be dam‐
aged. In addition, exhaust fumes may enter the
passenger compartment.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the blower speed.▷Drive moderately.Seite 158Driving tipsThings to remember when driving158

Hot exhaust systemHot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. When driv‐
ing, standing at idle and while parking, take care
to avoid possible contact between the hot ex‐
haust system and any highly flammable materi‐
als such as hay, leaves, grass, etc. Such contact
could lead to a fire, and with it the risk of serious
personal injury as well as property damage.
Do not touch hot exhaust pipes; otherwise, there
is the danger of getting burned.◀
Diesel particulate filter
The diesel particulate filter collects soot parti‐
cles and burns them periodically at high tem‐
peratures.
During the cleaning time of several minutes, the
following may occur:▷Temporarily, the engine may run less
smoothly.▷Noises and a slight amount of smoke com‐
ing from the exhaust until shortly after the
engine is shut down.▷A somewhat higher engine speed is neces‐
sary to achieve the accustomed perform‐
ance.
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is advised that you do not use mobile commu‐
nication devices, e.g., mobile phones, inside the
vehicle without connecting them directly to the
external antenna. Otherwise, the vehicle elec‐
tronics and mobile communication devices can
interfere with each other. In addition, there is no
assurance that the radiation generated during
transmission will be discharged from the vehicle
interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
Driving through water
Drive though calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster than walking speed, up to 6 mph/10 km/h.
Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the elec‐
trical systems and the transmission may be
damaged.◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsiveness.
You can still avoid any obstacles with a minimum
of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.Seite 159Things to remember when drivingDriving tips159
Online Edition for Part no. 01 40 2 917 801 - II/13

Objects in the area around the pedalsNo objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved for
the vehicle and can be properly fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
Driving in wet conditions
When roads are wet or there is heavy rain, briefly
exert gentle pressure on the brake pedal every
few miles.
Ensure that this action does not endanger other
road users.
The heat generated in this process helps dry the
brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Traces of water under the vehicle like this are
normal.

Saving fuelVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment 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 cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required 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 consumption values in various
ways, for instance consumption can be influ‐
enced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire inflation
pressure at least twice a month and before start‐
ing 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.Seite 164Driving tipsSaving fuel164
Online Edition for Part no. 01 40 2 917 801 - II/13

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.
The gear shift indicator of your vehicle indicates
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 ac‐
celerator 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.
Auto Start/Stop function
The Auto Start/Stop function of your vehicle au‐
tomatically 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 re‐
duced. Savings can begin within a few seconds
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 determined
by other factors, such as driving style, road con‐
ditions, maintenance or environmental factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear win‐
dow defroster require a lot of energy and con‐
sume 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 200.
ECO PRO
The concept
ECO PRO supports a driving style that saves on
fuel consumption. For this purpose, the engine
control and comfort functions, e. g. the climate
control output, are adjusted.
In addition, context-sensitive instructions can
be displayed that assist in driving in a manner
that optimizes fuel consumption.
The extension of the range that is achieved as a
result can be displayed in the instrument cluster.

FuelVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Fuel quality
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 con‐
verter 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 stan‐
dards:
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 sys‐
tem.◀Recommended fuel quality
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
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. Addition‐
ally, problems relating to drivability, starting and
stalling, especially under certain environmental
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 number
— for a few tank fills. To avoid harmful engine
deposits, it is highly recommended to purchase
gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainte‐
nance.◀
Diesel
Low-Sulfur Diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-Low Sulfur Diesel ASTM D 975-xx.
xx: comply with the current standard in each
case.Seite 174MobilityFuel174
Online Edition for Part no. 01 40 2 917 801 - II/13

Use only Ultra-Low Sulfur Diesel.
The fraction of biodiesel in the fuel must
not exceed 5 %, referred to as B5. Do not use
gasoline. If you do fill the tank with the wrong
fuel, e.g., gasoline, do not start the engine as this
may damage the engine.◀
After adding the wrong fuel, contact your service
center or roadside assistance.
If the fuel pump nozzle does not fit in the filler
pipe of your BMW, please check to ensure that
you are refueling at a diesel fuel pump that is
equipped with a diesel fuel pump nozzle.
In the event the Ultra-Low Sulfur Diesel fuel can‐
not be fully inserted into the fuel filler neck,
please contact BMW Roadside Assistance for
instructions on how to add fuel. For more infor‐
mation on BMW Roadside Assistance, refer to
page 214.
Winter diesel
To ensure that the diesel engine remains op‐
erational in the winter, use winter diesel.
It is available at gas stations during winter
months.
The fuel filter heating system, included as a
standard feature, prevents disruption of the fuel
supply while driving.
Do not add any diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀For vehicles equipped with
BMW Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxides
in the diesel emissions from your vehicle by in‐
jecting Diesel exhaust fluid reducing agent into
the exhaust system. A chemical reaction takes
place inside the catalytic converter that mini‐
mizes nitrogen oxides.
In order to be able to start the engine as usual,
there must be sufficient Diesel exhaust fluid
present in the separate container.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the automatic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve display
This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
The Reserve display appears af‐
ter about 1,000 miles/1,600 km
before the supply is predicted to
run out.
Refill in good time
The Diesel exhaust fluid must be replen‐
ished as soon as the Reserve display appears,
otherwise the engine cannot be restarted.◀
