For your own safety Warranty
Your vehicle is technically configured for the
operating conditions and registration require‐
ments applying in the country of first delivery -
homologation. If your vehicle is to be operated
in a different country it might be necessary to
adapt your vehicle to potentially differing oper‐
ating conditions and permit requirements. If
your vehicle does not comply with the homolo‐
gation requirements in a certain country you
cannot lodge warranty claims for your vehicle
there. Further information can be obtained
from your Service Centre.
Maintenance and repairs Advanced technology, e.g., the use of modern
materials and high-performance electronics,
requires suitable maintenance and repair
methods.
Therefore, have this work performed only by a
BMW center or a workshop that works accord‐
ing to BMW repair procedures with appropri‐
ately trained personnel.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.
Parts and accessories
BMW recommends using parts and accesso‐
ries approved by BMW for this purpose.Your BMW center is the right contact for genu‐
ine BMW parts and accessories, other prod‐
ucts approved by BMW and related qualified
advice.
BMW has tested these products for safety and
suitability in relation to BMW vehicles.
BMW can assume responsibility for them.
However, we cannot assume any responsibility
whatsoever for parts and accessories that have
not been specifically approved by BMW.
BMW cannot evaluate whether each individual
product from another manufacturer can be
used with BMW vehicles without presenting a
safety hazard. This guarantee is also not appli‐
cable when country-specific government ap‐
proval has been granted. Testing of this kind
may fail to embrace the entire range of poten‐
tial operating conditions to which components
might be exposed on BMW vehicles. Such
products could conceivably fail to comply with
BMW's own stringent quality standards.

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, 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.
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
traction potential until after an initial breaking-
in period.
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
observed 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 and
evasive maneuvers, passengers and other road
users may be injured, and the vehicle may be
damaged. In addition, exhaust fumes may en‐
ter 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 162Driving tipsThings to remember when driving162

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. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
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 com‐
munication devices, e.g., mobile phones, in‐
side the vehicle without connecting them di‐
rectly to the external antenna. Otherwise, the
vehicle electronics and mobile communication
devices can interfere with each other. In addi‐
tion, there is no assurance that the radiation
generated during transmission will be dis‐
charged 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 Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Drive through calm water only and 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.
Braking safely Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. 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 163Things to remember when drivingDriving tips163

Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
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.
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 serv‐
ice 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
cannot 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 216.
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.◀
BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid reducing agent into the exhaust
system. A chemical reaction takes place inside
the catalytic converter that minimizes nitrogen
oxides.
The vehicle has a tank that can be refilled.
To be able to start the engine as usual, there
must be an adequate reducing agent.
Reducing agent is added by the service center.
Warming up the systemIn 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 is shown
starting at a remaining range of
approx. 1,000 miles/1,600 km.

Refill in good time
The reducing agent must be replenished
as soon as the Reserve display appears, other‐
wise the engine cannot be restarted.◀
Diesel exhaust fluid on minimum The engine will continue to runeven when the display shows --,
as long as it is not switched off
and all other operating condi‐
tions are satisfied, sufficient fuel
for example.
Engine does not start
Do not continue driving to the limit of the
remaining travel distance. Otherwise, you will
not be able to restart the engine after switch‐
ing it off.◀
Misfueling A Check Control message is displayed when
an incorrect fluid is added.
After adding the wrong fluid, contact your
service center.
System defect
A Check Control message is displayed when
there is a system defect.
Have the diesel exhaust fluid
replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, for example, if the vehicle is driven in
a particularly sporty style or if it is driven at
high altitudes.
The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible
that the reducing agent may also need to be
replenished between regular maintenance ap‐
pointments if it is exposed to temperatures un‐
der + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before starting to drive.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃ the fill
level in some cases cannot be measured.
After adding reducing agent, the reserve dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid
When working with reducing agent in
closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may escape.◀
Keeping Diesel exhaust fluid out of reach
of children
