Technology for driving comfort and safety
92 stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle is increased, i.e. steering becomes
very direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page86.
Malfunction
The warning lamps light up and a
message is displayed on the Control
Display. Active steering is malfunc-
tioning or is temporarily deactivated.
At low speeds, greater steering wheel move-
ments are required, whereas at higher speeds
the vehicle reacts more sensitively to steering
wheel movements. The stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initialization may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding text mes-
sage appears. Have the system checked.

Things to remember when driving
122
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds but do
not exceed:
>Gasoline engine
4,500 rpm or 100 mph/160 km/h
>Diesel engine
3,500 rpm or 93 mph/150 km/h
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously 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 break-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.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect the vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
Check tire inflation pressure regularly
Check the tire inflation pressure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine warm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.

Mobility
Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and the vehicle in front of
you. A defensive and smooth driving style
keeps fuel consumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accelerate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
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.
Coasting
When approaching a red light, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
On a downhill slope, take your foot off the accel-
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engine during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestions. You achieve fuel sav-
ings even if standing time is as short as approx.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner, seat
heating or rear window defroster draw large
amounts of power and consume additional fuel.
Especially in city traffic and in stop and go driv-
ing they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at a
BMW center. Also note the BMW service sys-
tem, refer to page231.
General driving notes
Close the trunk lid/tailgate
Operate the vehicle only when the trunk
lid/tailgate and rear window are closed.
Otherwise, exhaust fumes could enter the inte-
rior of the vehicle.<
If the vehicle must be driven with the trunk lid/
tailgate open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page104.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust tail pipes.
Otherwise, there is a risk of burns.<

Observe the following when refueling
When handling fuels, follow the safety
instructions provided at filling stations;
otherwise, there is a risk of personal injury or
property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to
>Premature pump shutoff
>Reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Gasoline engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Diesel engine
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 1.7 US gallons/6.5 liters.
Fuel specifications
Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>323i, 328i/xDrive: 87
>335i/xDrive: 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.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
y o u a r e u s i n g , w e r e c o m m e n d t h a t y o u r e s p o n d
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 also result in unscheduled maintenance.<
