Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a
variety of combinations and colors.
Some lamps are checked for proper functioning
and thus come on briefly when the engine is
started or the ignition is switched on.
Explanatory text messages
Text messages at the lower edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
You can call up more information, e.g. on the
cause of a malfunction and on how to respond,
via Check Control, refer to page81.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

passenger seat, or if driver or front passenger
unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child-
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Mirrors
Exterior mirrors
The front passenger's mirror is more con-
vex than the driver's mirror. The objects
seen in the mirror are closer than they appear.
Do not gauge your distance from traffic behind
you on the basis of what you see in the mirror;
otherwise there is an increased risk of an acci-
dent.<

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control Dis-
play.
Check coolant level, refer to page225.
Energy Control*
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Engine oil temperature*

Technology for driving comfort and safety
PDC Park Distance Control*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in either
bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, oth-
erwise physical circumstances may lead to the
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds>if you remain in front of an object that has
been detected by only one of the corner
sensors
>if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. The contours
of distant objects are shown on the Control Dis-
play even before the acoustic signal sounds.
The setting is stored for the remote control cur-
rently in use.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.

Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch to position 3, refer to page96.
To avoid dazzling the drivers of oncoming vehi-
cles, Adaptive Head Light is not active when the
car is driven in reverse, and directs the light to
the front passenger's side when the vehicle is at
a standstill.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.

Roadside parking lamps, left or right*
There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for a longer
period, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Switching off
Press the lever in the opposite direction to the
pressure point, arrow 3.
Fog lamps*
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up whenever the
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high
beams.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<

Things to remember when driving
120
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 an engine speed of 4500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down 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.
