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 upper 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 page 73.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
Indicator lamps without text messages
The following indicator lamps notify you that
certain functions are active:
High beams/headlamp flasher 90
Lamp flashes:
DSC or DTC is regulating the propul-
sive forces in order to maintain driving
stability 78
Parking brake set 52

Starting the engine
You can start the engine or switch on the igni-
tion when a remote control is inside the vehicle.
It is not necessary to insert a remote control into
the ignition swit ch, refer to page 50.
Switching off the engine in cars with
automatic transmission
The engine can only be switched off when the
selector lever is in position P, refer to page 52.
To switch the engine off when the selector lever
is in position N, the re mote control must be in
the ignition switch.
Before driving a vehicle with automatic
transmission in to a car wash
1.Insert the remote control into the ignition
switch.
2. Depress the brake.
3. Move the selector lever to position N.
4. Switch off the engine.
The vehicle can roll.
Malfunction
Convenient access may malfunction due to
local radio waves. If this happens, open or close
the vehicle via the buttons on the remote con-
trol or using the integr ated key. To start the
engine afterward, insert the remote control into
the ignition switch.
Warning lamps
The warning lamp in the instrument
cluster lights up when you attempt to
start the engine: the engine cannot
be started. The remote co ntrol is not inside the
vehicle or is malfunctioning. Take the remote
control with you inside the vehicle or have it
checked. If necessary, insert another remote
control into the ignition switch.
The warning lamp in the instrument
cluster lights up while the engine is
running: the remote control is no
longer inside the vehicle. After the engine is
switched off, the engine can only be restarted
within approx. 10 seconds. The indicator lamp in the instrument
cluster comes on and a message
appears on the Control Display:
replace the battery in the remote control.
Replacing the battery
The remote control for convenient access con-
tains a battery that will ne ed to be replaced from
time to time.
1. Take the integrated ke y out of the remote
control, refer to page 28.
2. Remove the cover.
3. Insert the new battery wi th the plus side fac-
ing up.
4. Press the cover on to close.
Take the old battery to a battery collec-
tion point or to your BMW center.<
Windows
To prevent injuries, watch the windows
while closing them.
Take the remote contro l with you when you
leave the car, otherwise children could operate
the electric windows and possibly injure them-
selves. <

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
Display.
Check coolant level, refer to page201.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 210 7/100 6 and approx. 300 7/
150 6.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14.5 US gallons/
55 liters.
You can find information on refueling on
page 188.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
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. <

Technology for driving comfort and safety
Park Distance Control PDC*
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
in front of
* or behind your ve hicle. 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 th e case when parking.
Avoid approaching an obje ct a t h i g h s p e e d , o t h -
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 or 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 in terval 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 f t/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
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or af ter a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage.

Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed. <
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period
of time. <
In the following situations, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Performance-oriented style of driving: slip
in the drive wheels, hi gh lateral acceleration
> Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the syst em while snow chains
are attached. <
iDrive, for operating principle refer to page 16.1.
"Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine - do not drive away.
5. Start the initializat ion using "Reset".
6. Start to drive.
The initialization is completed during the trip.
The initialization is comp leted during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1. Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page 195, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result if you continue driving. <
2. At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized. <

Things to remember when driving
110
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 4,500 rpm or a
road speed of 100 mph/160 km/h.
Do not drive with full-throttle operation, and do
not use the transmission 's kick-down mode or
Launch Control.
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 no t achieve their full trac-
tion potential until afte r 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 clut ch reaches its optimal
level only after a distan ce 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 renewe d 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 incr eases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove additional mirrors and the luggage rack
when they are no longer in use. Mounted parts
affect the vehicle's aerodynamics and increase
fuel consumption.
Close both windows
An open glass roof or window causes higher air
resistance and thus increases fuel con-
sumption.
Check tire inflation pressure regularly
Check the tire inflation pr essure 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 wa rm 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.
