Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot.
Check coolant level, refer to page117.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a warn-
ing lamp comes on in the instrument cluster.
Fuel gauge
Fuel tank capacity: approx. 14 US gallons/
53 liters.
You can find information on refueling on
page104.
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.
Fuel display 135i: in speedometer.
Reserve
Once the fuel level has fallen to the reserve
zone, the indicator lamp lights up briefly and the
cruising range for the remaining amount of fuel
is displayed. The indicator lamp stays on per-
manently when the remaining range is less than
approx. 30 miles/50 km.
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.<

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. Such a Check Control mes-
sage includes indicator or warning lamps in the
instrument cluster and, in some circumstances,
a signal.

Technology for driving comfort and safety

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals warn you of
the presence of an object behind your vehi-
cle.Four ultrasonic sensors in the bumper mea-
sure the distance.
An acoustic warning does not sound until an
object is closer than approx. 2 ft/60 cm to the
corner sensors, or closer than approx. 5 ft/
1.50 m to 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. 55 yd/50 m of driving or above
approx. 20 mph/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.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 direct the
jet toward the sensors for lengthy periods and
only spray from a distance of at least 4 in/10 cm.
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 limits 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 after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously, oth-
erwise there is a risk of personal injury or prop-
erty damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.

Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page98.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed on the rear axle to enhance drive
output if the drive wheels experience a signifi-
cant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamps for
DSC in the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC is regulating the drive and braking
forces.
If the indicator lamps are on:
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:

Technology for driving comfort and safety
66 >When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
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, high 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 system while snow chains
are attached.<
