If the display ACC --- mph/km/h briefly
appears in the instrument cluster, it might
be that conditions necessary for operation are
not currently being met. To call up Check Con-
trol messages, refer to page79.<
Warning lamps
The display2 flashes red and a sig-
nal sounds.
The system is warning you to inter-
vene by braking or executing an
evasive maneuver. The active
cruise control cannot automatically restore the
distance to the vehicle driving ahead.
This display does not, however, relieve the
driver of the responsibility for adapting desired
speed and driving style to traffic conditions.
The display2 flashes yellow.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
actively take over.
Radar sensor
Heavy rain, dirt, snow, or ice can impair the
detection of vehicles ahead. If necessary, clean
the radar sensor under the front bumper. In
doing so, be especially careful when removing
layers of snow and ice.
If the sensor is incorrectly aligned, the active
cruise control cannot be activated.
Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
heavy rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. It will not apply the brakes or decelerate

Maximum cooling
Maximally cooled air is obtained as
quickly as possible from an outside
temperature above 327/06 and
with the engine running.
The automatic climate control changes over to
the lowest temperature and switches into the
recirculated-air mode. The maximum air quan-
tity only flows out of the vents for the upper
body. It is therefore necessary for these vents to
be open for maximum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LED off: outside air flows into the vehicle
continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Left LED on, recirculated-air mode: the
supply of outside air into the vehicle is shut
off continuously.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>engine at operating temperature
>sufficient battery voltage
>outside temperature below 777/256
The LED lights up when the function is
switched on.
With the ignition switch at radio readiness or
higher the interior temperature, the air volume
and the air distribution can be set.
Switching off automatic climate control
The air volume, the heater and the
cooling function are all switched
off.
You can restart the automatic cli-
mate control by pressing any of its buttons
except the REST button.
Ventilation
1Knurled wheels for smoothly opening and
closing air vents
2Levers for changing the airflow direction
Do not drop any foreign objects into the
vent outlets; otherwise, they could be cat-
apulted outwards and cause injuries.<

Things to remember when driving
116 steep downhill stretches. Even light but consis-
tent pedal pressure can lead to high tempera-
tures, brake wear and possibly even brake fail-
ure.<
The braking action of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, possibly as far as
first gear, refer to page63. This prevents an
excessive load on the brakes.
Do not drive with the clutch depressed, in
idle or with the engine switched off; other-
wise, there will be no engine braking action or
power-assisted braking and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
With comfort access and automatic
transmission
Insert the remote control into the ignition lock.
The engine can be switched off in the selector
lever position N. Also refer to page37.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg, otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
800 lbs. and there will be four 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800 lbs. minus 600 lbs. = 200 lbs.

Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page188.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning, even when only small amounts of water are
present on the road surface.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm.
New tires should be mounted in the interest of
safety.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
is worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed imme-
diately and have the wheels and tires
inspected immediately. To do this, carefully
drive to the nearest BMW center or a special-
ized tire dealer that works in accordance with
BMW guidelines and uses appropriately trained
personnel. Have the vehicle towed to the repair
shop if necessary. Tire damage can be
extremely dangerous to vehicle occupants and
other road users.<

Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Follow the chain manufacturer's instructions
when installing snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains installed.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page87.<

Maintenance
The BMW Maintenance
System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page77:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores this information continu-
ously in the remote control while the vehicle is
being driven. After accessing the data stored in
the remote control, your BMW Service Advisor
can suggest precisely the right array of service
procedures for your own individual vehicle.
For this reason, when you take your vehicle in
for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date in the iDrive is always
set correctly, refer to page83; otherwise,
the effectiveness of CBS Condition Based Ser-
vice is not ensured.<
