the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving
conditions are unfavorable for driving at a
constant speed. Otherwise you could lose con-
trol of the vehicle and cause an accident as a
result. Unfavorable driving conditions include,
for example, winding roads, heavy traffic or a
poor road surface, e.g. snow, rain, ice or loose
material.<
Manual transmission/SMG
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
In Drive mode, the SMG acts similarly to an
automatic transmission in position D.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed in the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.

4 persons without luggage:
approx. 90 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h. In the event
of pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over to the side of the road at the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact your BMW Cen-
ter.<
Malfunction
The warning lamps come on in yel-
low. The Flat Tire Monitor has a mal-
function or has failed. Have the sys-
tem checked as soon as possible.
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 increases, i.e. the 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 more and
more. This improves the handling capability 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 page68.
Malfunction
The warning lamps come on. Active
steering is no longer operational. At
low speeds, greater steering wheel
movements are required, whereas at
higher speeds the vehicle reacts more sensi-
tively to steering wheel movements. Drive cau-
tiously and think well ahead. Have the system
checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Brake Force Display*
The brake lamps light up in two stages,
depending on how sharply you apply the
brakes.
>Normal braking:
The brake lamps and the center brake lamp
light up.
>Sharp braking:
The illuminated surface of the brake lamps
is enlarged, as long as the rear fog light is
not switched on.

Lamps
78 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 on, turn the light switch to the
automatic headlamp control position, refer to
page76.
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.
High beams/roadside parking
lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
*
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, if permitted in the country of use.
After parking the vehicle, press the lever up or
down beyond the pressure point, 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.<
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.
Depending on your vehicle's equipment ver-
sion, the fog lamps are switched off when you
activate 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.<
Instrument lighting
You can adjust the brightness of the instrument
lighting only when the parking lamps or the low
beams are switched on.
1.Lightly push button 1 up or down repeat-
edly until the appropriate symbol appears in

will find compartments beside the steering col-
umn
*, in the front doors and in the center con-
sole
*.
There are nets
* on the front-seat backrests.
Clothes hooks
There are clothes hooks on the grab handles in
the rear passenger compartment.
Items of clothing hung from the hooks
must not obstruct the driver's view. Do
not hang heavy objects from the hooks, other-
wise they could endanger the car's occupants,
e.g. in case of heavy braking or sudden swerv-
ing.<
Cup holders

center armrest.

Things to remember when driving
100 You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page48.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
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 the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
With convenient access and automatic
transmission
Insert the remote control into the ignition
switch.The engine can be switched off when the selec-
tor lever is in position N. Refer also to page27.
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 kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
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 kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150 lbs.
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available

Giving and receiving assistance
134 gaged and the car is not steerable. Jump start-
ing, refer to page132.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Switch on the hazard warning flashers, depend-
ing on local regulations.
Manual transmission
Gearshift lever in idle position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page47.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Sequential manual gearbox SMG
With the ignition switched on, engage selector
lever position N, and then switch the ignition
back off.
Towing with a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
Towing with a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
Towing with a tow truck
323i*, 325i, 330i
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
325xi, 330xi
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
