Technology for comfort, convenience and safety
92
For better control
The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp lights up:
DTC is activated.
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
xDrive*
xDrive is the 4-wheel drive system of your
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control*
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately twice walking speed without
active intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately twice nor-
mal walking speed, approx. 7 mph/12 km/h, and
then keeps this speed constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control
*.
Activating HDC
You can activate HDC:
>with the programmable buttons on the
steering wheel, refer to page54
>using iDrive
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.
5.Change to upper field if necessary. Turn the
controller until "HDC" is selected and press
the controller.
6.Select "HDC on" and press the controller.
HDC is shown in the instrument cluster.
If the vehicle applies the brakes, a message is
displayed on the Control Display for approx.
20 seconds.
Deactivating HDC
When you use the programmable buttons on
the steering wheel or via iDrive, the HDC display
goes out.
HDC is automatically deactivated at speeds
greater than approximately 37 mph/60 km/h.
Using HDC
Manual transmission:
Use HDC in low gears and reverse gear.
Automatic transmission:
You can use HDC in every drive position.

Things to remember when driving
136 the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page229.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle in
place for a long time by riding the clutch;
use the handbrake. Otherwise greater clutch
wear will result.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system, drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
The braking effect of the engine can be further
increased by downshifting, if necessary all the
way down into first gear. This strategy helps
you avoid placing excessive loads on the brake
system. For information on downshifting in the
manual mode of the automatic transmission,
refer to page64.
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
support of the braking force 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 air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page53,
otherwise they could be damaged due to the
width of the vehicle.

under Care, starting on page239.
528xi, 535xi
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is dan-
ger of damaging chassis parts.<
Rear window wiper*
The rear window wiper can be damaged in car
washes. Take appropriate protective measures;
ask the car wash operator if necessary.
Automatic and sport automatic
transmission
Follow the instructions on page62 so that the
vehicle can roll.
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.<
Make sure that no fluids leak in the cargo
bay; otherwise the vehicle could be dam-
aged.<
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, as 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
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able 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
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.

Giving and receiving assistance
256 Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page243.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page243.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Press the arrow symbol on the cover in the
bumper.

Being towed
Make sure that the ignition is switched on,
refer to page61, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist. This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Automatic and sport automatic
transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will engage dur-
ing towing.<
Manually unlocking and locking transmission
lock, refer to page65.
Do not exceed a towing speed of mph/
70 km/h and a towing distance of
90 miles/150 km; otherwise the automatic
transmission may be damaged.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
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 offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
