Hill Descent Control HDC*
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or decreasing speed
By accelerating or braking you can change this
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range using the cruise control
* lever on the
steering column.

2To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically,
the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
greater than approx. 35 mph/60 km/h.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

1Display for target speed
2HDC display
Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable due to exces-
sive brake temperature, or DSC has failed.
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.<

Giving and receiving assistance
250
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.<
With a tow truck: vehicle without xDrive
Have the BMW transported with a tow truck
with a so-called lift bar, or on a flatbed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
With a tow truck: vehicle with xDrive
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
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page247.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page55.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
With xDrive: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page87.<
