2012 BMW X3 ECU

In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the gear
in which the least braking is required. Otherwise,
the brake system may overheat, resulting in a
reduction in the brake system efficiency.
Manual transmission:
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
necessary.
Automatic transmission:
You can increase the engine's braking effect by
shifting down in the manual mode of the auto‐
matic transmission, refer to page 65.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with the engine
stopped, as doing so disables engine braking. In
addition, steering and brake assist is unavailable
with the engine stopped.◀
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked vehicle
When using the automatic climate control, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Roof-mounted luggage rack
Note
Installation only possible with roof rack.
Roof racks are available as special accessories.
Attachment to the rack
Follow the installation instructions of the roof
rack.
Mounting
Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
Loading
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle handling and steering response.
Therefore, note the following when loading and
driving:▷Do not exceed the approved roof/axle loads
and the approved gross vehicle weight.▷Distribute the roof load uniformly.▷The roof load should not be too large in area.▷Always place the heaviest pieces on the bot‐
tom.▷Secure the roof luggage firmly, e.g., tie with
ratchet straps.▷Do not let objects project into the opening
path of the tailgate.▷Drive smoothly. Avoid sudden acceleration
and braking maneuvers. Take corners gen‐
tly.Seite 130Driving tipsThings to remember when driving130

Stowing cargo▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.▷Cover sharp edges and corners.▷Do not stack cargo above the top edge of the
backrests.▷Heavy cargo: stow as far forward and as low
as possible, ideally directly behind the rear
seat.▷If necessary, fold down the rear backrests to
stow cargo.▷Use the partition net, refer to page 120, to
protect passengers. Make sure that objects
cannot penetrate the partition net.▷Place protective material around any sharp-
edged or pointed objects that could bump
against the rear window while the vehicle is
in motion.Securing cargo

Securing cargo
▷Smaller and lighter items: secure with re‐
taining straps or with a cargo net or draw
straps.▷Larger and heavy objects: secure with cargo
straps.
Cargo straps, cargo netting, retaining straps
or draw straps on the lashing eyes in the
cargo area.
Securing cargo
Always position and secure the cargo as
described above; otherwise, it can endanger the
car's occupants if sudden braking or swerving
becomes necessary.
Heavy or hard objects should not be carried
loose inside the car; otherwise, they could be
thrown around as a result of hard braking, sud‐
den swerves, etc., and endanger the occu‐
pants.◀
