BMW 550i xDrive Gran Turismo 2010 - Manual (Page 150)

Anchorage points
Fold the cover outward.
Mounting
Be sure that adequate clearance is maintained
for raising and opening the glass sunroof*.
Magnetic roof-mounted luggage rack
Because of the aluminum roof, magnetic roof-
mounted luggage racks cannot be mounted.
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, refer
to page 258
.
▷ Distribute the roof load uniformly.
▷ The roof load should not be too large in area.
▷ Always load the heaviest pieces on the bot‐
tom.
▷ Fasten roof-mounted cargo correctly and
securely.
▷ Do not let objects project into the opening
path of the tailgate.
▷ Drive smoothly. Avoid sudden acceleration
and braking maneuvers. Take corners gen‐
tly.
Saving fuel
General information
Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular
maintenance, refer to
page 238, can have an influence on fuel con‐
sumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Close the windows and glass sunroof*
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire inflation
pressure, refer to page 227, at least twice a
month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
