Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and rear axle differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at various engine and vehicle speeds, but
do not exceed:
>Gasoline engine
4,500 rpm or 100 mph/160 km/h
>Diesel engine
3,500 rpm or 90 mph/150 km/h
Avoid full-throttle operation and use of the
transmission's kickdown mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof*/
panoramic glass sunroof*
An open glass sunroof/panoramic glass sunroof
or open windows likewise increase the drag
coefficient and therefore the fuel consumption.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine

Things to remember when driving
140 planing, and is characterized by a partial or
complete loss of contact between the tires and
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, also refer to Mini-
mum tread depth on page248.
Driving through water
Maximum water depth:
>BMW X5 20 in/50 cm
>BMW X6 17 in/45 cm
Only drive through water up to the above-
mentioned depth at no greater than walk-
ing speed; otherwise, the engine, electrical sys-
tem, and transmission can be damaged.<
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 in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page64. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise 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 automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
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 blowout.<

Care
Car-care products
For the cleaning and care of your vehicle, BMW
recommends using only products that BMW
has approved for this purpose.
Regular cleaning and care make a significant
contribution to retaining your BMW's value.
The BMW Sports Activity Vehicle Center will be
happy to consult you on products and services
for the cleaning and care of your BMW.
Genuine BMW Care Products are materi-
als tested, laboratory tested, and tested in
actual use. They offer optimum care and pro-
tection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents; they can damage your vehi-
cle.<
Cleaning agents can contain substances
that are dangerous or pose health risks.
You should therefore heed the warnings and
hazard indications on the packaging. Open the
doors or windows on your vehicle whenever
cleaning the interior. Make sure there is suffi-
cient ventilation in enclosed spaces. Use only
products that are formulated for vehicle clean-
ing.<
Exterior care
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Otherwise, signifi-
cant soiling and road salt can cause damage to
the vehicle.<
After washing the vehicle, apply the
brakes briefly to dry them. Failure to do so
may lead to a reduction in braking efficiency and
also to corrosion of the brake rotors.<
Car washes
Give preference to cloth car washes.Before driving into the car wash, make sure that
it is suitable for your BMW. Pay attention to the
following points:
>Dimensions of your vehicle, refer to
page281.
>If necessary, fold in exterior mirrors, refer to
page51.
>Maximum permissible tire width.
Avoid car washes with guide rails higher
than 4 in/10 cm as these may damage
parts of the vehicle body.<
Preparations for driving into the car wash:
>Deactivate the rain sensor to prevent
undesired wiper operation.
>BMW X5: deactivate rear window wiper and
protect it from damage. Take appropriate
protective measures; inquiring with the car
wash operator as needed.
>Remove add-on parts such as spoilers or
phone antennas if they risk being damaged.
Before driving into the car wash, observe the
following so that the vehicle is able to roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Shift into transmission position N.
3.Release the parking brake.
4.Deactivate Automatic Hold, refer to
page61.
5.Switch off the engine.
6.Leave the remote control in the ignition lock
so that the vehicle can roll.
Mixed tires*
Before driving into a car wash, make sure
that the vehicle width is not too large for
the car wash, as otherwise the vehicle and the
car wash could be damaged.<
