Vehicle Memory, Key Memory How the system functions You have probably frequently wished
that you could configure individual
functions of your vehicle to reflect your
own personal requirements. In engi-
neering your vehicle, BMW has
included several user-defined func-
tions in the vehicle's design. Your
BMW Sports Activity Vehicle center can
make these settings for you.
There are vehicle and person-related
adjustments: Vehicle Memory and Key
Memory. You can configure up to four
different basic positions for four differ-
ent persons. The only requirement is
that each person uses his or her own
remote control key.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes
adjustments accordingly.
In order for you to distinguish between
the master keys with remote control,
color-coded decals are supplied
together with the keys.
What the system can doYour BMW Sports Activity Vehicle cen-
ter can provide you with details on the
capabilities of the Vehicle Memory and
Key Memory systems.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<
Following configuration of the
memory functions, vehicle opera-
tion may differ from the description in
the Owner's Manual. Should you want
to sell your BMW some day, please
remember to have the memory func-
tions reset to the default state.<
Examples for Vehicle Memory:
>Various signals that can serve as
acknowledgment for locking and
unlocking the vehicle, refer to
pages 31, 33
>Deactivating/activating the pathway
lighting function, refer to page 102.
Examples for Key Memory:
>Automatic adjustment of the driver's
seat, exterior mirror and steering
wheel with settings stored in the
memory for the individual driver when
the vehicle is unlocked, refer to
page 51
>Calling up customized settings for
the automatic climate control when
unlocking the vehicle, refer to
page 111.

Flat Tire MonitorThe concept The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure
drops significantly in relation to the
pressure another tire.
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected
and reported on the basis of a deviation
in certain speed ratios.Functional requirementTo ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
System limits
The Flat Tire Monitor cannot indi-
cate sudden severe tire damage
caused by outside factors and does not
detect a natural, even pressure drop in
all four tires.<
In the following situations, the system
could be delayed or malfunction:
>When driving on snow-covered or
slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.
Initializing system
Perform the initialization immedi-
ately every time you correct the
inflation pressure, change a tire or
change a wheel or all wheels. A drive
is required for this purpose.<
1. Start the engine, but do not drive off
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds
3. Drive off.
It takes a few minutes of driving until
the Flat Tire Monitor can detect and
indicated a flat tire.
When driving with snow chains,
do not initialize the system.<

Driving your X5 On bad roads When you are driving on bad roads,
there are a few points which you should
strictly observe — for your own safety,
for that of your passengers, and for the
safety of the vehicle:
Driving on unpaved terrain can
cause damage to the vehicle.<
>Always adapt the driving speed to the
road conditions. The rougher or
steeper the road surface is, the lower
the speed should be
>You can operate your vehicle on
uphill and downhill gradients with a
maximum slope of 50 %. If you want
to drive on uphill or downhill gradi-
ents of this kind, make sure before-
hand that the engine oil and coolant
levels are near the max mark. Refer
to pages 148 and 150.
Use the HDC Hill Descent Control on
steep downhill gradients, refer to
page 96.
It is possible to start off on gradients
of up to 32 %.
The permitted side tilt is also 50 %
>While driving, watch carefully for
obstacles such as rocks or holes. Try
to avoid these obstacles whenever
possible
>Please note that, for example on
crests and bumpy roads, the body
can make ground contact.
The ground clearance of the vehicle
is:
– 8 in/200 mm with up to four persons
– 7 in/180 mm fully loaded, without
self-leveling suspension
>Only drive through water up to a
maximum depth of 20 in/50 cm and
only at walking speed, making sure
not to stop in the process.
After leaving the water, press on the
footbrake gently several times while
driving at a low speed. The brake
applications will help to dry the
brakes, thus preventing a reduction in
braking performance caused by the
moisture.
Back onto paved road In recommending that you observe the
following points after driving on adverse
road surfaces, it is not as a beauty
treatment for your BMW. Instead, it is
intended for the maintenance of driving
safety:
>Clean the largest accumulations of
dirt from the body and check the
underbody for damage
>Clean mud, snow, ice etc. from the
wheels and tires and check the
wheels for damage
>Check to determine whether rocks,
gravel or accumulations of dirt on the
brake rotors and calipers could influ-
ence braking performance. Remove
all such foreign objects
>In order to clean the brake rotors,
apply the footbrake gently several
times while driving at a low speed.
Be sure that following traffic is not
endangered by this
>For cleaning the handbrake, apply
the lever slightly at approx. 25 mph/
40 km/h and continue to drive for
approx. 200 yards/200 meters, pro-
vided that traffic conditions allow you
to do so.
