Self-leveling suspension*
Malfunction
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activi ty Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with a ppropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving co mfort may be notice-
ably reduced. Even if th e orientation of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Function requirements
In order to assure the re liable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure. The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change. <
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires. <
In the following situatio ns, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Sporty driving style: slip in the drive wheels,
high lateral acceleration
> Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, th e initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or with the
compact wheel
*. <

Things to remember when driving
144
Driving on poor roads
Your BMW is at home on all roads and surfaces.
It combines a 4-wheel drive system with the
advantages of a normal passenger car.Do not drive on unpaved terrain, as other-
wise the vehicle may be damaged. <
When you are driving on poor roads, there are a
few points which you shou ld strictly observe for
your own safety, for that of your passengers,
and for the safety of the vehicle:
> Familiarize yourself wi th the vehicle before
driving off and avoid taking risks at all costs.
> Adapt your driving spee d to the road condi-
tions. The steeper and rougher the road
surface is, the lower the speed should be.
> If you want to drive on very steep uphill or
downhill gradients, ma ke sure beforehand
that the engine oil and coolant levels are
near the MAX mark, refer to page 259.
BMW X5: you can operate your vehicle on
uphill and downhill gradients with a maxi-
mum slope of 50 %.
> On very steep downhill slopes, use Hill
Descent Control HDC, refer to page 98.
BMW X5: it is possible to start off on inclines
of up to 33 %. The permissible body roll is
50 %.
> While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenev er possible.
> Make sure that the undercarriage does not
touch the ground, for example on crests and
bumpy roads. The ground clearance of the
vehicle is a maximum of approx. 8 in/20 cm.
Please note that the ground clearance can
vary depending on lo ading and the driving
conditions of the vehicle.
> Only drive through road surface water up to
a maximum water depth of
> BMW X5 20 in/50 cm
> BMW X6 17 in/45 cm
and only drive at walking speed; do not
remain stationary. >
After driving through water at low speed,
lightly press the brake pedal several times
to dry the brakes and to prevent the braking
effect from being reduced by wetness.
> Depending on the condition of the surface,
it may be practical to briefly activate DTC,
refer to DTC Dynamic Traction Control on
page 97.
> If the drive wheels spin on one side, depress
the accelerator pedal su fficiently so that the
driving stability control systems can distrib-
ute the drive forces to the individual wheels.
Please note the following points after driving on
poor roads to maintain the driving safety of your
BMW:
> Clean the coarsest dirt from the body.
> Clean mud, snow, ice etc. from the wheels
and tires and check the tires for damage.
