2006 BMW X3 2.5I Heat control

Things to remember when driving
78
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake pads and rotors.
The full braking force will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page39. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page49.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
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 minimal
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.
Cargo 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 blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire’s resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a level of performance that all pas-
senger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm. At tread depths below 0.12 in/3 mm,
there is an increased risk of high-speed hydro-
planing, even when only small amounts of water
are present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires, make
wheels, tires and suspension parts more
susceptible to road hazard and consequential
damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires checked
immediately. Drive carefully to the nearest
BMW Sports Activity Vehicle Center or tire spe-
cialist. Have the vehicle towed to one of these
locations if necessary.
Tire damage can pose a potentially lethal safety
hazard for the vehicle's occupants and other
road users alike.<
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-
