Safe braking Emergency stopsYou brake most effectively when you
apply maximum pedal pressure in situa-
tions requiring it: emergency stops.
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum 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.Brake fluid level If the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest BMW
Sports Activity Vehicle center.
Here increased pressure on the brake
pedal may be required, and slight pull-
ing to the side and longer braking dis-
tances may result. Please remember to
adapt your driving style accordingly.<
Disk brakes When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations 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 dur-
ing brake applications to clean the
rotors is not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal from time
to time. 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 the brak-
ing force is then immediately available
when required.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain on the brakes and possible impairment
of the braking effect.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine switched off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no
power-assist for braking or steering
when the engine is not running.
BMW recommends having brake
inspections performed at a BMW
Sports Activity Vehicle center only. If
you do not, parts of the 4-wheel drive
system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Replacing wheels/tires Snow chains
*
The right wheels and tires
BMW recommends that you use
only wheel and tire combinations
that BMW has tested and approved for
your particular vehicle. Variations in
factors such as manufacturing toler-
ances mean that even wheels and tires
with identical official size ratings could
actually have different dimensions than
the approved units – these differences
could lead to body contact, and with it
the risk of severe accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After a flat tire, always remem-
ber to have the original wheel and tire
combination remounted on the vehicle
as soon as possible.
Special features of winter tires BMW recommends winter tires for use
in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than summer
tires, they generally fail to provide the
same levels of cold-weather perfor-
mance as winter tires.
When switching to winter tires, observe
the description under Tire condition,
page 143, and Replacing wheels/tires.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW Sports
Activity Vehicle center will be glad to
assist you with the required profes-
sional knowledge and specialized
equipment. place, protecting them against light
whenever possible. Always protect tires
against all contact with oil, grease and
fuels.
Do not exceed the maximum tire infla-
tion pressure indicated on the side wall
of the tire.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. BMW recommends only using
these approved, narrow-link snow
chains. Use is only permitted in pairs on
the rear wheels with the following tire
sizes:
X5 4.8is: 255/55 R 18
All other models: 235/65 R 17
Observe the manufacturer's instruc-
tions when installing snow chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
After mounting snow chains, do
not initialize the Flat Tire Monitor.
When you are driving with snow chains,
it can be beneficial to switch off DSC
briefly, refer to page 95.<

Brake fluidBrake fluid level
If the warning lamp lights up
or the message "CHECK
BRAKE FLUID" appears in the
Check Control: stop immedi-
ately. The brake fluid in the res-
ervoir has fallen to below the
minimum level.
Add brake fluid The brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports
Activity Vehicle center is familiar with
the specifications for factory-approved
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 139.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW Sports Activity Vehicle center.
Refer also to the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach of
children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

OBD interface socket
An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity.
Display of the previously
described malfunction on Cana-
dian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire.
When this occurs, you should reduce
speed and consult the nearest BMW
Sports Activity Vehicle center as soon
as possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is sub-
sequently tightened, the indicator lamp
should go out within a few days.<

Lamps and bulbs Changing a tire Light-emitting diodes LEDs Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and dis-
plays in your vehicle. The concept
behind their operation is related to that
employed for lasers.
Do not remove the covers, and
never stare into the unfiltered light
several hours, as irritation of the iris
could result.<
Safety precautions to observe in
the event of a flat and during all
tire changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. Switch on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse, selector lever in Park with
automatic transmission, and engage
the handbrake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for instance.
If a warning triangle or portable hazard
warning lamp is required, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. The vehi-
cle or the jack could slip to the side if
you attempt to raise the vehicle on a
soft or slippery surface such as snow,
ice, tiles, etc.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height. To avoid serious or fatal
injury: never lie under the vehicle, and
never start the engine while it is sup-
ported by the jack.<

Changing a wheel Battery 10. Screw in the remaining lug bolts.
Tighten all the bolts securely in a
diagonal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern
13. Check and correct the tire inflation
pressure at the earliest opportunity.
After mounting the spare wheel or
correcting the inflation pressure,
reinitialize the Flat Tire Monitor,
refer to page 100.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure safety, always have the lug
bolts checked with a calibrated torque
wrench as soon as possible to ensure
that they are tightened to the speci-
fied torque. The tightening torque is
101 lb-ft/140 Nm.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than Genuine
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with spare wheel
Do not exceed a speed of
130 mph/210 km/h, as otherwise
accidents may occur due to tire dam-
age.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. However, to restore the original
state, the normal wheel should be
remounted as soon as possible.<
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Battery care The battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions. Your
BMW Sport Activity Vehicle center will
be glad to advise in all matters con-
cerning the battery.Charging battery Only charge the battery in the vehicle
via the terminals in the engine compart-
ment with the engine off. For correct
connections, refer to Jump-starting on
page 171. Disposal
Following replacement, have old
batteries disposed of by your
BMW Sports Activity Vehicle center or
hand them in to a recycling center.
Maintain the battery in an upright posi-
tion for transport and storage. Always
restrain the battery to prevent it from
tipping over during transport.<

Towing and tow-starting vehicle
Do not exceed a towing speed of
30 mph/50 km/h and a towing dis-
tance of 95 miles/150 km, as otherwise
the drive train may be damaged.<
Vehicles with manual transmission:
Gearshift lever in idle position.
Vehicles with automatic transmission:
Selector lever in N.
Towing methodsIn some countries, towing with a tow
bar or rope on public roads is not per-
mitted.
Familiarize yourself with the regula-
tions on towing in the respective coun-
try.
With tow bar:
The towing vehicle may not be
lighter than the vehicle to be
towed, as otherwise handling will be
uncontrollable.<
The tow fitting of both vehicles should
be on the same side. If an angled posi-
tion of the bar cannot be avoided,
observe the following:
>The freedom of movement is
restricted during cornering
>The angled position of the tow bar
creates lateral forces.
Only secure the tow bar on the
tow fittings. Otherwise, damage
could result on other vehicle compo-
nent.<
With tow-rope:
When starting off in the towing vehicle,
make sure that the tow-rope is taut.
Use nylon ropes or nylon straps
for towing, and avoid all too sud-
den jerking movements. Only secure
tow-ropes on the tow fitting. Otherwise,
damage could result on other vehicle
component.<
With tow truck:
Do not tow the X5 with the front or
rear axle raised individually, as
otherwise the wheels may block and
the transfer case may be damaged.<
The X5 may only be transported on a
truck bed.530de403
