Airbags1 Front airbag for driver and front
passenger
2 Side Impact Head Protection System
for driver and passenger sides (front
and rear
*)
3 Side airbags for driver and passenger
sides (front and rear
*)
Protective effectThe front airbags supplement the safety
belts by providing additional protection
for the front-seat occupants in the
event of a severe frontal impact in
which the protection afforded by the
safety belts alone may no longer be
sufÞcient. The Side Impact Head
Protection System and the side airbags
help provide protection in the event of a 530us035
side impact. Each of the side airbags is
designed to help support the upper
body.
The side airbags in the rear
passenger area
* of your vehicle
may already have been deactivated
either at the time of manufacture or by a
BMW Sports Activity Vehicle center.
You may have them activated if you
desire to do so. Please contact your
BMW Sports Activity Vehicle center for
additional information.<
For information on the correct sitting
posture, refer to page 44.
The airbags will not be triggered in
the event of a minor accident, a
vehicle roll-over, or collisions from the
rear.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not attempt to remove the
airbag restraint system from the
vehicle. In the event of a malfunction,
deactivation, or triggered actuation (as
a response to an accident) of the airbag
restraint system, consult your
BMW Sports Activity Vehicle center for
testing, repairs or service operations.
Do not modify or tamper with either the
wiring or the individual components in
the airbag system. These include the
padded steering wheel hub, the instru-
ment cluster, the side trim panels of the
front or rear doors and the roof pillars or
the sides of the headliner. Do not
remove or dismantle the steering wheel
yourself. To ensure compliance with
official safety regulations, entrust
disposal of airbag generators to a
BMW Sports Activity Vehicle center.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury. Do not touch the individual
components directly after the system
has been triggered, as otherwise there
is a danger of burns.<

Starting the engine Do not press the accelerator pedal
while starting the engine.
BMW X5 3.0i:
Do not actuate the starter for too
short a time. Do not turn it for more
than approx. 20 seconds. Release the
ignition key immediately as soon as the
engine starts.
BMW X5 4.4i, 4.6is:
Your BMW is equipped with the conve-
nience starting feature. Simply turn the
key to position 3 (starter) and then
release it immediately.
The starter actuation continues to
operate automatically for a certain
period of time and is stopped automati-
cally as soon as the engine has started.
The automatic starting mode will not
operate if the battery voltage is low.
The engine can be started by means of
jump-starting, refer to page 164.<
Do not allow the engine to warm up
by leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.
Should the engine fail to start on the
first attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
from approx. +5 7 (Ð15 6) and at alti-
tudes above 3,300 ft (1,000 meters):
>For the initial start attempt, allow the
starter to remain engaged somewhat
longer (approx. 10 seconds).
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging,
always switch off electrical devices that
are not in use. Switch the ignition off
when the vehicle is not being driven.Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to damage of the
catalytic converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable mate-
rials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
serious personal injury and property
damage.<

Dynamic Stability Control (DSC)To switch the system offPress the button; the indicator lamp
comes on and stays on.
Traction intervention remains active;
that is, braking intervention will
continue.
In the following exceptional circum-
stances, it may be effective to switch
off the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels "churn" on muddy
surfaces
>When driving with snow chains. 530de230
As a result of the traction interven-
tion, the brakes may be subjected
to additional loads when the system is
switched off. For this reason, it is
possible that the braking intervention
will be disabled automatically for a brief
period in order to limit brake tempera-
ture.
To maintain vehicle stability, always
drive with the system switched on when
possible.<
To switch the system on againPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
Do not make any modifications to the
DSC system. Service procedures on
the system are to be performed by
authorized technicians only.<
Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following instructions: Engine and axle drive Up to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 rpm and the following road
speeds during this initial period:
6-cylinder engines: 100 mph (160 km/h)
8-cylinder engines: 106 mph (170 km/h)
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles
(2,000 km), engine and vehicle speeds
can gradually be increased.
You should also comply with these
break-in procedures if the engine or
one of the axle drives is replaced later
in the course of the vehicle service life.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
For this reason, drive with extra care
during the initial 200 miles (300 km).
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads.<
Brake systemApprox. 300 miles (500 km) must
elapse before the brake pads and
rotors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and long service life later
on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not light up
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine switched off Ð
when towing, for instance Ð substan-
tially higher levels of pedal force will be
required to brake the vehicle.<

Information for your safety The factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety which depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures Ð
including the spare wheel Ð regu-
larly (refer to page 26), at least every
two weeks and before beginning a
longer trip. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately
resulting in an accident.<
Tire tread Ð Tire damage Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is 0.063 in (1.6 mm). Tread wear
indicators (arrow) are embedded in the
base of the tire's tread. Their locations
are indicated by the legend TWI Ð Tread
Wear Indicator Ð at various points on
the tire's shoulder. When the tread
reaches a depth of 0.063 in (1.6 mm),
these indicators appear to signal that
the tires have worn to the minimum
legal level. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively 390de331
moderate speeds and with only small
amounts of water on the road.
Do not drive on a deflated (flat)
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.

Tire condition Tire replacement Proceed carefully to the nearest
BMW Sports Activity Vehicle center or
professional tire center, or have the
vehicle towed in to have it, its wheels
and tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.< To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. BMW tests and approves
wheel/tire combinations.
DOT Quality GradesTread wear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades.< Tread wearThe tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1g) times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
TractionThe traction grades, from highest to
lowest, are AA, A, B, and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
aquaplaning, or peak traction charac-
teristics.<

Winter tires Snow chains
*
Choosing the right tire BMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While so-called all-season tires (M+S
designation) provide better winter trac-
tion than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW Sports
Activity Vehicle center will be glad to
assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and should thus
be replaced.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
The use of narrow-link BMW snow
chains is approved only in pairs on the
rear wheels and only with tire size
235/65 R 17. Comply with all manufac-
turer's safety precautions when
mounting the chains. Do not exceed a
maximum speed of 30 mph (50 km/h).
