OBD interface socketThe interface socket for the Onboard
Diagnostic is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deteriora-
tion and malfunction.
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. 530us105
Indication of the above-
described malfunction in 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
will light up. If the filler cap is subse-
quently tightened, the indicator lamp
should extinguish within a few days.<
Event Data Recorders Your vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agree-
ment for the BMW Assist system, cer-
tain vehicle information may be trans-
mitted or recorded in order to provide
such services.

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. For this reason, follow the instruc-
tions below carefully when replacing
a bulb. If you are not familiar with any
of the procedures, consult your BMW
Sports Activity Vehicle center.
Never touch the glass on new
bulbs with your bare fingers, as
even minute amounts of contamination
will burn into the bulb's surface and
reduce its service life. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW Sports Activity Vehicle cen-
ter.
To prevent short circuits, before
working on any electrical system,
equipment or accessory you should
always switch it off and disconnect the
cable from the battery's negative termi-
nal before starting.
To avoid possible injury or equipment
damage when replacing bulbs, observe
any instructions provided by the bulb
manufacturer.<

Lamps and bulbs Changing a tire LEDs light-emitting diodes Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays 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.<

Removal aid for spare wheel By using this device, you do not have to
lift the spare wheel out of the recess by
hand.
Its task is to help you to move the wheel
onto the tailgate, from where you can
easily lift it off.
1. Close the tailgate again
2. Grasp the handle of the removal aid
behind the spare wheel with both
hands and pull upward over the tail-
gate, refer to arrow 530de310

Changing a wheel 6. Insert the support rod in the tailgate
lock and press down until it engages,
refer to arrow 1; then lock hook of
rod in striker, refer to arrow 2
Be sure that the support rod is
locked firmly in place. If you fail to
do so, the tailgate could move upward
quickly and cause personal injury and
vehicle damage.<
7. You can now release the locked tail-
gate and take the spare wheel down
from the tailgate. It is recommended
that you leave the tailgate locked into
place until you have completed the
wheel change and placed the wheel
with the defective tire into the
removal aid. 530de314
Procedure1. Read carefully and comply with the
safety precautions on page163
2. Secure the vehicle to prevent it from
rolling:
Place the wedges – chocks – behind
the wheels on the side opposite the
side you are lifting. If the vehicle is
parked on a downward slope, place
the wedges securely in front of the
wheels. If the wheel must be
changed on a surface with a more
severe slope, take additional precau-
tions to secure the vehicle from roll-
ing
3. Loosen the lug bolts 1/2-turn
4. Insert the jack handle into the jack,
refer to the illustration in the next col-
umn5. Position the jack at the jacking point
closest to the flat tire so that the jack
base is vertically below the jacking
point and the entire surface of the
head of the jack will move into the
square recess of the jacking point,
refer to the illustration detail, when
the jack is cranked
6. Jack the vehicle up until the wheel
you are changing is raised from the
ground
7. Unscrew the lug bolts and remove
the wheel
8. Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
9. Position the spare wheel. Secure the

Changing a wheel Vehicle 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 page102.
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 specified
torque. The tightening torque is
101 ft-lb/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, otherwise tire
damage could lead to accidents.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. 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 Sports 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
page171. 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.<

Jump starting When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the bat-
tery in a second vehicle. You can also
use the same method to help start
another vehicle. Use only jumper cables
with fully-insulated clamp handles.
To avoid the risk of potentially
fatal injury, always avoid all con-
tact with electrical components while
the engine is running. Carefully observe
the following instructions to avoid per-
sonal injury and/or damage to one or
both vehicles.<
Preparing1. Check whether the battery of the
other vehicle has a voltage of
12 Volts and approximately the same
capacitance in Ah. This information
can be found on the battery
2. Switch off the engine of the support
vehicle
3. Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits. To avoid personal injury from
sparks, always observe this
sequence when connecting jumper
cables.<
On your BMW the so-called jump-start
connection point in the engine com-
partment acts as the battery positive
terminal, also refer to the engine com-
partment overview on page149. The
cover cap is marked with +.
1. Fold up the cap of the BMW auxiliary
terminal for jump starting, refer to
arrow
2. Connect one terminal clamp of the
positive/+ jumper cable to the posi-
tive terminal of the battery or an aux-
iliary terminal for jump starting of the
vehicle providing starting assistance
3. Connect the second terminal clamp
of the positive/+ jumper cable to the
positive terminal of the battery or to
an auxiliary terminal for jump starting
of the vehicle to be started530de325
