2008 BMW X6 engine

Replacing components
250 2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
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. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 101 lb ft/140 Nm.<
2.Stow the defective wheel in the cargo bay.
The defective wheel cannot be stored
under the floor panel flap due to its
size.<3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be glad to advise in all matters concerning
the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page253.

First-aid kit*
Some of the articles contained in the first-aid kit
have a limited service life. Therefore, check the
expiration dates of the contents regularly and
replace the contents concerned in good time if
necessary.
The first-aid kit is located in the cargo bay.
Open left side panel, remove warning triangle.
Roadside Assistance*
The BMW Roadside Assistance offers you
assistance in the event of a breakdown around
the clock, including on weekends and public
holidays.
The phone numbers of the Roadside Assis-
tance in your home country can be found in the
Contact brochure.With BMW Assist or TeleService, you can con-
tact BMW Roadside Assistance for assistance
in the event of a breakdown directly via iDrive,
refer to page222.
Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW with
power from the battery 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 contact with electrical
components while the engine is running. Care-
fully adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible personal injuries.<
Preparation
1.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 bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
On your BMW the so-called starting-aid termi-
nal in the engine compartment acts as the bat-
tery positive terminal, also refer to the engine
compartment overview on page240. The cover
cap is marked with +.

Giving and receiving assistance
254 1.Fold open the cover of the BMW starting-
aid terminal. To do so, pull the tab.
2.Attach one end of the jumper cable plus/+
to the positive terminal of the battery or a
starting-aid terminal of the vehicle provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a start-
ing-aid terminal of the vehicle to be started.
4.Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the assisting
vehicle.
Your BMW has a special nut as body ground
or negative pole.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Starting engine
1.Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful, wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The screw-on tow-fitting must always be car-
ried in the vehicle. It can be screwed in at the
front or rear of the BMW.
It is located in the toolkit under the floor panel
flap in the cargo bay, refer to page245.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<

Being towed
Make sure that the ignition is switched on,
refer to page56, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. When the engine
is stopped, there is no power assist. This then
requires increased effort for braking and steer-
ing. Active steering is deactivated and larger
steering wheel movements are required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Before towing, manually unlock the trans-
mission lock, refer to page63; failure to
do so can result in damage to the transmis-
sion.<
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response. side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Do not tow your BMW with the front or
rear axle raised individually; otherwise,
the wheels may lock and the transfer case may
be damaged.<
Only have your BMW transported on a flat bed.
Tow-starting
The engine cannot be started by tow-starting.
Start the engine by jump starting it, refer to
page253.
Have the cause of the starting difficulties elimi-
nated.
