2005 BMW 645CI COUPE&CONVERTIBLE towing

Things to remember when driving
110 Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
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 minimum
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.
When the vehicle is parked
Condensation forms in the automatic air condi-
tioner system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
To prevent the exterior mirrors from being
damaged due to the width of the vehicle,
always fold them in by hand before entering an
automatic car wash.<
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 loading 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, as 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.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
800 lbs. and there will be four 150-lbs. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800 lbs. minus 600 lbs. = 200 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.

Load
The permitted load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
bulkhead behind the rear seats.
>Cover sharp edges and corners.
Securing cargo
>Use the luggage net* or securing straps to
hold down small and lightweight luggage
and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Always position and secure the load as
described above, otherwise it may
present a danger to passengers during braking
or evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page192, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of freeway safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuver.<
Pad on bottom of luggage
compartment
If required, you can use the pad e.g. to transport
dirty or soiled objects. The rubberized side is
washable and has an anti-slip effect.

Towing and tow-starting
Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Use tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page180, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as possible. Use the tow fitting
for towing only on roads. Avoid lateral strains on
the tow fitting, e.g. do not the lift vehicle by the
tow fitting.<
Access to screw thread
Rectangular cover in bumper:
Press the arrow symbol of the cover.

Rear
Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering wheel
could lock and it would be impossible to steer
the vehicle. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering. Active steering is
deactivated and larger steering wheel move-
ments 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.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage selector-
lever position N, then switch off the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
The tow fittings used should be on the same
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 strictly limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise to other vehicle parts could
result.<
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.
Secure the tow rope to the tow fitting only. Oth-
erwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page186.<
Only tow-start vehicles with a catalytic con-
verter with the engine cold. It is better to jump
start the engine, refer to page186.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
3.Shift into 3rd gear, vehicles with SMG, see
below.4.Have the vehicle tow-started with the clutch
pedal completely depressed and slowly
release the clutch. After the engine starts,
immediately depress the clutch pedal com-
pletely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Vehicles with SMG Sequential manual trans-
mission:
1.Tow-start in selector lever position N.
2.Select sequential mode. The correct gear
will be selected and engaged automatically.
