tow BMW M3 COUPE 2003 E46 User Guide

106Special operating instructions
Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following suggestions.
Because of its engineering design,
the BMW M3 is an especially high-
quality vehicle. It is in your best interest
to follow the break-in tips very closely.
Doing this, you will create the basis for
a long, optimum service life.<Engine and differential>Up to 1,250 miles/2,000 km: drive at
varying engine and road speeds, but
do not exceed the following engine or
road speeds:
5,500 rpm or 105 mph / 170 km/h.
Obey your local and state maximum
speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Vehicles with SMG II, refer to page 65:
refrain from using driving program 6 in
the sequential mode during the break-
in period.
>Following the break-in inspection at
1,250 miles/2,000 km, you can grad-
ually increase engine or road speeds.
Follow the same break-in procedure if
either the engine or the differential
should have to be replaced in the
future.TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus 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 hydroplaning, and can
lead to partial or complete loss of trac-
tion, as well as loss of 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 traf-
fic signal, for instance – use caution to
avoid posing a danger to other road
users.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is set.
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 off – when tow-
ing, for example – substantially higher
levels of pedal force will be required to
brake the vehicle.<ClutchThe clutch will also begin to function
optimally after about 300 miles/500 km.
Drive cautiously during this break-in
period and do not press the clutch or
shift at high engine speeds.

ceed carefully to the nearest BMW cen-
ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage, up to and including blow-
outs, can endanger the lives of both the
vehicle occupants and other road
users.<
Tire replacementDOT quality gradesTreadwear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.<Tread wearThe treadwear 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 – 1 1/2 – times
as well on the government course as a
tire graded 100. The relative perfor-
mance of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the norm
due to variations in driving habits, ser-
vice practices and differences in road
characteristics 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,
hydroplaning, or peak traction charac-
teristics.<TemperatureThe temperature grades are A – the
highest – B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.

Washer fluidsHeadlamp* and windshield
washer systemCapacity approx.
5.6 US quarts/5.3 liters.
Fill with water and – if required – with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in their
original containers. Store them inacces-
sible to children. Comply with the
instructions on the containers.<
Engine oilChecking the oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.4 US quarts/1.3 liter.

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic; switch on the haz-
ard warning flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock. Shift into 1st or Reverse and
engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area – behind a guardrail,
for instance.
If necessary, set up your warning trian-
gle or portable hazard warning lamp on
the roadside at an appropriate distance
from the rear of the vehicle.
Comply with all safety guidelines and
regulations.<
M Mobility systemYou will find an M Mobility system in the
BMW M3 for repairing flat tires. With
this system you can apply a sealing liq-
uid to the inside of the tire that seals off
the damaged point and then continue
driving.
The M Mobility system makes trans-
porting a spare wheel superfluous,
thereby reducing the amount of weight
you have to carry around.
Using the M Mobility systemTo repair a flat tire using the M Mobility
system, proceed as follows:
>Preparing the M Mobility system for
use, refer to the next column
>This is part of the M Mobility system,
refer to page 134
>Filling with sealant, refer to page 135
>Distributing sealant, refer to
page 135
>Inflating tire to correct pressure, refer
to page 136.

Filling with sealant1. Take off the round cover and take out
hose 4. Unscrew the valve dust cap
from the defective wheel and screw
the hose to the valve. Keep the dust
cap in a safe place
2. Flip open the cover and pull out the
enclosed protective gloves. Take out
hose 2 with the manometer and
screw it to the terminal for the seal-
ant container as shown in the illustra-
tion
3. Make sure that the system has been
switched off, position 0.
Take out plug 6 and insert it into the
cigarette lighter socket in the pas-
senger compartment – refer to
page 98
4. Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility sys-
tem, position I, refer to illustration,
and allow minutes to elapse, to let
the sealant flow in. It does not matter
afterward, what the tire's inflation
pressure is
5. Turn the system off.
Disconnect the connector hose from
the sealant container and the wheel
valve. Stow the M Mobility system in
the luggage compartment.Distributing the sealantRight afterward, drive at least
1 1/4 miles/2 km, so that the liquid
sealant distributes evenly throughout
the inside of the tire.

Do not exceed a maximum speed
of 40 mph / 60 km/h.
If possible, keep the vehicle speed
above 10 mph / 20 km/h. Stop in a suit-
able spot.<
Inflating tire to correct pressure1. Take out the hose with the pressure
gauge and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the pas-
senger compartment
2. Reset the air pressure to 29 psi/
200 kilopascal, and:
>Increase tire pressure: switch on
the M Mobility System, position I.
Switch off the unit briefly to check
the current tire pressure
>Decrease tire pressure: turn the
screw on the back of the manome-
ter. A valve located there will open
Even if the tire fails to hold the
pressure, you should still carry out
Step 3 before proceeding to drive the
vehicle again, refer to Distributing the
sealant for more information. Then
repeat Steps 1 through 3.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 3/16 in /
4 mm. Please consult the nearest BMW
center if the tire cannot be temporarily
repaired with the M Mobility system.<
3. Unscrew the hose from the valve and
stow the M Mobility system in the
luggage compartment. Screw the
dust cap onto the valve again.
Do not exceed the maximum
speed limit described below, oth-
erwise it could lead to accidents.<
When you start driving again, do not
exceed the permissible maximum
speed of 45 mph / 80 km/h.

Towing the vehicleTowing eyeletThe towing eyelet, which can be
unscrewed, is in the luggage compart-
ment under the floor mat and must
remain in the vehicle. This eyelet is
designed for installation in the tow
sockets located at the front and rear of
the vehicle. It is intended for towing on
paved road surfaces only.
The towing eyelet should not be used
to pull a vehicle out of deep snow, mud,
sand, etc.
Comply with all applicable towing laws
and regulations at all times.
Access to tow socketsFront:
Press out the cover panel with a screw-
driver at the top of the recess.
Rear:
Press out the cover panel with a screw-
driver at the top of the recess.
Make sure the towing eyelet is
firmly screwed all the way in, oth-
erwise the thread could be damaged.
Only use the towing eyelet provided in
the vehicle to avoid damage.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do, the compo-
nents could be damaged, possibly
leading to accidents.<
Keep the vehicles in line and avoid
towing at an offset angle. Ensure
that the tow rope connecting the two
vehicles is tight, with no slack, before
starting off.<

Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it will not be pos-
sible to control vehicle handling.<Tow-startingFor instructions on jump-starting, refer
to page 139.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.Towing a vehicle1. Gearshift lever in Neutral
2. Towing speed:
max. 45 mph / 70 km/h
3. Towing distance:
max. 95 miles/150 km
4. Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nal indicators, horn and windshield
wipers remain operative, and to pre-
vent the steering lock detent from
engaging
5. Switch on the hazard warning system
– observe applicable legal regula-
tions.
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to pre-
vent the steering lock from engaging.
The steering and brakes are without
power-assist when the engine is off.
This means that increased effort is
required for steering and braking.<

SMG II:
To push or tow, engage selector lever
in position 0.
Never work on the vehicle with a
driving position engaged.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use wheel lift or flatbed equipment
>Please comply with applicable state
towing laws.
Never allow passengers to ride in
a towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, possibly lead-
ing to accidents.<
