Tire inflation pressureObserve tire approval
specificationsThe inflation pressures in the table ap-
ply to tires made by BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers. Ap-
proved tire sizes are listed on
page 128.
Your vehicle is equipped with tires that
meet US and European standards. We
recommend the exclusive use of
BMW-approved tires.BMW Tires

Fasten your safety belt at the beginning
of every trip.
To fasten: make sure you hear the lock
engage in the belt buckle.
To release: press the red button in the
buckle. Hold the belt and guide it back
into its reel.
Before using the rear safety belts,
take them out of their holder.<46cde050
For your safety, comply with the
following instructions for wearing
safety belts. If you do not, the safety
belts may not be able to provide their
maximum protection. The following in-
formation also applies to your passen-
gers: never allow more than one person
to wear a single safety belt. Never allow
infants or small children to ride in a pas-
senger's lap.
Avoid twisting the belt while routing it
firmly across your hips and shoulder.
Do not allow the belt to rest against
hard or fragile objects in your pockets.
Do not route the belt across your neck,
or run it across sharp edges and ensure
that the belt does not become caught
or jammed.
Be sure that the safety belt fits snugly
against your body at all times, and
avoid wearing clothing that prevents
the belt from fitting properly. Pull on the
belt periodically to readjust the tension
over your shoulder. In the event of a
frontal impact, a loose lap belt could
slide over your hips, leading to abdomi-
nal injury. In addition, the safety belt's
restraint effectiveness is reduced if the
belt is worn loosely. Expectant mothers
should always wear their safety belts,
taking care to position the lap belt
against the lower hips, where it will not
exert pressure against the abdominal
area.
To prevent undesired belt movements
at high speeds, leave the safety belts
for the back seat in their holders when
they are not required.<
For child restraint system installation,
refer to page 66.
For care instructions, refer to "Car care"
on page 142.
If the safety belt system has been
subjected to the stresses involved
in an accident or otherwise damaged:
Have the entire safety belt mechanism
replaced by your BMW center, including
the safety belt tensioner. In addition,
have your BMW center inspect the
safety belt anchors. If a child restraint
system was in the vehicle during an
accident, consult the manufacturer's
instructions regarding replacement.cChild restraint systems
*
Never install a rear-facing child re-
straint system in the front passen-
ger seat. If you do so, the child could
be injured in an accident when the
airbag is triggered. Do not modify the
child restraint system in any way. If you
do so, it will not provide your child with
maximum protection.<

Tire Pressure Control (RDC)
*
The conceptRDC monitors the tire pressure at all
four wheels – even while you are driv-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
In order for the system to "learn" cor-
rect tire inflation pressure, check the
pressure in all the tires, compare your
pressures with those in the tire inflation
tables (page 28), and make corrections
as necessary. Then activate the system.
This indicator lamp in the
instrument cluster informs you
whenever the tire pressure is
not normal.
Activate the system 1 Turn the ignition key to position 2
(do not start the engine)
2 Press the button long enough for
the indicator lamp in the instrument
cluster to light up yellow for a few
seconds
3 After you have driven a few minutes,
RDC imports the current tire inflation
pressures as the nominal values to be
monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.46cus013
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the
indicator lamp will come on with a
yellow lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic sig-
nal goes off.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer. Replace the wheel and flat tire.
The space-saver spare tire is pro-
vided for temporary use only in the
case of a tire failure. It does not have
RDC electronics and is not monitored.<
RDC cannot inform you of sudden
and severe tire damage caused by
external influences.<
Have the tires changed by your
BMW center.
Your BMW center is familiar with, and
has the special tools necessary, for
working on the RDC.<
System interferenceThe RDC may encounter interference
from outside equipment or devices
which use the same radio frequency.
The indicator lamp will come on with a
yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without RDC
electronics
>or if additional wheels using RDC
electronics are transported.
Please contact your BMW center for
additional information.

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear, and possibly
to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as aquaplaning
or hydroplaning. It is characterized by a
partial or complete loss of contact be-
tween the tires and the road surface.
The ultimate results are loss of steering
and braking control.
Driving through water:
Do not drive through water over the
road if it is deeper than 1 ft (30 cm), and
then only at walking speed, otherwise
the engine, electrical system and trans-
mission could be damaged.
Clothes hooks (when hardtop
* is
mounted):
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang heavy
objects on the hooks. If you do, they
could cause personal injury during
braking or evasive maneuvers.<
The catalytic converter reduces harmful
exhaust emissions. It is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.To ensure efficient, trouble-free engine
operation and to avoid potential damage:>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is
empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to jump-start the vehicle with outside
assistance
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables
disconnected.Be sure to observe the instruc-
tions above to prevent unburned
fuel from reaching the catalytic con-
verter, otherwise, the catalytic con-
verter could overheat and be damaged.
High temperatures occur in every vehi-
cle equipped with a catalytic converter.
Heat shields are installed adjacent to
some sections of the exhaust system.
Never remove these shields; do not
apply undercoating to their surfaces.
When driving, standing at idle, and
parking the vehicle, take extra care to
avoid contact between the exhaust sys-
tem and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious per-
sonal injury and property damage.<

Winter operationWinter is often accompanied by rapid
changes in weather, requiring not only
a different driving style, but also certain
preparations to the vehicle itself to en-
sure that your vehicle operates safely
and trouble free throughout the winter
months.CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. –34 7
(–37 6). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After its use, treatment with BMW lock
barrel grease is recommended.
Rubber seals and components To prevent the weather stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car care products is
available from your BMW center. both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
In this type of exceptional situation
where the snow chains are mounted,
deactivate the DSC. Refer to page 88.
Starting offWhen starting off from a full stop in
deep snow or when "rocking" the vehi-
cle to free it, it may be effective to
deactivate the DSC system for a short
period. Refer to page 88.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. On down-
hill grades or slopes, shift down to the
next lower gear at an early point. Main-
tain an adequate distance between
yourself and the vehicle ahead.
