Opening and closing – from inside Use this button to operate the central
locking system when the doors are
closed. The doors and luggage compart-
ment lid are unlocked or locked only. The
anti-theft alarm system is not activated.
If only the driver's door was un-
locked from the outside and you
press the button, then, while the driver's
door remains open, all the other doors,
the luggage compartment lid, fuel filler
door and the glove compartment will
open as well.
It the driver's door is closed, it will be
locked.<
The central locking system can be
locked automatically as soon as
you begin to drive if you desire. You may
also have this adjusted so that it is key-
specific.<460us007
To unlock and open the doors>Either unlock the doors together with
the button for the central locking sys-
tem and then pull each of the release
handles above the armrests or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
To engage the locks>Either use the central locking button
to lock both doors, or
>press the individual safety lock but-
tons down. As an added design fea-
ture to prevent the driver from being
inadvertently locked out of the vehi-
cle, the driver's door safety lock but-
ton will not engage as long as the
door is open.
Children might be able to lock the
doors from the inside. For this rea-
son, take the vehicle's keys with you so
that the vehicle can be opened again
from the outside at any time.<

Service Interval Display
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Once the indicator lamp stays on con-
tinuously, there are still approx. 2.1 gal-
lons (8 liters) of fuel left in the fuel tank.
For fuel tank capacity, refer to page 185.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for exam-
ple), there may be slight fluctuations of
the needle.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020
BlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to con-
firm that the system is operational.
If the lamp comes on while operating
the vehicle the engine is overheated.
Shut off the engine immediately and
allow it to cool down.Between the blue and red zonesNormal operating range. It is not un-
usual for the needle to go as far as the
edge of the red zone in response to
high outside temperatures or severe
operating conditions.Checking coolant level, refer to page 13 5.460de082
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the remaining distance
before scheduled service.
The computer bases its calculations of
the remaining distance on the rate of
fuel consumption in the period immedi-
ately preceding your data request.
A flashing display and a "–" in front of
the number indicate that service inter-
val has already been exceeded by the
distance shown in the display. Please
contact your BMW center for an
appointment.46cus006

Mode selectionFrom ignition key position 1 and up, you
can call up information from the on-
board computer shown in the display of
the instrument cluster using the button
in the turn signal lever. By pressing the
button briefly in the direction of the
steering column, you can call up a new
function for display.
The displays appear in the following
order:
Time, outside temperature, average fuel
consumption, cruising range, average
vehicle speed.
Starting with ignition key position 1, the
last active setting is displayed.46cde096
Outside temperature You can change the units of measure-
ment (6/7) for the outside tempera-
ture display by pressing the right-hand
reset button in the instrument cluster
when the temperature display is active. 46cus008
Ice warning If the outside temperature drops to
approx. 37.5 7 (+3 6), the onboard
computer automatically switches to the
outside temperature display. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
The warning is repeated whenever the
temperature climbs to at least 43 7
(+6 6) following the last warning and
then drops back to 37.5 7 (+3 6).
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.<

Luggage rack for the hardtop
*
Mounting pointsAccess to the mounting points:
To open the covers (arrow), please
use the tool included with the luggage
rack system.
A special roof-rack system is available
for your BMW as an optional extra.
Please observe the precautions in-
cluded with the installation instructions.
Because roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
You will find the specifications under
"Technical Data" on page 184.46cde097
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Make sure nothing projects
into the luggage compartment lid's
opening and closing path.
Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to fol-
lowing traffic).
Drive smoothly and avoid sudden ac-
celeration or braking. Do not corner at
high speeds.
The roof load increases aerodynamic
resistance, resulting in increased fuel
consumption and additional stresses on
the vehicle body.

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.<

Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which winter tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to a tread depth
below 0.16 in (4 mm), winter tires dis-
play a perceptible decrease in their
ability to cope with winter driving condi-
tions, and should be replaced in the
interest of safety.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. Although all-season
tires with the M+S identification provide
better winter traction than summer tires
with H, V, W Y and ZR speed ratings,
they generally fail to provide the same
levels of performance as standard
winter tires.
In the interests of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels.
Mount only winter tires which have
been approved by BMW. Any BMW
center will be glad to provide you with
information on the best winter tires for
your particular driving conditions.
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.Snow chains
*
The use of narrow-link BMW snow
chains on summer or winter tires is
approved only in pairs and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when mount-
ing the chains.

Engine oilChecking the oil level 1 Park the vehicle on a level surface
2 Shut 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.462de244
When the oil is between the two
marks on the dipstick, there is approx.
1.1 US quarts (1 liter). Do not fill be-
yond the upper mark on the dipstick.
Excess oil will damage the engine.460de189
To add oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
the lower mark.
BMW engines are designed to op-
erate without oil additives; the use
of additives could lead to damage in
some cases. This also applies to the
manual transmission, the automatic
transmission
*, the differential, and
power steering system.<

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
with special body-cavity protectants,
by applying specially developed and
extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treat-
ment with a wax-based protectant is
applied. Regular maintenance makes
an important contribution to maintaining
the safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on vehi-
cle finishes have led paint and vehicle
manufacturers to initiate programs de-
signed to further improve the durability
of their finishes. Despite this, environ-
mental factors that occur locally or re-
gionally can have negative effects on
the finish of your vehicle. Use the fac-
tors to determine the frequency and
extent of your efforts to maintain the
vehicle finish.
Depending upon material and type of
impact (perforation of paint layer), phys-
ical stresses from sand, road salt, gravel, etc., can cause corrosion to
start extending beneath the finish, start-
ing at the point of impact.
Road dirt, tar spots, dead insects, ani-
mal droppings (strong alkali effect) and
tree excretions (resins and pollen) all
contain substances capable of causing
damage when allowed to remain on the
finish of your vehicle for any extended
period of time. This includes spots,
etching, flaking, and separations in the
top coat.
In industrial areas, flue dust deposits,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the
vehicle's finish unless adequate care is
provided – even though this is generally
limited to the outside horizontal sur-
faces.
In coastal regions, high levels of atmo-
spheric salt and humidity promote
corrosion.
In tropical zones, temperatures of over
105 7 (+40 6) in the shade prevail, in
addition to heavy ultraviolet radiation
and high humidity. Under these condi-
tions, light paints can reach tempera-
tures up to 175 7 (+80 6) and dark
paints up to 250 7 (+120 6).
Caring for the vehicle finish Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or aggressive natural sub-
stances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease and brake
fluid should always be cleaned away
immediately, as should bird droppings.
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol with a clean cloth or
cotton pad to remove. Remove tar
spots with tar remover. After cleaning,
the affected areas should be waxed to
ensure continued protection.
Use the cleaning and car-care
products available at your BMW
center.<
