Opening and closing Ð from the inside Use this button to operate the central
locking system whenever the doors are
closed. The doors and luggage
compartment lid are unlocked or locked
only. The antitheft alarm system is not
activated.
If only the driver's door was
locked from the outside and you
press the button, then, when you open
the driver's door, the passenger's door,
the luggage compartment lid and the
fuel filler door will unlock as well.
The driver's door will be locked if it is
closed.<
The central locking system can be
unlocked automatically as soon as
you begin to drive if you desire. You
may also have this adjusted so that it is
specific to keys.<
To unlock and open the doors>Either unlock the doors together with
the button for the central locking
system 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 locks>Either use the central locking button
to lock all doors at once
or
>press down the individual door lock
buttons. As an added design feature
to prevent the driver from being inad-
vertently locked out of the vehicle,
the driver's door lock button will not
engage as long as the door is open.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle's keys
with you so that the vehicle can be
opened again from the outside at any
time.<

Variable pre-warning zoneThe orange pre-warning zone displays
current permissible engine speeds,
depending on the engine temperature.
As the engine temperature climbs,
some of the sectors of this pre-warning
zone will go out one after the other.
Avoid engine speeds in the early
warning zone if possible.Warning zone
Be sure to avoid engine sppeds in
the red warning zone, as other-
wise, the engine can be damaged.<
In this range the fuel supply will be
interrupted to protect the engine; the
resulting effect resembles that associ-
ated with a sudden loss of power.
The general operating temperature is
between 175 7 (80 6) and 250 7
(120 6). During performance-oriented
driving, do not exceed the maximum
temperature of 300 7 (150 6).

Fuel gauge Coolant temperature gauge Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity, refer to
page 169.
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When the ignition is turned on, the indi-
cator lamp in the fuel display will light
up briefly as a functional check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedTo check the function, the warning
lamp in the coolant temperature gauge
will light up briefly when the ignition is
turned on.
If the lamp comes on while operating
the vehicle, the engine has overheated.
Switch the engine off immediately and
allow it to cool down.
Checking coolant level, refer to
page 125.
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions.

Securing the cargo in the luggage
compartment >For small, light items, use the rubber-
lined non-skid side of the floor mat or
secure with a luggage compartment
net
* or elastic straps (refer to
page 39)
>For large, heavy pieces, see your
BMW center for load-securing
devices
*. Lashing eyes (arrow) are
provided at the inner corners of the
luggage compartment for attaching
these load-securing devices.
Read and comply with the information
enclosed with the load-securing
devices.
A special luggage system is available
as an option for your BMW. Please
observe the precautions included with
the installation instructions.Mounting pointsAccess to the mounting points:
To fold up the cover (arrow), please
use the tool which is provided with the
luggage system.Loading and driving notesBecause roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
When loading, be sure to remember not
to exceed the approved roof weight,
the approved gross vehicle weight or
the axle loads. You will find the specifi-
cations under "Technical Data" on
page 168.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first (on the bottom). Be sure that
adequate clearance is maintained for
raising the sliding/tilt sunroof, and that
objects do not project into the opening
path of the luggage compartment lid.
Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to
following traffic).
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
The luggage rack and roof luggage
increase the amount of surface
exposed to the wind: increased fuel
consumption and additional strains on
the vehicle's body result from this.

Brakes: do not drive with your foot
resting on the brake pedal. Even
light but consistent pedal pressure can
lead to high temperatures, brake wear
and possibly even 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
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water:
Do not drive through water on the road
if it is deeper than 1 foot (30 cm), and
then only at walking speed. Otherwise,
the vehicle's engine, the electrical
systems and the transmission may be
damaged.
Rear window shelf:
Never use it to store heavy or hard
objects, otherwise, occupants could be
injured if the vehicle is braked hard.<
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 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 start the vehicle with an outside
starting aid
>Avoid other situations in which the
fuel is not burned or burns incom-
pletely such as frequent or extended
starter engagement 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
converter. Otherwise there is danger of
overheating and damage to the cata-
lytic converter.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle or when parking, take
precautions to avoid contact between
the hot exhaust system and easily flam-
mable materials (grass, hay or leaves,
for example). Such contact could lead
to a fire, resulting in personal injury and
property damage.<

Wheel and tire combinations The right choice Use only wheels and tires approved by
BMW for the corresponding vehicle
model, as otherwise the tires may make
contact with the body as the result of
tolerances despite the same nominal
size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to page 116.
The correct wheel-tire combina-
tion affects different systems that
otherwise will not function properly,
e.g. ABS, DSC.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel-tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheels The code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the
approved maximum speed for the tire.
Summer tires:
S = up to112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 187 mph (300 km/h)
ZR= over 150 mph (240 km/h) e.g.
Nominal width
in mm
Aspect
ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
225/45 R
1892W
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes on light-alloy wheels:
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valves frequently leads to slow
leaks. Storage Store tires in a cool, dry place,
protecting them against light when-
ever possible. Protect the tires against
contact with oil, grease and fuel. e.g.

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
dipstick 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 quantity between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter).
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.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the differential,
and the power steering system.<
Recommendation: have the oil changed
by your BMW center only.

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
vehicle finishes have led paint and
vehicle manufacturers to initiate
programs designed to further improve
the durability of their finishes. Despite
this, regional environmental factors can
have negative effects on your vehicle's
finish. These should guide you in deter-
mining the frequency and extent of your
efforts to maintain the vehicle finish.
Depending upon material and type of
impact (perforation of paint layer),
physical stresses from sand, road salt,
gravel etc., can cause corrosion to
extend beneath the finish, starting at
the point of impact.Road dirt, tar spots, dead insects,
animal 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 period of time (spots, etching,
flaking, separation in the top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other
environmental pollutants will damage
the vehicle's finish unless adequate
care is provided Ð even though this
is generally limited to the outside hori-
zontal surfaces.
In coastal regions, high levels of
atmospheric salt and humidity promote
corrosion.
In tropical zones, high humidity and
heavy ultraviolet radiation prevail, in
addition to temperatures of over 105 7
(+40 6) in the shade. Under these
conditions, light paints can reach tem-
peratures up to 175 7 (+80 6) and
dark ones up to 250 7 (+120 6).
Caring for the vehicle finish Regular washing is a preventive
measure against long-term effects from
substances that are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels
of air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive
substances. Failure to do so can lead to
changes in the paint's chemical
structure or to discoloration. Gasoline
spilled during refueling, oil, grease and
brake fluid should always be cleaned
away immediately, as should bird
droppings (finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use
cleaning 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 that you can obtain at
your BMW center.<
