Roof-mounted luggage rack
*
Roof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
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 load-
ing the rack. You will find the specifica-
tions under "Technical Data" on
page 186.
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 ade-
quate clearance is maintained for rais-
ing the sliding/tilt sunroof, and that ob-
jects do not project into the opening
path of the liftgate. Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to
following traffic).
Drive smoothly. Avoid sudden accelera-
tion and braking maneuvers. Take cor-
ners gently.
The roof load increases the aerody-
namic resistance. Increased fuel con-
sumption is the immediate results.

General driving notes Catalytic converter
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
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 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.
Cargo area cover:
Do not place heavy or hard objects on
the cargo area cover. These objects
could endanger vehicle occupants dur-
ing heavy brake applications or evasive
maneuvers.
Clothes hooks:
When suspending articles of clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, 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 dam-
age 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.
>When the battery is discharged, start
the engine with an outside starting
aid.
>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 discon-
nected.

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. Otherwise, the catalytic con-
verter could respond by overheating,
leading to serious damage.
Extreme temperatures occur at the cat-
alytic converter on this and every cata-
lyst-equipped vehicle. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle, and parking the vehi-
cle, take care to avoid contact between
the exhaust system and flammable ma-
terials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
serious personal injury and property
damage.<
The concept ABS enhances active safety by helping
to prevent the wheels from locking un-
der braking. This is because: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
With ABS, you will achieve the shortest-
possible braking distances under all
given conditions (braking while driving
straight ahead or in curves, different
road surfaces).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help retain steering and maneu-
vering capability on all types of road
surfaces (asphalt, cement, dirt, wet
surfaces, snow and ice).
Braking with ABS The system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is deactivated
whenever the vehicle's speed drops
back below approx. 4 mph
(6 km/h).
To shorten the braking distance Ñ espe-
cially on steep, poor road surfaces when
driving slowly straight ahead Ñ the sys-
tem allows one or both front wheels to
lock for a short time. Nevertheless, the
vehicle still retains steering response
since this "poor road logic" is deacti-
vated again automatically as you steer.
If you are in a situation that requires full
braking, you will exploit the full beneÞts
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you

Winter tires Snow chains
*
Choosing the right tire BMW recommends special winter tires
(M+S radial tires) for driving in adverse
winter road conditions. While the All-
Season tires with M+S designation that
are mounted as standard equipment
provide better winter traction than sum-
mer tires, they generally do not achieve
the performance of winter tires.
For safe tracking and steering re-
sponse, install winter tires made by the
same manufacturer having the same
tread configuration on all four wheels.
Mount only winter tires approved by
BMW. Any BMW center will be glad to
provide you with information for select-
ing the best winter tires for your partic-
ular driving conditions.
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 pressure Once winter tires wear to a tread depth
below 0.16 in (4 mm), their performance
under winter driving conditions deterio-
rates noticeably. Worn tires should
therefore be replaced for safety consid-
erations.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires. Storage Store tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.
The use of narrow-link BMW snow
chains is approved only in pairs on the
rear wheels and only with tire size
235/65 R 17. Comply with all manufac-
turer's safety precautions when mount-
ing the chains.

Engine oil Checking 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 Push the dipstick carefully all the way
into the guide tube and pull it out
again.
5 The oil level should be in between the
two graduations on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 530us100
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine. 460de189
Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, do not wait until the oil level
drops 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 is also true for the au-
tomatic transmission, the transfer box,
the differential, and the power steering
system.< 530us101

Caring for your vehicle 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
(finish damage).
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 these stains. Re-
move tar spots with tar remover. After
cleaning, the affected areas should be
waxed to ensure continued protection.
Waxing your vehicle Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the sur-
face.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Paint damageYou can touch up small areas of dam-
age with BMW spray paint or a BMW
touchup stick.
The color code of your vehicle is pro-
vided on a tag on the right-hand panel
under the hood and on the first page of
the Service and Warranty Information
Booklet.
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. After a few days, polish
and protect the touched-in areas.
More extensive paint damage should
be professionally repaired in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with factory repair procedures.

Caring for your vehicle Window care You can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.
Clean the wiper blades with soapy wa-
ter. The wiper blades should be re-
placed twice a year, before and after
the cold season.
Use only wiper blades that have
been approved by BMW.<
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially dur-
ing the winter months. However, do not
use aggressive products containing
acids, strong alkalis or abrasives. Do
not use steam cleaners operating at
temperatures above 140 7 (60 6).
Follow the manufacturer's instructions.
If your vehicle has chrome parts
* such
as window moldings, door handles or
other items, clean these parts carefully
with ample clean water, especially if
they have an accumulation of road salt.
Use chrome polish as an additional
treatment.
Plastic components, vinyl upholstery,
headliners, lamp lenses, the clear cover
of the instrument panel and compo-
nents with a sprayed dull black surface
can be cleaned with water (add plastic
cleaner as required). Do not allow mois-
ture to soak through the seats or head-
liner. Never use solvents such as lac-
quer thinner, heavy-duty grease
remover, fuels, etc. Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied.
The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from re-
tracting the strap properly, and thus
constitute a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Please use only a damp cloth to clean
wooden fascia panels and components.
Follow up by drying with a soft cloth.
