Winter tiresChoosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. Although all-season
M+S tires provide better winter traction
than standard summer tires with H, V,
W, Y and ZR speed ratings, they gener-
ally fail to provide the same levels of
performance as standard snow tires in
winter driving.
For of 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 on the
best winter tires for your particular driv-
ing conditions.Never exceed the maximum speed
for that the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to be-
low 0.16 in (4 mm), and should thus be
replaced.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
StorageStore tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.Snow chains
*
Use narrow-link BMW snow chains on
summer or winter tires only in pairs and
only on the rear wheels. Comply with all
manufacturer's safety precautions when
mounting the chains.

Engine oilChecking 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 all the way into the
guide tube and pull it out again
5 The oil level should be between the
two graduations on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.462de244
The space 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
To add oil Wait until the level has dropped to just
above the lower mark before adding oil.
But 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 for the
manual transmission, automatic trans-
mission, differential and the power
steering system.<462de245

Engine oil Prescribed engine oilThe quality of the engine oil is extremely
important for the function and life of an
engine. Based on extensive testing,
BMW has approved only certain kinds
of engine oil.
Use only approved "BMW High Perfor-
mance Synthetic Oil".
If you are unable to obtain "BMW High
Performance Synthetic Oil", you can
add small amounts of synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your authorized BMW center
for details concerning the specific
"BMW High Performance Synthetic Oil"
or synthetic oils that have been ap-
proved.<
You can also call BMW of North America
at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this infor-
mation.
Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
BMW recommends the use of oils in
SAE classes SAE 5W-30 or SAE 5W-40.
These oils may be used for driving in all
ambient temperatures.

Always observe all environmental
protection laws when disposing of
used oil.<
Recommendation: Have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing. Any skin areas that come in
contact with oil should be thoroughly
washed with soap and water.
Always store oil, grease, etc., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers.<

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively as
possible for you. With respect to the
previous version, maintenance costs
can clearly be reduced due to technical
innovations.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle. 462us022
Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance in-
tervals. These are then indicated in the
Service Interval Display. While conven-
tional systems rely on distance traveled
alone to determine when service is due,
the BMW Maintenance System has for
years considered the actual conditions
under that the vehicle operates, be-
cause miles can be traveled in many
different manners:
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System in-
cludes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the car
covers every kind of operating situation.
Minimal use drivers – those who drive
significantly less than 6,000 miles
(10,000 km) per year – should neverthe-
less have the oil changed at least every
two years, since engine oil ages regard-
less of the load.

same time, depending upon operating
conditions.
Have your BMW center do the
maintenance and repair.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the re-
quired special tools. In addition, check-
ing parts known from experience to be
subject to wear is a permanent part of
the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet or the Warranty and
Service Guide Booklet (Canadian mod-
els). These entries are your proof that
the vehicle has received regular mainte-
nance. They are also a prerequisite for
warranty claims.<

Washing your car Right from the start, you can wash your
new BMW in an automatic car wash.
Car wash systems that do not employ
brushes are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor:
Clean the windshield regularly. Wax
from car washes or the presence of
dead insects can cause rain sensor
malfunctions.
Switch the rain sensor off when
the vehicle passes through the car
wash (refer to page 70). Damage could
occur by an undesired actuation of the
wipers if the system is not deacti-
vated.<
Parts of the car that are inaccessible
to the automatic washer – such as door
sills, door and hood edges, etc. –
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not rub dry. Never use abrasives
or strong cleaning agents to clean the
covers
>Remove dirt and contamination
(such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water
>Always use a deicer spray to remove
accumulated ice and snow – never
use a scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture and the brake rotors
could also be corroded.<

Caring for your carExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
using special body-cavity protectants,
with the application of specially-devel-
oped and extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treatment
with a wax-based protectant is applied.
Regular maintenance makes an impor-
tant contribution to maintaining the
safety and resale 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 ongoing pro-
grams designed to further improve the
durability of their finishes. Despite this,
environmental factors that occur locally
or regionally can have negative effects
on the finish of your vehicle. These
should guide you in determining the fre-
quency 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
start extending beneath the finish, start-
ing at the point of impact.Road dirt, tar spots, dead insects, ani-
mal droppings (strong alkali concentra-
tion) and tree excretions (resins and
pollen) all contain substances capable
of causing damage when allowed to re-
main on the finish of your car 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 envi-
ronmental pollutants will damage the
car's finish unless adequate care is pro-
vided – even though this generally lim-
ited to the outside horizontal surfaces.
In coastal regions, high levels of atmo-
spheric salt and humidity promote cor-
rosion.
In tropical zones temperatures of over
1007 (406) in the shade prevail, in
addition to heavy ultraviolet radiation
and high humidity. Under those circum-
stances light colored paints reach tem-
peratures of up to 1807 (806) and
dark paints up to 2507 (1206).
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.
All of these substances cause damage
to the finish.
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.
