Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot.
In addition, a message will appear on the Con-
trol Display.
Check coolant level, refer to page206.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14 US gallons/
53 liters.
You can find information on refueling on

If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Fuel display 135i: in speedometer.

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For precise measurement and display of the oil
level, the engine must be at operating tempera-
ture, i.e. following at least 6.2 miles/10 km of
uninterrupted driving. You can have the oil level
displayed while you are driving, or while the
vehicle is at a standstill on a level surface and
the engine is running.
Display in the instrument cluster
1.Push button1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
2.Press button2.
The oil level is checked and the reading dis-
played.

This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add engine oil as soon as possible, but no
more than 1 US quart/1 liter, refer also to
Adding engine oil on page205.
4Oil level is too high.
Too much oil will harm the engine.
Have the vehicle checked without
delay.<

tance remaining to the next oil service, refer
to page207. Have the system checked as
soon as possible.

Have the vehicle checked immedi-
ately; otherwise, the excess oil may
lead to engine damage.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page72. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil
until a corresponding message is shown
on the Control Display. Add oil within the next
125 miles/200 km; otherwise, the engine could
be damaged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil grades
Do not use any oil additives; otherwise,
you may cause engine damage.<
Approved engine oils
You BMW center will be happy to advise you
about the engine oils approved by the manufac-
turer of your vehicle.
The engine oil grade is a decisive factor for the
service life of the engine.
Approved engine oils can be found in the fol-
lowing specification:
Approved engine oils belong to the viscosity
classes SAE 0W-40, SAE 0W-30, SAE 5W-40,
and SAE 5W-30.
Alternative oil grades
If approved oils are not available, you can use
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page72:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page75; otherwise, the
effectiveness of Condition Based Service CBS
is not assured.<

Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, laboratory checked and
proven in the field, and offer optimal care and
protection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles.<
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page227.
>If necessary, fold in the outside rearview
mirrors, refer to page50.
>Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts.<
>In Convertibles, do not treat the convertible
top with wax. Ensure that a program is avail-
able that does not apply wax or is designed
specifically for convertibles.
Preparations before driving into an automatic
car wash:
>Unscrew the rod antenna
*.
>Deactivate the rain sensor
* to prevent unin-
tentional wiping.
>Remove additional attachments, e.g. spoil-
ers or telephone antennas, if there is a pos-
sibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Move the selector lever to position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
