>reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel specifications
Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
>328i/xDrive: 87
>335i/xDrive: 89.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
driveability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter driveability problems
which you suspect could be related to the fuel
y o u a r e u s i n g , w e r e c o m m e n d t h a t y o u r e s p o n d
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Wheels and tires
Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
Run-Flat Tires. A flat tire will seriously impair
your vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure,
reinitialize the Tire Pressure Monitor,
refer to page87, or the Flat Tire Monitor, refer
to page85.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's-side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed, otherwise
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise tire
damage and accidents could occur.<
Observe all national and local maximum speed
limits, otherwise violations of the laws could
occur.

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 page73:
>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 page76; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<

Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Socket for On-Board
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.
Exhaust emission values
The warning lamp lights up:
The exhaust emission values have
worsened. Have the car checked as
soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under certain conditions. This
indicates excessive misfiring in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas cap is then tightened, the
warning lamp should go out within a few days.
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a service contract for BMW Assist, cer-tain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.

Replacing components
222 4.Apply gentle pressure to the bulb while
turning it to the left for removal and replace-
ment.
5.Attach the bulb holder.
6.Reattach the trim of the luggage compart-
ment lid and the holder for the warning tri-
angle.
License plate lamp, center brake lamp,
parking/tail lamp
These lamps use LED technology for operation.
In the event of a malfunction, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
Changing wheels
Your BMW is equipped with Run-Flat Tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page86.
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall, refer to
Run-Flat Tires, page204.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page204.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page225.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page75.
