For all season tires use the same inflation pressure as for summer tires.
For extra load tires 205/50 R 17 93 W use the same tire inflation pressure as for 
winter tires.
Tire inflation pressureObserve tire approval 
specificationsThe inflation pressures in the table 
apply to tires made by BMW-approved 
manufacturers. Your BMW center is 
familiar with these pressures. Higher 
pressures may be specified for tires 
made by other manufacturers. You will 
find a list of approved tires beginning 
on page 129.
Your vehicle is equipped with tires that 
meet US and European standards. We 
recommend the exclusive use of 
BMW-approved tires.

Tire Pressure Control (RDC)
*
The conceptThe RDC monitors the tire pressures at 
all four wheels, even when the vehicle 
is moving. The system provides an alert 
whenever the inflation pressure drops 
significantly below the specified pres-
sure in one or more tires. 
In order for the RDC system to "learn" 
the correct tire inflation pressure, first 
check the tire inflation pressure in all 
tires. Then compare these pressures 
with the tire inflation pressure chart 
(page 29) and adjust if necessary. Then 
activate the system. 
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not 
normal.
Activate the system Depending on the type of equipment, 
the switch either has the letters RDC on 
it or the RDC-symbol.
1 Turn the ignition key to position 2 
(do not start the engine).
2 Press the switch long enough for the 
indicator lamp in the instrument 
cluster to light up yellow for a few 
seconds.
3 After a few minutes driving time, the 
RDC sets the current inflation pres-
sure in the tires as the target values 
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire 
inflation pressure. Otherwise, the RDC 
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.460us297
Loss of tire pressureIf the inflation pressure has dropped 
significantly over a long period of time 
(which is normal for any tire), the indi-
cator lamp will come on with a yellow 
lamp.
This alerts you that you should have the 
tires inflated to the specified pressures 
as soon as possible.
If you are prompted to check the 
tire pressure shortly after a 
correction has been made, this indi-
cates that the corrected values were 
not accurate. Please check the inflation 
pressure again and make corrections 
according to the inflation pressure 
table. Then activate the system once 
again.<

Tire Pressure Control (RDC)

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with 
a red lamp. In addition, an acoustic 
signal goes off.
If this occurs, reduce vehicle speed 
immediately and stop the vehicle in a 
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the 
wheel and flat tire.
The space-saver spare tire is 
provided for temporary use only 
in the event of a tire failure. It does not 
have RDC electronics and is not moni-
tored. A full-size spare tire
 that has the 
same dimensions as the tires already 
mounted on the vehicle is equipped 
with the necessary RDC electronics, 
and will also be monitored once the 
tires have been mounted and the 
system activated.<
The RDC cannot alert you to 
severe and sudden tire damage 
caused by external factors.<
Have the tires changed by your 
BMW center.
Your BMW center has been trained to 
work with the RDC system and is 
equipped with the necessary special 
tools.<
System interferenceThe RDC may encounter interference 
from outside equipment or devices 
which use the same radio frequency.
The indicator lamp will come on with 
a yellow lamp during the malfunction. 
The indicator lamp also comes on
>in the event of a system fault 
>if a wheel is mounted without the 
RDC electronics 
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics 
are on board.
Please contact your BMW center for 
additional information.

Car care 

114n
To ensure maximum economy and a 
long service life, we request that you 
observe the following suggestions.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and road 
speeds, but do not exceed the following 
engine or road speeds during this time: 
4,500 rpm or 100 mph (160 km/h).
Obey your local and state maximum 
speed limits.
Refrain from using full throttle and avoid 
pressing the accelerator beyond the 
"kickdown" point.
After you have driven 1,200 miles 
(2,000 km), you can gradually increase 
the engine and road speeds.
You should also comply with these 
break-in procedures if the engine or 
differential is replaced at a later point.
TiresDue to technical factors associated 
with their manufacture, tires do not 
achieve their full traction potential until 
an initial break-in period has elapsed. 
Thus drive with extra care during the 
initial 200 miles (300 km).
Obey your local and state maximum 
speed limits.
When the vehicle is operated on 
wet or slushy roads, a wedge of 
water may form between the tire and 
the road surface. This phenomenon is 
referred to as aquaplaning, or hydropla-
ning, and can lead to partial or 
complete loss of traction, vehicle 
control and braking effectiveness. 
Reduce your speed on wet roads.<
Brake systemAfter approximately 300 miles (500 km), 
the brake pads and discs achieve the 
optimal pad surface and wear patterns 
required for trouble-free operation and 
long service life.
To break in the separate parking brake 
drums, apply the parking brake lightly 
when coasting to a standstill (at a traffic 
signal, for instance), provided that 
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on 
when the parking brake is applied.
Vacuum for the brake system servo unit 
on your BMW is available only when the 
engine is running. When you move the 
vehicle with the engine off Ð when 
towing, for example Ð substantially 
higher levels of pedal force will be 
required to brake the vehicle.
(500 km). Engage the gears carefully 
during the break-in period.
Break-in procedures 

115n
IndexDataTechnologyRepairsCar careControlsOverview
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 to 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. It is character-
ized by a partial or complete loss of 
contact between the tires and the road 
surface. The ultimate results are loss of 
steering and braking control.
Driving through water: 
When there is water on the roads, do 
not drive in it if it is deeper than 1 ft 
(30 cm), and then only at walking speed 
at the most, otherwise the vehicle can 
sustain damage to the engine, the elec-
trical systems and the transmission.
Roll-up cover:
Never use the rear window shelf to 
store heavy or bulky objects. If you do 
so, such objects could injure vehicle 
occupants during braking or evasive 
maneuvers or in a crash.
Clothes hooks:
When suspending clothing from the 
hooks, ensure that they will not obstruct 
the driver's vision. Do not hang heavy 
objects on the hooks. If you do, such 
objects could pose the risk of personal 
injury during braking or evasive maneu-
vers.
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 to 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 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 
disconnected.

Winter operationWinter is often accompanied by rapid 
changes in weather. Adaptions in 
driving style should be accompanied by 
preparations on the vehicle itself to 
ensure that your vehicle operates safely 
and trouble-free throughout the winter 
months.CoolantBe sure that the coolant mixture 
contains the year-round ratio of 50:50 
water and antifreeze/corrosion protec-
tion. This mixture will resist freezing to 
approx. Ð34 7 (Ð37 6). Replace the 
coolant every four years.LocksBMW door lock deicer can be used to 
free them if frozen. This deicer also 
contains lubricant.
After using the deicer, treatment with 
BMW lock cylinder grease is recom-
mended.
Rubber seals and components To prevent the weather stripping from 
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood 
and tailgate seals.
A full range of car care products is 
available from your BMW center.
BMW snow chains can be mounted on 
both summer and winter tires. Mount 
them in pairs on the rear wheels only 
and comply with the manufacturer's 
safety precautions. Do not exceed a 
maximum speed of 30 mph (50 km/h). 
In this type of exceptional situation 
where the snow chains are mounted, 
deactivate the ASC+T/DSC. Refer to 
page 79.
BMW 325xi: in a worst-case scenario, 
i.e. if your vehicle is stuck on one side 
or you cannot access one tire, then only 
one chain may be attached to a rear 
wheel for a short period of time.
Starting offWhen starting off from a full stop in 
deep snow or when "rocking" the 
vehicle to free it, it may be effective to 
deactivate the ASC+T/DSC system for 
a short period. Refer to page 79.Driving on low-traction road 
surfacesUse smooth, gentle pressure to control 
the accelerator pedal. Avoid excessive 
engine speeds and shift to the next 
higher gear at an early point. Downshift 
into the next lower gear on ascents or 
descents. Maintain an adequate 
distance between yourself and the 
vehicle ahead.
