Automatic Stability Control plus
Traction (ASC+T)This system is designed to enhance
operating stability, especially while
accelerating and during cornering.
ASC+T automatically assumes opera-
tion each time you start the engine.
The indicator lamp in the instrument
cluster goes out shortly after you switch
on the ignition.
To deactivate the systemPress the button; the indicator lamp
comes on.To reactivate the systemPress the button again; the indicator
lamp goes out.Indicator lamp flashesThe system is actively regulating drive
torque in response to monitored vehicle
operating conditions.Indicator lamp fails to go out after
the engine is started, or comes on
in the course of normal vehicle
operationThe system has a defect. The vehicle
normally remains operational even with-
out ASC+T. Consult your authorized
BMW Retailer for repair.When ASC+T is switched off, you drive
with a conventional drive system. We
recommend that you deactivate the
system for increased traction
dwhen rocking the vehicle or starting
off in deep snow or on loose surfaces
(refer to "Starting off", page 10 5)
dor when driving with snow chains.
b
But even with ASC+T the laws of
physics can not be suspended. Any
consequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. We
therefore urge you to avoid using the
additional safety margin of the system
as an excuse for taking risks.c
For more details, please refer to section
"Advanced Technology" on page 156.

Failure of one brake circuitPedal travel increases, more pressure is
required at the pedal.
The remaining circuit continues to pro-
vide good braking response.a
In the event of any malfunction in
the brake system, consult the nearest
BMW Retailer as soon as possible.cThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your
progress through the winter remains
safe and trouble-free.
CoolantEnsure that the coolant contains the
year-round 50:50 ratio of water and
antifreeze with corrosion inhibitor. This
mixture provides protection against
freezing down to approximately -345F
(-376). Replace the coolant every
three years.Lockscan be made operative again using
BMW lock de-icer. This de-icer also
contains lubricants.
In addition, a treatment with BMW lock
cylinder grease is recommended.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 luggage compartment lid seals.b
A complete range of car-care
products is available from any autho-
rized BMW Retailer.c
Snow chainsBMW snow chains
* can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and observe the manufacturer's safety
precautions. Do not exceed a maximum
speed of 30 mph (50 km/h). For maxi-
mum traction, deactivate ASC+T when
driving with snow chains mounted, refer
to page 84.
Starting offWhen driving off in deep snow or "rock-
ing" the vehicle to free it, you should
switch off ASC+T, refer to page 84. Driving on low-traction road
surfacesOperate the accelerator pedal sensi-
tively, avoid high engine speeds and
shift up to the next-higher gear early.
Shift down into the next lowest gear
when approaching uphill or downhill
grades. Maintain an adequate distance
between yourself and the car ahead.
