Fu
nctions of ASR (Acceleration Skid Control) ASR can neither
reduce therisk of an accident
nor override the la wsof ph ysics if the driver does
not pay attention when pulling away or accelerat‐
ing. ASR is only an aid. Alw ays adapt your driving
st yle to suit the pr evailing road and weather con‐
ditions.
If yo u activate or deactivate the all-wheel drive in
a ve hicle with this option, ASR will be deactivated
fo rth e duration of the activation/deactivation
process.
Ve hicles without steering wheel but tons: if
ASR is malfunctioning, the00E5 indicator lamp
lights up while the engine is running and the
engine output may be reduced (/ page 26).
ASR impr oves traction, i.e. the transfer of po wer
from the tires tothero ad sur face, for a sus tained
period and thereb y,also impr ovesth e driving sta‐
bility of theve hicle. If the drive wheels start to
spin, ASR brakes individual drive wheels and lim‐
its the engine torque. ASRthus significantly
assists you when pulling away and accelerating,
especially on wet or slippe ryroads.
If traction on thero ad sur face is not suf ficient,
eve n ASR will not allow youto pull away without
dif ficulty. The type of tires and totalwe ight of the
ve hicle as well as the gradient of thero ad also
play a crucial role.

Each tire, including the spare (if pr ovided),
should be checked monthly when cold and
inflated tothe inflation pressure recommen‐
ded bytheve hicle manufacturer on theve hi‐
cle placard or tire inflation pressure label. (If
yo ur vehicle has tires of a dif fere nt size than
th e size indicated on theve hicle placard or
tire inflation pressure label, you should de ter‐ mine
the proper tire inflation pressure for
th ose tires.)
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐
ing sy stem (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly unde r-inflated. Accord‐
ingly, when the low tire pressure telltale illu‐
minates, you should stop and check your tires
as soon as possible, and inflate them tothe
proper pressure. Driving on a significantly
under-inflated tire causes the tire toove rheat
and can lead totire failure. Under-inf lation
also reduces fuel ef ficiency and tire tread li fe,
and may af fect theve hicle's handling and
st opping ability. Please no tethat the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility tomaintain
cor rect tire pressure, even if under-inflation 314

Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate that

TPMS malfunction indicator is combined with
th e low tire pressure telltale. When the sys‐
te m de tects a malfunction, the indicator lamp
will flash for appro ximately one minute and
th en remain continuously illumina ted. This
sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illuminated,
th e sy stem may not be able todetect or sig‐
nal low tire pressure as intended. TPMS mal‐
functions may occur for a variet y of reasons,
including the ins tallation of replacement or
alternate tires or wheels on theve hicle that
pr ev ent the TPMS from functioning properly.
Alw aysch eck the TPMS malfunction telltale
af te rre placing one or more tires or wheels on

or alternate tires and wheels allow the TPMS
to continue tofunction properly. The sy
stem checks the tire pressure and thete m‐

means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in during thefirs t jour‐
