Tr a1c Sign Assist aids youby displaying de tected
speed limits and overtaking restrictions in the
inst rument cluster.
Since Tra1c Sign Assist also uses the data stored
in the navigation system, it can also update the
display without de tecting tra1c signs.
The camera also de tects tra1c signs with a restric-
tion indicated byan additional sign (e.g. when
we t).
% Tra1c signs are only displ ayed with there stric-
tion indicated byan additional sign in thefo l-
lowing cases:
R the tra1c signs must be obser ved with the
re striction
R the system is unable toclear lyde term ine
whe ther there striction applies
If th e system de tects that you are driving onto a
section of road in the wrong direction of tr avel, it
triggers a warning. This function is not available in
all countries.
Tr a1c Sign Assist is only an aid and is not alw ays
able tocor rectly display speed limits and overtak-
ing restrictions. The actual tra1c signs always
ha ve priority overth eTra1c Sign Assist displ ay.

R Ifth ere is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
R Ifth e tra1c signs are hard todetect, e.g. due
to dirt or sno w,or because they are co vered,

Blind Spot Assist cannot warndrivers in these
situations. #
Always pay careful attention tothe tra1c
situation and maintain a safe distance at

dangers (/ page 152).
If a vehicle is de tected abo vespeeds of appr ox-
imately 12 km/h and this vehicle subsequently
enters the monitoring range directly next toyour

lights up red.
If a vehicle is de tected close toyour vehicle in the
lateral monitoring range and you switch on the turn
signal indicator in the cor responding direction, a
wa rning tone sounds. The redwa rning lamp in the
outside mir ror 0ashes. If the turn signal indicator

WARNING
ARNING Risk of burns from hot compo-
nent parts in the engine compartment
Cer tain component parts in the engine com-
partment can be very hot, e.g. the engine, the
cooler and parts of theex haust system. #
Allow the engine tocool down and only
to uch component parts described in the
fo llowing. The engine oil becomes dirty during operation,
loses quality and also gradually loses volume.
Check the oil le velre gular lyand top up the oil or
ha ve itch anged if necessar y.
Re gular lych eck the 0uid le vel and the major
assemblies for leaks. If you de tect 0uid loss, for
ex ample, oil drops on theve hicle parking space,
consult a quali/ed specialist workshop as quickly
as possible. #
Only check the oil le vel when the engine is at
normal operating temp erature. 226

means of a tyre pressure sensor.
Ne w tyre pressure sensors, e.g. in winter tyres, are

Fu rthermore, the use of cer tain tyre types in

tyres) and make.
R Only /t wheels of the same size and tread

sions and that the cor rect tyre type is
obser ved. R
When using a spare wheel (di.erent from the
wheel tobe replaced), you must not exceed a
to p speed of 80 km/h.
R The tyre pressure of the spare wheel must be
ch ecked before starting a journey and, if nec-
essar y,adjusted (/ page 254).
R Have the spare wheel replaced bya quali/ed
specialist workshop. The
following should be checkedre gular ly, particu-
