Childrestra int sy stems on the front
passenger seat
Note s onchild restra int sy stems on the front
passenger seat
Ac cident statistics show that children secured in
th ere ar seats are safer than children secured in
th e front seats. Forth is reason, Mercedes-Benz
stro ngly advises that you ins tall a child restra int
sy stem on a rear seat.
If it is absolutely necessary toins tall a child
re stra int sy stem on the front passenger seat,
alw ays obser vethe information on the automatic
front passenger front airbag shutoff
(
→page 43).
By doing this, you can avoidrisks caused by:
RAch ild restra int sy stem that is not de tected
by the automatic front passenger front airbag
shutoff.
RThe unintentionally deactivated front
passenger airbag.
RIncor rect positioning of thech ild restra int
sy stem.

th e sensors in the front and rear bumper must
de tect the object while you are driving past it. During
the parking procedure or maneuvering,
objects are de tected as theve hicle drives past.
If yo usteer in the direction of a de tected obs ta‐

th e maximum permissible weight in kilog rams or
lbs for which a tire is appr oved.
Maximum permissible tire pressure: maxi‐
mum permissible tire pressure for one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated bydividing the maxi‐
mum axle load of one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressure .
Aspect ratio: ratio between tire height and tire
width in pe rcent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the tire.
The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be cor rected when
th e tires are cold.
Cold tire pressure: the tires are cold when the

the tires or theve hicle
has been driven for less than 1 mile (1.6 km).
Ti re contact sur face: the part of the tire that

code that con tains the maximum load-bearing
capacity of a tire.
Tr action: traction is the grip resulting from fric‐
