Information on Hill St art Assist
Hill St art Assist holds th e ve hicle fo r a short
time when pulling aw ay on a hill under th e fo l‐
lowing conditions: R
The transmission is in position [ or ^ .R
The elect ri c pa rk ing brake is re leased.
This gives yo u enough time to mo ve yo ur fo ot
from th e brake pedal to th e accelera to r pedal
and depress it before th e ve hicle begins to ro ll.

WA RNING Risk of accident and inju ry
caused by th e ve hicle ro lling aw ay
Af te r a short time, Hill St art Assist no lon ge r
holds th e ve hicle and it can ro ll aw ay .

Ac tivating the HOLD function

The ë symbol appears in th e multifunction
displa y. The ar rows show on which side of th e
ro ad free parking spaces are located.
The parking space and, if necessar y, th e parking
direction can be selected as desired. Ac tive
Pa rk ing Assist calculates a suitable ve hicle path
and assists yo u in parking and ex iting th e park‐
ing space.
Ac tive Pa rk ing Assist ch anges ge ar, accelerates,
brakes and st eers th e ve hicle.
Ac tive Pa rk ing Assist is only an aid. It is not a
substitute fo r yo ur attention to th e sur ro undings.
The re sponsibility fo r safe maneu ve ri ng and
pa rk ing re mains with yo u. Make sure th at no
persons, animals or objects et c. are in th e
maneu ve ri ng ra nge.
Ac tive Pa rk ing Assist is canceled if, among ot her
th ings, one of th e fo llowing actions is car ri ed
out: R

Sy st em limitations
Objects located abo ve or below th e de te ction
ra nge of Ac tive Pa rk ing Assist are not de te cted
when th e parking space is being measured.
These are also no t ta ke n i nto account when th e
par king maneuver is calculated, e.g. ove rh anging
loads, ov erhangs or loading ra mp s of truc ks or
th e boundaries of parking spaces. In some cir‐
cums ta nces, Ac tive Pa rk ing Assist may th erefore
guide yo u into th e parking space prematurel y.

WA RNING Risk of accident due to
objects located abo ve or below th e
de te ction ra nge of Ac tive Pa rk ing Assist
If th ere are objects abo ve or below th e
de te ction ra nge, th e fo llowing situations may
arise: R
Ac tive Pa rk ing Assist may st eer to o early. R
Ve hicles with automatic transmis‐
sion: The ve hicle may not st op in front of
th ese objects.
This could cause a collision.

Sy st em limitations
The de te ction capability of Blind Spot Assi st can
be re st ri cted in th e fo llowing situations:R
There is dirt on th e sensors or th e sensors
are obscured. R
When th ere is poor visibility, e.g. due to fo g,
heavy ra in, snow or spr ay .R
If nar row ve hicles are within th e monitoring
ra nge, e.g. bicycles.
Wa rn ings may be issued in er ro r when driving
close to crash ba rr iers or similar solid lane bor‐
ders. Wa rn ings may be inter ru pte d when driving
alongside long ve hicles, fo r ex ample truc ks , fo r a
prolonged time.
Blind Spot Assist is not operational when re ve rs e
ge ar is engaged.
Fu nction of braking applications (Active
Blind Spot Assist)
If Ac tive Blind Spot Assi st de te cts a ri sk of a side
impact in th e monitoring ra nge, a cou rs e-cor‐
re cting brake application is car ri ed out. This is
designed to help yo u av oid a collision. The course-cor re cting brake application is av aila‐
ble in th e speed ra nge between appr ox imately
20 mp h (30 km/h) and 12 5 mp h (200 km/h).

Maximum permissible tire pressure: maxi‐
mum permissible tire pressure fo r one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated by dividing th e maxi‐
mum axle load of one axle by two.
PSI (pounds per square in ch ): st andard unit of
measurement fo r tire pressu re .
Aspect ra tio: ra tio between tire height and tire
width in pe rc ent.
Ti re pressure: pressure inside th e tire applying
an outward fo rc e to eve ry square inch of th e 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 re cted when
th e tires are cold.
Cold tire pressure: th e tires are cold when th e
ve hicle has been par ke d fo r at lea st 3 hou rs without direct sunlight on th e tires or th e ve hicle
has been driven fo r less th an 1 mile (1.6 km).
Ti re contact sur fa ce: th e part of th e tire th at
comes into con ta ct wi th th e ro ad.
Ti re bead: th e purpose of th e tire bead is to
ensure th at th e tire sits securely on th e wheel

th e manufacturing date.
Load-bearing index: th e load-bearing index is a
code th at con ta ins th e maximum load-bearing
capacity of a tire.
Tr action: traction is th e grip re sulting from fric‐
tion between th e tires and th e ro ad sur fa ce.
We ar indicator: nar row bars (tread we ar bars)
th at are distributed ove r th e tire con ta ct su rf ace.
