guide you into the parking space prematurely. &
WARNING Risk of accident due to
objects located abo veor below the
de tection range of Active Parking Assist
If th ere are objects abo veor below the de tec‐
tion range, thefo llowing situations may arise:
R Active Parking Assist may steer too early.
R The vehicle may not stop in front of these
objects.
This could cause a collision. #
Inthese situations, do not use Active
Pa rking Assist. Sn
owfa ll or heavy rain may lead toa parking
space being measured inaccuratel y.Pa rking
spaces that are partially occupied bytrailer dr aw‐
bars might not be identified as such or be meas‐
ured incor rectly. Only use Active Parking Assist
on le vel, high-grip ground.
Do not use Active Parking Assist in thefo llowing
situations, among others:
R inextreme weather conditions such as ice,
pac ked snow or in heavy rain
R when cornering
R for parking spaces which are not on the same
le ve l as thero ad, e.g. not on the pa vement
R when transporting a load that pr otru des
be yond theve hicle
R when snow chains are fitted
Ac tive Parking Assist may also display parking
spaces that are not suitable for parking, for
ex ample:
R parking spaces where parking is prohibited
R parking spaces on unsuitable sur faces
Ac tive Parking Assist will not assist you with
parking spaces perpendicular tothe direction of
tra vel in thefo llowing situations:
R if two parking spaces are located immediately
next toeach other
R ifth e parking space is immediately next to a
low obs tacle such as a kerb
R ifyo u are parking forw ards Ac
tive Parking Assist will not assist you with
parking spaces parallel or perpendicular tothe
direction of tra vel in thefo llowing situations:
R ifth e parking space is on a kerb
R ifth e sy stem deems the parking space tobe
bloc ked, such as byfoliage or grass paving
bloc ks
R ifth e area is too small forth eve hicle to
manoeuvre into
R ifth e parking space is bordered byan obs ta‐
cle, e.g. a tree, a post or a trailer

WARNING Risk of accident due toinsuf‐
fi ciently secu ring theve hicle against roll‐
ing away when exiting theve hicle
If yo u lea vethe driver's seat when theve hicle
is being braked byActive Parking Assist onl y,
it could rollaw ay inthefo llowing situations:
R ifth ere is a malfunction in the sy stem or
in the po wer supp ly.
R ifth e electrical sy stem in the engine com‐
partment, the battery or the fuses are
ta mp ered with.
R ifth e battery is disconnected.
R ifth eve hicle is accelerated, e.g. byave hi‐
cle occupant. #
Before leaving the driver's seat, alw ays
secure theve hicle against rolling away. #
Bring theve hicle safely toast op when the
parking symbol with an ar rowshows the
desired parking space. &
WARNING Risk of accident due tovehi‐
cle swinging out while parking or pulling
out of a parking space
While parking or pulling out of a parking
space, theve hicle swings out and can drive
onto areas of the oncoming lane.
This could cause youto collide wi thobjects
or other road users. #
Pay attention toobjects and other road
users. #
Where necessar y,stop theve hicle or
cancel the parking procedure with Park‐
ing Pilot. 17 0

TENTION ASSI ST Fu
nction of ATTENTION ASSI ST
AT TENTION ASSIST can assist you on long,
mon otonous jou rney s, e.g. on mo torw ays and
trunk roads. If ATTENTION ASSIST de tects indica‐
to rs of fatigue or increased lapses in concentra‐
tion on the part of the driver, it suggests taking a
brea k.
AT TENTION ASSIST is only an aid. It cannot
alw ays de tect dr owsiness or increased lapses in
concentration in good time. The sy stem is not a
substitute for a well-res ted and attentive driver.
On long journe ys,ta ke regular and timely breaks
th at allow youto rest properly.
If fatigue or increased lapses in concentration are
de tected, theATTENTION ASSIST: Take a break!
wa rning appears in the instrument clus ter.
Yo u can ackn owledge the message and take a
break if necessar y.Ifyo u do not take a break and
AT TENTION ASSIST continues todetect increased
lapses in concentration, you will be warned again
af te r a minimum of 15minutes.
If a warning is displa yed in the instrument clus ter,
th e multimedia sy stem of fers to sear chfor a rest
area. You can select a rest area and start naviga‐
tion tothis rest area. This function can be activa‐
te d and deactivated in the multimedia sy stem. Yo

The bar display is then dimmed. This is the case,
fo rex ample, if you are predominantly driving at a
speed below 60 km/h or abo ve200 km/h.

Have theve hicle checked immediately
at a qualified specialist workshop. If
yo u are uncer tain rega rding the operational

soon as possible. Inform a qualified specialist
wo rkshop.
The on-board computer will show only messages

If yo uch ange your vehicle's wheel size, check its
assignment tothe wheel size group
(/ page 258). If the assignment changes with‐

DANG ER Risk of exhaust gas poisoning
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Exhaust
ga ses can enter theve hicle interior if theta il‐
gate is open when the engine is running,
especially if theve hicle is in motion. #
Always switch off the engine before
opening theta ilgate. #
Never drive with theta ilgate open. &
WARNING Risk of injury from unsecured
objects in theve hicle
When objects are unsecured or inadequately
secured, they can slip, tip over or be thro wn
about, striking vehicle occupants.
This also applies to:
R luggage or loads
R seats which ha vebeen remo ved and are
being transpor ted in theve hicle in an
exc eptional case
There is a risk of injur y,particularly in the
ev ent of braking manoeuvres or abrupt
ch anges in direction. #
Alwaysstow objects in such a wayth at
th ey cannot be tossed about. #
Before tr avelling, secure objects, lug‐
ga ge or load topreve ntthem slipping or
tipping over. #
When a seat is remo ved, keep it prefera‐
bly outside theve hicle. &
WARNING Risk of accident due toincor‐
re ctly positioned load
The centre of gr avity of the load can be too
high and/or toofa rto wa rdsth ere ar.
This can significantly impair handling as well
as steering and braking characteristics. #
Always make sure that the cent reof
gr av ity of the load is between the axles
and as low as possible near there ar
axle. &
WARNING Risk of accident due to
exc eeding the permissible wheel/axle
loads or the gross vehicle weight
The driving characteristics, as well as steering
and braking, may be greatly impaired. Over‐
loaded tyres may overheat and bur stas a
consequence. #
When transpo rting a load, alw ays
obser vethe permissible wheel loads,
axle loads and the maximum permissi‐
ble gross mass forth eve hicle (including
occupants). &
WARNING Risk of injury if unsuitable
climbing aids are used
In theev ent that you use openings in the
bodywork or attachments as steps, you
could:
R Slip and/or fall.
R Damage theve hicle and thus slip and fall. #
Always use non-slip, stable climbing
aids, e.g. a suitable ladder. *
NO
TEDama gecaused bythe use of
openings in the bodywork or de tach able

Do not use the guide of the sliding door
(car riage) as a step. If
yo u are using a roof luggage rack , please no te
th e maximum roof load and the maximum load
capacity of thero of luggage rack ( /page 278).
The handling characteristics of your vehicle are
dependent on the load distribution.
Therefore, please obser vethefo llowing no tes
when loading:
R the load must not pr otru de abo vethe upper
