R A front wheel drives overth is lane marking.
Yo u will also be guided back into your lane by
means of a course-cor recting brake application

Ac tive Lane Keeping Assist can neither reduce
th erisk of an accident if youfa ilto adapt your driving
style nor override the la wsof ph ysics. It
cannot take into account road, weather or traf fic
conditions. Active Lane Keeping Assist is only an
aid. You are responsible for maintaining a safe
dis tance totheve hicle in front, forve hicle
speed, for braking in good time and forst ay ing
in lane.
Ac tive Lane Keeping Assist can bring theve hicle
back into the lane with a lane-cor recting brake
application. In the case of a broken lane marking
being de tected, a brake application will only be
made if a vehicle has been de tected in the adja‐
cent lane. Oncoming tra ffic can be de tected.
Ve hicles with Driving Assistance pac kage or
Driving Assistance Plus pa ckage: overtaking
ve hicles and vehicles in adjacent lanes can also
be de tected.

WARNING Risk of an accident when
using the bicycle rack incor rectly
The bicycle rack may become de tach ed from
th eve hicle in thefo llowing cases:
R the permissible load capacity of the
trailer hitch is exceeded.
R the bicycle rack is used incor rectl y.
R the bicycle rack is secured tothe ball
neck beneath the ball head.
Obser vethefo llowing foryo ur ow n sa fety
and that of other road users:
R always adhere tothe permissible load
capacity of the trailer hitch.
R only use the bicycle rack totranspo rt
bicycles.
R always mount the bicycle rack properly by
attaching tothe ball head and the ball
neck guide pin, if possible. R
when transporting four bic ycles, alw ays
use bic ycle rack s which ha veadditional
suppo rton the ball neck guide pin.

Depending on the bicycle rack 's design, dif fere nt
numbe rsof bicycles can be transpor ted.
The following bicycle rack designs are possible:
R When mounted byattaching toball head 1,
th e maximum load capacity is 75kg.Up to
th re e bicycles can be transpor ted. 316
Driving and pa rking

R
When mounted on ball head 1and guide
pin 2, the maximum load capacity is
10 0kg .Up tofour bic ycles can be transpor‐
te d.
The load capacity is calculated from thewe ight
of the bicycle rack and the bicycle rack load.
The vehicle's driving characteristics change
when a bicycle rack isfitted. Adapt your driving
st yle accordingly. Drive carefully and maintain a
safe dis tance.
When using a bicycle rack , set the tyre pressure
fo r increased load on there ar axle of theve hicle.
Fu rther information on the tyre pressure can be
fo und in the tyre pressure table (/ page572).
Note s on loading
The larger the dis tance between the load's
cent reof gr avity and the ball head, the greater
th e load on the trailer hitch.
Obser vethefo llowing no tes:
R Mount heavy bicycles as close totheve hicle
as possible. R
Alw ays distribute the load on the bicycle rack
as eve nly as possible across theve hicle's
longitudinal axis.
Mercedes-Benz recommends removing all
de tach able parts from bicycles (e.g. bask ets,
ch ild seats, rech arge able bat teries) before load‐
ing them onto the bicycle rack . This will impr ove
th e aerodynamic resis tance and centre of gr avity
of the bicycle rack.
Alw ays secure the bicycles toprev ent them from
moving around and check that they are secure at
re gular inter vals.
Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
impaired. In addition, the aerodynamic resist‐
ance and the load on the trailer hitch will
increase. Distribution of
the load on the bicycle rack
