You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes-
Benz. This could lead to malfunctions in
safety-relevant systems, e.g. the brake sys-
tem. Use only genuine Mercedes-Benz parts
or parts of equal quality. Only use tires,
wheels and accessories that have been spe-
cifically approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been spe-
cifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Only genuine Mercedes-Benz parts should
therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.

tain a supply of genuine Mercedes-Benz parts
for necessary service and repair work. In addi-
tion, strategically located parts delivery cen-
ters provide quick and reliable parts service.
Always specify the vehicle identification num-
ber (VIN) when ordering genuine Mercedes-
Benz parts (
Ypage 376).
Operator's Manual

applies to safety-relevant systems and func-
tions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations.
The original purchase agreement lists all sys-
tems installed in your vehicle.
Should you have any questions concerning
equipment and operation, please consult an
authorized Mercedes-Benz Center.The Operator's Manual and Maintenance
Booklet are important documents and should

let with you when you bring the vehicle to an
authorized Mercedes-Benz Center. The ser-
vice advisor will record every service for you
in the Service and Warranty Booklet.

tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seatbelt.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
Persons under 5 ft (1.50 m) in heightcannot
fasten the seat belt correctly without an addi- tional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fas-
tened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restrain t
systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height istraveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be
appropriate to the age, weight and size of
the child
Ralways observe the instructions and safety
notes in the "Children in the vehicle" sec-
tion of this Operator's Manual (
Ypage 58) in addition to the child
restraint system manufacturer's installa-
tion instructions
Rbe sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (
Ypage 51)
GWARNING
The seat belts may not perform their intended protective function if:
Rthey are damaged, modified, extremely
dirty, bleach or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Ten-
sioning Devices could accidentally trigger or
fail to deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-
shop.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
Sports seat or AMG Performance seat: this
seat is designed for the standard three-point
seat belt. If you install anothe r mu
lti-point
seat belt, e.g. sport or racing seat belts, the
restraint system cannot provide the best level
of protection.
GWARNING
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of an accident. This poses an increased risk of
injury or even fatal injury.

Safety
Z

The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving.
Off-road ABS
An ABS system specifically suited to off-roadterrain is activated automatically once the off-
road program is activated (
Ypage 199).
At speeds below 20 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces the stopping distance on off-road terrain. This
limits steering capability.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 65).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
COLLISION PREVENTION ASSIST
PLUS
General information
iObserve the "Important safety notes" sec-
tion (
Ypage 65).
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous braking function and adaptive
Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end
collision with a vehicle ahead or reduce the
effects of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision
warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION
PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Important safety notes
Detection of hazardous situations can be par-
ticularly impaired by:
Rthere is dirt on the sensors or anything else covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rnew vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Observe the important safety notes in the
"Breaking-in notes" section (
Ypage 148).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-

Both exterior mirrors fold in or out.
iMake sure that the exterior mirrors are
always folded out fully while driving. They
could otherwise vibrate.
iIf you are driving faster than 30 mph
(47 km/h) , you can no longer fold in the
exterior mirrors.
Folding the exterior mirrors in or out
automatically
This function is only available in Canada.
If the "Fold in mirrors when locking" function
is activated in the on-board computer
(
Ypage 231):
Rthe exterior mirrors fold in automatically as
soon as you lock the vehicle from the out-
side.
Rthe exterior mirrors fold out again automat-
ically as soon as you unlock the vehicle and
then open the driver's or front-passenger
door.
iIf the exterior mirrors have been folded in
manually, they do not fold out.
Exterior mirror pushed out of position
If an exterior mirror has been pushed out of
position, proceed as follows:
XVehicles without electrically folding
exterior mirrors: move the exterior mirror
into the correct position manually.
XVehicles with electrically folding exte-
rior mirrors: press and hold mirror-folding
button (
Ypage 109) until you hear a click
and then the mirrors engage in position.
The mirror housing is engaged again and
you can adjust the exterior mirrors as usual
(
Ypage 109).
Automatic anti-glare mirrors
GWARNING
Electrolyte may escape if the glass in an auto-
matic anti-glare mirror breaks. The electrolyte
is harmful and causes irritation. It must not
come into contact with your skin, eyes, res-
piratory organs or clothing or be swallowed.
There is a risk of injury.
If you come into contact with the electrolyte,
observe the following:
RRinse off the electrolyte from your skin
immediately with water.
RImmediately rinse the electrolyte out of
your eyes thoroughly with clean water.
RIf the electrolyte is swallowed, immediately
rinse your mouth out thoroughly. Do not
induce vomiting.
RIf electrolyte comes into contact with your
skin or hair or is swallowed, seek medical
attention immediately.
RImmediately change out of clothing which
has come into contact with electrolyte.
RIf an allergic reaction occurs, seek medical
attention immediately.
The "Automatic anti-glare mirrors" function is
only available if the vehicle is equipped with
the "Mirrors package".
