Yo u can help toprotect the environment by
operating your vehicle in an environmentally
re sponsible manner. Please obser vethefo l‐
lowing recommendations on ope rating condi‐
tions and pe rsonal driving style.
Operating conditions:
00BBMake sure that the tire pressure is cor‐
re ct.
00BBDo not car ryany unnecessary weight
(e.g. roof luggage rack s once you no
longe r need them).
00BBAd here tothe service inter vals.
A regularly serviced vehicle will contri b‐

Pe rsonal driving style:
00BBDo not depress the accelera tor pedal
when starting the engine.
00BBDo not warm upthe engine while the
ve hicle is stationar y.
00BBDrive carefully and maintain a suitable
dist ance from theve hicle in front.

and braking.
00BBChange gear in good time and use each

Environmental issues and recommendations:
It is recommended that youre -use or recycle
materials ins tead of just disposing of them. The

Damage totheve hicle can arise from viola‐
tion of these operating instructions.
This damage is not co vered either bythe
Mercedes-Benz implied warranty or bythe
New‑ or Used- Vehicle Warrant y.
00BBFollow the instructions in these operat‐
ing instructions on proper operation of
yo ur vehicle as well as on possible vehi‐
cle damage.
QR codes for the rescue card
The QR code is secured in the fuel filler flap and
on the opposite side on the B-pillar. In theeve nt
of an accident, rescue services can use the QR
code toquickly find the appropriate rescue card
fo ryo ur vehicle. The cur rent rescue card con‐
ta ins the most impor tant information about your
ve hicle in a compact form , e.g. thero uting of the
electric lines.
Fu rther information can be obtained at http://

Ve hicle data storage
Information from electronic control units
Yo ur vehicle is equipped with electronic contro l
units. Some of these are necessary forth e safe
operation of your vehicle, while some assist you
when driving (driver assis tance sy stems). In
addition, your vehicle pr ovides con venience and
enter tainment functions, which are also made
possible byelectronic control units.
Elect ronic control units contain da tamemories
which cantemp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing status, component loads, mainte nance
re qu irements and tech nical events or malfunc‐
tions.
In general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings, forex ample:

During kickdown, you cannot shift gears using
th esteering wheel gearshift paddles. The auto‐

when the maximum engine speed is reached to
pr otect the engine from overrev ving.
00BBEase off the accelera tor pedal once the
desired speed is reached.
Glide mode function
Wi th an anticipatory driving style, glide mode
helps youto reduce fuel consum ption.
Glide mode is characterized bythefo llowing:
RThe combustion engine is disconnected from
th e driv etra in and theve hicle continues to

RThe transmission position 005Bis displa yed in
green in the multifunction displa y.
Glide mode is activated if thefo llowing condi‐

RDrive program Eis selected.
RThe speed is wi thin a suitable range
RThe cours e ofthero ad is suitable, e.g. no
st eep uphill or downhill gradients or tight
bends.
RYo u are no longe r depressingthe accelera tor

Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive
(engine management) when in drive program

Glide mode is deactivated again if one of the
conditions is no longer met.
Ve hicles with Driving Assistance Package,
Ac tive Di stance Assist DI STRONIC or Active

WARNING Risk of accident due toinsuf‐
fi cient or excessive tire pressure
Underinfla ted or overinfla ted tires pose the
fo llowing risks:
RThe tires may bur st, especially as the
load and vehicle speed increase.
RThe tires may wearexc essively and/or
une venly, which may greatlyimpair tire
traction.
RThe driving characteristics, as well as
st eering and braking, may be greatly
impaired.
00BBComply with there commended tire
pressure and check the tire pressure of
all tires including the spare wheel regu‐
larly:
Rat least once a month
Rwhen the load changes
Rbefore embarking on a longe r journey

WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics.

all the tires, including the spare wheel.
Tire pressure which is too low can cause:
RTire defects as a result of overheating
RImpaired handling characteristics
RIrre gular wear
RIncreased fuel consum ption

WARNING Risk of accident from exces‐
sive tire pressure
Ti re s with excessively high pressure can
bur stbecause they are damaged more easily
by highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular
