To preser vethe engine during thefirs t1, 500 km:
R drive at varying road speeds and engine
speeds.
R drive theve hicle in drive program A
or ;.
R change gear before there v counter needle is
00C3 ofthewa yto there d area of there v coun‐
te r.
R do not shift down a gear manually in order to
brake.
R avoidoverstra ining theve hicle, e.g. driving at
full thro ttle.
R vehicles with automatic transmission: do
not depress the accelera tor pedal be yond the
pressure point (kickdown). R
only increase the engine speed gradually and
accelera tetheve hicle tofull speed af ter
1, 500 km.
This also applies when the engine or parts of the
driv etra in ha vebeen replaced.
Please also obser vethefo llowing running-in

WARNING Risk of accident due to
objects in the driver's foot we ll
Objects in the driver's foot we ll may impede
pedal tr avel or block a depressed pedal.
This jeopardises the operating and road
saf ety of theve hicle. 0007
Stow all objects in theve hicle securely
so that they cannot getinto the driver's
fo ot we ll. 0007
Alw aysfit th efloor mats securely and

WARNING Risk of accident due to
unsuitable foot we ar
Operating the pedals may be impaired by
we aring unsuitable foot we ar, e.g.:
R plat form shoes
R high-heeled shoes
R slippers 0007
Alw ayswe ar suitable foot we ar when
driving so that you can operate the ped‐
als safel y. 000A
WARNING Risk of accident when switch‐
ing off the ignition when driving
If yo u swit choff the ignition while driving,
saf ety functions are restricted or no longer
av ailable. This may af fect the po werst eering
sy stem and the brake forc e boosting, for
ex ample.
Yo u will then need touse considerably more
fo rc eto steer and brake. 0007
Do not switch off the ignition while driv‐
ing. 000A
DANG ER Risk of fata l injuries due to
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and can lead topoisoning. 0007
Never lea vethe engine running in an
enclosed space wi thout suf ficient venti‐
lation. 000A
WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. 0007
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. 000A
DANG ER Risk of fata l injuries due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case, forex ample, if theve hi‐
cle is stuck in sn ow. 0007
When the engine or thest ationary
heater are running, keep theta ilpipe
and the area around theve hicle clear of
sno w. 0007
Open a window on the side of theve hi‐
cle facing the wind toensure an ade‐
qu ate supply of fresh air. 000A
WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il. 17 2

Have the cause rectified immediately at
a qu alified specialist workshop. Limited braking ef
fect on salt-trea tedro ads:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe

To preve nt salt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions R
carefully depress the brake pedal at the end
of the journey and when starting the next

adjust the driving style fo rth ero ute ahead, sa ve
fuel and recuperate. If the sy stem de tects an
eve nt ahead, e.g. a speed limit or a roundabout,
it will appear on the multifunction displa y.The
fo llowing symbols can be displa yed: Not all
events can be displa yed, depending on the
engine type. 1

2 Distance totheeve nt ahead
3 "Foot off the accelerator" prom pt
A di fferent number of segments 2will light up
around the symbol depending on the dis tance to
th eeve nt ahead:
R Few segments: theev ent ahead is near.
R Many segments: theev ent ahead is fur ther

The "Foot off the accelerator" symbol 3will
appear on the multifunction display as well as
th e "Event ahead" symbol 1. In drive pro‐
gram ;, the "Foot off the accelera tor" sym‐ 176
Driving and pa rking

bol
3will also appear on the head-up display
beside the transmission displa y.
When theve hicle nears an event, ECO Assist will
calculate the optimal speed for maximum fuel
economy and recuperati veenergy based on the
dis tance, speed and downhill gradient. The "Foot
off the accelera tor" 3 symbol will appear on
th e multifunction displa y.
If th e driver lifts off the accelera tor pedal in
good time, there maining segments on the dis‐
play will turn green until theev ent shown is
re ached. The driv etra in will be set for maximum
fuel econom y.The vehicle will coast, with the
combustion engine switched off if necessar y,
and recuperate on its own using the electric
mo tor.Re cuperation will charge the batter y.
If th ere is no response tothe "Foot off the accel‐
erator" 3prom pt,th e segments will remain
white.
The event will be shown for a short time af ter it
has been passed.
If th eeve nt in volves a vehicle ahead and when
th e coast-down recommendation is given, all
segments will immediately turn green once there is a
response tothe "Foot off the accelerator"
3 prom pt.
If th e sy stem does not inter vene du ring the
eve nt ahead, no thing will be displa yed. The sys‐
te m is passive.
ECO Assist is active only in drive program ;
(maximum recuperation) and A(reduced
re cuperation).
Ve hicles with a 48 V on-board electrical sys‐
te m (EQ Boo sttech nology): in drive program
A, only theeve nt "Vehicle ahead" is dis‐

Sy stem limitations
ECO Assist can function more precisely if the
ro ute is main tained when route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve hicle
in front, forve hicle speed and for braking in
good time. The driver must be ready tobrake at all times ir
respective of whe ther the sy stem
inter venes.
The sy stem may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, high lyvariable
shade conditions, rain, sno w,fog or heavy
spr ay.
R Ifth ere is glare, e.g. from oncoming traf fic,
di re ct sunlight or reflections.
R Ifth ere is dirt on the windscreen in the vicin‐
ity of the multifunction camera or the camera
is mis ted up, damaged or obscured.
R Ifth e traf fic signs are ha rdtodetect, e.g. due
to dirt or snow or insuf ficient lighting, or
because they are obscured.
R Ifth e information on the navigation sy stem's
