engine MERCEDES-BENZ V-CLASS MPV 2021 Owner's Guide

#
Avoid high engine speeds and driving at
full thro ttle until the engine has reached
its operating temp erature. Note
s on short-distance trips
If th eve hicle is predominantly used in short-dis‐
ta nce driving, a fault in the automatic cleaning
function of the diesel particulate filter can occur.
Due tothis, fuel may also accumulate in the
engine oil and cause engine failure.
During automatic cleaning, extreme lyhot exhaust
ga ses escape from theex haust pipe. Maintain a
dis tance of at least 1 m to other objects, e.g.
par kedve hicles, in order toavoid material dam‐
age.
If yo u main lydrive short dis tances, you should
drive on a mo torw ay or go for a country drive for
20 minutes every500 km. This facilitates the
re ge neration of the diesel particulate filter.
Information about driving abroad
Service
An extensive Mercedes-Benz service is also avail‐
able abroad. Ne vertheless, please remember that
services or spare parts may not be available
immediatel y.The releva nt wo rkshop directories
are available from a Mercedes-Benz Service
Cent re.
Fu el
In some countries, only fuels with an inc reased
sulphur con tent are available.
Uns uitable fuel can cause engine damage. Yo u
can find fur ther information under "Fuel"
(/ page 270).
Ad Blue ®
Ad Blue ®
is not available in suf ficient quality in all
countries. Therefore, check theAd Blue ®
leve l,
particular lybefore driving outside Europe
(/ page 148). Consul t aqualified specialist
wo rkshop for advice.
Yo u can find information about AdBlue ®
in "Oper‐
ating fluids and capacities" (/ page271).
Low beam
In countries in whi chtraf fic drives on the oppo‐
site side of thero ad from the count ryin which
th eve hicle is regis tere d, you will ha vetoswitch
th e headlamps tosymmetrical dipped beam. This
will pr event oncoming traf fic from being dazzled.
Symm etrical dipped beam will no longer illumi‐
nate the edge of the car riag ewa y as far or as
high. Ve
hicles with halogen headlamps:
It is not necessa ryto change the headlamps over
to symmetrical dipped beam. The statutory
requ irements of the count ries in which tra ffic
drives on the opposite side of thero ad from the
country in whi ch theve hicle is regis tere d are also
met without changing over.
Ve hicles with LED headlamps:
Yo u can set the low beam for driving on theright
or left via the on-board computer (/ page189).
Information about transport byrail
Tr ansporting your vehicle byrail may be subject
to cer tain restrictions or requ ire special meas‐
ures tobe take n in some countries due tovarying
tunnel heights and loading standards.
Yo u can obtain information about this from a
Mercedes-Benz Service Cent re.
Information on brakes &
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 overheat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. *

Do not permanently depress the brake

Touse braking ef fect of the engine, shift
to a lo werge ar in good time. Downhill
gradients
On long and steep downhill gradients you should
obse rveth efo llowing instructions:
R invehicles with an automatic transmission,
shift down toshift ranges 2or 1in good time
so that the engine is running at a medium to
high engine speed (/ page143).
R invehicles with a manual transmission, shift
down toa lo werge ar in good time, so that the
engine is running at a medium tohigh engine

Obser vethe driving tips (/ page137).
Yo uth ereby make use of the braking ef fect of the
engine and do not ha vetobrake as of tento main‐
tai nth e speed. This relie vesth e load on the
service brake and pr events the brakes from over‐
heating and wearing tooqu ickl y.
Heavy and light loads
If th e brakes ha vebeen subjected toa heavy
load, do not stop theve hicle immediatel y.Drive
on for a short while. The brakes cool down more
qu ickly in the air flow.
If th e brakes ha vebeen used only moderately,
yo u should occasionally test their ef fectiveness.
To do this, brake more firm ly from a higher speed
while pa ying attention tothe traf fic conditions.
The brakes will grip better as a result.
We tro ad sur faces
If yo u ha vebeen driving for a long time in heavy
ra in without braking, there may be a dela yed
re sponse when youfirs t apply the brakes. This
may also occur af ter driving thro ugh a car wash
or deep water.Yo u must depress the brake pedal
more firm ly. Maintain a grea ter dis tance tothe
ve hicle in front.
While paying attention tothe traf fic conditions,
yo u should brake theve hicle firm lyafte r driving
on a wetro ad sur face or thro ugh a car wash. This
heats the brake disks so that they dry more
qu ickl y,which pr otects them against cor rosion.
Limited braking ef fect on salt-treate dro ads:
R a layer of salt on the brake disks or brakepads
can increase braking dis tances considerably,
or braking may happen on only one side
R maintain an especially large safe dis tance to
th eve hicle in front
To remo vethe la yer of salt:
R apply the brakes from time totime, paying
attention totraf fic conditions
R carefully dep ress the brake pedal at the end
of a journey and af terth est art of a new jour‐
ney
Ne w brake dis ksand brakepads
New brakepads and brake disks only reach their
optimal braking ef fect af ter appro ximately
10 0 km.
Un tilthen, compensate forth ere duced braking
ef fect by applying greater pressure tothe brake
pedal. For saf etyre asons, Mercedes-Benz recom‐ mends
that you on lyha ve brakepads and brake
disks which are appr ovedby Mercedes-Benz
ins talled on your vehicle.
Other brake disks or brakepads may compromise
th e saf ety of your vehicle.
Alw aysre place all brake disks and brakepads on
an axle at the same time. Alw aysfit new brake‐
pads when replacing brake disks.

Note s on aquaplaning
Aq uaplaning can take place once a cer tain
am ount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precipi‐
ta tion or in conditions in which aquaplaning may
occu r:
R reduce your speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
Note s on driving through water on roads
If th e maximum permissible height of thewate r is
exc eeded when ford ing, theve hicle can be dam‐
aged.
Obser vethefo llowing if you must drive thro ugh
wate r:
R thewate r level of standing water may not be

R you may drive no fasterthan walking pace
R vehicles tr avelling in front, or oncoming vehi‐

The braking ef fect of the brakes is reduced af ter

th e traf fic conditions until braking po wer has
been fully restored.
Note s on driving in mountainous areas
Ve hicles with diesel engines: the operating
saf ety of the diesel engine is guaranteed up toan
ele vation of 2,500 m ab ovesea le vel.Yo u may
exc eed this ele vation for a short time, e.g. in
mountainous terrain. Do not drive continuously at
ele vations ab ove2,500 m. Otherwise, you may
damage the diesel engine.
When driving in mountainous areas, no tethat
