Mercedes-AMG
vehicles: observeth e no tes in
th e Supplement. Otherwise, you may failto rec‐
ognise dangers.
Wi th an anticipatory driving style, Glide mode
helps youto reduce fuel consum ption.
Glide mode is characterised bythefo llowing:
R the combustion engine is disconnected from
th e driv etra in and the engine continues to
ru n in neutral.
R the transmission position his displa yed in
green in the multifunction displa y.
R vehicles with a 48 V on-board electrical
sy stem (EQ Boost technology): the com‐
bustion engine is switched off depending on
th e driving situation. All of theve hicle func‐
tions remain active.
Glide mode is activated if thefo llowing condi‐
tions are me t:
R drive prog ram ; is selected.
R the speed is within a suitable range. R
thero ad's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R there is no trailer coupled tothe trailer hitch,
and no bicycle rack fitted.
R you are no lon ger depressing the accelera tor
or brake pedal.
% Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the
drive prog ram =.
Glide mode is deactivated again if one of the
conditions is no longer met.
Glide mode can also be pr evented bythefo llow‐

WARNING Risk of accident due tothe
specified tyre pressure not being ach‐
ie ved
If th e specified tyre pressure is not achie ved
af te r a brief drive, the tyre is too badly dam‐
aged. The tyre sealant cannot repair the tyre
in this ins tance.
Dama ged tyres and a tyre pressure that is
to o low can significantly impair braking and
handling characteristics. #
Do not drive on. #
Consult a qualified specialist workshop. Countries
that ha veMercedes-Benz
Service24h: you will find a sticke r with thete le‐
phone number, e.g. on the B‑pillar on the driver's
side. #
Cor rect the tyre pressure if it is still at least
13 0 kPa (1.3 bar/19 psi). See the tyre pres‐
sure table on the fuel filler flap forva lues. #
Toincrease the ty repressure: switch on
th e tyre inflation compressor. #
Toreduce the tyre pressure: press pres‐
su re re lease button 1next tomanome ter
2 . #
When the tyre pressure is cor rect, unscr ew
th efilling hose from theva lve of the sealed
tyre. #
Screw theva lve cap onto theva lve of the
sealed tyre. #
Pull the tyre sealant bottle out of the tyre
inflation compressor.
The filling hose stay s on the tyre sealant bot‐
tle. #
Drive tothe nearest qualified specialist work‐
shop and ha vethe tyre, tyre sealant bottle
and filling hose replaced there. Batte

WARNING Risk of an accident due to
wo rkcar ried out incor rectly on the bat‐
te ry
Wo rkcar ried out incor rectly on the battery
can, forex ample, lead toa short circuit. This
can lead tofunction restrictions in saf ety-re l‐
eva nt sy stems, e.g. the lighting sy stem, ABS
(anti-lock braking sy stem) or ESP ®
(Elec‐
tronic Stability Prog ram). The operating
saf ety of your vehicle may be restricted.
Yo u could lose cont rol of theve hicle in the
fo llowing situations:
R when braking
R intheeve nt of ab rupt steering manoeu‐
vres and/or when theve hicle's speed is
not adap tedto thero ad conditions 420
Breakdown assis tance

#
Check whe ther the wheel or valve has a
leak. #
Ifyo u are unable torectify the damage,
conta ct aqualified specialist workshop. Information on
there commended tyre pressure
fo rth eve hicle's factor y-fitted tyres can be found
on the tyre pressure table on the inside of the
fuel filler flap (→ page 437).
Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure.
Ve hicles with a tyre pressure monitoring sys‐
te m: you can also check the tyre pressure using
th e on-board computer.
Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least thre e hours.
R The vehicle has tr avelled less than 1.6 km.
A rise in the tyre temp erature of 10°C increases
th e tyre pressure byappr ox.10 kPa (0.1 bar/ 1.
5 psi). Take this into account when checking
th e tyre pressure of warm tyres.
Tr ailer operation no tes
Alw ays inflate there ar axle tyres tothere com‐
mended tyre pressures on the tyre pressure

table is on the inside of the
fuel filler flap. The tyre pressure
table sho ws there commended
tyre pressure for all tyres appro vedfo rth is vehi‐
cle. The recommended tyre pressures apply for
cold tyres under various operating conditions,
i.e. loading and/or speed of theve hicle.
If one or more tyre sizes precede a tyre pres‐

These tyre pressures may impr oveyour vehicle's

increase slightl y.
The load conditions "partially laden" and "fully
laden" are defined in theta ble for dif fere nt num‐
be rs of passengers and amounts of luggage. The
actual number of seats may dif fer from this.

tem
The sy stem checks the tyre pressure and the
tyre temp erature of the tyres fitted totheve hicle
by means of a tyre pressu resensor.
New tyre pressure sensors, e.g. in winter tyres,
are automatically taught-in during thefirs t jour‐
ney they are used. The tyre pressure and
the tyre temp erature
appear in the multifunction display
(→ page 438).
If th ere is a subs tantial pressure loss or if the
tyre temp erature is excessive, you will be
