helps youto reduce fuel consum ption.
Glide mode is characterised bythefo llowing:
R the combustion engine is disconnected from

R the transmission position display his
shown in green.
R vehicles with 48 V on-board electrical

bustion engine can be switched off. All of the
ve hicle functions remain active.
Glide mode is activated if thefo llowing condi‐
tions are me t:
R drive program ;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 hitched up tothe trailer
hitch, and no bicycle rack fitted.
R you do not depress the accelera tor or brake
pedal (e xcept for light brake applications).
% Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the

Glide mode is deactivated again if one of the
conditions is no longer met.

WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs the handling characteristics and is
not suitable for higher speeds. #
Adapt your driving style according lyand
drive carefull y. #
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. #
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h.
* NO
TEStaining from leaking tyre sealant Af
ter use, excess tyre sealant may leak out
from thefilling hose. #
Therefore, place thefilling hose in the
plastic bag that con tained the TIREFIT
kit. +
ENVIRONMEN

pollution caused byenvironmen tally ir re‐
sponsible disposal Ty
re sealant contains polluta nts. #
Have the tyre sealant bottle disposed of
professionall y,e.g. at a Mercedes-Benz
Service Centre. #
Stow th e tyre sealant bottle and the tyre
inflation compressor. #
Pull away immediatel y. #
Stop driving af ter appro ximately ten minu tes
and check the tyre pressure using the tyre
inflation compressor.
The tyre pressure must now be at least
13 0 kPa (1.3 bar/19 psi). &
WARNING Risk of accident due tothe
specified tyre pressure not being
attained
If th e specified tyre pressure is not reached,
th e tyre is too badly damaged. The tyre seal‐
ant cannot repair the tyre in this ins tance. The braking and driving
characteristics may
be great lyimpaired. #
Do not continue driving. #
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. Breakdown assis
tance 313

To
o low a tyre pressure can lead tothe tyres
bur sting. #
Examine the tyres forfo re ign objects. #
Check whe ther the tyre has a puncture
or theva lve 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 329).
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.
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. The
vehicle's tyres heat up when driving. As the
te mp erature of the tyres increases, so too does
th e tyre pressure.
Ve hicles with tyre pressure monitoring sys‐
te ms: you can also see the tyre pressure in the
driver's displa y.
Note s on trailer operation
Alw ays inflate there ar axle tyres tothere com‐
mended tyre pressures on the tyre pressure
ta ble for increased load. Ty
re pressure table The tyre pressure
table is on the inside of the
fuel filler flap. If one or more tyre sizes precede a tyre pres‐
sure, thefo llowing tyre pressure information is
only valid forth ose tyre sizes and their respec‐
tive load condition.
If th e preceding tyre sizes are complemented by
th e+ symbol, the tyre pressure information
fo llowing sho wsalternative tyre pressures. Fuel
consum ption may then increase slightl y. Wheels and tyres
