MERCEDES-BENZ C-CLASS SALOON 2018 Owners Manual

Note
s on noise or unusual handling charac‐
te rist ics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling
ch aracteristics. If youfind no signs of damage,
ha ve the tyres and wheels checked at a qualified
specialist workshop. Note
s onregular lyinspecting wheels and
tyres 000A
WARNING Risk of accident from dam‐
aged tyres
Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. 0007
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (0013 page449).
R Visually inspect tyres and wheels for dam‐
age.
R Check theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.
R Visual check of the tyre tread dep thand the
tyre contact su rface across the entire width.
The minimum tread dep thfor summer tyres
is 3 mm and for winter tyres 4 mm. Note
s on snow chains 000A
WARNING Risk of accident due toincor‐
re ct snow chain fitting
If yo u ha vefitted snow chains tothe front
wheels, the snow chains may drag against
th eve hicle body or chassis components.
This could cause damage totheve hicle or
th e tyres. 0007
Neverfit snow chains on the front
wheels. 0007
Only fit snow chains on there ar wheels

vethefo llowing no tes when using snow
ch ains:
R Snow ch ains are on ly permissible for cer tain
wheel/tyre combinations. You can obtain
information about this from a Mercedes-Benz
Service Cent re.
R For saf etyre asons, on lyuse sn ow chainsthat
ha ve been specifically appr ovedfo ryo ur

with the same quality standard.
R If sn ow ch ains are fitted, the maximum per‐
missible speed is 50 km/h.
R Vehicles with Active Park ing Assis t:do
not use Active Parking Assist when snow
ch ains are fitted.
R Vehicles with le vel control: if snowchains
are fitted, only drive at raised vehicle le vel.
0009 You can permanently limit the maximum
ve hicle speed for driving with winter tyres
(0013 page218).
0009 You can deactivate ESP ®
to pull away
( 0013 page 207). This allo ws the wheels to

s on tyre pressure 000A
WARNING Risk of accident due toinsuf‐
fi cient or excessive tyre pressure
Underinfla ted or overinfla ted tyres pose the
fo llowing risks:
R The tyres may bur st, especially as the
load and vehicle speed increase.
R The tyres may wearexc essively and/or
une venly, which may greatlyimpair tyre
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. 0007
Comply with there commended tyre
pressure and check the tyre pressure of
all tyres including the spare wheel regu‐
larly:
R at least once a month
R when the load changes R
before embarking on a lon ger journey
R if operating conditions change, e.g. off-
ro ad driving 0007
Adjust the tyre pressure as necessar y. Driving wi
thtyre pressu rethat is too high or too
low can:
R Sho rten the service life of the tyres.
R Cause increased tyre damage.
R Adversely af fect driving characteristics and
th us driving saf ety, e.g. due toaquaplaning. 000A
WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedl y,the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. 0007

Check whe ther the wheel or valve has a
leak. 0007
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 (0013 page 450).
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 th ree 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.

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
(0013 page 451).
If th ere is a subs tantial pressure loss or if the

Af ter a change in tyre pressure, a wheel rotation
or a tyre change, or if you ha verefitted wheels
or tyres, the tyre pressure loss warning sy stem

The tyre pressure loss warning sy stem does not
re place the need toregular lych eck the tyre

The sy stem may be impaired or may not function
particularly in thefo llowing situations:
R incor rectly set tyre pressure
R sudden pressure loss caused, forex ample,
by afo re ign object penetrating the tyre
R steady pressure loss in se veral tyres The sy
