It may be best
todeactivate ESP ®
in thefo llow‐
ing situations:
R When using snow chains.
R In deep sn ow.
R On sand or gr avel.
% Spinning the wheels results in a cutting
action, which enhances traction.
If th e÷ ESP®
wa rning lamp lights up continu‐
ousl y,ESP ®
is not available due toa malfunction. Obse
rveth efo llowing information:
R Warning and indicator lamps (/ page 581)
R Display messages (/ page 527)
ETS/4ETS (Electronic Traction Sy stem)
ETS/4E TStraction control is pa rtof ESP ®
and
makes it possible topull away and accelerate on
a slippe rycar riag ew ay.
ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they spin. R
More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
The drive programs enable ESP ®
to adapt todif‐
fe re nt we ather and road conditions as well as
th e driver's prefer red driving style. You can
select the drive prog rams using theDY NA MIC
SELECT switch (/ page166). 194

Sy stem limits
Objects located abo veor below the de tection
ra nge of Active Parking Assist are not de tected
when the parking space is being measured.
These are also not take n into account when the
parking manoeuvre is calculated, e.g. overhang‐
ing loads, overhangs or loading ramp s of lor ries
or the boundaries of parking spaces. In some cir‐
cums tances, Active Parking Assist may therefore
guide you into the parking space prematurel y. &
WARNING Risk of accident due to
objects located abo veor below the
de tection range of Active Parking Assist
If th ere are objects abo veor below the
de tection range, thefo llowing situations may
arise:
R Active Parking Assist may steer too ear ly.
R Vehicles with automatic transmis‐
sion: Thevehicle may not stop in front of
th ese objects.
This could cause a collision. #
Inthese situations, do not use Active
Pa rking Assist. Sn
owfa ll or heavy rain may lead toa parking
space being measured inaccuratel y.Pa rking
spaces that are partial lyoccupied bytrailer
dr aw bars might not be identified as such or be
measured incor rectly. Only use Active Parking
Assist on le vel, high-grip ground. Do not
useActive Parking Assist in thefo llowing
situations:
R Inextreme weather conditions such as ice,
pac ked snow or in heavy rain.
R When transporting a load that pr otru des
be yond theve hicle.
R Ifth e parking space is on a steep downhill or
uphill gradient.
R When snow chains are fitted.
Ac tive Parking Assist may also display parking
spaces that are not suitable for parking, e.g. the
fo llowing:
R Parking spaces where parking is prohibited.
R Parking spaces on unsuitable sur faces.
Ac tive Parking Assist will not assist you with
parking spaces at right angles tothe direction of
tr av el in thefo llowing situations:
R If two parking spaces are located immedi‐
ately next toeach other.
R Ifth e parking space is immediately next to a

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 &
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. #
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 (/ page 486).
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

shop. The new wheel must ha vethe
cor rect dimensions. The collapsible spa
rewheel is an emer gency
wheel which is only suitable for use for a limi ted
period of time and in a restricted manner in the
eve nt of a flat tyre (e.g. until the nearest work‐
shop).
The tyre side walls are folded when in transpo rt
mode. Before use, the collapsible spare wheel
has tobe inflated with the accompanying com‐
pressor.
Check the tyre pressure of the collapsible spare
wheel once fitted. Co rrect the pressure as nec‐
essar y.
The maximum permissible speed with a collapsi‐
ble spare wheel fitted is 80 km/h. Do not
fit snow chains with the collapsible spare
wheel.
Re place the collapsible spare wheel af ter six
ye ars at the latest, rega rdless of wear.

fi tted, the tyre pressure loss warning sy stem
cann otfunction reliabl y.Only restart the sys‐
te m again when the collapsible spare wheel
has been replaced with a new wheel.
Ve hicles with a tyre pressure monitoring
sy stem: if a collapsible spare wheel is fitted
th e tyre pressure monitoring sy stem cann ot
function reliably. For a few minutes af ter an
emergency spare wheel is fitted, the sy stem
may still display the tyre pressure of the
