ESP
®
can moni tor and impr ovedriving stability
and traction in thefo llowing situations, within
ph ysical limits:
R When pulling away on wet or slippe rycar ria‐
ge wa ys.
R When braking.
R Vehicles with trailer hitch: in trailer opera‐
tion from speeds of 65 km/h, if theve hicle/
trailer combination begins tosw ay from side
to side.
R Instro ng side winds when you are driving
fa ster than 80 km/h.
If th eve hicle deviates from the direction desired
by the driver, ESP ®
can stabilise theve hicle by
inter vening in thefo llowing ways:
R One or more wheels are braked.
R The engine output is adap ted according to
th e situation.
ESP ®
is deactivated if theå ESP®
OFF warn‐
ing lamp lights up continuously in the instrument
clus ter. Obser
vethefo llowing points when ESP ®
is deac‐
tivated:
R Driving stability will no lon ger be impr oved.
R Vehicles with trailer hitch: stabilisation of
th eve hicle/trailer combination is no longer
active.
R Crosswind Assist is no longer active.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.
% When ESP ®
is deactivated, you are still assis‐
te dby ESP ®
when braking.
If th e÷ ESP®
wa rning lamp flashes in the
instrument clus ter,one or se veralve hicle wheels
has reached its grip limit:
R Adapt the driving style to suit the pr evailing
ro ad and weather conditions.
R Do not deactivate ESP ®
under any circum‐
st ances.
R Onlydepress the accelerator pedal as far as
is necessar y. 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.

R Warning and indicator lamps (→ page548)
R Displ aymessa ges (→ page 498)
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 ewa y.
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. Driving and parking

Ac
tive Parking Assist is cancelled if, among
ot her things, one of thefo llowing actions is car‐
ri ed out:
R You deactivate Parking Assist PARKTRONIC.
R You deactivate Active Parking Assist.
R You begin steering.
R You apply the parking brake.
R Vehicles with automatic transmission:
yo u en gage transmission position j.
R ESP ®
inter venes.
R You open the doors or theta ilgate while driv‐
ing.
Sy stem limitations
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 prematurely. &
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 Ifyo u are 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 Ifyo u ha veinstalled snow chains.
Ac tive Parking Assist may also display parking
spaces that are not suitable for parking, e.g.:
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 ave l in thefo llowing situations:
R If two parking spaces are located immedi‐
ately next toeach other.
R Ifth e parking space is directly next toa low

Driving and parking

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 459).
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 &
WARNING Risk of accident due toincor‐
re ct snow chain fitting
If yo ufit snow chains tothere ar wheels, the
snow chains may grind against theve hicle
body or chassis components.
This could cause damage totheve hicle or
th e tyres. #

Obser
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.
% You can permanently limit the maximum
ve hicle speed for driving with winter tyres
(→ page 200).
% You can deactivate ESP ®
to pull away
( → page 189). This allo ws the wheels to
spin, achieving an increased driving forc e. Ty

s on tyre pressure &
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. #
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 #
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. &
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. #
