systems
! ESP only functions prop erly if whe els with
the recommended tyre sizes are used
( =
page 399).
The engine must not be running if:
! the parking brake is being teste dusing a
dynamometer
! the vehicle is being towed with the front axle
ra ised
Appli cation of the brakes by ESP may otherw ise
des troy the braking system on therear axl e. i
Only use wheels with the recommended tyre
si zes. Only then wil lESP function properly. Activating
/deactivating ESP
It may be best to deactivate ESP in the
following situations:
! if snow chains are being used
! in deep snow
! on sand or gra vel When you deactivate ESP:
! ESP no longer improves driving stability
! the engine's torque isthen no longer
limited and the drive wheels could spin.
This res ults in a cutting action ofthe
spinning wheels for better grip
! traction control is still activated
! you can still brake with support from
ESP
i Thev warning lamp in the instrument
clus ter flashes if ESP isdeactivated and one or
mor ewhe els start to spin. ESP doe snot then sta-
bil ise the vehic le. G
Risk of accident Proceed as follows if the
vwarning lamp
in the speedometer flashes:
! under no circumsta nces should you
de activate ESP
! onlydepress the accelerator pedal as
far as necessary when pulling away
! donot keep your foot onthe ac celerator
while you are driv ing
! adapt your driving sty leto suit the road
and weather conditions
Otherwise ,the vehicle could begin toskid.
ESP cannot reduce the risk of an accident if
you drive too fast. G
Riskofaccident Activate ESP as soon as th
esituations
described above no longer apply. ESP will
ot he rwi sebe unable to stabilise the vehicle
if the vehicle starts to skid or when a wheel
spins. 209en_d2.

142 Controls in detail
Automatic transmission*
! Only press program selector switch 1
whe nthe selector lever isin position P,N or D.
6 Press program selector switch 1
repeatedly until the letter (S/C) for the
ge arshift program appears in the dis-
play (= page 141).
Se lect Cfor comfort mode:
! The vehicle pulls away and reverses
more gently unless full thrott leis
applied.
! Traction is increased. This means
that driving stability is increased on
slippery road sur faces, for example.
! The automatic transmission shifts
up sooner. This means that you
drive at lower engine speeds and
the wheels are less likely to spin. Accelerator pedal pos
ition
Your style of driving influences ho wthe
automatic transmission shifts gear:
! Little throttle:
early upshifts
! More throttle:
later upshi fts
Kickdown
Use kickd ownfor ma ximum accel eratio n:
6 Depress the accelerator pedal beyond
the pressure point.
The automatic transmission shifts to a
lower gear, depend ing on the engine
speed.
6 Release the accelerator pedal as soon
as the desired speed has been
reached.
The automatic transmission shifts back
up. Stopping
If you are only stopping briefly:
6
leave the selector lever in the drive
position
6 apply the brake to prevent the vehicle
from rolling away Manoeuvring
If you are manoeuvring in a tight space:
6
control the speed of the vehicle by
brak ing carefully
6 accelerate gently and smoothly Tr
ailertowing
6 Allow the engine to run inthe middle
engine speed range when dri ving on
uphill gradients.
6 Depending on the steepness of the
uphill or downhill gradient, shift down
to shift range 3or 2(
= page 140), even
if cruise control is acti vated. Driving

Controls in detail
Auxil iary heating /ventilation*
The auxiliary heating heats or ventilates
the vehicle interior to the temperature that
you have set using the temperature con-
trol.
You can set up to three sw itch-on times
using the operating system, one of whi ch
can be preselected ( =pa ge 126).
You can switch the auxiliary heating /
ve ntilation on and off immediately using:
! the sw itch on the centre console
(= page 176)
! the remote control ( =page 176)
In order to call up the Heater submenu in
the operating system directly:
6 Make sure that the ignition is set to 1
or 2.
6 Briefly press the auxiliary heating /
ventilation swi tch (
=pag e176). The auxiliary heating switches off automat-
ically after 50 minutes. You can have this
time changed. To have this done, please
visit a qua lified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
i The fuel tankmu st be at least a quarter full
to ensur eth at the auxiliary heating can operate. i
The auxiliary heatin g/ventilation automati-
cally adjusts to variat ions inthe outside temper-
ature and changes in wea ther. It is therefore
poss ible for the auxiliary heating to switch from
ventilation mode to heating mode or from heat-
ing mode to ventilation mode.
6 It is preferable to set the air condition-
ing to U.
i The auxi liary heating /ventilation can be
switched on ev en if theair conditioning isset to
manual. However, optim umcomfort wil lonlybe
achiev edif the air conditioning is set to U.
6 Set the interior temperature to the
desired value.
The auxiliary heating /ventilation
adjusts to the temperature set.
i Itis recommended that you set the temper-
ature to 22 °C. Auxiliary heati

Risk of fire and poisoning Ex
ha ust fumes are produced when the auxil-
iary heating is inoperation. For this reason,
switch off the auxiliary hea ting in confined
spaces which do not have an extraction sys-
tem, e.g. a gara ge.
Operating the auxiliary heating at filling sta-
tions or when refuelling your vehicle isprohib-
ited. For this reason, switch off the auxiliary
heati ngwhe nref uellin g. Be

6 Adapt your driving style to suit the
current road and weather conditions.
G Otherwise, there is a risk of an
accident. v
The yellow ESP warning lamp
flashes while you are dri ving. ESP or traction control is active because at
least one
ofthe wheels has reached its tyre
grip limit. Distroni c* is deactivated. 6
Adapt your driving style to suit the
current road and weather conditions.
6 Only depress the accelerator pedal as
much as necessary when pulling
awa y.
6 Ease off on the accelerator pedal if
you are driving.

tion software, depending on your vehi-
cle's equipment.

tance in hazardous situations, activat-
ed by the driver depressing the brake
pedal suddenly. The system boosts the
