Manual gear shifting
General notes
You can change gear yourself using the steering wheel paddle shifters. The transmission must be
in position hto do this.
Depending on which steering wheel paddle
shifter is pulled, the automatic transmission
immediately shifts into the next gear down or
up, if permitted. Mercedes-AMG vehicles:
to use manual shift-
ing, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position h.
If manual gearshifting is deactivated, the gears
will be selected automatically.
Temporar ysetting
XTo activate: shift the DIRECT SELECT lever to
position h.
XPull steering wheel paddle shifter :or;.
Temporary setting will be active for acertain
amount of time. Under certain conditions the
minimum amount of time is extended, e.g. in the case of lateral acceleration, during an overrun
phase or when driving on steep terrain.
XTo deactivate: pull steering wheel paddle
shifter ;and hold it in place.
or
XUse the DIRECT SELECT lever to switch the
transmission position.
or
XAll vehicles (except Mercedes-AMG vehicles):
use the DYNAMI CSELECT button to change
the drive program.
Mercedes-AMG vehicles: use the DYNAMIC
SELECT controller to change the drive pro-
gram.

Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RRemove roof racksw hen they are not needed.
RWarm up the engineatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main- tenance Booklet or by the servicei
nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aqualified specialist
workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenance Booklet.
