Drive program E(drive program Con AMG
vehicles) is characterized by the following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
Drive program Sis characterized by the fol-
lowing:
R sporty engine and transmission settings
R the vehicle pulling away in first gear
R the automatic transmission shifting up
later
R the fuel consumption possibly being higher
as a result of the later automatic transmis- sion shift points 144

Shift ranges
Introduction When the automatic transmission is in posi-
tion
D, it is possible to restrict or derestrict
the shift range.
The shift range selected is shown in the mul- tifunction display. The automatic transmis-
sion shifts only as far as the selected gear.
Setting the shift range is not possible on AMG
vehicles.
Driving situations =
You can use the engine's braking
effect
5
The braking effect of the engine can
be utilized on downhill gradients or
when driving:
R on steep mountain roads
R in mountainous terrain
R in arduous conditions 4
The braking effect of the engine can
be utilized on extremely steep
downhill gradients and long down-
hill stretches. Restricting the shift range
X
Pull the left-hand steering wheel paddle
shifter (Y page 144).
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto- matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel- erate, the automatic transmission shifts upin order to prevent the engine from over-
revving, even if the shift range is restricted. Derestricting the shift range X
Pull the right-hand steering wheel paddle
shifter (Y page 144).
The automatic transmission shifts up one
gear and restricts the shift range to the rel-
evant gear.
Clearing the shift range restriction X
Pull and hold the right-hand steering wheel
paddle shifter (Y page 144) untilDis shown
again in the multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range X
Pull the left-hand steering wheel paddle
shifter (Y page 144) and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this, the automatic transmission shifts down one or more
gears.
i The automatic transmission cannot shift
down beyond second gear. To shift to first
gear, you have to pull the left steering
wheel paddle shifter. Manual drive program
General information The manual drive program is only available on
AMG vehicles. In manual drive program M,
you can permanently change gear yourself by using the steering wheel paddle shifters. The
transmission must be in position D. The gear
currently selected and engaged is shown in
the multifunction display.
Manual drive program Mdiffers from drive
programs Eand Swith regard to spontaneity,
responsiveness and smoothness of gear
changes. Automatic transmission

Upshifting !
In manual drive program
M, the automatic
transmission does not shift up automati-
cally even when the engine limiting speed
for the current gear is reached. When the
engine limiting speed is reached, the fuel
supply is cut to prevent the engine from
overrevving. Always make sure that the
engine speed does not reach the red area of
the tachometer. There is otherwise a risk of
engine damage. X
If corresponding gearshift recommenda-
tion :appears in the multifunction display
on the instrument cluster, pull on the right- hand steering wheel paddle shifter
(Y page 144).
The automatic transmission shifts to rec-
ommended gear ;.
Downshifting X
Pull the left-hand steering wheel paddle
shifter (Y page 144).
The automatic transmission shifts down to
the next gear.
i If you slow down or stop without shifting
down, the automatic transmission auto-
matically shifts down. Selecting the optimal gear for maxi-
mum acceleration X
Pull the left-hand steering wheel paddle
shifter until the transmission selects the
optimum gear according to the speed.

Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling. G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children. If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
! Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the
wrong fuel result in damage to the fuel sys-
tem and engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify Refueling
147Driving and parking Z

a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, pressure may build up in the fuel tank. This could cause fuel to
spray out when the fuel pump nozzle is
removed. There is a risk of injury. The fuel
tank is full when the fuel pump nozzle first
switches off. End the refueling process.

WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury. When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.

WARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's concentration must always be directed pri-
marily at road traffic. For your own safety and that of others, we recommend that you stop
the vehicle at a safe place and in accordancewith the traffic conditions before making or
accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate COMAND (Cockpit Management and Data System) in compliance with all legal
requirements and when the road, weather and traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance of 44 ft (approximately 14 m)a second when
it is traveling at only 30 mph (approximately
50 km/h). G
