A
Neutral
Do not shift the transmission to
N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
Releasing the brakes will allow you
to move the vehicle freely, e.g .to
push it or tow it.
If ESP ®
is deactivated or faulty:
only shift the transmission to posi-
tion Nif the vehicle is in danger of
skidding, e.g. on icy roads.
! Rolling in neutral Ncan lead to
damage to the transmission. 7
Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Changing gear
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D.This automatic gearshift-
ing behaviouri s determined by:
R a shift range restriction, if selected
R the selected drive program (Y page 163)
R the position of the accelerator pedal
R the road speed Driving tips
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts
AMG vehicles When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch function reduces load change reactions and is condu-
cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.
Kickdown
Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Trailer towing X
Drive in the middle of the engine speed
range on uphill gradients.
X Shift down to shift range 3or
2(Y page 165) depending on the uphill or
downhill gradient, even if cruise control or
SPEEDTRONIC is activated. Program selector button
General notes The program selector button allows you to
choose between different driving character-
istics.
Example: program selector button Automatic transmission
163Driving and parking Z

on vehicles with automatic transmission,
select shift range
1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion. Limited braking performance on salt-
treated roads G
WARNING
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain a greater distance to the vehicle
ahead and drive with particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linings G
WARNING
New brake pads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
for the reduced braking effect by applying
greater pressure when braking. This also
applies after the brake discs or the brake
pads/linings have been replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety. 176
Driving tipsDriving and parking

At the onse
tofwinter, have your vehicle win-
terproofed at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre.
Observe the notes in the "Winter operation"
section (Y page 359).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
page 359).
Slippery road surfaces G
WARNING
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission :engage
neutral.
X Vehicles with automatic transmission: shift
the transmission to position N.
X Try to bring the vehicl eunde rcontrol by
using corrective steering.
i For more information on driving with
snow chains, see (Y page 360).Driving systems
Cruise control
Important safety notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. You must
select a low gear in good time on long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer. On vehicles
with automatic transmission, select shift
range 1,2or 3.B y doing so, you will make use of the braking effec
tofthe engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at a constant speed (e.g. heavy traffic
or winding roads). You may otherwise
cause an accident.
R on slippery roads. The drive wheels may
lose their grip when braking or accelerating
and the vehicle may skid.
R when there is low visibility, e.g. due to fog,
heavy rain or snow.
Cruise control lever You can operate cruise control and variable
SPEEDTRONIC with the cruise control lever.178
