WARNING
If the clutch overheats, the electronic man-
agement
system is automatically deactivated. This interrupts the power transmission. The
vehicle may, for example, roll backwards on
gradients. There is a risk of an accident.
Never hold the vehicle stationary on uphill
gradients by depressing the accelerator.
The

clutch may overheat if you hold the vehi-
cle stationary on uphill gradients by depress-
ing the accelerator pedal. If the clutch over-
heats, a warning tone sounds.

In drive program M, you can change gear
yourself using the steering wheel gearshift
paddles.
If
you pull the left or right steering wheel gear-
shift paddle when in automatic drive program
E (drive program C on AMG vehicles) or S, the
automatic transmission shifts into drive pro-
gram M for a limited time. Depending on
which gearshift paddle is pulled, the auto-
matic transmission immediately shifts into
the next gear down or up.
AMG vehicles: you can activate drive pro-
gram M RACE START (Y page 181) using the
steering wheel gearshift paddles.
i You can only change gear with the steer-
ing wheel gearshift paddles when the trans-
mission is in position D.
i For further information on the manual
drive program, see ( Y page 156).Automatic drive program
Drive program E (drive program C on AMG
vehicles) is characterised by the following:
R comfort-oriented engine 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 accel-
erator 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 S is characterised by the fol-
lowing:
R sporty engine settings.
R the automatic transmission shifting up
later.
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos-
sibly being higher. Manual drive program
Introduction In manual drive program
M, you can change
gear yourself by using the steering wheel
gearshift paddles. For this, the transmission
must be in position D. The gear currently
selected and engaged is shown in the multi-
function display.
Manual drive program M differs from drive
programs E (drive program C on AMG vehi-
cles) and S with regard to spontaneity,
responsiveness and smoothness of gear
changes. Gear Driving situations

Important safety notes
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.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry
grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift

the automatic transmission out of park
position P or shift manual transmission into
neutral
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 key
with you and lock the vehicle. Never leave
children unattended in the vehicle. !
Always secure the vehicle correctly
against

rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R on vehicles with manual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmission must be in position P and
the transmission position display must
show P in the multifunction display.
R the key must be removed from the ignition
lock.
R on uphill or downhill gradients, the front
wheels must be turned towards the kerb. Switching off the engine
Important safety notes G
WARNING

dynamic changes in the bars at the start of
a
journey. During a prolonged driving time,
these changes are smaller. For more
dynamic changes, perform a manual reset.
For further information on the ECO display,
see ( Y page 212). Braking
Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This

increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and

steep downhill gradients. Take particular
note of this when driving a laden vehicle and
when towing a trailer. For vehicles with auto-
matic transmission, you need to have selec-
ted manual drive program M(Y page 156).
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 prevent the
vehicle from gaining speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
i Briefly depressing the accelerator pedal
on downhill gradients while the manual
drive program M is temporarily activated
(vehicles with automatic transmission): the
automatic transmission may switch back to
the last active automatic drive program E
or S. The automatic transmission may shift to a higher gear. This can reduce the
engine's braking effect.
Heavy and light loads G
WARNING
The braking system can overheat if you leave
your foot on the brake pedal while driving.
This

increases the braking distance and could
even cause the braking system to fail. There
is a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do
not park the vehicle immediately. Drive on for
a short while. This allows the airflow 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, paying attention to traffic con-
ditions. This improves the grip of the brakes.
Wet road surfaces If you have driven for a long time in heavy rain
without

braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after a car wash or
after driving through deep water.
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. 166
Driving tips
Driving and parking

Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
R
Brake
occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
New brake pads/linings New and replaced brake pads and discs only
reach

their optimum braking effect after sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brake pedal.
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. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth
on

the road surface, there is a danger of aqua-
planing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts and
brake carefully. Driving on flooded roads !
Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam-
age

the engine, the electronics or the trans-
mission.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permissible fording depth in
still water is 25 cm
R you should drive no faster than walking
pace Winter driving
General notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This

increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such

as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
a window on the side of the vehicle that is not
facing into the wind. Driving tips
