Comfort drive program
The
Comfort drive program has the following
characteristics:
R comfort-oriented engine and transmission
settings.
R optimal fuel consumption resulting from the
automatic transmission shifting up sooner.
R the vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
pedal is depressed fully.
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.
Sport drive program The
Sport drive program has the following char-
acteristics:
R sporty engine and transmission settings.
R the automatic transmission shifts up later.
The fuel consumption possibly being higher
as a result of the later automatic transmission
shift points.
R the suspension exhibits sporty damping (vehi-
cles with AIRMATIC).
Drive program Sport Plus (Mercedes-
AMG vehicles) The
Sport Plus drive program has the following
characteristics:
R the vehicle exhibits particularly sporty driving
characteristics.
R the vehicle pulls away in first gear.
R the automatic transmission shifts up later.
The fuel consumption possibly being higher
as a result of the later automatic transmission
shift points.
R the suspension exhibits particularly firm
springing and damping settings (vehicles with AIRMATIC).
R the ECO start/stop function is deactivated, it
can, however, be activated again using the
ECO button (Y page 140). Individual drive program In the
Individual drive program, the following
properties of the drive program can be selected:
R the drive (engine and transmission manage-
ment)
R the transmission
R the suspension (vehicles with AIRMATIC)
R all vehicles (except Mercedes-AMG vehicles):

To select the gears in the Individualdrive pro-
gram permanently using the steering wheel pad- dle shifters, select the permanent manual gear-
shift program.
Information about configuring the Individual
drive program with the multimedia system can
be found in the Digital Operator's Manual. Manual gear shifting
General notes You can change gear yourself using the steering
wheel paddle shifters. The transmission must be
in position 005Bto 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.
To use manual shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the current
gear appears in the multifunction display
instead of transmission position 005B.
If manual gearshifting is deactivated, the gears
will be selected automatically. Automatic transmission

X
To shift up: pull steering wheel paddle
shifter 0044.
The automatic transmission shifts up to the
next gear.
All vehicles (except Mercedes-AMG vehi-
cles): if the maximum engine speed in the
gear currently engaged is reached and you
continue to accelerate, the automatic trans-
mission automatically shifts up to prevent
engine damage.
X To shift down: pull steering wheel paddle
shifter 0043.
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when coast-
ing.
If the engine were to exceed the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Shift recommendation The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display.
X When the corresponding gearshift recom-
mendation 0043appears in the multifunction display of the instrument cluster, shift to rec-
ommended gear 0044.
Upshifting (Mercedes-AMG vehicles) !
In manual mode, the automatic transmis-
sion does not shift up automatically 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. 0043

0044 Upshift indicator
Before the engine speed reaches the red area,
an upshift indicator will be shown in the multi-
function display. X When the UP UPmessage appears in the multi-
function display, pull on the right-hand steer- ing wheel paddle shifter.
Kickdown Mercedes-AMG vehicles:
kickdown is only
possible in the temporary setting.
X For maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed.
X Shift back up once the desired speed is
reached.
During kickdown, you cannot shift gears using
the steering wheel paddle shifters.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving. Automatic transmission

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. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapors. There is a risk of
fire and explosion.
Before you open the fuel filler cap or take hold of the pump nozzle, touch the metallic vehicle
body. This discharges any electrostatic
charge that may have built up.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
! Do not use gasoline to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! 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 adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
i Flexible Fuel vehicles can be recognized by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap. Please note that the warn-
ings about the risk of fire, explosion or injury
also refer to Flexible Fuel vehicles.

General notes To function properly, BlueTEC exhaust gas after-
treatment must be operated with the reducing
agent DEF. Adding DEF is one of the tasks per-
formed during maintenance. When the supply of DEF is almost used up, the
Check Additive See Operator's Manual
Check Additive See Operator's Manual
message is shown in the multifunction display.
If you drive the vehicle faster than 10 mph
(16 km/h), the Check Additive See Opera‐ Check Additive See Opera‐
tor's Manual
tor's Manual message goes out after approx-
imately one minute. Refueling
153Driving and parking Z

When the DEF supply drops to a minimum, the
Remaining Starts: 16
Remaining Starts: 16 message is shown in
the multifunction display.
If the Remaining Starts: 16
Remaining Starts: 16 message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is not
refilled, you will subsequently be unable to
start the engine.
X Add at least 2 gal (7.5 l)of DEF.
X Switch on the ignition for at least 60 seconds.
X Start the engine.
i The DEF range shown depends strongly on
the driving style and operating conditions.
The actual range can therefore deviate from
the calculated range. The DEF consumption is
between 1% and 5% of the fuel consumption.
i Have the DEF tank refilled at a qualified spe-
cialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. You can
obtain further information from an authorized
Mercedes-Benz Center or, if necessary, contact
Roadside Assistance (Y page 29).
If the outside temperature is below 12 ‡
(00F811 †), it may be difficult to top up. If DEF is
frozen and there is an active warning indicator, it
may not be possible to add DEF. Park the vehicle in a warmer place, e.g. in a garage, until DEF has become fluid again. It will then be possible to
add DEF again. Alternatively, have the DEF tank
refilled at a qualified specialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and DEF is available at any
authorized Mercedes-Benz Center.
Important safety notes DEF is a water-soluble fluid for the exhaust gas
aftertreatment of diesel engines. It is:
R Not poisonous
R Colorless and odorless
R Not flammable
When you open the DEF container, small
amounts of ammonia vapor may be released.
Ammonia vapors have a pungent odor and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence a burning sensation in your eyes, nose and throat. Coughing and watering of the eyes are
possible. Do not inhale ammonia vapors. Fill the DEF tank
only in well-ventilated areas.
DEF must not come into contact with your skin,
eyes or clothing and must not be swallowed.
Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the following:
R Rinse DEF from your skin immediately with
soap and water.
R If DEF comes into contact with your eyes,
immediately rinse them thoroughly with clean
water. Seek medical assistance without
delay.
R If DEF has been swallowed, rinse your mouth
out immediately. Drink plenty of water. Seek
medical assistance without delay.
R Change out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
! The vehicle must be parked on level ground
to fill the DEF tank. The DEF tank can only be filled as intended with the vehicle parked on a
level surface. This avoids false level readings.
Filling the tank is not permitted if the vehicle
is not parked on a level surface. There is a
danger of overfilling, which could result in
damage to components of the BlueTEC
exhaust gas aftertreatment.
! Immediately rinse off surfaces which come
into contact with DEF or remove DEF with a
damp cloth and cold water. If DEF has already crystallized, clean using a sponge and cold
water. DEF residue crystallizes after a short
period and contaminates the affected surfa-
ces. Furthermore, electrical components in
the vicinity may be damaged by DEF.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to the
fuel tank, this can lead to engine damage.
For further information on DEF, see
(Y page 386). 154

ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter- rain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious 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 G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
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 engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. You can obtain current information concerning
the servicing of your vehicle at any time from a
qualified specialist workshop. This could be an
overview of the maintenance work or any addi-
tional maintenance work, for example. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you
in achieving the most economical driving style

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: 0043
Acceleration
(evaluation of all accel-
eration processes):
R the outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds
R the outer area empties and the
inner area is gray: sporty acceler-
ation 0044
Coasting
(evaluation of all decelera-
tion processes):
R the outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
R the outer area empties and the
inner area is gray: frequent heavy
braking 0087
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
R the outer area empties and the
inner area is gray: fluctuations in
speed The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus fr. Start
Bonus fr. Start does not
indicate a fixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R load
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendations.
R drive the vehicle in the Comfortdrive pro-
gram.
On long journeys at a constant speed, e.g. on the highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. On lon- ger journeys, there are fewer changes. For more
marked changes, perform a manual rest
(Y page 233).
For further information on the ECO display, see (Y page 233). 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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lower gear in good time. This allows you to
take advantage of the engine's braking effect. Driving tips
161Driving and parking Z

This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a
drive wheel may not turn for some time, e.g.
on a slippery road surface. This could cause
damage to the drive train. This type of damage is not covered by the Mercedes-Benz war-
ranty.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Use the left-hand steering wheel paddle shifter
to shift into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control, the limiter or Active Distance Assist
DISTRONIC.
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads 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 the vehicle has
been washed or driven through deep water.
You then 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 vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt resi-
due 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.
Servicing the brakes !
The brake fluid level may be too low, if:
R if the red brake warning lamp lights up in
the instrument cluster and
R you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
! A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe- cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.
! Because ESP ®
is an automatic system, the
engine and ignition must be switched off
