Driving and parking

D Neutral
Do not shift the transmission to N
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
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:
shift the transmission to position N
if the vehicle is in danger of skid-
ding, e.g. on icy roads.
If you switch the engine off with the
transmission in position R or D , the
automatic transmission shifts to N
automatically.
! Rolling in neutral N can damage
the drive train.
: Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Driving tips
Changing gear
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D . This automatic gear shift-
ing behavior is determined by: R
the selected drive program R
the position of the accelerator pedal R
the road speed
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 Holding the vehicle stationary on uphill
gradients
G 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.
All vehicles (except Mercedes-AMG vehi-
cles): the Stop Vehicle Shift to P
Leave Engine Running display message
appears in the multifunction display. You will
only be able to continue your journey once the
clutch has cooled down and the display mes-
sage in the multifunction display has disap-
peared.

ual drive program M ( Y
page 168).
Rocking the vehicle free Shifting the transmission repeatedly between
gears D and R may help to free the vehicle if it
has become stuck in slush or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift back and forth
between transmission positions D and R ,
move the DIRECT SELECT lever up and down
past the point of resistance.

Manual gear shifting
General notes You can change gear yourself using the steer-
ing wheel paddle shifters. The transmission
must be in position D .
Depending on which paddle shifter is pulled,
the automatic transmission immediately
shifts into the next gear down or up, if per-
mitted.
Mercedes-AMG vehicles: to use manual
shifting, you have two options: R
temporary setting R
permanent setting
If you activate manual gearshifting, the mul-
tifunction display will show the current gear
instead of transmission position D .
If manual gearshifting is deactivated, the
gears will be selected automatically. Temporary setting X
To activate: shift the DIRECT SELECT lever
to position D . X
Pull steering wheel paddle shifter C or D .
Temporary setting will be active for a certain
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 ter-
rain. X
To deactivate: pull steering wheel paddle
shifter D and hold it in place.

Shifting gears
! Mercedes-AMG vehicles: 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
To shift up: pull steering wheel paddle
shifter D .
The automatic transmission shifts up to the
next gear.
All vehicles (except Mercedes-AMG
vehicles): if the maximum engine speed on
the currently engaged gear is reached and
you continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage. X
To shift down: pull steering wheel paddle
shifter C .
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when
coasting.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine dam-
age 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
Shift to recommended gear D according
to gearshift recommendation C when
shown in the multifunction display.
Upshifting (Mercedes-AMG vehicles)
! The automatic transmission does not shift
up automatically even when the engine lim-
iting 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 redAutomatic transmission 167

area of the tachometer. There is otherwise
a risk of engine damage.
Before the engine speed reaches the red area,
an upshift indicator will be shown in the mul-
tifunction display. X
Shift to recommended gear C when mes-
sage D is shown in the multifunction dis-
play.
Kickdown 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.
Mercedes-AMG vehicles: it is only possible
to use kickdown in temporary manual drive
program M . When manual drive program M is
permanently activated, kickdown is not pos-
sible.168

Parking
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-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
G 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.
! 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
the transmission must be in position P and
the transmission position display must
show P . R
the SmartKey must be removed from the
ignition lock. R
on uphill or downhill gradients, the front
wheels must be turned towards the curb. Parking 171

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. For this, you need to have selected
manual drive program M . This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program M is temporarily activated: the auto-
matic transmission may switch 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
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 air-
flow 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 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
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
In order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions. R
Carefully depress the brake pedal and the
beginning and end of a journey. R
Maintain a greater distance to the vehicle
ahead. Driving tips 177

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 immedi-
ately. Consult a qualified specialist work-
shop to arrange this.
! A function or performance test should
only be carried out on a 2-axle dynamom-
eter. If you wish to operate the vehicle on
such a dynamometer, please consult a
qualified specialist workshop in advance.
You could otherwise damage the drive train
or the brake system.
! As the ESP ®
system operates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0 or 1 in the ignition lock) if:R
the electric parking brake is tested on a
brake dynamometer (for a maximum of
ten seconds) R
the vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP ®
may seriously damage the brake system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
You can find a description of Brake Assist
(BAS) on ( Y
page 66).
Mercedes-Benz recommends that you only
have brake pads/linings installed on 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 vehi-
cle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake lining thickness You can measure the break pad/lining thick-
ness using a test gage. Color-coding (green or
red) on the test gage allows you to determine
whether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box.
