4MATIC+: you can also preset manual mode for
drive program I . To do so, select the M (Manual)
setting when configuring the transmission.
When driving in drive program I , you perma-
nently shift the gears manually using the steer-
ing wheel paddle shifters.
Information about configuring drive program I
with the multimedia system can be found under "DYNAMIC SELECT" in the vehicle's Digital
Operator's Manual.
Shifting gears X
To shift up: pull steering wheel paddle
shifter D .
The automatic transmission shifts up to the
next gear.
If the maximum engine speed in the gear cur-
rently engaged is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage (except Mercedes-AMG vehicles).
Mercedes-AMG vehicles: if the temporary
setting has been activated and you continue
to accelerate when the maximum engine
speed has been reached, the automatic trans-
mission automatically shifts up. If the perma-
nent setting is activated, the automatic trans-
mission does not shift up automatically even
when the engine limiting speed for the current
gear is reached. Observe the protection
against reaching the overrevving range on the
multifunction display. Always make sure that
the engine speed does not reach the red area
of the tachometer. X
To shift down: pull steering wheel paddle
shifter C .
The automatic transmission shifts down to
the next gear.
Automatic down shifting occurs when coast-
ing.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine damage
by not shifting down.Automatic transmission 153

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 C appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear D .
Protection against reaching the over-
revving range (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. Before the engine speed reaches the red area,
an upshift indicator will be shown in the multi-
function display. X
When message C appears on the multifunc-
tion display, pull the right-hand steering
wheel paddle shifter.
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.
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: kickdown is only
possible in the temporary setting.154

Problems with the transmission Problem
Possible causes/consequences and P Solutions
The transmission has
problems shifting gear. The transmission is losing oil. X
Have the transmission checked at a qualified specialist workshop
immediately.
The acceleration ability
is deteriorating.
The transmission no lon-
ger changes gear. The transmission is in emergency mode.
It is possible to shift to a gear and reverse gear only. X
Stop the vehicle. X
Shift the transmission to position ] .X
Switch off the engine. X
Wait at least ten seconds before restarting the engine. X
Shift the transmission to position [ or ^ .
If [ is selected, the transmission only shifts to one gear; if ^ is
selected, the transmission shifts to reverse gear. X
Have the transmission checked at a qualified specialist workshop
immediately.
Transfer case This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
! Performance tests may only be carried out
on a 2-axle dynamometer. The brake system
or transfer case could otherwise be damaged.
Contact a qualified specialist workshop for a
performance test.
! Since ESP ®
engages automatically, the igni-
tion must be switched off (the SmartKey or
Start/Stop button must be in position Z or
G ) if R
the electrical parking brake is being tested
using a dynamometer R
the vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC)
Otherwise, the brake system can be dam-
aged.
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as
doing so will damage the transmission. Refueling
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 Refueling 155

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 buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. otherwise electrostatic charge
could build up again.
! 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 from
the fuel can.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.

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 driv-
etrain 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 ] and
the SmartKey must be removed from the igni-
tion lock. R
the front wheels must be turned towards the
curb on steep uphill or downhill gradients. R
the empty vehicle must be secured at the
front axle with a wheel chock or similar, for
example, on uphill or downhill gradients. R
on uphill or downhill gradients the laden vehi-
cle must also be secured at the rear axle, for
example with a wheel chock or similar object. Switching off the engine

G WARNING
The automatic transmission switches to neu-
tral position N when you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
