0050Solutions The transmission has
problems shifting gear. There is a malfunction in the transmission.
The transmission no longer shifts into the next gear.
X
Have the transmission checked at a qualified specialist workshop
immediately. The acceleration ability
is deteriorating.
The transmission no lon-
ger shifts into all of the
gears. A sub-transmission has failed.
The smoothness of the gear change is restricted.
X Have the transmission checked at a qualified specialist workshop
immediately. Refueling
Important safety notes
G
WARNING
Fuel is highly flammable. Risk of fire and
explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off the auxiliary heating. 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
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.
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 fromthe fuel can. Refueling

X Consult a qualified specialist workshop. 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.
! If the engine speed is too high or the vehicle
is in motion, do not shift the automatic trans- mission directly from 005Bto005E, from 005Eto005B
or directly to 005D.
Do not open the driver's door while the vehi-
cle is in motion. At low speeds in transmission Parking

Checking coolant level G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following. G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
The cooling system is pressurized, particularly when the motor is warm. If you open the cap, you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear protective gloves and protective
eyewear when opening. Open the cap slowly
to release pressure.
! Before starting your journey, make sure that
all engine covers are installed. Otherwise, the engine can be damaged, e.g. through over-
heating. Example
X Park the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Select key position 0048with the Start/Stop
button.
X Check the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
X Select key position 0092with the Start/Stop
button.
X Remove engine cover 0043upwards on both
sides.
X Slowly turn cap 0044half a turn counter-clock-
wise to allow excess pressure to escape.
X Turn cap 0044further counter-clockwise and
remove it.
If the coolant is at the level of the marker bar in the filler neck when cold, there is enough
coolant in coolant expansion tank 0087.
If the coolant level is approximately 0.6 in
(1.5 cm) above the marker bar in the filler
neck when warm, there is enough coolant in
coolant expansion tank 0087.
X If necessary, add coolant that has been tested
and approved by Mercedes-Benz. Engine compartment
