Shifting up (AMG vehicles)
!In manual drive programM, the automatic
transmission 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.

Transfer case
!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.
!Because ESP®is an automatic system,
the engine and ignition must be switched
off (SmartKey in position0or1or Start/
Stop button in position0or1) when the
electric parking brake is being tested on a
brake dynamometer (maximum
10 seconds).
Braking triggered automatically by ESP®
may seriously damage the brake system.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always
transmitted to both axles.
Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and
explosion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
GWARNING
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.
182Refueling
Driving and parking

If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance
without delay.
RIf fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
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.
GWARNING
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 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.
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 refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
Do not get into the vehicle again during the
refueling 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.

fuel quality in the printed Operator's Manual

DEF (BlueTEC vehicles only)
Important notes on use
To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent DEF. Adding DEF is one of the
tasks performed during maintenance. Under
normal operating conditions, a tank of DEF
lasts until the next service due date.
When the supply of DEF is almost used up,
theCheck Additive See Operator'sCheck Additive See Operator's
ManualManualmessage is shown in the
multifunction display.
If you drive the vehicle faster than 10 mph
(16 km/h), theCheck Additive SeeCheck Additive See

approximately one minute.
When the supply of DEF is down to a reserve
of approximately 1 gal (3.8 l) theRefillRefill

message is shown in the multifunction
display.
When the DEF supply drops to a minimum, the

in the multifunction display.
If theRefill AdBlue/DEF No Start inRefill AdBlue/DEF No Start in
XXXX kmXXXX kmmessage is shown in the
multifunction display, you can still drive the
vehicle over the distance shown. If DEF is not
refilled, you will subsequently beunable to
start the engine. If theRefill AdBlue/Refill AdBlue/
DEF Eng. Start Not PossDEF Eng. Start Not Possmessage
appears in the multifunction display and the
engine does not start, you must add DEF.
XAdd at least 1 gal(3.8l) of DEF.
XSwitch on the ignition for at least 60
seconds.
XStart the engine.
iHave the DEF tank refilled at a qualified
specialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
an authorized Mercedes-Benz Center with
any questions or, if necessary, contact
Roadside Assistance (Ypage 25).
If the outside temperature is below 12 ‡
(

water. Seek medical assistance without
delay.
RChange 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
aftertreatment 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.
!Rinse surfaces that have come into
contact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF
residues crystallize after time and
contaminate the affected surfaces.
!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
(Ypage 448).
You will find further information on DEF in the
printed Operator's Manual under "Technical
data".

Parking
Important safety notes
GWARNING
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
materials come into contact with parts of the
vehicle which are hot. Take particular care not
to park on dry grassland or harvested grain
fields.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking positionP.
Rstart the engine.
In addition, they may operate vehicle
equipment 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.
