ProblemPossible causes/consequences andMSolutions
The coolant tempera-
ture gauge shows a
value above 248 ‡
(120 †). The coolant
warning lamp may also
be on and a warning
tone may sound.The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 539). Observe the warning
notes as you do so and add coolant if necessary.
If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
XAt coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-and-go traffic.
Automatic transmission
Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.

Overview of transmission positions
!If the engine speed is too high or if the
vehicle is rolling, do not shift the transmis-
sion directly from Dto R, from Rto Dor
directly to P.
Do not open the driver's door while the
vehicle is in motion. At low speeds in trans-
mission position Dor R, park position Pis

BPark position
Only shift the transmission into
positionPwhen the vehicle is sta-
tionary (
Ypage 159). The parking
lock should not be used as a brake
when parking. Always apply the
electronic parking brake in addi-
tion to the parking lock in order to
secure the vehicle.
If the SmartKey is removed from
the ignition lock, the transmission
is locked.
The automatic transmission shifts
into Pautomatically:
Rwhen the SmartKey is removed

R or Dand one of the doors is
opened
If the vehicle electronics are mal-
functioning, the transmission may
be locked in position P. Have the
vehicle electronics checked imme-
diately at a qualified specialist
workshop.
CReverse gear
Only shift the transmission into
position Rwhen the vehicle is sta-
tionary.
ANeutral
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 brake pedal 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 only to posi-
tion Nif the vehicle is in danger of
skidding, e.g. on icy roads.
!Rolling in neutral Ncan damage
the drive train.
7Drive
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:
Rthe selected drive program (Ypage 163)
Rthe position of the accelerator pedal
(
Ypage 162)
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

General notes
In this drive program, you can briefly change
gear yourself by using the steering wheel pad- dle shifters. The transmission must be in posi-
tion D.
You can activate manual drive program Min
the Eand Sautomatic drive programs.
iAs well as temporary drive program M,
you can also activate permanent drive pro-

Activating
XShift the transmission to position D.
XPull the left or right steering wheel paddle
shifter (
Ypage 164).
Manual drive program Mis temporarily acti-
vated. The selected gear and Mappear in
the multifunction display.
Shifting gears
If you pull on the left or right steering wheel
paddle shifter, the automatic transmission
switches to manual drive program Mfor a
limited amount of time. Depending on which
paddle shifter is pulled, the automatic trans- mission immediately shifts into the next gear
down or up, if permitted.
XTo shift up:
pull the right-hand steering
wheel paddle shifter (
Ypage 164).
The automatic transmission shifts up to the
next gear.
iIf the maximum engine speed on the cur-
rently engaged gear is reached and you
continue to accelerate, the automatic
transmission automatically shifts up in
order to prevent engine damage.
XTo shift down: pull on the left-hand steer-
ing wheel paddle shifter (
Ypage 164).
The automatic transmission shifts down to
the next gear.
iIf the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
iAutomatic down shifting occurs when
coasting.
Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display.
XShift to recommended gear ;according
to gearshift recommendation :when
shown in the multifunction display of the
instrument cluster.
Disarming
If you have activated manual drive program
M , it will remain 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 terrain.

Mercedes-AMG vehicles
!In manual drive programM, 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.
:Gear indicator
;Upshift indicator
Before the engine speed reaches the red area,
an upshift indicator will be shown in the mul-
tifunction display.
XWhen the UPmessage is shown in the mul-
tifunction display, pull on the right-hand
steering wheel paddle shifter.
Kickdown
You can also use kickdown for maximum
acceleration in manual drive program M.
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
Mercedes-AMG vehicles: it is not possible
to use kickdown in manual drive program M.

Refueling
Important safety notes
GWARNING
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.
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.
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 with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
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.
168Refueling
Driving and parking

Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion 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 quali-
fied 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.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
For further information on fuel and fuel quality
(
Ypage 603).
