Problem
Possible causes/consequences and
M
MSolutions The starter motor was exposed to excessively high thermal load.
X Start the engine again (Y page 134).
If the engine still does not start: X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not running
smoothly and is misfir-
ing. The engine electronics or a mechanical component of the engine
management system are/is malfunctioning.
X Depress the accelerator pedal only slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. The coolant temperature
display is showing more
than 120 †. A display
message may also
appear on the multifunc-
tion display and a warn-
ing tone may sound. The coolant level is too low. The coolant is too hot and the engine is not
being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 312). Observe the warning notes
as you do so and top up the 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 not being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECT switch

General notes You can shift gears yourself using the steering
wheel gearshift paddles. The transmission must
be in position Dto do this.
Depending on which steering wheel gearshift
paddle is pulled, the automatic transmission
immediately shifts into the next gear up or
down, if permitted.
Mercedes-AMG vehicles: to use manual gear-
shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position D.
If you deactivate manual gearshifting, the gears will be shifted automatically again. 150

indicator on the multifunction display. Always
make sure that the engine speed does not
reach the red area of the rev counter.
X To shift down: pull steering wheel gearshift
paddle :.
The automatic transmission shifts down to
the next gear.
Automatic downshifting 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.
Gearshift recommendation The gearshift recommendation assists you in
adopting a fuel-efficient driving style. The rec-
ommended gear is shown on the multifunction
display.
X When the gearshift recommendation :is
shown on the multifunction display of the
instrument cluster, shift to recommended
gear ;.
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 rev counter. There is
otherwise a risk of engine damage. Before the engine speed reaches the red area,
an upshift indicator will be shown on the multi-
function display.
X When message :appears on the multifunc-
tion display, pull the right-hand steering
wheel gearshift paddle.
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 gearshift paddles.
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 possible
only in the temporary setting. 152

MSolutions The transmission has
problems shifting gear. The transmission is losing oil.
X Have the transmission checked at a qualified specialist workshop
immediately. The acceleration charac-
teristics are deteriorat-

X Switch off the engine.
X Wait at least ten seconds before restarting the engine.
X Shift the transmission to position Dor R.

This section only applies to vehicles with all-
wheel drive (4MATIC). The front and rear axles
are constantly driven.
! Performance tests may only be carried out
on a two-axle roller dynamometer. Otherwise,
the braking system or the transfer case could be damaged. Contact a qualified specialist
workshop for more information on perform-
ance tests.
! Since ESP ®
engages automatically, the igni-
tion must be switched off (the key or Start/
Stop button must be in position 0or 1) if:
R the electric parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC).
The brake system could otherwise be dam-

WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-

The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R The outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds.
R The outer area empties and the
inner area is grey: sporty acceler-
ation. ;
Coasting
(evaluation of all decelera-
tion processes):
R The outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and early release of the accelerator.
The vehicle can coast without use
of the brakes.
R The outer area empties and the
inner area is grey: frequent heavy
braking. =
Constant
(continuous evaluation
over the entire journey):
R The outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and decelera-
tion.
R The outer area empties and the
inner area is grey: fluctuations in
speed. The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under
Bonus fr. start
Bonus fr. start does not
indicate a fixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included on the ECO dis-
play.
An economical driving style involves driving at a
moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation.
R drive the vehicle in drive program E(vehicles
with DYNAMIC SELECT switch)
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 226).

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.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.

and steep downhill gradients. Take particular164
