Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Running-in notes

Risk of accident
New brake pads/linings only have optimal
braking performance after several hundred
kilometres. Until then, compensate for this by
applying greater force to the brake pedal. This
also applies when brake pads/linings or
brake discs have been changed. The first 1,500 km
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R Therefore, drive at varying speeds and
engine speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R Change gear in good time, at the latest
when the rev counter needle is 2
/ 3 of the
way to the red area in the rev counter dis-
play.
R Do not manually shift to a lower gear to
brake the vehicle.
R if possible, do not depress the accelerator
pedal past the point of resistance (kick-
down).
R only select shift ranges 3,2or 1when driv-
ing slowly, e.g. in mountainous terrain.
After 1,500 km, you may gradually bring the
vehicle up to full road and engine speeds. Additional running-in notes for AMG vehicles:
R
do not drive at speeds above 140 km/h for
the first 1,500 km.
R only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
i You should also observe these notes on
running in if the engine or parts of the drive
train on your vehicle have been replaced. AMG vehicles with rear axle locking
differential
Your vehicle is fitted with a self-locking dif-
ferential on the rear axle. Change the oil after
a running-in period of 3,000 km to improve
protection of the rear axle differential. This oil
change extends the service life of the differ-
ential. Have the oil change carried out at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. Driving

Risk of accident
Do not place any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that it is correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Loose objects or the floormats could other-
wise get caught between the pedals if you
accelerate or brake suddenly. You will then
not be able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and 128

the vehicle could skid. Thi
scould cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protect the
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions

Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. a Mercedes-Benz Service Centre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit 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.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 268). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop e.g. to a Mercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Automatic transmission

Introduction i
OnAMG vehicles andvehicles with
steering wheel gearshift paddles, you
can restrict or derestrict the shift range
using the steering wheel gearshift paddles.
When the automatic transmission is in posi-
tion D, it is possible to restrict or derestrict
the shift range (Y page 140).
The shift range selected is shown in the mul-
tifunction display .The automatic transmis-
sion shifts only as far as the selected gear. Driving situations

engine on downhill gradients and
for driving:
R
on steep mountain roads
R in mountainous terrain
R in arduous conditions 4
To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting the shift range
X
Pull the left-hand steering wheel gearshift
paddle.
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, even if the shift range is restricted.
Derestricting the shift range X
Pull the right-hand steering wheel gearshift
paddle.
The shift range is derestricted.
Clearing the shift range restriction X
Pull the right-hand steering wheel gearshift
paddle until the number for the gear disap-
pears from the multifunction display.

matically even when the engine limiting
speed for the current geari s reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. You must make sure that
the engine speed does not reach the red area of the rev counter. Otherwise, there is
a risk of engine damage.
X Shift up a gear if the colour in the multi-
function display in the speedometer
changes to red and UP appears in the rev
counter.
Downshifting X
