R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle' sequipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parkin gbrake.
R shifting the automatic transmission out of
park position P
R Start the engine.
There is arisk of an acciden tand injury.
When leaving the vehicle, always tak ethe

General notes 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 arisk of
an accident and injury.
When leaving the vehicle, alway stake the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is amalfunction
in the system, it may not be possible to apply
the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it roll- ing away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake, if the on-board voltage is low
or there is amalfunction in the system. Con-
tact aqualified specialist workshop. Applying/releasing manually

To engage: push handle 0043.
When the electric parking brake is
engaged, the red 0049(USA only) or 0024
(Canada only) indicator lamp lights up in
the instrument cluster.
i The electric parking brake can also be
applied when the SmartKey is in position 0.
X Pull handle 0043.
The red 0049(USA only) or 0024(Canada
only) indicator lamp in the instrument clus- ter goes out.
i The electric parking brake can only then
be released when the ignition is switched
on using the Start/Stop button.
Releasing the electric parking brake
automatically The electric parking brake is released auto-
matically when the following conditions are
simultaneously fulfilled:
R the engine is running
R the transmission is in position Dor R.
R the hood is closed.
R your seat belt is fastened.
R you accelerate.
If the transmission is in position R,the trunk

WARNING
If you operate information system sand com-
munication equipment integrated in the vehi- cle while driving, you will be distracted from
traffic conditions. You could also lose control of the vehicle. There is arisk of an accident.
Only operate the equipment when the traffic
situatio npermits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic condition sand operate the equip-
ment when the vehicle is stationary. G
WARNING
If the instrumen tcluster has failed or mal-
functioned, you may not recogniz efunction

Engine oil temperatured
isplay
The engin eoil temperature gauge is in the
instrumen tcluster on the right-han dside.
Under normal operatin gconditions, the tem-
perature may rise to 140 †.
The transmission fluid temperature and the
coolan ttemperature are displayed in the
AMG menu (Y page 160). Tachometer
The red band in the tachometer indicates the engine's overrevvin grange.
! Do not drive in the overrevvin
grange, as
this could damage the engine.
The fuel supply is interrupted to protect the
engin ewhen the red band is reached. Outside temperatured

Otherwise, the vehicle's electronic sys-
tem may be damaged.
R the transmission is locked in position P

cle is secured against rolling away. You
can then no longer move the vehicle.
The batter yand the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precaution sand take pro-
tective measures when handling batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks. Battery acid is caustic
.Avoid con-
tact with skin ,eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Rinse any acid spills immediately
with clear water. Contac taphysi-
cian if necessary. Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benzr ecom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide increased impact protection to preven
tvehi-
cle occupants from sufferin gacid burns
should the batter ybedamaged in the event of
an accident.
In order for the batter ytoachieve the maxi-
mum possible servic elife, it must alway sbe
sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the batter ydiscon-
nected at aqualified specialist workshop. You
can also charge the batter ywithacharger
recommended by Mercedes-Benz. Contac ta
qualified specialist worksho pfor further infor-
mation.
Have the batter ycondition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for alengthy period. Consult aqualified spe-
cialist worksho pifyou wish to leave your
vehicle parked for along period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conservin gbattery
power.
i If the batter
ypower supply has been inter-
rupted, e.g. if the batter ywas fully dis-
charged, you will need to reset the "exterior
