Installing a child restraint system:
XMake sure you observe the child restraintsystem manufacturer's installation instruc-tions.
XPull the seat belt smoothly out of the seatbelt guide.
XEngage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertiareel retract it again.While the seat belt is retracting, you shouldhear a ratcheting sound. The special seatbelt retractor is enabled.
XPush the child restraint system down so thatthe seat belt is tight and does not loosen.
Removing the child restraint system and deac-tivating the special seat belt retractor:
XMake sure you observe the child restraintsystem manufacturer's installation instruc-tions.
XPress the release button of the seat beltbuckle and route the seat belt tongue backtowards the seat belt guide.The special seat belt retractor is deactiva-ted.
child restraint system
The use of seat belts and child restraint sys-tems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
You can obtain further information about thecorrect child restraint system from any author-ized Mercedes-Benz Center.
GWARNING
If the child restraint system is installed
incorrectly on a suitable seat, it cannot pro-
tect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Make sure that you observe the child
restraint system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g. cush-
ions, under or behind the child restraint sys-
tem. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine cov-
ers.
GWARNING
If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking or a sudden change in direction. The
child restraint system could be thrown
about, striking vehicle occupants. There is
an increased risk of injury, possibly even
fatal.
Always install child restraint systems prop-
erly, even if they are not being used. Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
Further information on stowing objects, lug-gage and loads securely can be found under“Stowing options/stowage compartments”(Ypage 249).
GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjec-
ted to a load in an accident can no longer
protect as intended. The child cannot then
be restrained in the event of an accident,
heavy braking or sudden changes of direc-
tion. There is an increased risk of injury,
possibly even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint sys-
tem checked at a qualified specialist work-
shop, before you install a child restraint sys-
tem again.
The securing system of child restraint systemsis the seat belt system.

Safety

the vehicle on the desired course within physi-
cal limits. ESP®assists the driver when pulling
away on wet or slippery roads. ESP®can alsostabilize the vehicle during braking.
ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-tion (Ypage 60).
ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if theyspin. This enables you to pull away and accel-erate on slippery surfaces, for example if theroad surface is slippery on one side. In addi-tion, more drive torque is transferred to thewheel or wheels with traction.
ETS remains active when you deactivate ESP®.
iMercedes-AMG vehicles:your vehiclemay be equipped with 20-inch tires on therear axle. After changing to 19 inch wheels,ETS may intervene noticeably earlier duringthe first few kilometers. After approximately10 km ETS will function as usual again.Information on the dimensions and types ofwheels and tires for your vehicle can befound in the "Wheel/tire combinations" sec-tion (Ypage 318).
Important safety notes
GWARNING
If ESP®is malfunctioning it will not provide
any vehicle stabilization. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP®checked at a qualified specialist
workshop.
When towing the vehicle with the rear axle
raised, observe the notes on ESP®
(Ypage 290).

ProblemPossible causes/consequences andPPSolutions
The engine is not run-ning smoothly and ismisfiring.
There is a malfunction in the engine electronics or in a mechanicalcomponent of the engine management system.
XOnly depress the accelerator pedal slightly.Otherwise, non-combusted fuel may get into the catalytic con-verter and damage it.
XHave the cause rectified immediately at a qualified specialistworkshop.
The coolant tempera-ture display shows avalue above 248 ‡(120 †). The coolantwarning lamp may alsobe on and a warningtone may sound.
The coolant level is too low. The coolant is too hot and the engine isno longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 267). Observe the warning notesas 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 suf-ficiently.
XAt coolant temperatures below 248 ‡ (120 †), drive to the near-est qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving inmountainous terrain and stop-and-go traffic.
Notes on towing vehicles
The vehicle is not suitable for attaching towbar systems, such as those used for flat tow-ing or dinghy towing.
Attaching or using tow bar systems may resultin damage to the vehicle.
When towing a vehicle with tow bar systems,safe driving characteristics cannot be guaran-teed for the towing vehicle or the towed vehi-cle.
The vehicle/vehicle combination may swerve.
Observe the permissible towing methods(Ypage 289) and the notes on towing withboth axles on the ground (Ypage 289).
