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 guide the seat belt tongue backtowards the belt sash 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
If you install a rearward-facing child restraintsystem on the center rear seat, the rear seatarmrest must be folded back as far as it willgo.
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.
You will find further information on stowingobjects, luggage or loads under "Loadingguidelines" (Ypage 250).
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 systems of child restraint sys-tems are:
Rthe seat belt system
Rthe LATCH-type (ISOFIX) securing rings
Rthe Top Tether anchorages
If it is absolutely necessary to carry a child onthe front passenger seat, be sure to observethe information on the "Occupant Classifica-tion System (OCS)" (Ypage 47). There you willalso find information on disabling the frontpassenger front air bag.

cle. The engine output is also modified to keepthe 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/4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-tion (Ypage 60).
ETS traction control is part of ESP®. On vehi-
cles with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pullaway and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is transfer-red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP®.
Off-road 4ETS (Electronic Traction Sys-
tem)
A 4ETS system specifically suited to off-roadterrain is activated automatically once the off-road program is activated (Ypage 170).
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an acci-
dent.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
Vehicles without 4MATIC:when towing yourvehicle with the front axle raised, it is impor-
tant that you observe the notes on ESP®
(Ypage 299).

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 gauge shows avalue above 248 ‡(120 †). The warninglamp may also be onand a warning tone maysound.
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 276). Observe the warning notesas you do so and add coolant if necessary.
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/trailer combination may swerve.
Observe the permissible towing methods(Ypage 300) and the notes on towing withboth axles on the ground (Ypage 300).
DYNAMIC SELECT button (all vehi-
cles except Mercedes-AMG vehicles)
