child restraint system manufacturer's instal-lation instructions.
Ralways observe the instructions and safetynotes on the "Occupant classification sys-tem (OCS)". (Ypage 47)
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
Rrelease the parking brake.
Rshift the automatic transmission out of
the parking positionP.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
GWARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly. Particular attention must be paidto children.
Observe the safety notes on the seat belt(Ypage 41) and the notes on correct use ofseat belts (Ypage 42).
A booster seat may be necessary to achieveproper seat belt positioning for children over40 lbs (18 kg) until they reach a height wherea three-point seat belt can be properly fas-tened without a booster seat.
Special seatbelt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
All seat belts in the vehicle, except the driver'sseat belt, are equipped with a special seat beltretractor. When activated, the special seat beltretractor ensures that the seat belt cannotslacken once the child seat is secured.

you install the child restraint system on a rearseat.
If it is absolutely necessary to install a childrestraint system on the front-passenger seat,always observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Ypage 47).
You can thus avoid the risks that could ariseas a result of:
Ran incorrectly categorized person in thefront-passenger seat
Rdeactivating the front passenger front airbag unintentionally
Rthe unsuitable positioning of the childrestraint system, e.g. too close to the dash-board
Rearward-facing child restraint system
If circumstances require you to secure a childin a rearward-facing child restraint system onthe front-passenger seat, always make surethat the front passenger front air bag is deacti-vated. Only if the PASSENGER AIR BAG OFFindicator lamp is lit continuously (Ypage 40),is the front passenger front air bag deactiva-ted.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.
Forward-facing child restraint system
If it is absolutely necessary to install aforward-facing child restraint system on thefront-passenger seat, always move the front-passenger seat as far back as possible. Fullyretract the seat cushion length. The entirebase of the child restraint system must alwaysrest on the seat cushion of the front-passenger seat. The backrest of the childrestraint system must lie as flat as possibleagainst the backrest of the front-passengerseat. The child restraint system must nottouch the roof or be subjected to a load by thehead restraint. Adjust the angle of the seatbackrest and the head restraint positionaccordingly. Always make sure that the shoul-der belt strap is correctly routed from the vehi-cle belt outlet to the shoulder belt guide onthe child restraint system. The shoulder beltstrap must be routed forward and down fromthe vehicle belt outlet. If necessary, adjust the
vehicle belt outlet and the front-passengerseat accordingly.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.

Situation-dependent braking assis-
tance
General information
iObserve the "Important safety notes" sec-tion (Ypage 60).
With the help of the radar sensor system,Active Brake Assist can detect obstacles thatare in the path of your vehicle for an extendedperiod of time.
If Active Brake Assist detects a risk of collisionwith the vehicle in front, it calculates the brakepressure necessary to avoid a collision. If youapply the brakes forcefully, situation-depend-ent braking assistance adapts to the situationand automatically increases the brake pres-sure to a degree appropriate to the traffic sit-uation.
Situation-dependent braking assistance pro-vides braking assistance in hazardous situa-tions at speeds above 4 mph (7 km/h). It usesradar sensor technology to assess the trafficsituation.
Situation-dependent braking assistance iscapable of reacting to moving objects thathave already been detected as such at leastonce over the period of observation, up tovehicle speeds of around 155 mph(250 km/h).
Situation-dependent braking assistance canalso detect stationary objects, up to vehiclespeeds of around 44 mph (70 km/h).
XKeep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.
The brakes will work normally again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehi-cle
Situation-dependent braking assistance is thendeactivated.
Important safety notes
iObserve the "Important safety notes" sec-tion for driving safety systems (Ypage 60).
GWARNING
Active Brake Assist does not react:
Rto persons, bicycles, motorcycles or ani-
mals
Rto approaching vehicles
Rto cross traffic
Ron bends
As a result, Active Brake Assist cannot inter-
vene in all critical situations. There is a risk
of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate
the intervention in a non-critical driving sit-
uation.
Due to the nature of the system, complex butnon-critical driving conditions may also causeActive Brake Assist to intervene.
Even if Active Brake Assist is not available dueto a malfunction in the radar sensor system,the brake system is still available with fullbrake boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
ESP®monitors driving stability and traction,i.e. power transmission between the tires andthe road surface.
If ESP®detects that the vehicle is deviatingfrom the direction desired by the driver, one ormore wheels are braked to stabilize the vehi-

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped withSmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-ton.
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example,when starting the engine.
When you insert the Start/Stop button intothe ignition lock, the system needs approx-imately two seconds recognition time. You canthen use the Start/Stop button.
Pressing the Start/Stop button several timesin succession corresponds to the differentSmartKey positions in the ignition lock. This isonly the case if you are not depressing thebrake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted inthe ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 70)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metalfoil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKeyremote control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will no longer be able to start the enginewith the Start/Stop button until the vehicleis unlocked again.
If you lock the vehicle centrally using the but-ton on the front door (Ypage 75), you cancontinue to start the engine with the Start/Stop button.
