WARNING Accident statistics show that children 
Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat.
For this reason, Mercedes-Benz strongly advises that you always secure children in the rear seats. Regardless of the seat position, children under 12 years must be secured correctly in a suitable infant or child restraint system or booster seat suitable for the size and weight of the child.
Secure the infant restraint system or child restraint system using:
the seat belt of the vehicle
the seat belt and a Top Tether belt
the LATCH-type (ISOFIX) child seat mount and a Top Tether belt
The child restraint system must be installed and secured correctly, observing the manufacturer's installation instructions.
Occupants, in particular children, must sit as upright as possible, fasten the seat belt correctly and use a suitable infant restraint system, child restraint system or booster seat suitable for the size and weight of the child.
Children can be seriously or even fatally injured by an air bag deploying. Observe the following important information if it is necessary to carry a child on the frontpassenger seat:
Canada only: children under 12 years of age may only sit in the front-passenger seat if they are seated in a child restraint system which is compatible with BabySmart™ and approved by Mercedes-Benz. When the child restraint system is installed correctly, the front-passenger front air bag is disabled in conjunction with the BabySmart™ system installed in the vehicle. If the frontpassenger front air bag is deployed in the event of a collision, it could hit the child.
This could lead to serious or fatal injuries.
A child in a rearward-facing child restraint system on the front-passenger seat could be seriously injured or even killed if the front-passenger front air bag inflates in a collision despite the air bag technology installed in your vehicle, which could occur under some circumstances. The only way to completely rule out this risk is by making sure you never place a child in a rearwardfacing child restraint system on the frontpassenger seat. For this reason, we strongly advise that you always carry children in a rearward-facing child restraint system on a rear seat.
If it is necessary to install a BabySmart™- compatible rear-facing child restraint system on the front-passenger seat, make sure the illuminated. This indicates that the frontpassenger indicator lamp is illuminated. This indicates that the frontpassenger front air bag is deactivated. If the light up or goes out when the child restraint system is installed, check the indicator lamp does not light up or goes out when the child restraint system is installed, check the anchorages of the restraint system. Periodically check the driving to make sure the indicator lamp while driving to make sure the indicator lamp is illuminated. If the indicator lamp is illuminated. If the remains out, you may only carry a child on indicator lamp goes out or remains out, you may only carry a child on the front-passenger seat once the system has been repaired.
A child in a rearward-facing child restraint system on the front-passenger seat can be seriously injured or even killed if the frontpassenger front air bag is deployed.
When securing a child in a front-facing child restraint system on the front-passenger seat, you must:
- move the front-passenger seat as far back as possible
- use a child restraint system that is suitable for the age, size and weight of the child
- observe the manufacturer's installation instructions in order to install and secure the child restraint system correctly.

WARNING The BabySmart™ air bag disabling system 
The BabySmart™ air bag disabling system ONLY works with specially adapted child restraint systems. It does not work with child restraint systems that are not compatible with BabySmart™.
Never place anything between the seat cushion and the child restraint system (e.g. a cushion), as this reduces the effectiveness of the BabySmart™ air bag deactivation system.
The underside of the child restraint system must lie against the seat cushion of the frontpassenger seat. In the event of an accident, an incorrectly installed child restraint system could injure the child instead of offering protection.
Observe the manufacturer's instructions when installing special child restraint systems.
