Caution!
Do not remove head restraints except when mounting 
seat covers. For removal see page 43. Whenever head 
restraints have been removed be sure to reinstall them 
before driving.
Wa r n i n g !
Do not adjust the driver’s seat while driving. 
Adjusting the seat while driving could cause the 
driver to lose control of the vehicle.Never ride in a moving vehicle with the backrest 
reclined. Sitting in an excessively reclined position 
can be dangerous. You could slide under the seat 
belt in a collision. If you slide under it, the belt 
would apply force at the abdomen or neck. That 
could cause serious or even fatal injuries. The 
backrest and seat belt provide the best restraint 
when the wearer is in an upright position and the 
belt is properly positioned on the body.Never place hands under seat or near any moving 
parts while a seat is being adjusted.
Wa r n i n g !
When leaving the vehicle always remove the key 
from the steering lock, and lock your vehicle.Do not leave children unattended in the vehicle or 
with access to an unlocked vehicle. Unsupervised 
use of vehicle equipment may cause serious 
personal injury.

Important!
Prior to operating the vehicle, the driver should adjust 
the seat height for proper vision as well as fore / aft 
placement and backrest angle to insure adequate 
control, reach, operation, and comfort. The head 
restraint should also be adjusted for proper height. See 
also airbag section on page 56 for proper seat 
positioning.
In addition, also adjust the steering wheel to ensure 
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be 
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be 
seated in a properly secured restraint system that 
complies with U.S. Federal Motor Vehicle Safety 
Standard 213 and Canadian Motor Vehicle Safety 
Standard 213.
All seat, head restraint, steering wheel, and rear view 
mirror adjustments as well as fastening of seat belts 
should be done before the vehicle is put into motion.
Wa r n i n g !
Children 12 years old and under must never ride in 
the front seat, except in a Mercedes-Benz 
authorized BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM system 
installed in the vehicle to deactivate the passenger 
side front airbag when it is properly installed. 
Otherwise they will be struck by the airbag when it 
inflates in a crash. If this happens, serious or fatal 
injury can result.
According to accident statistics, children are safer 
when properly restrained in the rear seating 
positions than in the front seating positions. 
Infants and small children must ride in the back 
seats and be seated in an appropriate infant or 
child restraint system, which is properly secured 
with the vehicle’s seat belt, fully in accordance 
with the child seat manufacturer’s instructions.A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints are 
not properly secured in the vehicle and the child is 
not properly secured in the child restraint.

Seat belts and integrated restraint system
Your vehicle is equipped with seat belts for all seats, 
emergency tensioning retractors for front and second 
row outboard seat belts, dual front airbags and door 
mounted side impact airbags. Their protective functions 
are designed to complement one another.
Seat belts
Important!
Laws in most states and all Canadian provinces require 
seat belt use.
All states and provinces require use of child restraints 
that comply with U.S. Federal Motor Vehicle Safety 
Standard 213 and Canadian Motor Vehicle Safety 
Standard 213.
All child restraint systems are designed to be secured in 
vehicle seats by lap belts or the lap belt portion of a lap-
shoulder belt.
For your safety and that of your passengers we strongly 
recommend their use.

TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed 
for use with the Mercedes-Benz system and available at 
any authorized Mercedes-Benz Center are required for 
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the 
passenger front airbag will not deploy. The 7 
indicator lamp located in the instrument cluster will be 
illuminated, except with key removed or in steering lock 
position 0. The system does not deactivate the door 
mounted side impact airbag.
Self-test BabySmart
TM 
without special child seat installed
After turning key in steering lock to position 1 or 2, the 
7 indicator lamp located in the instrument cluster 
comes on for approximately 6 seconds, extinguishes, 
then blinks once.
If the indicator lamp should not come on or is 
continuously lit, the system is not functioning. You must 
see an authorized Mercedes-Benz Center before seating 
any child on the front passenger seat.

Wa r n i n g !
The BabySmart
TM Airbag Deactivation System will 
ONLY work with a special child seat designed to 
operate with it. It will not work with child seats 
which are not BabySmart
TM compatible.
Never place anything between seat cushion and 
child seat (e.g. pillow), since it reduces the 
effectiveness of the deactivation system.Follow the manufacturer’s instructions for 
installation of special child seats.
The passenger side front airbag will not deploy 
only if the 7 indicator lamp remains 
illuminated.Please be sure to check the indicator every time 
you use the special system child seat.Should the light go out while the restraint is 
installed, please check installation. If the light 
remains out, do not use the BabySmart
TM restraint 
to transport children on the front passenger seat 
until the system has been repaired.
