driver seat adjustment MERCEDES-BENZ R500 2006 W251 Owner's Manual

42 Getting startedAdjustingSeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
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 seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 50).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the power seats can be operated when the
respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and / or seri-
ous personal injury.
Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(page 82).
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.

ble.
Warning!
G
Only adjust the steering wheel with the vehi-
cle at a standstill and make sure the steer-
ing wheel is securely locked in place before
driving off.
Driving without the steering wheel adjust-
ment locked may cause an unexpected
steering wheel movement which could
cause the driver to lose control of the vehi-
cle. Make sure the steering wheel is secure-
ly locked by trying to move it up and down,
and in and out before driving off.

Make sure your legs can move freely
and that all displays (including malfunc-
tion and indicator lamps) on the instru-
ment cluster are clearly visible.
Mirrors
Adjust the interior and exterior rear view
mirrors before driving so that you have a
good view of the road and traffic condi-
tions.
iThe memory function (
page 144) lets
you store the settings for the steering
wheel column together with the set-
tings for seat positions and the exterior
rear view mirrors.
Warning!
G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their
liquid state and by applying plenty of
water.

72 Safety and SecurityOccupant safetyWarning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body
(page 50).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:


Sit properly belted in a nearly upright
position with your back against the seat
backrest.


Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Light Truck Center.


Do not lean your head or chest close to
the steering wheel or dashboard.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand / arm injury
when driver’s front air bag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the air bag be triggered. Always sit near-
ly upright, properly use the seat belts
and use an appropriately sized infant or
toddler restraint or booster seat recom-
mended for the size and weight of the
child.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
