passenger should always wear seat belts. The steer-
ing wheel air bag will activate during a collision even
if the seat belts are not fastened, but the system is
designed to provide protection to the occupant only
when the seat belts are fastened.
WARNING
Keep all heavy objects in the cab secured. Do not
place objects on the steering wheel or between
you and the steering wheel. Any such objects
may cause harm during an accident. Keep your
hands on the sides and lower portion of the
steering wheel. Failure to follow these instruc-
tions may result in death or personal injury.
For maximum protection in a collision, always be in a
normal seated position with your back against the
seat back and your head upright. Fasten your seat
belt and ensure that it is properly positioned on your
body as described under the "Seat Belt Operation"
heading. Since the air bag inflates with considerable
speed and force, a proper seat position will help
keep you a safe distance from the inflating air bag.
Inspection and Service
WARNING
Do not attempt to service or modify the air bag
system. Unintentional or improper air bag deploy-
ment could cause severe bodily injury or death.
Contact an authorized Freightliner service facility
for all service and maintenance.
The air bag system contains components that
use combustible chemicals. Do not cut, drill,
braze, solder, weld, strike, or probe the air bag
components. Keep all liquids and chemicals
away from air bag components.
The surface of the deployed air bag may contain
small amounts of sodium hydroxide (which is a
by-product of the gas generant combustion) and
metallic sodium. Sodium hydroxide may be irri-
tating to the skin and eyes. Immediately wash
your hands and exposed skin areas with a mild
soap and water. Flush your eyes immediately if
exposed to sodium hydroxide.
The operational readiness of the air bag system is
indicated by the supplemental restraint system (SRS)
indicator on the dash. The SRS indicator illuminates
for several seconds when the ignition is turned on,
and then it goes off. The indicator will remain on if
there is a problem with the air bag system. The ve-
hicle should be serviced if the SRS indicator does
not illuminate when the ignition is turned on, or if the
SRS indicator remains on.
The air bag module may contain perchlorate mate-
rial; for information, see
www.dtsc.ca.gov/
hazardouswaste/perchlorate
. Special handling may
apply; follow appropriate rules and regulations when
disposing of materials.
For all service and maintenance, contact an autho-
rized Freightliner service facility.
RollTek Rollover Protection
System
Identification
Only seats with the RollTek module under the seat
and the molded side-roll air bag cover on the upper
side of the seat back are equipped with the RollTek
rollover protection system; see
Fig. 7.13
. RollTek
may be installed in one of the following configura-
tions:
•
driver seat only or driver and passenger seats
•
driver seat only, with an optional steering
wheel frontal air bag
•
driver and passenger seats, with an optional
steering wheel frontal air bag
Operation
The RollTek system, when used with seat belts, pro-
vides additional protection to the driver and passen-
ger (if equipped with a passenger-side system) in
rollover accidents. The RollTek system provides a
significant increase in seat stability during a rollover.
Vehicles equipped with RollTek rollover protection
have a sensor mounted in the seat base that acti-
vates the side-roll air bag and seat pull-down device
during a rollover.
When the RollTek module senses a rollover, the
module triggers gas cylinders mounted in the base of
the seat. The gas cylinders activate the power
cinches that then tighten the lap and shoulder belts
against the occupant of the seat and lower the seat
suspension, moving the occupant down and away
from the steering wheel and ceiling. The side-roll air
