continue models and to change specifications or
design at any time without notice and without
incurring obligation. Descriptions and specifica-
tions contained in this publication provide no
warranty, expressed or implied, and are subject
to revisions and editions without notice.
Environmental Concerns and
Recommendations
Whenever you see instructions in this manual to dis-
card materials, you should first attempt to reclaim
and recycle them. To preserve our environment, fol-
low appropriate environmental rules and regulations
when disposing of materials.
Event Data Recorder
This vehicle is equipped with one or more devices
that record specific vehicle data. The type and
amount of data recorded varies depending on how
the vehicle is equipped (such as the brand of engine,
if an air bag is installed, or if the vehicle features a
collision avoidance system, etc.).
Emissions and Fuel Efficiency
Compliance
This vehicle must be regularly inspected and main-
tained as indicated in the Saf-T-Liner C2 Mainte-
nance Manual, and in the Pre- and Post-Trip Inspec-
tions and Maintenance chapter in this manual, in
order to continue satisfactory performance and en-
sure coverage of the vehicle under the manufactur-
er’s warranty. Many maintenance procedures ensure
that the vehicle and engine continue to comply with
applicable emissions standards. Maintenance proce-
dures, using components engineered to comply with
greenhouse gas emissions and fuel efficiency regula-
tions, may be performed by an authorized Daimler
Trucks North America dealer, an independent outlet,
or the vehicle owner or operator.
The vehicle owner is responsible for determining the
suitability of replacement components to maintain
compliance with federal and local jurisdictional regu-
lations. Components including, but not limited to, low-
rolling resistance tires are specifically designed and
manufactured to exacting standards for regulatory
fuel efficiency and greenhouse gas emissions compli-
ance. It is important that these components are al-
ways replaced with components that meet or exceed
the performance of the originally installed compo-
nents.

Vehicle Certification Plate and
Data Plate
NOTE: Labels shown in this chapter are ex-
amples only. Actual label locations and specifi-
cations may vary from vehicle to vehicle.
The certification plate is installed on the inside roof
liner above the driver’s window, or on the front bulk-
head. The certification plate indicates compliance
with all Federal Motor Vehicle Safety Standards
(FMVSS) at the time of manufacture, gross axle
weight rating (GAWR) front and rear, gross vehicle
weight rating (GVWR), vehicle identification number
(VIN), vehicle type, body identification, and build
date. See Fig. 1.1.
The data plate is installed on the inside roof liner
above the driver’s window, or on the front bulkhead,
and lists manufacturing information. See Fig. 1.2.
Whenever contacting parts, service, or warranty per-
sonnel regarding the vehicle, the following three
numbers will be requested:
• chassis identification number
• body identification number
• VIN
Federal Motor Vehicle Safety
Standard Labels
NOTE: Due to the variety of Federal Motor Ve-
hicle Safety Standard (FMVSS) certification re-
quirements, not all of the labels shown will apply
to your vehicle.
Buses purchased in the U.S. are marked as certified
by means of an FMVSS certification label. See
Fig. 1.3. The tire and rim information are combined
into one label. This label is located in the driver area.
Chassis built without a cargo body that are intended
for service in the U.S. have an incomplete vehicle
certification label attached by the final-stage manu-
facturer. See Fig. 1.4. This label will be attached to
the incomplete vehicle document included with the
vehicle, and certifies that the vehicle conforms to all
applicable FMVSS regulations in effect on the date of
completion.
The tire and rim portion of the FMVSS certification
label certifies suitable tire and rim combinations that
can be installed on the vehicle, for the given gross
axle weight rating. Tires and rims installed on the
vehicle at the time of manufacture may have a higher

load capacity than that certified by the tire and rim
label. If the tires and rims currently on the vehicle
have a lower load capacity than that shown on the
tire and rim label, then the tires and rims determine
the load limitations on each of the axles.
Canadian Motor Vehicle Safety
Standard Labels
In Canada, buses are marked as certified by means
of a statement of compliance label with the Canadian
National Safety Mark, which is located in the driver
area. See Fig. 1.5.
If purchased for service in Canada, chassis built
without a body are marked as certified by a "State-
ment of Compliance" label. See Fig. 1.3. This label
must be attached by the final-stage manufacturer to
certify that the vehicle conforms to all applicable
Canada Motor Vehicle Safety Standard (CMVSS)
regulations in effect on the date of completion..
Tire and Rim Information
The tire and rim label certifies suitable tire and rim
combinations that can be installed on the vehicle for
the given gross axle weight rating. Tires and rims
installed on the vehicle at the time of manufacture
may have a higher load capacity than that certified
by the tire and rim label. If the tires and rims cur-
rently on the vehicle have a lower load capacity than
that shown on the tire and rim label, then the tires
and rims determine the load limitations on each of
the axles.
See Fig. 1.6 for U.S. and Canadian tire and rim
labels.
Vehicle Loading
The gross axle weight rating (GAWR) is the maxi-
mum weight the axle can carry. GAWR is the com-
bined capacity of the axle, brakes, tires, wheel equip-
ment, and suspension.
The gross vehicle weight rating (GVWR) is the maxi-
mum loaded weight of the vehicle. See Fig. 1.3.
NOTICE
Never load the vehicle over the GVWR. Consider-
able damage to the drivetrain may result if the
vehicle is over the GVWR.
IMPORTANT: Passenger and cargo loads
should be distributed proportionately over both
the front and rear axles, and sides of the bus.
NOTE: Actual loads on the front and rear axles
can only be determined by weighing the vehicle
at highway weigh stations or similar facilities.
Overloading the vehicle is considered misuse
and will void the vehicle warranty.
Emissions Labels
EPA Noise Emission Control Label
A vehicle noise emission control label is attached
either to the left side of the dashboard or in the
driver’s area. See Fig. 1.7.
It is the owner’s responsibility to maintain the vehicle
so that it conforms to EPA regulations.
IMPORTANT: Certain incomplete vehicles may
be produced with incomplete noise control hard-
ware. Such vehicles will not have a vehicle
noise emission control information label. For

such vehicles, it is the final-stage manufactur-
er’s responsibility to complete the vehicle in
conformity to U.S. EPA regulations (40 CFR Part
205) and label it for compliance.
Aftertreatment System Indicators
Label
Engines and vehicles manufactured after December
31, 2006 and domiciled in the U.S. or Canada are
required to meet all EPA regulations effective as of
the vehicle build date, and are equipped with an
emission aftertreatment system (ATS). Vehicles do-
miciled outside of the U.S. and Canada may not
have aftertreatment equipment, depending upon local
statutory emissions guidelines. See Table 1.1.
There is a warning label (placement will vary by
bodybuilder) for important warning indicators in the
instrument cluster that pertain to the ATS.
It is a violation of U.S. federal law to alter exhaust
plumbing, ATS, or other components in any way that
would bring the engine/vehicle out of compliance with
certification requirements [Ref: 42 U.S.C. S7522(a)
(3)]. It is the owner’s responsibility to maintain the
vehicle so that it conforms to EPA regulations.
Vehicle Emission Control Information
Label
Model year 2013 and later vehicles meet additional
requirements as specified by federal greenhouse gas
and fuel efficiency regulations (GHG14). These ve-
hicles may be equipped with components, such as
low-rolling resistance tires, that increase fuel effi-
ciency and reduce GHG emissions.
A Vehicle Emission Control Information label is lo-
cated on the fan shroud. See Fig. 1.8. It is the own-
er’s responsibility to maintain the vehicle so that it
conforms to EPA and NHTSA regulations.
