WARNING
Never Exceed Axle Weight Rating
Limits:
Exceeding the Safety Certification
Label axle weight rating limits is
dangerous and could result in death or
serious injury as a result of substandard
vehicle handling, performance, motor,
EV transaxle and/or structural damage,
serious damage to the vehicle, or loss
of control.
Always keep the vehicle within the axle
weight rating limits.
GCW
GCW (Gross Combination Weight) is
the weight of the loaded vehicle
(GVW).
GCWR (Gross Combination Weight
Rating) is the maximum allowable
weight of the vehicle - including all
cargo and passengers - that the vehicle
can handle without risking damage.
The GCW must never exceed the
GCWR.
WARNING
Never Exceed GVWR or GAWR
Specifications:
Exceeding the GVWR or the GAWR
specified on the certification label is
dangerous. Exceeding any vehicle
rating limitation could result in a
serious accident, injury, or damage to
the vehicle.
8-30
Do not use replacement tires with
lower load carrying capacities than the
originals because they may lower the
vehicle's GVWR and GAWR
limitations. Replacement tires with a
higher limit than the originals do not
increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR
specified on the certification label.
