Driving on Uneven Road
▼Driving on Uneven Road
Your vehicle's suspension and underbody
can be damaged if driven on rough/uneven
roads or over speed bumps at excessive
speeds. Use care and reduce speed when
traveling on rough/uneven roads or over
speed bumps.

Use care not to damage the vehicle's
underbody, bumpers or muffler(s) when
driving under the following conditions:
Ascending or descending a slope with a
sharp transition angle
Ascending or descending a driveway or
trailer ramp with a
sharp transition angle

This vehicle is equi pped with low profile
tires allowing class-leading performance
and handling. As a result, the sidewall of
the tires are very th in and the tires and
wheels can be damaged if driven through
potholes or on rough/uneven roads at
excessive speeds. Use care and reduce
speed when traveling on rough/uneven
roads or through potholes.
