Pretrip inspection and maintenance
1. While driving slowly, make sure that the steering
wheel does not shake and the vehicle does not
pull to one side. The wheel should turn easily,
without excessive operating resistance, and
return smoothly to the neutral position.
2. If any problem is found, call an authorized Ster-
ling service facility for inspection.
The service brakes are critical to vehicle safety. If
an inspection reveals any problem, contact an
authorized Sterling service facility to solve the prob-
lem.
