Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will be
some loss of overall braking effectiveness. You
may notice increased pedal travel during

application, greater pedal force required to slow
or stop, and potential activation of the "Brake
System Warning Light".
In the event power assist is lost for any reason
(i.e., repeated brake applications with the
engine off), the brakes will still function.
However, the effort required to brake the
vehicle will be much greater than that required
with the power system operating.

WHEEL AND TIRE TORQUE SPECIFICATIONS

Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a high quality six
sided (hex) deep wall socket.
