Wheel And Tire Torque Specifications; Torque Specifications - Fiat 500L 2018 Owner's Manual

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 cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half-
way).
