●Stop the vehicle in a safe place on a hard, flat surface.
●Set the parking brake.
●Shift the shift lever to P.
●Stop the hybrid system.
●Turn on the emergency flashers. ( P. 546)
●Check the degree of the tire damage.
A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw passing
through the tire tread.
• Do not remove the nail or
screw from the tire. Removing
the object may widen the
opening and disenable emer-
gency repair with the kit.
• To avoid sealant leakage, move
the vehicle until the area of the
puncture, if known, is posi-
tioned at the top of the tire.
