6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire valve caps. Without the
valve caps, dirt or moisture could get into the
valve core and cause air leakage. If the caps have
been lost, have new ones put on as soon as
possible.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire needs frequent refilling, have it checked by your
Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation)Ð
Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire separation
 A greater possibility of tire damage from road
hazards
High tire pressure (overinflation)Ð
 Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire damage from road
hazards
