Impacts from road surfaces
■
This vehicle is equipped with low profile tires, which may cause greater damage
than usual to tires, wheels, body and suspension due to impacts from road surfaces.
Therefore, pay attention to the following:
Be sure to use proper tire inflation pressure.
●
If tires are under-inflated, tires and wheels may be damaged more severely.
Avoid potholes, uneven pavement, curbs and other road hazards.
●
Failure to do so may lead to severe tire, wheel, body and suspension damage.
Even if there is no obvious damage, if the vehicle receives an impact from the road
surface, have it inspected at your Lexus dealer.
If tire inflation pressure of each tire becomes low while driving
■
Do not continue driving, or your tires and/or wheels may be ruined.
Tire precautions during cold weather
■
This vehicle is fitted with high-grip tires to enhance grip. These tires may be dam-
aged if their temperature falls below -31F (-35C). In extremely cold conditions,
use snow tires on the vehicle and keep the high-grip tires in a warm place.
Even if there is no obvious damage, if the temperature of the high-grip tires falls
below -31F (-35C), have them inspected at your Lexus dealer.
