WARNING
Your SUZUKI is equipped with tires
which are all the same type and size.
This is important to ensure proper
steering and handling of the vehicle.
Never mix tires of different size or
type on the four wheels of your vehi-
cle. Mixing tires could cause you to
lose control while driving which may
lead to an accident. The size and type
of tires used should be only those
approved by SUZUKI Motor Corpora-
tion as standard or optional equip-
ment for your vehicle.
