Precaution for Wheel (with Tire) Removal

Each wheel of this vehicle is installed using wheel bolts. When removing any of these wheels, never
remove all wheel bolts at the same time. Leave at least 1 bolt for each wheel as it is to prevent wheel
from dropping. When removing this remaining 1 bolt, hold wheel and tire so as not to allow them to
come off.

Precautions for Catalytic Converter

For vehicles equipped with a catalytic converter, use only unleaded gasoline and be careful not to let a
large amount of unburned gasoline enter the converter or it can be damaged.
• Conduct a spark jump test only when necessary, make it as short as possible, and do not open the
throttle.
• Conduct engine compression checks within the shortest possible time.
• Avoid situations which can result in engine misfire (e.g. starting the engine when the fuel tank is
nearly empty.)

• Always be careful not to handle electrical parts (com-
puter, relay, etc.) in a rough manner or drop them.
• The loose (1) in the wire harnesses twist of the CAN lines
except around the connector (3) should be within 100 mm
(3.9 in.) Refer to the wiring diagram for the CAN line discrim-
ination. Excessive loosed lines may be influenced by the
electric noise.

• Do not connect terminals of the CAN line using a bypass
wire (1). Otherwise, the CAN line may be influenced by the
electric noise.
