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.)
Precaution for Installing Mobile Communication Equipment
When installing mobile communication equipment such as CB (Citizens-Band) -radio or cellular-tele-
phone, be sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic control system.
• Keep the antenna as far away as possible from the vehicle's electronic control unit.
• Keep the antenna feeder more than 20 cm (7.9 in) away from electronic control unit and its wire har-
nesses.
• Do not run the antenna feeder parallel with other wire harnesses.
• Confirm that the antenna and feeder are correctly adjusted.
