*1: Check ignition coil and spark plug.
*2: Indicate the symptom occurring only in cold temperatures.
*3: Ensure the secure installation.
*4: Check fuel injector and fuel filter.
*5: Inspect air leak in air intake system.
Installing forward facing child restraint
WARNING
Before installing a child restraint
system, be sure to confirm that the
seatback is securely locked into
place. Otherwise, in an accident,
serious injury or death could result.
1. Shake the seatback slightly to confirm
that it is securely locked into place.
It is possible to check ...
