D When starting the engine, do not use the key in
proximity with other transponder keys (including
keys of other vehicles), and do not press other key
plates against the key grip. Doing so may prevent the
engine from starting, or may cause the engine to stop
soon after it starts. If this happens, remove the key
once and then insert it again after taking off other
transponder keys (including keys of other vehicles)
from the ring or while gripping or covering them with
your hand to start the engine.
