Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have
the advantages of SH-AWD. Have
your vehicle checked by a dealer
as soon as possible.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is problem
with the SH-AWD system.
If the SH-AWD indicator blinks while
driving, it indicates the dif f erential
temperature is too high. You will also
see an ‘‘SH-AWD DIFF TEMP.
HIGH’’ message on the multi-
inf ormation display. If this happens,
pull to the side of the road when it is
saf e, shif t to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it checked.
