of the center floor console.
The outlet is powered when the
ignition is in ON/RUN or ACC/

door is opened within 10 minutes of
turning off the vehicle. See Retained
Accessory Power (RAP) on
page 9‑24.

5-32 Instruments and Controls
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
If You Cannot See the HUD
Image When the Ignition Is On
.Is anything covering the
HUD lens?
.Is the HUD dimmer setting bright
enough?
.Is the HUD image adjusted to
the proper height?
.Are you wearing polarized
sunglasses?
.Still no HUD image? Check the
fuse in the instrument panel fuse
block. SeeInstrument Panel
Fuse Block on page 10‑40.
If the HUD Image Is Not Clear
.Is the HUD image too bright?
.Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer.
Keep in mind that the windshield is
part of the HUD system.
Vehicle Messages
Messages displayed on the DIC
indicate the status of the vehicle or
some action that may be needed to
correct a condition. Multiple
messages may display one after the
other.
The messages that do not require
immediate action can be
acknowledged and cleared by
pressing SET/CLR. The messages
that require immediate action cannot
be cleared until that action is
performed. All messages should be
taken seriously and clearing the
messages does not correct the
problem.
The following are some of the
vehicle messages that may be
displayed depending on your
vehicle content.

The electrical cord is located on
the passenger side of the engine
compartment, between the
fender and the air cleaner on
