Be sure to continue scanning the
displays, controls, and driving
environment just as you would in a
vehicle without HUD. If you never
look at the instrument panel cluster,
you may miss something important,
such as a warning light. Under
important warning conditions, the
CHECK GAGES warning will
illuminate in the HUD. View your
Driver Information Center (DIC) for
more information.
The HUD controls are located to the
left of the steering wheel.
To adjust the HUD so it can be seen
properly, do the following:
1. Start the engine and press the HUD dimmer control all the way
up by pressing the (+) button.
The brightness of the HUD
image is determined by the light
conditions in the direction the
vehicle is facing and where you
have the HUD dimmer control
set. If you are facing a dark
object or a heavily shaded area, the HUD may anticipate that you
are entering a dark area and
may begin to dim.
It is possible for sunlight to enter
the HUD making it difficult to see
the image. The display will
return to normal when the
sunlight is no longer entering
the HUD.
2. Adjust the seat to a comfortable driving position. If your seat
position changes, the HUD may
need to be re-adjusted.
3. Press the up or down arrows to center the HUD image in
your view.
The HUD image can only be
adjusted up and down, not side
to side.
4. Press the dimmer control downward until the HUD image
is no brighter than necessary.
To turn HUD off, press and hold
the (–) button until the HUD display
turns off.

The following conditions may
cause this message to appear.
.Driver-added equipment plugged
into the accessory power outlet
on the center console is causing
interference. Examples of these
devices are cell phones and cell
phone chargers, two-way radios,
power inverters, or similar items.
Try moving the RKE transmitter
away from these devices when
starting the vehicle. In addition,
PDA devices and remote garage
and gate openers may also
generate Electromagnetic
Interference (EMI) that may
interfere with the RKE
transmitter. Do not carry the
RKE transmitter in the same
pocket or bag as these devices.
.The vehicle is experiencing
Electromagnetic
Interference (EMI). Some
locations, such as airports,
automatic toll booths, and some
gas stations have EMI fields
which may interfere with the
RKE transmitter.
If moving the transmitter to
different locations within the
vehicle does not help, place the
transmitter in the glove box
transmitter pocket with the
buttons facing to the right and
then press the START button.
.The vehicle's battery voltage is
low. The battery voltage must be
above 10 volts for the RKE
transmitter to be detected
properly.
NO FOB - OFF OR RUN?
This message displays when the
RKE transmitter is not detected
inside the vehicle while you are
trying to turn the ignition off. The

vehicle is turned off or is restarted,
or five minutes has expired. If you
turn the ignition off and you cannot
find the RKE transmitter, you will not
be able to restart the vehicle. The
RKE transmitter needs to be inside
the vehicle in order for the vehicle to
start. SeeStarting the Engine on

This message displays and
four chimes sound if the
transmission fluid temperature
rises above 132°C (270°F) or rises
rapidly. The transmission may
shift gears or apply the torque
converter clutch to reduce the fluid
temperature. Driving aggressively or
driving on long hills can cause the
transmission fluid temperature to be
higher than normal. If this message
appears, you may continue to drive
at a slower speed. Monitor the
transmission fluid temperature and
allow it to cool to at least 110°C
(230°F). The transmission fluid
temperature can be monitored with
the gauges button on the DIC. See
“DIC Operation and Displays” under
Driver Information Center (DIC) on
page 5‑28 andAutomatic
