Driver Information Center (DIC) Messages
These messages will appear if there is a problem sensed
in one of your vehicle's systems. Vehicles that are first
sold in Canada will have a number after each message.
This number helps to identify the problem. You must
then press INFO or INFO RESET to clear the display
screen for further use. However, be sure to take any
message that appears on the display screen seriously
and remember that pressing the INFO or INFO RESET
button will only make the message disappear, not
the problem.
DIC messages can also be displayed in French, German,
Spanish and Japanese. Contact your dealer to have the
language display adjusted for your vehicle.
BATTERY NOT CHARGING
- 7: This message will
appear if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.BATTERY SAVER ACTIVE
- 27: This message
is displayed when the vehicle has detected that the
battery voltage is dropping beyond a reasonable point.
The battery saver system will start reducing certain
features of the vehicle that you may not be able to
notice. At the point that features are disabled, this
message is displayed. It means that the vehicle is trying
to save the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.
BATTERY VOLTAGE HIGH
- 8: This message
shows that the electrical charging system is
overcharging (more than 16 volts). To avoid being
stranded, have the electrical system checked by your
dealership. You can reduce the charging overload by
using the accessories. Turn on the lamps and radio, set
the climate control on AUTO and the fan speed on HI,
and turn the rear window defogger on. You can monitor
battery voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts when the engine
is running.

2-101
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground with
the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick.
Prior to checking the oil level, be sure the engine has
been off for a few minutes and your vehicle is on a
level surface. Then check the dipstick and add oil if
necessary. See ªEngine Oilº in the Index.
CHECK TIRE PRESSURE
- 144: This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button
up or down the DIC display will show which tire or tires
do not have the correct inflation pressure. A ªLOW TIREº condition exists when the tire's air
pressure is under 24 psi (165 kPa) and a ªHIGH TIREº
condition exists when the tire's air pressure is above
36 psi (248 kPa).
The system will display the air pressure, the tire location
(LF, RF, RR or LR) and if the air pressure is low or
high. The tire pressure information is available in
English or metric measurements. For example, a driver's
side front tire that is low may be shown as: 22 PSI LF
TIRE LOW.
The correct tire inflation pressure should be set to those
shown on the Tire Loading
-Information Label, located on
the rear edge of the driver's door. For more information
regarding proper tire inflation, see ªInflation
-- Tire
Pressureº in the Index. If a tire is low, you should stop
as soon as possible and inspect your tire(s) for damage.
If a tire is flat, see ªIf a Tire is Flatº in the Index.

2-103
ENGINE HOT-AC OFF - 16: This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to

entry transmitters 1 or 2 are used to enter the vehicle or
buttons 1 or 2 on the driver's door are pressed.

2-115
Use this system as an aid to help you in seeing objects
beyond the headlamps. Do this by occasionally glancing
at the image as you would a rearview mirror. Do not
stare at the image.
The Night Vision System can be operated if:

The brightness control is in any position except OFF

it is dark enough outside,

the headlamps or fog lamps (if equipped) are on and

the ignition is turned to ON.The controls are located to the left of and below the
steering wheel. They are used to adjust the brightness
and location of the image. Adjust the IMAGE control so
the image is as low as possible while remaining visible.
Slide the dimmer control until the image is no brighter
than necessary to clearly and comfortably see the image.
When the system comes on, you'll see the Night Vision
System symbol in the image. After about one minute,
you should see the view of the road ahead. If you don't
see the image after about two minutes (on cold days it
may take longer for the image to display), there may
be something wrong with the system. See your dealer
for service.
CAUTION:
If the Night Vision System image is too bright,
or too high in your field of view, it may take you
more time to see things you need to see when it's
dark outside. Be sure to keep the image dim and
placed low in your field of view.

Ultrasonic Rear Parking Assist
(URPA) (Option)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
The URPA display is
located inside the vehicle,
above the rear window.
It has three color
-coded
lights that can be seen
through the rearview mirror
or by turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses how
close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When shifting into REVERSE (R) and an
object is detected, one of the following will occur:

2-119
A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the rear
sensors to recognize an object, it must be within
operating range.
If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash red if the ultrasonic
sensors are not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or the
system may not work properly. If after cleaning the rear bumper and driving forward at
least 15 mph (25 km/h), the display continues to flash
red, see your dealer. It may also flash red if your vehicle
is moving in REVERSE (R) at a speed greater than
3 mph (5 km/h). Other conditions that may affect
system performance include things like the vibrations
from a jackhammer or the compression of air brakes
on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.
