Outside Air Temperature Indicator Calibration
The outside temperature sensor is located behind the
center of the front bumper. The gauge control module
(tach) uses measurements from this sensor to display
the outside air temperature.
Because of the location of the sensor, it may be affected
by heat reflection from the road, engine and radiator
heat or hot exhaust from surrounding traffic.
These conditions can heat soak the outside air
temperature sensor and cause inaccurate readings.
Logic has been written into the gauge control module
(tach) to help prevent abnormal or fluctuating outside
air temperature indicator readings.
Initial outside air temperature indication after the
ignition switch is turned to ON (II).
 If the engine coolant temperature is 60 °C (140 °F) or higher when the ignition switch is turned to ON (II),
the outside air temperature indicated the last time the
key was turned off will be displayed regardless of the
current temperature measured by the outside air
temperature sensor.
 If the engine coolant temperature is 59 °C (139 °F) or lower when the ignition switch is turned to ON (II), the
current temperature measured by the outside air
temperature sensor will be indicated. If the temperature measured by the outside air
temperature sensor is greater than the temperature on
the outside air temperature indicator, the outside air
temperature indicator will increase by 1 °C (1.8 °F) per
minute after the vehicle speed is greater than 30 km/h
(19 mph) for more than 1 minute and 30 seconds. It will
continue to increase until the current outside air
temperature is indicated. So, the first change to the
outside air temperature indicator is 1 minute and
30 seconds after the vehicle speed is greater than
30 km/h (19 mph). If the vehicle speed drops below
30 km/h (19 mph), the indicator will not update again
until the vehicle speed is increased to 30 km/h (19 mph)
or more for more than 1 minute and 30 seconds again.
If the outside air temperature is less than the indicated
temperature, the temperature will decrease 1 °C every
2 seconds (1 °F
every 1.1 seconds) until the current
outside air temperature is indicated regardless of
vehicle speed.
If the indicator displays ‘‘ ’’ for more than 2
seconds after selecting the outside air temperature
display mode, check the outside air temperature sensor
(see page 21-68), or gauge control module self-
diagnosis (see page 22-241).

General Operation
Anti-theft Feature
Symptom DiagnosisSelf-Inertial Navigation Limitations
23-90Navigation System
General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
 Disconnecting the battery
 Disconnecting the navigation unit A (17P) and C (12P) connector
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box
After service, reconnect power to the navigation unit,
and turn the ignition switch ON (II). Enter the 4-digit
anti-theft security codes, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing clients
about symptoms of the navigation system. The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause some discrepancies between
the vehicle’s actual position and the indicated vehicle
position (GPS vehicle position).
The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface.
– Driving with snow chains mounted.
– Abnormal tire pressure.
– Incorrect tire size.
– Frequent lane changes across a wide highway.
– Continuous driving on a straight or gently curving highway.
 Tolerances in the system and map inaccuracies will sometimes limit how precisely the vehicle position is
indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible).
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage.
– Driving on a road with a series of sharp hair-pin turns.
– Driving near a gradual highway exit or transition.
– Driving on one of two close parallel roads.
– Making many 90 degree turns.
– The direction to destination icon or the destination icon shown or the map may be up to several
hundred feet away from the actual location.

The GPS cannot detect the vehicle’s position during the
following conditions: Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems.
The accuracy of the GPS is reduced during these
instances:  Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems. Whenever the navigation system is giving guidance,
the front speakers are muted. When the voice control
system is being used, all of the speakers are muted.
 In cold temperatures, the display may stay dark for the first 2 or 3 minutes until it warms up.
 When the display is too hot because of direct summer sunlight, it will remain dark until the temperature
drops.
 When the humidity is high and the interior temperature is low, the display may appear cloudy.
The display will clear up after some use.
 Fingerprints on the touch panel may sometimes be noticeable because of the panel’s low-reflection
coating. Clean the screen with a soft damp cloth. You
may use a mild cleaner intended for eye glasses or
computer screens. To avoid scratching the panel, do
not rub too hard, or use abrasive cleaners, or shop
towels.
 The touch panel consists of a touch sensitive resistive membrane covering the display. Unlike previous
systems, you must actually touch the display to
activate it. Never use hard or sharp implements to
operate the screen because you risk damaging the
sensing membrane. If a touch switch does not
function immediately, shift your finger slightly, and
touch it again.
