BASIC OPERATION
VEHICLE MARK
SymptomCause Remedy
No image is shown. Display brightness adjustment is set fully to
DARK side. Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle
is driving on a dark pink route.
System is not malfunctioning.
Screen is too dark.
Motion of the image is too slow. Temperature inside the vehicle is low.
Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display (dis-
play unit). System is not malfunction.
Symptom
Cause Remedy
Map screen and BIRDVIEW ™
Name of the place varies with the
screen. Some thinning of the character data is done to
prevent the display becoming to complex. In
some cases and in some locations, the display
contents may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing. System is not malfunctioning.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the
“SWITCH
SCREENS ” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function. Perform screen dimming and select the
nighttime screen by
“SWITCH SCREENS ”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed.
Press “MAP ” button to display the current
location.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP ” button to display the current
location.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the
vehicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument
panel. Do not place anything in the center on top of
the display.
GPS satellites are not visible from current loca-
tion. Wait until GPS satellites are visible by mov-
ing the vehicle.
Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark) on the map screen stays gray. Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.) As a rule, an updated map DVD
–ROM will
be released once a year.

WARNING:

Never get under the vehicle while it is supported only by the jack. Always use safety stands to
support the frame when you have to get under the vehicle.

Place wheel chocks at both front and back of the wheels on the ground.
CAUTION:

All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.

It is necessary to use proper towing equipment to avoid possible damage during towing opera-
tion. Towing is in accordance with Towing Procedure Manual at dealer.

Always attach safety chains before towing.

When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.

Never tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:

When towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place
the ignition key in the LOCK position. This will result in
damage to the steering lock mechanism.

4WD MODELS
INFINITI does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:

Never tow 4WD models with any of the wheels on the
ground as this may cause serious and expensive damage
to the transfer case and transmission.
To w i n g P o i n t
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ

Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.

Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.

The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.

Always pull the cable straight out from the front or rear of the vehicle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
