To notify INFINITI of any safety con-
cerns please contact our Consumer
Information Centre toll free at
1-800-361-4792.WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may result
in transmission damage or unexpected ve-
hicle movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready con-
dition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving pat-
terns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle. If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a “not ready” condition. Be-
fore taking the I/M test, check the vehicle's
inspection/maintenance test readiness con-
dition. Place the ignition switch in the ON
position without starting the engine. If the
Malfunction Indicator Light (MIL) comes on
steady for 20 seconds and then blinks for
10 seconds , the I/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare the vehicle for testing.
