Emission Control System Warranty
Details of these warranties may be found with
other vehicle warranties in your Warranty Infor-
mation Booklet which comes with your NISSAN
vehicle. If you did not receive a Warranty Informa-
tion Booklet, or it is lost, you may obtain a re-
placement by writing to:
cNissan Canada Inc.
5290 Orbitor Drive
Mississauga, Ontario, L4W 4Z5If you believe that your vehicle has a de-
fect which could cause a crash or could
cause injury or death, you should immedi-
ately inform the National Highway Traffic
Safety Administration (NHTSA) in addi-
tion to notifying NISSAN.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot be-
come involved in individual problems be-
tween you, your dealer, or NISSAN.
To contact NHTSA, you may call the Auto
Safety Hotline toll-free at 1-888-327-
4236. You may also write to: NHTSA,
U.S. Department of Transportation,
Washington, D.C. 20590. You can also
obtain other information about motor ve-
hicle safety from the Hotline.
You may notify NISSAN by contacting our
Consumer Affairs Department, toll-free, at
1-800-NISSAN-1.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” 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 patterns. 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. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Turn the ignition switch ON 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
9not ready9. If the MIL does not blink after 20
seconds, the I/M test condition is9ready.9If the
MIL indicates the vehicle is in a9not ready9con-
dition, drive the vehicle through the following
pattern to set the vehicle to the ready condition. If
you cannot or do not want to perform the driving
pattern, a NISSAN dealer can conduct it for you.
