blinks at a low speed.
(When the Idling Stop System indica-
tor blinks at a high speed (twice ap-
proximately every 1 second), be sure to
check if the engine hood is open. When
the engine hood is opened the engine
will be in the normal stopped state. In
this case, restart the engine with the
ignition switch).
(When the Idling Stop System indicator
blinks at a low speed (once approxi-
mately every 2 seconds), have the sys-

high.
•
When the battery is replaced or the bat-
tery terminal is disconnected for ex-
tended periods and then reconnected.

When the Idling Stop System indicator
illuminates, the engine starts running
automatically under at least one of the
following conditions:
• The driver’s seat belt is unfastened, or
the driver’s door is open.
• The battery voltage becomes low (due
to electrical load from other vehicle
systems like headlights, heaters, etc.,
or auxiliary devices connected to the

•When the temperature inside the ve-
hicle is lower than approximately 68°F
(20°C).
• When the temperature inside the ve-
hicle is higher than approximately 86°C
(30°F). (When the air conditioner is off,
the Idling Stop System will operate.)

• When more than 3 minutes have
elapsed since the Idling Stop System
was active.
• When the accelerator pedal is
depressed.
• When the steering wheel is operated.
(The steering wheel operation may be-
come heavy, but this is not a
malfunction.)
• When the battery capacity is low.
• When the power consumption is high.
• When the shif t lever is any range other
than D (Drive).
• When the Idling Stop OFF switch is
pushed.NOTE:
The following condition will prevent the
Idling Stop System from automatically
restarting the engine. Starting the en-
gine with the ignition switch operation is
then necessary:
• The hood is open.
Use this system while waiting at a stop
light, etc. When the vehicle is stopped for
long periods of time, turn off the engine.
When the engine is stopped by the Idling
Stop System, heating, cooling and dehu-
midif ying functions will be deactivated. To
avoid the air conditioning functions from
being deactivated, turn off the Idling Stop
System by pushing the Idling Stop OFF
switch.
RETROGRADE MOVEMENT
CONTROL FUNCTION
This system is designed to reduce the ret-
rograde movement that occurs while the
driver’s foot changes from depressing the
brake pedal to the accelerator pedal when
moving the vehicle while the Idling Stop
System is active on a hilly road.
IDLING STOP SYSTEM DISPLAY
The status of the Idling Stop System can be
checked in the vehicle information display.
Starting and driving5-131

The indicator is displayed when the Idling
Stop System is activated.If the Idling Stop System is activated or de-
activated using the Idling Stop OFF switch,
the message is shown.The fuel saved and the engine stop time
mode shows the following items:
• The fuel saved shows the estimated
quantity of fuel that was saved by the
Idling Stop System every time the engine
is automatically stopped.
• The engine stop time shows the time that the engine has been stopped for by
the Idling Stop System.
The total fuel saved and the engine stop
time can also be checked in the vehicle infor-
mation display. For additional information,
see “Vehicle information display” (P. 2-22).

• When the Idling Stop System is deacti-vated af ter the engine has been auto-
matically stopped by the Idling Stop Sys-
tem, the engine will immediately restart if
suitable conditions are present. The en-
gine will then be prevented from auto-
matically stopping during the same
journey.
NOTE:
•The Idling Stop System ON or OFF mes-
sage is displayed for a few seconds in
the vehicle information display when
the Idling Stop System OFF switch is
pushed. For additional information, see
“Idling Stop System Display ” (P. 5-131).
• The Idling Stop System resets to ON every time the ignition switch is
switched from the OFF position to the
ON position.
• It is best to disable the ISS system when towing a trailer. You can do this
by pushing the Idling Stop OFF switch.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob (if so equipped).
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-6).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-16).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-7).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, see “Tire chains” (P. 8-40).
COLD WEATHER DRIVING
5-134Starting and driving

3. Get out of the vehicle. Look and listen forsteam or coolant escaping from the ra-
diator before opening the hood. If steam
or coolant is escaping, turn off the en-
gine. Do not open the hood further until
no steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time. 6. Af ter the engine cools down, check the
coolant level in the engine coolant res-
ervoir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit
a NISSAN dealer for this service. When towing your vehicle, all jurisdictional
and local regulations for towing must be
followed. Incorrect towing equipment
could damage your vehicle. Towing in-
structions are available from a NISSAN
dealer. Local service operators are gener-
ally familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, NISSAN recommends hav-
ing a service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle af ter it
has been lif ted by a tow truck.
CAUTION
• When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-
tion. Use dollies or flatbed if any of
the listed systems are not working.
• Always attach safety chains before
towing.
