moving the ventilator slide and/or ventilator as-
semblies.
Open or close the ventilators
1by using the dial.

WARNING
●The air conditioner cooling function op-
erates only when the engine is running.
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
●Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.

sired position.
Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
●After parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
●The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
●A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air
is cooled rapidly. This does not indicate a
malfunction.
●If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

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 inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing 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 details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
●A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
●A sturdy, flat board to be placed under the
jack to give it firm support.
●A shovel to dig the vehicle out of snowdrifts.
●Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
●Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.

WARNING
●Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
●The spare tire is designed for emer-
gency use. See specific instructions un-
der the heading “Wheels and tires” in
the “Maintenance and do-it-yourself”
section of this manual.To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
WARNING
●If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
●Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
●Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
●Keep battery out of the reach of
children.
●The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle.●Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
●Do not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
●Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
●If the battery of a vehicle equipped with
the Intelligent Key system is dis-
charged, the ignition switch cannot be
moved from the LOCK position, even
using the mechanical key or the valet
key. Connect the jumper cables to an-
other vehicle, as in the case of a dis-
charged battery, and then the ignition
knob can be moved from the LOCK po-
sition. Then, jump start the vehicle.
