CHILD SAFETY REAR DOOR LOCK
Child safety locks help prevent the rear doors
from being opened accidentally, especially when
small children are in the vehicle.
The child safety lock levers are located on the
edge of the rear doors.
When the lever is in the LOCK position, the
door can be opened only from the outside.
WARNING
The remote keyless entry keyfob trans-
mits radio waves when the buttons are
pushed. The FAA advises radio waves may
affect aircraft navigation and communica-
tion systems. Do not operate the remote
keyless entry keyfob while on an airplane.
Make sure the buttons are not operated
unintentionally when the unit is stored for
a flight.
It is possible to lock/unlock all doors, turn the
interior light on, and activate the panic alarm by
using the keyfob from outside the vehicle.
Be sure to remove the key from the vehicle
before locking the doors.
The keyfob can operate at a distance of approxi-
mately 33 ft (10 m) from the vehicle. The effective
distance depends upon the conditions around
the vehicle.
As many as 5 keyfobs can be used with one
vehicle. For information concerning the purchase
and use of additional keyfobs, contact a NISSAN
dealer. The keyfob will not function when:
● the battery is discharged
● the distance between the vehicle and the
keyfob is over 33 ft (10 m)
The panic alarm will not activate when the
key is in the ignition switch.
CAUTION
Listed below are conditions or occur-
rences which will damage the keyfob:
● Do not allow the keyfob, which contains
electrical components, to come into
contact with water or salt water. This
could affect the system function.
● Do not drop the keyfob.
● Do not strike the keyfob sharply against
another object.
● Do not change or modify the keyfob.
● Wetting may damage the keyfob. If the
keyfob gets wet, immediately wipe until
it is completely dry.
● Do not place the keyfob for an extended
period in an area where temperatures
exceed 140°F (60°C) .

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.
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 washer fluid to refill the windshield-
washer fluid reservoir.
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.
● Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.

●Do not touch the internal circuit and electric
terminals as it could cause a malfunction.
● When changing the battery, do not let dust
or oil get on the keyfob.
● There is danger of explosion if a lithium bat-
tery is incorrectly replaced. Replace only
with the same or equivalent type.
Recommended battery: CR2025 or equivalent.
4Close the lid securely.
5. Press the

HEADLIGHTS
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. A
bulb can be replaced from inside the engine
compartment without removing the headlight as-
sembly.
CAUTION
●
High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
● When handling the bulb, do not touch
the glass envelope.
● DO NOT TOUCH THE BULB WITH BARE
HANDS.
● Use the same number and wattage as
shown in the chart.
● Do not leave the bulb out of the head-
light reflector for a long period of time
as dust, moisture and smoke may enter
the headlight body and affect the per-
formance of the headlight.
● Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact a NISSAN dealer.
