Loose fuel cap warning
This warning appears when the fuel-filler cap is
not tightened correctly after the vehicle has been
refueled. See “Fuel-filler cap” in the “Pre-driving
checks and adjustments” section.
Check tire pressure warning
This warning appears when the low tire pressure
warning light in the meter illuminates and low tire

small amount of neutral detergent with a soft
cloth. Never spray the screen with water or de-
tergent. Dampen the cloth first, and then wipe the
screen.

avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental restraint system” section of this
manual, and also instruct your passengers to do
so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
If the right side or left side wheels unintentionally
leave the road surface, maintain control of the
vehicle by following the procedure below. Please
note that this procedure is only a general guide.
The vehicle must be driven as appropriate based
on the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course. 4. When appropriate , slowly release the accel-
erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the ve- hicle to follow the road while vehicle speed
is reduced. Do not attempt to drive the ve-
hicle back onto the road surface until vehicle
speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the ap-
propriate driving lane.
● If you decide that it is not safe to return the
vehicle to the road surface based on vehicle,
road or traffic conditions, gradually slow the
vehicle to a stop in a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by maintain-
ing the correct air pressure and visually inspect the tires for wear and damage. See “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual. If a tire rapidly loses air
pressure or “blows-out” while driving, maintain
control of the vehicle by following the procedure
below. Please note that this procedure is only a
general guide. The vehicle must be driven as
appropriate based on the conditions of the ve-
hicle, road and traffic.

NOTE:
The Intelligent Key port does not charge
the Intelligent Key battery. If you see the
low battery indicator, replace the battery as
soon as possible. See “Battery replace-
ment” in the “Maintenance and do-it-
yourself” section.

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 function on
the Intelligent Key.
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 toprovide 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

SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solution.
Allow the belts to dry completely in the shade
before using them. See “Seat belt maintenance”
in the “Safety – Seats, seat belts and supplemen-
tal restraint system” section of this manual.
