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.
NOTE: ● Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the vents. ●
When parking, set the heater and air condi-
tioner controls to turn off air recirculation to
allow fresh air into the passenger compart-
ment. This should help reduce odors inside
the vehicle.

OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally. The sunload sensor, located on the top driver’s
side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing on or around this sensor.

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops.
● Use smooth, gentle accelerator and
brake application whenever possible.
● Maintain constant speed while commut-
ing and coast whenever possible.
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops.
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops.
●
Maintaining a steady speed can minimize
red light stops and improve fuel efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
● Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag. ●
Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag.
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking.
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
● Select a gear range suitable to road con-
ditions.
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed.
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains.
6. Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time. 7.
Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy.
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing.
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
10. Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible.
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
Starting and driving5-29

The system indicatorsAwill appear when the
vehicle moves closer to an object.
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.
ANTIFREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
antifreeze to assure proper winter protection. For
additional information, refer to “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 additional information, refer to “Bat-
tery” in the “Maintenance and do-it-yourself” sec-
tion 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 additional information, refer to “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.
