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 com- muting and coast whenever possible.
2. Maintain Constant Speed
• Look ahead to try and anticipate and minimize stops.
• Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
• Maintaining a steady speed can mini- mize 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
Distances
• Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
• Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
• Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
• Select a gear range suitable to road conditions.
5. Use Cruise Control
• Using cruise control during highway driving 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 determine 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 stop-
ping 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 ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing 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
5-108Starting and driving

Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.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. 8-4).
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. 8-14).
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. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide 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. 8-38).
COLD WEATHER DRIVING
Starting and driving5-129

•Whenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial 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
serious injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to touch. 2. Apply the parking brake. Move the shif t
lever to the P (Park). Switch off all unnec-
essary electrical systems (lights, heater,
air conditioner, etc.).
3. Place the ignition switch to the LOCK or OFF position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).

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.

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not
necessary.
WARNING
• Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator
cool down. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator. For additional
information on precautions, see “If
your vehicle overheats” (P. 6-13).
• The radiator and coolant reservoir
are equipped with a pressure type ra-
diator cap. To prevent engine dam-
age, use only a Genuine NISSAN ra-
diator cap.
CAUTION
• Never use any cooling system addi-
tives such as radiator sealer. Addi-
tives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling system.
• When adding or replacing coolant, be
sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum an-
tifreeze protection to -34° F (-37° C).
The use of other types of coolant so-
lutions other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent may damage the en-
gine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
(or equivalent coolant), including
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the
use of non-distilled water may re-
duce the life expectancy of the
factory-fill coolant. For additional in-
formation, see the "Maintenance and
schedules" section of this manual.
