WARNING
• Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be lef t alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot, sunny
days, temperatures in a closed ve-
hicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces power efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately oneminute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Additional information
• When replacing a wheel without the
TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of the
spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

Seat belts help reduce the risk of injury in
collisions 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
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. 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 ac- celerator pedal to gradually slow the
vehicle. 5. If there is nothing in the way, steer the
vehicle to follow the road while the ve-
hicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until the 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 appropriate 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 han-
dling and stability of the vehicle, especially
at highway speeds. Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, refer
to “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 vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
•
The vehicle generally moves or pulls
in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering
wheel.
5-8Starting and driving

4. Push the power switch while depressingthe brake pedal within 10 seconds af ter
the chime sounds. The power switch
position changes to the READY to drive
mode.
Af ter step 3 is performed, if the power
switch is pushed without depressing the
brake pedal, the power switch position will
change to ACC.
NOTE:
• When the power switch is pushed to the ACC or ON position or READY to
drive mode by the above procedure,
the EV system operation for dis-
charged Intelligent Key system indica-
tor appears on the vehicle information
display even if the Intelligent Key is in-
side the vehicle. This is not a malfunc-
tion. To stop the warning indicator
from blinking, touch the power switch
with the Intelligent Key again.
• If the Intelligent Key battery discharge indicator appears on the vehicle infor-
mation display, replace the battery as
soon as possible. For additional infor-
mation, refer to “NISSAN Intelligent
Key® battery replacement” in the
“Maintenance and do-it-yourself ” sec-
tion of this manual.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the power switch to be placed
in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle
into the READY to drive position using the
registered key, it may be due to interfer-
ence caused by another registered key, an
automated toll road device or automated
payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON posi- tion for approximately 5 seconds.
2. Place the power switch in the OFF posi- tion and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device
(which may have caused the interfer-
ence) separate from the registered key.
If this procedure allows the power
switch to be placed in the READY to drive
mode, NISSAN recommends placing the
registered key on a separate key ring to
avoid interference from other devices. • Make sure that the area around the ve-
hicle is clear.
• Check fluid levels such as coolant, brake fluid, and windshield-washer fluid as fre-
quently as possible.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position the seat and adjust the head restraints/headrests.
• Adjust the inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of the warning lights when the power switch is pushed to the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual.
