WARNING LIGHTS
orBrake warning
light (red)
This light functions for both the parking
brake and the foot brake systems.
Parking brake indicator (if so equipped)
When the ignition switch is placed in the ON
position, the light comes on when the park-
ing brake is applied.
Low brake fluid warning light
When the ignition switch is placed in the ON
position, the light warns of a low brake fluid
level. If the light comes on while the engine is
running with the parking brake not applied,
stop the vehicle and perform the following:
1. Check the brake fluid level. Add brake
fluid as necessary. For additional infor-
mation, refer to “Brake fluid” in the “Do-
it-yourself ” section of this manual.2. If the brake fluid level is correct, have
the warning system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.

∙ Make sure the area around the vehicle isclear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, and windshield-
washer fluid as frequently as possible,
or at least whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust headrests/head restraints.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is pushed to
the ON position. For additional informa-
tion, refer to “Warning lights, indicator
lights and audible reminders” in the “In-
struments and controls” section of this
manual. 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N
(Neutral). P (Park) is recommended.
The starter is designed not to oper-
ate if the shif t lever is in any of the
driving positions.
3. Push the ignition switch to the ON po- sition. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
∙ If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch
to the ON position to start cranking
the engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition switch to the LOCK position. Af ter
cranking the engine, release the ac-
celerator pedal. Crank the engine
with your foot off the accelerator
pedal by depressing the brake pedal
and pushing the ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above pro-
cedure.

WARNING
If the shif t lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and
others.
Drive sport mode switch
When the drive sport mode switch is
pushed with the shif t lever in the D (Drive)
position, the drive sport mode indicator in
the instrument panel illuminates. For addi-
tional information, refer to “Drive sport
mode indicator” in the “Instruments and
controls” section of this manual.
Use the drive sport mode when you need
improved engine braking.
To turn off the drive sport mode, push the
drive sport mode switch again. The drive
sport mode indicator will turn off.Each time the engine is started, or when
the shif t lever is shif ted to any position
other than D (Drive), the drive sport mode
will automatically turn off.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-
peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.

– When the vehicle’s traveling direc-tion does not align with the lane
marker.
– When traveling close to the vehicle in front of you, which obstructs the
lane camera unit detection range.
– When rain, snow or dirt adheres to the windshield in front of the lane
camera unit.
– When the headlights are not bright due to dirt on the lens or if the aim-
ing is not adjusted properly.
– When strong light enters the lane camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
– When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions: ∙ When you operate the lane change sig- nal and change the traveling lanes in
the direction of the signal. (The I-LI sys-
tem will be deactivated for approxi-
mately 2 seconds af ter the lane change
signal is turned off.)
∙ When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the warning and assist func-
tions will resume.
Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional): ∙ When the brake pedal is depressed.
∙
When the steering wheel is turned as far as
necessary for the vehicle to change lanes.
∙ When the vehicle is accelerated during I-LI system operation. ∙ When the Intelligent Cruise Control (ICC)
approach warning occurs.
∙ When the hazard warning flashers are operated.
∙ When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, the I-LI system
will be turned off automatically. ∙ “Not Available Poor Road Conditions”: When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
∙ “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the I-LI system. Push the ProPILOT
Assist switch (for vehicles with ProPILOT
Assist) on the steering wheel again to turn
the I-LI system back on.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pres-
sure Monitoring system (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit, and the “Tire Pressure Low - Add Air”
warning appears in the vehicle information
display, one or more of your tires is signifi-
cantly under-inflated. If equipped, the sys-
tem also displays pressure of all tires (ex-
cept the spare tire) on the display screen by
sending a signal from a sensor that is in-
stalled in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will ac-
tivate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.

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 P (Park). Switch off all unneces-
sary electrical systems (lights, heater,
air conditioner, etc.).
3. Place the ignition switch in the LOCK position.
4. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
