Thebutton will be on the NISSAN Intelli-
gent Key® if the vehicle has remote engine start.
This feature allows the engine to start from out-
side the vehicle.
The following features may be affected when the
remote start feature is used:
● Vehicles with a manual climate control sys-
tem will default to the last used heating or
cooling mode. ●
Vehicles with an automatic climate control
system will default to either a heating or
cooling mode depending on outside and
cabin temperatures. For additional informa-
tion, refer to “Remote start logic” in the
“Monitor, climate, audio, phone and voice
recognition systems” section of the manual.
● Vehicle equipped with heated seats may
have this feature come on during a remote
start. For additional information, refer to
“Heated seats” in the “Instruments and con-
trols” section of the manual.
Laws in some local communities may restrict the
use of remote starters. For example, some laws
require a person using remote start to have the
vehicle in view. Check local regulations for any
requirements.
Other conditions may affect the function of the
Remote Engine Start feature. For additional infor-
mation, refer to “Conditions the remote start will
not work” in this section of the manual.

4-28Monitor, climate, audio, phone and voice recognition systems

●After parking in the sun, drive for 2 or 3 min-
utes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
● The air conditioning system should be

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.

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
much harder to operate. Have the power
steering system checked by a NISSAN
dealer.
The power steering system is designed to pro-
vide power assistance while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still per-
formed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the igni-
tion switch to the OFF position. The temperature of the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to over-
heat.
You may hear a noise from the front of the vehicle
when the steering wheel is operated. This is a
normal operational noise and is not a malfunction.
If the power steering warning light illuminates
while the engine is running, it may indicate the
power steering system is not functioning properly
and may need servicing. Have the power steering
system checked by a NISSAN dealer.
When the power steering warning light illumi-
nates with the engine running, the power assist
for the steering will cease operation but you will
still have control of the vehicle. At this time,
greater steering efforts are required to operate
the steering wheel, especially in sharp turns and
at low speeds.
POWER STEERING
Starting and driving5-31

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance. This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels.
BRAKE SYSTEM
5-32Starting and driving

●Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
6. Start the engine of the booster vehicle and let it run for a few minutes.
7. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to
4 seconds before trying again.
8. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
CAUTION
●Do not push start this vehicle. The 3-way
catalyst may be damaged.
● Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage. If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
WARNING
●
Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
● Do not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.
