— When replacing tires, install the
specified size of tires on all four
wheels.
— When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the “9.
Technical and consumer informa-
tion” section of this manual.

this manual.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the systemhelps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the systemDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Self-test featureThe ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does not indicate
a malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates theABS warning light on the instrument panel. The
brake system then operates normally, but with-
out anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operationThe ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.

On slippery surfaces such as wet asphalt roads,
vehicle wheels may spin when the vehicle is
accelerated. This wheel spin reduces accelera-
tion, or causes the vehicle to swerve, thus
decreasing vehicle stability.
When the vehicle drive wheels begin to spin, the
Traction Control System (TCS) controls the
engine torque using an electronic control sys-
tem, and it also controls automatic control shift-
ing if necessary (for automatic transmission
models). This reduces spinning of the drive
wheels, and result in improved vehicle accelera-
tion performance. It also improves the vehicle
stability by swerving motion.

When the TCS is operating, the “SLIP” indi-
cator light in the meter panel blinks.

If the “SLIP” indicator light blinks, the vehicle
is under slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Trac-
tion Control System (TCS) off indicator light”
in the “2. Instruments and controls” section.

Indicator light
If a malfunction occurs in the TCS, the “SLIP”
and “TCS OFF” indicator lights come on in
the instrument panel. As long as these indi-
cator lights are illuminated, the traction con-
trol function (except the ABS) is canceled.
The vehicle will behaves like a model without
the TCS.
WARNING
The traction control system is designed
to prevent the wheels from spinning.
However, it does not prevent vehicle
slipping or spinning due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Be especially careful when driving on
slippery surfaces and always drive
safely.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the braking
and engine output to help improve vehicle sta-
bility.

When the VDC system is operating, the
“SLIP” indicator in the instrument panel
blinks.

If the “SLIP” indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. See “Slip indicator
light”, and “Vehicle Dynamic Control (VDC)
OFF indicator light” in the “2. Instruments and
controls” section.

Indicator light
If a malfunction occurs in the system, the
“SLIP” and “VDC OFF” indicator lights illumi-
nate in the instrument panel. As long as these
indicators are illuminated, the VDC system
function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) system to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other driving
wheel. If the vehicle is operated with the VDC

TIRE PRESSURE MONITORING
SYSTEM (TPMS)This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. 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 (in the meter panel).
This system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h). For
more details, refer to “Warning/indicator lights
and audible reminders” in the “2. Instruments
and controls” section and “Tire pressure moni-
toring system (TPMS)” in the “5. Starting and
driving” section.
WARNING

If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as pos-
sible. Driving with under-inflated
tires may permanently damage thetires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure
for all four tires. Adjust the tire pres-
sure to the recommended COLD tire
pressure shown on the Tire and
Loading Information label to turn the
low tire pressure warning light OFF.
If you have a flat tire, replace it with a
spare tire as soon as possible.

When a spare tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on after 1 minute. Contact your
NISSAN dealer as soon as possible
for tire replacement and/or system
resetting.

Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CHANGING A FLAT TIREIf you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Shift the manual transmission into R
(Reverse) position (automatic transmission in
P (Park) position).
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic
and clear of the vehicle.

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light or light switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be certain a vehicle maintains a level position
when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
unusual nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
these conditions.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be certain your rear view mirrors conform to
all federal, state and/or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive a vehicle at a moderate speed.
Some states or provinces have specificspeed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if a vehicle is equipped with automatic
transmission, first apply the parking brake
and block the wheels, and then move the
transmission selector lever into the P (Park)
position. If you move the selector lever to the
P (Park) position before blocking the wheels
and applying the parking brake, the transmis-
sion may get damaged.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
