the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-9) for wheel off-set
dimensions.
. Since the spare tire is not
equipped with the TPMS, 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 ap-
proximately 1 minute. The light
will remain on after 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as possible. It is recommended you
visit a NISSAN dealer for these
services.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning. .
The use of retread tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias,
bias-belted or radial), and tread
pattern on all four wheels. Failure
to do so may result in a circum-
ference difference between tires
on the front and rear axles which
will cause excessive tire wear and
may damage the transmission,
transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,

9-4Maintenance and schedules
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate
properly and that the wipers do not
streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example,
each time you check the engine oil or
refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1.
Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in- spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
4) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
may accumulate. For additional informa-

Pre-towing tips
.Be certain your vehicle maintains a
level position when a loaded or un-
loaded trailer is hitched. Do not drive
the vehicle if it has an abnormal nose-
up or nose-down condition; check for
improper tongue load, overload, worn
suspension or other possible causes
of either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center
of gravity low.
. Load the trailer so approximately 60%
of the trailer load is in the front half
and 40% is in the back half. Also make
sure the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light op-
eration, and trailer wheel lug nuts
every time you attach a trailer to the
vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
clearance is known.
Trailer towing tips
In order to gain skill and an understand-
ing 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 perfor-
mance will be somewhat different than
under normal driving conditions.
.Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a
pin or lock to prevent the coupler from
inadvertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moder-
ate speed. Some states or provinces
have specific speed 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:
CAUTION
If you move the shift lever to the P
(Park) position before blocking the
wheels and applying the parking
brake, transmission damage could
occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until
the blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO
position and the Automatic Transmis-
sion (AT) park warning light is turned
off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.

2. Start the engine.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle andtrailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
. While going downhill, the weight of the
trailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce
your speed and shift to a lower gear.
Avoid long or repeated use of the
brakes when descending a hill, as this
reduces their effectiveness and could
cause overheating. Shifting to a lower
gear instead provides “engine braking”
and reduces the need to brake as
frequently.
. If the engine coolant temperature
rises to a high temperature, see “If
your vehicle overheats” (P.6-14).
. Trailer towing requires more fuel than
normal circumstances.
. Avoid towing a trailer for your vehicle’s
first 500 miles (800 km).
. Have your vehicle serviced more often
than at intervals specified in the
recommended maintenance schedule
shown in the "9. Maintenance and schedules" section.
. When making a turn, your trailer
wheels will be closer to the inside of
the turn than your vehicle wheels. To
compensate for this, make a larger
than normal turning radius during the
turn.
. Crosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be
prepared for possible changes in
crosswinds that could affect vehicle
handling.
Do the following if the trailer begins to
sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast
and steer as straight ahead as the
road conditions allow. This combina-
tion will help stabilize the vehicle.
.Do not correct trailer sway bysteering or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side
of the road in a safe area.
3. Try to rearrange the trailer load so it is balanced as described earlier in this
section.
. Be careful when passing other vehi-
cles. Passing while towing a trailer requires considerably more distance
than normal passing. Remember the
length of the trailer must also pass the
other vehicle before you can safely
change lanes.
. Use the Tow mode or downshift the
transmission to a lower gear for en-
gine braking when driving down steep
or long hills. This will help slow the
vehicle without applying the brakes.
. Avoid holding the brake pedal down
too long or too frequently. This could
cause the brakes to overheat, result-
ing in reduced braking efficiency.
. Increase your following distance to
allow for greater stopping distances
while towing a trailer. Anticipate stops
and brake gradually.
. NISSAN recommends that the cruise
control not be used while towing a
trailer.
. While towing a trailer, do not use the
following systems (if so equipped):
— the Lane Departure Warning (LDW)
system
(See “How to enable/disable the
LDW system” (P.5-28).)
— the Intelligent Lane Intervention (I- LI) system
(See “How to enable/disable the I-LI
system” (P.5-34).)

. Some states or provinces have speci-
fic regulations and speed limits for
vehicles that are towing trailers. Obey
the local speed limits.
. Check your hitch, trailer wiring har-
ness connections, and trailer wheel
lug nuts after 50 miles (80 km) of travel and at every break.
. When launching a boat, do not allow
the water level to go over the exhaust
tail pipe or rear bumper.
. Make sure you disconnect the trailer
lights (if so equipped) before backing
the trailer into the water or the trailer
lights may burn out.
When towing a trailer, the transmission
fluid should be changed more fre-
quently. For additional information,
see the "9. Maintenance and schedules"
section.
TOW mode
Using TOW mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Push the TOW MODE switch to
activate tow mode. The TOW MODE
indicator light in the meter illuminates
when TOW mode is selected. Push the
TOW MODE switch again to turn TOW
mode off. TOW mode is automatically
cancelled when the ignition switch is
placed in the OFF position.
TOW mode includes the following fea-
tures:
. Grade logic — Adjusts transmission
shifts when pulling a trailer or hauling
a load up a grade. .
Downhill Speed Control (DSC) — auto-
matically downshifts when driving
down a grade with a trailer or heavy
load to help control vehicle speed.
Driving the vehicle in the TOW mode with
no trailer/load or light trailer/light load
will not cause any damage. However, fuel
economy may be reduced and the trans-
mission/engine driving characteristics
may feel unusual.
When towing a trailer, the transmission
fluid should be changed more fre-
quently. For additional information,
see the "9. Maintenance and schedules"
section.Trailer Sway Control
To minimize trailer sway, your vehicle may
apply braking to individual wheels based
on input from your vehicle sensors and
vehicle speed. Trailer Sway Control is a
function of the Vehicle Dynamic Control
(VDC) system and is active when the VDC
function is enabled.
CAUTION
If the VDC OFF switch is on (meaning
VDC system OFF), the Trailer Sway
Control is also disabled.
