“Wheels and tires” in the “Do-it-yourself ”
section of this manual.1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (

WARNING
∙ Always make sure that the spare tireand jacking equipment are properly
secured af ter use. Such items can be-
come dangerous projectiles in an ac-
cident or sudden stop.
∙ The spare tire is designed for emer- gency use. For additional information,
refer to “Wheels and tires” in the “Do-
it-yourself ” section of this manual. To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
∙ If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
∙ Explosive hydrogen gas is always present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
∙ Do not allow battery fluid to come into contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
∙ Keep battery out of the reach of children.
∙ The booster battery must be rated at 12 volts. Use of an improperly rated
battery can damage your vehicle. ∙ Whenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the battery
when jump starting.

Two-Wheel Drive models with
Continuously Variable
Transmission (CVT)
NISSAN recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed
truck as illustrated.
CAUTION
∙ Never tow Continuously VariableTransmission (CVT) models with the
front wheels on the ground or four
wheels on the ground (forward or
backward), as this may cause serious
and expensive damage to the trans-
mission. If it is necessary to tow the
vehicle with the rear wheels raised
always use towing dollies under the
front wheels. ∙ When towing Continuously Variable
Transmission (CVT) models with the
rear wheels on the ground or on tow-
ing dollies:
– Place the ignition switch in the OFF position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by plac-
ing the ignition switch in the LOCK
position. This may damage the
steering lock mechanism (for
models with a steering lock
mechanism).

FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference
that may result in a collision, injury or
death:
∙ NEVER place a floor mat on top ofanother floor mat in the driver front
position or install them upside down
or backwards. ∙ Use only Genuine NISSAN floor mats,
or equivalent floor mats, that are
specifically designed for use in your
vehicle model and model year.
∙ Properly position the mats in the floorwell using the floor mat position-
ing aid. For additional information, re-
fer to "Floor mat installation" in this
section.
∙ Make sure the floor mat does not in- terfere with pedal operation.
∙ Periodically check the floor mats to make sure they are properly installed.
∙ Af ter cleaning the vehicle interior, check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning aids. The number and shape of the floor mat positioning aid for each seat-
ing position varies depending on the ve-
hicle.
When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the shif t lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the positioning aids.
2. Secure the grommet holes into the po- sitioning aids and ensure that the floor
mat is properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t
lever in the P (Park) position and with
the parking brake applied, fully apply
and release all pedals. The floor mat
must not interfere with pedal opera-
tion or prevent the pedal from return-
ing to its normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle.
