6. Af ter the engine cools down, check thecoolant level in the engine coolant res-
ervoir with the engine running. Add
coolant to the engine coolant reservoir
if necessary. Have your vehicle re-
paired. It is recommended that you visit
a NISSAN dealer for this service. When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from a
NISSAN dealer. Local service operators are
generally familiar with the applicable laws
and procedures for towing. To assure
proper towing and to prevent accidental
damage to your vehicle, NISSAN recom-
mends having a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions:
WARNING
∙ Never ride in a vehicle that is being
towed.
∙ Never get under your vehicle af ter it has been lif ted by a tow truck.
CAUTION
∙ When towing, make sure that thetransmission, axles, steering system
and powertrain are in working condi-
tion. If any of these conditions apply,
dollies or a flatbed tow truck must be
used.
∙ Always attach safety chains before towing.
For additional information, refer to “Flat
towing” in the “Technical and consumer in-
formation” section of this manual.
TOWING RECOMMENDED BY
NISSAN
NISSAN recommends towing your vehicle
based upon the type of drivetrain. For addi-
tional information, refer to the diagrams in
this section to ensure that your vehicle is
properly towed.
TOWING YOUR VEHICLE
6-12In case of emergency

2WD 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 CVT models with the frontwheels on the ground or four wheels
on the ground (forward or backward),
as this may cause serious and expen-
sive damage to the transmission. If it
is necessary to tow the vehicle with
the rear wheels raised always use
towing dollies under the front wheels.
∙ When towing 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).
LCE2345
In case of emergency6-13

2WD models with manual
transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on the flatbed truck as illus-
trated.
If you must use a pull behind tow truck put
the manual transmission in N (Neutral).
Your vehicle speed should never exceed
60 mph (97 km/h) when towing your ve-
hicle. Af ter towing 500 miles, start and idle
the engine with the transmission in N (Neu-
tral) for two minutes. Failure to idle the en-gine af ter every 500 miles of towing may
cause damage to the transmission’s inter-
nal parts.
CAUTION
Failure to follow these guidelines can
result in severe transmission damage.
∙ If you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the ground:
– Always release the parking brake. – Move the transmission shif t lever
to the N (Neutral) position
– Observe the following restricted towing speeds and distances for
manual transmission models only:
Speed: Below 60 mph (97 km/h)
Distance: Less than 500 miles
(805 km)
When towing long distances or speeds in
excess of 60 mph (97 km/h), remove the
propeller shaf t before towing to prevent
damage to the transmission. For additional
information, it is recommended that you
visit a NISSAN dealer.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious per-
sonal injury or death when recovering a
stuck vehicle:
∙ Contact a professional towing service to recover the vehicle if you have any
questions regarding the recovery
procedure.
LCE2346
6-14In case of emergency

∙ Tow chains or cables must be at-tached only to main structural mem-
bers of the vehicle.
∙ Do not use the vehicle tie-downs to tow or free a stuck vehicle.
∙ Only use devices specifically designed for vehicle recovery and follow the
manufacturer’s instructions.
∙ Always pull the recovery device straight out from the front of the ve-
hicle. Never pull at an angle.
∙ Route recovery devices so they do not touch any part of the vehicle except
the attachment point.
If your vehicle is stuck in sand, snow, mud,

Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle.
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 (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and
with the parking break fully applied, po-
sition the floor mat in the floorwell so
that the floor mat grommet holes are
aligned with the hook(s).
2. Secure the grommet holes into the hook(s) 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 (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and
with the parking break applied, fully ap-
ply 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.

∙ NISSAN recommends using Genuine NISSAN CVT Fluid NS-3 (or equivalent)
ONLY in NISSAN CVTs. Do not mix with
other fluids.
∙ Do not use Automatic Transmission Fluid (ATF) or manual transmission
fluid in a NISSAN CVT, as it may dam-
age the CVT. Damage caused by the
use of fluids other than as recom-
mended is not covered under
NISSAN’s New Vehicle Limited
Warranty.
∙ Using fluids that are not equivalent to Genuine NISSAN CVT Fluid NS-3 may
also damage the CVT. Damage caused
by the use of fluids other than as rec-
ommended is not covered under

∙ Always use tires of the same type,size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) system
to malfunction resulting in personal
injury or death, excessive tire wear
and may damage the transmission
and differential gears.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S on the tire sidewall.
Snow tires have better snow traction than
All Season tires and may be more appropri-
ate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels. For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 205/50R17 and 215/45ZR18
size tires. Installation of the tire
chains/cables on 205/50R17 and
215/45ZR18 size tires will cause damage
to the vehicle. If you plan to use tire
chains/cables, you should install
205/55R16 size tires on your vehicle.
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer’s suggestions. Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
