CAUTION
• Do not push start this vehicle. The
three-way catalyst may be
damaged.
• Continuously Variable Transmission
(CVT) models and Manual Transmis-
sion (M/T) cannot be push-started or
tow-started. Attempting to do so
may cause transmission damage.
• For Manual Transmission (M/T) mod-
els, never try to start the vehicle by
towing it. When the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle. 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 ve-
hicle 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 radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
• Do not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the shif t
lever to N (Neutral) (manual transmis-
sion) or to P (Park) (CVT).
Do not stop the engine.
2. Turn off the air conditioner (if so equipped). Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.

6. Af ter the engine cools down, check thecoolant level in the engine coolant res-
ervoir with the engine running. Add cool-
ant to the engine coolant reservoir if
necessary. Have your vehicle repaired. 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 the
transmission, 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

CAUTION
• Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
• Use electrical accessories with the
engine running to avoid discharging
the vehicle battery. Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
The current sensor
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.

WARNING
• Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in
the tread. If excessive wear,
cracks, bulging or deep cuts
are found, the tire(s) should be
replaced.
• The original tires have built-in
tread wear indicators. When
the wear indicators are visible,
the tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, including the
spare, over 6 years old checked
by a qualified technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” in the “Technical and con-
sumer information” section of this manual.
WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could re-
sult in serious personal injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four 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
conditions and cause an accident
and personal injury.
