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. Refer to specific instruc-
tions under the heading “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.
∙ Do not attempt to jump start a frozen battery. It could explode and cause
serious injury.
∙ Your vehicle has an automatic engine cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
JUMP STARTING
In case of emergency6-9

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to
touch. 2. Apply the parking brake. Move the shif t
lever to N (Neutral) (manual transmis-
sion) or to P (Park) (CVT). Switch off all
unnecessary electrical systems (lights,
heater, air conditioner (if so equipped),
etc.).
3. Turn the ignition switch to the LOCK position.
4. Ensure the vent caps are level and tight.
5. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to posi-tive ( ) and negative () to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to
the battery.
∙ Make sure the jumper cables do not touch moving parts in the engine
compartment and that the cable
clamps do not contact any other
metal.
6. Start the engine of the booster vehicle and let it run for a few minutes.
7. Keep the engine speed of the booster vehicle at about 2,000 rpm and start the
engine of the vehicle being jump
started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, place the ig-
nition switch in the OFF position and
wait 3 to 4 seconds before trying again.
8. Af ter starting the engine, carefully dis- connect the negative cable and then
the positive cable.

6-10In case of emergency

CAUTION
∙ Do not push start this vehicle. Thethree-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 vehicle
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 vehicle
overheats. Doing so could cause en-
gine 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 com- ing out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to N (Neutral) (manual trans-
mission) 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
radiator 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
radiator should not leak water. If cool-
ant 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 contact
with, or get caught in, engine belts or
the engine cooling fan. The engine cool-
ing 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
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

Two-Wheel Drive 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.
