CAUTION
Do not keep the starter motor engaged for more
than 10 seconds. If the engine does not start
right away, push the ignition switch to the OFF
position and wait 10 seconds before trying
again.
8. After starting your engine, carefully dis-connect the negative cable and then the
positive cable (
4→3→2→1).
9. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
10. Put the battery cover on.
Do not attempt to start the engine by pushing.
CAUTION
● Automatic transmission models cannot be
push-started or tow-started. Attempting to
do so may cause transmission damage.
● Three way catalyst equipped models should
not be started by pushing since the three
way catalyst may be damaged.
● 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 needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada).
CAUTION
● Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap or coolant reservoir
cap while the engine is still hot. When the
radiator cap or coolant reservoir cap is re-
moved, pressurized hot water will spurt out,
possibly causing serious injury.
● Do not open the hood if steam is coming out.
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:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.

3. If engine overheating is caused by climb-ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. 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 coolant is leak-
ing 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 cooling fan can start at any
time.
7. After the engine cools down, check thecoolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada). When towing your vehicle, all State (Provincial
in Canada) and local regulations for towing
must be followed. Incorrect towing equipment
could damage your vehicle. Towing instructions
are available from an INFINITI retailer. Local
service operators are familiar with the appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends that
you have a service operator tow your vehicle. It
is advisable to have the service operator care-
fully read the following precautions.WARNING
●
Never ride in a vehicle that is being towed.
● Never get under your vehicle after it has been
lifted by a tow truck.
CAUTION
● When towing, make sure that the transmis-
sion, axles, steering system and powertrain
are in working condition. If any of these con-
ditions apply, dollies or a flatbed tow truck
must be used.
● Always attach safety chains before towing.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when the
engine is cold. If the coolant level is below MIN
2, open the reservoir tank cap and add coolant
up to the MAX
1level. If the reservoir tank is
empty, check the coolant level in the radiator
when the engine is cold. If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add it
to the reservoir tank up to the MAX level
1.
Tighten the cap securely after adding engine
coolant. This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue). The life expectancy of
the factory-fill coolant is 105,000 miles
(168,000 km) or 7 years. Mixing any other type
of coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the INFINITI Service and Main-
tenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●
To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap or coolant res-
ervoir cap when the engine is hot. Serious
burns could be caused by high pressure fluid
escaping from the radiator. ●
Avoid direct skin contact with used coolant.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep coolant out of reach of children and
pets.
Engine coolant must be disposed of properly.
Check your local regulations.

E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.
Technical and consumer information9-5

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-
fect engine performance and cause overheat-
ing. The transmission high fluid temperature
and engine protection mode, which helps re-
duce the chance of transmission and engine
damage, could activate and automatically de-
crease engine power. Vehicle speed may de-
crease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be especially
careful when driving. If the vehicle cannot
maintain a safe driving speed, pull to the side
of the road in a safe area. Allow the engine to
cool and return to normal operation. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
CAUTION
Vehicle damage resulting from improper tow-
ing procedures is not covered by INFINITI
warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 to 15% of the total trailer load or use
the trailer tongue load specified by the trailer
manufacturer. The tongue load must be within
the maximum tongue load limits shown in the
following “Towing Load/Specification” chart. If
the tongue load becomes excessive, rearrange
cargo to allow for proper tongue load.

9-18Technical and consumer information

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 selector lever to the P
(Park) position before blocking the wheels and
applying the parking brake, transmission dam-
age could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the down-hill 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 Transmission (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 and trailer
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 de-
crease overall stability. Therefore, to main-
tain 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” in the “6. In case of emer-
gency” section.
● Trailer towing requires more fuel than nor-
mal 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 in the INFINITI Service
and Maintenance Guide.
● 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 adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle 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 combination will help stabilize
the vehicle.
– Do not correct trailer sway by steering orapplying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road
in a safe area.
