contaminated with corrosive acid.
9. 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. Attempt-
ing 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.
CAUTION
.Do not continue to drive if your vehicle
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 radiator cap
is removed, 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
conditioner temperature control to
maximum hot and fan control to high

TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
. Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious and expensive damage to the transmis-
sion. If it is necessary to tow the vehicle
with the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Push the ignition
switch to the ACC or ON position, and
secure the steering wheel in a straight-
ahead position with a rope or similar
device.

When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated
every 7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to
wear or age.
Tire, wheel alignment and balance: If thevehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to
“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Windshield: Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism:
On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.

operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as

those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see“Cleaning exterior” in the“7. Appear-
ance and care ”section.
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.

CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. In-
dividual axle loads should not
exceed either of the gross axle
weight ratings (GAWR). The total of
the axle loads should not exceed the
gross vehicle weight rating (GVWR).
These ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings.Do not tow a trailer with your
vehicle.FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational
vehicle, such as a motor home.
CAUTION
.
Failure to follow these guidelines can
result in severe transmission damage.
. Whenever flat towing your vehicle, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
. DO NOT tow an All-Wheel Drive (AWD)
vehicle with any of the wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
. For emergency towing procedures refer
to“Towing recommended by INFINITI” in
the “6. In case of emergency” section ofthis manual.
Automatic transmission
All-Wheel Drive (AWD) models:
Do not tow an AWD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an auto-
matic transmission, an appropriate vehicle
dolly
MUST be placed under the towed
vehicle’s drive wheels. Alwaysfollow the
dolly manufacturer’ s recommendations
when using their product.
