has the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake* ÐCheck that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission ``P position''
mechanism ÐOn a fairly steep hill check
that your vehicle is held securely with the
selector lever in the P (Park) position with-
out applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Windshield washer fluid* ÐCheck for
adequate fluid in the tank.
Engine oil level* ÐCheck the level after
parking the vehicle on a level surface, with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and (if so equipped) clutch fluid
levels* ÐMake sure the brake and clutch
fluid level is between the MIN and MAX lines
on each reservoir.
Power steering fluid level* and lines Ð
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level* Ð
Check the level after putting the shift selec-
tor lever in P (Park) with the engine idling at
operating temperature.
Engine coolant level* ÐCheck the cool-
ant level when the engine is cold.
Radiator and hoses ÐCheck the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts* ÐMake sure the drive
belts are not frayed, worn, cracked or oily.
Battery* ÐCheck the fluid level in each
cell.
Exhaust system ÐMake sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual orthere is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
an authorized NISSAN dealer. See the car-
bon monoxide warning in the ``Starting and
driving'' section of this manual.
Underbody ÐThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, especially those areas
where mud and dirt may have accumulated.
See the ``Appearance and care'' section of
this manual.
Fluid leaks ÐCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for awhile. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately by
an authorized NISSAN dealer.

WARNING
cIt is extremely dangerous to ride in a
cargo area inside the vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
cDo not allow people to ride in any
area of the vehicle that is not
equipped with seats and seat belts.
c
Be sure everyone in the vehicle is in a
seat with their seat belt properly fas-
tened.
TERMS
It is important to familiarize yourself with the
following terms before loading your vehicle:
cCurb Weight (actual weight of your ve-
hicle) - vehicle weight including: standard
and optional equipment, fluids, emer-
gency tools, and spare tire assembly.
This weightdoes notinclude passen-
gers and cargo.
cGVW (Gross Vehicle Weight) - curb
weight plus the combined weight of pas-
sengers and cargo.
cGVWR (Gross Vehicle Weight Rating) -maximum total weight (load) limit speci-
fied for the vehicle.
cGAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified for
the front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a luggage rack, bike
carrier, cartop carrier or similar equipment
does not increase the load carrying capacity
of your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using
a commercial-grade scale, found at places
such as a truck stop, gravel quarry, grain
elevator, or a scrap metal recycling facility.
1) Determine the curb weight of your ve-
hicle.
2) Compare the curb weight amount to the
GVWR specified for your vehicle to de-
termine how much more weight your
vehicle can carry.
3) After loading (cargo and passengers),re-weigh your vehicle to determine if
either GVWR or GAWR for your vehicle
is exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
LOADING TIPS
cThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S.
Certification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
cProperly secure all cargo to help
prevent it from sliding or shifting. Do
not place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWRs. If you do,
parts of your vehicle can break, or it
can change the way your vehicle
handles. This could result in loss of
control and cause personal injury.
VEHICLE LOADING
INFORMATION

Tongue load
Keep the tongue load between 9 and 11%
of the total trailer load. If the tongue load
becomes excessive, rearrange cargo to al-
low for proper tongue load.
Maximum gross vehicle
weight/maximum gross axle weight
The gross vehicle weight of the towing
vehicle must not exceed the gross vehicle
weight rating (GVWR) shown on the
F.M.V.S.S. certification label. The gross ve-
hicle weight equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other
optional equipment. In addition, front or rear
gross axle weight must not exceed the
gross axle weight rating (GAWR) shown on
the F.M.V.S.S. certification label.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine NISSAN trailer hitch is
available from your NISSAN dealer (Canada
only). Make sure the trailer hitch is securely
attached to the vehicle to help avoid personal
injury or property damage due to sway
caused by crosswinds, rough road surfaces
or passing trucks.
CAUTION
cDo not use axle-mounted hitches.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
TI1012M
10-16Technical and consumer information
ZX

cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver's side rear door
pillar).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. Safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. Be sure to leave enough slack in the
chains to permit turning corners.
Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloadedtrailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose- down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
