8-4Maintenance and do-it-yourself
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.
Brake pedal: Check the pedal for smooth
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 seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel:
Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
Brake fluid level*:
Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) section for exhaust gas (carbon
monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or

HEADLIGHTS
Replacing
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
contact an INFINITI retailer.
Xenon headlight bulb (if so equipped):
If replacement is required, see an INFINITI
retailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced at an INFINITI retailer. For addi-
tional information, see “Headlight and turn
signal switch” (P.2-36).

to the hitch, not to the vehicle bumper or
axle. The safety chains can be attached to
the bumper if the hitch ball is mounted to
the bumper. Be sure to leave enough slack
in the chains to permit turning corners.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more than
15 milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.
See a reputable trailer retailer to obtain
the proper equipment and to have it
installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in hooking up trailer lights, contact an
INFINITI retailer or reputable trailer retailer.
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
properly installed.
WARNING
Never connect a trailer brake system directly
to the vehicle brake system.
Pre-towing tips
.
Be certain your vehicle maintains a level
position when a loaded or unloaded
trailer 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 possible causes of
either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center of
gravity low. .
Load the trailer so approximately 60%
of the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every
time you attach a trailer to the vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
clearance is known.Trailer towing tips
In order to gain skill and an understanding
of the vehicle’ s behavior, you should
practice turning, stopping and backing up
in an area which is free from traffic.
Steering stability, and braking perfor-
mance will be somewhat different than
under normal driving conditions.
. Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a pin
or lock to prevent the coupler from
