Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch in a fully open position. If the hood,
trunk, or rear hatch is not held open, have the
gas stays or struts replaced.
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 checking
the tires, make sure no wheel nuts are miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule. Tires*:
Check the pressure with a gauge of-
ten and always prior to long distance trips. If
necessary, adjust the pressure in all tires, in-
cluding 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.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet. 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. It is recommended that you have
a damaged windshield repaired by an INFINITI
retailer, or an INFINITI Certified Collision Cen-
ter. To locate a collision center in your area,
refer to http://collision.infinitiusa.com.
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 scheduled 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.
Brake pedal: Check the pedal for smooth op-
eration. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended that you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Maintenance and schedules9-3

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 us-
ing the vehicle tail light, stop light 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 sys-
tem. See a reputable trailer retailer to ob-
tain 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. Vehicles
equipped with the optional trailer tow pack-
age are equipped with a 7-pin trailer harness connector. If your trailer is equipped with a
flat 4-pin connector, an adapter will be
needed to connect the trailer lights to the
vehicle. Adapters are available at auto parts
stores and hitch retailers.Trailer brakes
Most states require a separate braking sys-
tem on trailers with a loaded weight above a
specific amount, make sure the trailer meets
the local regulations and the regulations
where you plan to tow.
Several types of braking systems are
available.
Surge Brakes -
The surge brake actuator is
mounted on the trailer tongue with a hydrau-
lic line running to each trailer wheel. Surge
brakes are activated by the trailer pushing
against the hitch ball when the tow vehicle is
braking. Hydraulic surge brakes are common
on rental trailers and some boat trailers. In
this type of system, there is no hydraulic or
electric connection for brake operation be-
tween the tow vehicle and the trailer.
Electric Trailer Brakes - Electric braking sys-
tems are activated by an electronic signal
sent from a trailer brake controller (special
brake-sensing module). Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
Pre-towing tips
• Be certain your vehicle maintains a level position when a loaded and/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 pos-
sible 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 grav-
ity 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.
