condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
O Always secure items in the trailer to prevent
load shifts while driving.
O Be certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
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 performance will be somewhat differ-
ent than under normal driving conditions.
O Always secure items in the trailer to prevent
load shift while driving.
O Avoid abrupt starts, acceleration or stops.
O Avoid sharp turns or lane changes.
O Always drive your vehicle at a moderate
speed.
O Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so, and if your vehicle is equipped with automatic transmission, first apply the
parking brake and block the wheels, and
then move the transmission selector lever
into the P (Park) position. If you move the
selector lever to the P (Park) position be-
fore blocking the wheels and applying the
parking brake, the transmission may be
damaged.
O When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending on a long grade, down-
shift the transmission to a lower gear and
reduce speed to reduce chances of engine
overloading and/or overheating.
O If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
O Trailer towing consumes more fuel than
normal circumstances.
O Avoid towing a trailer for the first 500 miles
(800 km).
O Have your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule. O 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.
O 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
vehicle handling. If swaying does occur,
firmly grip the steering wheel, steer straight
ahead, and immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
O Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer
must also pass the other vehicle before you
can safely change lanes.
O To maintain engine braking efficiency and
electrical charging performance, do not use
sixth gear (manual transmission) or fifth
position (automatic transmission).
O Avoid holding the brake pedal down too
long or too frequently such as on long
down-hill sections of road. This could cause

the brakes to overheat, resulting in reduced
braking efficiency. Shift down and use en-
gine braking.
When towing a trailer, change transmission
oil more frequently.
See ªPeriodic maintenance schedulesº in
the ª9. Maintenanceº section. Shift down
and use engine braking. DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform
to federal safety requirements in addition to
these grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
WARNING The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.UNIFORM TIRE QUALITY

IN THE EVENT OF A COLLISION Unfortunately, accidents do occur. In this un-
likely event, there is some important informa-
tion you should know. Many insurance compa-
nies routinely authorize the use of non-
genuine collision parts in order to cut costs,
among other reasons.
Insist on the use of Genuine Infiniti
Collision Parts! If you want your vehicle to be restored using parts made to INFINITI's original exacting
specifications Ð if you want to help it to last
and hold its resale value, the solution is
simple. Tell your insurance agent and your
repair shop to only use Genuine Infiniti
Collision Parts. INFINITI does not warrant
non-Infiniti parts, nor does Infiniti's warranty
apply to damage caused by a non-genuine
parts.
Using Genuine Infiniti Parts can help protect
your personal safety, preserve your warranty
protection and maintain the resale value of
your vehicle. And if your vehicle was leased,
using Genuine Infiniti Parts may prevent or
limit unnecessary excess wear and tear ex-
penses at the end of your lease.
INFINITI designs its hoods with crumple zones
to minimize the risk that the hood will penetrate
the windshield of your vehicle in an accident.
Non-genuine (imitation) parts may not provide
such built in safety features. Also, non-genuine
parts often show premature wear, rust and
corrosion.
Why should you take a chance? In over 40 states, the law says you must be
advised if non-genuine parts are used to repair
your vehicle. And some states/provinces have
enacted laws that restrict insurance compa-
nies from authorizing the use of non-genuineOWNER'S MANUAL/SERVICE
