2008 NISSAN FRONTIER Owners Manual

Tongue load
When using a weight carrying or a weight distrib-
uting hitch, keep the tongue load between 10 -
15 percent of the total trailer load within the
maximum tongue load limits shown in the follow-
ing “Towing Load/Specification” chart. If the
tongue load becomes excessive, rearrange cargo
to allow for proper tongue load.
Maximum Gross Vehicle Weight
(GVW)/maximum Gross Axle Weight
(GAW)
The GVW of the towing vehicle must not exceed
the Gross Vehicle Weight Rating (GVWR)
shown on the F.M.V.S.S./C.M.V.S.S. certification
label. The GVW equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other optional
equipment. In addition, front or rear GAW must
not exceed the Gross Axle Weight Rating
(GAWR) shown on the F.M.V.S.S./C.M.V.S.S.
certification label.Towing capacities are calculated assuming a
base vehicle with driver and any options required
to achieve the rating. Additional passengers,
cargo and/or optional equipment, such as the
trailer hitch, will add weight to the vehicle and
reduce your vehicle’s maximum towing capacity
and trailer tongue load.
The vehicle and trailer need to be weighed to
confirm the vehicle is within the GVWR, Front
GAWR, Rear GAWR, Gross Combined Weight
Rating (GCWR) and Towing capacity.
All vehicle and trailer weights can be measured
using platform type scales commonly found at
truck stops, highway weigh stations, building
supply centers or salvage yards.
To determine the available payload capacity for
tongue load, use the following procedure.
1. Locate the GVWR on the
F.M.V.S.S./C.M.V.S.S. certification label.
2. Weigh your vehicle on the scale with all of
the passengers and cargo that are normally
in the vehicle when towing a trailer.
3. Subtract the actual vehicle weight from the
GVWR. The remaining amount is the avail-
able maximum tongue load.

To determine the available towing capacity, use
the following procedure.
1. Find the GCWR for your vehicle on the
9Towing Load/Specification9chart found
later in this section.
2. Subtract the actual vehicle weight from the
GCWR. The remaining amount is the avail-
able maximum towing capacity.
To determine the Gross Trailer Weight, weigh
your trailer on a scale with all equipment and
cargo, that are normally in the trailer when it is
towed. Make sure the Gross Trailer Weight is not
more than the Gross Trailer Weight Rating shown
on the trailer and is not more than the calculated
available maximum towing capacity.
Also weigh the front and rear axles on the scale to
make sure the Front Gross Axle Weight and Rear
Gross Axle Weight are not more than Front
Gross Axle Weight and Rear Gross Axle Weight
on the F.M.V.S.S./C.M.V.S.S. certification label.
The cargo in the trailer and vehicle may need to
be moved or removed to meet the specified rat-
ings.
Example:
cGross Vehicle Weight (GVW) as weighed
on a scale- including passengers, cargo and
hitch - 5,185 lb. (2352 kg) .cGross Vehicle Weight Rating (GVWR) from
F.M.V.S.S./C.M.V.S.S. certification label -
5,815 lb. (2638 kg) .
cGross Combined Weight Rating (GCWR)
from “Towing Load/Specification9chart -
11,133 lb. (5050 kg) .
cMaximum Trailer towing capacity from “Tow-
ing Load/Specification9chart - 6,100 lb.
(2767 kg) .
5,815 lb. (2638 kg) GVWR
– 5,185 lb. (2352 kg) GVW
= 630 lb. (286 kg) Available for tongue
weight
11,133 lb. (5050 kg) GCWR
– 5,185 lb. (2352 kg) GVW
= 5,948 lb. (2698 kg) Capacity available for
towing
630 lb. (286 kg) Available tongue weight
/ 5,948 lb. (2698 kg) Available capacity
= 10 % tongue weight
The available towing capacity may be less than
the maximum towing capacity due to the passen-
ger and cargo load in the vehicle.
Remember to keep trailer tongue weight be-
tween 10 - 15% of the trailer weight. If the tongue
load becomes excessive, rearrange the cargo toobtain the proper tongue load. Do not exceed the
10 - 15% tongue weight specification even if the
calculated available tongue weight is greater
than 15%. If the calculated tongue weight is less
than 10% , reduce the total trailer weight to
match the available tongue weight.
Always verify that available capacities are within
the required ratings.
Trailer frontal area
CAUTION
Exceeding the maximum trailer frontal
area specification may exceed the towing
capacity of the vehicle. This may affect the
towing performance and lead to vehicle
damage.
The trailer frontal area affects the towing load of a
trailer. The frontal area is the total area of the
vehicle and trailer that is affected by air resis-
tance while towing. Do not exceed the maximum
trailer frontal area specification shown in the
9Towing Load/Specification” chart. The frontal
area can be determined by multiplying the width
of the trailer by the height of the trailer. For
example, a trailer that is 8 feet wide by 6 feet tall
has a trailer frontal area of 48 square feet.

TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an optional
trailer tow package. The trailer tow package in-
cludes a receiver-type frame mounted hitch. This
hitch is rated for the maximum towing capacity of
this vehicle when the proper towing equipment is
used. Choose a proper ball mount and hitch ball
that is rated for the trailer to be towed. Genuine
Nissan ball mounts and hitch balls are available
from your NISSAN dealer.If your vehicle is not equipped with the optional
trailer tow package, check the towing capacity of
your bumper hitch or receiver-type frame
mounted hitch. Choose a proper hitch for your
vehicle and trailer. A genuine Nissan trailer hitch
is available from your NISSAN dealer. 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.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than the
weight rating of the hitch components.
Never exceed the weight rating of the
hitch components. Doing so can cause
serious personal injury or property
damage.

Hitch ball
Choose a hitch ball of the proper size and weight
rating for your trailer:
cThe required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on the top of the ball.
cChoose the proper class hitch ball based on
the trailer weight.
cThe diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should
be no more than 1/16” smaller than the hole
in the ball mount.
cThe threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount and
the ball mount is inserted into the hitch receiver.
Choose a proper class ball mount based on the
trailer weight. Additionally, the ball mount should
be chosen to keep the trailer tongue level with the
ground.
Bumper towing
The genuine NISSAN step bumper has provi-
sions to install a trailer hitch ball and is designed
to tow trailers of a maximum weight of 3,500 lb
(1,588 kg) .
To install a trailer hitch ball cut out the circle in the
center of the step bumper
sA, then remove it to
install the trailer hitch ball.
Weight carrying hitches
A weight carrying or9dead weight9ball mount is
one that is designed to carry the whole amount of
tongue weight and gross weight directly on the
ball mount and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling” or
“equalizing” hitch. A set of bars attach to the ball
mount and to the trailer to distribute the tongue
weight (hitch weight) of your trailer. Many ve-
hicles can’t carry the full tongue weight of a given
trailer, and need some of the tongue weight
transferred through the frame and pushing down
on the front wheels. This gives stability to the tow
vehicle.
Another reason to have a weight distributing ball
mount is to comply with the rating on your re-
ceiver. Most receivers have a weight carrying
rating of 5,000 lbs. gross weight, 500 lbs. tongue
weight and a weight distribution rating of 10,000
lbs. gross weight, 1,000 lbs. tongue weight. This
means that without using a weight distributing
ballmount, the receiver is only designed to carry
5,000 lbs.
When hooking up a trailer using a weight distrib-
uting hitch, always refer to the hitch manufactur-
er’s instructions.
1. Park unloaded vehicle on a level surface.
With the ignition on and the doors closed,
allow the vehicle to stand for several minutes
so that it can level.

2. Measure the height of a reference point on
the front and rear bumpers at the center of
the vehicle.
3. Attach the trailer to the vehicle and adjust
the hitch equalizers so that the front bumper
height is within0-.5inches (0 – 13 mm) of
the reference height measured in step 2. The
rear bumper should be no higher than the
reference height measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If the
rear bumper is higher than the measured
reference height when loaded, the vehicle
may handle unpredictably which could
cause a loss of vehicle control and cause
serious personal injury or property
damage.
Sway control device
Sudden maneuvers, wind gusts, and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to make
sure the sway control device will work with the
vehicle, hitch, trailer and the trailer’s brake sys-tem. Follow the instructions provided by the
manufacturer for installing and using the sway
control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb (909 kg) .
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 3,500 lb (1,510 kg) .
The genuine NISSAN step bumper is considered
a Class II ball mount.
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 5,000 lb (2,272 kg) .
Class IV hitch
Class IV trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 10,000 lb (4,545 kg) . A
weight distributing hitch should be used to tow
trailers that weigh over 5,000 lb (2,272 kg) .
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000 lb(4,545 kg) maximum weight rating, but your ve-
hicle is only capable of towing the maximum
trailer weights shown in the “Towing
Load/Specification” chart earlier in this section.
CAUTION
cSpecial hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches, ball mounts and
hitch balls for pickup trucks and sport
utility vehicles are available at a
NISSAN dealer.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.
cTo reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
cRegularly check that all trailer hitch
mounting bolts are securely mounted.

cWhen towing with the hitch ball
mounted to the rear bumper, do not
make sharp turns. The trailer may con-
tact the bumper and cause damage to
the bumper or trailer.
Tire pressures
cWhen towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
cTrailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. The safety chains should
be crossed and should be attached 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
that 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 dealer 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 a NISSAN dealer or repu-
table trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped with a
7-pin trailer harness connector. A flat 4–pin har-
ness is available from your dealer for vehicles
without a tow package. If your trailer is equipped
with a flat 4-pin connector, an adapter will beneeded to connect the trailer lights to the vehicle.
Adapters are available at auto parts stores and
hitch retailers.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.
Vehicles equipped with a 7–pin trailer harness
connector are pre-wired for a trailer brake con-
troller. See a NISSAN dealer for a trailer brake
adapter harness.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
Electric trailer brake controller
Trailers equipped with electric brakes may re-
quire the installation of an aftermarket trailer
brake controller.
A Genuine NISSAN jumper harness is available
that is specifically designed to be used when
installing an aftermarket brake controller.
Install the aftermarket electric trailer brake con-
troller according to the manufacturer’s instruc-
tions.

Pre-towing tips
cBe 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 possible
causes of either condition.
cAlways secure items in the trailer to prevent
load shift while driving.
c
Keep the cargo load as low as possible in the
trailer to keep the trailer center of gravity low.
cLoad 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.
cCheck your hitch, trailer tire pressure, ve-
hicle tire pressure, trailer light operation, and
trailer wheel lug nuts every time you attach a
trailer to the vehicle.
cBe certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
cDetermine 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.
cAlways secure items in the trailer to prevent
load shift while driving.
cLock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadvert-
ently becoming unlatched.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cWhen backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill
side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly
release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Make sure the
indicator light (if so
equipped) indicates the transfer case is in
4H, 4L, or 2H and that the ATP light is off. If
the
indicator light is flashing, or the
ATP light is ON, make sure the transmission
is in P (Park) (AT) and turn the 4WD switch
to 2WD or 4H. See9Automatic transmission
park warning light9in the9Instruments and
controls9section and9Using four wheel
drive9in the9Starting and driving9section.
7. Turn off the engine.

To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
c
When going down a hill, shift into a lower gear
and use the engine braking effect. When go-
ing up a long grade, downshift the transmis-
sion to a lower gear and reduce speed to
reduce chances of engine overloading and/or
overheating. However, for long steep grades,
do not stay in 1st gear when driving above 35
MPH (56 km/h) or 2nd gear when driving
above 58 MPH (93 km/h) .
cIf the engine coolant rises to an extremely
high temperature when the air conditioner
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.cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cFor the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
cHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
cWhen 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.
cCrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway:
1.
Take your foot off the accelerator pedal to
allow the vehicle to coast and steer as straight
ahead as the road conditions allow. This com-
bination will help stabilize the vehicle
– Do not correct trailer sway by steering or
applying the brakes.
2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal-
anced as described earlier in this section.
cBe 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.
cDownshift the transmission to a lower gear
for engine braking when driving down steep
or long hills. This will help slow the vehicle
without applying the brakes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
overdrive.
cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
cIncrease your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
