engine overheat NISSAN SENTRA 2009 Owner´s Manual

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outside
temperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally decrease engine power. Vehicle speed may
decrease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. See “If your
vehicle overheats” in the “In case of emer-
gency” section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
NISSAN warranties.
Tongue load
Keep the tongue load between 10 - 15 percent of
the total trailer load or use the trailer tongue load
specified by the trailer manufacturer. The tongue
load must be within the maximum tongue load
limits shown in the following “Towing
Load/Specification” chart. If the tongue load be-
comes 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.

●Always drive your vehicle at a moderate
speed.
●When 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. 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.
●While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as fre-
quently.
●If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
●Trailer towing requires more fuel than normal
circumstances.●Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
●For the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
●Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
●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.
●Crosswinds 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 combination will help stabilize the ve-
hicle.
– 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.
●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.
●Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
●Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
●Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
●NISSAN recommends that the cruise con-
trol not be used while towing a trailer.●Some states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
●Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
●When launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
●Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, transmission fluid
should be changed more frequently. For
additional information, see the “Mainte-
nance and do-it-yourself” section earlier in
this manual.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
●Failure to follow these guidelines can
result in severe transmission damage.
●Whenever flat towing your vehicle, al-
ways tow forward, never backward.
●DO NOT tow any continuously variable
transmission vehicle with all four
wheels on the ground (flat towing) . Do-
ing so WILL DAMAGE internal transmis-
sion parts due to lack of transmission
lubrication.
●For emergency towing procedures refer
to “Towing recommended by NISSAN”
in the “In case of emergency” section of
this manual.
Continuously Variable Transmission
To tow a vehicle equipped with a continuously
variable transmission, an appropriate vehicle dolly
MUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
