overheating NISSAN QUEST 2014 RE52 / 4.G Owners Manual

WARNING
.If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
. When the hydraulic pump electric
power steering warning light illumi-
nates with the engine running, the
power assist for the steering will
cease operation. You will still have
control of the vehicle, but the steer-
ing will be much harder to operate.
The hydraulic pump electric power steering
system is designed to provide power assistance
while driving to operate the steering wheel with
light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent
overheating of the hydraulic pump electric
power steering system and protect it from
getting damaged. While the power assist is
reduced, steering wheel operation will become
heavy. If the steering wheel operation is still
performed, the power steering may stop and the hydraulic pump electric power steering warning
light will illuminate. Stop the engine and push
the ignition switch to the OFF position. The
temperature of the hydraulic pump electric
power steering system will go down and the
power assist level will return to normal after
starting the engine. The hydraulic pump electric
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the hydraulic pump electric power
steering system to overheat.
You may hear a noise from the front of the
vehicle when the steering wheel is operated.
This is not a malfunction.
If the hydraulic pump electric power steering
warning light illuminates while the engine is
running, it may indicate the hydraulic pump
electric power steering system is not functioning
properly and may need servicing. Have the
hydraulic pump electric power steering system
checked by a NISSAN dealer.
When the hydraulic pump electric power steer-
ing warning light illuminates with the engine
running, the power assist for the steering will
cease operation but you will still have control of
the vehicle. At this time, greater steering efforts
are required to operate the steering wheel,
especially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.

the engine of the vehicle
*Abeing jump
started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, place the
ignition switch in the OFF position and
wait 10 seconds before trying again.
7. After starting your engine, carefully discon- nect the negative cable and then the positive
cable (
*4?*3?*2?*1).
8. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid. Do not attempt to start the engine by pushing.
CAUTION
Continuously Variable Transmission
(CVT) models cannot be push-started
or tow-started. Attempting to do so may
cause transmission damage.
CAUTION
.
Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.
PUSH STARTING IF YOUR VEHICLE OVERHEATS

9-4Technical and consumer information
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in NISSAN
vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are experienced
after using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-
15 fuel. Do not use E-15 in your vehicle. U.S.
government regulations require fuel ethanol
dispensing pumps to be identified with small,
square, orange and black label with the common
abbreviation or the appropriate percentage for
that region.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage for
that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock”. (Spark
knock is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark knock
even when using gasoline of the stated
octane rating, or if you hear steady spark knock while holding a steady speed on
level roads, have a NISSAN dealer correct
the condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are
encountered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

9-16Technical and consumer information
guide includes information on trailer towing
capability and the special equipment required
for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the “Towing Load/Specifica-
tion” chart. The total trailer load equals trailer
weight plus its cargo weight.
.When towing a trailer load of 1,000 lbs
(454 kg) or more, trailers with a brake
system MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following “Towing Load/Specification” chart.
STI0541
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greater
than these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but
also the places you plan to tow. Tow weights
appropriate for level highway driving may have to
be reduced on very steep grades or for low
traction situations (for example, on slippery boat
ramps) .
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 overheat-
ing. The transmission high fluid temperature
protection mode, which helps reduce the
chance of transmission damage, could activate
and automatically 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 en-
gine power and vehicle speed. The
reduced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving 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” (P.6-12) of this manual.
CAUTION
Vehicle damage resulting from impro-
per towing procedures are not covered

9-22Technical and consumer information
.Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
. Be certain your rearview mirrors conform 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
performance 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 inadver-
tently becoming unlatched.
. Avoid abrupt starts, acceleration or stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moderate
speed. Some states or provinces have
specific speed limits for vehicles that are towing trailers. Obey the local speed limits.
. 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 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
absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) . 6. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
2. Start the engine.
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.
. When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating.
. 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.
. Trailer towing requires more fuel than normal
circumstances.
. Avoid towing a trailer for the first 500 miles
(800 km) .
