WARNING- Do not use or rely upon the Back-up Collision Intervention system (BCI)
when towing a trailer. The BCI system cannot function properly when objects are
obstructing the radar sensor beams.

PARK SMART

A tow vehicle and trailer can be an unwieldy combination in a sma ll area, so always
try to park where you will have a relatively easy time maneuvering. Once parked,
always block the wheels on both the tow vehicle and the trailer.

Parking on a slope is not recommended. If, however, you must park on a slope and
since y our vehicle is equipped with an automatic transmission, there are some
precautions you should take:
 Turn the wheels of the tow vehicle towards the side of the road away from the
center of the road, and apply the parking brake and only then move the gear lever
into PARK.
 Next, block /chock the wheels once the tow vehicle and trailer are in position and
are being held by the vehicle’s brake.

CAUTION- If you move the lever into PARK before blocking the wheels and applying
the parking brake, it may be difficult to later shift out of PARK. Transmission damage
may also occur.

PASS CAREFULLY
As mentioned in the introduction to this section, because of the added weight of the
trailer, acceleration capability is reduced and you will require a longer distance to
pass another vehicle. Be certain you have sufficient time and space to pass safely.


WARNING - Never attempt to pass on hills or when going around curves. Doing so
could cause a loss of vehicle control and result in accident , property damage or
personal injury. Because the trailer does not follow the exact path as the tow vehicle
on turns, safely passing and cornering while towing takes considerably more distance
and turning space than normal. Be certain you have sufficient time and space to pass
safely , remember, the length of the trailer must also pass the other vehicle before you
can safely change lanes.

HILLS – UPGRADES
Your vehicle was designed to be used primarily to carry passengers and cargo. If your
Infiniti
vehicle owner’s manual states its allowed for towing, its automatic transmission is
designed to select automatically the correct gear for the best towing comfort and
performance as the incline increases. To maintain speed or avoid up and down shifts,
manually sh ift to a lower gear as needed. The added weight of a trailer places an
increased load on the engine and cooling system, so monitor your coolant
temperature gauge and automatic transmission fluid temperature gauge (if

IF YOUR ENGINE OVERHEATS
A moderate increase in engine operating temperature is normal when towing a trailer.
If, however, the coolant temperature gauge reading is abnormally high, or if you are
experiencing a significant loss of power, or if you hea r unusual engine noises,* the
engine may be overheating and you should immediately take the following steps:

1. Pull your vehicle safely over to the side of the road, out of t raffic. Apply the
parking brake and move the gearshift lever to NEUTRAL (manual) or PARK
(automatic). DO NOT STOP THE ENGINE.

2. Turn off the air conditioning and, after opening all the windows, turn the heater
on to maximum hot and the fan to its highest speed , and exit the vehicle. The
heater core in your vehicle is just like a miniature engine radiator and will provide
an extra cooling surface to help reduce engine temperature.

*See your vehicle owner’s manual for additional indications that your vehicle may be
overheating.

3. If the temperature does not d rop or continues to increase, stop t he engine
immediately.

4. Being cautious of traffic, step out of the vehicle and, from a safe distance, look
for steam underneath the engine. If you see steam or leaking coolant, sta nd
clear to avoid being burned and s hut off your engine immediately and allow it to
cool. If there is no steam, open the hood.

WARNING - Never remove the radiator cap when the radiator is hot. If the cap is
removed under these conditions, pressurized hot wate r/coolant may spurt out,
possibly causing seriou s injury.

5. As soon as the engine has cooled to its normal operating temperature, visually
inspect the drive belts for damage or looseness. A loose belt reduces water
pump efficiency.


WARNING - Be careful to keep your h ands, hair, jewelry, and clothing clear of the
running drive belt and other moving parts when inspecting the engine and radiator.
Also check to see if the cooling fan is running, and inspect the water pump, radiator,
and radiator hoses for leaks. Keep in m ind, too, that if your vehicle is equipped with
an electric fan motor, it may start without warning any time the coolant temperature
is high. If you find leaking coolant, a loose or missing drive belt, or an inoperable fan,
turn off the engine immediate ly.

6. If no leaks are apparent and all other components appear to be operating
properly with the engine cooled to its normal operating temperature ; check the
coolant level in the reservoir tank with the engine running. Add coolant to the
reservoir tank i f needed. At this point, if repairs are required, go to the nearest
INFINITI retailer . See the IN CASE OF EMERGENCY section of your vehicle owner’s
manual for additional information on overheating.

NOTE – All INFINITI vehicle s have an engine protection mo de which helps reduce the
chance of engine damage if the engine coolant reaches a specified temperature.

NOTES













Passenger Vehicles – INFINITI cautions that you do not tow a trailer with Q50, Q60, Q70 ,
vehicle s.

Cross- Over Vehic les – INFINITI cautions that you do not tow a trailer QX30, QX50, or the
QX70 2WD vehicles.

Other Recommendations and Information – Towing performance and speed are
affected by vehicle payload, tow weight, road grades, and weather conditions,
including h igh temperatures. See your vehicle owner’s manual for details.

TOWING GLOSSARY


BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver.
BRE AK AWAY SWI TCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if it should accidentally become separated from the tow vehicle.
1. Maximum Trailer Weight values are calculated assuming a base
vehicle with driver and any options required, to achieve the
rating. Additional passengers, cargo and/or optional equipment
will add weight to the vehicle and reduce your vehicle’s
maximum towing capacity and trailer tongue load.

2. In general, a weight -distributing hitch system (Class IV) should be
used when towing over 5,000 lbs.
3. Most states require a separate braking system on trailers with a
loaded weight above a specific amount. Check local ordinances.
7- pin connector trailer wire harnesses are required for use with
trailer brakes (available separately).
