SAFETY IS PRIORITY ONE
Obviously, your first concern should be safety. Your vehicle was designed to be used primarily to
carry passengers and cargo. Always remember that towing a trailer places additional loads on your
vehicle’s engine, drivetrain, suspension, steering, braking, and other systems. Therefore, be certain
that your vehicle can meet the demands of the towing application you have in mind.

Rent or purchase only the highest-quality towing and safety equipment you can find. Reinforced tow
hitches designed especially for certain Infiniti vehicles are available from your Infiniti retailer.
Hitches for other Infiniti models — if Infiniti recommends towing with that vehicle — should be
bought from and installed by a professional supplier of towing equipment.

Finally, it is important to follow the towing capacity limit set for your specific vehicle and to ensure
that your vehicle is in top mechanical condition, especially the tires, brakes, suspension, and
engine cooling system. See your vehicle owner’s manual for details.

NEVER EXCEED THE ESTABLISHED TOWING CAPACITY
Towing capacities vary from vehicle to vehicle. See the towing information in your vehicle owner’s
manual for the towing capacities of 2013 Infiniti vehicles produced at the time of Towing Guide
publication. Use this data to help select the proper Infiniti vehicle to meet your anticipated towing
needs, and refer to it when towing, renting a trailer or other piece of towing equipment.

EQUIP YOUR INFINITI FOR TOWING
The frequency and type of towing should influence the manner in which you equip your vehicle. If
you plan to tow often, either for recreation or work, select the engine size, transmission type,
suspension, and towing capacity that are best suited to your requirements. This guide can help you
select the proper equipment.

READ THIS GUIDE BEFORE YOU TOW
This guide was designed to provide an overview of safe towing practices. Here, you will find
information on towing equipment, safety, proper loading and driving techniques, towing tips, and
much more.

It is also a good idea to discuss your towing requirements with either your Infiniti retailer or a
professional supplier of towing equipment before you equip your Infiniti vehicle for towing.
Finally, there are state and local laws on towing that you should review to ensure compliance with
all regulations.

Special Note: Do not use your new vehicle to tow a trailer or haul a heavy load for the first 500 miles
(800 km). Your engine, axle or other parts could be damaged. For the first 500 miles that you tow a
trailer, do not drive over 50 mph and do not make starts at full throttle. This helps your engine and
other parts of your vehicle wear in at heavier loads.

PREPARING YOUR VEHICLE

BREAK-IN AND MAINTENANCE SCHEDULE
Infiniti recommends that you allow a sufficient “break-in” (500 miles) of both the engine and
drivetrain before towing with your new Infiniti vehicle. In addition, for the first 500 miles that you
tow a trailer, do not drive over 50 mph and do not make starts at full throttle.

Keep in mind, too, that towing places higher demands and added loads on vehicle components, so
more frequent maintenance is called for. Your Infiniti Service & Maintenance Guide provides the
accelerated maintenance schedule for towing purposes. Engine oil, filter, transmission oil, and
possibly other fluids should be changed more frequently when towing.

TIRE PRESSURE
When towing a trailer, increase the tow vehicle tire pressures to the recommended cold
specifications. You will find these figures in the vehicle owner’s manual and on the tire pressure
chart located within the vehicle. Trailer tire condition, size, load rating, and inflation pressure must
be in accordance with the trailer and tire manufacturer’s specifications.

MEASURING VEHICLE WEIGHT
The key to safe, efficient towing has to do with weight. Your vehicle — SUV, crossover, or passenger
car — is capable of carrying and towing only a certain amount of weight. You must compare your
vehicle’s tow weight ratings with the combined weight of the vehicle, trailer, and their contents.
This will help ensure that the total weight does not exceed any of your vehicle’s tow weight ratings.
There are four weights to consider when towing:
Š Gross Vehicle Weight
Š Gross Axle Weight (Front and Rear)
Š Gross Combined Weight
Š Trailer Tongue Load

These ratings are based upon normal highway driving and may be reduced if operating in reduced-
traction situations, for example, slippery boat ramps.

NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and the trailer tongue load
specified could adversely affect vehicle handling, braking, and performance. Damage to your
vehicle resulting from overloading may not be covered by your vehicle warranty.












GROSS VEHICLE WEIGHT (GVW)
The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo, fuel,
hitch, trailer tongue weight, and any optional equipment.

The best way to determine the GVW is by having the
vehicle — loaded and ready to tow — weighed
at a public scale. To that figure, add the combined weight
of all passengers. Then, add the trailer tongue weight to
determine the approximate GVW.

The GVW you come up with must not exceed the Gross
Vehicle Weight Rating (GVWR) for your vehicle. On all
Infiniti vehicles, the GVWR is shown on the Federal Motor
Vehicle Safety Standard (F.M.V.S.S.) certification label
located in the driver’s-side door area.

To avoid overloading the vehicle, be sure to include the
trailer tongue weight as a part of the cargo when
determining how much weight can be safely carried
inside the vehicle. The weight of the roof rack cargo
should also be included.

Towing can significantly alter the handling and performance characteristics of your vehicle. Plus, it
puts increased strain on the engine and drivetrain. Therefore, it is always a good idea to approach
towing from the standpoint of safety — whether you are purchasing equipment or actually pulling
the trailer.

Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to tow. Buy or
lease only quality equipment. In addition, be certain that you have all of the equipment needed for
safe towing, such as safety chains/cables, electric trailer brakes, electric trailer brake controller,
breakaway switch, and extended rear view mirrors.

You should follow a more frequent maintenance schedule and check fluid levels, pressures, tire
condition, etc., more often when on the road. See your vehicle owner’s manual for details.

LOADING YOUR TRAILER
Taking the time to load and balance your trailer properly will improve overall handling and minimize
the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing from side to side,
upsetting vehicle handling. Careful loading and balancing can help eliminate these problems.

As mentioned earlier, conventional trailer tongue load must fall between 10-15% of the total trailer
weight, or within the limits of the maximum trailer tongue load specified by the trailer manufacturer.
Excessive trailer tongue load can actually push down the vehicle in back, lifting the front wheels to
a point where traction, steering response, and braking are severely reduced. Insufficient trailer
tongue load or negative load can lift the trailer tongue upwards on the trailer ball causing instability,
which may lead to “tail wagging” or jackknifing.

With this in mind, proper loading is extremely
important. When loading a trailer, 60% of the total
cargo weight should be positioned in the front
portion of the trailer and 40% in the back. Then the
load should be adjusted until the proper tongue load
ratio is achieved.

PASSENGERS
Never allow passengers to ride inside a trailer while it is being towed. Not only is this unlawful in
most areas, passengers could be seriously injured during sudden trailer movement or in an
accident. In addition, trailers may allow fumes from the tow vehicle to leak inside. This could result
in carbon monoxide poisoning from the engine exhaust.

VEHICLE MODIFICATIONS
Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, or
adding extended mirrors — are not recommended for any Infiniti vehicle being used for towing
purposes. Changes to the drivetrain, suspension, exhaust systems, frame structure/unibody, or
other vehicle components are not necessary for towing within the limits described in this guide.
These changes may diminish the reliability and longevity of your vehicle and damage caused by
such modifications may not be covered under your vehicle’s warranty.

TOOL KIT
When towing, bring tools including flares, a flashlight, emergency reflectors, jumper cables, extra
fuses, extra radiator coolant, oil, and easily replaced spare parts such as taillight bulbs. You should
also carry spare tires for your tow vehicle and trailer, as well as a jack suitable for use on the trailer.
Be aware that not all automotive jacks can be used safely on a trailer.

BEFORE STARTING OUT
Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are the tire
pressures correct? Are the safety chains/cables securely in place? Is the cargo tied down securely?
Do all the lights work? Is the coupler properly attached over the hitch ball and secured using a
locking pin? Is the breakaway switch hooked up and functioning properly? Are vehicle and electric
trailer brakes working properly?

Make a checklist of key items to be inspected. When towing, vehicle engine oil, transmission oil,
and coolant should always be checked before starting out. Finding a potential problem while in
your driveway is better than discovering it miles from home.

rearward vision, have someone outside the vehicle act as a “spotter” to guide you along. Do not
use the Back-up Collision Intervention system (BCI) when towing a trailer.

PARK SMART
A tow vehicle and trailer can be an unwieldy combination in a small 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 your vehicle is
equipped with an automatic transmission, there are some precautions you should take:
Š Have someone block the wheels once the tow vehicle and trailer are in position and being held
by the vehicle’s brake.
Š Next, apply the parking brake and only then move the gear lever into PARK. 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. Never attempt to pass on hills or when
going around curves.

HILLS – UPGRADES
As the incline increases, your vehicle — if equipped with an automatic transmission — is designed
to automatically select the correct gear for the best towing comfort and performance. To maintain
speed or avoid up and down shifts, manually shift 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
equipped) carefully. At the first sign of overheating, pull to the side of the road. See IF YOUR ENGINE
OVERHEATS later in this section for more information.

HILLS – DOWNGRADES
While going downhill, the weight of the trailer pushing on the tow vehicle may decrease overall
stability. Therefore, to maintain adequate control, reduce your speed and shift to a lower gear. If

2013 Infiniti Towing Guide
18
your vehicle is equipped with Tow Mode, see your vehicle owner’s manual for information about the
use of this function.

Avoid long or repeated use of the brakes when descending a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a lower gear instead provides “engine braking” and
reduces the need to brake as frequently.

HIGH-ALTITUDE PERFORMANCE
An engine will lose about 4% of its performance for every 1,000 feet above sea level that you travel.
If you will be towing in high altitudes, it is a good idea to allow more time than usual due to the
engine’s reduced performance.

AUTOMATIC CRUISE CONTROL
Do not use cruise control while towing a trailer.

BLIND SPOT INTERVENTION
Do not use the Blind Spot Intervention system (BSI) when towing a trailer.

TOW MODE (IF EQUIPPED)
Tow Mode is recommended when towing a heavy trailer or hauling a heavy load, in stop-and-go
traffic, rolling terrain, or a busy parking lot. Driving the vehicle in Tow Mode may affect fuel
economy and transmission/engine driving characteristics. See your vehicle owner’s manual for
additional information about Tow Mode.

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 hear 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 traffic. 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. 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 drop or continues to increase, stop the 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, stand clear to avoid being
burned and shut off your engine immediately and allow it to cool. If there is no steam, open
the hood. Never remove the radiator cap when the radiator is hot. If the cap is removed
under these conditions, hot water/coolant under high pressure may spurt out, possibly
causing serious 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. Be careful
to keep your hands, 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 mind,
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 immediately.

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 if 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 vehicles have an engine protection mode which helps reduce the chance of
engine damage if the engine coolant reaches a specified temperature.
