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, 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 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.

WARNING -Never remove the radiator cap when the radiator is hot. If the cap is
removed under these conditions, pressurized hot water/coolant 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.


WARNING- 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.

20 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.


NOTES

TOWING GLOSSARY

BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver.
Also commonly called a drawbar.

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).
