3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90" Fahrenheit (32'Celsius) with a loaded vehicle and trailer.
Stopping after high-speed driving.
Idling for long periods in stop and go traffic.
If "ENGINE HOT A/C COMPRESSOR OFF" message appears on the
Driver Information Center, do not be alarmed. This is a normal function
designed to reduce the load on the engine and cooling system you can
continue to drive your vehicle.
If "ENGINE COOLANT HOT" message appears on the Driver
Information Center, pull off to the side of the road as soon as it is safe to
do so. When the vehicle is at a complete stop, shift the transmission
selector to P (Park) and allow the engine to idle. Do not turn off the
engine or increase engine speed above a normal idle. Within two or three
minutes the system should cool sufficiently to allow A/C operation to
resume. At that time resume driving at a reduced speed. Return to
normal driving after 10 minutes if the "ENGINE COOLANT HOT"
message is not displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you're pulling a trailer.
See the Maintenance Schedule for more on this. Things that are
especially important in trailer operation are automatic transaxle fluid
(don't overfill), engine oil, belts, cooling system, and brake wear. Each of
these is covered in this manual, and the Index will help you find them
quickly. If you're trailering, it's a good idea to review these sections
before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
