Towing a Trailer

Spare Vehicle Tire
When towing a trailer, you should carry a full-size wheel and tire as aspare in case you have a flat. If you
use the compact spare tire that came
with the vehicle, it may adversely affect vehicle handling. See page 317 for information on proper tire
size, and page 293 for information on
how to store a full-size tire. When storing a full-size spare tire in the
trailer, follow the trailer maker's
instructions.

Additional Trailer equipment
Many states and provinces require
special outside mirrors when towing
a trailer. Even if they don't, you should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.
Ask your trailer sales or rental agency if any other items are
recommended or required for your
towing situation. Pre-Tow Checklist
When preparing to tow, and before driving away, be sure to check the
following:
The vehicle has been properlyserviced, and the tires, brakes,
suspension, and cooling system
are in good operating condition.
All weights and loads are within limits (see pages 212 and 213).
The hitch, safety chain, and any other attachments are secure.
All items on and in the trailer are properly secured and cannot shift
while you drive.
The lights and brakes on your vehicle and the trailer are workingproperly. Your vehicle tires and spare are
properly inflated (see page 317),and the trailer tires and spare are
inflated as recommended by the
trailer maker.
You may want to fill the fuel tank with premium fuel. Premium fuelprovides improved performance.

Cooling System
Adding Engine Coolant

If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line. Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
Antifreeze/Coolant. If it is not available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it is a high-quality coolant
recommended for aluminum engines.
However, continued use of any non-
Honda coolant can result in
corrosion, causing the coolingsystem to malfunction or fail. Have
the cooling system flushed and refilled with Honda antifreeze/
coolant as soon as possible. If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.

Maintenance

Removing the radiator cap
while the engine is hot can cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.

Cooling System

1. Make sure the engine and radiator
are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turning
counterclockwise.
4. The coolant level should be up to
the base of the filler neck. Addcoolant if it is low.
5. Put the radiator cap back on. Tighten it fully.
6. Pour coolant into the reserve tank. Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or
engine components.

Cooling System

Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the timeand distance recommendations in
the maintenance schedule. Only use Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic.
1. Turn the ignition ON (II). Turn
the heater temperature controldial fully clockwise. Turn the
ignition off.
Open the hood. Make sure the
engine and radiator are cool to the

touch.

2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will drain through thesplash guard. Loosen the drain
bolt.
