SAFETY
SAFETY
Protecting Larger Children
When a child is too big for a child seat, secure the child in a rear sea\
t using the
lap/shoulder seat belt.
Have the child sit upright and all the way back, then ensure the followi\
ng:
• The child’s knees bend comfortably over the edge of the seat.
• The shoulder belt crosses between the child’s neck and arm.
• The lap part of the seat belt is as low as possible, touching the child’s thighs.
• The child can stay seated for the whole trip.
If a lap/shoulder belt cannot be used properly, position the child in a booster seat
in a rear seating position. For the child’s safety, check that the child meets the
booster seat manufacturer’s recommendations.
Some U.S. states and Canadian provinces/territories require children to \
use a
booster seat until they reach a given age or weight (e.g., 6 years or 6\
0 lbs). Be sure
to check current laws in the state or province/territory where you inten\
d to drive.
Allowing a child age 12 or under to sit in the front can result in injur\
y or death
if the passenger’s front airbag infl ates.
If a larger child must ride in front, move the vehicle seat as far to th\
e rear as
possible, then have the child sit up properly and wear the seat belt pro\
perly,
using a booster seat if needed.

4. Once the engine has cooled down, inspect the coolant level and check the\
cooling system components for leaks. If the coolant level in the reserve\
tank
is low, add coolant until it reaches the MAX mark. If there is no coolant in t\
he
reserve tank, make sure the radiator is cool, then cover the radiator ca\
p with a
heavy cloth and open the cap. If necessary, add coolant up to the base of the
fi ller neck, and put the cap back on.
Once the engine has cooled suffi ciently, restart it and check the temperature gauge.
If the temperature needle has gone down, resume driving. If it has not g\

Engine Coolant
Park the vehicle on level ground. Check the reserve tank and the coolant\
level in the
radiator. We recommend Honda Long Life Antifreeze/Coolant Type 2.
Checking the Reserve Tank
1. Check the amount of coolant in the reserve tank.
2. If the coolant level is below the MIN mark, add the specifi ed coolant until it reaches the MAX
mark.
3. Inspect the cooling system for leaks.
Adding Coolant 1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counterclockwise and relieve any pressure in the coolant system. Do
not push the cap down when turning.
3. Push down and turn the radiator cap counterclockwise to remove it.
4. The coolant level should be up to the base of the fi ller neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it fully.
6. Pour coolant into the reserve tank until it reaches the MAX mark. Put the cap back on the reserve
tank.
If temperatures consistently below −22°F (−30°C) are expec\
ted, the coolant
mixture should be changed to a higher concentration. Consult a dealer fo\
r details
for more information.
