Maintenance
Engine Coolant
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ho nda Long Life Antifreeze/Coolant Type 2
■Checking the Coolant
1Engine Coolant
NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about −31°F (−35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult a dealer for
details.
If Honda antifreeze /coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda anti freeze/coolant as soon as
possible.
3WARNING
Removing the reserve tank 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 reserve tank
cap.

Maintenance
Brake/Clutch* Fluid
Use the same fluid for both the brakes and clutch*.
The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
The brake fluid reserve tank is also used for
your vehicle’s clutch fluid. As long as you keep
the brake fluid level as in structed above, there
is no need for checking the clutch fluid level.
Specified fluid: Honda Heavy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake/Clutch* Fluid
NOTICE
Brake fluid marked DOT 5 is not compatible with your
vehicle’s braking system and can cause extensive
damage.
If the specified br ake fluid is not av ailable, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Honda brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Honda Heavy
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN mark,
have a dealer inspect the vehicle for leaks or worn
brake pads as soon as possible.

Maintenance
Refilling Window Washer Fluid
Open the cap and check the amount of
window washer fluid.
If the level is low, fill the washer reservoir.
If the washer fluid is low, a message appears
on the driver information interface.
Pour the washer fluid carefully. Do not
overflow the reservoir.1Refilling Window Washer Fluid
NOTICE
Do not use engine antifreeze or a vinegar/water
solution in the windshield washer reservoir.
Antifreeze can damage y our vehicle's paint. A
vinegar/water solution ca n damage the windshield
washer pump.
Use only commercially avai lable windshield washer
fluid.
Avoid prolonged use of hard water to prevent lime
scale build up.

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is ex posed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pre ssure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular in spections and inflation pres sure maintenance, it is
recommended that you have annual inspecti ons performed once the tires reach five
years old. All tires, including the spare
*, should be removed from service after 10
years from the date of manufacture, regard less of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (over 137 mph or 220
km/h), adjust the cold tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure.

uuChecking and Maintaining Tires uWinter Tires
Maintenance
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the
chains listed below:
*1: On 245/30ZR20 tires, you cannot install any type of tire chains. If you have to use
tire chains, replace the original tires with the 235/40R18 tires.
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.

uuChecking and Maintaining Tires uCold Weather Driving
Maintenance
Cold Weather Driving
Summer Only tires and Ultra High Perform ance (UHP) tires are very sensitive to
ambient temperatures and are designed to be used at temperatures above 45°F
(7°C). If the vehicle is operated with Summe r Only tires or UHP tires at temperatures
below 45°F (7°C), the tires will provide decreasing amounts of grip and other
performance attributes. If the vehicle is operated with Summer Only tires or UHP
tires at temperatures below –4°F (–20°C), th e tire tread may lose their elasticity and
become brittle, resulting in permanent damage to the tread. A damaged tire may
fail during use. Therefore, if you operate the vehicle when ambient temperatures are
below 45°F (7°C), we recommend that yo u install other tires (e.g., mud+snow,
winter) that are designed to provide a ppropriate performance attributes under the
anticipated conditions.

45°F (7°C) may lead to a loss of
performance and control, which could
result in a crash, se rious injury or death.
