MAINTENANCE

Engine Coolant

Park the vehicle on level ground. Check the reserve tank and the coolant level in the
radiator. We recommend Acura 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 specified coolant until it reaches the MAX
mark.
3. Inspect the cooling system for leaks.
NOTICE
If temperatures consistently below −22°F (−30°C) are expected, the coolant
mixture should be changed to a higher concentration. Consult your dealer for
more information.
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
filler 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.
WARNING
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.
NOTICE
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills
immediately; they can damage components in the engine compartment.

Window Washer Fluid

Check the amount of window washer fluid using the
1/2 mark on the reservoir. If the level is low, fill the
washer reservoir. Pour the washer fluid carefully. Do
not overflow the reservoir.
Canadian models
If the washer fluid is low, a message appears on the
multi-information display.
NOTICE
Do not use engine antifreeze or a vinegar/water solution in the windshield
washer reservoir. Antifreeze can damage your vehicle's paint. A vinegar/water
solution can damage the windshield washer pump.

Brake Fluid

The fluid level should be between the MIN and MAX marks on the side of the
reservoir. We recommend using Acura Heavy Duty Brake Fluid DOT 3.
Pour the fluid carefully.
If the fluid level is at or below the MIN mark, have a
dealer inspect for leaks or worn brake pads as soon as
possible.
NOTICE
Brake fluid marked DOT 5 is not compatible with your vehicle's braking system
and can cause extensive damage.

Checking the Battery

Check the battery terminals for corrosion monthly.
For jump starting, see page 114.
WARNING
The battery gives off explosive hydrogen gas during normal operation.
A spark or flame can cause the battery to explode with enough force to kill or
seriously hurt you.
When conducting any battery maintenance, wear protective clothing and a
face shield, or have a skilled technician do it.
WARNING: Battery posts, terminals, and related accessories contain lead and lead
compounds. Wash your hands after handling.
