Maintenance
Inverter 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 inverter coolant level every time you refuel.
Have a dealer replace the inverter coolant.
1.Check the fluid level in the tank.
2. If the coolant level has dropped below the
MIN level, have your ve hicle serviced at a
dealer.
u Only a properly trained technician can
refill the coolant and check the system
for leaks.
Specified coolant: Ac ura Long Life Antifreeze/Coolant Type 2
■Checking the Coolant
1Inverter Coolant
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout –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 Acura 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-Ac ura coolant can result in
corrosion, causing the coo ling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. Th ey may not be compatible
with the coolant or with the motor components.

Brake Fluid
The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
Refilling Window Washer Fluid
If the washer fluid is low, a message appears on the MID.
Pour the washer fluid carefully. Do not overflow the reservoir.
Specified fluid: Acura Heavy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake 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-Acura brake fl uid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Acura 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
Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehi cle for scratches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic inte rmittent wipers, turn the wipers off.
■Washing the Vehicle
■Using an Automated Car Wash
1Washing the Vehicle
Do not spray water into the air intake vents. It can
cause a malfunction.
Do not spray water onto the capless unit when the
fuel fill door is open. It ca n cause damage to the fuel
system or engine.

Maintenance
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Promptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.

Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windsh ield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of the
vehicle’s airbags or may be propelled into you or another occupant if the airbags
deploy.
• Be sure electronic accessories do not overload electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 648
•Before installing any electro nic accessory, have the installer contact a dealer for
assistance. If possible, have a deal er inspect the final installation.

Maintenance
Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Acura parts or accessories that may have a similar
effect.
Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is prop erly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, prov ince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Acura has appr oved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.
Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical systems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle’s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Acura high-
voltage battery assembly. Genuine Acur a high-voltage battery assemblies are
designed to work with your vehicle's hybrid power system and have been designed,
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have be en similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

NOTICE
Do not operate the temporary tire repair kit compressor
for more than 15 minu tes. The compressor can
overheat and become permanently damaged.
There are three accessory power sockets:
•In the console compartment•In the front of the center pocket•In the left side panel in the cargo area 2 Accessory Power Sockets P. 216
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usin g the gauge, turn the air
compressor off only after the sealant injection is
complete.

Running the engine with the vehicle in an
enclosed or even partly enclosed area can
cause a rapid build-up of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.

system, then open the hood.1.Pull up on the engine cover, remove it from
the pins.
u Start on the passenger side and lift up on
the outermost edge of the cover.
u Move towards the driver side while
applying uniform upward pressure.
2. Connect the first jump er cable to your
vehicle’s 12-volt battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than 15
volt. Check the charger manual for the
proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1Jump Starting
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
12-volt Battery performa nce degrades in cold
conditions and may prevent the engine from starting.
3WARNING
A 12-volt battery can explode if you do not
follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the 12-volt battery.
