When Driving
Starting the Engine
1.Make sure the parking brake is applied.
2. Check that the shift lever is in
(P, then
depress the brake pedal.
u Although it is possible to start the vehicle
in
(N, it is safer to start it in (P.
3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.
1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in thinner
air found at altitudes above 8,000 feet (2,400 meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear de fogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Cons ult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the batte ry in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 409
The engine may not start if the keyless access remote
is subjected to strong radio waves.
You do not need to hold the ENGINE START/STOP
button to start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.

from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have
the transmission fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km).
*5: If you drive regularly in very high temperatures (over 110 °F, 43 °C), in very low temperatures (under -
20 °F, -29 °C), or tow a trailer, replace every 60,000 miles/100,000 km.

uuMaintenance Under the Hood uEngine Coolant
Maintenance
Engine Coolant
This coolant is premixed with 50% antifreeze 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 first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
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.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
If temperatures consistent ly below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Cons ult a dealer for more
information.
If Acura antifreeze/coolant is not available, you may
use another major brand non- silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Acur a 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. They may not be compatible
with the coolant or with the engine components.

uuOverheating uHow to Handle Overheating
Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■Last thing to do
Once the engine has cooled sufficiently, re start it and check the temperature gauge.
If the temperature needle has gone down, resume driving. If it has not gone down,
contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergen cy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
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.
