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 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: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
If Honda 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-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant 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.

Maintenance
Transmission Fluid
Check the fluid level when the engine is at normal operating temperature.
1. Park on level ground, and start the engine.
2. Wait until the radiator fan starts and then
turn off the engine.
u Perform step 3 after waiting for about 60
seconds (less than 90 seconds).
3. Remove the dipstick (yellow loop) from the
transmission and wipe it with a clean cloth.
4. Insert the dipstick all the way back into the
transmission securely , as shown in the
image.
5. Remove the dipstick and check the fluid
level.
u It should be between the upper and
lower marks in the HOT range.
6. If the level is below the lower mark, add
fluid into the dipstick hole to bring it to the
level between the upper and lower marks,
and have your vehicle checked by a dealer
immediately.
■Automatic Transmission Fluid
Specified fluid: Acura ATF DW-1 (automatic transmission fluid)

We recommend that you check the power steer ing fluid level every time you refuel.
Check when the engi ne is not running.
1.Look at the side of the reservoir. The fluid
should be between the UPPER LEVEL and
LOWER LEVEL .
2. Add power steering fluid if necessary to the
UPPER LEVEL mark.
u Inspect the system for a leak. If the fluid
level goes below the LOWER LEVEL
frequently, have the system inspected as
soon as possible.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, and non-slippery ground.
2. Put the shift lever in
P.
3. Set the parking brake.
4. Turn on the hazard warn ing lights and turn the ignition switch to LOCK
0*1.
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ig nition switch.
1Changing a Flat Tire
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model.
Do not use them with another vehicle.
Do not use another type of compact spare tire or
wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairing agent on a flat tire,
as it can dama ge the tire pressure sensor.

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, restart it and check the temperature gauge.
If the temperature gauge 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 emergency/temporary measure only.
Have a dealer flush the syst em 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.
