Seat Belt Inspection
Regularly check the condition of your seat belts as follows:
• Pull each belt out fully, and look for frays, cuts, burns, and wear.
• Check that the latch plates and buckle s work smoothly and the belts retract
easily.
u If a belt does not retract easily, cleanin g the belt may correct the problem. Only
use a mild soap and warm water. Do not use bleach or cleaning solvents. Make
sure the belt is completely dry before allowing it to retract.
Any belt that is not in good condition or working properly will not provide proper
protection and should be replaced as soon as possible.
A belt that has been worn during a crash may not provide the same level of
protection in a subsequent crash. Have your seat belts inspected by a dealer after
any collision.1 Seat Belt Inspection
3WARNING
Not checking or maintaining seat belts can
result in serious injury or death if the seat
belts do not work properly when needed.
Check your seat belts regularly and have
any problem corrected as soon as possible.

Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on th e windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheel s, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, check for damage and excessive wear.
2 Checking and Maintaining Tires P. 548
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you've parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause elec trical component failure.
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■In Rain
■Other Precautions
1 Precautions While Driving
NOTICE
Do not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the ignition switch is turned to ACCESSORY
( q*1
while driving, the engine will shut down and all
steering and brake power a ssist functions will stop,
making it difficult to control the vehicle.
Do not select
( N while driving as you will lose engine
braking (and accelera tion) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.

For the CMBS to work properly:
•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing powder
for cleaning the sensor cove r. Clean it with water
or a mild detergent.
•Do not put a sticker on th e radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the syst em by using the CMBS OFF
button and take your vehicle to a dealer.

uuBraking uBrake System
496
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps to reduce the effort needed on the brake pedal. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when braking very hard.
2 Brake Assist System P. 500
2 Anti-lock Brake System (ABS) P. 499
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibration of the brake pads against
the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
speed position.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.

Continued
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.
