uuParking Your Vehicle uCross Traffic Monitor*
Driving
Cross Traffic Monitor*
Monitors the rear corner areas using the radar sensors when reversing, and alerts
you if a vehicle approaching fro m a rear corner is detected.
The system is convenient when you are backing out of a parking space.1 Cross Traffic Monitor*
3CAUTION
Cross Traffic Monitor cannot detect all
approaching vehicles and may not detect
an approaching vehicle at all.
Failure to visually confirm that it is safe to
back up the vehicle before doing so may
result in a collision.
Do not solely rely on the system when
reversing; always also use your mirrors, and
look behind and to the sides of your vehicle
before reversing.
* Not available on all models

uuParking Your Vehicle uCross Traffic Monitor*
Driving
The system activates when:
• The power mode is in ON.
• The Cross Traffic Monitor system is turned
on.
2 Cross Traffic Monitor On and Off P. 509
•The shift lever is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not detect or provide alerts for a vehicle that is moving away from
your vehicle, and it may not detect or ale rt for pedestrians, bicycles, or stationary
objects.
■How the System Works1 Cross Traffic Monitor*
Cross Traffic Monitor may not detect an approaching
vehicle, or may delay aler ting you under the following
conditions:
•A vehicle, which is parked adjacent to your vehicle,
is blocking the radar sensor’s view.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 and 16 mph (10 and 25 km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.•Your vehicle is tilt ed due to a heavy load in the rear.
•The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed. Have a vehicle checked by a dealer.
For proper operation, always keep the rear bumper
corner area clean.
Do not cover the rear bumper corner area with labels
or stickers of any kind.

The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
Refilling Window Washer Fluid
Check the amount of window washer fluid.
If the level is low, fill the washer reservoir.
If the washer fluid is low, a message appears on the multi-information display.
Pour the washer fluid carefully. Do not overflow the reservoir.
Specified fluid: Honda 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 brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Honda brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Honda 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
Battery
Checking the Battery
The condition of the battery is monitored by a sensor located on the negative
terminal of the battery. If there is a prob lem with this sensor, the multi-information
display will display a warning message. If this happens, have you vehicle inspected
by a dealer.
Check the battery termin als for corrosion monthly.
If your vehicle’s battery is disconnected or goes dead:
• The audio system is disabled.
2 Audio System Theft Protection P. 203
•The clock resets.
2 Clock P. 110
Charging the Battery
Disconnect both battery cables to prevent da maging your vehicle’s electrical system.
Always disconnect the negative (–) cable first, and reconnect it last.
1 Battery
WARNING: Battery post, terminals,
and related accessories contain lead
and lead compounds.
Wash your hands after handling.
If you find corrosion, clea n the battery terminals by
applying a baking powder a nd water solution. Clean
the terminals with a damp towel. Cloth/towel dry the
battery. Coat the terminals with grease to help
prevent future corrosion.
3WARNING
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 prot ective clothing and
a face shield, or have a skilled technician do
it.

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 possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
1Changing a Flat Tire
Follow compact spare precautions:
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 us e 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-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.

uuIf a Tire Goes Flat uChanging a Flat Tire
Handling the Unexpected
If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator
comes on while you are driving. After dr iving for a few miles (kilometers), the
indicator will start blinking for a short time and then stay on. Tire Pressure
Monitor Problem appears on the multi-informatio n display, but this is normal.
If you replace the tire with a specified regular tire, the warning message on the
multi-information display and the low tire pressure/TPMS indicator will go off after
a few miles (kilometers).
■TPMS with Tire Fill Assist and the Compact Spare Tire1 TPMS with Tire Fill Assist and the Compact Spare Tire
The system cannot monitor th e pressure of the spare
tire. Manually check the spare tire pressure to be sure
that it is correct.
Use the TPMS specific wheels. Each is equipped with
a tire pressure sensor mount ed inside the tire behind
the valve stem.
