Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause electrical 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 put the shift lever in
( N, as you will lose
engine braking (and acce leration) 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.

Transmission Fluid
Have a dealer check the fluid level and replace if necessary.
Do not attempt to check or change the continuously variable transmission fluid
yourself.
Have a dealer check the fluid level and replace if necessary.
Do not attempt to check or change th e manual transmission fluid yourself.
■Continuously Variable Transmission (CVT) Fluid
Specified fluid: Honda HCF-2
■Manual Transmission Fluid
Specified fluid: Honda MTF
Continuously variable transmission models
1Continuously Variable Transmission (CVT) Fluid
NOTICE
Do not mix Honda HCF-2 with other
transmission fluids.
Using a transmission fluid other than Honda HCF-2
may adversely affect the operation and durability of
your vehicle’s transmission, and damage the
transmission.
Any damage caused by using a transmission fluid that
is not equivalent to Hond a HCF-2 is not covered by
Honda’s new vehicle limited warranty.
Manual transmission models
1Manual Transmission Fluid
If Honda MTF is not availa ble, you may use the API
certificated SAE 0 W-20 or 5 W-20 viscosity motor oil
as a temporary measure.
Replace with MTF as soon as possible. Motor oil does
not contain the proper addi tives for the transmission
and continued use can cause decreased shifting
performance and lead to transmission damage.

uuMaintenance Under the Hood uBrake/Clutch* Fluid
Maintenance
Brake/Clutch* Fluid
Use the same fluid for both the brakes and clutch*.
The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
The brake fluid reserve tank is also used for
your vehicle’s clutch fluid. As long as you keep
the brake fluid level as in structed above, there
is no need for checking the clutch fluid level.
Specified fluid: Honda Heavy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake/Clutch* 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-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.

uuIndicator, Coming On/Blinking uIf the Brake System Indicator (Red) Comes On or Blinks
Handling the Unexpected
If the Brake System Indicator (Red) Comes On or
Blinks
■Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■What to do when the indicator comes on while driving
Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate action . If necessary, downshift the
transmission to slow the vehicle using engine braking.
■Reason for the in dicator to blink
• There is a problem with the electric parking brake system.
■What to do when the indicator blinks
Avoid using the parking brake and have your vehicle checked by a dealer
immediately.
1 If the Brake System Indicator (Red) Comes On or Blinks
Have your vehicle re paired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe plac e. If necessary downshift
the gears.
If the brake system indicator and ABS indicator come
on simultaneously, the elec tronic brake distribution
system is not working. Th is can result in vehicle
instability under sudden braking.
Have your vehicle inspecte d by a dealer immediately.
If the brake system indicator (red) blinks at the same
time when the brake system indicator (amber) comes
on, the parking br ake may not work.
Avoid using the parking brak e and have your vehicle
checked by a dealer immediately. 2 If the Brake System Indicator (Red) Comes
On or Blinks at the Same Time When the
Brake System Indicator (Amber) Comes On
P. 671
If you repeatedly operate the electric parking brake in
a short period of time, the brake stops operating to
prevent heating of the system and the indicator
blinks.
It returns to its original state in approximately 1
minute.
