Driving
■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC with LSF accelerates your
vehicle to the set speed, and then maintains it.
■When you depress the accelerator pedal
You can temporarily increase th e vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC with LSF range.
ACC with LSF stays on unless you cancel it. Once you release the accelerator pedal,
the system resumes an appropriate speed for keeping the following-interval while a
vehicle ahead is within the ACC with LSF range.
■A vehicle detected ahead is within AC C with LSF range and slows to a stop
Your vehicle also stop s, automatically. The
Stopped message appears on the driver
information interface and the head-up
display.
When the vehicle ahead of you starts again,
the vehicle icon on th e driver information
interface blinks. If you press the RES/+ or
−/SET button, or depress the accelerator
pedal, ACC with LSF operates again within the
prior set speed.
1 When in Operation
Limitations
You may need to use the brake to maintain a safe
interval when using ACC wi th LSF. Additionally, ACC
with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations
P. 395
3WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in the ve hicle moving without
operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with LSF.
A vehicle icon with dotted-line
contour appears on the driver
information interface
1 When you depress the accelerator pedal
While the accelerator pedal is depressed, the system
does not apply the brakes to keep the following
interval, as well as the BRAKE message on the driver
information interface does not appear.

Driving
■The system operation is suspended if
you:
• Set the wipers to continuous operation.
u Turning the wipers off resumes the
LKAS.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
■The LKAS may automatica lly be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exist, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the driver
information interface and the
head-up display change to
contour lines, and the beeper
sounds (if activated).

uuWhen Driving uTire Pressure Monitoring System (TPMS)
Continued
Driving
Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will caus e the low tire pressure/TPMS indicator to
come on and a message to appear on the driver information interface.
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.
2 Checking Tires P. 468
Make sure:
•The vehicle is at a complete stop.
• The gear position is in
(P.
• The power mode is in ON.
■TPMS Calibration
1Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire. 2 Checking and Maintaining Tires P. 468
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the
steering wheel.
•You drive on snowy or slippery roads.
•Tire chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
•There is a heavier and uneve n load on the tires than
the condition at calibration.
•Tire chains are used.

uuWhen Driving uFC System in Extreme Cold-weather Conditions
Driving
FC System in Extreme Cold-weather Conditions
The FC system may behave differently on cold days. It may operate a special process
to improve start-up performance and dura bility. Operation noises, purge process
while parked, etc., differ from usual. However, this is not a malfunction.
On cold days, the power output may be temporarily limited if the vehicle is driven at
high vehicle speeds or accelerated suddenly before the FC system warm-up is
completed. Operate the vehi cle looking out for the surrounding traffic until the FC
system reaches full ope rating temperature.
If the exhaust pipe is blocked, the power system may stop. In especially cold
weather, freezing prevention process wh ile parked may not be able to be
performed. Also, the process cannot be carry out if the 12-volt battery terminals are
disconnected; consequently, the FC st ack (fuel cell body) may deteriorate.
On cold days, the hydrogen gas may be consumed faster than usual.
On cold days, when the power system op erates starting/stopping processes or
freezing prevention process while parked, wa ter vapor in the exhaust may appear as
a white mist emitted from the exhaus t pipe. This is not a malfunction.
1FC System in Extreme Cold-weather Conditions
3CAUTION
When the power system operates stopping
process or freezing prevention process
while parked in cold weather, a puddle of
discharged water may form on the ground
and become frozen. Be careful not to slip
on it.

uuWhen Driving uFC System in Extreme Cold-weather Conditions
Driving
On cold days, you may get sprayed with exhaust water if standing behind the vehicle
when:
• The FC system is idling until the READY indicator comes on at power system
start-up.
• The FC system is in the shutdown process after it was stopped before warm-up is
completed.
High Voltage battery is warmed up using the air inside the vehicle. If the air
conditioner is not used or a window is op en, it may take time to complete warm-up.
As a result, the power output may be limited or the READY indicator may take
longer than usual to turn on.
When the power system is tu rned on in extremely cold temperatures between –4°F
and –22°F (–30°C and –20°C), its standby operation noise may become louder than
in normal low temperatures.1 FC System in Extreme Cold-weather Conditions
If the temperature of the fuel cell drops below –4°F
(–20°C), the power system may not start. If the
temperature drops to belo w –22°F (–30°C), the fuel
cells or the High Voltage ba ttery will not operate and,
as a result, the vehicle will not start.

Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.
Pull the electric parkin g brake switch up gently
and securely.
u The parking brake and brake system
indicator (red) comes on.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the motor compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 506
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the
vehicle comes to a stop. The electric parking
brake then applies, and the switch should be
released.
