may not start.
 When the Engine Start/Stop button is in the ACC or ON position, if any
door is open, the system checks for
the smart key. If the smart key is not
in the vehicle, the " " indicator
will blink and the warning "Key not

are closed, the chime will also sound
for about 5 seconds. Keep the smart
key in the vehicle when in the ACC
position or if the hybrid system is
ON. 1. Always carry the smart key with
you.
2. Make sure the parking brake is applied.
3. Make sure the shift lever is in P (Park).
4. Depress the brake pedal.

Shift-lock system
For your safety, the automatic trans-
mission has a shift-lock system
which prevents shifting the transmis-
sion from P (Park) into R (Reverse)
unless the brake pedal is depressed.
To shift the transmission from P
(Park) into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the hybrid system or placethe Engine Start/Stop button in the ON position.
3. Move the shift lever.
Shift-lock release
If the shift lever cannot be moved
from the P (Park) position into R
(Reverse) position with the brake
pedal depressed, continue depress-
ing the brake, and then do the follow-ing: 1. Place the Engine Start/Stop but-
ton in the OFF position.
2. Apply the parking brake.
3. Carefully remove the cap (1) cov- ering the shift-lock access hole.
4. Insert a tool (e.g. flathead screw- driver) into the access hole and
press down on the tool.
5. Move the shift lever while holding down the screwdriver.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the hybrid system is not on or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the hybrid system is not on,
the reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.Do not depress the brake pedal
continuously without the " "
indicator ON. The battery may be
discharged.
NOTICE
BBRRAA KKIINN GG SS YY SSTT EEMM
Take the following precautions:
Do not drive with your foot resting on the brake pedal.This will create abnormal high
brake temperatures, exces-sive brake lining and pad
wear, and increased stoppingdistances.
When descending down a
long or steep hill, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speedwithout using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheatand could result in a tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle’s ability to safely slow
down; the vehicle may alsopull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heatup the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at highspeeds until the brakes func-
tion correctly.

Do not apply the acceleratorpedal while the parking brake is
engaged. If you depress theaccelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
brake may occur.
Driving with the parking brake on can overheat the braking sys-tem and cause premature wear
or damage to brake parts. Makesure the parking brake is
released and the Brake Warning
Light is off before driving. Check the Parking
Brake Warning Light
by placing the Engine
Start/Stop button tothe ON position (do
not start the hybrid
system).
This light will be illuminated when the
parking brake is applied with the
Engine Start/Stop button in the
START or ON position.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while hybrid system is ON,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.
NOTICE
Whenever leaving the vehicle
or parking, always come to a
complete stop and continueto depress the brake pedal.
Move the shift lever into the P
(Park) position, then apply the
parking brake, and place the
Engine Start/Stop button inthe OFF position.
Vehicles with the parking
brake not fully engaged are at
risk for moving inadvertently
and causing injury to yourself
or others.
NEVER allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If theparking brake is released
unintentionally, serious injury
may occur.
Only release the parking
brake when you are seated
inside the vehicle with your
foot firmly on the brake pedal.
