Power Outlet
ORG3050074
The power outlet is designed to provide
power for mobile telephones or other
devices designed to operate with vehicle
electrical systems. The devices should
draw less than 180 watts with the engine
running.
WARNING
Avoid electrical shocks. Do not place
your fingers or foreign objects (pin, etc.)
into a power outlet or touch the power
outlet with a wet hand.
NOTICE
To prevent damage to the Power
Outlets:
• Use the power outlet only when the
engine is running and remove the
accessory plug after use. Using the
accessory plug for prolonged periods
of time with the engine off could
cause the battery to discharge.
• Only use 12 volts electric accessories
which are less than 180 watts in
electric capacity.
• Adjust the air-conditioner or heater
to the lowest operating level when
using the power outlet.
• Close the cover when not in use.
• Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static and
malfunctions in other electronic
systems or devices used in your
vehicle.
• Push the plug in as far as it will go. If
good contact is not made, the plug
may overheat and the fuse may open.

4. Remove the cap-cover (1) and press
the button (2) while depressing the
brake pedal.
Then, the gear will change to the
N (Neutral) position. The button
(2) operates only for 20 seconds to
change the gear between P (Park) and
N (Neutral) from the time when the
button (2) is first pressed. However,
the button must be pressed within 3
minutes after the engine is turned off.
Information
In situations when the gear needs to be
shifted from P (Park) to N (Neutral) when
the Engine Start/Stop button is in the OFF
position, refer to step 4.
Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the transmission
from P (Park) into R (Reverse) or D (Drive)
unless the brake pedal is depressed.
To shift from P (Park) or N (Neutral) into R
(Reverse) or D (Drive):
1. Depress and hold the brake pedal.
2. Start the engine.
3. Shift gear while depressing the brake
pedal.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Shift the gear to P (Park), apply the
parking brake, and press the Engine
Start/Stop button to the OFF position.
Take the Key with you when leaving the
vehicle.
WARNING
• When you stay in the vehicle with
the engine running, be careful not
to depress the accelerator pedal for
a long period of time. The engine or
exhaust system may overheat and
start a fire.
• The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
• Do not stop or park over flammable
materials, such as dry grass, paper
or leaves. They may ignite and cause
a fire.

Paddle Shifter (Manual Shift
Mode)
ORG3060011
The paddle shifter allows the driver to
shift gear without taking one’s hands off
the steering wheel.
The paddle shifter operates as follow.
• Pull the [+] or [-] paddle shifter once
to shift up or down one gear and the
system changes from automatic shift
mode to manual shift mode.
• To change back to automatic shift
mode from manual shift mode, do one
of the following:
-Pull the [+] paddle shifter for more
than one second.
-Drive the vehicle under 4 mph (7
km/h)
-Gently depress the accelerator
pedal for more than 6 seconds.
-Rotate the shift dial to the D (Drive)
position.
Information
If the [+] and [-] paddle shifters are pulled
at the same time, gear shift may not occur.
Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear into P (Park) when
the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
• Do not shift the gear to N (Neutral)
when driving. If the gear is shifted to
N (Neutral) while driving, the vehicle
loses the ability to provide engine
braking. Doing so may increase the
risk of an accident.
Also, shift the gear back to D (Drive)
while the vehicle is moving may
severely damage the transmission.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.

Power-Assist brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running 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 distance, however, will be
longer than with power brakes.
When the engine is not running, 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.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending down a long or
steep hill, use the paddle shifter
and manually downshift to a
lower gear in order to control your
speed without using the brake
pedal excessively. Applying the
brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle's
ability to safely slow down; the
vehicle may also pull 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 fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
Disc Brakes Wear Indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.
