1 When Driving
When you set the power mode to ON, you may feel
as if the brake pedal is sinking down. This is normal.1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear defogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If exhaust system sounds abnormal or you can smell
exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.

1Shift OperationNOTICEWhen you change
(D to
(R and visa versa, depress
the brake pedal to come to a complete stop, then
select the intended gear position while maintaining
brake pressure.
Use the gear position indicator and the shift button
indicator to check the gear position before selecting
a shift button.
If the indicator of the currently selected gear position,
or all the gear position indicators are blinking
simultaneously, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut off if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happens, you may experience a
slight jolt.
When the engine speed is increased while the
transmission is in
( N, (P or
(R, the fuel supply may
be cut off even without the engine speed entering
the tachometer’s red zone.
The beeper sounds once when you change to
