uuWhen Driving uAutomatic Transmission
344Driving
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.Automatic TransmissionThe engine runs at a higher idle speed and creeping increases.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pedal while driving uphill may cause the
transmission to drop to a lower gear, unexpectedly increasing vehicle speed. Depress
the accelerator pedal carefully, especially on slippery roads and curves.■

1Precautions While Driving
Do not put the shift lever in
(N, as you will lose
engine braking (and acceleration) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as to not 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.

The vehicle may move forward very slightly even in

Depress the brake pedal firmly and, when necessary,
apply the parking brake.
When shifting gears in extremely low temperatures
(-22°F/-30°C), there may be a short delay before the
shift is indicated in the display. Always confirm you
are in the correct gear before driving.

Shift Lever Operation
1Shift Lever OperationNOTICEWhen you change the shift lever from
(D to
(R and
vice versa, come to a complete stop and keep the
brake pedal depressed.
Operating the shift lever before the vehicle has come
to a complete standstill can damage the transmission.
Use the shift lever position indicator to check the
lever position before pulling away.
If the transmission indicator blinks when driving, in
any shift position, 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 shift
lever is in
( N, (P or
(R, the fuel supply may be cut
off even without the engine speed entering the
tachometer’s red zone.
It may not be possible to operate the shift lever if the
brake pedal is applied while the shift lever release
button is held down.
Depress the brake pedal first.

uuWhen Driving uShifting
Continued
Driving
Use the paddle shifters to change between 1st and 6th gears without removing your
hands from the steering wheel. The transmission will switch to the sequential shift
mode.■When the shift lever is in
(D
:
The vehicle will go into the sequential shift mode momentarily, and the gear position
indicator will come on.
Once you start traveling at a constant speed, the sequential shift mode will
automatically switch off, and the gear position indicator will go off.
Hold the
(+
paddle shifter for two seconds to return to normal drive.
■When the shift lever is in
(D
with SPORT mode:
The vehicle will go into the sequential shift mode, and the M (sequential shift)
indicator and gear position indicator will come on. At speeds of 6 mph (10 km/h) or
less, the vehicle automatically shifts down into 1st gear. If you do not operate the
paddle shifters while in 1st gear, the transmission automatically shifts up to 2nd
gear.
If the vehicle speed increases and the engine speed reaches near the tachometer’s
red zone, the transmission automatically shifts up to 6th.
You can cancel this mode by pressing SPORT button, or pulling the
(+
paddle
shifter for a few seconds. When the sequential shift mode is canceled, the sequential
shift mode indicator and shift indicator go off.

■Second gear lock mode
If you pull the
(+
paddle shifter while stopped or driving at 6 mph (10 km/h) or less,
the gear position will be locked in 2nd gear. This makes it easier to pull away on
slippery surfaces such as snow covered roads.
To cancel the 2nd gear lock mode, pull the
(-
paddle shifter.
■
Sequential Shift Mode Operation
1 Sequential Shift Mode Operation
Each paddle shift operation makes a single gear
change.
To change gears continuously, release the paddle
shifter before pulling it again for the next gear.
Recommended Shift Points
Use this table as a guideline for efficient fuel
economy and effective emission control.
If the gear posit ion indicator blinks when you try to
shift up or down, this means your vehicle speed is not
in its allowable gear range.
Slightly accelerate to shift up and decelerate to shift
down while the indicator is blinking.
In sport mode, to prioritize the engine performance
enhancement, the transmission may not allow for
shifting up while the engine speed is low. Shift Up Normal Acceleration
1st to 2nd
17 mph (28 km/h)
2nd to 3rd 27 mph (44 km/h)
