Use the paddle shifters to change between 1st and 8th 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 goes into sequential sift mode and the M (sequential shift) indicator
comes on. At speeds of 2 mph (4 km/h) or less, the vehicle automatically shifts down
into 1st gear.
If you are in 1st through 6th gears and do not operate the paddle shifters as engine
speed increases approaches the tachometer red zone, the transmission
automatically shifts up to the next gear.
You can cancel Sport+ mode by either:
• Pressing the IDS button.
• Or holding the
(+
paddle shifter for two seconds.
When the mode is canceled the sequential mode and sequential mode gear

■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 position 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. Shift Up Normal Acceleration
