Use the paddle shifters to change between 1st and 10th gears without releasing
your hands from the steering wheel. The transmission will switch to the sequential
mode.

The vehicle will go into the sequential mode momentarily, and the sequential mode
gear selection indicator will come on.

When the vehicle goes into the sequential mode by

gear is available, the transmission properly selects single or double gear change.

Once you start traveling at a constant speed, the sequential mode will automatically
switch off, and the sequential mode gear selection indicator will go off.

Sequential 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.

If the sequential mode gear selection 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.

The transmission is in

(

S

and

Sport+

mode, to

prioritize the engine performance enhancement, the
transmission may not allow for shifting up while the
engine speed is low.

It does so by regulating engine output and selectively applying the brakes.

You may also notice some noise from the
hydraulic brake system. You will also see the
indicator blink.

system. While this may not interfere with normal
driving, have your vehicle checked by a dealer
immediately.

and does not control the entire braking system. You
still need to drive and corner at speeds appropriate

function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA

Immediately after freeing your vehicle, be sure to
switch VSA
