9-30 Driving and Operating
The driver can select 1 (First) gear
for maximum acceleration from
a stop.
When using the Manual Paddle
Shift feature while in S (Sport Mode),
the current gear will be displayed in
the Driver Information (DIC), or the
Head-Up Display (HUD), if the
vehicle has either of these features.
If the vehicle has a Head-Up
Display (HUD), see Head-Up
Display (HUD) on page 5 32.
The Manual Paddle Shift system will
not allow either an up-shift or a
down-shift if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
If up-shifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When the transmission gear does
not respond to a shift change,
the DIC will show an X over the
gear display.
When a requested shift is denied
due to the speed restrictions shown,
the DIC will momentarily show an
X over the gear display and a
chime will sound.
If the vehicle has a HUD, and the
transmission gear does not respond
to a shift change, a chime will sound
and the HUD will momentarily show
an X over the gear display.
Manual Paddle Shift operation is
available for use with Cruise
Control. See Cruise Control on
page 9 45 Cruise Control for
more information.
The vehicle speeds required for
Manual Paddle Shift up-shifts
depend on several vehicle inputs,
which will vary the allowed up-shift
speed by a few km/h (mph).
