9-26 Driving and Operating
With the shift lever in D (Drive) and
not in Permanent Tap Shift Mode,
the tap shift controls will activate a
temporary tap manual shift mode,
allowing the transmission to be
manually shifted. Automatic shifts
return after no manual shifts have
been done for seven to 10 seconds.
The Temporary Tap Shift Mode can
also be deactivated by holding the
right upshift control briefly.
While using Tap Shift, the vehicle
will have firmer, quicker shifting. You
can use this for sport driving or
when climbing or descending hills,
to stay in gear longer, or to
downshift for more power or engine
braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
revolutions per minute (rpm). The
transmission will not automatically
shift to the next lower gear if the
engine rpm is too high, nor to the
next higher gear when the maximum
engine rpm is reached.If shifting is prevented for any
reason, a SHIFT DENIED message
will be displayed in the instrument
cluster. See
Transmission
Messages on page 5-46.
When accelerating the vehicle from
a stop in snowy and icy conditions,
it is suggested to shift into second
gear. A higher gear allows the
vehicle to gain more traction on
slippery surfaces.Drive Systems

Driving and Operating 9-33
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. The
transmission will use 2 (Second)
gear instead of 1 (First) gear when
accelerating from a stop. The
vehicle will upshift normally when
the vehicle is moving. The
LF3 models will use a different
accelerator pedal map instead of
using 2 (Second) gear from stop.
The accelerator pedal will reduce
engine torque at small pedal inputs.
The transmission will also shift
differently to assist in maintaining
traction.
When selected, the Snow/Ice Mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
