9-30 Driving and Operating
D (Drive):This position is for
normal driving. It provides the
best fuel economy. If more power
is needed for passing, and the
vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Notice: If the vehicle seems to
accelerate slowly or not shift
gears when you go faster, and
you continue to drive the vehicle
that way, you could damage the
transmission. Have the vehicle
serviced right away. You can
drive in L (Low) when you are
driving less than 56 km/h (35 mph)
and D (Drive) for higher speeds
until then.
Manual Mode: This position is
shown on the shifter as a +/−.
It allows the driver to select the
gears appropriate for current driving
conditions. See Manual Mode on
page 9‑30 for more information.
Manual Mode
Driver Shift Control (DSC)
Notice:If you drive the vehicle
at a high rpm without upshifting
while using Driver Shift Control
(DSC), you could damage the
vehicle. Always upshift when
necessary while using DSC.
Driver Shift Control (DSC)
allows you to shift an automatic
transmission similar to a manual
transmission. To use the DSC
feature:
With Selective Ride Control
1. Move the shift lever to the left from D (Drive).
The vehicle will be in Sport
Mode. The gear indicator in
the DIC will still display a D for
Drive, and the SPORT MODE
ON message will be displayed
momentarily. See Driver
Information Center (DIC) on
page 5‑25. When you are in
Sport Mode, the vehicle will still shift automatically, but
chassis tuning is modified.
See
Selective Ride Control on
page 9‑38. If you move the
shift lever forward or rearward,
the transmission will enter
Manual Mode, and the DIC
gear indicator will change to
an M followed by a number
representing the gear the
vehicle is currently in.
2. In Manual Mode, press the shift lever forward to upshift
or rearward to downshift.
Without Selective Ride Control
1. Move the shift lever to the left from D (Drive).
The transmission will enter
Manual Mode. The DIC gear
indicator will change to an
M followed by a number
representing the gear the
vehicle is currently in.
2. In Manual Mode, press the shift lever forward to upshift
or rearward to downshift.

Driving and Operating 9-31
Uplevel Display Shown,Base Model Similar
The display on the instrument panel
cluster will show which gear the
vehicle is in. The number indicates
the requested gear range when
moving the shift lever forward or
rearward. 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.
While in the DSC mode, the
transmission will automatically
downshift when the vehicle comes
to a stop. This will allow for more
power during take-off.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear allows you to
gain more traction on slippery
surfaces.
Drive Systems
All-Wheel Drive
Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare
tire on an AWD vehicle, the
system automatically detects
the compact spare and disables
AWD. To restore AWD operation
and prevent excessive wear on
the system, replace the compact
spare with a full-size tire as soon as
possible. See
Compact Spare Tire
on page 10‑85 for more information.

provides consumers with
ratings for a tire's traction,
temperature, and treadwear.
Ratings are determined by
tire manufacturers using
government testing procedures.
The ratings are molded into
the sidewall of the tire.
