3. Pull the control toward you to shift. Pullthe left control to downshift, and the
right control to upshift. To shift to the
lowest available gear, pull and hold the
left control.
To exit Permanent Tap Shift Mode: 1. To exit M (Manual Mode) and return to D (Drive), pull back on the shift lever.
The D in the shift pattern will illuminate
in red, and the M will switch to white.
2. After releasing the shift lever, it will return to the center position.
M (Manual Mode) can be exited to return to
D (Drive) at any speed by pulling the lever
rearward from the center position. It is not
necessary to stop the vehicle or shift to
N (Neutral) or P (Park) prior to shifting back
to D (Drive).
Temporary Tap Manual Shift Mode
To enter Temporary Tap Shift Mode: 1. With the transmission 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. 2. To deactivate, hold the right control
briefly. Automatic shifts return after no
manual shifts have been done for seven
to 10 seconds.
While using Tap Shift, the vehicle will have
firmer, quicker shifting. This can be used 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 shifting
into gears appropriate for the vehicle speed
and engine revolutions per minute (rpm).
If shifting is prevented for any reason, the
M or D will flash in the instrument cluster.
The transmission will not automatically shift
to the next higher gear if the engine rpm is
too high. It will only automatically shift to
the next lower gear if the engine rpm is
much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate in
All-Wheel Drive (AWD) Mode. When the
AWD feature is active, the system transfers
engine power, if required, to all four wheels.
The system is fully automatic and adjusts to road conditions for improved traction and
control. In FWD Mode engine power is
transferred to the front wheels only, and
the AWD feature is off.
The AWD feature is automatically activated
when certain modes are selected using the
Driver Mode Control switch. When an AWD
mode change is requested the light will
flash briefly while the system is engaging
and the AWD light will be displayed when
the system is active. When a non-AWD
Mode is selected, the light will flash briefly
while the system disengages and a 2WD
light will be displayed when the AWD
system is off. See
Driver Mode Control
0 190.
When a compact spare tire is installed on an
AWD vehicle, the system will automatically
detect the compact spare and reduce AWD
performance to protect the system. 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 0315.

affected vehicle systems are dependent on
vehicle trim level, region, and optional
features.
If the vehicle is in Tour or AWD Mode, it
will stay in that mode through future
ignition cycles. If the vehicle is in any other
mode, it will return to Tour Mode when the
vehicle is restarted. When a mode is
selected, an indicator will come on in the
instrument cluster and stay on.
Driver Mode Control Switch
To activate each mode, press the MODE
button on the center console.
Tour Mode : Use for normal city and
highway driving to provide a smooth ride.
This setting provides balance between comfort and handling. This is the standard/
default mode. There is no persistent
indicator in the instrument cluster for
this mode.
AWD Mode :
AWD Mode provides torque to
all four wheels. Select AWD to improve
traction and control on slippery road
surfaces, such as gravel, sand, wet
pavement, snow, and ice. For more
information on AWD Mode, see All-Wheel
Drive 0186.
Sport Mode : Use where road conditions or
personal preference demand a more
controlled response. Sport Mode improves
vehicle handling and acceleration on dry
pavement. When active, Sport Mode
modifies steering efforts, transmission
shifting, and AWD torque, if equipped.
The Performance Algorithm Liftfoot (PAL)
feature is enabled in Sport Mode. PAL allows
the transmission to hold the current gear
after a quick release of a heavily applied
accelerator pedal. This provides greater
engine braking and enhanced vehicle control.
When PAL is activated, there may be an
additional gear symbol that appears in the
instrument cluster display. See Performance
Shifting Light 0105. Off-Road Mode :
Use this mode for off-road
recreational driving. When active, Off–Road
Mode should be used to improve driving at
moderate speeds, on grass, gravel, dirt,
unpaved roads, or snow-covered roads. The
accelerator pedal is tuned for off-road use.
This mode modifies pedal mapping, AWD,
ESC, and TCS Performance.
Snow/Ice Mode : Snow/Ice Mode improves
vehicle acceleration on snow and ice covered
roads. When active, Snow/Ice Mode will
adjust acceleration to optimize traction on
slippery surfaces. This can compromise the
acceleration on dry asphalt. This feature is
not intended for use when the vehicle is
stuck in sand, mud, ice, snow, or gravel.
If the vehicle becomes stuck, see If the
Vehicle Is Stuck 0169.
qMy Mode : Use this mode to
personalize everyday driving. This mode
allows the driver to configure the vehicle
subsystem settings to their driving
preferences. My mode remains active across
on/off cycles.
Through the infotainment display, the
following vehicle subsystems may be
available for customization in this mode:
Acceleration Feel : Relaxed, Tour, Sport

replaced at the same time. If proper
rotation and maintenance have been
done, all four tires should wear out at
about the same time. However, if it is
necessary to replace only one axle set
of worn tires, place the new tires on
the rear axle. SeeTire Rotation0297.
{Warning
Tires could explode during improper
service. Attempting to mount or
dismount a tire could cause injury or
death. Only your dealer or authorized
tire service center should mount or
dismount the tires.
{Warning
Mixing tires of different sizes (other
than those originally installed on the
vehicle), brands, tread patterns,
or types may cause loss of vehicle
control, resulting in a crash or other
vehicle damage. Use the correct size,
brand, and type of tire on all wheels.
{Warning
Using bias-ply tires on the vehicle
may cause the wheel rim flanges to
develop cracks after many miles of
driving. A tire and/or wheel could fail
suddenly and cause a crash. Use only
radial-ply tires with the wheels on
the vehicle.
Winter tires with the same speed rating
as the original equipment tires may not
be available for H, V, W, Y and ZR
speed rated tires. Never exceed the
winter tires’ maximum speed capability
when using winter tires with a lower
speed rating.
If the vehicle tires must be replaced
with a tire that does not have a TPC
Spec number, make sure they are the
same size, load range, speed rating, and
construction (radial) as the original
tires.
The Tire and Loading Information label
indicates the original equipment tires
on the vehicle. See Vehicle Load Limits
0 170.Different Size Tires and Wheels
If wheels or tires are installed that are a
different size than the original equipment
wheels and tires, vehicle performance,
including its braking, ride and handling
characteristics, stability, and resistance to
rollover may be affected. If the vehicle has
electronic systems such as antilock brakes,
rollover airbags, traction control, electronic
stability control, or All-Wheel Drive, the
performance of these systems can also be
affected.
{Warning
If different sized wheels are used, there
may not be an acceptable level of
performance and safety if tires not
recommended for those wheels are
selected. This increases the chance of a
crash and serious injury. Only use GM
specific wheel and tire systems developed
for the vehicle, and have them properly
installed by a GM certified technician.
