150 Driving and Operating
2. Press the + (plus) end of the button onthe side of the shift lever to upshift,
or press the −(minus) end of the button
to downshift.
The instrument cluster will change from the
currently displayed message to the letter
“M,” for Manual position, and a number
indicating the requested gear.
While using the DSC feature, the
transmission will have firmer shifting and
sportier performance. This can be used for
sport driving or when climbing 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 allow shifting to
the next higher gear if the vehicle speed
or engine rpm is too low.
.The transmission will not allow shifting to
the next lower gear if the vehicle speed
or engine rpm is too high. Automatic Transmission Adaptation Feature
While the vehicle is being driven and gear
shifting takes place, the transmission will
learn and adapt. This increases durability
and maintains the best shift quality of the
life of the vehicle.
During vehicle break-in (initial driving), it is
normal to experience some shift bumps.
Shift quality will improve with the normal
gear shifting as the transmission learns and
adapts.
Drive Systems
All-Wheel Drive
If equipped, this feature transfers engine
power, as required, to all four wheels. It is
fully automatic, and adjusts itself as needed
for road conditions.
When using a compact spare tire on an
All-Wheel Drive (AWD) vehicle, the system
automatically detects the compact spare and
disables AWD to protect the system.
A Driver Information Center (DIC) message
will display on the instrument cluster. See
Vehicle Messages
092. 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
0220.
AWD will be disabled and the message will
display if there is excessive wheel spin.
When the system cools down, AWD will be
restored.
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 086.

152 Driving and Operating
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 129.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily prevents the
vehicle from rolling in an unintended
direction during the transition from brake
pedal release to accelerator pedal apply. The
brakes release when the accelerator pedal is
applied or automatically release after a few
seconds. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle may have a Traction Control
System (TCS) and StabiliTrak/Electronic
Stability Control (ESC), an electronic stability
control system. These systems help limit
wheel slip and assist the driver in
maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path. If cruise control is being used and traction
control or StabiliTrak/ESC begins to limit
wheel spin, cruise control will disengage.
Cruise control may be turned back on when
road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
If the
Vehicle Is Stuck 0133 and “Turning the
Systems Off and On” later in this section.
The indicator light for both systems is in the
instrument cluster. This light will:
.Flash when TCS is limiting wheel spin.
.Flash when StabiliTrak/ESC is activated.

3. Fill the coolant surge tank with theproper mixture to the indicated
level mark.
4. With the coolant surge tank pressure cap off, start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If the
level is lower, add more of the proper
mixture to the coolant surge tank until
the level reaches the indicated
level mark.
5. Replace the pressure cap tightly. 6. Verify coolant level after the engine is
shut off and the coolant is cold.
If necessary, repeat coolant fill procedure
Steps 1–6.
If the coolant still is not at the proper level
