242 DRIVING AND OPERATING
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator light will display in the
instrument cluster.
When in Sport Mode, the vehicle will
shift automatically but may hold a
lower gear longer than it would in the
normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. SeeAutomatic
Transmission 0231. The steering,
including Active Rear Steer (if
equipped), will change to provide
more precise control.
If the vehicle is equipped with AWD,
Sport Mode sends more torque to the
rear wheels.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. Snow/Ice
Mode will use a different accelerator
pedal map in order to optimize
traction on slippery surfaces.
When selected, the Snow/Ice Mode
indicator light will display in the
instrument cluster.
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 0212.
If the vehicle is equipped with AWD,
Snow/Ice Mode will provide more
torque to the front wheels.
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).
If the Traction Control/electronic
stability control system begins to limit
wheel spin while using cruise control,
the cruise control automatically
disengages. See Traction Control/
Electronic Stability Control 0239. If a

{Warning
The brake wear warning sound
means that soon the brakes will not
work well. That could lead to a
crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the proper sequence to torque
specifications. See
Capacities and
Specifications 0404.
Brake pads should be replaced as
complete sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if
there is a rapid increase in pedal
travel. This could be a sign that brake
service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement parts.
If this is not done, the brakes may not
work properly. The braking
performance expected can change in
many other ways if the wrong
replacement brake parts are installed
or if parts are improperly installed.
Brake Fluid
The brake master cylinder reservoir is
filled with GM approved DOT 3 (for
gasoline only vehicles) or DOT 4 (for
PLUG-IN vehicles) brake fluid as
indicated on the reservoir cap. See
Engine Compartment Overview 0300
for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum
marks on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
. Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.

354 VEHICLE CARE
Use this rotation pattern if the
vehicle has different size tires on
the front and rear.
Different tire sizes should not be
rotated front to rear.Use this rotation pattern when
rotating tires of the same size
installed on all four wheel
positions.
If the vehicle has a compact spare
tire, do not include it in the tire
rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and Loading
Information label after the tires
have been rotated.
SeeTire Pressure 0347 and Vehicle
Load Limits 0213. Reset the Tire Pressure Monitor
System. See
Tire Pressure Monitor
Operation 0350.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque ”under Capacities and
Specifications 0404.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any rust
or dirt from places where the wheel
attaches to the vehicle. In an
emergency, a cloth or a paper towel
can be used; however, use a scraper
or wire brush later to remove all
rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or
rust build-up. Do not get grease

can be used; however, use a scraper
or wire brush later to remove all
rust or dirt.
12. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel.
13. Place the compact spare tire on the wheel-mounting surface.
{Warning
Never use oil or grease on bolts or
nuts because the nuts might come
loose. The vehicle's wheel could fall
off, causing a crash.
14. Reinstall the wheel nuts. Tighten each nut by hand until the wheel
is held against the hub.
15. Lower the vehicle by turning the jack handle counterclockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off.
The wheel nuts should be tightened
with a torque wrench to the proper
torque specification after replacing.
Follow the torque specification
supplied by the aftermarket
manufacturer when using accessory
locking wheel nuts. See Capacities
and Specifications 0404 for original
equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper sequence
and to the proper torque
specification. See Capacities and
Specifications 0404 for the wheel
nut torque specification.
16. Tighten the wheel nuts firmly in a crisscross sequence, as shown.
