Refer to the infotainment manual for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts064.
. Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even a
small amount of alcohol. You can
have a serious —or even fatal —
collision if you drive after drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control
a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time. Average driver reaction time is about
three-quarters of a second. In that
time, a vehicle moving at 100 km/h
(60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.
Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.

172 DRIVING AND OPERATING
Steering
Variable Effort Steering
The vehicle has a steering system that
varies the amount of effort required to
steer the vehicle in relation to the
speed of the vehicle.
The amount of steering effort required
is less at slower speeds to make the
vehicle more maneuverable and easier
to park. At faster speeds, the steering
effort increases to provide a sport-like
feel to the steering. This provides
maximum control and stability.
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort. See your dealer if there is a
problem.If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
Normal use of the power steering
assist should return when the system
cools down.
See your dealer if there is a problem.
Curve Tips
.
Take curves at a reasonable speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of the
curve before accelerating gently
into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may be
more effective than braking.
. Holding both sides of the steering
wheel allows you to turn
180 degrees without removing
a hand.
. Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:

186 DRIVING AND OPERATING
Stopping the Engine/OFF (No
Indicator Lights) :When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0190.
Automatic Transmission
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition will turn off.
Manual Transmission
If the vehicle is stationary, the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0190.
The vehicle may have an electric
steering column lock. The lock is
activated when the ignition is turned
off and either front door is opened.
A sound may be heard as the lock actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location. 3. Come to a complete stop. Shift to
P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Parking Brake (Electric) 0201
or Parking Brake (Manual) 0203.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice within five seconds.
ACC/ACCESSORY (Amber Indicator
Light) : This mode allows you to use
some electrical accessories when the
engine is off.

DRIVING AND OPERATING 197
Tap Shift
If equipped, the tap shift controls are
on the back of the steering wheel.
To use DSC using the tap shift
controls:1. Move the shift lever to the left from D (Drive) to M (Manual
Mode). The transmission will be
in Manual Mode and will hold
the current gear.
2. Pull the control toward you to shift. Pull the left control to
(−) downshift, and the right control to (+) upshift. To shift to
the lowest available gear, press
and hold the left control (−).
3. To cancel DSC, move the shift lever back to D (Drive).
Tap Shift Mode can also be used
temporarily while driving in D (Drive).
Pull either the (+) upshift or
(−) downshift control.
To cancel Tap Shift Mode, hold
the (+) upshift control for two seconds.
If no action is taken, the vehicle
returns to automatic shifting after a
brief period of driving at a steady
speed, or when the vehicle comes to
a stop.
While using the DSC feature, the
vehicle will have firmer, quicker
shifting. This can be used for sport
driving, climbing or descending hills,
staying in gear longer, downshifting
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). The transmission
will not automatically shift to the next
higher gear if the engine rpm is
too high.
If shifting is prevented for any reason,
a DIC message will appear.
When accelerating the vehicle from a
stop in snowy and icy conditions, it is
suggested to shift into second gear,
or third gear as available. A higher
gear allows the vehicle to gain more
traction on slippery surfaces. See
Driver Mode Control
0205.

DRIVING AND OPERATING 199
R (Reverse) :To back up, press down
the clutch pedal, completely stop the
vehicle, and shift into R (Reverse). On
ATS models, apply additional pressure
to get the lever past 1 (First) and
2 (Second) into R (Reverse). Let up on
the clutch pedal slowly while pressing
the accelerator pedal.
{Warning
If you skip a gear when
downshifting, you could lose
control of the vehicle. You could
injure yourself or others. Do not
shift down more than one gear at a
time when downshifting.
Caution
When downshifting, if more than
one gear is skipped, or the engine is
racing when the clutch pedal is
released, the engine, clutch,
driveshaft or transmission could be
damaged.
No Lift-Shift
On ATS-V vehicles equipped with a
manual transmission, the vehicle can
be shifted up a gear when the
accelerator pedal is pressed to the
floor without being released. This
allows for less power interruption and
will improve acceleration times. This
feature is available in all vehicle
modes and is only active when the
engine speed is greater than 2500 rpm.
Active Rev Match
ATS-V vehicles equipped with a
manual transmission have Active Rev
Match (ARM). ARM aids in smoother
shifting by matching the engine speed
to the next selected gear. By
monitoring shift lever and clutch
operation, ARM adjusts engine speed
to match a calibrated value based on
gear selection. On upshifts and
downshifts, engine speed will be
increased and decreased to match
vehicle road speed and transmission
gear position. ARM is maintained
while the clutch pedal is pressed, but
will deactivate if the shift lever is left
in the Neutral position.
The system is activated and
deactivated by pressing either of the
paddles on the steering wheel. The
system must be activated with each
new ignition cycle.
A gear indicator in the instrument
cluster displays the current gear
selected. ARM is also shown in the
Performance View of the HUD:
. When ARM is activated, the gear
number is amber.
. When ARM is deactivated, the
gear number is white.

package, available features, and mode
selected, the suspension, steering, and
powertrain will change settings to
achieve the desired mode
characteristics. If the vehicle is
equipped with Magnetic Ride Control,
selecting the various Driver Modes
adjusts the ride of the vehicle to
enhance the ride performance for the
road conditions and the
selected mode.
The Driver Mode Control has three or
four modes: Tour, Sport, Snow/Ice,
and Track (V-Series Only). Snow/Ice
mode is only available on automatic
transmission vehicles. Press and
release the MODE button (ATS) or
press the
yorzbutton (ATS-V) on
the center console to activate the
mode menu in the cluster. The first
press of the button will show the
current mode. Subsequent presses will
scroll though the available modes. The
Tour and Sport modes will feel similar
on a smooth road. Select a new
setting whenever driving conditions
change.
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport mode
indicator will display in the Driver
Information Center (DIC).
When in Sport or Track 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. See
Automatic Transmission 0194. The
steering will change to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
will change to provide better
cornering performance.
Competitive Driving Mode can be
accessed through this mode.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions.
Snow/Ice mode will use a different
accelerator pedal map to optimize
traction on a slippery surface. 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
vehicle becomes stuck, see If the
Vehicle Is Stuck 0181.

VEHICLE CARE 321
Caution
Chrome wheels and chrome wheel
trim may be damaged if the vehicle
is not washed after driving on roads
that have been sprayed with
magnesium chloride or calcium
chloride. These are used on roads
for conditions such as dust and ice.
Always wash the chrome with soap
and water after exposure.
Caution
To avoid surface damage on wheels
and wheel trim, do not use strong
soaps, chemicals, abrasive polishes,
cleaners, or brushes. Use only GM
approved cleaners. Do not drive the
vehicle through an automatic car
wash that uses silicone carbide tire/
wheel cleaning brushes. Damage
could occur and the repairs would
not be covered by the vehicle
warranty.
Brake System
Visually inspect brake lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake
pads for wear and rotors for surface
condition. Inspect drum brake linings/
shoes for wear or cracks. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinge, unless the
components are plastic. Applying
silicone grease on weatherstrips with aclean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
At least twice a year, spring and fall,
use plain water to flush any corrosive
materials from the underbody. Take
care to thoroughly clean any areas
where mud and other debris can
collect.
Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced
Sheet Metal Damage
If the vehicle is damaged and requires
sheet metal repair or replacement,
make sure the body repair shop
applies anti-corrosion material to
parts repaired or replaced to restore
corrosion protection.
