Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in every
Canadian province says children up to some age must
be restrained while in a vehicle.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children
and infants. Neither the vehicle’s safety belt system
nor its airbag system is designed for them. Every time
infants and young children ride in vehicles, they
should have the protection provided by appropriate
child restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.

3. Do not race the engine immediately after starting it.
Operate the engine and transmission gently until
the oil warms up and lubricates all moving parts.
4. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again to let
the cranking motor cool down.
If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
while cranking for up to 15 seconds maximum.
Notice:Cranking the engine for long periods of
time, by pressing the START button immediately
after cranking has ended, can overheat and damage
the cranking motor, and drain the battery. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down.When the engine starts, let go of the accelerator.
If the vehicle starts brie y but then stops again,
do the same thing. This clears the extra gasoline
from the engine.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine and
protects components. Once cranking has been initiated,
the engine continues cranking for a few seconds or until
the vehicle starts. If the engine does not start, cranking
automatically stops after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this system
also prevents cranking if the engine is already running.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.

Lane Departure Warning (LDW)
If the vehicle has the LDW system. Read this entire
section before using the system.
{CAUTION:
The Lane Departure Warning (LDW) system does
not steer the vehicle and is only an aid to help you
stay in your driving lane. The LDW system may not:
Provide you with enough time to avoid a lane
change collision.
Be loud enough for you to hear the warning
beeps.
Work properly under bad weather conditions or
if the windshield is not kept clean.
Detect lane markings and will not detect road
edges.
Warn you that your vehicle is crossing a lane
marking if the system does not detect the lane
marking.
CAUTION: (Continued)
CAUTION: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle position
within the lane, vehicle damage, injury, or death
could occur. Even with LDW, always keep your
attention on the road and maintain proper vehicle
position within the lane. Always keep the windshield
clean and do not use LDW in bad weather
conditions.
When the vehicle crosses a detected lane marking, the
LDW symbol will ash and you will hear three beeps.
LDW will not warn you if the turn signal is on or if
the vehicle makes a sharp maneuver. Before making
a lane change, check the vehicle’s mirrors, glance over
your shoulder for vehicles and hazards, and turn on
the turn signal before changing lanes.

The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar

OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility

cannot be heard. If the light next to the OnStar buttons
is red, the system may not be functioning properly.
Press the OnStar button and request a vehicle
diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press the OnStar
button to con rm that the OnStar equipment is active.
