Warning (Continued)
.Put things in the rear area
of your vehicle. Try to
spread the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint

inside the vehicle, secure
it whenever you can.
Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km
(200 mi).
.New brake linings also need a
break- in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4000 rpm.
.Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
.Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
.Do not let the engine labor.
Never lug the engine. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
.After the first 500 miles, change
the engine oil on vehicles with
the LT1 engine and Z51
package, or the LT4 engine.
For the first 2 414 km (1,500 mi):
.Do not participate in track
events, sport driving schools,
or similar activities during the
first 2 414 km (1,500 mi).

10-24 Vehicle Care
{Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather. To remove the aero panel and
bracket:
1. Press up on the two indents at
the bottom and lift the aero
panel off the bracket.
2. Unscrew the two fasteners that

Vehicle Care 10-27
If coolant is needed, add the proper
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done.
1. When the cooling system,including the coolant surge tank
pressure cap and upper radiator
hose, is no longer hot, remove
the pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap slowly, and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL coolant
mixture until the level inside
stabilizes at the cold fill line on
the front of the surge tank. 4. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during this
procedure, 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 stabilizes at the
cold fill line on the coolant
surge tank.
5. Replace the pressure cap tightly. Check the level in the surge tank
when the system has cooled
down. If the coolant is not at the
proper level, repeat Steps 1−4,
then reinstall the pressure cap.
If the coolant is not at the proper
level when the system cools
down again, see the dealer.{Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See Engine
Coolant Temperature Gauge on
page 5-15. The vehicle may also
display a message on the Driver
Information Center (DIC). See
Engine Cooling System Messages
on page 5-37.
If the decision is made not to lift the
hood but to get service help right
away, see Roadside Assistance
Program on page 13-5.

Towing the Vehicle
{Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash
or hook to any suspension
components —including the
control arms, stabilizer bars, and
links —during towing and
recovery of a disabled vehicle,
or when securing the vehicle to a
flatbed car carrier. For towing and
recovery of a disabled vehicle,
use the proper hooks in the
correct locations on the front and
rear sub-frames. Use the proper
nylon strap harnesses around the
tires to secure them to the flatbed
car carrier.
Have the vehicle towed on a flatbed
car carrier. A wheel lift tow truck
could damage the vehicle. Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing”
following.
Recreational Vehicle
Towing
{Caution
Dolly towing or dinghy towing the
vehicle may cause damage
because of reduced ground
clearance. Always put the vehicle
on a flatbed truck or trailer.
The vehicle was neither designed
nor intended to be towed with any of
its wheels on the ground. If the
vehicle must be towed, see Towing
the Vehicle on page 10-83.
