If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method
known as “rocking” can
rou must use caution. I help you get out when you’re stuck, but
CAUT/UN I
A: If :you let.your :tires. spin -at
high speed.when the ASR
, . ‘OFE warning light is on, or when
“the SERVICE ASR warning light is
‘on, your tires can explode and you
or others could be injured. And,
spinning your tires with either of
these lights on can cause the
automatic transmission
or other
parts of the vehicle to overheat.
That could cause an engine
compartment fire or other damage.
When you’re stuck, spin the wheels
as little as possible. Don’t spin the
wheels above 35 mph (56 M) as
shown on the speedometer.
Rocking Your Vehicle to Get It Out:
First, turn your steering wheel left and
right. That will clear the area around
your front wheels. You should turn your
ASR system off. Then, shift back and
forth between R (Reverse) and a
forward gear--or if you have a manual
transmission, between 1 or 2 and
R (Reverse)-spinning the wheels as
little as possible. Release the accelerator
pedal while
you shift, and press lightly
on the accelerator pedal when the
transmission is in gear.
If that doesn’t
get
you out after a few tries, you may
need to be towed out.
If you do need to
be towed
out, see the Index under
Towing Your Corvette and Acceleration
Slip Regulation (ASR) System.

should.
What to Use:
Use a mixture of one-half clean wafer
(preferably distilled) and one-half
antifreeze that
meets “GM Specification
1825-M,” which won’t damage
aluminum parts. You can also use a
recycled coolant conforming to GM
Specification 1825-M with a complete
coolant
flush and refill. If you have the
LTl engine, use GM Engine Coolant
Supplement (sealer)
with any complete
coolant change.
If you use these, you
don’t need to add anything else.

WETen your brake fluid falls to a.low
level,
your brake warning light,
SERVICE ABS light and SERVICE
ASR light will come on. The- anti-lock
brake and .acceleration
slip regulation
systems are disabled when your brake
flu.id falls to
it low level. See thedndex
under
Brake System Warning Light;
To Add Brake Fluid:
Lift the cap and pour in fluid to the
MAX mark on the master cylinder. Do
not oveffiI1.
&%at to Add:
When you do need brake fluid, use-
)nly
DOT-3 brake fluid-such as
lelcrr Supreme 1P (GM Part No.
.052535). Use new brake fluid from a
'eded. container only.
NOTlCE
Replacing Brake System Parts
The braking system on a modern
vehicle is
complex. Its many parts have
to be
of top quality -and work well
together if the vehicle is to haye really
good braking. Vehicles we design and
test have top-quality GM brake-parts in
the&, as
your Corvette does when it is
new. When you replace parts of your
braking 'system-for example, when
your brakelinings wear down and you
have to have new ones put in-be sure
you get new genuine GM replacement
parts. If.you don't, your brakes may no
longer work properly. For example, if
someone.puts
in b.r&e linings that are
wrong for your vehicle, .the balance
between your
front and rear brakes can
change, for the worse. The braking
performance
you've come to expect can
change in many other ways if.-someone
puts
in the wrong replacement brake
parts.

Inspection
WHAT SHOULD BE DOME
Inspect. the front and rear susp-ension and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses. for proper
hookup,
bindmg-, leaks, cracks, chafing, etc.
Inspect the tires for uneven wear or damage. If there is irregular or premature wear, check the
wheel alignment. Inspect for damaged wheels.
Inspect the complete exhaust system. Inspect the
body neat the exhaust system. Look for broken,
damaged, missing or out-of-position parts as well as open seams, holes, loose connections, or
other conditions which could cause a heat buildup in the floor pan or could let exhaust fumes
into the- vehicle.
See the Index under Engine Exhaust.
Check:the gear lubricant leve1.h the rear axle and add if needed. See the Index: under Rear Axle.
A fluid loss in this system;may indicate a problem. Check the system and repair it if needed.
Inspect the complete system. Inspect brake lines and
hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect
-other brake parts, .hcluding calipers, parking brake, etc. Check parking brake adju\
stment. You
may need
to have your brakes inspected more often if your driving habits or conditions result in
frequent braking.
NOTE:. A low brake fluid level can indicate worn disc brake pads which may need to be
serviced.
Also, if 'the brake system warning light stays on or comes on, something may be wrong
with .the brake system. See the Index under Brake System Warning Light. 'If your anti-lock brake
systemwarning light stays on, comes on or flashes, something may be wrong with the anti-lock
brake system. See the Index under Anti-Lock Brake System Warning Light.
