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.

Leaving your hood open and your
underhood lights on can drain your
battery.
If you need to keep the hood
open for an extended period
of time,
remove the Underhood Lights Fuse.
This 1O-amp fuse is located under the
hood on the left-hand marker light
assembly. See the
Index under Fuses &
Circuit Breakers.
Engine Oil
It's a good.idea to check pur engine oil
level every time you get fuel. In order to
get
an accurate reading, the vehicle
must be on level
ground.
If you have the LTl engine, the best
time
to check your engine oil is when
the
engine is warn. If the engine is
mnning, the engine oil won't drain back
into the pan.
Turn off the engine and
give the oil a few minutes to drain back
into the-oil
pan. If you don't, the oil
dipstick might not show the actual
level. If
you have a ZR-1, the best time to
chegk your engine oil is when
the
engine
is cold. If you run the engine, the
engine oil
won't drain back into the pan
fast enough.
Give the oil two hours to
drain
back into the oil pan. If you don't,
the oil dipstick might not
show the
actual level.

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.
