Driving through Deep Standing Water
NOTICE:
If you drive too quickly through deep
puddles or standing water, water can
come in through your engine’s air
intake and badly damage your
engine. If you can’t avoid deep
puddles or standing water, drive
through them very slowly.
Rough Idling
If you notice rough idling or surging,
especially after long periods of idling or
during slow city driving, the oxygen
sensors may be clogged. If this happens,
follow these steps to clear the oxygen
sensors:
1. Set the parking brake.
2. Shift an automatic transmission to “P”
(Park) or a manual transmission to
“N’ (Neutral).

Engine Coolant Heater (Engine
Block Heater)
(LTI ENGINE, CANADA)
In very cold weather, 0 “F (- 18 “C) or
colder, the engine coolant heater can help.
You’ll get easier starting and better fuel
economy during engine warm-up.
Usually, the coolant heater should be
plugged in a minimum of four hours prior
to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
3. Plug it into a normal, grounded
1 10-volt outlet.
I NOTICE:
After you’ve used the coolant heater,
be sure to store the cord as it was
before to keep it away from moving
engine parts. If you don’t, it could be
damaged.

Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant
heater plugged in? The answer depends
on the weather, the kind of
oil you have,
and some other things. Instead of trying
to list everything here, we ask that you
contact your Chevrolet dealer in the area
where you’ll be parking your vehicle. The
dealer can give you the best advice for
that particular area.

Automatic Transmission
There are several different positions for
your shift lever.
P (Park)
This locks your rear wheels. It’s the best
position to use when you start your
engine because your vehicle can’t move
easily. Ensure the shift
lever is fully in
“P”
(Park) range before starting the engine.
Your Corvette has a brake-transmission
shift interlock. You have to fully apply
your regular brakes before you can shift
from “P” (Park) when the ignition key is
in the “Run” position. If you cannot shift
out of
“P” (Park), ease pressure on the
shift lever
- push the shift lever all the

the system will lower the inside
temperature up to
5°F (3°C) below
the setting on the display.
Outside Temperature: This sensor is
on the right side of the upper radiator
support in the grille opening. This is
what you usually see on the display.
If the outside temperature goes up,
the displayed temperature will not
change until:
Vehicle speed is above 25 mph
(40 kmh) for at least 3 minutes,
or
Vehicle speed is above 45 mph
(72
km/h) for 1 1/2 minutes.

Downloaded from www.Manualslib.com manuals search engine This delay helps prevent a false reading.
If vehicle speed remains above
25 mph
(40 kmh) or the temperature goes down,
the display is updated immediately.
If your vehicle has been
off for more than
three hours, the current outside
temperature will be stored
in the system
