Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0265.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line. .
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, crash).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0198.

special procedure when changing
the engine oil and filter. SeeEngine
Oil 0232.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may not indicate that an oil
change is necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi) since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
Dry Sump Engine Break-In Oil
Change
If equipped with a dry sump engine,
the initial oil and filter change must
be performed at 800 km/500 mi.
Follow the engine oil life system for
every oil change thereafter.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Scroll through the DIC Info Pages menu until the
REMAINING OIL LIFE
percentage is displayed. See
Driver Information Center (DIC)
0121.
2. Press and hold SEL on the DIC while the Oil Life display is
active. The oil life will change
to 100%. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12032182) - 2019 - crc - 5/8/18
Vehicle Care 239
service manual. To purchase a
service manual, seePublication
Ordering Information 0339.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the correct
automatic transmission fluid. See
Recommended Fluids and
Lubricants 0321.
Change the fluid and filter at the
proper intervals. See Maintenance
Schedule 0312. Be sure to use the
correct fluid. See Recommended
Fluids and Lubricants 0321.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the dealer and have it repaired as soon
as possible. See
Recommended
Fluids and Lubricants 0321 for the
proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
The fluid will darken over time. See
Maintenance Schedule 0312 for
when to replace the fluid.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview
0 225 for reservoir location.
Refer to Recommended Fluids and
Lubricants 0321 for the proper fluid
to use. The fluid requires changing.
See Maintenance Schedule 0312.
How to Check and Add Fluid
Visually check the clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The hydraulic
clutch fluid system should be closed
and sealed.
Do not remove the cap to check the
fluid level or to top off the fluid level.
Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
Engine Air Cleaner/Filter
See Engine Compartment Overview
0 225 for the location of the engine
air cleaner/filter.

250 Vehicle Care
lightly applied. Brake linings should
always be replaced as complete
axle sets.
Brake Rotor Wear
ZR1, Z06, and Grand Sport models
may have ceramic brake rotors.
Rotors should be visually inspected
whenever the brake pads are
replaced. Rotors also need to be
weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear-out
mass printed on then rotor. The
rotor can be reused if the weight of
the rotor is above the mass limit.
Rotor inspection and weighing
methods can be found in the service
manual.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or parts are improperly
installed.
Cold Weather Brake Operation
High performance brake
components may bind and clunk
when moving the vehicle. This may
be noticeable after parking when the
brakes have been wet, such as
when driving in the rain or after a
car wash. This is normal for brakes
with high friction pads and does not
affect the operation of the brakes.
Apply the brakes several times until
the binding or clunking stops. Drive
the vehicle and apply the brakes
several times if it is washed before
long-term storage.
Brake Fluid
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 4 brake fluid as indicated on
the reservoir cap. SeeEngine
Compartment Overview 0225 for
the location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake
applied if equipped with a manual
transmission. On a level surface,
the brake fluid level should be
between the minimum and
maximum marks on the brake fluid
reservoir.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12032182) - 2019 - crc - 5/8/18
Vehicle Care 253
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
The fluid level should be at or within
13 mm (0.5 in) of the bottom of the
fill plug hole threads. If it is at this
level, no additional fluid is needed.
If the fluid level is below 13 mm
(0.5 in), add fluid until it is above
this level.
What to Use
To add lubricant when the level is
low or to completely refill after
draining, seeRecommended Fluids
and Lubricants 0321. Then fill to
within 13 mm (0.5 in) of the bottom
of the fill plug hole threads with the
required lubricant.
Starter Switch Check
{Warning
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular brake.
See Electric Parking Brake
0 195. Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. For automatic transmission vehicles, try to start the engine
in each gear. The vehicle
should start only in P (Park) or
N (Neutral). If the vehicle starts
in any other position, contact
your dealer for service.
For manual transmission
vehicles, put the shift lever in
Neutral, push the clutch pedal
down halfway, and try to start
the engine. The vehicle should
start only when the clutch
pedal is pushed down all the
way to the floor. If the vehicle
starts when the clutch pedal is
not pushed all the way down,
contact your dealer for service.
