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.

slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0161.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0189.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0189.
Manual Mode
Manual Paddle Shift
(Automatic Transmission)
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or
downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts.
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster
or the Head-Up Display (HUD),
if equipped. See Head-Up Display
(HUD) 0123.

Limited-Slip Differential
(Stingray without
Z51 Only)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard
axle most of the time, but when
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. For
vehicles with limited-slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
SeeCompetitive Driving Mode
0 203 andMaintenance Schedule
0 312.
Limited-Slip Differential
(ZR1, Z06, Grand Sport,
and Stingray with Z51)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With eLSD, the
vehicle has:
.
Enhanced high-speed control
. Improved traction through
corners, allowing more
acceleration
. More precise steering
. Increased vehicle agility
. Integration with StabiliTrak/ESC
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed.
See Competitive Driving Mode
0 203 andMaintenance Schedule
0 312.
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is disengaged if
the clutch is pressed for several
seconds.

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

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.
