168 Driving and Operating
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. 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, accident).
. 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 0192.
. The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
See Antilock Brake System
(ABS) 0189.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise

Driving and Operating 183
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D : This position is for normal
driving. If more power is needed for
passing, press the accelerator
pedal down. Downshifting the transmission in
slippery road conditions could result
in skidding. See
“Skidding”under
Loss of Control 0156.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0183.
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 0183.
Manual Mode
Manual Paddle Shift
(Automatic Transmision)
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.

Driving and Operating 187
The vehicle can be safely shifted
into R (Reverse) while the vehicle is
moving less than 5 km/h (3 mph).
If the vehicle is going faster than
that, R (Reverse) is locked out.
Caution
A transmission hot message may
display if the manual transmission
fluid is too hot. Driving at high
speed under this condition can
damage the vehicle. Drive at a
slower speed, or stop and idle the
engine to cool the manual
transmission fluid. The message
clears when the vehicle has
slowed and the transmission fluid
has cooled sufficiently.
Shift Speeds
Use the following shift speeds,
shown in km/h (mph), for the best
fuel economy.1 to 4 27 (17)
4 to 5 40 (25)
5 to 6 64 (40)
6 to 7 72 (45)
Caution
When shifting gears, do not move
the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.
1–4 Shift Message
When the DIC displays this
message, the vehicle can only be
shifted from 1 (First) to 4 (Fourth).
Downshifting
Do not downshift into the gear at a
speed greater than shown:1 (First) 72 km/h (45 mph)
2 (Second) 107 km/h (67 mph) 3 (Third) 160 km/h (100 mph)
4 (Fourth) 233 km/h (145 mph)
Caution
When downshifting, if more than
one gear is skipped, or the engine
is racing when the clutch pedal is
released, the engine, clutch,
driveshaft or transmission could
be damaged.
If the engine speed drops below
900 rpm, or if the engine is not
running smoothly, downshift to the
next lower gear. It may be
necessary to downshift two or more
gears.

track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.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.
