Transmission
Manual Paddle Shift
(Automatic Transmission)
The Manual Paddle Shift system
can be used in D (Drive) or
M (Manual Mode). The system is
activated by pushing the left paddle
to downshift and right paddle to
upshift. The current gear will be
displayed in the instrument cluster,
or the Head-Up Display (HUD),
if equipped.The Manual Paddle Shift system will
not allow either an upshift or a
downshift, if the vehicle speed is too
fast or too slow, nor will it allow a
start from 4 (Fourth) or higher gear.
See
Manual Mode on page 9-28.
Active Rev Match (Manual
Transmission)
Vehicles equipped with a manual
transmission have Active Rev Match
(ARM). ARM aids in smoother
shifting by matching the engine
speed to the next selected gear.
The system is normally off. It is
activated and deactivated by
pressing either of the paddles
marked REV MATCH on the
steering wheel. See Active Rev
Match on page 9-33.
1–4 Shift Message (Manual
Transmission)
On vehicles with a manual
transmission, when this DIC
message is displayed, the transmission can only shift from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second).
For more information about shifting
for the best fuel economy, see
Manual Transmission on page 9-31.

i
and the StabiliTrak OFF Lightg
illuminate in the instrument
cluster.
.Press and release the TCS/

See Traction Control/Electronic
Stability Control on page 9-37.
The vehicle has Driver Mode
Control and may have Competitive
Driving Mode. See Driver Mode
Control on page 9-39 and
Competitive Driving Mode on
page 9-43.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-14.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure. The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-57.Performance Vehicle
Features
Checking Engine Oil
Your vehicle may have a high
performance dry sump lubrication
system. This system operates
differently than a standard engine
lubrication system. See Engine Oil
on page 10-12.
Check the oil level only after the
engine has been thoroughly warmed
up and then check between five and
10 minutes of shutoff. This ensures
that the oil level reading obtained
will be accurate.
Brake Noise
Under certain weather or operating
conditions, occasional brake squeal
may be heard with the vehicle's

In Brief 1-21
performance braking system. This
brake system is designed for
superior fade resistance and
consistent operation using high
performance brake pads. Brake
squeal is normal and does not affect
system performance.
Tire Chatter/Hop
When driving at slow speeds and in
very tight turns, the vehicle may
have tire chatter/hop. This condition
is normal and the vehicle does not
require service.
Road Imperfections/Crown Effects
The vehicle's precise steering and
handling make it very responsive to
road surface feedback. A slight pull
may be felt in the steering
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts. This is
normal and the vehicle does not
require service.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a CHANGE ENGINE
OIL SOON DIC message when it is
necessary to change the engine oil
and filter. The oil life system should
be reset to 100% only following an
oil change.
Resetting the Oil Life System
1. Scroll through the DIC InfoPages menu until the
REMAINING OIL LIFE
percentage is displayed. See
Driver Information Center (DIC)
on page 5-26.
2. Press and hold the SEL button on the DIC while the Oil Life
display is active. The oil life will
change to 100%.
See Engine Oil Life System on
page 10-18.
Car Wash Guidelines
{Caution
Some automatic car washes can
cause damage to the vehicle,
wheels, or convertible top,
if equipped. Automatic car
washes are not recommended,
due to lack of clearance for the
undercarriage and/or wide rear
tires and wheels. See "Washing
the Vehicle" under Exterior Care
on page 10-82
