198 Driving and Operating
Warning (Continued)
If unusual fumes are detected or if it is
suspected that exhaust is coming into the
vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired immediately.
Never park the vehicle with the engine
running in an enclosed area such as a
garage or a building that has no fresh air
ventilation.
{Warning
To prevent exhaust gases from entering
the vehicle and heat from damaging the
vehicle, the engine cover and all fluid fill
plugs must be secured before closing the
tonneau cover (convertible only) and
operating the vehicle. Make sure all bolts
are torqued to GM specifications.
Running the Vehicle While Parked
It is better not to park with the engine
running. If the vehicle is left with the engine running,
follow the proper steps to be sure the
vehicle will not move. See
Shifting Into Park
0 196 and
Engine Exhaust 0197.
Dual Clutch Transmission
This vehicle is equipped with a dual clutch
transmission that contains an integrated
rear differential. The dual clutch
transmission provides an extremely
connected feel due to the direct connection
between the engine and gear box. This
arrangement provides very fast shift times
for maximum performance. Automatic
driving mode is selected by pulling D on the
transmission range selection panel and provides fully automatic shifting operation
which can be further refined using driver
mode control. Upshifts may be delayed
regardless of mode selection or ambient
temperature until the engine is warmed up.
Manual operation can also be selected. See
Manual Mode later in this section.
This transmission is electronically controlled.
The shift switches are on the center console.
The selected gear position will illuminate red
on the shift switch, while all others will
display in white. The indicator on the shift
switch may flash if the shift is not
immediate or if the gear is not fully
engaged. This may occur in very cold
conditions or when Double Paddle Declutch
is used.
The transmission does not operate when the
vehicle is off.
If the vehicle is in ACC/ACCESSORY, the
transmission can be shifted into P (Park).
If ENGINE START/STOP is pressed twice while
at a relatively high speed, the engine will
turn off and the transmission will
automatically shift into N (Neutral). Once the
vehicle is stopped, P (Park) can be selected.

284 Vehicle Care
Caution (Continued)
This could cause damage that would not
be covered by the vehicle warranty.
Solvents or aggressive cleaners may harm
underhood components. The usages of these
chemicals should be avoided. Recommend
water only.
A pressure washer may be used, but care
must be utilized. The following criteria must
be followed:
.Water pressure must be kept below
14,000 KPa (2,000 PSI).
.Water temperature must be below 80 °C
(180 °F).
.Spray nozzle with a 40 degree wide angle
spray pattern or wider must be used.
.Nozzle must be kept at least 30 cm (1 ft)
away from all surfaces.
Automatic Car Wash
Caution
Automatic car washes can cause damage
to the vehicle, wheels, ground effects,
and convertible top (if equipped).
(Continued)
Caution (Continued)
Do not use automatic car washes due to
lack of clearance for the undercarriage,
wide rear tires, and wheels.
Hand Wash
Rinse the vehicle well, before washing and
after, to remove all cleaning agents
completely. If they dry on the surface
staining could occur.
Dry the finish with a soft, clean chamois or
an all-cotton towel to avoid surface
scratches and water spotting.
Finish Care
Application of aftermarket clearcoat sealant/
wax materials is not recommended.
If painted surfaces are damaged, see your
dealer to have the damage assessed and
repaired. Foreign materials such as calcium
chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings,
chemicals from industrial chimneys, etc., can
damage the vehicle finish if they remain on
painted surfaces. Wash the vehicle as soon
as possible. If necessary, use non-abrasive
cleaners that are marked safe for painted
surfaces to remove foreign matter. Occasional hand waxing or mild polishing
should be done to remove residue from the
paint finish. See your dealer for approved
cleaning products.
Do not apply waxes or polishes to uncoated
plastic, vinyl, rubber, decals, simulated
wood, flat paint, or metal mesh grilles as
damage can occur.
Caution
Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
finish may damage it. Use only
non-abrasive waxes and polishes that are
made for a basecoat/clearcoat paint finish
on the vehicle.
To keep the paint finish looking new, keep
the vehicle garaged or covered whenever
possible.
Protecting Exterior Bright Metal Moldings
Caution
Failure to clean and protect the bright
metal moldings can result in a hazy
white finish or pitting. This damage
would not be covered by the vehicle
warranty.
