Caution
The vehicle may be equipped with an
electric parking brake and/or an
electronic shifter. In the event of a loss of
12-volt battery power, the electric parking
brake cannot be released, and the vehicle
cannot be shifted to N (Neutral). Tire
skates or dollies must be used under the
non-rolling tires to prevent damage while
loading/unloading the vehicle. Dragging
the vehicle will cause damage not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with a tow
eye. Improper use of the tow eye may
cause damage to the vehicle and is not
covered by the vehicle warranty.
If equipped, use the tow eye to load the
vehicle onto a flatbed tow truck from a
flat road surface, or to move the vehicle
a very short distance at a walking pace.
The tow eye is not designed for off-road
recovery. The vehicle must be in
N (Neutral) with the electric parking
brake released when using the tow eye.Contact a professional towing service if the
disabled vehicle must be transported. GM
recommends a flatbed tow truck to
transport a disabled vehicle. Use ramps to
help reduce approach angles, if necessary.
If equipped, a tow eye may be located near
the spare tire or emergency jack. Do not use
the tow eye to pull the vehicle from the
snow, mud, sand, or ditch. Tow eye threads
may have right or left-hand threads. Use
caution when installing or removing the
tow eye.
The vehicle must be in N (Neutral) and the
electric parking brake must be released
when loading the vehicle onto a flatbed tow
truck.
Vehicles Equipped with Electronic Shifter
The vehicle must be in N (Neutral) and the
electric parking brake must be released
when loading the vehicle onto a flatbed tow
truck.
.If the vehicle is equipped with car wash
mode and has 12-volt battery power, refer
to
“Car Wash Mode” underAutomatic
Transmission (Mechanical Shifter) 0231 or
Automatic Transmission (Electronic Shifter)
0 233 to place the vehicle in N (Neutral).
.If the 12-volt battery is dead and/or the
engine will not start, the vehicle will not
move. Try to jump start the vehicle. Refer
toJump Starting - North America 0407
and if the jump start is successful, retry
the “Car Wash Mode” procedure.
Vehicles Equipped with Mechanical
Transmission Range Select Shifter
.The vehicle must be in N (Neutral) and
the Electric Parking Brake must be
released when loading the vehicle onto a
flatbed tow truck. If the 12-volt battery is
dead and/or Electric Parking Brake is not
released, the vehicle will not move. Try to
jump start the vehicle with a known good
12-volt battery, shift the car into
N (Neutral), and release the Electric
Parking Brake. Refer to Jump Starting -
North America 0407.
If jump starting is unsuccessful, the vehicle

Vehicle Care 415
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.

(Continued)
Caution (Continued)
not recommended, due to lack of
clearance for the undercarriage and/or
wide rear tires and wheels.
Caution
Automatic car washes can cause damage
to the vehicle, wheels, ground effects,
and convertible top (if equipped).
Do not use automatic car washes due to
lack of clearance for the undercarriage,
wide rear tires, and wheels.
If using an automatic car wash, follow with
the car wash instructions. The windshield
wiper and rear window wiper, if equipped,
must be turned off. Remove any accessories
that may be damaged or interfere with the
car wash equipment.
See Power Assist Steps 030 for cleaning
information.
Rinse the vehicle well, before washing and
after, to remove all cleaning agents
completely. If they are allowed to dry on
the surface, they could stain. 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's 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, or flat paint as damage can occur.
