effort and travel is increased. When the
message displays, the driver should decrease
brake pedal pressure.
Stage 2 :The Driver Information Center
(DIC) displays a “Brakes Overheated Service
Now” message that the brake fluid
temperature is excessive and is about to
boil. The system increases brake pedal effort
and travel, and will also limit vehicle speed.
The driver should immediately start a cool
down lap if on the track. If this message
displays, take the vehicle to be serviced at
your dealer.
Brake Burnishing
New brake pads must be burnished before
racing or other competitive driving.
Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In 0192.
Caution
Brake pedal fade will occur during any
track burnish procedure and can cause
brake pedal travel and force to increase.
This could extend stopping distance until
the brakes are fully burnished.
When this procedure is performed as
instructed, it will not damage the brakes.
The brake pads will smoke and produce an
odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation. Brake Burnishing Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Apply the brakes 25 times starting at 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application without activating the
Antilock Brake System (ABS). Drive for at
least 1 km (0.6 mi) between applications.
Depending on conditions, some increase
in brake pedal travel and brake pedal
force may be experienced.
3. Cool down: Drive at 100 km/h (60 mph) for approximately 15 km (10 mi) without
using the brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applications.

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.

14622938) - 2021 - CRC - 2/10/21
288 Vehicle Care
Body Damage
If the vehicle is damaged and requires sheet
metal repair or replacement, make sure the
body repair shop applies anti-corrosion
material to parts repaired or replaced to
restore corrosion protection.
Original manufacturer replacement parts will
provide the corrosion protection while
maintaining the vehicle warranty.
Finish Damage
Quickly repair minor chips and scratches
with touch-up materials available from your
dealer. Larger areas of finish damage can be
corrected in your dealer's body and
paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and attack
painted vehicle surfaces causing blotchy,
ring-shaped discolorations, and small,
irregular dark spots etched into the paint
surface. See“Finish Care” previously in this
section.
Interior Care
To prevent dirt particle abrasions, regularly
clean the vehicle's interior. Immediately
remove any soils. Newspapers or dark
garments can transfer color to the vehicle’s
interior.
Use a soft bristle brush to remove dust from
knobs and crevices on the instrument
cluster. Using a mild soap and water
solution, immediately remove hand lotions,
sunscreen, and insect repellent from all
interior surfaces or permanent damage may
result.
For liquid cleaners, use approximately
20 drops per 3.8 L (1 gal) of water.
A concentrated soap solution will create
streaks and attract dirt.
Use cleaners specifically designed for the
surfaces being cleaned to prevent
permanent damage. Apply all cleaners
directly to the cleaning cloth. Do not spray
cleaners on any switches or controls.
Remove cleaners quickly.
Before using cleaners, read and follow all
safety instructions on the label. While
cleaning the interior, open the doors and
windows to get proper ventilation.
Caution
To prevent damage:
.Never use a razor or any other sharp
object to remove soil from any interior
surface
.Never use a brush with stiff bristles.
.Never rub any surface aggressively or
with too much pressure.
.Do not get any exposed electrical
components wet.
.Do not use laundry detergents or
dishwashing soaps with degreasers. Do
not use solutions that contain strong
or caustic soap.
.Do not heavily saturate the upholstery
when cleaning.
.Do not use solvents or cleaners
containing solvents.
.Do not use disinfecting wipes that are
scented or contain bleach. Do not use
wipes or cleaners that show a color
transfer to the wipe or change the
appearance of the interior surface
when used.
