2008 JEEP GRAND CHEROKEE warning light

should be replaced immediately! Eventual deterioration
of the hose can take place resulting in a possibility of a
burst failure.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Fluid Level Check
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning light indicates system failure.Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
ªFULLº mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid, refer
to Fluids, Lubricants and Genuine Parts for correct fluid
type.

BULB REPLACEMENT
High Intensity Discharge Headlights (HID) Ð If
Equipped
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
High Intensity Discharge (HID) headlights when the
headlight switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.NOTE:On vehicles equipped with High Intensity Dis-
charge Headlights (HID), when the headlights are turned
on, there is a blue hue to the lights. This diminishes and
becomes more white after approximately 10 seconds, as
the system charges.
