JEEP GRAND CHEROKEE 2004 WK / 3.G Workshop Manual

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a

garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.

MIRRORS
Inside Day/Night Mirror
The mirror should be adjusted to center on the view
through the rear window. A two-point pivot system
allows for horizontal and vertical adjustment of the
mirror. The mirror should be adjusted while set in the
day position (toward windshield).
Annoying headlight glare from vehicles behind you can
be reduced by moving the small control under the mirror
to the night position (toward rear of vehicle).

Inside Automatic Dimming Mirror Ð If Equipped
This mirror automatically adjusts for annoying headlight
glare from vehicles behind you. You can turn the feature
on or off by pressing the button at the base of the mirror.
A light in the button will indicate when the dimming
feature is activated.CAUTION!
To avoid damage to the mirror during cleaning,
never spray any cleaning solution directly onto the
mirror. Apply the solution onto a clean cloth and
wipe the mirror clean.
Driver's Outside Automatic Dimming Mirror Ð If
Equipped
If your vehicle is equipped with a driver's outside
automatic dimming mirror, it operates when the inside
automatic dimming mirror is on. This outside mirror
operates off the inside mirror switch and will automati-
cally adjust for annoying headlight glare when the inside
mirror does.
NOTE:The passenger outside mirror does not have this
dimming feature.
