2010 JEEP GRAND CHEROKEE tire pressure

thorized dealer-installed options, must be
considered as part of the total load on your
vehicle.
Towing RequirementsTo promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
•Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
• Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts at
full throttle. This helps the engine and other
parts of the vehicle wear in at the heavier
loads.
Perform the maintenance listed in the “Mainte-
nance Schedule.” Refer to “Maintenance
Schedule” for the proper maintenance inter-
vals. When towing a trailer, never exceed the
GAWR or GCWR ratings.
WARNING!
Improper towing can lead to an injury acci-
dent. Follow these guidelines to make your
trailer towing as safe as possible:
•
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured, dy-
namic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have an accident.
• When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.
(Continued)
WARNING!(Continued)
• Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or chock the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Trailer tongue weight rating for the trailer
hitch utilized.
Towing Requirements – Tires
Proper tire inflation pressures are essential to the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
247

Check the trailer tires for proper tire inflationpressures before trailer usage.
Check for signs of tire wear or visible tire damage before towing a trailer. Refer to
“Tires – General Information” in “Starting and
Operating” for proper inspection procedure.
When replacing tires, refer to “Tires – Gen- eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying
capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
Do notinterconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
An electronically-actuated trailer brake con- troller is required when towing a trailer with
electronically-actuated brakes. When towing
a trailer equipped with a hydraulic surge-
actuated brake system, an electronic brake
controller is not required. Trailer brakes are recommended for trailers
over 1,000 lbs (454 kg), and required for
trailers in excess of 1,654 lbs (750 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs
(454 kg) loaded, it should have its own brakes
and they should be of adequate capacity.
Failure to do this could lead to accelerated
brake lining wear, higher brake pedal effort,
and longer stopping distances.
WARNING!
• Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system and cause it to fail. You
might not have brakes when you need
them and could have an accident.
• Towing any trailer will increase your stop-
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an accident. Towing Requirements – Trailer Lights and
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package includes a 13 pin
wiring harness. Use a factory approved trailer
harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.
248

•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the coolant recovery
bottle and radiator. Inspect the entire system
for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling sys-
tem pressure cap for proper vacuum sealing by
draining a small amount of engine coolant
(antifreeze) from the radiator drain cock. If the
cap is sealing properly, the engine coolant
(antifreeze) will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOL-
ANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System – Drain, Flush, and Refill
If the engine coolant (antifreeze) is dirty and
contains a considerable amount of sediment,
clean and flush with reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended en-
gine coolant (antifreeze). Refer to “Fluids, Lu-
bricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.CAUTION!
•
Mixing of engine coolant (antifreeze), other
than the specified HOAT engine coolant
(antifreeze), may result in engine damage
and may decrease corrosion protection. If a
non-HOAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, it should be replaced with the
specified engine coolant (antifreeze) as
soon as possible.

•
When installing the totally integrated power
module cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the totally integrated power module
and possibly result in a electrical system
failure.
• When replacing a blown fuse, it is important
to use only a fuse having the correct am-
perage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
VEHICLE STORAGEIf you are leaving your vehicle dormant for more
than 21 days you may want to take steps to
protect your battery. You may:
• Remove fuse #27 in the Totally Integrated
Power Module (TIPM) labeled Ignition-Off
Draw (IOD#1).

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-
quired” will be displayed in the EVIC and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11 200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
•The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
6 months since your last oil change even
if the oil change indicator message is
NOT illuminated. •
Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time.
• Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required. Once a Month
•
Check tire pressure and look for unusual
wear or damage.
