2009 JEEP GRAND CHEROKEE inflation pressure

Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” for proper tire inflation
procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” for proper inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” 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

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically-actuated trailer brake controller 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
2,000 lbs (907 kg).
