sae JEEP COMMANDER 2009 1.G Owners Manual

•Do not install tire chains or traction devices on ve-
hicles with larger than 235/65R17XL size tires. Tires
larger than this may not provide sufficient body
clearance with chains or other traction devices.
•Manufacturer recommends a cold inflation pressure of
38 psi (262 kPa) when using 235/65R17XL size tires for
this vehicle.
•Use SAE class “S” tire chains or traction devices only.
•Follow tire chain manufacturer’s instructions for
mounting chains.
•Install chains snugly and tighten after 1/2 mi (1 km) of
driving.
•Do notexceed 30 mph (48 km/h), unless otherwise
specified by the chain manufacturer.
•Drive cautiously, avoiding large bumps, potholes and
extreme driving maneuvers.
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates and develop irregular wear patterns.
The suggested rotation method is the “forward-cross”
shown in the following diagram.

Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of Chrysler Material
Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section.
NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to “Multi-Displacement System” in Section 5 for
more details.
Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
