Jeep Wrangler: GETTING TO KNOW YOUR VEHICLE / INTERIOR STORAGE AND EQUIPMENT
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating...
Other information:
The DEF gauge (located on the instrument
cluster display) will display the level of DEF
remaining in the tank.
NOTE:
Driving conditions (altitude, vehicle speed, load,
etc.) will affect the amount of DEF that is used
in your vehicle.
DEF Fill Procedure
NOTE:
For the correct DEF fluid type...
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools...
