Jeep 2005 Liberty - Manual (Page 220)

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle.
4WD Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.
