THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15 WARNING! Leaving unattended children in a vehicle is dangerous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake, brake pedal, or the shift lever. Do not leave the key in the ignition. A child could operate power windows, other controls, or move the vehicle. Key-In-Ignition Reminder Opening the driver's door when the key is in the ignition sounds a signal to remind you to remove the key. NOTE: The Key-In-Ignition reminder only sounds when the ignition key is placed in the LOCK or ACC position. SENTRY KEYா The Sentry Key௡ Immobilizer System prevents unauthorized vehicle operation by disabling the engine. The system does not need to be armed or activated. Operation is automatic, regardless of whether the vehicle is locked or unlocked. The system uses ignition keys that have an embedded electronic chip (transponder) to prevent unauthorized vehicle operation. Therefore, only keys that are programmed to the vehicle can be used to start and operate the vehicle. The system will shut the engine off in two seconds if someone uses an invalid key to try to start the engine. 2 CAUTION! An unlocked vehicle is an invitation to thieves. Always remove the key from the ignition, and lock all doors when leaving the vehicle unattended.
