Both the CT4 and TLX have child safety locks to prevent children from opening the rear doors. The CT4 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CT4 are reminded to check the back seat if they opened the rear door before starting out. The TLX doesn’t offer a back seat reminder.

The CT4’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The TLX doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The CT4 Premium Luxury/Sport has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision.

The CT4 has 1.1 inches more front headroom and .2 inches more rear headroom than the TLX.

The CT4 has a 1000 lbs. towing capacity. The TLX has no towing capacity.
