Liftgate CAUTION: (Continued) {CAUTION: It can be dangerous to drive with the liftgate open because carbon monoxide (CO) gas can come into your vehicle. You cannot see or smell CO. It can cause unconsciousness and even death. If you must drive with the liftgate open, or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate: • Make sure all other windows are shut. • Turn the fan on your heating or cooling system to its highest speed with the recirculation mode off. That will force outside air into your vehicle. See Climate Control System on page 199. CAUTION: (Continued) • If you have air outlets on or under the instrument panel, open them all the way. • If your vehicle has a power liftgate, disable the power liftgate function. See Power Liftgate on page 110. If your vehicle has a power liftgate, see Power Liftgate on page 110.

See Remote Keyless Entry (RKE) System Operation on page 100. To open the liftgate, press the touchpad on the underside of the liftgate handle. The vehicle must be in PARK (P) to open the liftgate. To close the liftgate, use the pull cup or pull strap as an aid. 109
