Ride Height Descriptions
Normal Height is the standard vehicle height
used for everyday driving.
Entry/Exit Height is 50 mm (2 in) lower than
Normal Height. This ride height lowers the
vehicle for easy entry and exit from the
vehicle as well as providing a lower height
for loading and unloading cargo.
This ride height can be selected in the Ride
Height Menu at any vehicle speed. When
Entry/Exit Height is select at higher speeds,
the vehicle will wait to lower until the
vehicle slows to less than 12 km/h (7 mph).
The vehicle will automatically raise to
Normal Height from Entry/Exit Height when
speed increases above 8 km/h (5 mph). If no
door has been opened since lowering to
Entry/Exit Height, the vehicle will wait to
raise to Normal Height until 30 km/h
(19 mph). This gives the driver more
flexibility when lowering to Entry/Exit
Height for passenger pick up and drop off.
The driver can enable Automatic Entry/
Egress Mode to automatically lower to
Entry/Exit Height when the vehicle is shifted
to P (PARK). Automatic Entry/Egress Mode
may be enabled via the infotainment screen
under Settings/Vehicle/Ride Height. When
the vehicle is higher than Normal Height,
Automatic Entry/Egress Mode is disabled.

Mode, Off-Road Driver Mode, or it senses a
trailer is connected, Automatic Entry/Egress
Mode is disabled.
