Ride Height Descriptions
Normal
Normal height is the standard vehicle height
used for everyday driving.
Entry/Exit
Entry/Exit height is 50 mm (2 in) lower than
Normal height. This ride height lowers the
vehicle for easy entry and exit, and loading
and unloading of cargo.
This ride height can be selected in the Ride
Height Menu at any vehicle speed; but will
not lower until the vehicle slows to less
than 15 km/h (9 mph).
If a door is opened after lowering to Entry/
Exit height, the vehicle automatically raises
to Normal height from Entry/Exit height
when speed increases above 16 km/h
(10 mph). If no door is opened after lowering
to Entry/Exit Height, the vehicle waits to
raise to Normal height until the speed
increases above 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 Easy Exit Vehicle
Height Mode to automatically lower to
Entry/Exit Height when the vehicle is shifted
to P (Park). Easy Exit Vehicle Height Mode
may be enabled via the infotainment screen
under Settings > Vehicle > Ride Height.
When the vehicle is higher than Normal
height, Easy Exit Vehicle Height Mode is
disabled. When the vehicle is in Tow/Haul
Mode, Off-Road Mode, Terrain Mode, or it
senses a trailer is connected, Easy Exit
Vehicle Height Mode is disabled.
Increased
Increased height is 46 mm (2 in) higher than
Normal height. This ride height raises the
vehicle for off-road use. Increased height can
be selected in the Ride Height Menu while
vehicle speed is less than 80 km/h (50 mph).
Extract Mode
If equipped and enabled, prior to selecting
Extract Mode in the Ride Height menu,
ensure the vehicle speed is less than
20 km/h (12 mph), the vehicle is in Terrain
mode, and the steering wheel is centered.
Driving and Operating
Extract Mode raises the vehicle to the
maximum ride height, up to 149 mm
(5.9 inches) higher than the Normal height.
Vehicle loading, road surface, and starting
ride height may affect the maximum ride
height and time it takes to raise the vehicle.
To ensure that the vehicle reaches its
highest ride height, it is recommended to
enable Extract Mode prior to reaching an
obstacle where additional ground clearance
is necessary.
When Extract Mode is activated, the vehicle
speed is restricted to 20 km/h (12 mph).
Extract Mode is intended only for additional
ground clearance in off-road use. The speed
restriction is removed when the ride height
returns below Increased height.
If an unsafe condition is detected, the air
suspension may automatically exit Extract
Mode and lower the vehicle.
If the selection of Extract Mode displays
LEVELING SYSTEM UNAVAILABLE on the
Driver Information Center (DIC), the air
springs may be at the maximum height or
the Air Suspension System may need to cool
down. See the System Over-Temperature
section below for more information.
