unavailable for selection will be greyed out
in the menu.
Ride Height Descriptions
Normal Height is the standard vehicle height
used for everyday driving.
Entry/Exit Height
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 from any
door or the rear liftgate.
This ride height can be selected in the Ride
Height Menu at any vehicle speed. When
Entry/Exit Height is selected 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 toraise 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.
When the vehicle is in Tow/Haul Driver
Mode, Off-Road Driver Mode, or it senses a
trailer is connected, Automatic Entry/Egress
Mode is disabled.
Increased Height
Increased Height is 25 mm (1 in) higher than
Normal Height. This ride height raises the
vehicle for off-road use, allows for higher
speeds than Maximum Height, and is only
available with specific optional content.
Increased Height can be selected in the Ride
Height Menu while vehicle speed is less
than 80 km/h (50 mph). If vehicle speed
exceeds 80 km/h (50 mph), the vehicle will
automatically lower to Normal Height.
Off-Road Driver Mode and Terrain Driver
Mode will automatically set Increased
Height when vehicle speed is less than
80 km/h (50 mph). If vehicle speed exceeds
80 km/h (50 mph), the vehicle will lower to
Normal Height. Normal Height will be
maintained until vehicle speed is slowed to
less than 16 km/h (10 mph) and then the
vehicle will automatically raise back to
Increased Height.
The vehicle will automatically lower from
Increased Height to Normal Height to
provide improved stability if aggressive
maneuvers are detected.
Maximum Height
Maximum Height is 50 mm (2 in) higher
than Normal Height. This ride height raises
the vehicle for off-road use and is only
available with specific optional content.
To raise the vehicle to Maximum Height,
first shift the transfer case to 4
n. Once the
transfer case is in 4
nand vehicle speed is
less than 48 km/hr (30 mph), select
Maximum Height in the Ride Height Menu.
If vehicle speed exceeds 48 km/h, the
vehicle will automatically lower to Increased
Height.

Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-15555985) - 2022 - CRC - 12/3/21
242 Driving and Operating
The vehicle will automatically lower from
Maximum Height to Normal Height to
provide improved stability if aggressive
maneuvers are detected.
Aerodynamic Height
Aerodynamic Height is 20 mm (0.75 in)
lower than Normal Height. This ride height
lowers the vehicle at higher vehicle speeds
to improve aerodynamics.
The vehicle will lower to Aerodynamic
Height when vehicle speed exceeds
105 km/h (65 mph) for a period of time. The
vehicle will raise to Normal Height when the
vehicle slows to less than 48 km/h
(30 mph).
Aerodynamic Height is automatically
disabled when a trailer is connected to the
vehicle or Tow/Haul Driver Mode is active.
Suspension Modes
The air suspension has two special modes
located in the infotainment screen under
Settings/Vehicle/Suspension. When either is
active, the following amber icon will be
illuminated in the instrument cluster.
SeeFour Corner Air Suspension Light 0120.
Service Mode
Service Mode will disable all air suspension
operation including raising and lowering the
vehicle and operation of the air compressor.
This mode is useful when the vehicle is
being towed on a flat bed or when any
work under the vehicle is being performed.
Service Mode is automatically enabled when
the vehicle is put on a hoist or a floor jack
is used to raise a corner. Service Mode may
temporarily enable during intense off-road
situations to prevent damaging air
suspension activity. Service Mode
automatically disables when vehicle speed
exceeds 16 km/h (10 mph).
Alignment Mode
Alignment Mode will optimize the vehicle
height to provide the most accurate wheel
alignment. This mode should be enabled
once the vehicle is driven onto the
alignment station. To enable Alignment Mode, ensure the
vehicle is at Normal Height and shift the
vehicle to Neutral. Alignment Mode
automatically disables when vehicle speed
exceeds 16 km/h (10 mph).
Air Suspension Operation with Door(s) or
Hood Open
The air suspension will temporarily suspend
all height changes while the hood or any
door is open. The air suspension resumes
height changes once the hood and all doors
are closed. An open rear liftgate does not
suspend the air suspension operation.
System Over-Temperature
If the air suspension is under heavy use, the
system may temporarily suspend all height
changes to allow compressor cooldown.
When this occurs and a height change is
requested, a
‘Leveling System Unavailable’
message will be displayed in the instrument
cluster.
Suspension Lowered for Stability
In the event of a loss of Electronic Stability
Control, the air suspension will lower the
vehicle at higher speeds to provide increased
stability. This will be accompanied by a
‘Vehicle Lowering for Stability’ message in
the instrument cluster.
