DRIVER ADJUSTABLE PEDALS — IF
EQUIPPED
The adjustable pedals system is designed to
allow a greater range of driver comfort for
steering wheel tilt and seat position. This
feature allows the brake and accelerator pedals
to move toward or away from the driver to
provide improved position with the steering
wheel.
The adjustable pedal switch is located to the left
side of the steering column.

Adjustable Pedals Switch
NOTE:
The pedals can be adjusted with the ignition
OFF.
The pedals cannot be adjusted when the
vehicle is in REVERSE or when the Speed
Control System is on. The following messages
will appear on vehicles equipped with an
instrument cluster display if the pedals are
attempted to be adjusted when the system is
locked out: “Adjustable Pedal Disabled —
Cruise Control Engaged” or “Adjustable Pedal
Disabled — Vehicle In Reverse”.
NOTE:
Always adjust the pedals to a position that
allows full pedal travel.
Further small adjustments may be necessary
to find the best possible seat/pedal position.
For vehicles equipped with Driver Memory
Seat, you can use your remote keyless entry
key fob or the memory switch on the driver’s
door trim panel to return the adjustable
pedals to pre-programmed positions. Refer
to “Driver Memory Seat” in “Seats” in this
chapter for further information.
WARNING!
Do not adjust the pedals while the vehicle is
moving. You could lose control and have an
accident. Always adjust the pedals while the
vehicle is parked.
CAUTION!
Do not place any article under the adjustable
pedals or impede its ability to move, as it may
cause damage to the pedal controls. Pedal
travel may become limited if movement is
stopped by an obstruction in the adjustable
pedal's path.
