Stop/Start System - Cadillac XT4 2023 Owner's Manual

Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0 253.
To start the vehicle:
1. With the Keyless Access system, the
remote key must be in the vehicle. Press
ENGINE START/STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button. The idle
speed will go down as the engine warms
up. Do not race the engine immediately
after starting it.
If the remote key is not in the vehicle,
if there is interference, or if the remote
key battery is low, a Driver Information
Centre (DIC) message will display. See
Remote Key Operation 0 7.
Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP
immediately after cranking has ended,
can overheat and damage the cranking

motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
2. If the engine does not start after five to
10 seconds, especially in very cold
weather (below 18 °C or 0 °F), it could
be flooded with too much petrol. Try
pushing the accelerator pedal all the way
to the floor and hold it there, then press
ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the button
and the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra petrol
from the engine. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently until
the oil warms up and lubricates all
moving parts.

Driving and Operating

Stop/Start System

The Stop/Start system will shut off the
engine to help conserve fuel. It has
components designed for the increased
number of starts.
Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See Rev Counter 0 93. When
the brake pedal is released or the
accelerator pedal is depressed, the engine
will restart.
To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released.
