Starting Procedure
1. With your foot off theaccelerator pedal, turn the
ignition to START. When the
engine cranks, let go of the
key. The idle speed will go
down as the engine gets warm.
Caution
Holding the key in START for
longer than 15 seconds at a time
will cause the battery to be
drained much sooner. And the
excessive heat can damage the
starter motor. Wait about
15 seconds between each try to
help avoid draining the battery or
damaging the starter.
2. If the engine does not start, wait about 15 seconds and try
again. Wait about 15 seconds
between each try.
When the engine has run about
10 seconds to warm up, the
vehicle is ready to be driven.
Do not run the engine at high
speed when it is cold. If the weather is below freezing
(0 °C or 32 °F), let the engine
run for a few minutes to
warm up.
3. If the engine still will not start, or starts but then stops, it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
about three seconds. If the
vehicle starts briefly but then
stops again, do the same thing,
but this time keep the pedal
down for five or six seconds.
This clears the extra gasoline
from the engine.
Engine Heater
The engine heater can provide
easier starting and better fuel
economy during engine warm-up in
cold weather conditions at or below
−18 °C (0 °F). Vehicles with an
engine heater should be plugged in
at least four hours before starting.
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is
located in the driver side of the
engine compartment, near the
battery. It is shipped from the
factory with a tie holding it in
place. Use care in removing
the tie so that the cord is not
damaged.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.

continue to work for 10 minutes after
the last input (button press, knob
turn) to the radio is detected.
It is possible to turn the radio back
on at any time after it has timed out
using the Power knob. The radio will
be functional for 10 minutes after the
last input (button press, knob turn)
to the radio is detected.
Shifting Into Park
(Automatic Transmission)
1. Hold the brake pedal down andset the parking brake. See
Parking Brake 0202.
2. Move the shift lever into P (Park) by pressing the button
on the shift lever and pushing
the lever all the way toward the
front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can leave the
vehicle with the ignition key in
your hand, the vehicle is in
P (Park).
Leaving the Vehicle with the
Engine Running (Automatic
Transmission)
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park (Automatic
Transmission) 0195.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold the
brake pedal down. Then see if you
can move the shift lever away from
P (Park) without first pushing the
button on the shift lever. If you can,
it means that the shift lever was not
fully locked into P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle may put too much force on
the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called
“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
“Shifting Into Park” previously in this
section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.

Chevrolet Sonic Owner Manual (GMNA-Localizing-U.S/Canada-9085902) -
2016 - CRC - 5/27/15
196 Driving and Operating
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission, so you can pull
the shift lever out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with a shift
lock control. The shift lock control is
designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park) with the shift lever
button fully released.
. Prevent movement of the shift
lever out of P (Park) unless the
ignition is in ON/RUN and the
brake pedal is applied.
The shift lock control is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the

Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has an HSA feature,
which may be useful when the
vehicle is stopped on a grade
sufficient enough to activate HSA.
This feature is designed to prevent
the vehicle from rolling, eitherforward or rearward, during vehicle
drive off. After the driver completely
stops and holds the vehicle in a
complete standstill on a grade, HSA
will be automatically activated.
During the transition period between
when the driver releases the brake
pedal and starts to accelerate to
drive off on a grade, HSA holds the
braking pressure for a maximum of
two seconds to ensure that there is
no rolling. The brakes will
automatically release when the
accelerator pedal is applied within
the two-second window. It will not
activate if the vehicle is in a drive
gear and facing downhill, or if the
vehicle is facing uphill and in
R (Reverse).
