Automatic Transmission - Chevrolet Sonic 2014 Owner's Manual

142 Driving and operating
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas.
Caution
Fuel grades other than those listed
on pages 3 178, 3 239 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine
performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Caution
Do not touch the catalytic
converter during engine operation,
because the catalytic converter is
very hot so the skin (i.e. hand or
body) can be burned. Let the
catalytic converter cool down for
over two hours under ambient
temperature after the engine has
been stopped before touching it.

Automatic transmission

The automatic transmission permits
manual gear shifting (manual mode)
or automatic gear shifting (automatic
mode).
The automatic transmission is an
electronically controlled six-speed
transmission.
Sixth gear is overdrive.
Starting the vehicle
1. After warming up the engine,
continue to press the brake pedal
while shifting the selector lever to
either the R, D, or M position.
Caution
Do not shift between D (Drive) and
R (Reverse) or P (Park) while the
vehicle is moving. This will cause
damage to your transmission and
personal injury.
