Driving and Operating 225
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
For hybrid vehicles, the engine will
always be off while in N (Neutral).
The vehicle cannot charge the high
voltage battery while the shift lever is in N (Neutral). Only use
N (Neutral) when required. If the
high voltage battery state of charge
is low, the Driver Information
Center (DIC) will display a message
to shift out of N (Neutral). Shift to
P (Park), R (Reverse), D (Drive),
or L (Low) depending on the
situation. If the high voltage battery
is depleted too far, the vehicle will
shut down, requiring a shift to
P (Park) to restart the vehicle.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
D : This position is for normal
driving. If more power is needed for
passing, press the accelerator
pedal down. L :
This position allows you to
change gears similar to a manual
transmission. If the vehicle has this
feature, see Manual Mode 0225.
Operating Modes
The transmission may operate in a
lower gear than normal to improve
vehicle performance. The engine
speed may be higher and there may
be an increase in noise during the
following conditions:
. When climbing a grade.
. When driving downhill.
. When driving in hot
temperatures or at high altitude.
Manual Mode
Electronic Range Select
(ERS) Mode
ERS mode allows you to choose the
top-gear limit of the transmission
and the vehicle's speed while
driving downhill or towing a trailer.
The vehicle has an electronic shift
position indicator within the
instrument cluster. When using the

Chevrolet Malibu Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11348460) - 2018 - crc - 5/3/17
226 Driving and Operating
ERS mode a number will display
next to the L, indicating the current
gear that has been selected.
To use this feature:1. Move the shift lever to L (Manual Mode).
2. Press + (Plus) or −(Minus) on
the shift lever to increase or
decrease the gear range
available.
When you shift from D (Drive) to
L (Manual Mode), the transmission
will shift to a pre-determined lower
gear range. The highest gear
available for this pre-determined
range is displayed next to the L in the DIC.
See
Driver Information Center (DIC)
(Uplevel) 0134 orDriver Information
Center (DIC) (Base Level) 0131.
The number displayed in the DIC is
the highest gear that the
transmission will be allowed to
operate in. This means that all
gears below that number are
available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive).
While in L (Manual Mode), the
transmission will prevent shifting to
a lower gear range if the engine
speed is too high. You have a brief
period of time to slow the vehicle.
If vehicle speed is not reduced
within the time allowed, the lower
gear range shift will not be
completed. You must further slow
the vehicle, then press the −(Minus)
button to the desired lower gear
range.
Hybrid Low Mode
L2 provides the ability to slow the
vehicle without using the brakes. L2
provides moderate braking and L1
provides maximum braking below
80 km/h (50 mph). Use L (Low) when
descending steep grades or in
stop-and-go traffic. When the
battery reaches full charge the
engine may run to maintain braking.
To use this feature:
1. Move the shift lever to L (Low). The transmission will enter L2.
2. Press + (Plus) or −(Minus) on
the shift lever to shift between
L2 and L1.

Electric Parking Brake
The vehicle may have an Electric
Parking Brake (EPB). The EPB can
always be activated, even if the
ignition is off. To prevent draining
the battery, avoid repeated cycles of
the EPB system when the engine is not running. In case of insufficient
electrical power, the EPB cannot be
applied or released.
The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light.

and the stopping distance may be
longer.Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck 0212
and “Turning the Systems Off and
On” later in this section.

232 Driving and Operating
The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
Turning the Systems Off

Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active driver
steering, an alert, chime, or DIC
message may be provided. Move
the steering wheel to dismiss.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads. If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
A system unavailable message may
display if the camera is blocked.
The LKA system does not need
service.
LKA assistance and/or LDW alerts
may occur due to tar marks,
shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LKA off if these
conditions continue.
Fuel
GM recommends the use of TOP
TIER®detergent gasoline to keep
the engine cleaner and reduce
engine deposits. See
www.toptiergas.com for a list of TOP
TIER detergent gasoline marketers
and applicable countries.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
For vehicles with the 1.5L L4 engine
and the 1.8L Hybrid, use regular
unleaded gasoline meeting ASTM
specification D4814 with a posted

Chevrolet Malibu Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11348460) - 2018 - crc - 5/3/17
258 Driving and Operating
octane rating of 87 or higher. Do not
use gasoline with a posted octane
rating of less than 87, as this may
cause engine knock and will lower
fuel economy.
For vehicles with the 2.0L L4
engine, premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93 is
highly recommended for best
performance and fuel economy.
Unleaded gasoline with an octane
rated as low as 87 can be used.
Using unleaded gasoline rated
below 93 octane, however, will lead
to reduced acceleration and fuel
economy. If knocking occurs, use a
gasoline rated at 93 octane as soon
as possible, otherwise, the engine
could be damaged. If heavy
knocking is heard when using
gasoline with a 93 octane rating, the
engine needs service.Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
. For vehicles which are not
FlexFuel, fuel labeled
greater than 15% ethanol by
volume, such as mid-level
ethanol blends (16 –50%
ethanol), E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control
system and spark plugs.
(Continued)
Caution (Continued)
.Fuel with a posted octane
rating of less than the
recommended fuel. Using
this fuel will lower fuel
economy and performance,
and may decrease the life of
the emissions catalyst.
