28 IN BRIEF
Car Wash Guidelines
Caution
Some automatic car washes can
cause damage to the vehicle, wheels
and ground effects. Automatic car
washes are not recommended, due
to lack of clearance for the
undercarriage and/or wide rear tires
and wheels. See "Washing the
Vehicle" underExterior Care0329.
Driving for Better Fuel
Economy
Driving habits can affect fuel mileage.
Here are some driving tips to get the
best fuel economy possible.
.
Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid abrupt
stops.
. Avoid idling the engine for long
periods of time. .
When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed limits
or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated.
. Combine several trips into a
single trip.
. Replace the vehicle's tires with the
same TPC Spec number molded
into the tire's sidewall near
the size.
. Follow recommended scheduled
maintenance.

30 KEYS, DOORS, AND WINDOWS
This key, inside the Remote Keyless
Entry (RKE) transmitter, is used for
the driver door and rear folding seats.To remove the key, press the button
on the side of the transmitter near the
bottom, and pull the key out. Never
pull the key out without pressing the
button.
See your dealer if a new key is needed.
Contact Roadside Service if locked out
of the vehicle. See
Roadside Service
0 361.
With an active OnStar service plan, an
OnStar Advisor may remotely unlock
the vehicle. See OnStar Overview 0371.
Remote Keyless Entry
(RKE) System
See Radio Frequency Statement 0367.
If there is a decrease in the Remote
Keyless Entry (RKE) operating range:
. Check the distance. The
transmitter may be too far from
the vehicle.
. Check the location. Other vehicles
or objects may be blocking the
signal. .
Check the transmitter's battery.
See “Battery Replacement ”later in
this section.
. If the transmitter is still not
working correctly, see your dealer
or a qualified technician for
service.
Remote Keyless Entry
(RKE) System Operation
The Keyless Access system allows for
vehicle entry when the Remote
Keyless Entry (RKE) transmitter is
within 1 m (3 ft). See “Keyless Access
Operation ”later in this section.
The RKE transmitter may work up to
60 m (197 ft) away from the vehicle.

11349156) - 2018 - CRC - 9/29/17
46 KEYS, DOORS, AND WINDOWS
The power sounder provides an
audible alarm which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm
if the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.
Immobilizer
SeeRadio Frequency Statement 0367.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is turned
on or to ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
located in the center console.
If the ignition modes will not change
with the other transmitter or in the
transmitter pocket, the vehicle needs
service. If the ignition does change
modes, the first transmitter may be
faulty. See your dealer.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 030.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
