Getting to Know Your Yukon/Yukon Denali16
This feature allows you to start the
engine from outside the vehicle by using
the Remote Keyless Entry (RKE) trans-
mitter. The remote start capability must
be turned on using the Driver
Information Center.
The vehicle’s automatic climate control
system (if equipped) will default to a
heating or cooling mode based on
outside temperature, and the manual
climate control system will turn on at
the same setting as when the vehicle
was last turned off.
Starting the Vehicle
To remote-start the vehicle:
1.
Aim the RKE transmitter at the vehicle.
(Transmitter range is within approxi-
mately 200 feet of the vehicle.)
2. Press and release the (Lock)
button on the transmitter.
3. Immediately press and hold the
(Remote Start) button for about four
seconds.When the parking lamps
flash, release the button. The engine
will start and the parking lamps will
remain on.
The engine will continue
running for 10 minutes.
4. Repeat these steps for a 10-minute
time extension. Only two consecutive
remote starts are allowed.
When you enter the vehicle after a
remote start, the key must be inserted
in the ignition and turned to the Run
position before driving.

Ultrasonic Rear Parking Assist
(if equipped)

the rear bumper to help you avoid collid-
ing with objects when parking the vehi-
cle. It operates only at speeds less than
5 mph.
The rear parking assist display is locat-
ed near the rear window. The lights on
the display provide distance information.
Low-toned continuous beeps play out of
the speakers when objects are within 23
inches (0.6 m) of the rear bumper.
To turn off the system, press the
(Rear Parking Assist) disable
button located below the climate

indicator light will illuminate when the

ment cluster.

(URPA) system will not activate if you
have a trailer hitch or trailer attached to
your vehicle, or a bicycle or other object
is hanging out of your vehicle. The sys-
tem may also be disabled if dirt, snow or
ice builds up on the sensors.

Maximizing Fuel Economy
Your driving behavior is a big contributor
to your vehicle’s fuel economy.
Modifying your driving habits will
improve your fuel mileage. Here are
several fuel-saving tips:
• Combine short trips to minimize cold
engine starts, which reduce fuel
economy.
• Avoid quick starts and stops.
Accelerate moderately and drive at a
steady speed.
• Anticipate traffic flow and brake mod-
erately or coast.
• Use the air conditioning and defrost
modes only when necessary.
• Minimize electrical accessory opera-
tion by turning off items such as the
rear defogger and heated seats when
they are not needed.
• Use the remote start feature sparing-
ly. This feature turns the engine on,
consuming fuel at idle.
• Do not warm up the engine by idling.
Even on the coldest days, driving will
help the engine warm up faster.
• Selecting the AUTO feature on 4WD
models will be less economical than
2WD.
• Unload unnecessary cargo to reduce
the amount of weight in the vehicle.
• Regularly check and maintain proper
tire pressure.
• Maintain your vehicle. Regular main-
tenance will keep your vehicle run-
ning cleaner and more efficiently.
