2010 GMC YUKON HYBRID fuel pressure

A chime will sound if the driver door is opened while in
Auto Stop as a reminder that the ignition switch is not in
the LOCK/OFF position. Always turn the ignition switch
to LOCK/OFF and remove the key from the ignition
switch when exiting the vehicle.
Auto Start
The vehicle also has an Auto Start feature. The engine
will remain off while in Auto Stop mode until vehicle
conditions require the engine to run. The near-instant
starting of the engine from Auto Stop mode is called
Auto Start.
EV Mode
The vehicle also has an EV mode which uses only
the electric motor to move the vehicle. With light
acceleration, the vehicle will drive in EV mode.
EV mode is unavailable when the vehicle is out of fuel.
See Starting the Vehicle in the Two‐Mode Hybrid
supplement to the owner manual.
Regenerative Braking
Regenerative braking enables the electric drive motor
to operate as a generator when coasting or braking.
Energy from the moving vehicle recharges the hybrid
battery.
The hydraulic disc brakes work with the regenerative
braking to insure effective braking.
The braking system is computer controlled and blends
the regenerative braking with the conventional hydraulic
disc brakes to meet any requirements for deceleration.
Because the controller applies the hydraulic brakes
through its high pressure accumulator, you may
occasionally hear the motor driven pump when it
recharges the system. This is normal. In the event of a
controller problem, the brake pedal may be harder to
push and the stopping distance may be longer.
See Regenerative Braking, Warning Lights, Gages, and
Indicators and Driver Information Center (DIC) in the
owner manual.

Tires
Inflation - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice:
Do not let anyone tell you that
under‐inflation or over‐inflation is all right.
It is not. If your tires do not have enough air
(under‐inflation), you can get the following:
.Too much flexing
.Too much heat
.Tire overloading
.Premature or irregular wear
.Poor handling
.Reduced fuel economy
If your tires have too much air (over‐inflation),
you can get the following:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from road hazards
A vehicle specific Tire and Loading Information label is
attached to your vehicle. This label shows your
vehicle's original equipment tires and the correct
inflation pressures for your tires when they are cold.
The recommended cold tire inflation pressure, shown
on the label, is the minimum amount of air pressure
needed to support your vehicle's maximum load
carrying capacity.
For additional information regarding how much weight
your vehicle can carry, and an example of the Tire and
Loading Information label, see “Loading Your Vehicle”in
the Index of the owner manual. How you load your
vehicle affects vehicle handling and ride comfort. Never
load your vehicle with more weight than it was designed
to carry.
