Hummer 2006 H3 Automobile User Manual


 
There are several different positions for your shift lever.
PARK (P): This position locks your rear wheels. It is
the best position to use when you start the engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, always
set your parking brake and move the shift
lever to PARK (P). See Shifting Into Park (P)
(Automatic Transmission) on page 2-28.
If you are pulling a trailer, see Towing a
Trailer on page 4-58.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in ON. If you cannot
shift out of PARK (P), ease pressure on the shift
lever by pushing the shift lever all the way into PARK (P)
as you maintain brake application. Then move the
shift lever into the gear you want. See Shifting Out of
Park (P) (Automatic Transmission) on page 2-30
REVERSE (R): Use this gear to back up.
Notice: Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
see If Your Vehicle is Stuck in Sand, Mud, Ice or
Snow on page 4-50
