How long should you keep the block heater plugged in? The answer depends
on the weather, the kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact a General Motors
dealer
in the area where you’ll be parking your vehicle. The dealer can give
you the best advice
for that particular area.

Shift Light
1 K2317
If you have a manual transmission, you have a SHIFT light. This light will
show you when to shift to the next higher gear for best fuel\
economy.
When this light comes on, you can shift to the next higher g\
ear
if weather,
road and traffic conditions let you.
For the best fuel economy, accelerate
slowly and shift when the light comes on.
While you accelerate, it
is normal for the light to go on and off if you quickly
change the position
of the accelerator. Ignore the SHIFT light when you
downshift.
Four-wheel Drive Vehicles Only: If your vehicle has four-wheel drive and is
equipped with a manual transmission, disregard the shift light \
when the
transfer case is in
4 LOW.
Locking Rear Axle
If you have this feature, your rear axle can give you additional \
traction on
snow, mud ice, sand or gravel. It works like a standard axle \
most of the
time, but when one of the rear wheels has no traction and the other one
does, the locking feature will allow the wheel with traction t\
o move the
vehicle.

Features & Controls
Torque Lock
The parking brake should be set first whenever leaving the dri\
ver’s seat. If
you are parked on a hill and the transmission is placed in P (Park) before
the parking brake is set, the weight of the vehicle may put too much force
on the parking pawl in the transmission. It may be difficult to pull the selector
lever
out of P (Park). This is called “torque lock.” To prevent this, the parking
brake should be set
BEFORE moving the selector lever to P (Park).
When preparing to move the vehicle, the selector lever should be moved out
of P (Park) BEFORE releasing the parking brake. Set the parking brake first,
then release the transmission from
P (Park), even on level surfaces.
If “torque lock” does occur, you may have to have another vehicle nudge
your vehicle uphill
a little to take some of the pressure off the transmission
while you pull the selector lever out of
P (Park).
Shifting lnto P (Park) (Automatic Transmission Models Only)
It can be dangerous to get out of your vehicle if the shift lever is not I
A fully in P (Park) with the parking brake firmly set. Your vehicle can
roll.
If you have left the engine running, the vehicle can move suddenl\
y.
You or others could be injured.
To be sure your vehicle won’t move,
when you’re on fairly level ground, use the steps that foll\
ow.
If you have four-wheel drive, and your transfer case is in N (Neutral), I
your vehicle will be free to roll-even if your shift lever is in P
(Park). So, be sure the transfer case is in a drive gear-not in N
(Neutral).
If you are parking on a hill, or if you’re pulling a trailer, also see
I “Parking on Hills” or “Towing a Trailer” in the Index. I
