ignition CHEVROLET MALIBU 2005 5.G Repair Manual

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all uid
levels and also the brakes, tires, cooling system,
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
Know how to go uphill. Drive in the highest gear
possible.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at speeds
that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car or
an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area, or winding roads. Be alert to these and take
appropriate action.

Dinghy Towing
To tow your vehicle with all four wheels on the ground,
follow these steps:
1. Position the vehicle to tow and then secure it.
2. Turn the ignition switch to off.
3. Set the parking brake.4. To prevent your battery from draining while the
vehicle is being towed, remove the following
fuse from the engine compartment fuse
block: 20 IBCM 1. See “Engine Compartment Fuse
Block” underFuses on page 5-83.
5. Turn the ignition switch to ACC.
6. Shift your transaxle to NEUTRAL (N).
7. Release the parking brake.
Remember to install the fuses once you reach your
destination. To reinstall a fuse do the following:
1. Set the parking brake.
2. Remove the key from the ignition switch.
3. Reinstall the fuse.
Notice:If you exceed 65 mph (105 km/h) while
towing your vehicle, it could be damaged. Never
exceed 65 mph (105 km/h) while towing your vehicle.
4-36

Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (−) terminal locations on
each vehicle. SeeEngine Compartment Overview
on page 5-12for more information on location.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.

Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-29.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to ON, but do
not start the engine. Without applying the regular
brake, try to move the shift lever out of PARK (P)
with normal effort. If the shift lever moves out
of PARK (P), contact your GM Goodwrench
®dealer
for service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition to OFF in each shift lever position.
The ignition should turn to OFF only when the shift
lever is in PARK (P).
The key should come out only in OFF.
Contact your GM Goodwrench
®dealer if service is
required.
