Performance and
Maintenance
Driving for Better Fuel
Economy
Economical Driving
How you drive, where you drive and
when you drive all affect fuel
economy.
For diesel vehicles, driving too fast,
driving so slowly that the engine
knocks, driving with the exhaust
brake switched on all the time, and
frequently using the exhaust brake
to adjust your speed can lead to
poor fuel economy.
Drive at a constant speed as much
as possible. When accelerating,
increase your speed gently and
slowly, and up-shift early.
Maintain a constant cruising speed,
as traffic allows, and avoid sudden
stops. Frequent short trips, excessive
idling and use of the air conditioner
in cool weather when "Vent" would
provide adequate comfort, can all
lead to decreased fuel economy.
Warming up the engine for longer
than necessary, driving with the
vehicle overloaded and revving the
engine are a waste of fuel.
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.
The careful attention you give your
vehicle, as far as maintenance is
concerned, will also help fuel
economy.
Protection of Engine against
Overcooling
Overcooling of the engine not only
accelerates wear of the vital engine
parts but also hurts fuel economy.

If windshield washer fluid does not
come out, release the windshield
washer switch immediately.
Otherwise the motor may seize up.
Do not hold the switch pressed for
more than 30 seconds. Otherwise,
the washer pump may sustain
damage.
Check the washer fluid level
regularly. Do it often when the
weather is bad.
Use a good quality windshield
antifreeze to help prevent freezing
damage, and for better cleaning.
When the vehicle is used in a
cold-climate region or during the
winter:
.Use washer fluid with
appropriate concentration for the
season to prevent frozen fluid. .
Fill the washer fluid reservoir
only 3/4 full to allow for
expansion if the temperature
should fall low enough to freeze
the solution.
See Washer Fluid 0274 for
information on filling the windshield
washer fluid reservoir.
Power Outlets
You can plug in auxiliary electrical
equipment. Just flip the outlet cover
open from the left edge of the cover
and follow the proper installation
instructions that are included with
any electrical equipment you install. These circuits are protected by a
fuse and have maximum current
loads.
When using accessory power
outlets, total maximum electrical
load must not exceed 120W. Always
turn off any electrical equipment
when not in use.
Leaving electrical equipment on for
extended periods will drain your
battery.

276 Vehicle Care
Follow the recommendations for
brake checks in the Maintenance
Schedule.
GM replacement brake lining
material is recommended for this
vehicle to maintain the balance
between front and rear brake
performance. GM replacement
brake parts have been carefully
selected to provide the proper brake
balance for purposes of both
stopping distance and controllability
over the full range of operating
conditions. Installation of front or
rear brake lining material with
performance different from that of
the replacement parts
recommended for this vehicle can
change the intended brake balance
of this vehicle.
Checking the Brake Electric
Vacuum Pump (4500HD/
4500XD Series)
1. Turn the engine control switchto the "ON" position (do not
start the engine), and press the
brake pedal several times. 2. Check for the noisy sound of
the electric vacuum pump
inside the instrument panel at
the same time as vacuum
warning buzzer sound, and
check that the brake low
vacuum warning light
comes on.
3. Then, start the engine. The main vacuum pump driven by
the engine will start running.
If the electric vacuum pump
operation (noisy sound) and
the vacuum warning buzzer
stop, and the brake low
vacuum warning light goes off
thereafter, the operation is
normal.
4. If you cannot hear the noisy sound or the noisy sound stays
on all the time, have the
vehicle inspected by the
nearest dealer immediately.Hydraulic Brake Booster (HBB)
The 5500HD, 5500XD models are
equipped with a HBB system. HBB
is a brake booster device that utilizes hydraulic pressure from the
HBB pump integral with the power
steering pump.
If the brake booster warning light
comes on or a warning buzzer
continues to sound, there may be a
problem with the HBB.
If this warning light comes on while
driving, immediately stop your
vehicle at a safe place well clear of
traffic and promptly contact the
nearest dealer for inspection.
Hydraulic brake booster (HBB)
characteristics
In the 5500HD, 5500XD models, an
unusual sound from under the
instrument panel may be heard from
the hydraulic system while brakes
are used. It does not mean trouble.
It is not a sign of malfunction.
If you pump the brakes with the
engine off, a squeaking sound can
be heard. This comes from the
auxiliary accumulator. It is not a
malfunction. With the engine
running, a similar sound can be
heard during sudden braking.
