Downloaded from www.Manualslib.com manuals search engine Break·ln Schedule
See the new vehicle break-in instructions in this manual. Also, we
recommended you drive your new vehicle for 500 miles (600 kilometers) before
trailer towing . AI the end of this 500 mile (600 kilometer) break-in period, avoid
speeds over 50 mph (80 km/h) and full throttle starts during the first 500 miles (800 kilometers) of trailer towing.
CAUTIONS:
BRAKES-To help avoid personal injury due 10 poor braking action:
• Trailer brakes of adequate size are required on Irailers more Ihan 450 kilograms (1,000 pounds) loaded weight.
• If you use trailer brakes with this vehicle , follow the installation and balance
instructions of the trailer brake maker.
• Do not tap into the vehicle's brake system tl the trailer brake system uses
more than 0.3 cubic centimeter (0.02 cubic inch) of fluid from the vehitle's
master cylinder. In this case, the vehicle brake fluid capacity will not be enough to operate both the vehicle and trailer brakes under all kinds of
use.
• All brake fluid parts must be able to stand 20 650 kPa (3,000 psi) .. The
brake fluid tap must be made to the master cylinder port supplying fluid to
the rear brakes. Copper tubing is subject to fatigue failure and must not be
used.
• Before going down a steep or long grade, reduce speed. and shiftlhe transmission into a lower gear 10 help control too' long or too often . This
could cause
Ihe brakes 10 overheal and reduce brake ef\ectiveness. .
HITCHES2T6 HeIP'avoid pe,sona/ ,jQiYry.Que 10 sway caused by such things as
crosswinds , big trucks passing or roact roughness, or due to separalion of the
trailer :
• A properly installed and adjusted (1) frame mounted, weight-distributing
hitch and (2) sway control with enough capacity are required for trailers
more than 900 kilograms
(2,000 pounds) loaded weight.
• If your vehicle has air shocks, keep them at a minimum pressure of 70 to 105 kPa (10 to 15 psi) when installing, adjusting or towing with a weight­
distributing hitch.
• Keep the trailer tongue load at 10"10 of the loaded trailer \'feight for dead­
weight hitches, and 12"10 for weight-distribuling hitches. Tongue loads can be adjusted by proper distribution of the load in the trailer. This can be
checked by
weighjng separately the loaded trailer and then the tongue .
• Do not use axle-mounted hitches. They can damage the axle hOuSing, wheel bearings, wheels or lires.
•
When you remove a trailer hitch, be sure to seal any mounting holes in the
bocjy. This will help prevent entry of exhaust fumes, dirt or water. (See
"Engine Exhaust Gas Caution (Carbon Monoxide)" at the beginning of "Starting and Operating," Section 2 of this manual.)

"InCase of Emergency," Section 3 01 this manual.
Long Uphill Grades
When goingup,long grades ; you can reduce the chance of engine overheating
by dOwnshifting the transinission to a
Jower'gear range and reducing speeds to
'" '4S mph (70 km /h) or below . '. " " ,-,-."." .. ,. '
Transmission
See the method for checking the transmission fluid level in "Service and
"'~!!illl£<;': Section S of thismanuaJ.
Parking
You should not park vehicles with trailers on a grade (hill); However, If
you must park on a 'grade, these ste,PS }l1ust be fallowed:
1. Apply theregular .brakes . ,'\' y .
2, . Have someone place wheel chocks under the trailer wheels .
3. When the wheel cho cks are in place, release the regular brakes until, the
c hocks absorb the load. .
4 . Apply
the parking brake.
S . Shift the transmission to
"P"(l'ark) .
If the veh icle is parked on a .gr ad e, don 't Shift the transmission to "P "(Park )
until
the trailer wheels are chocked and tOO parking brake is set If you dO, the weight of the vehicle and trailer may put'somuch force on the parking pawl in
the transmission that it·may be hard to Shift out of "P "(Park) .

Downloaded from www.Manualslib.com manuals search engine Tire Inflation
Underinflation not only causes needless wear 01 the tires, but can also waste ' fuel. It's a good idea to check tire pressures often and, fO( the best fuel
eccnomy, keep your tires inflated to the highest pressures shown on the Tire
Placard on the left front door of your vehicle .
Wheel Alignment
Improper toe alignment will cause the tires to roll at an angle, which will result in faster tire wear. It takes' power to overcome this improper alignment which.
in turn, wastes fuel.
STEERING COLUMN CONTROLS
ANTI-THEFT STEERING COLUMN LOCK
The anti-theft lock (ignition) on the right side of the steering column has five
-""'positions: .
• Accessory-You can use SO the top of the key toward you.
• Lock -Normal parking position. It locks the ignition and prevents normal use
of the steering
wheel and shift controls. The ignition key cannot be turned
to "Lock" and removed until the shift lever is moved to "P"(Park).
• Off-You
can turn off the engine without locking the steering wheel and shift controls.
• Run-Normal operating position.
• Start-Cranks the engine.
If you have trouble turning the key to uniock the ignition, first be sure the key is
pushed in
all the way . Then , try to turn the steering wheel as hard as you can
in the direction the
wheels are turned. At the same time, turn the ignition key
with as much effort as you can apply with your hand; Do not try to use a tool of
any kind to
apply more force on the lock knob, as this could break the knob .
NOncE: Do not drive through, idle or park your vehicle over combustible marla Is, .uch •• grass or leaves. They could touch the hot eJlhauat .ystem .-.cIlgnite.

•
Turn the key to "Lock ."
•
Remove the key (the · buzzer is designed to remind you).
• Lock all doors .
TURN SIGNAL AND HEADLIGHT BEAM LEVER
The turn signal lever on the left side of the steering column also controls
headlight low-beam and high-beam and the optional Cruise Control. (For Cruise Control operation, see page 2-12.)
• Turn Signal -Move the lever up to the second stop to signal a right turn.
Move it down to the second stop to signal a left turn. When the turn is
completed, the signal will cancel and the lever will return to horizontal.
• Lane Change Signal -In some turns, such as changing lanes, the steering wheel is not turned far enough to cancel the turn signal . ·For convenience,
you can flash the turn signal by moving the lever part way (to the first stop)
and holding it there. The lever will return to horizontal when you release it.

A green light on the instrument panel is designed to flash to tell, you that the
lront and rear turn signal lights are working . If the light stays on, but does not
flash, check for burned-out turn signal bulbs.
If the green light does not come on when you move the lever, check the fuse and indicator bulb. However, if
you ordered a traiter towing option in which extra wiring was added to attach
the
trailer lighting, a different type'of flasher was installed. In tliis case, the
green light will continue to flash even if a turn signal bulb bUrns out. Therefore ,
you must
regularly look at the front and rear turn signal lights to be sure they
are working.
• Headlight Beam Changer -With the headlights on, pull the lever toward
you until you hear a click, then release it. The lights will change from Iow­
beamto high-beam or from high-beam to low-beam . When the hig~-beams
are on, a blue light will appear on the instrument panel.
CORNERING UGHTS
The front fender cornering lights operate in conjunction with the turn signals.
When the turn signal is operating in either direction, and the headlights or
parking
lights are on, the corresponding cornering light emits a steady
sideward beam to provide additional illumination .

1 . If you tried the cold ef1gine starting procedure and the engine did not start,
then
fully depress and release the acceleraior pedal several times. Take
your foot off the
pedal and crank the engine by turning the key to "Start."
2. If you tried the warm engine starting procedure (or the eold engine
procedure
and Step 1 above) , and the ef1gine still does not start, press the
accelerator pedal to the floor and hold it there while cranking the engine.
This should clear the engine if it is flooded. .
3. If the engine has been flooded with too much fuel, It may start to run but not have enough power to keep running, In that case, continue
cranking
with 11M! accelerator pedal aU the way to the 1100< until the
engine clears
~self of excess gascHne and runs smoothly. (But, do not
crank more than 15 seconds atatime Or you could damage the starter.)

usecare,,¥t\1 range, whe;;1eitli'er'plt5()l!W_wIl~elS8fe..traveling over a slippery surface.
Sudden acceleration or engine braking action (due to
shilling to a lower ge,n)
could cause one or both drive wheels to spin or skid and the rear of the vehicle
to slide sideways on the crowned · surface.of a road or in a turn, Normal skid
correction is
called for at these times.
AUTOMATIC TRANSMISSIONS
Automatic transmissions replace the standard cMch and transmission. After
starting
the engine with the selector lever in"P" (Park) or "N" (Neutral)
position, select the range desired
(see table) and depress . the accelerator. A
gradual start
with a steady increase in accelerator pressure will result in best
possible fuel economy . Rapid acceleration for fast startS will result in greater
fuel consumption. ..
AutomatiC transmission shift quadrants of all GM vehicles continue the uniform
sequence of
selector positions. Shift indiCators are arranged with "P"(Park)
position atone end, followed in sequElf)ce by "R"(Reverse). "N"(Neutral) and
the forward
driving , ranges .. All .automatic transmiSsions are equipped with a
starter safety switch'
design'ld to permit starting the ef1gine only when the transmission selector is in the "P"(Park) or"N"(Neutral) position. For
additional engine braking
eflact, as SOmetimes needed in mountainous driving,
place thetransmi$Sion in an intermediate or low range.

Your automatic transmission may have either a clutch-type torque converter or an open,type torque COnverter . Both offer the quality performance associated
with General Motors products.
·~-so·_equipped, the converter clutch is designed to engage when the vehicle reaches a st)lady speed of about 25 mph (40 km/h) or, higher depending on
the particular model. When engagEid, the' clutch providE.s a direct connection
between the engine and the drive
wheels. This direct connection allows for
more efficient operation of the transmission and thereby helps contribute to
improved
fuel economy. With the ClUtch-type converter, you may notice some
operational d,ifferences · compared to other. automatic transmissions equipped vehicles. When the clutch engages , for example, you may notice what feels
like
an extra transmission shift. Also, on occasion, you may feeLcertain
incidental engine pulsations in the 30 to 50 mph (50 to' 80 km/h) range. This feel is similar to that so.rnetimes experienced in a manual transmisSK>n
equipped vehicle. In addrtion, when the accelerator pedal is released abruptly,
you may feel a slight impulse before the clutch disengages.
These conditions are normal. They have no adverse effect on your vehicle and do not indicate the need for repairs . .
Notice
The following practices could result in autoinatic transmission failure:
• Shifting between forWard and reverse driving' range while operati/lg the
engine at high speed or heavy throttle, such as when the driving wheels
are on snow Of ice--commonly called "rocking." (See the corre<:t method
for
"rocking" vehiCle under "Freeing Vehicle from Sand, Mud, Snow or Ice" in "In Case of Emergency," Sectiorl.'3 of this manual.)
•
Shifting to "R"(Reverse) or any forward range while operating the engine
at high speed in "N"(Neutral} or "P"(Park).
• ·Shifting to "P"(Park) while the vehicle wheels are still turning.

LIMITED-SLIP REAR AXLE
On vehicles that have it. the optional limited-slip rear axle can give added
traction on snow, ice, mud, sand, gravel, etc. Normally , the limited-slip axle
unit works like a standard axle. However, when either drive wheel meets a
slippery enough surface, and the opposite wheel is on a surface with greater traction, the ,limited-slip 'unit can continue to give driving force tathe wheel
having the greater traction,instead 01 merely spinning the wheel that has the
least traction .
Whether your
vehicle has an optional limited-slip rear axle or a standard axle, take care when speeding up or, whera shifting into a lower gear or lower gear
range , when either or both rear wheels are traveling over a slippery surface .
Sudden acceleration or engine braking action (due to shifting to a lower gear)
could cause one or both drive wheels to spinorskid and the rear 01 the vehicle to slide sideways on the crowned, ·surface of a road or in a turn. Normal skid correction and cautious driving are called for at these times.
COURTJ:SY LIGHT DELAY SYSTEM
If your vehicle is equipped with this optional feature, whenever the door is opened, then closed, on entry or exit, the dome and courtesy lights stay on for thirty seconds for convenience of driver and passengers. This presumes the
ignition is in the off position . When the ignition key is turned on. the lights will
go off. When the ignition key is turned to off, the dome and courtesy lights go
",'" of>.lor. ~.R~riod 01 fifteen seconds.
SUNROOF
The optional Sunroof is a slid ing metal panel, electrically operated. controlled
by a switch on the front center area ,Qf theroof. The ignition must be in "Run" to move the panel. " .
To' open. press the control switch rearward. To close. press it forward. The
Sunroof can
be lett partly open by releasing the control switch while you are
opening or closing the panel.
The Sunrool can be closed manually il your car has an electrical power lailure.
To do this , remoVe the small round plug in the rool (near the control switch) by pulling the plug downward with your lingers . Then insert the hex end 01 the
crank handle (supplied in your glove box) into the drive gear and turn it
clockwise to close the rool panel, and counterclockwise to open it. Remove the
crank handle and replace the plug . (See illustration.)
