New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it
will perform better in the long
run
if you follow these guidelines:
0 Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
0 Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
See “Towing
a Trailer” in the Index for
more information.

Automatic Transmission Operation
Your automatic transmission may have a shift lever
located
on the console between the seats or on the
steering column.
There are several different positions for
YOLK shift lever.
If your vehicle is equipped with a column shift lever. it
features an electronic shift position indicator within the
instrument cluster. This display must be powered
anytime the
shift lever is capable of being moved out of-’
the PARK (P) position. This means that if your key is in
the OFF position, but not locked, there will be a snnall
current drain on your battery which could discharge
your battery over a period of time. If you need to leave
your key
in the ignition in the OFF position for an
extended period, it is recommended that you disconnect
the battery cable from the battery to prevent discharging
your battery.
PARK (P): This locks your rear wheels. It’s the best
position to use when
YOLI start your engine because yo~~r
vehicle can’t move easily. 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.
Don’t 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 won’t move, even when you’re on fairly
level ground, always set your parking brake and
nwve the shift lever to
PARK (P).
If you have four-wheel drive, your vehicle will
be free to roll
-- even if your shift lever is
in
PARK (P) -- if your transfer case is in
NEUTRAL (N). So, be sure the transfer case is in
a drive gear, two-wheel high
(2HI) or four-wheel
high
(4HI) or four-wheel low (4LO) -- not in
NEUTRAL (N). See “Shifting Into PARK (P)” in
the Index.
If you’re pulling a trailer, see “Towing
a Trailer” in the Index.

a trailer, carrying a heavy load. driving on
steep hills, or for off-road driving. Select DRIVE
(D)
when operating the vehicle under any of these conditions.
DRIVE (D): This position is also used for normal
driving, however
it offers Inore power and lower fuel
economy than AUTOMATIC OVERDRIVE
(@). You
should use DRIVE (D) when towing a trailer, carrying a
heavy load, driving on steep hills or winding roads or
for off-road driving.
SECOND (2): This position gives you more power but
lower
fuel economy. You can use SECOND (2) on hills.

mountain roads, but then you would also want to use
your brakes off and on. You

also LIS~ SECOND (2) for starting your vehicle
from
a stop on slippery road surfaces.
FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use
it on very steep hills, or in deep snow or mud. If the
selector lever
is put in FIRST (1) while the vehicle is
moving forward. the transmission won’t shift into
FIRST
( I) until thc vehicle is going slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into

Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if
ever have to, here are some things to know.
Idling the engine with the air system control
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO -- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard.
