won’t
move, wh’en you’re on fairly level ground, always set your
parking brake and move the
shift lever to P (Park).
If you have four-wheel drive, your vehicle will be free to roll-even if
your shift lever is in P (Park)-if your transfer case is in N (Neutral).
So, be sure the transfer case is
in a drive gear-not N (Neutral).
See “Shifting Into Park” in the Index. If you are parking on a hill, or
if you’re pulling a trailer, also see “Parking on Hills’’ or ‘Towing a
Trailer”
in the Index.
R (Reverse)
Use this gear
to back up.
I NOTICE
I!
Shifting to R (Reverse) while your vehicle is moving forward could damage
jour transmission. Shift to R (Reverse) only after your vehicle is stopped.
To rock your vehicle back and forth
to get out of snow, ice or sand without
damaging your transmission, see “If You’re Stuck: In Sand, Mud, Ice or
Snow” in the Index.
N (Neutral)
In this setting, your engine doesn’t connect with the wheels.
To restart when
you’re already moving, use
N (Neutral) only. Also, use N when your vehicle is
being towed.
I CAUTION
Shifting out of P (Park) or N (Neutral) while your engine is “racing”
(run’ning at
high speed) is dangerous. Unless your foot is firmly on
the brake pedal, your vehicle could move very rapidly. You could lose
control and hit people or objects. Don’t shift out of P (Park) or N
(Neutral) while your engine is racing. I

NOTICE
Damage to your transmission caused by shifting out of P (Park) or N
{Neutral) with the engine racing isn’t covered by your warranty.
OD (Automatic Overdrive)
This position is for normal driving.
If you need more power for passing, and
vou’re:
- Going less than about 35 mph (56 km/h), push your accelerator
pedal about halfway down
- Going about 35 mph (56 km/h) or more, push the accelerator all the
way down
You’ll shift down to the next gear and have more power.
OD should not be used when towing a trailer, carrying a heavy load, driving
on steep hills, or for off-road driving. Select
D (third gear) when operating the
vehicle under any of these conditions.
D (Third Gear)
This is like
OD, but you never go into Overdrive. You should use D when
towing a trailer, carrying a heavy load, driving on steep hills, or for off-road
driving.
2 (Second Gear)
This position gives you more power but lower fuel economy. You can use
2
on hills. It can help control your speed as you go down steep mountain
roads, but then you would also want
to use your brakes off and on.
If you manually select 2, the transmission will drive in second gear. You may
use this feature for reducing torque to the rear wheels when you are trying to
start your vehicle from a stop on slippery road surfaces.
1 (First Gear)
This position gives you even more power (but lower fuel economy) than
2.
You can use it on very steep hills, or in deep snow or mud. If the selector
lever is put
in 1, the transmission won’t shift into first gear until the vehicle is
going
‘slowly enough.

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).

lnsfrument Cluster
Your instrument cluster is designed to let you know at a glance how your.
vehicle is running. You'll know
how fast you're going, about how much fuel
you have,
and many other things you'll need to know to drive safely and
economically.
Tachometer Cluster
If you have the tachometer cluster, it looks slightly different but will tell you
everything the standard cluster does, in addition to displaying the vehicles
engine revolutions per minute (rpm).
Speedometer and Odometer

K2322
Your speedometer lets you see your speed in both miles per hour (mph) and
kilometers per hour (km/h). Your odometer shows how far your vehicle
has
been driven, in either miles (used in the U.S.) or kilometers (used in
Canada).
Tamper Resistant Odometer
Your odometer is tamper-resistant, The odometer will show silver line\
s
between the numbers
if someone tries to turn it back.
You may wonder what happens if your vehicle needs a new odome\
ter installed.
If the new one can be set to the mileage total of the old odometer,
tien
it must be. But if it can't, then it's set at zero, and a label must be put
on the driver's
door to show the old mileage reading when the new odometer
was installed.
