Indicates vehicle information
related to recycling and other
environmental concerns will follow.
Correct vehicle usage and the
authorized disposal of waste
cleaning and lubrication materials
are significant steps towards
protecting the environment.
WARNINGS
Warnings provide information
which may reduce the risk of
personal injury and prevent
possible damage to others, your
vehicle and its equipment.
BREAKING-IN YOUR VEHICLE
There are no particular breaking-in
rules for your vehicle. During the
first 1 600 km (1 000 miles) of
driving, vary speeds frequently.
This is necessary to give the
moving parts a chance to break in.
If possible, you should avoid full
use of the brakes for the first
1 600 km (1 000 miles).

Introduction

To set a speed
²Press SET ACC/SET ACCEL.
For speed control to operate,
the speed control must be ON
and the vehicle speed must be
greater than 48 km/h (30 mph).
If you drive up or down a steep
hill, your vehicle speed may vary
momentarily slower or faster than
the set speed. This is normal.
Speed control cannot reduce the
vehicle speed if it increases above
the set speed on a downhill. If
your vehicle speed is faster than
the set speed while driving on a
downhill, you may want to shift to
the next lower gear or apply the
brakes to reduce your vehicle
speed.
If your vehicle slows down more
than 16 km/h (10 mph) below your
set speed on an uphill, your speed
control will disengage. This is
normal. Pressing
RES/RSM/RESUME will re-engage
it.
Do not use the speed
control in heavy traffic or
on roads that are winding,
slippery, or unpaved.

combination lap and shoulder
belts. The front and rear seat
passenger outboard safety belts
have two types of locking modes
described below:
Vehicle sensitive mode
The vehicle sensitive mode is the
normal retractor mode, allowing
free shoulder belt length
adjustment to your movements and
locking in response to vehicle
movement. For example, if the
driver brakes suddenly or turns a
corner sharply, or the vehicle
receives an impact of 8 km/h (5
mph) or more, the combination
safety belts will lock to help
reduce forward movement of the
driver and passengers.
The front seat belt system can also
be made to lock manually by
quickly pulling on the shoulder
belt. Rear seat belts (if equipped)
cannot be made to lock up by
pulling quickly on the belt.
Automatic locking mode
In this mode, the shoulder belt is
automatically pre-locked. The belt
will still retract to remove any
slack in the shoulder belt.
The automatic locking mode is not
available on the driver safety belt.
When to use the automatic
locking mode

desired.

BRAKES
Your brakes are self-adjusting.
Refer to the ªService Guideº for
scheduled maintenance.
Occasional brake noise is normal
and often does not indicate a
performance concern with the
vehicle's brake system. In normal
operation, automotive brake
systems may emit occasional or
intermittent squeal or groan noises
when the brakes are applied. Such
noises are usually heard during the
first few brake applications in the
morning; however, they may be
heard at any time while braking
and can be aggravated by
environmental conditions such as
cold, heat, moisture, road dust, salt
or mud. If a ªmetal-to-metal,º
ªcontinuous grindingº or
ªcontinuous squealº sound is
present while braking, the brake
linings may be worn-out and
should be inspected by a qualified
service technician.
Anti-lock brake system (ABS)
On vehicles equipped with an
anti-lock braking system (ABS), a
noise from the hydraulic pump
motor and pulsation in the pedal
may be observed during ABS
braking events. Pedal pulsation
coupled with noise while braking
under panic conditions or on loose
gravel, bumps, wet or snowy roads
is normal and indicates proper
functioning of the vehicle's
anti-lock brake system. If the
vehicle has continuous vibration or
Driving

shudder while braking, felt mainly
in the steering wheel, the vehicle
most likely needs service.
The ABS operates by detecting the
onset of wheel lock up during
brake applications and
compensating for this tendency.
The front wheels are prevented
from locking even when the brakes
are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking.
ABS warning lamp
The
ABSwarning lamp in the
instrument cluster illuminates for
about five seconds when starting
the vehicle. If an ABS fault is
detected, the light will remain on
and your vehicle should be
serviced as soon as possible.
Normal braking is still effective
unless the BRAKE warning lamp is
also illuminated.
Using ABS
²In an emergency or when
maximum efficiency from the
ABS is required, apply
continuous full force on the
brake. The ABS will be activated
immediately, thus allowing you
to retain full steering control of
your vehicle and, providing

The parking brake is not designed
to stop a moving vehicle. However,
if the normal brakes fail, the
parking brake can be used to stop
your vehicle in an emergency.
Since the parking brake applies
only the rear brakes, the vehicle's
stopping distance will be adversely
affected.
Pull the release lever to release
the brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
TRACTION-LOK AXLE (IF
EQUIPPED)
This axle provides added traction
on slippery surfaces, particularly
when one wheel is on a poor
traction surface. Under normal
conditions, the Traction-Lok axle
functions like a standard rear axle.
Extended use of other than the
manufacturer's specified size tires
on a Traction-Lok rear axle could
result in a permanent reduction in
effectiveness. This loss of
effectiveness does not affect

Once through water, always try the
brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes.
Drying can be improved by moving
your vehicle slowly while applying
light pressure on the brake pedal.
After driving through mud, clean
off residue stuck to rotating
driveshafts and tires. Excess mud
stuck on tires and rotating
driveshafts causes an imbalance
that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
Water intrusion into the
transmission may damage
the transmission.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Driving on hill or slope terrain
When driving on a hill, avoid
driving crosswise or turning on
steep slopes. You could lose
traction and slip sideways. Drive
straight up, straight down or avoid
the hill completely. Know the
conditions on the other side of a
Driving

Avoid sudden applications of
power and quick changes of
direction on snow and ice. Apply
the accelerator slowly and steadily
when starting from a full stop.
When braking, apply the brakes as
you normally would. In order to
allow the anti-lock brake system
(ABS) to operate properly, keep
steady pressure on the brake
pedal.
Allow more stopping distance and
drive slower than usual. Consider
using one of the lower gears.
VEHICLE LOADING
Before loading a vehicle, familiarize
yourself with the following terms:
²Base Curb Weight: Weight of
the vehicle including any
standard equipment, fluids,
lubricants, etc. It does not
include passengers or
aftermarket equipment.
²Payload: Combined maximum
allowable weight of cargo,
passengers and optional
equipment. The payload equals
the gross vehicle weight rating
minus base curb weight.
²GVW (Gross Vehicle Weight):
Base curb weight plus payload
weight. The GVW is not a limit
or a specification.
²GVWR (Gross Vehicle Weight
Rating): Maximum total weight
of the base vehicle, passengers,
optional equipment and cargo.
The GVWR is specific to each
