on downgrades. Transmission
operates in gears 1-2.
1 - LowUse 1 (Low) to provide
maximum engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
D(Overdrive). Selecting 1 (Low)
at higher speeds causes a shift to 2
(Second), and will shift to 1 (Low)
after vehicle decelerates to the
proper speed.
Brake-shift interlock
This vehicle is equipped with a
brake-shift interlock feature that
prevents the gearshift from being
moved from P unless the brake
pedal is depressed.
If you cannot move the gearshift
out of P with the brake pedal
depressed:
1. Apply the parking brake.
2. Turn ignition key to LOCK, then
remove the key.
3. Insert the key and turn to OFF.
4. Apply brake pedal and shift to N
(Neutral).
5. Start the vehicle.
If it is necessary to use the above
procedure to move the gearshift, it
is possible that a fuse has blown
and the vehicle's brakelamps may
not be operating properly. Refer to
Fuses and relaysin theRoadside
emergencieschapter.

that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
All rear axle lubricants must be
replaced every 160,000 km
(100,000 miles) or if the axle has
been submerged in water.
Otherwise, check the lubrication of
the rear axle according to the
intervals in theService Guide.
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
hill before driving over the crest.
When climbing a steep hill, start in
a lower gear rather than
downshifting to a lower gear from
a higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of
stalling.
When descending a steep hill avoid
sudden braking. Rapid pumping of
the brake pedal will help slow the
vehicle and still maintain steering
control.
When speed control is on and you
are driving uphill, your vehicle
speed may drop considerably,
especially if you are carrying a
Driving
105

heavy load. If vehicle speed drops
more than 15 - 25 km/h (8 - 14
mph) the speed control will cancel
automatically. Resume speed with
accelerator pedal.
If speed control cancels after
climbing the hill, reset speed by
pressing and holding the SET
ACCEL button or returning to
previous speed by pressing the
RESUME button (to resume
speeds over 50 km/h [30 mph]).
Automatic transmissions may shift
frequently while driving up on
steep grades. Eliminate frequent
shifting by shifting out of
D(Overdrive) into D (Drive).
Driving on snow and ice
An AWD vehicle has advantages
over two-wheel drive vehicles in
snow and ice but can skid like any
other vehicle.
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.
If the vehicle is stuck, shift the
transmission in a steady motion
