Removing the Third Row Seats
To remove a third row seat:
1. Remove the cargomanagement system,
if available and installed.
See Cargo Management
System on page 4‑3.
2. Remove anything on or under the seat.
Notice: Folding a rear seat with
the safety belts still fastened may
cause damage to the seat or the
safety belts. Always unbuckle the
safety belts and return them to
their normal stowed position
before folding a rear seat.
3. Fold the seatback down.
See “Folding the Seatback”
earlier in this section.
4. Remove the rear bolts on the floor on each side of the seat. 5. Remove the seat by tilting it
slightly upward, and then pulling
it out of the rear of the vehicle in
one motion.
6. Replace the bolts in the floor holes for storage.
Installing the Third Row Seats
To reinstall a third row seat:
1. Before installing the seat
the seatback must be folded
forward. See “Folding the
Seatback” earlier in this section.
The seats must be placed in
the proper locations to attach
correctly. The wider seat must
be installed on the driver side
and the narrower seat on the
passenger side. Remove the
bolts from the holes in the floor
before installing the seats. 2. Place the seat on the vehicle
floor so that the front seat hooks
are on the vehicle bars.
3. Reinstall the bolts, and torque to 55Y (41 lb ft). Pull up on the
seat to make sure it is locked in
place.
4. Raise the seatback to the upright position. Push and pull
on the seatback to make sure it
is locked into place.
5. Reconnect the center safety belt mini-latch to the mini-buckle.
Do not let it twist.

9-22 Driving and Operating
2. Move the shift lever into P (Park)by holding in the button on the
shift lever and pushing the shift
lever all the way toward the front
of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
(Continued)
WARNING (Continued)
vehicle with the engine running,
it could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running.
If you have to leave the vehicle
with the engine running, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
the regular brake pedal down.
Then, see if you can move the
shift lever away from P (Park)
without first pushing the button.
If you can, it means that the shift
lever was not fully locked in
P (Park).
Torque Lock
Torque lock is when the weight
of the vehicle puts too much
force on the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see “Shifting Into Park”
listed previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).

Driving and Operating 9-27
This is normal and is due to
the torque converter designed
to improve fuel economy and
performance. Use the brake to
hold the vehicle on a hill. Do not
use the accelerator pedal.
L (Low):This position gives
you access to gear ranges. This
provides more engine braking but
lower fuel economy than D (Drive).
You can use it on very steep hills,
or in deep snow or mud.
Manual Mode
Electronic Range
Select (ERS) Mode
ERS mode allows you to choose
the top-gear limit of the transmission
and the vehicle's speed while
driving down hill or towing a trailer.
The vehicle has an electronic
shift position indicator within the
instrument panel cluster. When
using the ERS Mode a number will
display next to the L, indicating the
current gear that has been selected. To use this feature:
1. Move the shift lever to L (Low).
2. Press the plus/minus button
located on the shift lever, to
increase or decrease the gear
range available.
When you shift from D (Drive) to
L (Low), the transmission will shift to
a pre-determined lower gear range.
The highest gear available for this
pre-determined range is displayed
next to the L in the DIC. See Driver
Information Center (DIC) (With DIC
Buttons) on page 5‑25 orDriver
Information Center (DIC) (Without
DIC Buttons) on page 5‑30 for more
information. The number displayed
in the DIC is the highest gear that
the transmission will be allowed
to operate in. This means that
all gears below that number are
available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle. The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive).
While in L (Low), the transmission
will prevent shifting to a lower gear
range if the engine speed is too
high. You have a brief period of
time to slow the vehicle. If vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. You must
further slow the vehicle, then press
the
−(Minus) button to the desired
lower gear range.
Automatic Engine Grade braking
is not available when the ERS is
active. It is available in D (Drive) for
both normal and Tow/Haul mode.
While using the ERS, cruise control
and the tow/haul mode can be used.
See Tow/Haul Mode following.

10-24 Vehicle Care
Brakes
This vehicle has disc brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying
the brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when
the brakes are first applied or
lightly applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in
the proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a
sign that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes —for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.

10-52 Vehicle Care
Tire Rotation
Tires should be rotated every
12 000 km (7,500 miles).
SeeScheduled Maintenance on
page 11‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like
it did when the tires were new.
The first rotation is the most
important. See Scheduled
Maintenance on page 11‑2.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
See When It Is Time for New
Tires on page 10‑53 andWheel
Replacement on page 10‑59.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in
the tire rotation.
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See Tire Pressure on
page 10‑45 andVehicle Load
Limits on page 9‑12. Reset the Tire Pressure Monitor
System. See
Tire Pressure
Monitor Operation on
page 10‑48.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
In an emergency, use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire
brush later, if needed, to get all
the rust or dirt off. See If a Tire
Goes Flat on page 10‑61.

to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2
for original equipment wheel
nut torque specifications.
Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts
in the proper sequence and to
the proper torque specification.
