2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
atrailer,loadfromyour
trailer will be transferred to
your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”

Example 1
1. Vehicle Capacity Weight forExample 1 = (453 kg)(1,000 lb)
2. Subtract Occupant Weight@68kg(150lb)◊2=136 kg (300 lb)
3. Available Occupant andCargo Weight = 317 kg(700 lb)

New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
.Keep the vehicle speed at88 km/h (55 mph) or less forthe first 805 km (500 mi).
.Do not drive at any oneconstant speed, fast or slow,for the first 805 km (500 mi).Do not make full-throttlestarts. Avoid downshifting tobrake or slow the vehicle.
.Avoid making hard stops forthe first 322 km (200 mi) orso. During this time the newbrake linings are not yetbroken in. Hard stops withnew linings can mean

premature wear and earlierreplacement. Follow thisbreaking-in guideline everytime you get new brakelinings.
.Do not tow a trailer duringbreak-in. SeeTr a i l e r To w i n g0318for the trailer towingcapabilities of the vehicleand more information.
Following break-in, engine speed
and load can be gradually
increased.

Shifting Into Park
{Warning
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. With four-wheel drive,
if the transfer case is in
N(Neutral), the vehicle will be
free to roll, even if the shift lever
is in P (Park). Be sure the transfer
case is in a drive gear. If towing a
trailer, seeDriving Characteristics
and Towing Tips0315.

1. Hold the brake pedal down,then set the parking brake.
SeeParking Brake0293.
2. Move the shift lever into theP(Park) position by pulling theshift lever toward you andmoving it up as far as it will go.
3. Be sure the transfer case (ifequipped) is in a drivegear—not in N (Neutral).
4. Turn the ignition key toLOCK/OFF.
5. Remove the key and take itwith you. If you can leave thevehicle with the ignition key inyour hand, the vehicle is inP(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
(Continued)
Warning (Continued)
if the shift lever is not fully in
P(Park) with the parking brake
firmly set.
If you have four-wheel drive and
the transfer case is in N (Neutral),
the vehicle will be free to roll,
even if the shift lever is in
P(Park). So be sure the transfer
case is in a drive gear—not in
N(Neutral).
And, if you leave the 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 unless you have to.
If you have to leave the vehicle withthe engine running, be sure thevehicle is in P (Park) and theparking brake is firmly set beforeyou leave it. After you move the shiftlever into P (Park), hold the regularbrake pedal down. Then, see if youcan move the shift lever away fromP(Park) without first pulling it toward
you. If you can, it means that theshift lever was not fully locked intoP(Park).
Torque Lock
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle may put too much force onthe parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave the driverseat. To find out how, seeShiftingInto Park0273.
When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.
If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. You will then beable to pull the shift lever out ofP(Park).

.Prevent ignition key removalunless the shift lever is inP(Park).
.Prevent movement of the shiftlever out of P (Park), unless theignition is in ON/RUN and theregular brake pedal is applied.
The shift lock release is alwaysfunctional except in the case of anuncharged or low voltage (less than9volt) battery.
If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. SeeJump Starting - NorthAmerica0432.
To s h i f t o u t o f P ( P a r k ) :
1. Apply the brake pedal.
2. Move the shift lever to thedesired position.
If you still are unable to shift out ofP(Park):
1. Ease the pressure on the shiftlever.
2. While holding down the brakepedal, press the shift lever allthe way into P (Park).
3. Move the shift lever to thedesired position.
If you are still having a problemshifting, then have the vehicleserviced soon.
This vehicle may have the SafetyBelt Assurance System, which mayprevent the vehicle from shifting outof P (Park). SeeSafety BeltMessages0155.
Parking (Manual

speed when shifting the vehicle.
D:This position is for normaldriving. It provides the best fueleconomy. If you need more powerfor passing, and you are:
.Going less than about 55 km/h(35 mph), push the acceleratorpedal about halfway down.
.Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.
By doing this, the vehicle shiftsdown to the next gear and hasmore power.

If equipped, the accelerator pedalprovides an additional downshiftafter pressing through the kickdownfeature.
It requires extra pedal pressure nearthe end of its travel to engage.
Manual Mode
Range Selection Mode
If equipped, Range Selection Modehelps control the vehicle'stransmission and vehicle speedwhile driving downhill or towing atrailer by letting you select a desiredrange of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toL(ManualMode).
2. Press the plus/minus buttonson the shift lever to select thedesired range of gears forcurrent driving conditions.
With an 8-speed automatictransmission, hold the plus/minusbuttons on the shift lever to selectthe highest or lowest rangeavailable for the current vehiclespeed.
When the shift lever is moved fromD(Drive) to L(Manual Mode), anumber displays next to the L,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in L (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when L5 is selected,1(First) through 5(Fifth) gears areautomatically shifted by thetransmission, but 6 (Sixth) cannot beused until the plus/minus button onthe shift lever is used to change tothe range.
