Starting the Engine
If the vehicle is a Two-mode Hybrid, see the Two-modeHybrid manual for more information.
Move the shift lever to P (Park) or N (Neutral). Theengine will not start in any other position. To restart theengine when the vehicle is are already moving, useN (Neutral) only.
Notice:Do not try to shift to P (Park) if thevehicle is moving. If you do, you could damagethe transmission. Shift to P (Park) only when thevehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn theignition key to START. When the engine starts,let go of the key. The idle speed will go down asthe engine gets warm. Do not race the engineimmediately after starting it. Operate the engineand transmission gently to allow the oil to warm upand lubricate all moving parts.
The vehicle has a Computer-Controlled CrankingSystem. This feature assists in starting the engineand protects components. If the ignition key isturned to the START position, and then releasedwhen the engine begins cranking, the engine willcontinue cranking for a few seconds or until thevehicle starts. If the engine does not start and thekey is held in START for many seconds, crankingwill be stopped after 15 seconds to preventcranking motor damage. To prevent gear damage,this system also prevents cranking if the engineis already running. Engine cranking can bestopped by turning the ignition switch to theACC/ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods oftime, by returning the key to the START positionimmediately after cranking has ended, can overheatand damage the cranking motor, and drain thebattery. Wait at least 15 seconds between each try,to let the cranking motor cool down.

2. If the engine does not start after 5!10 seconds,especially in very cold weather (below 0°F or!18°C), it could be flooded with too much gasoline.Try pushing the accelerator pedal all the way to thefloor and holding it there as you hold the key inSTART for up to a maximum of 15 seconds. Wait atleast 15 seconds between each try, to allow thecranking motor to cool down. When the enginestarts, let go of the key and accelerator. If thevehicle starts briefly but then stops again, do thesame thing. This clears the extra gasoline from theengine. Do not race the engine immediately afterstarting it. Operate the engine and transmissiongently until the oil warms up and lubricates allmoving parts.
Notice:The engine is designed to work with theelectronics in the vehicle. If you add electricalparts or accessories, you could change the waythe engine operates. Before adding electricalequipment, check with your dealer/retailer. If youdo not, the engine might not perform properly.Any resulting damage would not be covered bythe vehicle warranty.
Adjustable Throttle and Brake Pedal
The vehicle has adjustable throttle and brake pedalsthat allow you change their positions.
The feature will not operate when the vehicle is inR (Reverse) or while using the cruise control.
The switch used to adjust the pedals is located on thecenter console below the climate control system.
Press the right and left arrows to move the pedals eithercloser or further from your body.
Before you start driving, fully press the brake pedal toconfirm the adjustment is right for you. While driving,make only small adjustments.
The vehicle has a memory function which allows thepedal positions to be saved and recalled. SeeMemoryFeatureso n p a g e 2!6for more information.

Driving On Grades
Reduce speed and shift to a lower gearbeforestartingdown a long or steep downgrade. If the transmission isnot shifted down, the brakes might get hot and nolonger work well.
Vehicles can tow in D (Drive). Shift the transmission toa lower gear if the transmission shifts too often underheavy loads and/or hilly conditions.
The tow/haul mode may be used if the transmissionshifts too often. SeeTow/Haul Mode on page 3!36.
When towing at high altitude on steep uphill grades,consider the following: Engine coolant will boil at alower temperature than at normal altitudes. If the engineis turned off immediately after towing at high altitude onsteep uphill grades, the vehicle may show signs similarto engine overheating. To avoid this, let the engine runwhile parked, preferably on level ground, with theautomatic transmission in P (Park) for a few minutesbefore turning the engine off. If the overheat warningcomes on, seeEngine Overheating on page 7!34.
Parking on Hills
{WARNING:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on
a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift intoP (Park) yet. Turn the wheels into the curb if facingdownhill or into traffic if facing uphill.
2. Have someone place chocks under the trailerwheels.
3. When the wheel chocks are in place, release theregular brakes until the chocks absorb the load.

4. Reapply the brake pedal. Then apply the parkingbrake and shift into P (Park).
5. Release the brake pedal.
{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 the engine has been left running, the vehicle
can move suddenly. You or others could be
injured. To be sure the vehicle will not move, even
when on fairly level ground, always put the shift
lever fully in P (Park) with the parking brake
firmly set.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine
3. Shift into a gear
4. Release the parking brake
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and storethe chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling atrailer. See this manual's Maintenance Schedule orIndex for more information. Things that are especiallyimportant in trailer operation are automatic transmissionfluid, engine oil, axle lubricant, belts, cooling systemand brake system. It is a good idea to inspect thesebefore and during the trip.
Check periodically to see that all hitch nuts and boltsare tight.
