Hybrid Features
Hybrid Vehicle Operation
The hybrid vehicle combinesgasoline and electric propulsion todrive the vehicle. The gas enginewill automatically start to providepower. It will shut off to save fuel.The engine may remainrunning when:
.There is aggressive accelerationor climbing hills.
.Vehicle speed is greater than88 km/h (55 mph).
.The high voltage battery ischarging.
.The heater is being used.
The engine and transmission worktogether to provide the requiredpower at the highest efficiency. Thismay result in higher engine speeds.SeeDriving for Better FuelEconomy029.
High Voltage Safety

Driving and Operating 219
Hydroplaning
Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.
There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wetweather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wipingequipment in good shape.
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0317.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.
.Be alert on top of hills;something could be in your lane(e.g., stalled car, accident).
.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.

274 Driving and Operating
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move your hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal so thetrailer will not strike soft shoulders,curbs, road signs, trees, or otherobjects. Use the turn signal well inadvance and avoid jerky or suddenmaneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on theinstrument cluster flash wheneversignaling a turn or lane change.Properly hooked up, the trailerlamps also flash, telling otherdrivers the vehicle is turning,changing lanes, or stopping.
When towing a trailer, the arrows onthe instrument cluster flash for turnseven if the bulbs on the trailer areburned out. Check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergear before starting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might have to be used somuch that they would get hot and nolonger work well.
The vehicle can tow in D (Drive).Use a lower gear if the transmissionshifts too often.
When towing at high altitude onsteep uphill grades, engine coolantboils at a lower temperature than atnormal altitudes. If the engine isturned off immediately after towingat high altitude on steep uphillgrades, the vehicle could showsigns similar to engine overheating.To a v o i d t h i s , l e t t h e e n g i n e r u nwhile parked, preferably on levelground, with the transmission inP(Park) for a few minutes beforeturning the engine off. If theoverheat warning comes on, seeEngine Overheating0297.
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 donot shift into P (Park) yet. Turnthe wheels into the curb iffacing downhill or into traffic iffacing uphill.
2. Have someone place chocksunder the trailer wheels.
3. When the wheel chocks are inplace, release the brake pedaluntil the chocks absorbthe load.
4. Reapply the brake pedal. Thenapply the parking brake andshift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedalwhile you:
1.1. Start the engine.
1.2. Shift into a gear.
1.3. Release the parkingbrake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer isclear of the chocks.
4. Stop and have someone pickup and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service moreoften when pulling a trailer. See theMaintenance Schedule0369.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, andbrake system. Inspect these beforeand during the trip.
Check periodically to see that allhitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarilyoverheat during severe operatingconditions. SeeEngineOverheating0297.
Trailer Towing
Before pulling a trailer, threeimportant considerations have to dowith weight:
.Weight of the trailer.
.Weight of the trailer tongue.
.To t a l w e i g h t o n y o u r v e h i c l e ' stires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than454 kg (1,000 lb). But even that canbe too heavy.
It depends on how the rig is used.For example, speed, altitude, roadgrades, outside temperature, andhow much the vehicle is used to pullatrailerareallimportant.Itcandepend on any special equipmenton the vehicle, and the amount oftongue weight the vehicle can carry.See“Weight of the Trailer Tongue”following.
Maximum trailer weight is calculatedassuming the tow vehicle has thedriver, a front seat passenger and

Check to see if coolant is visible inthe power electronics coolantreservoir. If coolant is visible but thecoolant level is below the cold fillline, there could be a leak in thecooling system.
The power electronics coolantshould only be serviced by aqualified technician.
Engine Coolant
The cooling system in the vehicle isfilled with DEX-COOL®enginecoolant mixture. SeeRecommendedFluids and Lubricants0377andMaintenance Schedule0369.
The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,seeEngine Overheating0297.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Use a 50/
50 mixture of clean, drinkable
water and DEX-COOL coolant.
Use a 50/50 mixture of clean,drinkable water and DEX-COOLcoolant. If using this mixture,nothing else needs to be added.
This mixture:
.Gives freezing protection downto✓37 °C (✓34 °F), outsidetemperature.
.Gives boiling protection up to129 °C (265 °F), enginetemperature.
.Protects against rust andcorrosion.
.Will not damage aluminum parts.
.Helps keep the proper enginetemperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
