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.

Driving and Operating 275
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

for the cooling system. See
Recommended Fluids and
Lubricants0377.
Never dispose of engine coolant byputting it in the trash, or by pouringit on the ground, or into sewers,streams or bodies of water. Havethe coolant changed by anauthorized service center, familiarwith legal requirements regardingused coolant disposal. This will helpprotect the environment and yourhealth.
Checking Coolant
The vehicle must be on a levelsurface when checking the coolantlevel.
Check to see if coolant is visible inthe coolant surge tank. If the coolantinside the coolant surge tank isboiling, do not do anything else untilit cools down.
If coolant is visible but the coolantlevel is not at or above the markpointed to, add a 50/50 mixture ofclean, drinkable water andDEX-COOL coolant.
Be sure the cooling system is coolbefore this is done.
If no coolant is visible in the coolantsurge tank, add coolant as follows:
How to Add Coolant to the
Coolant Surge Tank
{Warning
Yo u c a n b e b u r n e d i f y o u s p i l l
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.

3. Fill the coolant surge tank withthe proper mixture to the markpointed to on the coolantsurge tank.
4. With the coolant surge tankcap off, start the engine and letit run until the upper radiatorhose starts getting hot. Watchout for the engine cooling fan.By this time, the coolant levelinside the coolant surge tankmay be lower. If the level islower, add more of the propermixture to the coolant surge
tank until the level reaches themark pointed to on the coolantsurge tank.
5. Replace the cap tightly.
Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has an engine coolanttemperature gauge on theinstrument cluster to warn of engineoverheating. SeeEngine CoolantTe m p e r a t u r e G a u g e011 9.

fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam Is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
(Continued)
Warning (Continued)
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not betoo serious. Sometimes the enginecan get a little too hot when thevehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayedwith no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral), and let theengine idle.
If the engine coolant temperaturegauge is no longer in the overheatzone, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safedistance from the vehicle in front.If the warning does not come backon, continue to drive normally andhave the cooling system checkedfor proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is no sign of steam, idle theengine for three minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.
