250 Driving and Operating
Curve Tips
.Ta k e c u r v e s a t a r e a s o n a b l espeed.
.Reduce speed before entering acurve.
.Maintain a reasonable steadyspeed through the curve.
.Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.
Steering in Emergencies
.There are some situations whensteering around a problem maybe more effective than braking.
.Holding both sides of thesteering wheel allows you to turn180 degrees without removingahand.
.Antilock Brake System (ABS)allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:
1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.
2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.
3. Turn the steering wheel to gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids thatcorrespond to the vehicle's threecontrol systems:
.Braking Skid—wheels are notrolling.
.Steering or Cornering Skid—too much speed or steering in acurve causes tires to slip andlose cornering force.
.Acceleration Skid—too muchthrottle causes the drivingwheels to spin.
Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.
If the vehicle starts to slide, followthese suggestions:
.Ease your foot off theaccelerator pedal and steer theway you want the vehicle to go.

Driving and Operating 255
Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Driving in Water
{Warning
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers
could drown. If it is only shallow
water, it can still wash away the
ground from under your tires.
(Continued)
Warning (Continued)
Traction could be lost, and the
vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes and thevehicle can stall. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads”later in thissection.
After Off-Road Driving
Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.
After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.
More frequent maintenance serviceis required. See theMaintenanceSchedule0452.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

Do not exceed the maximumallowable tongue weight for thevehicle. Choose the shortest hitchextension that will position the hitchball closest to the vehicle. This willhelp reduce the effect of trailertongue weight on the rear axle.
Trailer rating may be limited by thevehicle's ability to carry tongueweight. Tongue or kingpin weightcannot cause the vehicle to exceedthe GVWR (Gross Vehicle WeightRating) or the RGAWR (Rear GrossAxle Weight Rating). See“To t a lWeight on the Vehicle's Tires”laterin this section.
After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.
If a cargo carrier is used in thetrailer hitch receiver, choose acarrier that positions the load asclose to the vehicle as possible.Make sure the total weight,including the carrier, is no more thanhalf of the maximum allowabletongue weight for the vehicle or227 kg (500 lb), whichever is less.

Total Weight on the Vehicle's
Tires
Be sure the vehicle's tires areinflated to the inflation pressuresfound on the Certification/Tire labelon the center pillar or seeVehicleLoad Limits0259.Makesurenottoexceed the GVWR limit for thevehicle, or the RGAWR, with the towvehicle and trailer fully loaded forthe trip including the weight of thetrailer tongue. If using aweight-distributing hitch, make surenot to exceed the RGAWR beforeapplying the weight distributionspring bars.
Weight of the Trailering
Combination
It is important that the combinationof the tow vehicle and trailer doesnot exceed any of its weightratings—GCWR, GVWR, RGAWR,Trailer Weight Rating, or TongueWeight. The only way to be sure it is
not exceeding any of these ratingsis to weigh the tow vehicle andtrailer combination, fully loaded forthe trip, getting individual weightsfor each of these items.
Towing Equipment
Hitches
The correct hitch equipment helpsmaintain combination control. Manytrailers can be towed with aweight-carrying hitch which simplyfeatures a coupler latched to thehitch ball, or a tow eye latched to apintle hook. Other trailers mayrequire a weight-distributing hitchthat uses spring bars to distributethe trailer tongue weight among thetow vehicle and trailer axles.Fifth-wheel and gooseneck hitchesmay also be used. See“Weight ofthe Trailer Tongue”underTr a i l e rTo w i n g0318for rating limits withvarious hitch types.
If a step-bumper hitch will be used,the bumper could be damaged insharp turns. Make sure thereis ample room when turning to avoidcontact between the trailer and thebumper.
Consider using sway controls withany trailer. Ask a traileringprofessional about sway controls orrefer to the trailer manufacturer'srecommendations and instructions.
Weight-Distributing Hitch and
Adjustment
Aweight-distributinghitchmaybeuseful with some trailers. Use thefollowing guidelines to determine if aweight-distributing hitch shouldbe used.

for details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0415.
With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.
If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
Low-Profile Tires
If the vehicle has P275/55R20,
P285/50R20, or P285/45R22
size tires, they are classified as
low-profile tires.
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can
occur when coming into contact
with road hazards like potholes,
or sharp edged objects, or when
sliding into a curb. The warranty
does not cover this type of
damage. Keep tires set to the
correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other road
hazards.
All-Terrain Tires
This vehicle may have all-terraintires. These tires provide goodperformance on most road surfaces,weather conditions, and for off-roaddriving. SeeOff-Road Driving0251.
The tread pattern on these tires maywear more quickly than other tires.Consider rotating the tires morefrequently than at 12 000 km(7,500 mi) intervals if irregular wearis noted when the tires areinspected. SeeTireInspection0411.
Tire Sidewall Labeling
Useful information about a tire is
molded into the sidewall. The
examples show a typical
passenger and light truck tire
sidewall.

number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item C of the tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.

(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0405.

406 Vehicle Care
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits0259.Howthe
vehicle is loaded affects vehicle
handling and ride comfort. Never
load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
Do not forget the spare tire,
if the vehicle has one. See
Full-Size Spare Tire0431for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
