{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
asmallamountofalcohol.You
can have a serious—or even
fatal—collision if you drive after
drinking.
Do not drink and drive or ride with
adriverwhohasbeendrinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.
Braking
Braking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.
Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.
Helpful braking tips to keep in mindinclude:
.Keep enough distance betweenyou and the vehicle in frontof you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.
Steering
Electric Power Steering
The vehicle has electric powersteering. It does not have powersteering fluid. Regular maintenanceis not required.
If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort. See your dealer ifthere is a problem.
If the steering wheel is turned until itreaches the end of its travel and isheld against that position for anextended period of time, powersteering assist may be reduced.
If the steering assist is used for anextended period of time, powerassist may be reduced.
Normal use of the power steeringassist should return when thesystem cools down.
See your dealer if there is aproblem.

The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
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.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
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. SeeTires0248.
.Turn off cruise control.

176 Driving and Operating
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.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0197.
.The Antilock Brake System(ABS) improves vehicle stabilityduring hard stops, but thebrakes should be applied soonerthan when on dry pavement.SeeAntilock Brake System(ABS)0195.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwise

Engine Oil
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.
Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0222.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.
If the engine oil pressure lightcomes on, check the engine oil levelright away. The oil pressure light ison the instrument cluster. SeeEngine Oil Pressure Light011 8.Check the engine oil level regularly;this is an added reminder.
Checking Engine Oil
Check the engine oil level regularly(every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0217for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center(DIC) message displays, check theoil level.

Manual Transmission
Fluid
It is not necessary to check themanual transmission fluid level.Atransmissionfluidleakistheonlyreason for fluid loss. If a leakoccurs, take the vehicle to yourdealer and have it repaired as soonas possible. SeeRecommendedFluids and Lubricants0300for theproper fluid to use.
Hydraulic Clutch
For vehicles with a manualtransmission, it is not necessary toregularly check brake/clutch fluidunless there is a leak suspected.Adding fluid will not correct a leak.Afluidlossinthissystemcouldindicate a problem. Have thesystem inspected and repaired.
When to Check and What
to Use
The common hydraulic clutch andbrake master cylinder fluid reservoiris filled with DOT 3 brake fluid asindicated on the reservoir cap. SeeEngine Compartment Overview0217for reservoir location.
How to Check and Add Fluid
Visually check the brake/clutch fluidreservoir to make sure the fluid levelis at the MIN (minimum) line on theside of the reservoir. The brake/hydraulic clutch fluid system shouldbe closed and sealed.
Do not remove the cap to check thefluid level or to top⇣off the fluid level.Remove the cap only whennecessary to add the proper fluiduntil the level reaches the MIN line.
Engine Air Cleaner/Filter
The engine air cleaner/filter islocated in the engine compartmenton the passenger side of thevehicle. SeeEngine CompartmentOverview0217for more informationon location.
When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing andinspecting the engine air cleaner/filter, seeMaintenanceSchedule0290.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have theengine running with the engine aircleaner/filter housing open. Beforeremoving the engine air cleaner/filter, make sure that the engine aircleaner/filter housing and nearbycomponents are free of dirt anddebris. Remove the engine aircleaner/filter. Lightly tap and shakethe engine air cleaner/filter (awayfrom the vehicle), to release loosedust and dirt. Inspect the engine aircleaner/filter for damage, andreplace if damaged.

Caution (Continued)
.Do not mix water withready-to-use washer fluid.Water can cause thesolution to freeze anddamage the washer fluidtank and other parts of thewasher system.
.When using concentratedwasher fluid, follow themanufacturer instructions foradding water.
.Fill the washer fluid tankonly three-quarters full whenit is very cold. This allowsfor fluid expansion iffreezing occurs, which coulddamage the tank if it iscompletely full.
Brakes
Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or can
be heard all the time when thevehicle is moving, except whenapplying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
acrash.Whenthebrakewear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.
Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear and
evenly tighten wheel nuts in theproper sequence to torquespecifications. SeeCapacities andSpecifications0304.
Brake pads should be replaced ascomplete sets.
Brake Pedal Travel
See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service may be required.
Replacing Brake System Parts
Always replace brake system partswith new, approved replacementparts. If this is not done, the brakesmay not work properly. The brakingperformance expected can changein many other ways if the wrongreplacement brake parts areinstalled or if parts are improperlyinstalled.
