Defensive Driving
Defensive driving means“alwaysexpect the unexpected.”The firststep in driving defensively is to wearthe safety belt. SeeSafetyBelts066.
.Assume that other road users(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.
.Allow enough following distancebetween you and the driver infront of you.
.Focus on the task of driving.
Drunk Driving
Death and injury associated withdrinking and driving is a globaltragedy.
{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 (1500
Series)
If 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 in that position for an extendedperiod of time, power steering assistmay 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.

Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After youcompletely stop and hold the vehiclein a complete standstill on a grade,HSA will automatically activate.During the transition period betweenwhen you release the brake pedaland start to accelerate to drive offon a grade, HSA holds the brakingpressure for a maximum oftwo seconds to ensure that there isno rolling. The brakes willautomatically release when theaccelerator pedal is applied withinthe two-second window. If thevehicle is equipped with theIntegrated Trailer Brake Control(ITBC) system, HSA may also applythe trailer brakes. It will not activateif the vehicle is in a drive gear and
