while starting the vehicle, damage
may occur to the power steering
system and there may be loss of
power steering assist.
Place the transmission in theproper gear.
Automatic Transmission
Move the shift lever to P (Park) orN(Neutral). To restart the enginewhen the vehicle is already moving,use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the

The shift lever should be in Neutraland the parking brake engaged.Hold the clutch pedal down to thefloor and start the engine.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition key to START. Whenthe engine starts, let go of thekey. The idle speed will godown as the engine gets warm.Do not race the engineimmediately after starting it.
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the low fuel warning lightis on and the FUEL LEVELLOW message is displayed inthe Driver Information Center(DIC), hold the ignition switchin the START position tocontinue engine cranking.

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.

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
