This power mode is available forservice and diagnostics, and toverify the proper operation of themalfunction indicator lamp as maybe required for emission inspectionpurposes. With the vehicle off, andthe brake pedal not applied,pressing and holding ENGINESTART/STOP for more thanfive seconds will place the vehicle inService Only Mode. The instrumentsand audio systems will operate asthey do in ON/RUN, but the vehiclewill not be able to be driven. Theengine will not start in Service OnlyMode. Press ENGINE START/STOPagain to turn the vehicle off.
Starting the Engine
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
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical
Equipment0211.
Manual Transmission
The shift lever should be in Neutraland the parking brake engaged.Hold the clutch pedal to the floorand start the engine.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition to START. When theengine cranks, let go of thekey. The idle speed will godown as the engine gets warm.
Caution
Holding the key in START for
longer than 15 seconds at a time
will cause the battery to be

Up-Shift Light
Vehicles equipped with a manualtransmission have an up-shift light.This light indicates when to shift tothe next higher gear for better fueleconomy.
For the best fuel economy,accelerate slowly and shift when thelight comes on, and if the weather,road, and traffic conditions allow.
It is normal for the light to go on andoff if the accelerator positionchanges quickly. Ignore the lightduring downshifts.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) WarningLight011 5.
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

196 Driving and Operating
Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Parking Brake
To s e t t h e p a r k i n g b r a k e , h o l d t h ebrake pedal down and pull up on theparking brake lever. If the ignition ison, the brake system warning lightwill come on. SeeBrake SystemWarning Light011 4.
To r e l e a s e t h e p a r k i n g b r a k e , h o l dthe brake pedal down. Pull theparking brake lever up until you canpress the release button. Hold therelease button in as you move thebrake lever all the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
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.

Cruise Control
If the vehicle is equipped with cruisecontrol, a speed of about 40 km/h(25 mph) or more can be maintainedwithout keeping your foot on theaccelerator. Cruise control does notwork at speeds below 40 km/h(25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
asteadyspeed.Donotuse
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle's Traction ControlSystem (TCS) or StabiliTrak systembegins to limit wheel spin whileusing cruise control, the cruisecontrol will automatically disengage.
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.Ifacollisionalert occurs when cruise control isactivated, cruise control isdisengaged. SeeForward CollisionAlert (FCA) System0204.Whenroad conditions allow you to safelyuse it again, the cruise control canbe turned back on.
If the brakes are applied, cruisecontrol disengages.

The speedometer reading can bedisplayed in either English or metricunits. SeeDriver Information Center(DIC)0121.Theincrementvalueused depends on the unitsdisplayed.
Passing Another Vehicle WhileUsing Cruise Control
Use the accelerator pedal toincrease the vehicle speed. Whenyou take your foot off the pedal, thevehicle slows down to the previousset cruise control speed. Whilepressing the accelerator pedal orshortly following the release tooverride cruise control, brieflymoving the thumbwheel towardSET/- will result in cruise control setto the current vehicle speed.
Using Cruise Control on Hills
How well cruise control works onhills depends on the vehicle speed,load, and the steepness of the hills.When going up steep hills, youmight have to step on theaccelerator pedal to maintain thevehicle speed. When goingdownhill, you might have to brake orshift to a lower gear to keep your
speed down. If the brake pedal isapplied, cruise control willdisengage.
Ending Cruise Control
There are four ways to end cruisecontrol:
.To d i s e n g a g e c r u i s e c o n t r o l ,step lightly on the brake pedal orclutch for manual transmission.
.Press*.
.Shift the transmission toN(Neutral).
.To t u r n o f f c r u i s e c o n t r o l ,
