Suzuki Grand Vitara: Trailer Towing - Vehicle Loading and Towing - Suzuki Grand Vitara Owner's ManualSuzuki Grand Vitara: Trailer Towing

You can use your SUZUKI to tow a trailer, but you should always observe the requirements and recommendations in this section. If you intend to tow a trailer, it is essential to select a trailer and trailer towing equipment which are compatible. A reputable trailer dealer can help you.

CAUTION: Trailer towing puts additional stress on the engine, drive train and brakes of your vehicle. Never tow a trailer during the first 960 km (600 miles) of vehicle operation.

CAUTION: Because towing a trailer puts additional stress on your vehicle, more frequent maintenance will be required than under normal driving conditions. Follow the schedule for Maintenance Recommended Under Severe Driving Conditions or perform more frequent maintenance as necessary.

For Automatic transmission vehicles, shift into “3” (Low 2) or “L” (Low 1) (if necessary) and frequently monitor the coolant temperature gauge when towing up a steep hill. If the gauge indicates overheating, park the vehicle in a safe place and let the engine cool down. Refer to “If the Engine Overheats” section for details on how to deal with overheating.

CAUTION: Towing in “D” range up a steep hill can cause coolant overheating which may result in engine/automatic transmission damage.

Hitches

Use only a trailer hitch bracket that is designed to bolt to the frame of your vehicle, and a hitch that is designed to bolt to this bracket. We recommend that you use a genuine SUZUKI trailer hitch bracket and trailer hitch (available as options), or equivalent.

or a hitch which attaches to the axle of your vehicle. WARNING: Never use a bumper hitch or a hitch which attaches to the axle of your vehicle.

Safety Chains

Always attach safety chains between your vehicle and trailer. Cross safety chains under the tongue of the trailer so that the tongue will not drop to the road if the trailer becomes separated from the hitch. Follow the manufacturer’s recommendation for attaching safety chains. Always leave just enough slack to permit full turning. Never allow safety chains to drag on the road.

Tires

it is very important for your vehicle and trailer to have properly inflated tires. WARNING: When towing a trailer, it is very important for your vehicle and trailer to have properly inflated tires. Your vehicle’s tires should be inflated to the recommended pressures listed on your vehicle’s Tire Inflation Pressure label. Inflate trailer tires according to the specifications provided by the trailer manufacturer.

Mirrors

Check to see if your vehicle’s mirrors meet federal, state and local requirements for mirrors used on towing vehicles. If they do not, you must install required mirrors before you tow.

Vehicle/Trailer Weight Limits

Before towing, you must make sure that gross trailer weight, gross combined weight, trailer tongue weight, gross vehicle weight and gross axle weight (front and rear) are within specified limits as described below. You can measure vehicle and trailer weights using a vehicle scale and can measure tongue weight using a bathroom scale.

Weight
Gross Trailer Weight

Gross Trailer Weight is the weight of the trailer plus all cargo in it (measured with the trailer disconnected from the towing vehicle). Gross trailer weight must never exceed 1350 kg (3000 pounds). If you intend to tow a trailer having a gross trailer weight greater than 450 kg (1000 pounds), the trailer must be equipped with trailer brakes.

Weight
Gross Combined Weight

Gross Combined Weight is the weight of the fully loaded vehicle (including all the occupants, accessories and cargo) plus the weight of the fully loaded trailer. Gross combined weight must never exceed:
• 2WD – 3400 kg (7500 pounds).
• 4WD – 3450 kg (7600 pounds).

Tongue Weight is the downward force exerted on the hitch by the trailer coupler,
Tongue Weight

Tongue Weight is the downward force exerted on the hitch by the trailer coupler, with the trailer fully loaded and the coupler at its normal towing height. Cargo should be distributed so that tongue weight is approximately 10% of gross trailer weight.

NOTE: You can usually get tongue weight to be about 10% of gross trailer weight by placing about 60% of the total cargo weight in the front half of the trailer. You should measure gross trailer weight and tongue weight before towing, however, to make sure that your load is properly distributed.

Weight
Gross Vehicle Weight

Gross Vehicle Weight is the weight of the fully loaded vehicle (including all the occupants, accessories and cargo plus the trailer tongue weight). The gross vehicle weight must never exceed the Gross Vehicle Weight Rating (GVWR) listed on the Safety Certification Label.

Gross Axle Weight (Front and Rear) is the weight supported by an individual axle

differently when towing a trailer. For your safety and the safety of others, you WARNING: Your vehicle will handle differently when towing a trailer. For your safety and the safety of others, you should observe the following precautions:
• Practice turning, stopping and backing up before you begin towing in traffic. Do not tow in traffic until you are confident that you can handle the vehicle and trailer safely.
• Never exceed posted towing speed limits or 72 km/h (45 mph), whichever is lower.
• Never drive at a speed that causes shaking or swaying of the trailer. If you notice even the slightest sign of shaking or swaying, slow down.
• Always have someone guide you when backing.
• Allow adequate stopping distance. Stopping distance is increased when you tow a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and trailer length between you and the vehicle ahead. Follow at a greater distance if roads are wet or slippery.
• Slow down when making turns. Remember that a larger than normal turning radius is needed because the trailer wheels will be closer than the vehicle wheels to the inside of the turn.
• Avoid sudden acceleration and stopping of the vehicle. Do not make quick maneuvers unless they are necessary.
• Slow down in cross winds and be prepared for wind blasts from large passing vehicles.
• Be careful when passing other vehicles. Be sure to allow enough room for your trailer before you change lanes, and signal well in advance.
• Slow down and shift into a lower gear before you reach long or steep downhill grades. It is hazardous to attempt downshifting while you are descending a hill.
• Avoid “riding” the brakes. “Riding” the brakes could cause the brakes to overheat, resulting in reduced braking efficiency. Use engine braking as much as possible.
• Because of the added trailer weight, your engine may overheat on hot days when going up long or steep hills. Pay attention to your engine temperature gauge. If it indicates overheating, pull off the road and stop in a safe place. Refer to the “If the Engine Overheats” in “EMERGENCY SERVICE” section for details on how to proceed.
